enabeling xmp 1 or 2 causes my pc to fail booting

[Phoneas]

so when i try to enable xmp profile 1 or 2 or either do it treu the omen gaming hub. 
causes my pc to fail booting.
it does the memory training cycles but failes after a while and then comes to a standstill and i get the ram isseu beeping, 3long 2short.
i used to be able to have it enabled but i have probably been using the standard 4000mt/s for a looooong time without realising and recently realised i wasnt going at full speed.

i have ran multiple of the quick tests (non eufi)
i havent changed anything hardware related besides a extra ssd and a extra nvme ssd.

i have been keeping up to date with software and bios updates especialy after i have heard of the i9-13900 isseus.

Hi Phoneas

Since your system was working at full XMP speed before and nothing changed but software/BIOS updates, the latest BIOS firmware is almost certainly the culprit. HP's motherboard and BIOS combination is notoriously restrictive and sensitive to memory settings, often causing XMP profiles to fail after an update.

Here is a step-by-step troubleshooting plan based on the most effective fixes for this specific OMEN 45L problem:

Step 1: Perform a Full CMOS Reset

A simple BIOS reset (F9 in the BIOS) often isn't enough to clear the failed memory training data. You need to reset the CMOS (Complementary Metal-Oxide Semiconductor) completely.

1. Shut down the PC completely and unplug the power cord from the wall and the PC.

2. Open the PC case.

3. Locate the small, coin-shaped CMOS battery (CR2032) on the motherboard.

4. Carefully remove the battery.

5. Press and hold the power button on the front of the case for 15-30 seconds (this drains all residual power).

6. Re-insert the CMOS battery (or replace it if it's been several years).

7. Plug the power cord back in and boot the PC.

This forces the BIOS to completely re-read the RAM at its default JEDEC speed (4000 MT/s), which should allow you to boot without the beeping.

Step 2: Try XMP Profile 2 (Alternative Attempt)

Once you successfully boot at the default speed:

1. Enter the OMEN Setup Utility (BIOS) by repeatedly pressing F10 during startup.

2. Navigate to Advanced > Memory Overclocking.

3. If you have two XMP profiles, try enabling Profile 2 instead of Profile 1. Sometimes only one profile works after a BIOS update.

If this still fails, revert to the default JEDEC speed and proceed to the next step.

Step 3: BIOS Update/Rollback Consideration

Since the problem is likely tied to a BIOS update:

• Check for a Newer BIOS: First, check the official HP support page for your OMEN 45L GT22-1000i to see if a newer BIOS version has been released after the one that caused your issue. HP may have fixed the XMP stability in a patch.

• BIOS Rollback (Caution): If no newer BIOS is available, you may need to roll back to a previous BIOS version where XMP was stable. HP provides specific instructions for BIOS rollback, but this process carries a small risk, so it should be a last resort.

The fact that you were running fine at a higher speed before and now cannot enable XMP after updates strongly points to HP restricting the memory profiles in a firmware release, which is a known pattern.

 Step 4: Component Isolation Test

The 3-2 beep code is a memory failure, so we must rule out a physical hardware issue (even though it's less likely than a BIOS conflict).

1. Repeat the CMOS Reset (Step 1).

2. Test one RAM stick at a time:

   • Remove all but one RAM stick.

   • Place that single stick in the slot designated as Primary (usually DIMM 1—check your motherboard manual).

   • Try to boot and enable XMP. If it works, test the other stick in the same primary slot.

   • If a specific stick fails, that memory module is faulty. If both sticks fail XMP individually, the motherboard or CPU's memory controller is the problem.

Given your full system failure and the XMP issue, the most common solution on HP OMEN systems is a successful CMOS reset combined with finding the specific XMP profile that a finicky BIOS will accept.

This video addresses the general issue of XMP failure on an OMEN 45L, which is highly relevant to your beeping and failed boot problem: OMEN 45L XMP fail.

I hope the above is helpful
