Title: 12 GPU rig... but how??? Post by: SealTx on June 02, 2017, 05:46:02 PM In this discussion: https://bitcointalk.org/index.php?topic=1541084.msg19319534#msg19319534
There is an example and a tiny bit of talk about a rig that controls 12 GPUs The idea is that the builder uses PCIe Switches (https://www.ebay.com/i/371913923974?chn=ps&dispItem=1) for 9 of the cards and the other three are on board: Using common MSI Z270-A Pro + Celeron G3900 + 4GB RAM +3 x PCI-E Switches (9 GPU's connected to switch and 3 GPU direct to motherboard). Power Subsystem - two HP common slot PSU 1200W + 160W Pico PSU (for motherboard and switches) Sorry for bad photo and my English) http://i.piccy.info/i9/8ec902e393a819cd6e28da0c657ce61b/1496350066/143938/1150706/_A5855D8E973CE290DECE4AFFBDA4CD5B935F4D51AF5C4080C2_pimgpsh_fullsize_distr.jpg Does anyone have experience making the CPU / bios / whatever to detect 12... or maybe 18 GPU's? TIA! Title: Re: 12 GPU rig... but how???

Somewhere read that with 12+ gpu in single motherboard you'll have troubles, but i make rackmount frame for rig and there 12 gpu optimal. At next week want to test 4 PCI-E switches in old motherboard (HP Pro 3130)There is an example and a tiny bit of talk about a rig that controls 12 GPUs The idea is that the builder uses PCIe Switches (https://www.ebay.com/i/371913923974?chn=ps&dispItem=1) for 9 of the cards and the other three are on board: Using common MSI Z270-A Pro + Celeron G3900 + 4GB RAM +3 x PCI-E Switches (9 GPU's connected to switch and 3 GPU direct to motherboard).

@NotFuzzyWarm sry... wrong board. Maybe a mod can move the thread? Thanks! Title: Re: 12 GPU rig... but how??? Post by: dimka890 on June 02, 2017, 11:02:31 PM @dimka890 Thanks! I will try with a bunch of 1070's I have on the way. Some chinese sellers say that switches does not work with Nvidia GPUs, but if you can test it will be good. Unfortunatly i don't have any nvidia cards.@NotFuzzyWarm sry... wrong board. Maybe a mod can move the thread? Thanks! P.S. I saw at aliexpress switches 1-> 4 PCI-E, there is no mention of nvidia cards, maybe 1-> 4 switch will be work fine Title: Re: 12 GPU rig... but how???

Nvidia is all I can buy at the moment. I will tell you what I discover ;) Title: Re: 12 GPU rig... but how??? Post by: Vaccinus on June 03, 2017, 05:43:58 AM wait for asrock h110 pro btc come with supported 13 gpu slot, you just plug and play, no mod no anything to do, they are still tweakign it, still brand new motherboard, cost $150 or so

And m2->pcie for 9 nvidia gpu on asus prime z270a For 13 and more gpu remeber if you have problem with 1gpu - you have problem with all gpu on rig Sorry for english. Title: Re: 12 GPU rig... but how??? Post by: dimka890 on June 03, 2017, 02:39:26 PM Please write here feedback about 1-4 switches, it's very interest.
P.S. Where you are frome? Title: Re: 12 GPU rig... but how??? Post by: realter on June 03, 2017, 08:49:41 PM Please write here feedback about 1-4 switches, it's very interest. Russia, TogliattiP.S.

Post by: QuintLeo on June 04, 2017, 12:33:23 PM Yes, riser-rig miners, ASRock has heard your complaints about the shortage of H81 (keep in mind that when Intel stops making a chipset, board makers CAN'T make more of the boards using that chipset once they run out of stock of that chipset) and has a MONSTER of a replacement/upgrade that is apparently fairly close to release.
They DO need to figure out and fix whatever caused their demo to crash and burn first, though - perhaps add 1 or 2 more MOLEX to the MB for PCI-E slot power I'd guess.... There is already a longish thread specifically about the H110 BTC Pro though.... |
