Hi, I recently upgraded my cpu from the Fx 6200 with a EVGA 660ti to the 8350 with the same gfx card, and got a nice 990fx sabertooth r2 mobo with Corsair H60 watercooling to go with it. I definitely noticed a FPS gain from the 6200, but not anywhere near what I was expecting. I don't know what I am doing wrong.

When i first got the cpu, I ran BF3 at 4.2 ghz that was automatically set by the mobo, and I was getting 120 fps! Then after oc'ing the CPU myself to 4.7ghz, as well as the gfx card, I get 60-80 fps on ultra, dipping low as 45. That pisses me off. I don't know if I overclocked correctly, my temps with the H60 w/ a push pull set up has the temps 65 C on load with prime 95. I unparked my cores as well. In Arma 3 Alpha, I'm getting 45 fps, but dropping to 35 fps. What I didn't do was do a fresh reinstall of Windows 7? Or should I go to Windows 8 for better performance? Or am I fine? Did I overclock correctly? Should I go down in my speed? What should I do???
Please Help me- PLEASE NO INTEL/AMD FLAME WAR!

ugh... cpu-nb is the nb pipe, and the ht is hyper transport. hyper transport is the memory controler. they both deal with memory to cpu communication, and practically speaking they're part of the same hardware, but for overclocking purposes and our purposes think of them as seperate entities that serve the SAME function, only you have to get both to work right for that function to work right. generally speaking your HT speed should never be faster then your cpu-nb. so bump up the cpu-nb then the ht, most bios will keep you from bumping the ht over the cpu-nb... but it's still...
make sure ALL your power saving features are turned off (quiet and cool, mostly)... if those aren't turned off your system will throttle back your cpu automatically which could be the problem.

if that's not the problem, not all overclocks are the same... but it sounds like to me your cpu is running faster then the ram can feed it info. this can have a negative impact on performance.

Look at boosting your cpu-nb and hyper transport speeds. look at overclocking the ram a bit too. overclocking isn't just about the highest cpu speed you can get, it's about total system speed. The FX 8350 does not have a performance cap, it's performance will continue to scale with higher overclocks, so you're handicapping it somewhere else. My guess is the ram.

Look into overclocking the Ram, HT/CPU-NB and boosting some of those voltages to stabilize the system when you're through. You should see a nice build up in performance.

Right. I have all of the power saving feautures turned off, ie cool and quiet etc, and I think maybe RAM might be an issue. When I oc the CPU, i increase the FSB instead of the CPU multiplier to get the 4.7 Does this have something to do with it, or is it better or worse?
 


ok... well improving the FSB will push your ram clocks higher. your ram might be hickuping, it might be undervolted... have you tested your system stability with something like prime95?

furthermore, overclocking your ram without boosting your cpu-nb or ht won't work. those need to increase as well.

+1 check your RAM voltage and try IBT or prime95

Right I think you might be on to something. How do i boost my cpu-nb? DO you mean voltage? And ht is hyperthreading right? How would i increase that?

when you raise their speeds you'll probably need to raise their voltages, and likely the ram's voltages eventually too.

That said, your FSB overclocking will raise the HT/CPU-NB speeds as well as the ram speeds. So i'm sure the whole memory (RAM) system is unbalanced and in some weird state of overclocked/undervolted. you might actually have to lower the clocks for the HT/CPU-NB and ram to get the most out of your system. I don't know. it will take some experimentation to figure it out.
