Core Ultra5 225h CPU machine test memtest86 randomly freeze

[C.C]

I have tested a set(2PCS) of 6400 32GB CSODIMM on different 4 platform
There are
1.NUC(CPU: Ultra5 225H)
2.MINI PC(CPU: Ultra5 225H)
3.CSODIMM Platform (CPU: Ultra5 235)
4.ECC CSODIMM Platform (CPU: Ultra5 235)

Using the Memtest pro version 11.5
When the set test on 1&2 machine , it freezes in randomly time (caused on 1 hour , 12 hour , 20 hour , not the same every time )
But the same set test on 3&4 machine, it can PASS 24 hour even more

Is it a known issue on arrow lake H cpu series? Or the set of CSODIMM are actually corrupted?

There are no known freezing issues on any current CPU (with the current software).

A freeze doesn't have to be bad RAM. Could be the CPU or motherboard. Could also be temperature related or BIOS settings.

Hello David,

I found that while the sets freeze on Ultra 5 225H machines, it always freeze on test 9
Did you have any suggestion that I can adjust on BIOS or test configuration of memtest?

You could try running the RAM at a slower speed.
