I got an answer from Intel and the problem will come from the Asus bios and therefore Asus has to solve the problem
In other words, it will never be done

I expected ASUS X299 Bios Team lead by Shamino trying hard to getting best solutions Master Tistou77, They’re increases UNCORE speed from default 2.4GHz to 2.7GHz by default for performance gainers over other vendors. Thus something over default under Spectre and Meltdown patched may cause those issues.*

Confirmed. I had the same problem on Windows 7 (x64) i9-7960X/R6E and BIOS 1603/1503mod. After the update, Tj Max set to 110°C and cores temperatures have increased by ~5/6°C (idle and full load). No way to fix it? Thanks!

The only fixes are....

1. We don't know if it's actually increasing the temp or just reporting it wrong.
2. Stay on 1503 with microcode 43. If you're running Windows 10 1809, Windows will load microcode 49 automatically and the temps will be fine.
3. If you want the other updates in the 1603 BIOS, but not the temperature issue. Download a modded BIOS with microcode 49 or below, anything
above 49 will show the temp increase.

All above maybe came from this cause.

1. 0200004D microcode was issues to address most 2018 vulnerable include Lazy FP and L1TF by early stage patch.
As I said many time here those vulnerables need both hardware and software especially OS Optimized together to
mitigation in better shape. Compared to cars engine used emergency mode on ECU to avoid many parts failure thus *
these mode consume more petrols than default. But it save the engine and part lifespan not shorten lifespan.

Idle temp increase around 5-6 degree Celsius was not seriously situation for CPU itself at all . In terms of these
for me did not disappoint solutions at all.

2. Following 0200004D there are 02000050 and now 02000055 which I used for testing with W10 2019 18298.1000.
There are many area that improve over 0200004D especially AVX2/FMA3 heavy loaded and AVX512/FMA3 loaded
CPU was more efficiently to run full 100% load under 55 degrees Celsius. (Lower than pre mitigation microcode a lot ).

3. Idle state increased around 5-6 degree and full load below 55 degree Celsius didn’t harmful or shorten your CPU life at all.

From 1-3 l’d like to say intel trying to do their best solution for vulnerable mitigation. Hope you all don’t be panic on Idle temp *increased*
and enjoy your CPU performance. Cheerful.*
