Case: Rosewill RSV-L4500 (will custom mod it)
PCI-X reiser: 7 x USB powered via 6-pin (not SATA)
I was originally thinking about Asrock BTC motherboard and 6 XFX cards but I might as well pack maximum I can in a 4U chassis Also PSU might be a bit overkill but I want to avoid running two smaller PSUs.
It will be hosted in a proper datacentre with very good cooling (cooling alleys etc)
The Intel Celeron G1840 uses the LGA1150 socket and the MSI Z170A Gaming 7 uses LGA1151, so they aren’t compatible. You’re better off with the ASRock H81 Pro BTC or even the ASRock H97 Anniversary, as they’re both compatible with the G1840 and they’re much cheaper than the MSI board.
If you really want 7 PCIe slots, then the MSI Z97 Gaming 5 is the LGA1150 board you want, but it’s $100 more than the ASRock boards (assuming you can find them in stock). That being said, I believe 6 card rigs are actually more cost effective than 7 card rigs. The main reason is because the SuperNOVA 1600W P2 is ~$200 more expensive than the 1300W G2 model where I’m from. Together with the extra $100 on your MSI motherboard, you’re adding close to $300 to the cost of your rig, and you haven’t even bought the 7th GPU yet. So you’ll have to check local prices and do the math to see if it makes sense for you.
Everything else looks good. SSD doesn’t need to be that big, but I see that model is on sale on Newegg so that’s fine. The Rosewill case is a really nice touch, as I’ve seen some pretty sweet rigs built with those.
Oh my bad I completely missed that the Celeron got different socket
Regarding PSU will 1300W be enough got 6 gpus? I will try to undervolt them and overclock memory. Also is worth investing in platinum PSU rather then gold?
I’m running 6x RX470 on an EVGA 1000W GQ, undervolted core and OC’d mem and dual mining so 1300w for 6 480s sounds reasonable, 1200w would also work. Whether or not it is worth going platinum depends on energy cost and price gap between gold and platinum in your case. I would also recommend 4gb 470s with Elpida or Samsung ram, I am beating some 8gb 480s with my visiontek 470s (30mh/s ETH), at a lesser initial and power cost.
Comparing EVGA 1600 P2 with EVGA 1300 G2 I’ve noticed the first one got 5 x 6-pin ports only where 1300 G2 has 6 x 6-pin ports. This will leave me with max 6 GPUs which actually would make more sense cost and power usage wise.
I’m of the opinion that the higher the version number the better - so would suggest these (from your post) which are version 6C - where as the pack of 6 is version 5.
Have you set it up successfully? I remember someone said this motherboard does not support 7 GPU due to memory bandwidth, instead it only support 6 GPUs with 8G RAM.
Hi anybody!
I use MSI z170 m5 with 6 gtx1070. Runs great with 6 gpu and i think it can runs with 7 gpus, but i have issue with the upper pci-e x1 slot. Every time i connect to the upper pci a video card i have a lot of crazy behaviours of PC and it cant load OS.
I dont know what to do, because i have one more gtx1070. Should i go to this mobo seller and ask to change board. Or should i give up? )
Asus gtx1070 8gb very nice. have 420 sols/s in stock from each and 460+ with small overclocking.
Look around for the dedicated z170 topic here. I believe I read there that you need to update your BIOS to the latest (v1.7?), and that fixes the 7-GPU problem. It’s quite an elaborate thread, so take a look!
actually i remmeber a guy emailed me late last year, said he bought a truck load of those baords from MSI, said he forced MSI to make a bios for the board to accept more GPUs
I told him to push them to make the BIOS public
dont want to say i had a hand in that bios being available, but I very well might have as he didnt think he could get them to make it public… but i told him… tell MSI,… they will sell boat loads of the boards if they do so
Also PSU might be a bit overkill but I want to avoid running two smaller PSUs.
