RAM, CPU, or Motherboard Issue?

[erek]

I just put together an AMD Ryzen 9 3950X build with 2x16GB G.Skill DDR4 3600MHz 16-19-19-39 modules on an Asus ROG X570 Crosshair VIII Hero (Wi-Fi).

MemTest86 is consistently giving errors at the same starting Memory Address of 7641MB and usually CPU 24, but sometimes CPU 23. This is even at stock 2133 MHz or XMP Profile for 3600 MHz,

I tried both sticks individually and one stick did give an error on the same CPU 24, but only able to produce it once, very difficult to produce, took many tries, so with how difficult it is to produce on the one stick i am not certain the other stick is truly good or i just haven't tried for long enough to produce an error. I have no idea right now if it's the CPU, Motherboard or Ram.

I've gone through a lot of trial and error referenced at other forums:

Looks like bad RAM. But I didn't read all the posts on the other forums.

Go into the Memtest86 settings and select single threaded. Then it won't use Core 23/24. If you also get errors in single threaded, it makes it more likely the RAM is bad.

I ended up purchasing this kit for $57 in a pinch as it's on my motherboard's QVL @ https://www.bestbuy.com/site/corsair...?skuId=5822470

The Corsair @ 2133 passed.

Then also at XMP 3000 MHz profile it passed.

Hopefully can get back to 3600 MHz 2x16GB G.Skill kit after RMA. Thank you for the support and help so far

The replacement ram is stable so far @ XMP 3600 MHz
