Overclocking i7 920 on P6X58D-E

I re-seated the cpu again and cleaned it and the hsf block up. Put a pea sized blob of AS5 on and re-built. I then followed the guide from post #10 but changed the vcore to 1.14375 and the qpi to 1.23125 (increments of 0.025). Temps at 3.6 are:

My temps idle were:

Core 1 - 39c
Core 2 - 34c
Core 3 - 39c
Core 4 - 33c

Temps after 1 1/2 hrs Prime95:

Core 1 - 70c
Core 2 - 67c
Core 3 - 68c
Core 4 - 63c

Big change from before and no BSOD so far! Will see how it all goes before I attempt any further meddling!

Couple of questions though before I go:

Is increasing voltage in increments of 0.025 the right way to do it?

The guide I used never mentioned re-enabling speedstep so is it something I have to do?

Thanks for the help and advice guys, will be back later for some more :)
 
That's much better temp-wise! I find it's easier to start higher with the voltages and go down until it doesn't work any more, rather than starting low and having to keep increasing voltages until it works. I started at 1.25 V for 3.8 GHz and 1.3 V for 4 GHz.

Enabling SpeedStep when you're done is just common sense - no need to have your CPU running at full speed using full voltage all the time when you'll only need that speed occasionally.

What a load of rubbish. Almost all i7 920/930s can reach 4 GHz with safe temps and voltages if you have a decent cooler.

agree, all the chips overclock at 4GHz, I just remember watching a utube review on them (think it was an overclockers3D review) and hearing that unless you want a fridge freezer inside your machine cooling it down the 950 is the most suitable to clock at 4GHz.

But yes you can definately overclock them all to 4GHz
 
CPU temperatures between 920s, 930s and 950s are the same. Obviously there are the odd chips that are quite a bit cooler or warmer than the average but there's no more chance of that being a 920 over a 950, or vice versa.

The only difference is the 950's higher multiplier means you can have a lower BCLK, which theoretically stresses the motherboard a bit less (although this doesn't actually make a real-world difference - no mass reports of early adopters' overclocked X58 boards dying...yet).

i was going to be buying me 950 within a month but after hearing you say that i may just go for a 920 as i was going for the sabertooth mobo and i'm only guessing here but i doubt the sabertooth will experience much of the extra stress from the cpu been clocked at 4GHz.

if anyone has actually got a sabertooth mobo and a lower i7 chip than the 950 clocked @ 4GHz and can post their findings i'd really appreciate it, i'm very curious now as i could save a little of the cost from the 950 to put towards another 6GB of memory sticks.
 
My boards not to far of a sabertooth, actully few diff tweaks on mine for better power delivery but thats about it really in terms of overclocking.

Iv managed 226bclk without really pushing it, so the bclk won't be an issue, also had my 920 upto 4.6ghz with HT on, stable, but temps where high.

But ofcourse each cpu is different, and cooler used is key factor aswell. But i would'nt worry about using a 920, the sabertooth will handle it for fun..
