Question ASUS Prime X570-P USB boot confusion

[Hugo]

I built a machine two years ago on on this mobo.

Ever since then I'd get an ocassional crash, like sometime weeks apart, sometimes days apart, I suspect a memory issue so want to run an exhaustive memory test.

I have 128GB of this (4 sticks) the board is not being overclocked.

But I created the memory stick based USB boot device with so that the machine can boot from it with memtest86 but cannot get the machine to boot from the USB device.

I'm not an expert on these modern BIOSes and wondered if anyone here uses this mobo and can help?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

XMP isn't enabled in BIOS?

Hi,

Well I managed to get the memtest to boot from a USB drive and it ran for 18 hours and passed all tests.

So I now wonder what might be the cause of the crashing, here's the full list of components (its a picture of my Amazon order list but appears as a giant X here - why?).

I ordered more memory once machine was running so the total memory is four sticks not just the two in the order below.

I also bought an additional SSD:

SAMSUNG 980 PRO SSD 2TB PCIe NVMe Gen 4 Gaming M.2 Internal Solid State Drive Memory Card, Maximum Speed, Thermal Control MZ-V8P2T0B/AM

The video card is this one

GIGABYTE PNY GeForce RTX 3060 Ti 8GB XLR8 Gaming Revel Epic-X RGB Dual Fan Graphics Card LHR​

OS is Windows 11 Pro. ​

I'm going to grab the windows kernel debugger and take a peek at the most recent dump file...

So I now wonder what might be the cause of the crashing,

What programs are you running when the system crashes? I had problems with Topaz Video AI on my Asus X670-P Pro WiFi back in January 2023 and "cured" the problem by limiting my 3060 to 95% power in MSI Afterburner. Topaz eventually issued a stable update and I now run a 4070 at full power during video renders.

Since your system is two years old, I'd try a fresh install of Windows on a different SSD and see what happens. Even a cheap 250GB SATA SSD should be enough to see if your existing OS is going bad, or you have a real hardware problem.

If the new SSD fails, try pulling two sticks of RAM. Despite passing MemTest86 (one run?) some people recommend several complete passes just to make sure. At 18 hours per test, you probably won't want to do this.
