Hello.
My system is vulnerable to row hammer during memtest86 test, I've read there's a way to fix this without change hardware:
https://en.wikipedia.org/wiki/Row_hammer#Mitigation
A less effective solution is to introduce more frequent memory refreshing, with the refresh intervals shorter than the usual 64 ms, but this technique results in higher power consumption and increased processing overhead
I looked into my Gigabyte-Z77X-ud3h BIOS, there's tons of memory timing settings, but no one is currently at "64", could anyone tell me which value should I change?
Thanks.

Just looked through the manual regarding bios settings for memory, unfortunately refresh interval or refresh rate was not listed. So, according to Gigabyte you cannot change that setting.

Just because I'm curious to learn, how does row hammer effect a system?
