The x299e-itx/ac had BIOS 1.50 released on Mar 2nd.

I flashed as it contained fixes for Skylake CPU. I've done zero benchmarking, so I can't give you any hard numbers, but if there's been a performance drop off, I haven't noticed.

Also, my system was stable before... No reboots or crashes.

This microcode for skylake CPUs lowered their VCore settings. My idle temps on the CPU were in the 42-46C range, and VCore was at 1.126V. Much too hot for my liking. I was even considering a repaste last weekend. After the flash, idling at 32-34C with 1.066VCore on the CPU

What a difference a flash makes!

Thank you for that. 

My 7800x idles at 23-29c, and when I (factory) OC a tad (from base 3.5 to 4.1), I idle at almost identical numbers. 25-30c. 

Under full load (I crunch for SETI using BOINC every night), this CPU hits around 49-50c. Under full load WITH OC to 4.1, it hits about 65c. 

Is the x299e-itx/ac board using the same microcode as the base x299 chipset? ie my x299 TaiChi will receive the same base code as your x299? Do you happen to know? I still have not flashed to 2.00, and am still sitting on the fence about RMA'ing this board for one without the 4k BluRay playback limitation.

Unfortunately, I'm not an expert, but here's what we do know:


X299 Taichi - version 2.00, release 2018/3/2, size 11.58MB
"Update Skylake-X CPU Microcode to revision 43 and Kabylake-X CPU Microcode revision to 84. (For CPU security update)"


X299E-ITX/ac - version 1.50, release 2018/3/2, size 11.16MB
"Update Skylake-X CPU Microcode to revision 43. (For CPU security update)"

----------------

They were released same day, and have same Skylake-X Microcode for revision 43. Does that help any with the decision to flash?

Well, I haven't heard any screams of pain just yet. I dont see people panicking anywhere, so maybe I'll just flip a coin. ;)

It's a two pronged fix for Spectre and Meltdown.

1) You'll want to run a BIOS/UEFI update which will update a bug found in Intel Management Engine. See more info here - https://www.bleepingcomputer.com/news/security/intel-fixes-critical-bugs-in-management-engine-its-secret-cpu-on-chip/

2) Next, you'll need OS level patches from your operating systems provider which tackles some of the Meltdown/Spectre related bugs. See here for more info - https://www.extremetech.com/computing/265676-microsoft-now-distributing-intel-microcode-updates-spectre-meltdown-improves-antivirus-compatibility

I also think the Intel ME drivers have been updated too, but not sure if that comes in the OS level patches or if you need to do that extra.

Some internet searching on Spectre/Meltdown protection ( for example on windows https://support.microsoft.com/en-gb/help/4073119/protect-against-speculative-execution-side-channel-vulnerabilities-in or https://www.howtogeek.com/338801/how-to-check-if-your-pc-is-protected-against-meltdown-and-spectre/ ) will let you know if the system has been patched.
