Phenom II x4 965 BE Bottleneck

post #1 of 27
Thread Starter 
I am overclocking my Phenom II x4 965 BE to 3.8ghz. Right now i have a 6950 2gb. But later on maybe this summer I want to crossfire it. Do you think my cpu will bottleneck the gpus. I want to trade my cpu for a 1100T and cash but cant post on the marketplace. So if anyone is selling or trading. Also I am running at 5760 x 1080.

Get your cpu to 3.8GHz which you have, but also get your cpu-NB to 2800Mhz. This will alleviate some of the bottleneck of two 6950s. Don't waste your time with a 6core 1100T, almost all games use at most 4 threads.

So just setting the voltage to 1.25 will make it 2600mhz

Apart from processor power after seeing the resolution you game at there is no way 2x6950's will be bottle-necked. Keep the present processor you have as no game requires more than 4 cores. Infact as of now most games play best on an overclocked x3,not :)kidding here at all.

You have it the wrong way around. You will have to up the multi in BIOS first, the adjust the voltage to suit if it starts crashing with the higher NB.
