View Full Version : List your BFG 6800U OC overclock results...

I have a BFGtech 6800U OC and would like to see if I can get it to Extreme Edition speeds.

The detect optimal frequencies in the driver panel spit out 440/1170. I got the core to 450 fine, but I have reservations about the memory.

Can you tell me what others with this card got their cores and memory to?

Also, what grade of GDDR3 does BFG use? Is it designed for 1200mhz, or 1000 and simply overclocked to 1100?

I have the eVGA (unmodded) and tops for the memory is 1135 stable. I run it at 410/1.1 with no problems in any of the games I play or have tried.

My guess is your card has GC20 memory chips with improved cooling. GC16 will get above 1150 but is only available, as far as I know, on the Ultras.

He said he has an BFG Ultra OC.


d2thez, I also have the BFG Ultra OC and I can tell you that YES you do have the 1.6ns GDDR3.

As far as my overclocking results.....I can get the core to 456 without artifacts using the stock cooling on the card. On the memory side, I can get up as high as 1280 completely stable. I am sure yours can get to at least 1200 no problems.

Detect optimal is usually a somewhat conservative estimate. Ive done it, and it always comes back with 1160(1.16) or 1170(1.17) on the clock frequencies page. To test your memory leave your core alone and only up clock the memory and test it out...possibly by running 3dmark03 and seeing if you get artifacts at that speed. IF you do, drop it down a bit and try again. I would first suggest you try 1200 and see if it works fine...which it should. The try 1250 and see if it works fine. Run 3dmark a few times at this setting to check to see if temps affect that memory setting. If after a few runs through and you get artifacts, then you don t wanna keep it at that lvl and need to drop it a bit. If you are fine, then you can bump it to 1260 and test again and so on. Most ppl tho usually dont get better then 1240, 1250 unless they have some special cooling going on. Id have to say Im a bit lucky to get 1280 just on air cooling. Im sure I could get quite a bit higher if I was using water.

525 1290 stable but all games like FarCry and Doom 3 are good to go for hour or 2 but ut2k4 after about 4 maps of play screen freezes with white pastey background and have to cold boot but everything else of golden

cheers all

You should have mentioned that your not using stock air cooling to reach that 525 core clock speed

Ello,

My BFG 6800 Ultra did 1.2Ghz on the ram with the stock air, however with the Danger Den NV-68 i can reach 464mhz on the core, however i think it can do more however the 'test' instantly fails for some odd reason but i dunno what else i can do.

I'm running at 450/1250 with no lockups or heat issues.

Seems BFG went with the good stuff...1200 on the mem has been a breeze with no issues.

450/1.25 here with stock cooling stable. ;)
