Hard system freeze and Memtest86 error with XMP on

[Gabriel S]

I own a 16 GB DDR4 memory kit produced by G.Skill (F4-2800C16Q-16GRK) and i recently enabled the XMP profile in the motherboard's UEFI settings (my motherboard model is Asus Rampage V Extreme). Soon after that, about a week later, i noticed the first hard PC freeze - no BSOD, no crash log, just screen and sound freeze, after which i had to do a hard reset. 2-3 days later, another crash. Until now i experienced about 4 crashes in about 2 weeks. I wasn't doing anything special - watching a video, running Visual Studio, or even leaving my PC idle.

I read that this kind of behaviour is usually caused by faulty hardware, especially RAM. I stress tested my CPU with Prime95 and all went fine. Then, i ran Memtest86 for about 1 day and i got 1 error in 8 passes (~20 hours).

My question is, should i be worried about this error? Is there a correlation between the freezes and the error found by Memtest86? As i said, XMP was enabled but i don't think this is something that should push my RAM beyond the manufacturer's limits. Would disabling XMP help, or does the error reveal an irreversible hardware fault in the memory modules which manifests itself regardless of XMP?

I would disable XMP, set the timings manually, and up the voltage to 1.22 volts and run memtest again. Since that is overclocked speed memory for that motherboard some tweaking could be needed even overclocking the processor some but the 1.22 Volts should fix you up.

So you're basically suggesting a manual alternative to XMP. If the RAM has faults, i expect this to fail again. I was under the impression that XMP was manufacturer-supported overclocking, so if the memory is physically fine then XMP should work without problems.

I think i'm going to disable XMP and any memory OC for the time being and see if the hard freeze problem persists.

You do see I said increase the voltage to 1.22 volts that is not XMP profile and should help stabilize the memory.
