Asus Rampage V Edition 10, sync all cores to 40 not applying once in Windows.

Hi guys.

Decided to do a total clean install on one of my rigs last night, everything appears to be working just great but one little annoying problem I'm having is syncing all cores to 40 in bios doesn't appear to be sticking once in Windows. Only one of my cores is hitting 4ghz yet all the others are stuck on 3.5ghz.

I've flashed the bios to the latest non beta version (1903)
Checked all power saving settings
Gone over all of my overclock settings etc

Any ideas why all my cores aren't syncing to 40 (or any number I chose ie 38, 39, 42)? I've joined up at Asus ROG Forum @Silent_Scone looking for some help, but in the mean time until my account gets verified over there for posting, I thought I'd ask here. I can't see it being anything to do with how I've altered the bios as this isn't exactly a punishing overclock, just wondering if I've forgot something obvious.

Basic things I've set for the overclock

CPU core Voltage - 1.20
Cache Voltage - 1.15
Input Voltage - 1.8
CPU LLC - 6
AVX offset - 3
Cache Ratio - 3.4
XMP 3200
RAM voltage - 1.35

Hello,

seeing as reinstalling Windows is the only real factor here, I would say it's likely a microcode issue. You can try uninstalling KB4100347 as this contains the afflicted ucode. X99 is a fairly old platform now, so I'm not sure what ucode is in 1903 UEFI without investigating further.

Thanks. I did actually try and locate that one but couldn't find it in the windows updates. Is there a way to really dial in to where I can find that if it's not showing on the recent updates or add remove programs?

mcupdate_genuineintel.dll

mcupdate_authenticamd.dll

if the only thing you changed is windows install than I'd assume its a windows thing.. but now you changed your bios as well .. that opens another can of worms ...
I noticed a lot of slowdown after all those patches for intel when i had 5820k.. that was the main reason i sold my X99 platform.
Now I can't hit the same CPU scores in 3dmark on my 8700k i was hitting a year ago..

so i would say intel updates have a lot to do with that...

Yep, im getting nothing but issues on this X99 platform now. I've three huge issues. This is the least of them. The other two are actually far worse problems, one is stopping the system booting with USB devices plugged in. The other is a problem with triple screen surround but these aren't problems for discussing here. What a terrible platform it's turned into.

Did it work ? and its not x99 that's the problem as such , Haswell-e cpus work just fine , Broadwell-e cpus seem to be the achilleas heel when paired with x99 these days as every update seems to break the microcode in one way or another.

It most certainly did darket thank you. I gotta apologise, for not thanking you last week.
