Cliff Harding -

I think I have the issues you raised covered. I have Precision X installed and running. It starts at boot-up. Actually, I have the fan set to max (74% for some reason) to keep the GPU as cool as possible.

I have tried running only one Einstein GPU WU with no other "CPU only" WU's running, and that didn't help.

Thanks for the ideas though.

RE: Horacio - What you

Quote:

Horacio - What you wrote is consistent with my situation. The mouse moves around OK. And after 30 seconds the computer realizes what I have clicked on. Then the computer goes to "sleep" for another 30 seconds. Also, the computer (except for the screen) is running. I can access it over my local network with no delays in response. I wonder if you see any errors is the Windows Error Event log.

Nobody316 - I started with a 2GB memory module. Then I added a 4GB giving me 2GB+4GB. I am not sure what part of that 6GB is the 4GB Windows uses. Then, I pulled out the 2GB module, leaving me with the new 4GB module. So, I essentially have tried at least two different memory chips. I could move the GPU plus 650w power supply to a 2nd computer but the 2nd computer has exactly the same MB and processor. Somehow, that seems like a low probability of success.

As I wrote before, sometimes one just has to accept the fact my combination of H/W, S/W, etc. and Einstein aren't going to get along.

When you install memory ALWAYS put the biggest chip nearest the cpu! This is NOT necessary on ALL motherboards, but it will fix some problems on those that care, if you ALWAYS do it! The way Windows uses memory on SOME motherboards is from the cpu outwards, so putting the largest first means Windows will load all of itself on the biggest chip and then use the other one for overflow, instead not having enough on the first chip and then overflowing to the other one. Now I do not think Windows uses the whole 2gb so in your case it may not make any difference.

ALSO having different sized ram chips can be a problem for those pc's that use paired memory to be faster. You may find that getting another 2gb chip and pairing it with your existing 2gb chip is faster then a single 4gb chip. If you still have the mb book it should talk about these things, depending on how old the pc is. IF it is faster you could perhaps then trade in the 2gb chip for a second 4gb chip and have 8gb in the machine.

There is another setting you could check and that is in Boinc itself, go into Boinc Maanger, down by the clock, and check what the setting for "while processor usage is less than {} percent(zero means no restriction)" It is under Tools and Computing Preferences then the Processor Usage tab. Alot of us have changed that to zero on 24/7 crunchers, but since you are having issues it may be better to change it back to the default of 25 and then see how it goes. A higher number means Boinc runs less often but the pc is more responsive, a lower number means Boinc runs more and is less responsive. The number represents how much processor usage is FREE before Boinc runs, so if you are using the pc for something Boinc would stop and not interfere and then run again when you are done with what you were doing. There is also a tab called Exclusive Applications and that means that whatever the program listed is in there Boinc does NOT run! If for instance you put your moms program, IE if it is browser based, then whenever she is online Boinc stops and when no one is using IE Boinc runs 24/7 at 100%.

Along with the GTX660SC/2GB I'm also running an EVGA GTX460SE v1/1Gb, with both running 2 tasks each along with whatever CPUs are available. I say available, because if I am running Opencl those tasks will prempt the number of cores they need. You don't really need to manually set you fan speed to max as the speed will only go to 70, even though it shows 74. I believe that is a limitation set by nVidia.

Have you ever thought of upgrading to Win7 64-bit, your ram will be greatly improved. I'm running with 6GB on both of my machines.

Tried AMD once some 40 years ago, had so many problems with it I went back to Intel and been with it ever since, same with ATI cards. Sorry I couldn't give you any more help.

BTW, FOR THOSE THAT ARE INTERESTED SETI IS BACK UP!!

I don't buy computers, I build them!

To put an end to my saga of

To put an end to my saga of trying to run Einstein GPU’s using my GTX 660, I decided to “downgrade†and I purchased a GTX 560. I installed this on another computer with the same MB, same processor, same amount of memory, and same OS. Of course, that doesn’t mean they are identical.

I think the suggestion that Alintope made on 05 Feb might be the answer. That suggestion was that it might have something to do with trying to run a PCI-e 3.0 GPU on a PCI-e 2.0 MB, even though it is supposed to be backward compatible.

In any case, I am now happily processing Einstein GPU WU’s on this second computer, along with SETI for now.

I still wonder why SETI and Milkyway run OK on the GTX 660, but I will not be losing any sleep over it.

Seti and MilkyWay even though they are using the same Boinc program, probably anyway although there COULD be Server version differences, each wrote their own software to process their own workunits. It is kind of like Word and WordPerfect, both run under Windows but both do things differently.
