Title: question on multi gpu with asus z87 pro v edition Post by: racebum on April 16, 2018, 07:08:08 AM quick question on multi gpu setups. haven't had to do this one yet and am curious if anyone knows the GPU limit. if not no biggie, i can find out. second question is with risers. can i use an unpowered 16x ribbon from 16x-1 to the gpu then 4 powered risers from the 1x slots to make a 5 card gpu rig? haven't found jack online about this board and have one on the way from an RMA'd system and a spare 4790 chip
couple potentially relevant specs about it Multi-GPU Support Supports NVIDIA® Quad-GPU SLI™ Technology Supports AMD Quad-GPU CrossFireX™ Technology Supports AMD 3-Way CrossFireX™ Technology Expansion Slots 2 x PCIe 3.0/2.0 x16 (x16 or dual x8) 1 x PCIe 2.0 x16 (x4 mode) 4 x PCIe 2.0 x1 https://www.pcper.com/files/imagecache/article_max_width/review/2013-06-10/02-2D_0.jpg Title: Re: question on multi gpu with asus z87 pro v edition Post by: swogerino on April 16, 2018, 08:03:40 AM I have tried the z97 chipset from Asus and up to 6 cards works great, I don't know if you can put 7 in here as it has room and slots for seven.
For the risers use 009s Title: Re: question on multi gpu with asus z87 pro v edition Post by: racebum on April 17, 2018, 11:35:34 PM I have tried the z97 chipset from Asus and up to 6 cards works great, I don't know if you can put 7 in here as it has room and slots for seven. For the risers use 009s sweet, thank you. i did exactly that and ordered the newest ubit 009 riser. not sure if that led is really worth anything to have but it seemed cool. i have 5x1070s right now so if 6 is possible that's even better.

though I did not try them on 6 or 7 GPU due to PSU limitation 850W Title: Re: question on multi gpu with asus z87 pro v edition Post by: racebum on April 18, 2018, 06:55:16 AM I have this Board, it rocks for a year with 5 GPU, I discourage you to use ribbon type risers as it gets power from your mother board and burn it, use powered USB riser instead. though I did not try them on 6 or 7 GPU due to PSU limitation 850W oh i was only going to use a single 16x ribbon for the 16x socket. definitely aware you really don't want to run more than 2 cards on the board directly 24-7 for that very reason. other 4 cards are going to be on 009 risers from the 1x slots. do you guys usually use like one cable per two 1x riser cards via molex? i've seen posts of some people trying a 1x riser in the 16x slot but they also often complain of issues and a loose fit. my only concern is enabling the 16x at 16x may run me short on pci-e lanes. i can't find anyone who makes a 16x plug for the board that goes to a standard powered riser hmm. do you think i'm better off just trying to secure a 1x powered riser into the 16x slot along with the 1x slots now you have me thinking about pcie lanes i have a seasonic prime platinum 1000w for power. was going to check the wattage and see what i get with 5x1070 + the 4790 cpu. not sure if i can really push for a 6th card without going over 80% rated power. would like to say at 60-70% |
