4.4ghz was my max before delid,
4.5ghz prime hit 105C within seconds,
after delid, i could run 4.8ghz easy, 76C hottest core after 24H prime ..lol

Hokies: no need to worry, Val probably killed it for doing more than 1.6v on air....1.9 is TOO much, you need sub zero temps for that, heck it's even more than max dice (-78c) vcore!!!
Also, another way to instakill it would be to push over 1.35v vtt/imc volts on air, at least it would degrade the imc in no time.

Using up to 1.7v on dram and 1.2v/1.15v vtt/imc is plenty for benching modern sticks and REALLY safe.

As you wish though, it's your gear. wink.gif

I only had 1.98 vcore pumping in along with 1.15 vtt imc and 1.75 dram. Then he got tired lol

Well I didn't kill my chip. I don't think I did the best job though. I think I was a little heavy on the Formula 7 on top and inbetween. That stuff is hard to spread!

Anyway I did shave a few temps and I got the lid off without killing the CPU. Here's some results. I will order some Coolabs Pro soon...

BEFORE


AFTER


As you can see, 7C drop in temps. Which is better than nothing, but I think I could improve with a better paste application and just better paste period. Also I didn't quite get all the glue off, I got enough so the IHS could move freely though.

holy moly....that's a lot of volts -> you electrocuted Franky!!! aaskull.gif

but he died in the name of OC science and knowledge......few who knew Franky will forget his sacrifice.....brave brave Franky.....redface.gif

What you need to do to get the big temp drops is use CL PRO or CL Ultra. We see this happen often with attempts at other otherwise fine TIMS as they just don't do this job well.

I'd suggest trying some CL PRO or Ultra to see.

Also, might be concave IHS - which is only fixed through lapping the IHS - but can gain ~10C if it is the problem...

Well one benefit is it seems to scale well at higher voltages. I got 4.6ghz running IBT right now on 1.41v and the temps are in the high 70s. I was in the mid 70s at 4.4 & 1.32v before delid.

That might get too hot, i hit 80C doing 1.42v (1.41v wasnt completely stable)

I'll try it in a few minutes.
