Checking RAM stability

[MyLittleFella]

Hello everyone.

Recently I changed the original HyperX heatsink for a white one I bought online. It's very easy to change it w/ the help of a guitar pick and a hair dryer. Everything went fine.

I installed the ram module back on the mobo and booted my pc. Everything ok for the last 3 days. But a few hours ago I was playing GRID 2019 and while it was loading a race the PC has frozen. Had to press the reboot button.

On the other hand, everything on my pc is behaving normally, haven't felt it different at all.

That being said, I want to make sure 100% that everything is fine. I'm gonna leave Prime95 running overnight till tomorrow (monday) and then memtest86+ from monday to tuesday. Both are gonna last for +- 6 hours. (Which is +- my sleep time).
 

Question: are both of these tests safe to run overnight? If both of them show no errors, that means I'm ok?

It's almost summer where I live so air-conditioner is always on in my room and I have a closed-loop WC. All my specs are in my bio.

Thanks!

I think 1 full loop of Memtest86 should show errors if the RAM is defective ... but if voltage is not extreme the 6 hours should prove more certainly.

"Heatsinks" on ram are mostly for show.

Hmmm, I see.

Actually did a bit of searching, there are occasions where errors are found after 10+ loops, but that is very rare.

Yeah I imagine. Either way, I guess i'm gonna do a try

I'll do the test this night and let you guys know the results tomorow, for those who are curious
