Why won't my 6600gt hold a clock?

[LSANTHRAX]

I've been messing with this thing since yesterday and i can't even get it to stay at stock settings of 500 core and 1g on mem, it keeps rnning as 300 core and 1g mem. The card temp doesn't go above 55c and i dled cool bits and tried settting it in there and it still didn't hold i also tried the detected optimal frequencies and they wouldn't hold either. Then i tried setting it in powerstrip, which was also a no go. But powerstrip did say that the card was at whatever speed i set it to but when i would run 3d03 it still read it at 300/1g

When i click details in 3d03 it reads the clocks as 300/1g as well no matter wha ti set them to so i don't know whats goin on and its really starting to get annoying. I'd atleast like to get it running at stock if not overclock it.

Its not at 300mhz core, its at 500, or you'd never get anywhere near 9000 points...300 might be the 2d clock for the 6600GT, i dont own 1 myself so im not 100% sure on this. also, would be a good idea to get the 66.93 drivers

[LSANTHRAX]

ok i've got the 66.93 drivers and 300 is the 2d :banana::banana::banana::banana: for it, i guess its just not updating it to the 3d clock once the program opens the 3d part of the bench?

[LSANTHRAX]

Allright it seems i've got it to where it will keep the clock speeds i set now.

Anyone know of a way to run dx 8.1 with the 66.93 drivers on xp?

[sr4470]

66.93 is good for 3d'03 and 05 but im not sure about 01, ive stopped using it because its a :banana::banana::banana::banana::banana: to get a decent run, i use am3 now for benching (its pretty cpu-limited even with my current setup)

the 6600 gt is also supposed to be 900mhz clock on ram at stock, even though it uses 1000mhz chips :D my 6600gt will be here tomorrow yay!

ok one last thing to add to this thread, is it ok that my vid card got so hot after like 14-16 hours of hard game play in a row that it would over heat and i had to exit? Or should i send it back, this was a stock speeds i just don't know if its deffective or if after so long the heat build up is just too much for the card.

[LSANTHRAX]

Well i seem to be talking to myself but oh well, since i figured the card was allready fubared i toook of the heatsink to find it was making little to no contact with the core so i cleaned off their old gunk and added some as5 some testing now and seems to idle at 47 and full load at 65 degrees C which is about ten lower on idle and i don't know how much lower at full load, all still with stock cooler.

[LSANTHRAX]

Any suggestions here guys, at the cards default clocks from xfx the memory gets hot enough to artifact in games, i cna either buy some ramsinks and hope that helps it or try and cleen up the as5 i put on it and send it back to xfx as deffective and get a new card?

I know its been stated, but 2D clock is 300MHZ, and since 3DMark opens in 2D Mode, it reports your 2D clock.

Oh and, I dont know who said 6600GT's come at 900MHz stock, but most, if not all PCIe 6600GT's come at 1GHz, and atleast 1/3 of the AGP versions do too.

I got the Asus 6600GT PCX Extreme it runs
2D @ 300 / 1000
3D @ 500 / 1000
1.6ns memory
Very nice card...
I have 8300 with a single card non oc in '03

So 1000Mhz on mem is not that exeptional.
Temps realy are nice @ 47°C load
