@Tbar,

Congratulations on the upgrade to 7 gtx 1070's out of 14 gpus.

Its really smoking along!

Yes, those last Two 1070s seem to have pushed it up a bit. I could swap out another Three 1070s, but, I think I'll just leave it as it is. Unless, someone wants to send me say 14 RTX 2080s, and a few large power supplies. All in all, not bad for a $64 Motherboard, $200 Processor, and three mid-range power supplies. You can do quite a bit for SETI on a small budget. Not much up front, and add GPUs as you go. I have the machine with the $33 Motherboard up and running 8 GPUs with the identical $200 Processor. I seem to have hit the Thermal limit for the case though, if I add the 9th GPU the temps are too much for the fans, and stronger fans are much noisier. I built the second machine just to run the older GPUs I've accumulated over the years. So far the only problem is the BioStar board has some conflict with one of the GTX 950s, whereas, the ASUS board didn't like one of the 1050s. Both GPUs work fine in other machines.
So, the Mining boards work very nicely for SETI. The major problem for Me has been the Power Connections, I have yet to identify a single 'Bad' USB cable. The BioStar board is using two power supplies at 650 & 530 watts with 8 GPUs rated near 75 watts each.

14 GPUs = https://setiathome.berkeley.edu/results.php?hostid=6813106&offset=6020
8 GPUs = https://setiathome.berkeley.edu/results.php?hostid=6906726&offset=3200

Message 2009064 - Posted: 24 Aug 2019, 10:18:49 UTC

As a "newcomer" to Linux multi GPU crunching I am looking to try and "consolidate" some of my single machines into one so that I can have all 5 of my GTX 750ti's in one box.

Then perhaps my 2 GTX1050's, and my GTX970 in another

I have been looking at Bitcoin mining mother boards as a possible answer and wonder if anyone has any advice on which boards and which CPU's will give me decent performance without breaking the bank

I know I will need PSU's that can cope and I will probably house them the "mining" type chassis with the GPU's on top via extenders.

Any advice will be welcome.

Be careful connecting the x1 risers. if put in backwards or offset too far out or in you will ruin the GPU. Been there, doen that, bought the bricked RX570.

I have seen picture of a mining motherboard that had "usb 3" sockets instead of x1 slots but so far have not seen it for sale anywhere.

Just look at all the posts I made about the BioStar board in the Rosewill case. It sounds as though you are looking to do the exact same thing I did. I just checked, they still have those 12 Slot boards for $33 US. I think I've tracked down the one problem I've been having with the GTX 950 conflict. I replaced the 950 with a 1060 and now I'm seeing symptoms of a failing Power Supply. I think the old 530 watt off-brand is failing. It is kinda old, and described as a 'Hybrid'. I'm getting ready to replace it with a much newer EVGA 750, we'll see how that goes.
If you don't mind not running CPU tasks, an i5-6600K and that 12 slot board will run those 5 GPUs without any trouble. I ran 8-11 GPUs on a similar board with an i5-6600 for months before switching to 12 GPUs and an i7. The i5s are much cheaper than an i7.

If you’re only planning to run 3-5 GPUs, there isn’t much benefit to running the mining specific motherboard. Just pick up a normal board with 6-7 PCIe slots and use that. Generally more stable and built with higher quality components. The mining boards are made as cheaply as possible.

After looking at your selection of gtx 750 gpu cpus I am guessing that you will need to upgrade to a faster cpu? Both Intel and Amd have non-mining MB's with 5-6 gpu slots. I like but have not tested (yet) the $30 mining MB that Tbar wrote about.

I have an Amd 2600 pushing 7 gpus via a Biostar TB350-BTC. I need to get better cooling on it if I want to OC the cpu. You would need an Amd 2700 to push 9 gpus (all riser cards plus an 1 to 4 expander card). And the 2700 would need an bigger aftermarked cpu cooler if you wanted to OC it.

So you are probably going to need a MB, cpu, cpu cooler, ram as well as a larger PSU.

It should be possible to do it for a reasonable cost.

So I should overtake eventually. maybe a couple weeks.


10 days and there it is. my ex-mining machine now 2nd fastest on SETI. . :):):)

Only has the 2080 in it for Wow. After that I’ll pull it and return it to a 7x2070 System. I’m not even running them full blast. Power limited all the 2070s to 165W. And the 2080 that’s in there is limited to 210.

I didn't have much luck either with a 16X to 16X adapter either that I attempted to hang off the last PCIe slot. System would not boot. Seems you have to purchase good quality adapters from an exclusive list of hardware vendors to get a working solution. USB cables are the normal weak link it seems. I would follow all the suggestions from members with well running mining systems as to which and what hardware works well.

As Keith said, and in my experience, the USB cables are usually the culprit. I’ve helped several other members with this suggestion to replace them.

I think I posted the full-lane risers I had good luck with before. But here are the ones that I have running 8/10 cards in my 10-GPU system.

EZDIY-FAB New PCI Express PCIe3.0 16x Flexible Cable Card Extension Port Adapter High Speed Riser Card (20cm 180 Degree)-Upgrade Version

I did have to return 2 of them for being defective after testing, but if you’re ok possibly having to play the return game to get a good one, they are solid. Been running non-stop for about 7 months now. No issues.

The Thermaltake brand risers are more expensive, but have a better track record for quality from what I’ve read.

In any case, if you’re using a full lane riser, make sure it’s a quality and more importantly SHIELDED ribbon so you don’t have issues running full gen3 speeds.

not usually. but anything is possible I suppose if you got some real janky unit or installed it wrong.

which I why I was asking what brand and exactly how you installed it.

what about what motherboard you have? and what slot you tried using the riser in?

also why you think the riser damaged the GPU. what behavior are you seeing?

its hard to answer such vague and open ended questions. please give us more details when you post a question.
