Ivy Bridge chips SUCK under Phase

post #1 of 27
Thread Starter 
The 3770K to be clear. Phase unit is showing -40C at the Evap while the CPU hits 40C after 140 seconds of wPrime at 5.2GHz 1.6V.

None of my previous chips have been like this, neither my 1090T or FX 8120 (Only had for a couple of days).

There's no issue with short benchmarks as it hasn't got enough time to heat up and stays far below 0C.

The only fix would be to delid the CPU, running IHS less with liquid metal TIM would most likely improve things further too.

It's the same under water too, under load I'm hitting 92C with apparently very little heat dump into the loop.

Here's the setup:

Also everyone likes a frosty Evap!

Here's a poor 5.5GHz CPUz, I only took it because I needed something to show for 20 minutes of Phase.

Think I need some more insulation here! This turns to water once you get going so make sure to put a cloth here to soak it up.

It's only a 77W CPU. Phase unit was under much more load with my old 1090T and FX8120. The Evap didn't drop under -40C when the other chips would drop it to -20C if under load long enough.

The issue is the thermal paste.

Unless it's an 1155 980X I'm okay!

(Yes, I know the 980X isn't 1155, it's a joke)

I'd say try a delid..I got 5700 out of a delidded 3570K on DICE..It never got hot..That's just all it would do sad-smiley-002.gif pretty sure all the 3770Ks are binned higher..You should get moar out of it than that...even if it's an outer-wafer chip..which I doubt..I think they made all those the 3570Ks rolleyes.gif

This is my second 3770K, I damaged the die of the last one.

Note the corner:

I probably won't do this one.
