You can purchase windows 10 and license online for 35.00. I purchased win 10 from a newegg vendor for 37.00 a while back.

UPDATE

     I'm a bit late to the party, but I'm getting 260-267 h/s on 10 Sapphire Nitro+ rx 480 OC 8gb cards totaling 2580 - 2610 h/s (stock bios). According to GPU-Z, each card draws an average of 115w (core), but shows intermittent spikes no greater than the maximum specified power consumption for the card (225w). Running Windows 10 on both rigs with crimson V. 16.11.5 (this is the most recent update, that I've found, that will recognize a bios mod).

     I could do 8 cards on the MSI Gaming 5 (7x PCI-e + 1x M.2 ---> PCI-e adapter), but the rig lost some stability once I went over 6x GPUs, even with enough power. The Gigabyte ga-z97x Gaming 7 can house 7 cards (6x PCI-e + 1x M.2 ---> PCI-e adapter), but as I said before, stability seemed to become more of an issue with more than 6x GPUs. Each rig has been running for about a week without any resets or crashes. Just in case the miner or machine does crash, I have made some simple .bash scripts to restore all of my settings and programs upon reset. I have also used the Windows Event Log and Manager to reset in the event of a freeze crash. So all in all, I plan to have 6 cards per rig and I'll probably have to add another PSU to the first rig when I reach that point.


*DAS IMPORTANT*

     When it comes to power supplies, it is almost ALWAYS cheaper to buy 2x units and an adapter, than it is to shell out the money for even a 1200w PSU. My EVGA Supernova P2 1200w Platinum was about $220 (on sale), but I could have bought 2x  700w-850w PSUs + a convergence adapter for 2/3 the price. Also, Never purchase a PSU with a rating less than gold; it will save you both time and money in the long run.

*This is a great PSU reference guide. https://i.imgur.com/tgrbCnr.jpg

     On a final note, I am aware that there are mods to allow for more than 4 GPUs on Windows 7 and more than 5 GPUs on Windows 8, but save yourself from a giant, time consuming pain in the d!

Actually i will be more interested in the Motherboard used for 8 GPU and how to set it up .

MSI Z97 Gaming 5 with an M.2 to PCI-e adapter.

1150/1900 obviously custom bios undervolted etc. Still pulls 890 at the wall, but the point of my post is as long as you know how to balance rails and tune everything right there is no reason you can't run a PSU at its max capacity.

u can also just type manual eg..

http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows 7 - 64&rev=14.12
goes to 14.12 just change to whatever os and change to whatever driver


http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows 10 - 64$rev=16.9.2
http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows 10 - 64$rev=16.9.2
goes to 16.9.2 win 10

that doesnt work anymore they changed it
here is a list back to 15 http://support.amd.com/en-us/download/desktop/previous?os=Windows%207%20-%2064

very easily
http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-Software-Crimson-Edition-16-3-2.aspx

that doesnt matter when u run a modded ram timings as what is done is the timings used on lower clocks are set to the higher giving u better speed at higher clocks than norm but can also reduced total speed u could do before on stock bios like ram on a pc if u set tight timings u wont oc as much

I have it running stable at 1110/1440 @80C. will be buying the ARCTIC Accelero Xtreme III cooler. They say it helps both with the temp and mostly noise. Staying at a hotel and the noise is really a problem lol

from the above u have elpida ram which is slower than hynix just use the bios from the modded thread from here https://bitcointalksearch.org/topic/hacked-modified-memory-strap-bios-database-for-zec-mining-1676474 since u have a ref like u said scrol to the bottom and use those set clocks to whatever keeps the temp 75c or lower and mem to 1450 depending on how good those elpidas r u might get a stable 1475 on the ram

they didnt have faster ram it was just clocked higher it comes down to if u have elpida or hynix only diff besides that is the 390x stock has 8gb and fewer components cause the chips run more eff cause its a later spin of the same die just they fine tuned the process besides that they are = in speed clock 4 clock

Anyone use claymore with Miningrigrentals?

 Keep in mind that the top-end 3xx (and 2xx) cards have 384 bit (280x/380x not sure on the 280/380 non-X) or even 512 bit (290/390 AND UP) wide memory access, which makes their somewhat slower memory clocks give significantly more memory bandwidth than the 256 bit wide memory on the RX 470/480.
 This isn't as critical on ZEC which doesn't appear to be as memory-hard as ETH, but it still matters.

 Core clock speeds on the 4xx also didn't increase all that much over the high-end 2xx/3xx series cards - AMD seems to have aimed more at dropping power consumption with VERY good success on these MAINSTREAM cards - while the core count on the RX 470 is the SAME as the R9 280x/380x (2048) and the RX 480 has FEWER cores (2304) than the R9 290/390 (2560) or the 290x/390x (2816).

 Expecting the RX 480 MAINSTREAM card to OUTperform the one generation old top-of-the-line R9 390X is just WRONG, given the actual specs on the cards - the clockrate improvement isn't enough to outweight the lower core count, and the memory bandwidth just isn't there at all comparatively.

 Keep in mind that AMD started near the MIDpoint on performance (and a much lower price point) on their new generation - until they release a potential RX 490 or higher, the older cards are going to remain the performance champs (at the cost of HUGE electric usage).

 This is actually some bad news for NVidia, as the midrange AMDs are arguing pretty well against higher-end NVidia cards at a much lower price point for MOST usage....

 That was a very few very early R9 290 units that were actually R9 290X GPUs with the extra CUs locked in the BIOS.

 The R9 390X and R9 290X used the same GPU, but the newer card had BIOS updates and faster RAM (and sometimes more ram).
 There should be cases where a 390X BIOS will work on a 290X, particularly if it's the same manufacturer and same "model", but there is no guarentee.

Hey Claymore and gang.  I've got a funky one for you...

(tl:dr? Go to the bottom for update.)

So I just cobbled together this 4 card rig.  Previously I had all these parts running in a case with 2 7950 cards, one Sapphire and one XFX.  I put together an open-air rig and risers using the same hardware that was in the case (MB, Memory, proc), and added a pair of MSI 7950's, for a total of 4 cards.  I daisy chained a 500W to the 1000W power supply and have the 500W powering the MB, three 120mm fans to move air across the cards, a 1TB conventional HD, and 1 card.  The 1000W is running three cards.  I am not at my rig at the moment so I don't know which card is running off the 500W supply (this I admit might become important).  Fresh Win 7 install, 15.12 drivers, GPU-Z and HWMonitor, Teamviewer and nothing else.  After fighting with Windows and finally getting everything talking to each other I ran some spot tests for power draw and stability.  Everything looked good.  Started v11.0 miner and ran it for about an hour this morning and found that with my previous settings I used in v9.2 I was getting around 225 from the Sapphire, 220 to 230 from the MSI twins, and about 215 to 220 from the XFX.  I also discovered that one of the fans was vibrating about its shaft and generally being a pain in the ass.  I removed it and attempted to lube it but that wasn't its problem.  That being said, it still provided adequate cooling as indicated by GPU-Z telemetry.

About 15 minutes before I left to go to work I fired it all up and put it to work, walking out the door around 1pm.  According to the logs, temps across all the cards were steady around 62C to 65C (-tt set to 65) with fans ranging from 55% for the XFX to 40% (the baseline min) for the Sapphire.  About 25 minutes into the run the logs show the fans on the XFX ramping up to around 75%, but the temps were steady around 65C.  Seems the fan is starting to act up again.  Anyway, shortly after this I see the GPU temp fall rapidly and about 3 minutes later the watchdog found it unresponsive and commanded a restart. 

When it came back up it seemed to initialize fine but now it's running about 100 sols/s slower than the other three cards, at around 105 to 125 sols/s.  Looking at GPU-Z, the thermal and voltage readings are inline with a card at 100% duty cycle just like its brothers, but it's doing half the work.  Logs don't show anything extraordinarily funky except for one thing: when the watchdog ran a minute after the restart it showed:

"warning: solutions buf overflow, 1928276 > 24"

In the log prior to this was the speed check which showed the XFX running at 120 sols/s.

A few observations I hope might help.

I am not at the rig.  I am elsewhere monitoring it, so I apologize for not giving log snippets or screenshots.

All cards have stock BIOS.

All cards are normalized at 950/1350.  The XFX is based at 800/1250 but has been running at 950/1350 for months with zero issues.

All voltages are stock.

All cards are on risers (USB/powered).

The XFX card's riser is in the 16X slot and is driving the monitor.

The XFX is rock solid and happily hashing out 125 to 135 sols/s with no apparent failures. Telemetry suggests it's working as hard as the other cards.

I am not getting any rejected shares, neither prior to nor after the incident.

I can neither confirm nor deny that the XFX is the sole card connected to the 500W supply at the moment (aforementioned proximity to rig).

The 500W supply was not in the system when it was in the case running two cards. I removed it and installed a 1000W supply when I added the second card.

The 1000W supply is a single 12V rail supply.

The card hashes about 435 h/s using Claymore's Cryptonote 9.7 miner, while its brothers push out around 480 h/s. Oddly, the XFX is doing this using 37% GPU load, where the others are at 68%. O.o  Telemetry suggests this is true.

The card is deficient running v9.2 of the Zec miner.  It didn't have this problem with the same settings prior to transplant.  All cards are hashing around 180 sols/s except for the XFX (125 sols/s)

The tests show you are not the father.

So, whadda ya brains think? 

EDIT: Well, it looks like this card is lagging across the board, so it's certainly a hardware problem, and I'm suspicious that it's a power problem.  To that end, how much power do these kind of cards pull from the motherboard?

EDIT 2: Nevermind. 75W for PCIex16, 25W for PCIeX1.  I'm assuming that all cards are pulling 25 watts out of the board, thus 100W I didn't account for coming out of the 500W supply.  Hmmm...

I have the error with the program Claymore Miner v11.0 Beta
GPU0 t = 72C fan = 100%
ZEC: 01/14 / 17-20: 14: 51 - SHARE FOUND - (GPU 0)
GPU # 0 returned incorrect data! B508d064
ZEC: Share rejected (1750 ms)!
¿Does anyone know what to do with this error? I do not have much idea to do about it, because I tried installing it on other computers with the same result, it is a 480 4gb rx and it is mining alone, help 

mine is the powercolor first reference with 4 gig. Can I still do it?

yes as they are the same just 390x comes stock with 8gb ram and a bit better power optimizations and higher default clocks
but yes u can use either or bios depending on card pcb and there are 8gb 290x's

1150/1900 obviously custom bios undervolted etc. Still pulls 890 at the wall, but the point of my post is as long as you know how to balance rails and tune everything right there is no reason you can't run a PSU at its max capacity.

correct, just run the cuinfo. just investigating if the 290x can run as a 390x as is claimed
