i7 990x at 4.5Ghz Good or Not? Also Bottleneck?

post #1 of 10
Thread Starter 
Well I have a fully stable i7 990x cpu at 4.5GHz with a cpu voltage at 1.37 (Don't no if this is a good voltage for a 4.5GHz overclock) And I can say this is fully stable because have run prime95 27 hours on "Small FFT's" and about 20 hours on "blend" also run Intel Burn Test 200 passes no problem. But what I wanted to no is this overclock of 4.5GHz good enough? I have heard graphics cards getting bottlenecked well if they are running in sli or crossfire due to the cpu. I hope this cpu at this speed will not Bottleneck my graphics card well I will be going sli soon with my gtx580 maybe overclock it a bit to.

The graphics cards will get bottlenecked by a slow northbridge or HT but i dont think a faster CPU would bottle neck the cards. BTW sweet OC that is quite the monster system especially with it being that stable.

I highly doubt that cpu at 4.5ghz will be bottlenecking anything.
post #4 of 10
You will not bottleneck that cpu/mb no matter the clock. Period

That OC is fairly typical of a water cooled 990.

I wouldn't expect CPU to be the limiting factor in more than a handful of real world gaming scenarios.

You'd be surprised... It's all based on the games itself and how powerful your GPU's are...

My CPU overclocked at 4GHZ definitely shows signs of bottlenecks...
Games like Batman: AA, Rage, Deus Ex, Starcraft II get me around 60-70% GPU usage for both (other than Rage and the non sli issue)

Other games like Crysis, Metro 2033, Heaven Benchmark get me 98-99% useage...

What? There is no HT on this? Or NB overclocking... This be Intel /not/ AMD biggrin.gif

You will not be bottle necked one bit.

6 cores @ 4.5Ghz? Yeah, no bottlenecks here.
