The other 20% will be still be using by the os, processes, etc. Don't worry, it is not a static quantity, it just stress that amount of ram. If you do not like HCI memtest (wich is considered by many as the best for ram stability), you can use intel's xtu ram tests, p95, etc...

Maybe yes maybe no, AIDA 64 stress test is not very hard to pass to be honest, try RealBench or OCCT as per the opening post smile.gif

How long would you run realbench for

At least an hour with maximum memory would be a good starting point, pass that at that voltage then it would be fair to say lottery winner as 1.35V is very low for 5.2Ghz

Personally I try to keep below 80 degrees C but others might say higher opinions vary same as stability very subjective smile.gif

the auto settings for 3600c15 will push vccio and vsa. you can lower these by alot. should be no more than 1.2 vccio and 1.25vsa. I have that kit running 3866c15 (1.45V) with vsa at 1.175 and vccio at 1.15V. AUTO and VOLT are 2 four letter words. wink.gif

@peter2k - the question was overclocking and secondly features. Not sure what you believe is missing from the Apex... but sure, compared to the M9 Extreme, EVERY board is lacking. smile.gif

The auto setting as in memory timings? Because I already set them manually to 15/15/36

I have never been able to boot my memory higher than 3600 under any settings, not even manual timings specified by XMP profile.

I suspect my 7600k isnt the best out there as I require close to 1.4v to even get 5GHz stable. :-(

Edit: For the first time i managed to boot with XMP 3866 profile, got into windows and did some aida64 benchmarks, then rebooted, and no post.
Trying again for 10 times no post... I wonder why my board has such issues posting on 3866+.

Perhaps i should mess with bootup voltages.

under 80 would be ok, a bit on the toasty side, but ok
it would be less in games anyway
and with a delid it would come down to more reasonable temps obviously

to get a good guess an hour is fine

for entry here in the list you would need 8 hours with maximum RAM

it's good to let it run overnight that way

I had voltages set thinking it's stable only to have it halt at around 4 hours, repeatedly
had to bump up voltage in small steps until it passed 8 hours
so there is a reason why it's 8 hours biggrin.gif

also remember there is a benchmark and a stress testing button

you want the stresstesting one thumb.gif
