Guys, Does anyone know if you are able to run 12x rx580 or 12xgtx1070 in windows with claymore without issues?
I know that ati released new drivers that would allow you to do this for rx580, but I am not sure, and certainly not sure about nvidia.
I am right now using h110 pro btc, but planning on getting b250 mining expert motherboard if that help.

Guys i am banging my head against the wall with this issue.

I have h110 btc pro with 12 gpu, 6 ati and 6 nvidia, windows 10.

I really want to mine all cards in 1 instance but system freezes up when i do that.

Current solution is to have 3 instanses, First one for 3 ati, Second one for the other 3 ati, and third one for 6 nvidia.

Btw, i cant run 2 instances with only ati. As soon as i have more then 3 ati in 1 instance it freezes up. I could do 2 instanses with 6nvidia+3ati and 3 ati in the other one.

Is this a claymore issue that i cant run all cards in 1 instance? or more then 3 ati in 1 instance?

Another issue is that my disk is slooooowly running low. I have tried to clear everything I can but somehow something its ups all space after a while.

Any tips?

No i dont have any splitters, for 6 cards i use 6 pci-e Cables, 4 of them have 1x8 pin and 2 of them have 2x 8 pin.(i leave the other 1x8pin), my cards only takes 1x8pin anyway.

I have read alot about my gtx 1070 with micron memory that it will crash sometimes when it goes from idle voltage to full load voltage.
Solution was to set "prefer maximum performance" or to lock the voltage above 0.811v for each card.
Been running now for 2 hours but really dont have any idea if this is the solution.
Anyone else know about this?

Connected my 6 risers with molex directly from psu, 2 risers per molex Cable.

Ok I just got some new information regarding my problem getting "cannot get target temperature, error 15/999"

I tried ethOS and same thing happened there, i guess that rules out any os/graphic drivers issues because my friend have the exact same rig and it worked flawlessly in ethos.

I have swapped the usb risers as well with no success.
The only thing i can Think of is my PSU now, when all 6 cards are at 100% Power , around 900 watt, it almost instant.
But if i turn it down to 65%, the whole rig takes 650w from wall, it runs without crashing.

I am using molex directly from psu to Power up to 2 usb risers per Cable, instead of doing the sata to molex convertion.
My psu is ax1200i. Can I use the corsair link to somehow see if there is any problem with the psu or maybe change something there that could help me?

All these crashing is btw even with stock setting, no oc at all.

What do you guys Think?

It is only 1x8 pin on my cards.
What I meant by my question is that some of my pci-e Cables have 2x8 pins and I have used these Cables to connect 2 cards in 1 Cable.
So thats 2 cards powered up with 1 pci-e Cable. Could this be a problem? Should i only use 1 Cable for 1 card instead?

Guys, dumb question.....

I got 6 x gtx 1070, 4 cards are powered with 2 pci-e Cables that have 2x8 pin each, and 2 cards are powered using single Cables with 1x8pin.
I guess my question is, is there any Power difference/problems if you connect more than 1 Graphics card with 1 single pci-e Cable?

I will try this and get back to you, but this is now weird.

Havent changed anything but some oc in afterburner, 75% Power, 85 temp, -400 core, +400 mem and its been running for 16 hours.
Tried this as well yesterday with a Little modifications and its jsut crashed after a while.

Checking in afterburner, it usually crash when the % Power make a down spike or drop, does anyone know why this happens? Do I need to add more voltage or Power to remove the spikes? Because i guess thats what causes the instability.
Also, spikes usually happens when i get a new job in claymore, maybe it should be like that.

Uploaded image of it, usually its the last gpu that fails. http://imgur.com/a/fJTTt

Edit : In my Control panel, Power management is set to optimal Power by default, is it best to have that or maximum performance?

I didnt even know 372.54 was recommended, thats why i am asking. Just want to know what most people use for these cards.

Do you guys recommend any specific drivers for 6xgtx1070 mining ethereum with claymore?
Using latest drivers but getting "error cannot read temperature".
Seen some people recommend 382.53 and 382.33, while the miner says to use Another version.

its off, just checked it again.
What could it possible be? Can this scenario cause any problems:
I have asrock h81 pro btc, , i have plugged in the monitor to the 16x slot, that cant be it right?
When i added the cards, i just added them all and then installed drivers. All cards are shown in device manager.
Anyone recommend doing a Clean with DDU, then starting with 1 card on the 16x or the closest pcie from the cpu, installting nvidia drivers and then adding 1 card and rebooting?
Cant really Think this is the problem but i am desperate...

I noticed just Before the "cannot get current temperature, error 999" ( and 1 cards shuts down ), i see a small windows loading circle.

Anone knows anything to disable in windows 10 that can be the cause of these crashes? I have already disabled windows update.

Is it enough having windows 10 anniversary update or do you have to get creators update for it work?

Swapped out "sata to molex" to directly molex from psu but still no success, still keeps crashing with "cannot get target temprature"

Does anyone have Asrock h81 btc pro ?
i have connected the 2 molex Cables on the motherboard aswell as having powered risers (sata to molex ).
Is this correct or should i remove the 2 molex on the motherboard?

Ok good info, i will try that.
Just to clarify, is it better to run each card alone for 30 mins or do you Think i should start with 1 card and every 30 min I add Another card, for testing.

Do you recommend getting a better psu or does changing to Ubuntu do any difference regarding the Power? Cant imagine that.
But my wattman says 950 when they are all on 100% Power target, that is for the whole rig...

I am so desperate that I will donate eth if i solve this....

6x 1070, asrock h81 btc, win 10, latest nvidia drivers, claymore 9.6, 1200w PSU, Virtual set to 16 gb.
Even at stock settings , the miner crashes, sometimes directly , and sometimes after 1-2 hours.
I have tried different nvidia drivers, and even tried previous claymore versions.
Tried swapping the cards around and setting in bios gen1/gen2 ( it should work out of the box )
I have connected the 2 molex connectors on the mobo and also having 6 powered usb risers.
Only time i can get it to go a bit longer is if i have it at stock, but change the Power target to around 60% for all cards.
I have a "wattman" and it says computer is taking 650w from the wall. but thats with low Power target, otherwise it is around 900.
When it crashes, 1 card Always dissapears , both from the miner and from Afterburner ( in AB its there but cant change anything because its grayed out ) resulting in having to reset PC.
Sometimes when it crashes , my monitor that is connected to 1 of the cards also shuts down.
Most of the times i get BSOD after the crash and if that doesnt happen, the whole computer freezes up.
I really want to Think there is enough Power to drive this with 1200w.


Edit : Just Before it crashes, my mouse curser is almost unmovable. Really laggy. But both cpu and memory are far from maxed out.
My cards temp are also not capping, just around 60.

Any ideas ?
