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 on a quick double run on Max settings. results are almost identical. Pleased? Oh yes! Now for some more volts and clocks! Pictures to follow. just uploading.
