Title: H110 Pro BTC+ Cant boot(post) with more than 8 SAME GPU(13 mixed cards are fine) Post by: menulius on November 24, 2020, 11:28:18 PM Hi,
I used my H110 for a very long time with 13 mixed GPUS. Eventually, I bought a second H110 and 13 rx 5700 xt graphics cards. I thought everything will be the same straight forward, but I faced a very strange issue. My rig does not boot (post) if I add more than 8 the same model GPUS, i.e. once add 9 rx 5700 xt, click power button there is just nothing comes up. For example, 8x rx 5700 xt = boots fine 8x rx 5700 xt + 3 rx 570 8gb = boots fine 9x rx 5700 xt = fails to boot I did try all the suggestions in a similar topic http://forum.asrock.com/forum_posts.asp?TID=6589&PN=2&title=h110-pro-btc-cannot-boot-with-more-than-9-gpu added more rams configured GPU as Parsec in the topic above suggested my CPU supports 32 PCIe lanes I did try changing all cables, risers I have 3x850W power supplies which provides more than enough power for 9 gpu Setup: H110 pro BTC+ Intel G3930 CPU 4GB Ram 500GB Sata SSD 13x RX 5700 XT 3 x Corsair RM850X PSUs (850 Watts each). Any ideas why the rig works perfectly fine and stable using 13 mixed cards or 8 same and 5 other brand cards, but it does not work once I add 9 same model cards?

Have a h110 running 11 570s and 1 560 no issue did have 12 570s but had a psu go bad and new one was short plugs so had to reduce. The 560 is just cause :) 14mhs is 14mhs. Maybe check bios..mine is H110 Pro BTC P1.10 ...
Im remote until morning i can get more specific info then if needed. (look at actual bios)....but ive got several rigs running 13 cards.....so not sure maybe something to do specific to the newer card? I will note the rigs have i5-7400 cpus in them,...but i have an old 1050ti rig of 13 that is running a G4400 pentium just fine (50% load on cpu)...if that info helps....wierd. And i have had 2 h110 show up doa....but they didnt work at all and got exchanged. Yours is working but not when over the #.... |
