Overclockers topic - 3770K De-lidded and lapped With Liquid Pro - Awesome results.
 

Hi Guys,
Took the plunge and de-lidded my 3770K as even with my huge loop, 90c at 1.28v and 4.7ghz was stopping me testing any further and I really want some more clocks. Also, my core temps were very uneven which has always niggled me.
Plus - I just wanted to do it for the hell of it, so off we go... :)
Quick test beforehand using ten runs of IBT on normal yield the following results.

• Idle Core 1 = 31c
• Idle Core 2 = 26c
• Idle Core 3 = 29c
• Idle Core 4 = 23c

• Max Core 1 = 76c
• Max Core 2 = 88c
• Max Core 3 = 83c
• Max Core 4 = 79c

After the work was completed, I performed the same test, and yielded the following results.

• Idle Core 1 = 27c (-4c)
• Idle Core 2 = 24c (-2c)
• Idle Core 3 = 26c (-3c)
• Idle Core 4 = 22c (-1c)

• Max Core 1 = 53c (-23c)
• Max Core 2 = 56c (-32c)
• Max Core 3 = 58c (-25c)
• Max Core 4 = 54c (-25c)

An incredible max improvement of 32 Degrees C!
And importantly, the cores are now all within 5c of each other, instead of 12c as they were previous, which I expect is a result of the lapping.

Just to be sure it wasnt a fluke, I put ona quick double run on Max settings. results are almost identical. :)

Pleased?
Oh yes! Now for some more volts and clocks! :D :D :D

IHS was definately concave... that pleased me. :)

Pop her back in with some Liquid pro...

And that is pretty much that. All I can say is TAKE YOUR TIME.

Rush this and you will slip and wreck her... but take your time and its very simple to do. :)

nice results - thats a huge difference!

After some weekend tests and more benching, it seems I lost teh silicon lottery as my best overall settings with 100% stability are 45x103 for 4640mhz @ 1.27v with ram at 2200 with 1.55v.


That said, I have also brought the CPU PLL voltage down to 1.7v for even less heat.


So I have done some IBT tests set to max, with extreme ticked for ten runs using all the ram. Results are very impressive. A max of 54C.

But perhaps even more impressive are the results of my same tests PASSIVE with no radiator cooling at all. (All cooling fans switched off except the 2x silent case fans to keep the Vregs cool.)

Still a max of 67C. Well happy. :)
