Hi,

my WUs are going wrong? I've this problems for weeks. (But I haven't not crunch much in this time in common) In this days, I aborted a WU cause the computer was turned off most time and I could not finish not nearly before deadline. Two other WUs started and were running for a time, but failed after a fraction of whole run time.

I know that my 9800GTX+ is not the newest/fastest GPU but it should be able to finish WUs ..

I checked the temps of GPU while computing, it was round about 45°C.

Thanks a lot for your suggestions.

Best regards

Sebastian

Hmm, maybe i've coosed the wrong forum. Please move thread if this is the case. Sorry and thanks.

ACEMDlong takes about 600 MB VRAM, do not crunch it on 511 MB VRAM GPU, set your preferences to acemd2. I mean skgiven is going to send you PM what to do overall to be succesfull, if not post msg., i'll send you some recomendations.

Hi , clockspeeds, can have a big impact, on every nVIDIA GPU running GPUgrid
WU's.
I run my X9650(3GHz)@3.51GHz and the GTX480 on 1.6GHz, temps are (below)normal
50C for CPU and 80C for the 480, atm.(Air-cooled, open, no case, PSU is @ 35C).
Room temp, can cause the 480, when running 3 SETI at a time, running the fan at 80% doesn't get hotter, bcs, fan setting is based on GPU+RAM temps.
I still use 1 250, but the noise it makes, will force me to take it out and
seek another suitable (GTX470) card. Also have 1 side off and a extern fan blows
air in this side.

Compaired to a lower clocked 480 0.8GHz, speed isn't a lineair function of the WU crunch time.
(Impact on SETI WU's are much bigger, if using the anonymous LUNATICs app. x32f,
FERMI compatible, also runs on 200 series and even lower 8000 &9000 series).
The 'older' 8000 & 9000 series run a high clock-frequency, as do some of their
'newer'(G92)GTS250 (8800GT;9800GTX+)

Runtime/load-unload time of the CPU are less, probably through the overclock.
MFLOPS and frequency are alomost lineair, @3GHz 3000MFLOPS, @ 3.51GHz 3520MFLOPS! (10965M Integers)

Those Longruns work OK, 2 faults, but do give a nice credit!
I don't even know, if the 480 have a 'default setting', probably a factory setting.

Knight Who Says Ni N!

Hi skgiven, so you are saying that 9800gtx+ is probably not able to handle long runs correctly because of low computing power or because of Compute Capability 1.1? What is weird that standard tasks are always completed successfully on my Asus 9800gtx+ Dark Knight however each long run WU fail saying: SWAN: FATAL : swanMemcpyDtoH sync failed. very strange because I never saw such error message while computing standard WUs. I had some issues when I started to compute gpugrid because of faulty memory modelues (now replaced with new modules which were tested with memtest and prime95). Low card memory is not an issue neither because WUs do not use more than ~230MB for computing gpugird (checked with gpu-z). GPU temperature never goes higher than 56-58 C (depends on ambient temp). Card is slightly OC (6% gpu and shaders) but I already tried to use default frequencies however this didn't help. I use swansync 0 parameter, shall I try to disable this and use only GPU computing power? Or it is not worth and I should stick with standard WUs only?

Thanks for help or some hints.
