11 x GTX 970 System - john38 - 06-11-2016 hi all! like to know what you guys think about the following configuration. MB-X9DRXFB = https://superbiiz.com/detail.php?name=MB-X9DRXFB 2x Xeon E5-2620V3, 2.4 GHz Six-core 11 x GeForce GTX 970 32gb RAM kingston 2x 1500 watt power supplies and daisy chain them safely with a little module 11x PCI-Express PCI-E 16X Risers 120g ssd kingston hyperx ubuntu 14.04 LTS frame would be some ALUMINUM similar to this one: let me know what you guys think RE: 11 x GTX 970 System - radix - 06-11-2016 Historically, there has been a 8 card limit due to non 64bit BIOS support, so that may be an issue. I would contact SuperMicro and confirm you will not run into that issue. Otherwise, should be fine with everything else.

RE: 11 x GTX 970 System - atom - 06-11-2016 also note that with 8 gpus you will have 8x 100% cpu load because of shitty nvidia opencl runtime. make sure you have enough cpu power RE: 11 x GTX 970 System - kiara - 06-12-2016 (06-11-2016, 10:57 PM)john38 Wrote: hi all! like to know what you guys think about the following configuration. are u not afraid of it to get really hot for the cards? it does not look like the cards will have lots of space between them.

Might be helpful to double check especially if you have other stuff running through PCI. RE: 11 x GTX 970 System - kamsulla - 07-14-2016 I checked my system (1cpu xeon, 2 x gtx1080), I took the card1 x16 slot and second card is x8 slot then check the benhmark same speed ~417kh ~414kh.
