BFG 7800gs overclock

[Velocity]

Hey everyone. I just used coolbits to overclock this card to 490\1.4. Is this too high of an overclock for this card?

It's probably a little high for the core (most people on air are getting around 470 here without any problems), but for the memory it's probably a bit low actually. I as well as a lot of other people with 7800GS's have been able to max out coolbits memory bar and still have plenty of room to oc. I was able to get another 110mhz off of mine before i started running into problems.

I recommend using rivatuner to overclock. In order to use it with the 7800gs (because the program does not recognize it) you will need to do this:

Open RivaTuner.cfg ( You can find this file in RT's folder) with notepad.exe.

In [GPU_10DE] section, you will see " NV47 = 90h-9Fh" , add " , F5h" at the end of this line . Then it will look like :" NV47 = 90h-9Fh ,F5h".

Tell us of your results! Good Luck!

what do u guys think the max overclock is for a normaly cooled (no water or anything) BFG 7800gs right now my core is at 430 and mem clock at 1305 using rivaltuner.

Get coolbits and use the "detect optimal frequency" button. THen run 3D Mark 05 and 06 a few times, play some games and see if it is stable and if it artifacts. If it artifacts or is unstable, back it up a little.
