Advice? Going a bit insane.

I have a simple set-up I've been trying to get running stable for about a week now. I have 2x nVIDIA GTX 980 and 2x Radeon 29 280X cards that I want to use.
I have previously used just the GTX 980s and they were stable for weeks. I recently acquired the 280s, and while I can't be certain, I think the cards are not at issue.
I also had two of the 980s and one 280 running in my desktop stable for quite some time, just as a tester. But for the actual mining rig, I was using old AMD AM3-based hardware. And I've had nothing but problems. Murphy's law.
First, I had a motherboard go out (ASUS M4A87TD EVO.) Luckily I had a spare. But the ASUS board had two native PCI-E x16 slots (one running at x1 speed,) and so I had been running the 980s both in the motherboard, and was using this riser extender to run the other cards, with molex->SATA risers (I don't have enough native 4-pin connectors to run without molex to SATA adapters.)
The "new" board (which is actually chronologically older and older tech) is a Gigabyte GA-MA785GM-US2H. It's also socket AM3 but only supports DDR2 memory; luckily I had old DDR2 available. This board also only has one x16 slot, so I am running 3 GPUs outside of the chassis with x16 risers.
It turns out after some nightmare of troubleshooting that one of the DDR2 DIMMs is probably bad. I don't have a replacement at the moment, but I've tried running everything with one DIMM.
I also have Virtual Memory (swap/page file) set to 16GB. I don't know why this is necessary, but other people mention it and NiceHash wouldn't let me run 4 cards without it.
Anyway, all works "fine;" I have the 280s set to 850MHz core clock and +20 power with 100% fans, and 100% fans and native clock on the 980s.
But I keep getting crashes. Before I had freezes, so I also changed out power supplies several times and tried everything you can think of. I don't think the issue is down to power any more, but I'm open to correction if anyone has a suggestion or tip.
For power, I'm using a 3 to 1 ATX-24 pin adapter, with a SeaSonic 620W as the master, and a Corsair 550W as the "slave." The SeaSonic powers the motherboard and the ATX12V for the CPU. It also powers the 3 SATA to molex adapters for the x16 risers, and the 8+6 pin PCI-E power connectors for the 280s.
The Corsair powers the HDD (this I have also suspected of causing problems but I have swapped HDDs and had the same issues, and I really need to get an SSD for this thing,) two 120mm intake fans, two 140mm exhaust fans, and the 6 pin PCI-E connectors for the 980s.
It doesn't seem to freeze anymore. It will mine just fine for a while but eventually I will get a BSOD, usually saying that the device driver has gone into an infinite loop. I believe this is the Crimson driver (I am using version 15.12.)
I've swapped CPUs and memory and HDDs and motherboards and I'm just almost at my wits' end about to tear my hair out trying to get this thing to run stably. I most likely just need to get all new mainboard/CPU/memory, but I can't do that at the moment, so I am looking for any advice/help I can get.
I would assume the driver is going into an infinite loop because it's polling hardware and not getting the response it expects or something like that, which could indicate a power or heat issue, but I don't know. And I've searched for the BSOD error and 90% of the results for "device driver went into an infinite loop" (paraphrasing) were related to AMD Crimson drivers. So that's been where my suspicion has been so far, and I've had other problems with getting the AMD stuff to work when I was initially setting it up. (And had problems with AMD/ATi drivers going back 20 years, ugh.)
So.. Any advice?
TL;DR: Running 2x GTX 980 and 2x R9 280X; keep getting BSOD about device driver going into an infinite loop after some time mining. Want to stab myself.

Of Wolves and Weasels - Day 259 - Guest Post: Clarifications and Thoughts on Dogeparty and the Community

Hey all, GoodShibe... on Vacation!
Today's Guest Post comes to us from pseudopseudonym and they've put a lot of work into it, so please lend them your ears [eyes?] ;D)
Disclosure statement: I am not a Dogeparty or Dogecoin developer. I am currently holding a total of 98.566 XDP and own 55 Dogeparty assets, none of which I have profited from (nor plan to profit from) in any way. I recently took on the role of Community Manager for Dogeparty, which is an unpaid position.
I have been involved in Dogecoin since the fairly early days and have always been proud to be part of this community, even in a small way. Like many of you I’ve seen us grow and blossom through various events, and recently shared in the pain of loss with you all. My experience with Dogecoin so far consisted of mining hundreds of thousands of Dogecoin with a Radeon 7970, purchasing an R9 280X and never getting to use it due to being hospitalized. In my entire time in the Dogecoin community, one of the most controversial things I witnessed was Dogeparty.
Many aspects of Dogeparty have created confusion. For the first week or so it was discussed on the subreddit, I viewed it as a weird distraction that I couldn’t properly understand. Over time various aspects of it became clear to me - Proof of Burn, what it was to be used for, the relationship (or lack thereof) that it had with Dogecoin and why Dogecoin was being used by the developers. If you’re currently confused, hopefully this post is for you!
Dogecoin and Dogeparty are both very new technologies and are somewhat experimental. Dogeparty builds on the Dogecoin blockchain and enables for the secure transmission of tokens and assets between users, as well as a lot of other cool stuff. Assets can be used for just about any purpose you can think of; and cost 0.5 XDP to produce. Just over a month ago, a “burn” period was started where people could send DOGE to a provably unspendable address in exchange for XDP. About 1.85 billion DOGE was exchanged for XDP over that burn period. You can read more about Dogeparty and what it does on the Dogeparty website - it does a better job of explaining it than I can.
Exchanging DOGE for XDP serves a single purpose: creating value for the XDP tokens. It is not intended as a way of reducing inflation for Dogecoin, nor is it a way of taking DOGE away from Dogecoin users. As a result of the burn, there is now plenty of XDP to go around, which will hopefully enable lots of innovative projects in the future. We’ve already seen a lot of interesting things going on in Counterparty - Storj, LTBcoin and Swarm just to name a few.
Lots of exciting things are happening with Dogeparty right now. With the burn over, the decentralized exchange in Dogeparty should be coming online soon, and many of the initial teething issues Dogeparty faced are over. There is still a lot of work to be done, and it’s early days for Dogeparty - if you want to help, feel free to join the Skype discussion, use Dogeparty and report bugs to the project on GitHub.
Recently a post was made by a prominent community member sharply criticizing Dogeparty in various ways. While the post was largely dismissed, it raised some points that need addressing.
We’re always seeking new developers and contributors. If you’re interested in helping out, we’d love to hear from you, especially if you know Python!
As ever, I’m excited to be on this rocket with you all, and I look forward to seeing everything the community can do. If you have any questions about Dogeparty or just want to chat, feel free to ask in the Skype chat or on IRC (I’m Gnomethrower on #dogecoin) or right here on Reddit. I’ll do my best to answer any questions you have, and relay anything I can’t to the Dogeparty team. I will leave you with this thought: “If we turn a blind eye to that which we do not know, we will never see past the horizon”.
With the amount of technologies and talent in the Dogecoin community, I can’t wait to see what we’ll do next. To the moon!
It's 8:03AM EST and we've found 92.97% of our first 100 Billion DOGEs - only 7.03% remains until we reach our soft cap! Our global hashrate is on the rise from ~744 to ~769 and our difficulty is up from ~7215 to ~9391.
As always, I appreciate your support!

Made $1 Million mining. Want to Cash out. worried about being unemployed

Basically back in early 2016, I bought some second hand Radeon 7970s and r9 280x and been mining ETH since it pretty much launched. Back then you basically made like 1 ETH per GPU per day. Back then a 280x mined at like 27MH/s since the DAG was very small. Even my R9 270X mined at like 20MH/s.
I kept all this ETH, along with the free ETC, sold all of my ETH/ETC when it peaked at $400 last Summer and went all in BTC. BTC went 5x since that time. Also got the free bitcoin forks.
I kept cashing out a small amount with bitcoin ATMs and basically quit my job since it wasn't worth the hassle.
Now I want to buy a house but I am worried about sending $1,000,000 to an exchange like Gemini/Coinbase/Kraken/Bitstamp and have them freeze this BTC.
I am worried they will ask for employment papers and I've been unemployed since 2016.
All this money was made legally. However since I mined to an exchange instead of my personal ETH wallet, I might not be able to provide a signed message proving I am the one who mined those coins. Since all the coins were mined directly to my Poloniex account. I do have receipts for some RX 470s that I bought last year and wondering if its sufficent. Do I need to take photos of my mining rigs and show it to my exchange as proof?
I know I can buy USDT tether but I am worried that its not really backed by anything. I also don't know if any of the Bitcoin Future Options will be sufficient since they might carry crazy premiums for the puts.
Wondering if people had issues withdrawing large amounts.

Legacy BIOS overwritten on my Radeon R9 280X

Just bought a Radeon R9 280X off ebay. The guy said the BIOS had been over written but it turns out both the bios and legacy bios are over written with some custom bitcoin mining software for linux. Any idea how i can re flash it ? (links to foums etc would be helpful)

Get my mining rig to boot, I'll pay you +$30 in bitcoin right now!

Whoever get's my mining rig to boot up and get mining properly, will be sent +$30 in bitcoin instantly from my coinbase account. I have bitcoin ready to be sent as soon as my system is up and running. Please take a look at the info below and reply with a solution! First person to fix my rig will be sent the bitcoin!
The setup:
MOBO: ASRock Fatal1ty Z87 Killer LGA 1150 Intel Z87 CPU:Intel Pentium G3220 Haswell 3.0GHz LGA 1150 PSUs: 2x EVGA SuperNOVA 1000 G2 80 PLUS GOLD Certified 1000W GPUs: 2x SAPPHIRE 11197-03-CPO Radeon HD 7970 3GB 3x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB Memory: 2x 4GB DDR3 1600mhz Corsair Vengence Other: 16x and 1x molex powered risers, add2psu adapter
I have three gigabyte windforce gpu's and two sapphire 7970 cards. For some reason I cannot get my rig to boot with 4 gpu's or more. I got my rig to boot into win8.1 a day ago with 4 gpu's but after restarting it, It refused to post again. I have risers on all the slots and have tried configurations with the gpu's in different slots. I have jumped the A1 and B17 pins on two of the 1x pci-e slots (last two 1x slots furthest from the cpu) and jumped the A1 and B81 pins on three 16x pci-e slots. I've tried configs with two 280x gpu's on 16x risers and with two 7970 gpu's on 1x risers. I've also tried three 280x gpu's on 16x risers and one 7970 gpu on a 1x riser. I've tried many similar configs but I have had little to no luck. Im using dual psu's with the add2psu adapter. They're the same evga 1000w psu's. All the risers are powered too. And I do receive 5 beeps as an error code through the mobo speaker when I try to boot sometimes. If not, the fans just get loud and the system never boots. All the graphics cards are plugged into the primary psu and so are all the molex cables powering the gpu risers. The second psu only has a single 24 pin cable being plugged into the add2psu adapter.
Working solutions will be rewarded! Thanks :D

[Build Ready] Never built a PC, looking for advice

After asking on some other forums and looking at various articles, I have picked out a tentative parts list. I figured I would ask for some second opinions from a different forum before I started the actual shopping.
Some things to note;
Budget: My original budget was 800-1200 USD -- this includes OS/peripherals/monitoaccessories and maybe a chair if I have the money leftover for it. I already have a Samsung LCD TV for big picture stuff. I thought this was a good range for the performance that I want (though I could be wrong). It looks like I'm going to be over after the aforementioned extras, but I'm not that fussed since my TF2 pack is basically paying for everything.
I'm not overclocking (don't need it), but I did pick some overclock-ready parts since they weren't that much more expensive. This is going to be my only computer for a while, and I was advised that overclocking later can increase PC lifespan
Purpose: gaming, with some movies and light schoolwork (typing etc.). I'm not going to be rendering video, streaming, or any other intensive activities. I also heard bitcoin mining was no longer profitable due to electricity costs.
Benchmark games: Titanfall, Evil Within, Borderlands; The Pre-Sequel(split screen), Metro: Redux, etc. I'm going to be playing a mix of new and old releases, and I don't need maximum settings or 200 FPS. This is going to be my only computer for a while, however, so the more stuff it can handle, the better.
Previous computer building experience: zero (unless you count that one middle school project). I did watch that newegg youtube tutorial and read that one reddit guide, but other than that I'm still pretty new to this.
Other notes: Space is not a concern. I have a decently sized desk and won't be moving any time soon.

'Radeon R9 280X Gaming' crashes when I start playing games

Describe your problem. List any error messages and symptoms. Be descriptive.
I've really only used this desktop for school, but now am switching over to start gaming on it. However, once I start playing a game (like Overwatch) it the screen starts to flicker a bit and then a couple minutes later will go black screen with the computer still running in the back. I cannot click anything, but sometimes I can still hear the game music playing but black screen.
I am able to browse internet, youtube, etc. It's just crashing when I start doing something intensive like playing a game
List anything you've done in attempt to diagnose or fix the problem.
I tried following this guide to flash but the program has some bug in it every time I try it messes up. I've opened up the computer and looked at all the connections and they are set.
Provide any additional details you wish below.
The GPU was preowned, they used it for bitcoin mining briefly, I'm not sure what they did with its settings like overclocking since I don't know much about that and I am not able to reach them either. I also looked at MSI afterburner to see if it was maybe overheating, but it seemed to just be getting up to 47c so I don't think that is the issue either.

May I ask for some PSU suggestions at two different draw points that won't break the bank?

For my first build, I ended up having to use a lot of hand-me-down parts which my friends donated to me; I'll list which are new and which were 'previously-loved' as well as the capacity at which they were used.
New~
HyperX 16GB DDR3 RAM
480GB Mushkin Triactor SSD
Used~
Thermaltake case
Intel i-5 3750K
GA-Z77-DS3H Motherboard
LSP ULTRA 650 W PSU
Radeon R9 280X GPU
The case, processor, MOBO, and PSU were used in an office environment as a video and image editing workstation. The graphics card was formerly used to mine bitcoin a couple of years ago.
My dad and I finally got the rig put together and running last night, and I took it up to my room to start installing Windows, but after I left it on for about half an hour, I came back to a room reeking of burnt plastic and actually burnt myself touching the PSU. Anyone know how to fix this?
Barring that, is there a suitable, reliable power supply anyone could suggest that won't completely drive me broke? I'd be looking for one at this power draw point at the moment, but my buddy who gave me the GPU said he'd give me another one of the same kind if I upgraded the PSU, so I guess I'm also looking for PSU suggestions for a dual GPU array later down the line.

[CANADA-BC] [H] Crypto Currency Mining Enclosure and hardware FULL setup sale [W] $ or Bitcoin

I own a crypto currency mining investment company and I'm selling off the current hardware setup. It has been in use since mid-March of 2014. I've had a series of unfortunate events occur in my personal life that require me to sell off my business's hardware and other personal items.
This is for a firm priced sale, I am looking for a buyer that is either wanting to get into the mining business and wants a GPU based setup that can tackle all the new algorithms VS ASIC based setups that go obsolete within months and have no resale value. Or a buyer that wants to expand their mining farm or mining business and would love a plug-n-play type setup where the only thing they are required to do is have one power feed wired into their warehouse or home panel. This would be for local pickup only most likely. It will require the buyer to have a truck or to rent a u-haul type of moving truck. The system is roughly 60 inches tall by 95 inches long by 24 inches wide, not sure on its weight but moveable if the cards are removed(the cards are designed to be plug-n-play as well, no screws, just pop out pop in.) and runs at 240v for PC hardware and 120v for fans/misc regular appliance plugins(routers/switches etc).
The enclosure houses 8 systems which consist of 46 R9 280x video cards (it has room for expansion), has its own built in surge protection system to withstand lightning and other outside-the-enclosure based surges, whole system runs at 240v for best efficiency, has a 100amp breaker panel which is attached to the enclosure for maximum expansion.
The enclosure has 6x20 inch box fans which provide the 24/7 constant air flow for the video cards. I have two other 20 inch box fans that are for in and out airflow for fresh air circulation. All video cards are easy to access and can easily add or remove cards to/from the unit. I built the enclosure design in-house.
Serious inquiries ONLY, I have priced this as fair market price for used hardware among the enclosure costs which include the power panel, surge protection, cable runs, professional electrical hardware/electrician fees etc. This is a full plug and play type enclosure setup for any mining farm out there. Originally built for $33000~, I'm strictly selling it at a fair hardware priced value with cutting out a lot of the fee's that you would have to pay for an electrician to wire up your own custom enclosure and the electrical hardware. Cash or Bitcoins only.
Asking $15000 Canadian firm. Also I am located around Vancouver, British Columbia, Canada.

[Build Help] R9 280x benchmarks lower than 7970?

Sapphire 3dMark 280x
XFX 3dMark 7970
I bought a used 280x to sli with my 7970 off ebay and was expecting it out preform my 7970 slightly. Was disappointed when it benchmark lower. Is it slightly defective or is anything wrong or its just something that might happen?
I am NOT new to ebay even though I have no feedback. I am simply starting a new account because I am selling some things for a friend and I want to keep it separate. Thanks
What I have is a slightly used graphics card. It was used for less then one week and comes with everything including the box. They were used to bitcoin process. I have about 15 total of this model.
Sapphire Radeon R9 280X 3GB GDDR5 DVI-I/DVI-D/HDMI/DP Dual-X OC version (UEFI) PCI-Express Graphics Card
If it's a big discrepancy from what it should be, should i try to return?

Work and Play PC, Budget 1-1.2k

Filled this out almost a month ago before deciding to wait for Black Friday sales. I'm not particularly learned regarding the ins and outs of holiday deal shopping so I hope you guys can help me find some good Black Friday savings on what should be an expensive PC for me.
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
Heavy photoshop and autocad use, along with the rest of CS6 and occasional video editing, all for work. Gaming in the form of Minecraft, CS:GO, Dota, Hearthstone, Skyrim etc.
What is your maximum budget before rebates/shipping/taxes?
I can go around 1200 tops.
When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
Black Friday/Cyber Monday deals.
What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
Tower, Monitor.
Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
GA, USA. I will be going to Microcenter early next week.
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
Keyboard, Mouse, Windows 8.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
Maybe down the line, not necessary right now
Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
SSD, i7 4790k, support for HDMI on case and monitor. I will be using a Wacom Cintiq 13HD extensively.
Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
Hopefully not too big and include DVD drive.
Do you need a copy of Windows 7 or 8.1 included in the budget? If you do need one included, do you have a preference for one or the other?
No.
Extra info or particulars:
My friend has offered to re-sell me a Sapphire Radeon R9 280x he has used for bitcoin mining for very cheap (~50 bucks). Is that worth it or should I buy new?
Also, I'm trying to keep this as future-proof as I can.
Thank You!

How to fix crashes and low hash rate on my new scrypt rig?

I need help to get past two major problems in my scrypt mining machine (see my config at bottom).

1 problem is system crashes during mining, even with low hash rate

2 problem is the low hash rates. 280x running at 400 k/hs and R9 290 at 180-400 k/hs

So far I have tried mining on Windows 8.1, Litecoin BAMT Linux and SMOS Linux with much luck. On Windows 8.1 I have gone through tons of AMD Driver versions from 13.1, 13.11 beta v9.4, 14.1 beta, 13-12, and bunch of other versions. Even tried couple of DDU clean ups. I have also tried different iners like cgminer, bfgminer, etc. Note on windows 8.1 I can't see GPU temp either. However, the hangs and low hash rates persist. One of the main issues is I can't get around play around with miner settings due crashes.
On linux at least I can see GPU temps. But from my testing the system still hangs when running at 400 k/hs on my two R9 280x or 180 k/hs on R9 290. My setting for above on cgminer was (2x 280x and 1x 290 at the end):
cgminer.exe --scrypt -I 12,12,12 -shaders 2048,2048,2560 --auto-fan --target-temp 65
Here is my hardware config:
MSI Z77A-GD65 Motherboard(highly recommended on bitcoin.org board)
Intel Celeron G1620
Corsair RM 850W
G.SKILL 8 GB (4GB x 2)
Sapphire Radeon R9 280x
MSI Gaming R9 280x
XFX R9 290x R9-290A-ENFC
Anyone got any suggestions on what to try next? Seems like very hard to mine effectively, for me atleast...

Planning on building a mining rig, would appreciate if I could get some help.

First of all I can't really decide if it's better to go for a bitcoin or doge/lite rig, but my stomach tells me to go with doge so I guess that's what's gonna happen!
I'm a complete newbie when it comes to this, but I've been looking around for a while and want to give a shot. I'm planning of going with 4x XFX Radeon R9 290X, should I perhaps go for the 280X or completely another one? I can get the 290X for 615$ each and 280X for 415$ each. I'm not entirely sure for the other parts but I had a look here http://www.coinminingrigs.com/ and guess I would take something similair. I'm guessing I could get 800 kH/s out of the 290x and 700 from the 280x, does anyone have some exact numbers on how much is possible (I had a look here https://litecoin.info/Mining_hardware_comparison but getting way too confused with all the different 290's and 280's lol).
Any input is appreciated, my budget is 2500-3000 (+-150)$.
