How good is my i7 3770k?

post #1 of 4
Thread Starter 
I finally decided to spend more time on finding my CPU's limits and so far these are the results:

I can get to 4.1ghz without increasing vcore.

4.5 @ 1.208-1.216

4.8 @ 1.376-1.384

I have hyperthreading enabled and I use offset OC and my CPU is allowed to downclock (it goes down to 1600mhz using 1.1v or so when I am browsing the internet, but up to 4800mhz when I play a game or something).

I have not tried 5.0 because of thermal conditions and the fact that my house gets warm. During the 4.8 stress test I hit 102C on the hottest core, and 95-98C on the others. During normal use though the temperatures don't go anywhere near that (between 65-75 max).

Would I get higher clocks if I removed one of my graphics cards or something?

Is how far a CPU can overclock dependent on the CPU itself or the motherboard too?

Thanks

the overclock of a cpu is dependent on three things.

1st motherboard
2nd memory
3rd the cpu itself

now your vcore is pretty goot but that 4.8 giggle jumps is not the greatest as I can get 5 giggles at 1.43 vcore. you'll definetely need more than that to get to 5 giggles.

those temps though aren't appealing at all stay away from those! don't go above 90C when stress testing so back off the vcore and hold down the OC until you either delid or get better cooling. What cooler are you using btw?

I don't know why you'd say the motherboard or memory are more important than the CPU for Sandy/Ivy overclocking. Overclocking the Sandy and Ivy chips is almost entirely dependent on the chip itself. The motherboard makes very little difference, since the BCLK isn't being changed, and pretty much any $120+ motherboard will be able to push a chip as far as air or AIO water cooling can get it. Memory is pretty much completely disconnected from the CPU overclock, although it does slightly affect overall performance.

motherboard vrm's and phase changers can affect overclocking stability meaning more vcore on lower end boards then the memory for the cas latency and the timings along with the volts for them can become an issue. Not often but still can.
