i7 950 3.6ghz overclock safe?

post #1 of 15
Thread Starter 
I just recently got into overclocking, as I was just curious how much more I could get out of my GPU and CPU. My GPU has a tool to overclock it from Asus, and I'm not really too worried about that anyways. However my CPU, is something I'd really like to get up there. It's an i7 950 @3.07ghz stock, and I've overclocked it to about 3.66ghz. Stress tested for 2 hours and it got to 81c max and was hovering about 77c, so I believe that's safe, but I really don't know anything about the volts safety. I mean absolutely nothing; I looked it up and just confused myself. Here's a screenshot of my CPU-Z
window, however.



I believe that gives enough info; if not, what else would you need to see? Basically, I want to know if I need to turn down the clock a bit, if it's perfect where it's at, or if I even have some room to go higher. All I did to overclock was changed the BLCK from like 133 or whatever it was at to 153. It's quite hard to find a tutorial for this BIOS, and I can't really follow the x79 Asus tutorials too well as the BIOS is completely different.

Thasks, Nash.

3.66ghz is fine for your 950. For voltages I guess anything under 1.4v is considered safe unless you're benching with adequate cooling.

I had my i7-860 at 3.8ghz with 1.36v but I'm pretty sure Bloomfield has better OC-ability than the Lynfields.

You can try raising the PLL voltage to see if you can get a higher stable clock. I had to do that with my 860 or I was stuck at 3.6ghz.

first off welcome to ocn. i've had my i7-950 stable at 4.6ghz @ 1.45v for about two years and never had a problem. but i was running on water list your hardwere mobo,ram,psu,cpu cooling and were go from there

Alright, thanks. I'll look into the PLL

With a 950 you should be able to do 4.3-4.5Ghz

Really? Under safe temps and everything..?

Update: Put it at 162 BLCK getting me to about 3.8ghz. Idle temp is about 52-55c, 100% stressed at 89-93c. Is that bad? I mean, how often will the CPU get nearly that used up? Got it up to 4.1ghz earlier, but I stressed it at 75% and it went to 94c, so I figured it should be a bit lower. Running at 1.424v, so would you say this is safe to run in the long term?

thanks for the info here's some things to try to bring your temps down first off enable speedstep, disabled c1e, Intel Virtualization,turbo,Spread Spectrum. them set your cpu multi to 21 or 23 ( i7-950's do better with odd number multi's ) next enable llc to full ( load line calibration). my i7 liked 21 multi 200 blk = 4.2ghz on air max temp while stress testing was around 82 but you will never reach these temps day to day even while gaming. also in windows under advanced power settings the processor power management for the cpu make sure the max power is 100% and minimum is around 60%. then stress test for a while if it passes start drop voltage on the cpu until it does not pass the stress test

What cooler are you using? Hoping not the stock cooler
