I do have another question regarding Core Voltage and LLC. In the guide, it says to choose between LLC2 or LL3 depending on which is closer to the BIOS vCore. My guess is the Core Voltage displayed in CPU-Z is the actual voltage but where or how do I find out the BIOS voltage? Thanks for the time.

Well it depends on your motherboard ...but for me...my vcore in BIOS is under H/W Monitor section.

but anyways, how am I doing? smile.gif

oh and btw, temps never touched 70C smile.gifthumb.gif

Yeah that looks good man...def. see how high you can go without passing 75C (Prime95) and 80C (IBT)...should be able to hit 4.7ghz without a problem. I thought you had a 3570k (runs hotter)..for 2500k (runs cooler) that is still good, but not as golden as I thought...lol tongue.gif Either way you are looking pretty stable to me for 4.5ghz. Once you find your max overclock (that you are happy with)...run Prime95 and IBT with the settings i mention earlier. i think you've spent enough time with 4.5ghz...unless this is where you want to settle.

yes this is definitely where I want to settle... I'm not gonna push it any further smile.gif

Thank you for all your help!

Update from my post on pg. 86

I ran Prime95 again and it failed after 3hrs.
Bumped Offset up to +0.015 (Vcore between 1.176-1.184)
Prime95 ran 12 hours no errors

BUT, checked Windows log and found 5 WHEA errors during that 12 hours

201

Questions:
1) My Turbo voltage offset is set at +0.004 as per guide should this be auto as n1x1n has set?
2) n1x1n did you check your WHEA errors?

I will keep increasing offset in +0.005 increments, but it's sooo tedious.

hmmm...now that i think of it...I NEVER checked WHEA errors...I didn't know at the time....crap....I guess I need to re-run Prime95 for a while...

And here I was thinking I was 99.999% stable passing 12 hours of Prime95 on 93% RAM and 50 rounds of IBT on max ram.....

Just thought you should know.smile.gif

Windows Hardware Error Architecture (WHEA) provides a common infrastructure for handling hardware errors on Windows platforms. WHEA is intended to reduce mean-time-to-recovery for fatal hardware errors through richer error reporting and to reduce system crashes related to hardware errors through effective operating system hardware error recovery and health monitoring. WHEA enables the Windows operating system to effectively utilize existing and future hardware error standards, such as the Processor Machine Check Architecture (MCA) and PCI Express Advance Error Reporting (AER).

Hello, couple of questions. I ran Prime95 blend in 14 hours without errors and warnings. The settings are based on the guide including x44 multiplier, +0.005 offset (cpuz displays 1.28v), +0.004 turbo voltage, auto CPU PLL (bios displays 1.832v). I'm content with this speed, do I need to set anything else or I just leave it at that?

Second, I tried increasing the multiplier to x45 but it hangs on the windows(vista) splash screen. I tried increasing, decreasing the CPU PLL voltage to 1.709 and 1.89, and also increasing turbo voltage to +0.008 and +0.010. It still wouldn't allow me to boots windows. Does it sound that I missed a something like settings a feature to disabled?

Third, afternoon and night temps here in my room shows about 10c temperature. The 4.4ghz peaks 71c during the hot afternoon but only less than 58c during the evenings. Is there a way to "turbo boost" the cpu during the evenings so I don't keep changing the bios. That is if I learn how to get to 4.5ghz.

Thank you very much.

If I am considering switching to a fixed mode for the overclock because from what I understand, it will make my voltage fluctuate less under load.

Is this correct? And if so, is there a guide anywhere/is there anything i should or shouldn't do?

Thanks

I like offset better...keeps your PC voltage lower when you don't need full power....why run more voltage thru your CPU when you don't need it? but to each his own.

I personally, LIKE voltage fluctuation...as long as it working correctly...stable at idle...and stable at load...I see no problem with this...in fact, I think it's more ideal than keeping voltage fixed. Not to mention cooler on idle.

Guide...is on post #1...i used it...seems like all you really need to understand offset imo.

Well everyone has there preferences I guess. I'm stable at like 1.24 v on prime 27.7 and when I try I get it stable at the same speed on offset I need about 1.3v under prime load. When you overclock w manual you dont have to worry about idle Stability because your voltage is always high enough. When your voltage is way below Intels max specifications it shouldnt really have a significant effect on longlivety because most of that comes from CPU at load/hIgh temps anyway...

While good for reduced idle voltage, offset mode requires a somewhat larger voltage stability margin to account for the fluctuations; for IVB at 4.6GHz+, this becomes a conflict of interest wrt temperatures.
