Hammer test note in memtest86

I’m getting a note in memtest86 on GSkill 5600 ddr5 cas36. Says something about errors may occur but not definite. I found the following at memtest86 website: *


*Starting from MemTest86 v6.2, the user may see a warning indicating that the RAM may be vulnerable to high frequency row hammer bit flips. This warning appears when errors are detected during the first pass (maximum hammer rate) but no errors are detected during the second pass (lower hammer rate).*

Any thoughts on this?? Thanks.***

Hmm, I'm seeing 56 - 58°C with two sticks, at VDD 1.35 and VDDQ 1.3575, erm. are these okay temps for DDR5? For cl36 and 6000 MHz. No errors in 6th run so far
second full run.

Okay guys, so, I'm somewhat confident, that higher voltage completely removed all errors, and I also found ideal voltage for "okay" temperatures. I've ran MemTest for 3 times, all 4 test runs each, so 12 test runs alltogether.

So my final config is VDD 1.35 and VDDQ 1.375 aaand...everything else is vanilla XMP I.

Thank You guys once more!

I'll update the topic, when I'll test 4 memory sticks, another two should arrive on friday, so I'll test it during weekend.

Thank You Hopper64 and Shamino once more! [I mean, guys, there's load of settings in memory settings on Z690, I'd never figure to modify VDD and VDDQ by myself, not a chance].

Just an fyi, if you insert a usb stick you can take screenshots in your bios. And you can keep up with the latest Shamino bios here, https://www.overclock.net/threads/official-asus-strix-maximus-z690-owners-thread.1794802/
