I want to know Which cpu will be better for my rig ? Best Psu for 6 Rx 470 cards ? Type of best power Riser molex or sata connectors ? I have sata and 6 pin connector Risers How to setup 1x to 4x expander card? On 1x slot or on 16 x slot ? Any more I have to modify motherboard bios ?can I mount more than 6 gpu on asrock h81 r2.0 using 1x to 4x pcie expander card ? Do I will face any problem using Pentium for 6 or more GPUs ?

Use the cheapest 4th gen CPU you can find (Socket 1150 is all that matters). Don't know about best PSU, but 1200+w 80 Plus Gold should be ok (modded server PSUs are also nice things, can be a bit loud tho). You really cannot get "the best powered risers", always order a couple more than you really need. Please stay away from SATA risers, things can get hot. MOLEX is better and 6-pin PCIE is the best. From BIOS change PCI Express to GEN 1 and "Restart PC after power loss". Have seen a couple of photos people running 7 GPUs from this board, never have tried that myself. Pentium is fine.

If you do not mine using cpu then any cpu would be good enough so choose the one that consumes less power.

hi, Guys! It is Great News! Windows Update on Jan/3/2018[KB4056892] might fix this probrem! You no longer need HackFlags nor Disable Audio Devices! Hi. You sir solved a lot of headaches I had with that asrock code 12 issue. Me and my customers thank you very much. Give me your btc adress, I'll send you 0.0025 btc as a tip.

Just had a reply from ASRock Support:
Hello, 1. Please try to borrow more RAM to test with. 2. Try increasing virtual memory in Windows to at least 16GB. 3. The Molex power connectors on the motherboard must be used, even with powered risers. I know you tried this already. 4. Please try to test with Windows 10 version 1703. Any change? Kind regards, ASRock Support
Trying this now
I don't care what asrock support says, the molex power connectors aren't to be used UNLESS you are using Unpowered risers, not powered risers. I have both the older version of the h81 and the newer r2.0 neither of which do I power the molex on the motherboards and they work as intended

After lots of troubleshoot now all is also working good. Microsoft Windows 10 1703 did resolve all problems !!! Only message this board give at start: please install the psu's 4-pin power cables to the 4-pin power connector on your motherboard While all cables are connected, and the rise cards and GPU has power directely from my 1200 watts unit. Is this something to worry about ? Are is the board only telling you , that you have 3 cards or more it does say you can ignore the message too, and yeah it only pops up after connecting certain amount of gpus. once ya tell it to ignore the message it doesn't come back

Hi everyone, it worked for me HackFlags. My mining is running 5 gpu perfectly. Here's my setup: Asrock H81 Pro Btc R2.0 Celeron G1840 5 Gpu Gtx 1060 3gb 4gb ddr3 Windows 7 Ultimate SP1 64bit I did not need to update the bios, just install the drivers with nvidia 382.53. Important, connected with the video onboard, and disabled on the audio bios onboard and disabled in the device manager all the audios of the gpu.

I have both the older version of the h81 and the newer r2.0 neither of which do I power the molex on the motherboards and they work as intended I have only one of these boards - and i't been up and running for 4 months. I am running Windows 7 and 6 1070ti on it. I'm using powered, Mintcell risers and found it doesn't matter if you plug the Molex cable into the MB or not. Works fine either way. I'm not sure why you think you shouldn't use it. I actually have it plugged in right now. I don't think it matters - no harm with or without. But I am interested to hear why it should NOT be plugged in or are you saying it doesn't matter if it is or isn't? Thanks

Hello Friends
What is Hashflag how to use it ?
"Hashflag"? - That is the use of a small graphic and a Twitter hash tag together. Personally, not a fan of the use of them. But... "Hackflag" is describe on this thread (just page back one page) - it's used to change / modify Window's registry when you run out of Peripheral Component Interconnect (PCI) bus numbers. Just be careful when you mess around in the registry. Read up on it before changing anything. Good luck,

Yes, Windows 10 , version 1709, Jan 2018 Cumulative Update. I had nothing but problems with 1709 on the H81. Had to reinstall 1703 to overcome code 12 DMA conflicts. Maybe I'll take a system snapshot and try updating again - don't like running all this unsigned code on an unpatched OS.

After days of debug i found the solution with this motherboard. Drop Windows 10 with this board and install Windows 7. All your GPU will be recognised in no time.
Forget about windows 10. Not to mention i have better performance with windows 7.

A noticable hash rate difference in all your GPUs? What percentage increase did you see with w7?

I'm getting about 8000 on win10 with 6x1070ti, but had to disable some CPU-intensive stuff to get there.
