Welcome to the club usop and lord

Seems like you need a better cooler bro.

good attempt. Your GFlops is too low and not stressful enough
Try latest LinX + win7 SP1?

pretty sure any third party cooler will beat Intel stock cooler.

Made a few tweaks to my 4.5GHz OC:
1) LLC dropped from High to Low (for lower VCORE under load as my board doesn't support under-volting )
2) BCLK returned to stock (was causing random issues when waking up from S3/S4/S5 state)
3) RAM upped from 1600MHz to 1866MHz (Trying to learn about timings, but those sub-timings are driving me )

For 4.5GHz you're gonna need a new cooler... The stock HSF is simply too "thin" for the job But still, nice clocks for 1st attempt

if you're talking about bottleneck, slow ram wont draw back your CPU OC.

Suspect there's power leakage or short circuit in your casing.
Make sure that PSU cables are not contact with casing.

Added on August 11, 2012, 2:43 pmWhat about no OC? Will it happen? Might be bad OC also because windows will save settings during the shutdown process.

What cooler are you using? You still using the Tuniq tower 120 extreme? Low voltage oso high temperature... Maybe you need better cooler  . Can try reapplying TP and repositioning your cooler?

He's using stock cooler
