i7 overclocking - Page 3

It's a Thermochill 120.3 radiator, designed for computer water cooling, and Danger Den TDX block. For water flow, I go from pump to cpu; it's not that powerful of pump that I am going to worry about the heat add.

The i7 has no problem running up to 85 or 90C (core temp, not die temp. My die temp was shown also in the pic, it was 48C).

It's not quite stable as it is. During torture test Blend with 3 GiB ram used, after had been going a few hours, I was watching a video in media player classic and halfway through the system got the BSOD. That's what has been happening when instability is happening; not getting errors in Prime95, just a freeze and BSOD. And the BS just gives generic "Unrecoverable Error" message.

Not sure what I want to do right now, probably just accept 4ghz and not run Prime95 for a while. Will come back in the near future and find a setting I can run 24/7 but I don't feel like it now. I'm comfortable with 7 hours Prime stable at 4ghz for non-Prime95 usage.

PROTIP: If you have to remove the PWM heatsink for some reason, DON'T remove the thermal pad and replace it with thermal paste:

Needless to say I need a new motherboard... and I have no way to test my CPU/RAM to see if it was affected by the blowup, until I get a new motherboard.
