Hi m8s!

I will be short. Look @ the configuration in signature.

Well... I start the PC, I run the 3DMark05 1, 2, 3 times ok... starting from the fourth or fifth it could give a bit more that half points than before... and I don't know why... I see it from the beginning because the starting framerate is 15 in stead of usual 27.

It isn't a temperature problem because it happens even if they are low and in any case if I wait letting the PC having rest for half an hour and I repeat in the same Windows session the result is still bad.

It isn't a system memory problem because if I run Super RAM and I free it (I have 1 GB, no need to free it, anyway I did it anyway) the result stay bad.

If I reboot all return normal... for the first 3/4 times of course... after bad, etc.

The problem doesn't deal just with 3DMark05, in fact it happens also if I play for a more or less long time at Counter-Strike: Source... I'll try to explain: in stead of playing the first 3 3DMarks I can also play CS:S and after run the 3DMark... it will give bad result from the first or the second time.

There is no way to fix the problem except for rebooting (but it is a temporary fix, because the problem returns).

When 3DMark05 runs bad, also the other 3D Application run slower, example:
Doom 3 --> before: 66, after: 62 FPS
Counter-Strike: Source --> before: 108, after: 104 FPS
3DMark03 --> before: 10180, after: 7500 PTS

3DMark05 --> before: 4480, after: 2500 PTS


My tries:
-> Changed MB bios.
-> Changed AGP Aperture Size from 32 to 512 MB (perhaps just a bit changes).
-> Changed Forceware driver. Before 71.89 WHQL official, now 76.44 WHQL.
-> Changed NForce Driver. Before 5.10 WHQL official, now 6.37 WHQL (IDE and Ethernet still from 5.10).
-> Changed the processor clock and v-core (to 2200 Mhz @ 1,75)
-> Changed the video card clock (to default)
-> Changed the paging file size and also the "cache setting" in stead of "program".
-> AGP Voltage from 1,5V to 1,7V.

What the hell can I do now? :(

What could it depend on in your opinion?

Maybe try some older drivers... Make sure u installed chipset drivers..?

Older driver?! MMhh...

Sure chipset drivers are installed correctly.

GPU voltage may need to be increased, the drivers can disable pipelines on the fly when it detects rendering errors, if that stil doesn't help then the extra 4 pipeline you enabled might be dead.

I'd try increasing the GPU voltage to the max available in the cards bios, if that works then you should try enabling the last four quad pipelines before overclocking the GPU higher.

Really? Do drivers can disable pipelines on the fly?! Anyway without the quatrin added it should not drop like that, in fact I made 24 FPS in stead of 27 starting the 3DMark with just 8 pipelines on, while when the problem presents itself I have 15 FPS!

I'll try with the GPU voltage.

I have solved the problem. Actually the 4 added pipelines give artifacts just in some rare cases of rendering (no artifacts with 3DMarks or Doom 3, I have seen some just in some textures OUT OF THE PLAYING zone in cs_office, lol, so neither Half-Life 2 or CS:S), anyway drivers don't make them pass the test and that's why I had the problem (driver stress test transitions make the card go slower because driver tried to downclock it to solve the "problem"). I have solved just flashing a bios with the frequencies I used before overclocking with RivaTuner, so now drivers don't detect any overclock and don't check even the pipelines, FPS don't drop and I can play 12/6 without any problem (as if they were perfect)! :D
