Memtest86 a poor indicator of memory stability?

[joeyjojo]

Hi all,

Opty 148, 2x512 kingston value ram, dfi lanparty expert
I was just playing with the crappy ram mentioned above. With the htt at 255, I thought I'd see if it was stable at a 9/10 divider (yeh I know, unlikely conisdering its value pc3200). Anyway, booted memtest86 from cd and left it for an hour with no errors. Loaded up windows and it wasnt stable (flickering screen, failed superpi and p95 etc). Tried looser timings and more volts, memtest still thought it was stable but windows clearly wasnt.

Wierd that memtest, which is meant to be a reliable indicator of stability didnt detect any errors. Any thoughts?

Is the CPU being overclocked also? (255HTT?).

Yeah, opty 148 @ 255x11 1.45V
Im pretty sure its not the cpu though

Isteresting guys, thanks

It can be. Depends on the strength of the controller but usually a bit more vcore sorts it.

Btw, what is a sensible vcore for a 148 with storm waterblock and 120.2? I thought about 1.6 was the max for good water
