[SOLVED] Memtest86, when is it *reasonably* long enough?

[Steamy_Steve]

Ultimately I opted for a 128GB (4x32), 3600MHz, CL18 kit (not that I had much variety to pick from).
I've overclocked my i9 10900KF @5.0GHz, set the RAM profile to XMP II and started testing.

One hour of Prime95, first Small and then Large FFTs, showed no stability issues, with core temps ranging between ~72 and ~87 during the most demanding operations.

Thus I moved on to Memtest86. I had absolutely no idea it would've taken so loooooooong!! >0<
Exactly 14 hours and 30 minutes to run 3 complete passes.

Now, I've read that 3 passes with 0 errors is enough to deem a RAM kit 99.9% safe.
And long testing periods should stress the memory controller enough to decree its level of stability.

Would you say 14 hours and 30 minutes with 3 complete passes are enough?

Please, say it is.... -.-'

did you run the tests 1 stick at a time? Cause if you didn't and had got any errors, it would have been a waste of time , as you wouldn't know which stick is to blame.

Since you didn't get any errors, I would think thats long enough.

Yes, if you got 3x passes and zero errors, you're good.

I had to run 256GB memtests on my z420 and it took 38hrs for a single pass--and I had 3 sets of ram to test...took a whole week!
