I think you'll might be missing a trick here..  Should be able to load the whole thing with Nvidia's, plus some!  You just have to do it in the right order. load in numbers that wont trip the switch from x2, x4, x8, x16...    This means you should load just x1 card per section, then x3 card, x7 cards.. So you don't swicth it's limits (if this section has x4 then that section limits to x8,x4,x2 or x1)  once completed x3 cards in each section, the empty slots can be filled without limiting the others, because it can't limit to x2 with x3 in use) Something like that anyway   Think CPU lanes too

Official statement about this bios update are very clear, and they would probably say something about unlocking additional slots for non mining GPUs because that would be major change.

• 1. Update CPU Microcode
• 2. Improve system security and stability

I tested all the recent drivers on windows 10, for me blockchain driver is so far best. Here are reasons

1) For new drivers, you gotta change GPU workload to "compute" mode for each GPU. In case of rig crashes for some reason, all settings go back to default, time confusing process to change settings back

2) the main problem is the blue screen, new drivers are not stable and cause a lot of blue screen issues in my rig of 13 GPUs

3) new drivers break claymore temp and fan monitor, can't OC via claymore

Ok, I stopped at the beginning...

Where I have to put the power on off switch/jumper ?, there is nothing written in the manual about that. are the third/fourth on the second row ?

Second question:
I plugged one psu to the EATXPWR_A

I MUST PLUG ALL 3 AUXPWR_A1 and _A2_ and A3 even if I am not using more than 12 card or I have to leave the last one A3 empty ?

 

I need a little help guys. I have one AMD card (will be adding more) to my 7 card Nidvia rig. I only want to use Claymore for the AMD card. This is my bat file, but it's still running all the cards. Can someone tell me what I need to do to tweak it?

@Claymore - Your auto DCRI settings can't seem to get my RX 550 4GB cards right... It picks 13-15 per card... However 9 is best in my particular case.

so the latest drivers include the blockchain fix using compute feature? do you have a link to this?

windows decides to install some amd drivers several times now and do not want to go the uninstall/install saga again if the latest drivers are good.
Thx

Glad to here about the fix. I didn't know a Core i3 6100 is a slow CPU. I guess we need Core i7 to with 12+ GPU's in Windows.
