I have a gigabyte GA-990FXA-UD3 R5 and is running 2 graphic cards on the board in the pcies x16 The mobo has 4 pcies 16x and 2 pcies x1 ... When i try to add a usb x1 pcie riser the pc does not work ,,, Windows 8.1 recognize the usb X1 to X16 pcie riser but when you plug a gpu on the riser is not working ,,,, also i tried the trick with the cable A1, B17 ... https://bitcointalk.org/index.php?topic=36061.120 and it got stuck the bios and i had to remove the mobo battery for a while .. Also when I place the usb X1 riser in a motherboard X16 pcie slot again is not working ..... should i try risers with flat cable ? 16x to 16x and 1x to 16x ? If you have any suggestion let me know ....

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

As for AMD, in 8/8.1 if you installed Microsoft driver(from auto-update) not AMD(downloaded from amd.com etc) - then more cards were working. Basically M$ driver had my mod embedded ; ) But not all of it. In w10.. imo a lot of things have changed. Also AMD removed Catalyst. Actually, the whole idea of the mod grew from this post - https://bitcointalk.org/index.php?topic=193695.msg2536323#msg2536323Anyway, there were no limits hardcoded or stuff like this - just the driver and it's configuration were not tested properly on 6+ GPU setups. Imo since nVidia launched Grid, they did test on 'a lot of GPUs' systems and AMD didn't. In the Windows 8/8.1, the auto update driver, which version is that? Is that version good for Ethereum mining?

If you have any suggestion let me know .... I'm running 1x7950+5x290 on 990fxa-ud3 R3 right now. I was running 6x290 on it also. Using x16_x1 powered risers(flat). Without PCIe precence short(A1, B17). Motherboard is picky about primary GPU - the monitor must be attached to the GPU selected in BIOS. Also to run headless "full screen logo show" must be enabled in BIOS. And try setting PCIe to 1.1 speed in BIOS.

Hm. Looks that way. Or m$ screwed somewhere ; ) Also, you can find driver version using GPU-Z.

4x7990 max. afaik. That is 8xGPU. Use Windows 10. As for x16_x16 vs x16_x1.. well.. I dunno. I've tried x16_x16 risers also and they did work. However I've never used x16_x16 in production, that is running rigs 24/365. Only x16_x1. Anyway, your issues.. seem weird. Technically there is no difference between usb risers and common x16_x1 powered risers. However, I've seen vide cards which just refuse to work with any riser. And.. since I can't get hands on your system.. sadly I can't help.. But do try setting pcie to 1.1 speed(I can't find it in the manual.. maybe it does not exist?), setting primary GPU to one of the x16 slots and plug GPU there. Only one GPU. Play with those - Manual, page 47 Init Display First Specifies the first initiation of the monitor display from the PCI Express or PCI graphics cards . PCIe 1 Slot Sets the graphics card on the PCIEX16_1 slot as the first display. (Default) PCIe 2 Slot Sets the graphics card on the PCIEX16_2 slot as the first display. PCIe 3 Slot Sets the graphics card on the PCIEX4_1slot as the first display. PCIe 4 Slot Sets the graphics card on the PCIEX4_2 slot as the first display. Manual, page 45 Full Screen LOGO Show Allows you to determine whether to display the GIGABYTE Logo at system startup. Disabled skips the GIGABYTE Logo when the system starts up.

It is very ordinary riser cable. Two with molex +12V power, two without. The 7990 draw very little from the PCIE and I undervolt and underclock them.

Probably cause 4x7990 have less video available display connections than 8x7970. But I cannot use 6x390 on the Asrock H61 Probtc boards. Anybody with any luck on that MB?
Even with the mod?

I've tested it with 16.1.1 and 15.12 Does it work on 7 or 8 GPU? For example we would like 2X7990 + 4X390 or 3X7990+2X390. I cannot make it work on ASrock H61 Pro BTC with 6x390. Maybe it is just the MB.

You need to run it as administrator
