maximus xi hero -i5-9600k & xmp trouble

[Puter]

maximus xi hero wifi ,i5-9600k . i enabled xmp in bios , & overclocked in windows with Intel(R) Extreme Tuning Utility V6.4.1.205, i tried defaults in ixtu, to go back to cpu defaults but with no luck , cpu stays at 43x all cores ,will not go any higher but will go lower,if i disable xmp in bios boot into windows it locks up then a lot of bsods .when i go back into bios & enable xmp,it boots fine in windows no bsods nothing , i've called intel ,talked to asus , no answers , i don't know what to do,ive done alot of research on this found out xmp raises the voltage on cpu therefore overclocking cpu, also cleared cmos many many times but i always did enable each time enable xmp , i know better now , it took all of this to find out the hard way
thank you so much , Tony

I think your misunderstanding a few things Tony.

Your 3200MHz RAM would default to 2400-2666MHz initially as 3200MHz is beyond the JDEC standard and therefore you will have to manually enter your SPD in Bios to get them to their rated frequency as XMP would not work. XMP (Extended memory profile) capable ram is up to 2666MHz.
You also have separate voltage control for RAM and CPU.
I also recommend only changing Bios values in Bios and not via a third party Windows app as you can corrupt your Bios this way.
I also recommend you update Bios to latest version if not already done so.

Your RAM indicates 2x sets of 16GB which can cause issues and you could have a mismatch due to Latency differences during manufacture. Initially just use one matching kit to check for stability then add the second kit. They may work together but no guarantee.

i done everything ya said , updated bioes , made shore all 4 sticks of mem are stable,in bioes save default settings , & still all cores at 43x cannot get to cpu defalts









thank you very much it worked thank you

Go into your Bios>Extreme Tweaker menu>AI overclock Tuner and set to manual. This will allow you to change your multiplier.
You can bring your Bios back to default by removing the MB CMOS battery for 10mins. That would default to 3.6GHz.

thank you ever so much it worked
