View Full Version : Overclocking my BFG 7800GT Others Experiences?
Hey all now that the GTs have been around fer a while thought I would check in on OCing expieriences.
Mine is the BFG OC, stock speeds of 425/1050
Using rivatuner I am stable at 470/1175
3dmark 05 went from 6900 to 7600 not bad.
Temps up from 46C to 50C
Weird thing was, when pushing the Core I never saw artifacts, but when I went to test at 480 rivatuner told me the test failed and it couldnt set that speed, anyone else seen this?(I did test at 475 and it worked but I like to stay about 10mhz off of max or problem areas)
No one else has overclocked a 7800GT?

I have not overclocked mine yet but, I have been keeping a running tab of review sites OC numbers so I have a good feel for how high I can go when I do :D. Here is the list so far

Interesting so mine is on the lower end for core but higher end for memory, heh not bad

I have a bfg 7800gt I got from dell and its chugging along at 510 core 1.22 memory. Detecting optimal frequencies gives me a clock of 516 core and 1.23 memory :)

Running my XFX 7800GT with watercooling at 490/1150 right now but I haven't even tried any higher settings. I just installed it, ran the slider up to 490/1150 and haven't had a hiccup. I'll probably try and crank it up this weekend.
Mines stable at 450 1.12ghz. Pretty pathetic if you ask me really.

testing for optimal settings says its at 470/1.3. at 470 core,i get very slight texture corruption on stupid stuff (steering colum of the jeep,and thats all i see) but going down to 460 gets rid of the very slight texture corruption on the steering colum. the memory on this card is awesome.so far i got it at 1.4,NO artifacts,no texture corruption at all,so it may even do 1.5. i should note that my case cover is off due to it missing,so with a good airflow case,i could probably due 470 on the core,but its dead air around the card so im sure its not helping. btw,the card is a bfg 7800gt.

edit: the glitches goes away at 440 but my mem is still at 1220 with my pny Verto 7800GT Vivo

I have an eVGA e-GeForece 7800GT and it does 480/1.22. I can take it to 500 core but I start to see some corruption after a few minutes. Idles at 39c load is about 59c, stock fan too. She runs cool.
eVGA is the best, even if I fry it from an OC they will still keep giving me new ones. :afro2:
