10850k won’t overclock. Temps too high D15

[Lael Traylor]

OK. A little update. I have re-seated the cooler and the drop in temps is noticeable with the NT-2 paste. I have checked everything. Brought voltages right down. Running stable at 1.25 volts and set vcore to adaptive. All core is ratio 48 and io is 1.150v and SA 1.200v RAM is 2666 with an XMP of 3600. System is stable but under load the temps climb to 85. The Noctua doesn't have a plastic film on the underside of the cooler. I have screwed it down till you cannot screw it any more but with minimal effort. Meaning that I am screwing a half turn at a time until i hit that resistance and stop. So the CPU is not down to tight and the paste covering was good. I put slightly more on this time and spread it out again. The thermal difference is 2c under load.

What I did do today was stress the CPU with only 4gb of ram in Realbench and I got a max of 81c 10c lower than ever before. This got me thinking about the RAM and the heat its producing. DRAM is set to 1.35v which is stock but the MOS readout is 62.5c under load with a 16gb RAM stress under Realbench! Didn't check what is was with the 4gb stress. That got to be my heat issue.... Just don't know what to do to bring it down.

So these are my settings in bios. I cannot for the life of me understand how I am getting this kind of heat on an undervolt and stock settings. Someone please take a look and help me out.

Stock manual clock 4.8ghz RAM XMP 3600.

Idle
CPU core max 31c
CPU package max 31c
MOS 36c


Load
MOS 61.5c Under load 50% of ram (16gb) stress in Realbench
CPU core max 86c
CPU package max 86c

MOS 51c Under load 4gb Realbench stress test.
CPU core max 85c
CPU package max 85c

All of the above with the settings below. 1.25 volts isn't a lot but the HEAT... sheesh.
vcore reading 1.27v due to adaptive setting. I didn't want the cpu drawing 1.25 volts forever when it can be dropped when idle.

I can probably go lower on the vcore to further improve thermals but it’s in undervolt and I cannot see the point at this stage. Under normal work load video rendering at 1080p I hit high 50s over 3.5minute. It WAS hotter but the issue remains, not sure there isn’t a problem somewhere.
