Assassin's Creed Brotherhood slower AFTER overclocking!

post #1 of 24
Thread Starter 
Hello!

I've got a i5 2500k, H70 watercooling, AMD Radeon 9860, 4GB 1600 RAM, and a Asrock P67 Extreme 4 mobo.

Managed to get up to 4.4Ghz so far, 50C, 1.3Vcore. Stable on maximum IntelBurn Test on max threads. Memtest86 no errors.

Question -

AC Brotherhood runs at around 40-60fps most times when I'm running at 3.3Ghz, prior to the OC. However, after OC'ing it's constantly slowing down and going at 20-30fps! Whats going on here??!

Thanks guys!

Radeon 9860? O.o
Also fill your system specs under your User CP panel. So we can see all the details.

Well, it can be various things, how many pass did you do of IBT? Did you try p95 blend test? large ffts?
I found that IBT is good for extreme temp testing, but prime95 blend/large ffts are more for stability wise testing. I had a computer run 50 pass of IBT and crash blend test after 2 hours.

That psu should be more than enough. I'm a bit clueless at the moment. Can you run some kind of test that uses cpu+gpu? Maybe 3dmark06?

It would also help a lot if you filled your system's specs.

Do you by any chance use Vertical Sync?

This game is really buggy with vsync enabled, I tend to get as low as 30fps with vsync enabled on my HD6970 CrossfireX, but if I disable vsync, frame rate jumps to +100.
