MemTest86 Pro v11.2 Reports Errors on Hygon 3430E Platform, but v10.2 Pro Passes.

[karry]

We are evaluating MemTest86 Pro on a Hygon platform and have observed inconsistent test results between two Pro versions.

Test Configuration
Platform: Hygon 3430E
Motherboard: [Please add motherboard model and BIOS version]
Memory: Samsung M425R1GB4BB0-CQKOL
Memory Configuration: SODIMMA1 + SODIMMB1
BIOS Settings: [Please add JEDEC/XMP/EXPO status, DRAM frequency, timings, voltage, and ECC on/off status]
Boot Mode: UEFI
MemTest86 Pro v10.2: Pass
MemTest86 Pro v11.2: Fail

Observed Behavior
With the same motherboard and the same set of memory modules, MemTest86 Pro v10.2 completes the test with no errors. However, MemTest86 Pro v11.2 reports memory errors under the same hardware configuration.

Questions
What are the main differences between MemTest86 Pro v10.2 and v11.2 that could affect test results, especially on x86 platforms such as Hygon?
When the two versions give different results, which version should be considered more authoritative for reliability validation?
Is the Hygon 3430E officially supported or validated in MemTest86 Pro v11.2?

Both these versions are old. V11.7 is the current release and V12 should be available in a few weeks.

You can find the full list of differences here. But there has been 100s of changes.

I don't know exact which changed impacted these results. (Or it might be not related to the version and be caused by some external effect, such as temperature).

They do look like real errors however. No reason to think the failure of the RAM is related to the CPU model.
