Should I pull the CMOS battery?

2.8ghz is regular stock speed for 930, it's 920 that was stock 2.66ghz

Edit: Sorry, Boost aka Turbo

930 turbos to 3.06ghz

Yes, I believe you're right, I must have the 920 D0, sorry about that. So is there a way to take it all the way back to stock settings, or should I go in myself and lower the x21 multiplier?

Turbo is a stock setting. Although you can turn Turbo OFF in BIOS then it will stay @ 2.66. But Turbo is safe and is a standard Intel spec. You only normally turn it off when overclocking as it can mean bad overclocks.

Hey there,

I'm following your guide for my 960, because I couldn't find any guide as comprehensive as yours(Kudos!) but I had a question. I see in the guide you say to raise QPI by .25v each step. I assume that is a typo, and you mean .025v?!?! starting at 1.25, then stepping to 1.5 seems really harsh. I don't feel comfortable with that, so I'm gonna wait to hear from you about it biggrin.gif

I went through the first 10 pages or so looking for someone to mention that and I didn't see anything, lol. Hope it hasn't already been answered.

Cheers!

I would suggest going up one step, only adjust to what the cpu needs...if it needs it then it needs it.
With my overclock of 4.0 and 4.2 I only +125-+150.
So just adjust accordingly and and always keep notes, heck maybe even make a spreadsheet of the settings that failed/passed. Good luck..

hi guys!

thx to the guide i've overclocked my 930 to 4,0ghz - stable so far. nevertheless i've reached a point where i don't know what to do next. i thought there is some optimization required, but i dunno where to start.

Since you have a 930, you should use the 21x multiplier. Odd multipliers overclock better than even ones. Run 21x191 for 4.0 GHz. You should turn on C1E and EIST after finding a stable overclock, otherwise your processor will never downclock during idle.

All of this is stated in the OP. Read it over and over again if you have to...

This thread was very helpful. I managed to oc my Xeon W3520 to 4 GHz!

THANK'S ALOT FOR THIS THREAD!

Even though Prime95 crashed due to overheat, all 20 tested games ran fine at 50 - 60 Celsius, so it's a stable OC!
Prime95 testing is not everything - you need to have a very good cooler to run through Prime95!!!
