Hurray!!!

+1

----edit---
Your using 1 slot to help power the pcie bus? So that is actually all the gpus you have room for unless you use a 1 to 4 expander ---edit---

What I want to see is using the 1 slot to 4 gpu expander cards, how many gpus can you hang off it before the bios screams "insufficient pcie resources"..... Who knows, maybe you can run 15 gpus.

It is supposed to be a gpu server, after all :)

i've been thinking about doing that just to test it. i have two 4x pcie expansion cards. if i had enough spare gpus it would be 16 i could try to fit. i'm sure it would work. this guy here got 18 GPUs working on this board. granted, older cards, but discrete pcie devices nonetheless. 18 GPUs in a single rig and it works

but i'd never leave it like that, GPUs just sprawled out everywhere. i like them to be secured down and kept tidy. so for actual long term operations, i wont go over 11 GPUs, it's all that'll comfortably fit on the rack.

You need a miner rack upgrade :)

I will admit, mine is NOT pretty or organized looking. I have a 7 slot Supermicro dual cpu MB shipped/not arrived. Plus the 11 slot MB that I haven't heard back about.

The ASROCK MB I am using now has 6 pcie slots and 1 non-pcie slot of some type. I am hoping the 7 slot MB will let me get past 9 gpus. But who knows? If I setup a work bench breadboard and see if I can get 10 gpus to be recognized. May have to borrow all my other gpus. Not sure if I have enough riser bases since some seemed to have stopped working as well as possibly 2 gpus now. I think I can get scourge up maybe 14 gpus if I strip out all the other machines. But I don't have enough riser bases for that.

Oh, well.

Supermicro X9DRX+-F

Just found a listing for the above here: https://www.aztekcomputers.com/X9DRX+-F-O-SUPERMICRO-3835847.html

For $162.33! It said it was "Special Order" but I figured, at that price how can I lose? So I ordered one.

If enough of us order, maybe the dealer can get a bulk discount?

Tom

The vendor just confirmed they can't get one anymore.

Tom
ps. Now that I have a suspect gpu offline I am trying 9 gpus again. Wish me luck.... and the ability to run more than 2 weeks without stopping :)

They rise the price to $487.92..... sure at this price they get one.

It is still the cheapest one on the market. Most seem to start at $600-900USD.

In the top 40 on the Leaderboard there are about 9 systems that are running more than 4 gpus.

I believe that Ian&Steve and Tbar are both running at least two systems each with more than 4 gpu's. Me. And some other folk.

Most are running 4 gpus, many are very high end/expensive ones.

But I just did find an 8 gpu system mired in 74th place. Apparently, he/she is running Windows with the stock SOG's. On GPUs called NVIDIA GRID K520 (4095MB) driver: 353.90 OpenCL: 1.2 gpu. And another 6 gpu box mired in 96th place.

That system is actually only 4 physical cards. The K520 is a dual GPU card. So 4 of them equals 8 GPUs. It’s how BOINC handles dual GPU cards.

But I looked through the top 100 or so the other day. A couple people running more than 4 GPUs. I saw that wildcardcorp is back also with 10 GTX1080tis, But he’s running stock tasks it looks like. And looking at his stats, seems like he’s putting most of his power on other projects.

Tom M:

driver: 353.90 OpenCL: 1.2 gpu.

Something I ran into last week. Attempting to run AMD and nVidia GPU's under Windows 10, with newest drivers, doesn't allow OpenCL on both cards. Catalyst 19.3.1 wipes out nVidia OpenCL and Forceware 419.x does the same to AMD cards. Many, many install (DDU cleaned or overwriting install) attempts. Its a testing machine for common baseline testing of WU's for any project I join.

I'll go back to earlier Forceware till I find a version that leaves the AMD OpenCL alone. 388.x probably; is there a good reason they stayed with 353.90 OpenCL?

I have the

Supermicro Server Motherboard MBD-X9DRH-IF

motherboard in.

After going around and around with it I finally got it to recognize one and then more gpu cards in the Pcie slots. I have made it up to 5 gpus today. I will try some more tomorrow. The trick apparently was to "toggle" the pcie slots in the bios. This bios has an entry that is all about pcie's and some other stuff. That is where they hid the above 4G toggle for the large(r) gpu counts.

I am running a "lashup" rig with incorrect cpu coolers while I find out if this can exceed 7 to 10+ gpus. Once it passes 9 gpus, I will feel the urge to buy the correct cpu coolers. :) I just don't want to throw more money at rectangular coolers until I am fairly confident I am going to use this one as my new high end production MB.

Yes, I am only running 3 gtx 1070Ti's on my current big box. All the rest have relocated to close to the MBD-X9DRH-IF MB. :)

I was playing with some of your gpu processing timings and RAC #'s they were being assigned.

It looks like the gpus alone can manage in the neighborhood of 1,280,000 RAC. And then add the production of 36 cpus(aka: 90% of 40) and you look like you could easily top out past 1,300,000+

Which kind? The GBT toaster or the "other one"? :)
