Hey guys.. I'm having a little trouble getting my 3570k passed 4.0 GHz.
I've set Multiplier to 42, LLC to High, Turbo and Speedstep off, and manual voltage from 1.15 to 1.2 and can not get it stable in Prime 95. I'm using an Antec Kuhler 620 in Push/Pull so my cooling is adequate.
Are there any other things I need to look into, I know that is a quick and dirty way to OC but it's been rock solid @ 4.0, just completely unstable above that.
you could try turning off LLC and set the voltage to 1.2 and see if you can get 4.2. You should be at 4.3 or 4.4 at 1.2v though but every chip and motherboard are different.
Looks like High is set to 50% LLC and Ultra High is 75%.
I think I have better success with Ultra High. I ran Prime 95 last night for about 45m with 1.2v & Ultra High LLC @ 4.2. Temps were around 60-65' so it looks that this combo might be a winner.
It's my first ever OC, and looking at other people's setups it looks like I've been extremely fortunate to get that much out of it. I set the memory profile to XMP and set the multiplier to 40, booted the pc, ran prime95 and used Asus's OC utility to add multipliers and voltage until it wasn't stable anymore, then backed it off a bit. Then I went and put the settings in the UEFI and it's been like this for over 6 months now and haven't had so much as a hiccup.
