Overclocking problems with 7900GS

post #1 of 7
Thread Starter 
Hello all, I have a problem, and hopefully its a noob problem thats easy to fix.

I have a XFX Geforce 7900 GS (The 600M XXX Version) that is factory overclocked to 600/800. I also have an Arctic Cooling Accelero S1 cooler with the Turbo Module (two small fans that sit on top), and it kicks ass. I just bought a 22" monitor and I want to game at the higher resolution but of course, my fps drop from good to crap.

So, I want to overclock my card, but I can't get it to overclock. I've tried using ATItool, CoolBits, and Rivatuner with no sucess. When I try to raise the core/memory clocks up and apply the settings, the settings switch back to the stock clocks immediately. This happens in every program, and it doesn't matter if I raise the clocks 1mhz or 100mhz. It is weird, and I can't figure out the reason for it.

My idling temps are around 30-35C and load temps usually don't go over 45C, so I think I have PLENTY of room to overclock.

Hopefully I'm just having a noob moment

Other PC Specs:
Dell XPS 410, Vista Home Premium (32-bit), Core 2 Duo E6600 2.4ghz, 2GB RAM, 7900GS w/ artic cooler.

hmm...thats odd. maybe you just arent using ATITOOL correctly. Put the clocks on what you want (put the 3d one up first) and save it as "overclocked", and see if that does anything.

Tried it, when I raise the clocks and save it as new or create a new profile, nothing happens; it continues to show my stock speeds no matter what and I can't change them.

I think its because its a POS Dell and has locks on overclocking, but its an after market gfx card and I've read around all day and found people with the 410 who are overclocking their cards (just can't OC the CPU).

I'm just pissed of because I've been trying to figure this out all day long and have gotten nowhere.

I also tried another program called PowerStrip to overclock it and it does the same thing.

Thanks for the suggestion though!

Not a very likely cause, but do you have the most recent nVidia drivers? If not, update to the newest ones from nVidia's website.

Another thing is, although your temps are low, they were like mine with my VF-900 on it at 600/900, but without a voltmod I couldn't push much farther then that. After volt-mod I have achieved 700/900(didn't v-mod the memory as it has no heatsinks on it), but what I am trying to say there is that you probably can't get much more frequency out of it without raising the voltage unless the 600M XXX version comes with a higher voltage standard or something.

Gah, I was coming to that same conclusion...thanks for the reply

Actually one of the first things I did was update to the latest drivers, Forceware 169.25. Are there any other drivers that I need that I don't know about?

I was thinking that voltage might be a problem, but I've heard of other GS's being clocked over 600 core stock, who knows though.

It's just very weird, I've never seen any program just reset back to stock settings as soon as I hit the apply or OK button, and when I try to find the max core/max mem in ATItool, it never raises either of the clocks; even after running it for 8 hours straight.

Any more ideas?

yea ati tool did that for my 7900gs too, just use auto find the max core and memory

just read above post, and i'm stumped. Maybe remove the drivers and use driver cleaner. Then get some drivers from nvidia. If all else fails, bios flash

Tried removing all nVidia drivers, restarting in safe mode and running driver cleaner, then restarted and installed fresh drivers. - same result.

AHHHHH! Its driving me insane! lol
