The title of the thread seems a little misleading. It’s more referring to GPU-based cryptocurrency mining rigs, not specifically Bitcoin ASICS, which is what you have.

Good point, so I added "GPU-based" to the title.

I think the summary result should be "Yes"!

Tbar's Intel-based 19 gpu slot board running 14 NVIDIA gpus with an Intel i7-6700K (discontinued) (4c/8t).
So he is basically running 0.5 cpu to 1 gpu ratios (I think I read that).

He is getting that giant RAC using 3 gtx 1070's and a lot of gtx 1060 3GB's and 1 (I think) gtx 970.

So if you already own a lga 1151 socket cpu someplace near an i7-6700K you can probably replicate Tbar's results without sinking a lot of buck's into gtx 1080's or RTX anything's. Re-use your cpu, ram, get a robust Bitcoin-based MB with a lot of gpu slots, riser card kits and.....
Move all your Nvidia gpus onto one box (actually a Mining Rack will probably make more sense). Yes you will probably need to plug a couple fairly large PSU's into the MB and different cards.

And if you already have an Amd AM4 socket cpu/ram you can hang up to 9 gpu's if you use Biostar's Am4 Mining MB (6 gpu slots plus a single 1 to 4 extender card). Still likely need a mining rack though.

I love this idea, but my wife didn't...so I have multiple boxes around the house.

and that right their is consumer side. why its not taken off.

Actually, it's not much different than MacOS. The biggest problem with any OS is the Video driver, that's why Apple builds the driver into the OS, and the latest move in Ubuntu to to Install a recent driver during first install. If you install Ubuntu 19.04 you will get NV driver 418.56 installed automatically, all that's left is to copy the All-In-One to your Home folder and double click-boincmgr. Currently, Ubuntu is the Easiest OS to get BOINC up and running with a NV GPU of any OS. If you have your GPUs spaced around two inches apart they will run without any manual fan settings, and very little is gained by trying anything other than stock settings.

There it is.....

TBar, Average credit = 596,216.41
Tod, Average credit = 595,617.40

Three 1070s
Ten 1060s
One 970

Are there Intel cpu's for the LGA 1151 (1150?) socket for the mining motherboards that are greater than 4c/8t?

So far I can't see any. It would be really nice (if it wasn't too expensive) to get up to a 8c/16t or so cpu driving upto 19 gpus slots.....

I have looked and socket 1150 & 1151 are much more expensive than 1366. A shame no mining socket 1366 boards. If there are any 6/12 out I was unable to spot them on eBay. There must be some deficiency with express lanes on socket 1366 as I cannot get 4-in-1 to work good on my older motherboards. I have a pair of 4-1in-1 on a TB85 (socket 1150) and do not see any degradation and currently have 9 GPUs under Linux.

the only "mining" aimed motherboard that can support a CPU with more than 8 threads is the ASUS H370 Mining Master. here: https://www.asus.com/us/Motherboards/H370-MINING-MASTER/

you could put up to the i9-9900k (8c/16t) into it once you update the BIOS to the latest version, it could also take the i7-8700k or i7-8086k for 6c/12t. performance is probably an unknown, i doubt anyone has put that combination together. The VRMs on that board look woefully inadequate for that caliber of CPU and you're looking at $300-500 for a CPU, but it might "work". From what I've seen, that board has roughly the same 13/14 GPU limit as the previous board, you get the full board only if you use some mining specific cards.

I was also looking at boards with USB 3 built in and was unware of that Asus model. The only one I had seen previously was this

I have been alerted via eBay tracking that my returned "fake" gtx1050ti is undeliverable. Another "middle man" it seems.

i wouldn't buy any of those Chinese one off mining boards. you have no recourse if it fails. it's the same with the ebay chinese "x79" boards. some work OK, but you have to be prepared for the board to fail and lose any investment into it.

is ebay going to give your money back from the fake gpu even though it was undeliverable.

I think I saw this board announced but no one has it in stock.

I am confused. Probably by Intel's naming convention(s). Are you saying that this lga 1151 MB will run those higher thread cpus but other lga 1151's won't?

Yes exactly.

It’s because of the chipset used.

Z270/H270 or B250 motherboards do not support the new CPUs and Intel forced users to upgrade the motherboard if they wanted the new CPUs. No BIOS updates were or will be released to put the new CPUs on the old boards regardless if some could handle it. Some users modified their BIOS to get the new CPUs running on the old boards with varying levels of success.

The new boards are Z370/H370. They got an updated bios to support 9th gen Intel processors. Technically Intel wants you to use a 390 series board for 9th gen but they supported 370 with a bios update. But you can’t use the old chips in these new boards either.

There are Two different groups of Intel 1151 boards, the distinction is pretty clear as here,
Intel® Socket 1151 for 8th Generation Core™ i7/Core™ i5/Core™ i3/Pentium®/Celeron® Processors
The Older 1151s work with 6th Generation & 7th Generation as here,
Intel® Socket 1151 for 7th/6th Generation Core™ i7/Core™ i5/Core™ i3/Pentium®/Celeron® Processors
Since the Bitcoin boards are designed to run as many GPUs as possible as Cheaply as possible, there isn't much of a market for boards with Expensive multicore CPUs. Why run 12 cores when 8 will run 19 GPUs without any problem? I have personally run 12 GPUs on a 4 core i5. The problem was after around 11 GPUs the i5 times started slowing down, so conceivably, there shouldn't be a problem running 20 GPUs with an 8 core i7.
Since NewEgg screwed up my last order for a 12 slot 1151 BioStar board I placed my backup Mining Expert into service, I now have Two Experts running. If I ever receive the 12 slot board I'll place one back in the box for a backup. I see the Experts are back over one hundred, I'm glad I bought that last one when it was at $64, it seems to work fine.

Should be another 1070 here this week, we'll see how that works in the 14 GPU machine...

The box seems to be working fine with six GPUs. Right now I have a Gigabyte Z270P-D3 board installed and it can only run 6 GPUs.



I did modify the case so you could mount a GPU in the first slot on the board by cutting a hole in the case so the DVI connection was accessible. With the faceplate removed it's a perfect fit and the case can now hold 9 GPUs. With 6 lower-end GPUs, and five 120mm fans, the temps are running in the low to mid 60s even with the top on. I ordered a 12 slot board, but it was the wrong board in the open box and is being returned. Strange the box and board serial numbers match but the box says Intel 1151 12 slot and the board is AM4 6 slot. Must have come from the manufacture that way, I wonder how many of those are around. It might be a while to get the 9 GPUs working in the case.

Finally, the new 12 slot BIOSTAR board arrived today. It's been working in the case for a couple hours now. Right now it's running 7 GPUs with a GTX 750Ti in the one x16 slot running the monitor. That covers 2 slots, but, still leaves 3 open slots and the case only handles 9 GPUs...it's all good ;-) Apparently my new 6 pack of connectors is still in China somewhere, once those arrive I'll try the last two GPUs in the case.
This is the board, currently running an i7-6700K,

It's pretty much the same as the Gigabyte FinTech board I tried a year ago, hopefully this board won't suffer the Gigabyte 'Failure to PowerOn' fate, common to Gigabyte boards. I got an open-box board, for $61 US, about the same as the case. Really, it's about all you need to do some serious SETI work. The ASUS Mining Expert is still going strong 24/7 since early January and has just reached it's peak, and the spare Expert board is back in it's standby box, just in case....

Oh, they do have New boards for the Generation 8 & 9 GPUs, and they have more Slots, but, I plan on sticking with my SkyLakes for a while. If you have a Gen 6 or 7 CPU, you might buy one of these boards soon, the 'new' old ones will probably be hard to find once the new boards are out, TB360-BTC Expert

OMG....
Blowout Time. I went to NewEgg to see if they had the Newer boards and saw this, + 50% off w/ promo code OPENBX87FIFTY, limited offer
Ladies and Gents, boys and girls, that is applied to the Open Box price of $61.99!! Yes, a 12 Slot Intel 1151 board for $33 US!!!

I'm not sure if this is just a clearance, or perhaps the solution on what to do with a Boatload of product in the Wrong Boxes. The Box I first got was clearly for an Intel 12 Slot board, but contained an AMD 6 Slot board and the serial numbers matched. So, what do you do about that? Send them All back to Taiwan? Or perhaps, make a Deal with the manufacturer to have a fire-sale on a boatload of Open Box boards?
I dunno, but, I bought another One... for $33 US ;-)

You can run up to 12 NV GPUs on this board, All running the CUDA Special App, that's a boatload of production for $33.
This is My $33 board currently running 7 lower end GPUs, https://setiathome.berkeley.edu/results.php?hostid=6906726&offset=1240

OMG....
Blowout Time.

THANK YOU! Just got it ordered. Yes I still have to order a high-end cpu. But I think I saw some used ones that were under $100 on eBay.

Plus I am not sure if I will immediately implement it or not. But since I am a devoted large gpu#'s fan, it is nice to now have an alternative. It will let me use all the "leftover" gpus I have and get up to a 10 gpu box (at least).

Is there any noticeable performance hit for the GPU when using the single lane instead of x16?
