OTOY Forums

I cannot get my system to boot with GPU risers. All GPUs work plugged into mobo. I can get up to 3 GPUs working in windows with risers but beyond that windows runs into a "WHEA uncorrectable error" when booting. BIOS passes most times. I have tried different types of risers, first x16 to x16 and I am now using 1x to 16x powered risers. I have enabled above 4G decoding in BIOS and am doing a full UEFI boot.

Risers themself does not do anything bad it's not soemthign system sees, but..if You them, use god, short quality pieces with good contacts & propper shielding =) check this piece we wrote with Guy from Polder Animation http://tomglimps.com/custom-pc-for-otoy ... animation/

Thanks for the link, my x16 risers were shielded, the x1 to x16 risers are just USB cables…I've fiddled with this thing for hours to no avail.

have You tried powered pieces? I gues if You're running 4x GPUs anyway You're conected via x8, not x16 =)

Yes my 1x to 16x risers are powered

I had similar trouble. I just kept trying different combinations of cards in different slots, and keeping clear hand written records of what I did. A crucial step was completely resetting the bios every time I tried different cards in different places. My motherboard seemed to have preferences for certain slots. Still don't understand it, just trial and error.

I had the same problems with USB3 risers. In the end I got a single 3 way splitter. I have not had a single issue since.

I'm using that amfeltec splitter also. Has worked well.

One problem with the splitter is that it confuses Adobe CC GPU accelerated stuff. If I use GPU acceleration in Media Encoder or Premiere Pro, it gives me a hard Windows 10 crash. Anybody else seeing that?

That would be problematic…Ai etc is very slow without GPU acceleration. How much do these splitters cost? All I can find on the website is to get a quote.
