Default Re: S775 Deliding (succesfull with delide die mate 2)

I had to delid half of my E7400s for testing the core, because the TIM was so bad that the CPU would thermalthrottle under load with 1,4V and NH-D14...
I actually never cared about using the delid die mate for 775 since the PCB is extremely sturdy compaded with skylake for example, but nice to see it can also be done with the tool from roman
I have noticed gains of about ~50MHz across the board on E7400s that didn't thermalthrottle before too, so definetly worth it for chips that aren't soldered (e1x00, e2xx0, e7x00 etc)
What I wouldn't advise is delidding C2Q CPUs, i have tried it on three dead Q6600 and one two I destroyed one of the DIEs...

Here a few of my delidding experiments: C2D E6300, Xeon E5335, Opteron 6128, Pentium D 820, Pentium E5300, Pentium E2160

IHS Removals, How to do it, Should I do it, and the Facts!

Found this list here of which chips are soldered.

Thanks, I should try my e6300's as well then.

It isn't really of any use for 65nm C2D CPUs, the E6300 was just delidded to show that it is possible...
There are no mesurable advantages from delidding soldered 775 CPUs... At least I couldn't find any

In the link I saw that there are not soldered e6300 versions. I will check which I have first.

As far as I know the L2 stepping E6300s are rather useless, all of my good chips and the top places on hwbot are B2, which is the soldererd stepping

Default Re: S775 Deliding (succesfull with delide die mate 2)

So I got my DDM2 today and tried to delid some 775 CPUs. Two dead E8400 all good and delid fine. Dead Pentium D = knocked a sliver of metal up off the delidded edge and breaks the tool.

Exactly what happened was: I put in the CPU and lined it up, tightened the screw with the allen key, kept going as it seemed rather stiff, stopped to find the delidding edge had started cutting across the top layer of the CPU - damaging both the IHS and itself.

To get it to work now I need to make a shim of kitchen towel and put it under the CPU.

It seems that some of the older CPUs are shorter than the CPUs this is designed for. So watch out with trying random CPUs.

Thanks for the input, I never tried any p4.
To bad that the tool is damaged.

Recently tried delidding some 775 CPUs, the new version of the tool works like a charm, even after 10+ beers.
However, did not notice any gain on Cedarmill. Had a CPU that used to run super hot (Celeron D 352 D0, soldered), thought delidding might help, but ended up getting same or worse clocks.

Huh, you had no issue with damage to the delidding edge when doing Pentium D/Celeron D?
