PC 12th Gen intel won’t post w XMP enabled.

[TheK9]

So all my parts just came in for my new build,
Here is the parts list with pc part picker, so I

don’t have to manually list them all pc specs.

OS: Windows 11 Pro: Build 22000

Anyway, I have 4x16gb =64gb of ddr4 3600mhz cl18 ram. When I boot the pc it works fine, if XMP isn’t enabled, but of course I only run at 1700mhz or so… So I went into the bios and enabled XMP for the ram, with XMP enabled the system will not post and a cmos reset is required. In an effort to figure out the issue, I tried the following. Removed new ram, and added my 4x8 = 32gbddr4 3600 cl18. Pc booted, then tried xmp for these sticks, it worked. Powered down, tried two sticks of the 4x16, so 2x16. It booted fine, so then I tried enabling xmp for just these two sticks, and pc booted fine. Added the other 2, and re-enabled xmp, won’t post. Okay, so clearly 64gb of 3600 is causing the issue. So I updated my bios and tried everything once again, same results. I then searched for beta bios for my motherboard on MSI forums and tried with this bios to see if maybe compatibility was improved, no luck still no post. So, I’m out of ideas, is there anything I can do? What is my best course of action? Return the ram? Motherboard? Both? Is this a I9-12900k cpu limitation? A motherboard limitation? Both? Or a ram issue? I’m really just looking for guidance on how to proceed, I’ve spent a fortune on this pc already, and I’m just incredibly stressed that it doesn’t run smoothly, and want a hopefully simplistic course of action. Thank you for your time.

EDIT: the 4x16 kit works with xmp enabled on my old system with a i9-9900k asus hero XI Maximus motherboard.

Add a 100mv or so to the voltage that will likely get you there. I run an i9 12900k with 4000MHz C18 and XMP works fine but I have heard others struggle on various generations and a small overvolt is a cure I have seen.

Hey, I just enabled Gear 2 in bios: I am unsure what this does, but the pc booted. Is gear 2 bad? If so I will try increasing the voltage as you suggested.

Gear 2 is a good shout. If set to auto, memory of that speed should be set to gear 2 anyway, but often forcing a setting yields better results. Does it work now?
