Sandy Bridge 2600K / ASUS p8p67 Deluxe OC problem - Page 2

post #11 of 17
Thread Starter 
Okay, so here's what i've got specifically:

C1E - Enabled
EIST - Enabled
CPU PLL Voltage set to 1.8125
VCore set to 1.440
load line calibration - auto
phase control - extreme
turbo mode manual, OC set to 4.5 on each core.

Now, this seems to run stable. I've run prime 95, intel burn test, watched my temps and did a little gaming to which everything seems to run perfectly stable.

However, if I try to increase the OC on each core by one (4.6), even with several small bumps to the vcore I can make it to the desktop, but it freezes up.

Now, the ram is running at 1333, should I increase it to it's native 1600 speed and see how it does?

Increasing one clock speed really doesn't stabilize another You probably need more voltage.

What are you temps full load and what cooler are you using?



Oh, BTW, not all CPUs are the same when it comes to OC'ing.

1st of all, i'd like to thank everyone for their help. I've read the posts, articles, and followed some links in others sigs to get a better idea on how sandy bridge operates and the settings tweaked to achieve particular numbers.

Now, after reading and following advice i'm at what appears to be a stable 4.8 GHZ @ 1.480. After I see how the stability holds up i'll start bumping backwards until it's no longer stable.

Here are my temps under load: http://screensnapr.com/v/2IKYft.png

why don't you enable Load Line Calibration?

Hey Sin -
After reading some of your stuff, I did just that, and i easily hit 5ghz - just wasn't very stable... might go for hours then blue screen... and the thermals were a little high.

I backed it down to 4.8 ghz @ 1.465 vcore, ran some benchmarks, prime, intelburn, and played some games and everything seems to be running great now. Also running cooler. 32c at idle, and 77c under full, extended load (this is just where it tops out at on one of the cores, the others are around 70c under load.

I'm happy with that I suppose
