2000 pts drop after overnight 3DMark2001 run on Gainward GF3 Ti/450 GS card

[gogoman]

Are anyone out there experiencing a significant drop in 3DMark2001 score after running the Benchmark loop mode for a long time(overnight)? My gainward card GF3 ti450 at any speed setting runs great but shows about a 2000 point drop after an overnight run on default benchmark loop indefinitely mode.

For instance, I get a 3Dmark2001 score of 7909 at 240/480 setting. After an overnight run, I get 5390.
This is happening even at 200/450 setting. I noticed something was wrong when the frame rate gets really low after some time, especially during the "vertex shader" test, where things started getting really choppy.

Are you running on etiher 98 or Me?

This is a problem with your system running out of memory (not video memory but SYSTEM memory.) Run it overnight, then restart and see what you get

After 2 hrs of my gainward gf3 ti450 at 235/545, my nature fps dropped from 35 to 15, it is runnin out of mem.

I am running Window 2000 with 512 MB (2sticks) of crucial memory. How is it possible that it is running out of memory?? There is something about the gainward card that is doing this. Anyway, I have returned that card, got myself a Leadtek GF3 ti 200 and is testing it now.

 

[Y23KC]

Then you have a memory leak. Then it doesn't matter if you have 50000mb of ram. I'm telling you, it's running out of ram. If it runs fine at first, then slows down, the ram is all used up. Nothing to do with your former card.

 

[gogoman]

Is there a way to verify there is this leakage?

I see no big deal in this, unless u enjoy watching 3dmark 2k1 for hrs and hrs. In gaming, i wouldn't think it will lose considerable performance if u play for several hrs that is.

If you don't reboot at least 20 times in one day for hours of benchmarking, either you are newbie, or you don't want to get good scores. Simple rule. I assuming we all know this but I am saying this just in case someone doesn't. You gotta reboot each time you run benches like that. Running twice before rebooting is okay too. Same thing works with the Q3A bench. Usually get best score in the second run, and in some case, third run. 3Dmark 2001 get best result at first run after fresh reboot. Understood????

 

[gogoman]

Thanks for the info. I am not running the benchmark for the score but for the measure of graphic card stability. I guess if this is normal if you don't reboot, then great. Unfortunately, with my new Leadtek card, I can't tell if this drop in performance is happening cos my system keeps rebooting itself after some hours of running. Is this normal?

 

[MilkPowderR]

Could be your Power Supply getting too much heat and losing stability on the voltage flow to your mobo. Usually, if the CPU gets too hot, then it freezes instead of random rebooting. If the System isn't getting the voltage sufficiently, or if the OC is too high for your system AND the PSU, it'll reboot also. I've done lots and lots of trials and error things and didn't even eat and sleep sometimes. Now, what I said doesn't mean it's 100% true cauze there are more things involved that just this and not all systems behave the same way like mine. The quality of the Mobo also matters depends on the OC level.

I have noticed 3DMark2001 nibbles away at my available memory...... (as will many 3D apps.)
(well, actually that was with win 98... I haven't looked for it with XP.... bet it does tho)

especially noticable if you end and restart the program with no re-boot....

let it do the long loops for checking stability, but always re-boot prior to benchmark runs

 

[gogoman]

Yes, doing the long loops with my previous Gainward card GF3 Ti450 GS card without reboot made it seemed stable but upon closer examination, the lobby and vertex shader test were showing choppy-jerky motion. You are saying this is normal cos the program eats away at the system memory?

I never had this "system rebooting itself" problem during the long hours of "loop indefinitely" mode with my previous card but with the Leadtek card I am getting this problem. Perhaps the Gainward card is more stable than the Leadtek card?

I have not noticed this with my GF3 Ti200, but then again I do not run my benchmarks all night. a couple runs satisfies me as far as stability testing goes. Check out my Gainward with modification pic below...

 

[RgrPark]

your system rebooting just means that it crashed with the infamous nvidia infinite loop BSOD...you just have windows set to reboot automatically after a crash that is all.

 

[gogoman]

No, I disabled automatic reboot long time ago.

 

[billyjak]

Get a program like memturbo to refresh your ram on the fly. I use it and it works well

Hey thanks a lot.

I must say, BEAUTIFUL WORK, Mr. Duffy.
