Few questions about Bottleneck.

post #1 of 16
Thread Starter 
Hello everyone,

So lets say I have a HD6850 with my AthII x2 250 @ 3.0GHz, when I will have lower FPS in lets say BFBC2, at 1280x1080 medium settings, no AA or at 1280x1080 (or 1600x1200) high settings 4x AA. This is one thing I dont understand about bottleneck.
Also is it even worth overclocking the AthII x2 250 so it doesn't bottleneck so much the HD6850?

Thanks!
Sorry if my english is bad.

I don't know much about amd, but I used to have an old pentium 4 chip with 2gb of ram powering my pc, I swapped it out for a quad core i5 and 8gb ram and it was such an improvement! If you overclock a bit you might squeeze a bit more performance out.

you can't get bottlenecked on high res like 1600x1200 but i dont understand is that custom res "1280x1080?" or you mean 1280x1024... ^^

and overclock your 250 .... 1.45 or 1.475 voltage / increase the fsb to 250
drop ram speed 2 times drop HT 2 times and reboot ^^ -> you'll get 3.75ghz ^^ + no bottleneck

I don't know if this helps, but my x4 620 is barely keeping up with my gtx560, there isn't much noticable bottleneck, but it's there.

You are bottlenecked in BFBC2 because that game loves quad cores. The more speed you can bust out of your dual core the better, but you would see a bigger difference if you just upgraded to a quad core.

I don't / haven't played much processor intensive games, but my 4ghz athlon II x2 doesn't have much bottlenecking issues with my 6870.

Im just asking if overclock will help with the HD6850, because I probably wont be able to upgrade to new CPU any time soon. Also will even the HD6850 be so hard bottlenecked I cant play games like MW2, BFBC2, MW3 (For BF3 will be hard, yup). Thank you.

EDIT: I've been wondering is the GA 870A-UD3 (rev2.1) "Bulldozer Ready"?

Only the GA 870A-UD3 rev3.1 states having AM3+ compatibility,however we won't know if 8xx series chipsets will work with BD until it is released.
Overclocking the CPU and the CPU Northbridge will help ( make sure you have sufficient cooling,but the stock cooler can handle a low OC),as well as OC'ing the HD6850. I noticed a 8500GT in your sig,is it what you are using now?

You should be able to play those games when you get a 6850. There will be a bottleneck but the 6850 isn't very expensive and dropping down to something like 6770 could shift the bottleneck back to the GPU depending on what resolution you're running.

And yes, like we've all mentioned, overclocking will definitely help your framerates. It would be worth it for you to overclock
