Because you only have one stick and can't try another, I suggest using a bootable utility such as memtest86 to check your RAM. I faced a similar issue where the system would freeze only during games, and the fault was a faulty RAM module. I’m not comfortable with rebar, but it’s likely that the problem involves different RAM sections being accessed depending on whether rebar is active or not—like gaming mode versus normal use. Let me know if you haven’t used diagnostic tools before. If you’ve ever installed Windows from scratch, it’s similar except instead of installing software you’re starting a diagnostic process.
If running your RAM doesn't meet the manufacturer's specifications (xmp), the RAM module or CPU controller might be faulty. Sometimes the problem lies with Windows 11 installation itself. Before attempting any hardware repairs (RMA), try a clean install of Windows 11. If you lack another backup SSD or HDD, create a full OS backup on an external drive so you can revert if needed. Avoid using Windows reset tools—they’re ineffective. Instead, use the ISO/Media creation utility to wipe everything. Disconnect other drives before reinstalling Windows to prevent accidental data loss.
I don't have a defined system specification for starters. Could you clarify what you mean by "full system specs"?
Do you know how to make bootable USB drives? The official guide and a video walkthrough are available at the provided link. Follow these steps: download the Windows MemTest86 USB image, right-click it and choose "Extract to Here," placing the file in your current folder. Launch the included imageUSB tool, which should already have the image selected. Select the USB drive you want to use as a bootable one—be aware this will wipe all data on that drive.
Rebar shouldn't affect crash rates unless activated. It can allocate a chunk of RAM for bulk data transfers to the graphics card at once, rather than transferring smaller sizes repeatedly. XMP settings may trigger crashes because they change RAM parameters—without it, it runs at standard frequencies and voltages. Enabling XMP can push RAM to higher speeds (like 3600 MHz) which might cause instability if it becomes too unstable. Use MemTest to check for errors. If issues persist, try lowering the frequency to 3200 or 3000 MHz and retest. Consider testing in a different memory slot to eliminate hardware or environmental factors.
The issue is the RAM speed isn't 3600 MT/s—it's actually 3440 MT/s, which might still be sufficient to cause a system crash.
