11) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28140)

So, I guess what I would request is, what would be considered good Nvidia cards to put on a new machine, and what in the way of specifications for a power supply?

Here is what the Maingear F131 Super Stock would have
Intel® Core™ i7 3930K Six-core 3.2GHz/3.8GHz Turbo 12MB L3 Cache w/ HyperThreading.

MAINGEAR EPIC 120 Supercooler (CPU cooling)- but that looks like a water cooled system and I have had bad luck with that, so I would ask for air cooling similar to what I have on the Shift Super Stock.

Intel® Turbo Boost Advanced Automatic Overclocking

16GB Corsair® Dominator™ Platinum DDR3-1600 Extremely Low Latency 1.5V (4x4GB).

The choices of Nvidia cards are way too plentiful

2x EVGA® GeForce™ GTX 680 SuperClocked 4GB Total GDDR5 In SLI w/PhysX [ENTHUSIAST - OC]
2x EVGA® GeForce™ GTX 680 FTW+ 8GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]
2x NVIDIA® GeForce™ GTX 680 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]
2x EVGA® GeForce™ GTX 670 8GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]
2x NVIDIA® GeForce™ GTX 670 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]
2x MSI® GeForce™ GTX 660 Ti Power Edition 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]
2x NVIDIA® GeForce™ GTX 660 Ti 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]
2x NVIDIA® GeForce™ GTX 660 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST]



The SLI can be disabled, but since BOINC wants device 0 and Maingear wants device 0, I have SLI enabled on the Shift Super Stock. If either was O.K. with device 1, then I would not be doing this.

1TB Western Digital VelociRaptor SATA 6G 10,000rpm 64MB Cache
This was actually the last change made on the Shift Super Stock. This is alleged to be an "enterprise grade" (whatever that means) hard drive normally used in servers.

Power supplies available are
850 Watt Corsair® AX850 80+ Gold Certified Modular Power Supply ROHS
660 Watt Seasonic® X-660 80+ Gold Certified Modular Power Supply ROHS

So, this is a lot to ask, but I find people here really know their stuff.

Any opinions, and I know they could only be seen as opinions, will be gladly received. I am not about the business of building any machine myself. I am only about the business of paying for what works.

Thanks in advance for any and all replies.

MrS

Thanks. I did run HW Monitor for a while. It never showed anything untoward regarding GPU temps. My power supply never failed, I was always able to get something to happen on failures, even if the machine refused to boot.

And, you know, I did manage 17 million credits on GPUGrid before I gave it up.

My GPU's are GTX 670's, air cooled. We tried sealed liquid coolers, but they repeatedly failed.

Even if the GPU's did overheat, I would think that would have initiated a shutdown of the crunching before actual damage to the cards. I believe that is what happens when CPU's overheat, a machine will shut down prior to damage.

O.K., now I know the score on ATI.

So, I could go the other way: I could run GPUGrid as the only GPU project on the current machine, and run the others, EINSTEIN, SETI, and add MILKY WAY, on a machine with ATI.

But, there remains the question, part of which I posed above: is there any reason that GPUGrip would create difficulties on any machine with decent Nvidia cards when it is the lone GPU project? After all, before I finally quit the project, it amassed 17 million credits.

As I said above, this machine was rebuilt three times suspecting other problems than problems caused by any one project. It only calmed down once GPUGrid was no longer running.

I was planning out a new computer, a Maingear F131, with the express purpose of crunching GPUgrid. I already have a machine, a Maingear Shift Super Stock with Nvidia GTX 670's. For whatever reason, GPUGrid did not do well on this machine. I had to detach from the project.

This machine kept failing. It was totally rebuilt three times, and what finally seems to have settled things down has been the removal of GPUGrid. Why this was a problem I have no idea. GPUGrid was the impetus for this machine. The machine is currently doing GPU crunching on EINSTEIN and SETI so far with no difficulties.

Maybe various GPU projects just do not play well together.

So, I wanted to plan the new machine with ATI cards. Apparently, GPUGrid does not run on any ATI cards.

Am I correct about that, and is there any hope for the future?

If you don't have a problem with a driver then don't upgrade.


That is my mantra, Thanks.

The 301.42 driver (and higher) will be ok.


Thanks. I am relieved. Playing around with Nvidia drivers is not my cup of tea.

So, I am on CUDA 4.2.x; but driver 301.42. There was a new driver out, maybe 304.x or 306.x which we were advised to avoid.

So, what would be the proper driver number now acceptible?

Thanks.

I have a computer the sole task of which is to crunch especially GPUGrid and other GPU projects. My configuration is to not run GPU while the computer is "in use".

Since BOINC is all this machine does, just looking at the task list gets really boring. Just for variety, I thought about running project screen savers. But, does this constitute the computer being "in use", would screen savers stop GPU tasks from running?

Thanks.
