10980XE not quite right

[13oots2]

I just bought a second 10980XE and popped it in my Asrock Fatal1ty X299 Professional Gaming i9 XE, it won't turbo boost and uses the same 4 cores as the first CPU as preferred cores, it actually drops the frequency rather than boosting it. It tests out fine and overclocks to 4.6 on all cores and passes Intel Processor Diagnostic tool just fine, has my mobo somehow remembered the previous CPU? If this is the case will reset the board when my new water block arrives and go from there, I have about 25 days to return the CPU.

Update your bios to latest version and let it reset everything to defaults then test.

Am already on latest BIOS and had tried resetting. Will physically remove the CPU and reset BIOS when the new block arrives next week, also I will pull the battery and see what happens.

Yes it is possible the bios thinks it's the same cpu as its the same model and stepping. So it's just not reset fully. I think clearing the cmos should work.

I did everything I could think of, reset while CPU was out, take battery out and left for 10 minutes. Am beginning to think against all odds, my second CPU has same preferred cores, all is stable at all core 4.6.

Its possible I guess. Although it sounds unlikely. Maybe you need a another board to test it in

I will put my 7940X in and see what happens after I reinstall the 10980XE, that should clear any CPU if it is being remembered by the Asrock.

good idea. let us know how it goes.

I tried with the 7940X and then cleared everything, still the same preferred cores with the new 10980XE. It's a better CPU than my other one for ocing, so will stick with it.
