does anyone here use MSI Z77 MPower mobo and overclocking? im using this mobo w/ a 2600k.. i want to tweak it a little... hope someone can help me... thanks... biggrin.gif

Which value is better in offset mode: -0,095 with LLC5 or -0,150 with LLC1 ? Both are stable and the CPU-Z reading for vcore is the same. Is there any difference at all ?
post #10513 of 10701
The difference will be at idle, where -0.150 might cause problems. Maybe try something in the middle, like LLC3?

go for the lowest voltages you can get away with all round. no point in doing a higher offset voltage with lower llc in an attempt to get the idle/low clock voltages higher if they don't need to be for stability. unless you're getting crazy voltage spikes with a high llc setting. but you don't sound like you are.

I don't know if those are crazy. When I have LLC set to 5 Prime95 max vcore is 1,240v but hwinfo reports that it reaches the maximum of 1,256v while playing Far Cry. Is it fine that while running Prime95 I get 1,200 to 1,240 or am I doing something wrong ? It passes several hours of tests without even one error.

If it's stable, then it's stable! Just aim for the lowest idle and full load voltages you can get away with. Or don't worry about it and just leave it as is. Depends how far you want to go with dialling in your overclock.

But if you're using Prime95 to test. Then you're gonna need to do a custom blend test, modifying the settings so that you will get at least 90% RAM usage. It will take about 18.5+ hours to pass all the FFT's. But if that's too long. Then you can try doing what I do these days: Modify the blend test in the way I just mentioned, but also change the setting to run each FFT for 10 minutes instead of 15 minutes. This way you can pass them all in about 12.5+ hours. Others may like to be more thorough, which is fair enough. But for me this is an acceptable test. Also, before you run the blend test. Try running individual tests with each of these FFT's: 1344, 1792 & 2688. So for the first test you would set the minimum and maximum FFT size to 1344. Set it to test each FFT for 1 minute. And make sure you set the RAM usage high so it's pushing past 90%. Run this test for 20 minutes. Then repeat with the other 2 FFT sizes. These are the most troublesome FFT's for Sandy Bridge CPU's. That's why it's good to make sure you pass them before the blend test. You might already know this stuff as it's all in the guide here. But just thought I'd mention all that incase you missed it. Good luck thumb.gif

it takes longer than 12.5 hours. it took me 17 hours roughly to pass every fft test in blend at 10 min tests.

that's interesting. maybe it's changed now. because when i submitted to this club a while back with 4.5ghz, i'm pretty sure i passed them all in about 18.5 hours on the 15 minute setting. i do remember when i did another test last year with a newer version of p95, i wasn't sure if i'd actually passed all the tests, or whether the order that they run in has changed. do you know where i can get an up to date list of the order that the fft's run in? can't see it on the prime95 page..

i have no idea. p96 27.7 took me about 17 hours and maybe it was 14 hours. my brain keeps telling my 17 and im too lazy to find my post in this thread.
start 9
p95 and let each fft size run for 1 minute on a single core. you can easily find out how many there are by the finished fft in the results log. im currently doing it now as i cant remember and it is something no one ever asks. its nice to have worthless info rolleyes.gif

i sent you both a list in pm and attached a list in txt in that pm

if anyone wants a copy of the list
fft.txt 2k .txt file
