SoG is significant faster than cuda 32,42,50. Cuda 90 is only for Linux. The only developer able to import it to windows is MIA. So don’t look for it anytime soon. SoG requires 1 full code per work unit. The cuda don’t. But SoG is significant faster. OpenCl is restricted to only 26% of all gpu Ram. So bigger the ram on a gpu the more we you can use. Higher end gpus have faster rams so they are quicker than lower end. Multiple work units on higher end will deliver better results. 3 in 15 minutes or 5 minutes per work unit. I was able to get it down to 12 minutes. Linux cuda special now is around 75 seconds so it no contest.

I think that 75 seconds is on Gtx 1080 or 1080Ti?

I am seeing 2 1/2 minutes to 3 1/2 minutes on Gtx 1060 3GB's which is what I think he ordered. I was getting 7+ minutes under Windows with SOG (depending on the data crunched).

He will see an astonishing improvement when he converts :)

I only run 1080ti now.

I wish I could afford them.

Thanks guys.

I noticed when I got home yesterday that the miner had a bunch of computational errors.

Anyone know what the deal with that is?

Out of the eight threads in the miner CPU, 8 GPU's ate two whole threads so now the mobo only shows six left and a few of them are barely crunching...

Anyone know what the deal with that is?

The Older Baseline CUDA Apps don't work well in Windows 10 and would be Very Slow on the BLC Tasks even if they did. The New CUDA Apps called 'Special' only work in MacOS and Linux. Macs don't handle many GPUs, so, You need Linux installed. I would highly recommend the Last Long Term Support version of Ubuntu since the New CUDA Apps were compiled in Ubuntu 14.04. Use the Image here, Ubuntu 16.04.5 LTS (Xenial Xerus)
Do Not install any BOINC Software from the Repository. All you need is to Install is the OS, the Video Driver, and the OS Updates. Then Download the BOINC All-In-One package, expand it to your Home folder, install the listed Dependencies, then open the folder and double-click boincmgr. You will be running the CUDA Special App as these two machines,

That's what I would do...

Thanks TBar

Whoa!

There is NO 64 bit i386 for this? YUK!
How is one to get max performance from a 64 BIT machine running a 32 BIT OS?

Oh! Nevermind!

amd64 is the x86 instruction set, so it's Intel as well as AMD. It's also sometimes called x86-64 or x64. So yes, amd64.iso can run on Intel 64-bit processors, just as i386 works on 32-bit ones.Apr 24, 2016

Oddly enough, the miner became sick yesterday so I had to back off the CPU usage to 90% to get it to be stable. I thought for a second that that FX570 card I had in the main PCI slot was the culprit because the video disappeared so I removed it. I didn't know if the system would run like that but it does. I'm getting video off one of the GPU's now. I didnt know you could do that either. I will try my best to get Linux on it today but dont hold your breath. I have to head out this afternoon to a test lab for work this afternoon for Monday AM testing...

The nice thing about the New CUDA Special App is it doesn't burn a full CPU per task. Therefore, it doesn't matter how many CPU cores you have, you can run more GPUs than cores without any trouble. I'm currently running 9 GPUs, No CPU tasks, and my CPU utilization is around 30%. If you are running 8 OpenCL tasks, that means it is consuming 100% of your 8 core CPU just to run the GPUs. You really shouldn't be running any CPU tasks, and there isn't any reasonable way to reduce the GPU usage of the CPU. The only way would be to Use Sleep, but that will slow down the GPUs quite a Bit. This problem doesn't exist for the CUDA Special App. I don't recommend running your CPU at full load for very long, it probably won't respond well to that scenario.

Meanwhile My 9 GPU machine has entered the First page of the Top Computer list and continues to climb.

OBTW, Dave may have the only sun-powered Seti rigs out there. He has enough solar cells to run the entire farm during sun up.

Team,

I am out at the test lab this week so no crunching as I turning everything off at the house before leaving.
I will check back in with you all next week.

Dave

Hey guys. I got the Miner maxed out but I'm not impressed yet. At least using Windows.
Seems no matter what I try, I cannot get more than 12 cards working at the same time but I only have three AMD cards to work with so maybe if I had more of them...
So now I have a bunch more 1060's to put into my other systems replacing the older Quadro 4K's so thats good.
I am going for Linux today!

Dave

So I guess I didnt read the manual for the ASUS B250 Mining mobo close enough. I should have bought more AMD cards than nVidia cards. Seems you need a mix of 11 AMD cards and eight nVIDIA cards to get all 19 going at the same time. I guess Its time to get back on eCrap and do some swapping.

It will be interesting to see how the two AMD cards do in the same system/config as the 1060's.

I wonder if this #NUMBER OF CARDS# limitation is a Windows issue??
Will that go away in Linux?? I mean the mix of AMD to nVIDIA??

Sure would be nice considering I have 19 1060's in my hand...

Before you send the cards away, I would certainly try out Linux. I would also use a different HD so you can guarantee you can go back to an untouched Windows. From what I am reading you literally need the windows HD disconnected to avoid having GRUB (a multi-boot utility from Linux) messing things up.

I saw in a review the MB diagram for 19 GPUs with the Gtx/Amd. But that was, apparently, under Windows.

Apparently it is more complicated than that because there is another Miner rig we are watching with all GTX 1080Ti's and he was running them all under Windows till he switched. He apparently managed to get 13 Gtx's/Nvidias working.

You might get that e5-2670 dual you have back online with at least 2 gtx 1060's. Under Linux with the CUDA91 app, it should run near 100,000 RAC if it crunches 24/7. Not sure what you will get on "daylight savings" :)
