I was jealous of some of the thermal results I kept seeing on here and decided to redo my thermal paste to see if it helped. Immediately when I pulled my NH-D15 off, I noticed a substantial gap in the thermal paste residue on the CPU. Tested with RealBench 2.56 for 15m using up to 32GB RAM before and after. Peak CPU Package temp dropped 4°C.
This is with my previously established stable settings. 1.32v VCORE, cache 43x. Per-core OC with 1-7 set to 50x and 8 set to 47x. AVX offset of 2. C1 and C3 left on, as per-core OC seemed to be broken without them on in previous testing (though there's been a BIOS update since then, so I don't know if that changed anything). I always get SpeedStep, EIST, and SpeedShift mixed up, but if memory serves, only the one required for c-states is enabled. I didn't go back into the BIOS to verify settings.
I also ran the Blender BMW benchmark and I no longer experience thermal throttling on any cores in that now. Now I'm wondering if I might have the thermal headroom to push an all-core OC of 5GHz.
I'd love to get any feedback anyone has - particulary
, as you really seem to know your stuff.
*edit* UPDATE: I set my OC to 5GHz all-core with no AVX offset. Was able to complete the Blender BMW benchmark with a max core temp of 97ºC. Running OCCT on default settings for a bit and might do some additional stability testing, but it's looking good so far.
*edit2* Nope. Small FFTs in P95 26.6 thermal throttled and BSODed with WHEA_UNCORRECTABLE_ERROR.
