So unlucky.
You did everything correct, and seen not much of an improvement
I did one thing wrong, seen a huge improvement, but damaged my CPU...

We were both unlucky in that respect.

Very nice bro!

Thought to show you my temp difference:
OK this is 60hrs vs 7hrs folding - but the temps never really changed that much within the 60hrs:
Before delidding with MX2 temps: 85-92

Current MX2 temps after de-liodding: 76-82

TD,
Your core 0 is 4c hotter than your core 1 now, that does not look right. Are you sure the cooler is making good contact? Changing mine around is what got me from a 10c improvement to a 15c, and that was just repositioning the cooler, I didn't do anything to the ihs.

sometimes the core 0 is hotter thanks to the igpu right above it since it dissipates heat from both. but it's up in the air with every chip.

I thinks its quite normal . I get 75 ,80,80 ,77 at 5.1 Ghz

No just an oldman is correct - that's due to my reduced pressure mounting of the Antec 920 - and also due to my not so even paste application. I was more in a rush when doing the paste, as I know I'm going to open it up again.

My friend just came in and made a very valid point:
Lacquer the PCB.

Would that be advised and/or how could I protect the die from not being lacquered as it is a spray.

its normal to have a temp difference between cores, even after delid,
when its still 12-16C after delid , you should be worried,
anything between 4-8C temp difference is normal..gets bigger under load, and higher oc's

tape of the die and the underside pcb if possible, and anything copper on the pcb..
i wouldnt do it, but thats upto you of course smile.gif
you could spray some of the laque onto something, dap it and dap the copper you nicked on the pcb..

i wouldnt call 15C not much of a improvement TD smile.gif

at least you have got a good temp difference now justanoldman, 15C isnt that bad really..gratz smile.gif

Lapping:

600 Grit Dry

1500 Grit Dry
2000 Grit Dry
2500 Grit Dry
2500 Grit Wet

It should be noted that when running Prime95, depending upon the CPU speed, around the 17 to 19 minute mark, one core would spike to it maximum temperatures of 68C but did not stay there. The remaining three cores also spiked to their highest temperature during the stress test, but did not stay there. The average temperatures for each core using the Excel log from Real Temp after running Prime95 for 20 hours were, as follows: 53.66, 61.66, 58.68, 61.42.

In my opinion, the average core temperatures over an extended period of time is more indicative of the CPU’s operating temperature, rather than an anomalous spike in the maximum core temperatures.

The Intel Burn Test was run at both standard and maximum. There was no difference in the m
aximum temperature for each test.

My point is that I don't see anyone else with a core0 of 4c hotter than core1. Before delid he had relatively normal distribution.

I am not talking about general differences between cores, I am saying he can't go from core0 being 6c less than core1 to after delid of 4c over without something being amiss. That is a 10c swing, and core0 should be less than core1.

Hopefully when he redoes it things will look better.

? As long as cores are with in 5-6c of each other under load that is 100% normal i do not see the issue here?

my temps between cores are 4c- 6c max spread between cores coolabs pro on die. the only tim that should be put on die when deliding any other tim is pointless. (coolabs pro / ultra) biggrin.gif
