I have noticed RGB lighting on I can hear much more noise/whine verse disabled/off on most MB. Not saying it is the lighting just something I have noticed.

901 is best for DR b die. Bios ffter 901 you will need to set vddq manually to 1.35 to 1.4v to boot in the 4000+ range.

The only reason I would run newer bios than 901 is if on KS you need it as...

If you have tried all of that and it is still having issues you can either lower clocks until stable or return. Pretty unlikely any bios update is going to fix it.

I have 2 Apex 1 will run 6400...

Post has been deleted but can be found on other sites.

Hmm I have 2 12900kf cpus that i have used in z690 Strix d4 and z690 Apex and they work.

I have has that issues at times in Strix d4 where it stays on white led and monitor screen is black. What I...

Hmm I have 2 12900kf cpus that i have used in z690 Strix d4 and z690 Apex. I have has that issues at times in Strix d4 where it stays on white led. What I did to solve was turn off psu. Then hold...

I have seen some benches from a couple people and so far from what I have seen if you have a...

No different than updating. Use Ez Flash in bios or Flashback and you can go back to older bios.

You are not suppose to use old CMO files on new bioses. This has been a best practice forever as far as I know. It usually works using old cmo files but it can cause issues and is nothing new.

I have never had that happen with a bios update but I have had to reactivatee when switching MB or hardware. I used the phone activation to get it activated again.

I used the method were they send...

On Apex and 1302 is good for me.

If you have an Apex and slot 1/chA clocks(is stable) say 400 to 600mhz lower it is the MB most likely. Been confirmed by many. I have old board and new 2022 manufacture date and new board is night...

As far as I know 16gb ddr5 dims are SR.

You can look at memtweakit on the last page at the RTLs and there will only be 1 for each channel if single rank.

Edit i was thinking of DDR4 for the...

Have you tried 1 stick at a time. I see quite a few reports or slot b/2 clocking higher. I would try that to see if dim 2 is stable at say 6000 or 6200 and then test what slot 1 can do. If so there...

Hmm try removing the power strip from the system or at the least plug the pc directly into the wall to eliminate it as a variable. That is what I would do anyway. You can leave your peripherals...

What did they do to test it? What programs did they use or how did they test it or didnt tell you?

With 12th gen I have seen it can pass all kinds of different stability, memtests and bench test...

If the memory doesnt have more than 1 xmp profile it wont show. Has nothing to do with MB it is memory kit and vendor specific.

I posted link to screenshots with kits that show multiple profile on...

The XMP 3.0 profiles are up to the memory vendor as far as I know. I see users on Asus with certain vendors show more than 1 profile

Just use manual v core in bios. Leave turbo boost on.

I dont quite understand what you want to do but if you want fixed/static vcore that is what you do.

Note if using Sync all cache will stay...

Using the defaults bios settings is an OC on the CPU, by default it set MCE to enabled. Set MCE to disabled and then it might run prime95 as it will follow Intel specs.

Also run hwinfo64 while...

It is probably when it gets to testing small fft with avx that causes too much heat. It depends on how you have the bios set for power limits/temps etc. Few 10900k will be able to run small ffts at...

I take you have it in a case and side panel on. Otherwise you can set FlexKey option in bios under tools to boot to bios/safeboot when presssed.

I dont have a z690 ddr5 board just going by memory...

So go back to an older bios. I have tested them all and they are about the same for me but I set all timings manually.

If an older bios performed better why not use it?

Did you try bios 1001?...

I had to set static v core 1.36v in bios to run 52 all core or to boost 54 to 55 on multiple cores.

Cant complain though with 4133c15 DR b die.

If I run the CPU at default clocks or MCE auto...
