Background
I've just upgraded to 4GB of RAM (from 2GB) (for Win7
) and have found that my old OC is no longer stable.
With just 2GB it was stable (24hrs+ Orthos Blend test) running as in sig (10*300 @ 1.5v with RAM at 450Mhz 4-4-4-12 @ 2.1v). But with the addition of another 2GB of ram its no longer stable.
Memtest showed that the new RAM (same as old RAM - orange GeIL PC6400) wasn't stable above 420Mhz (2.1v), so i reduced the OC to: 11*267 @ 1.4v and changed the ratio so the RAM was running at its stock 400 Mhz (still at 2.1v).
Problem
Running ORTHOS small FFTs CPU test at 11*267 with 1.4v runs for at least 33hrs.
But if i run the Blend CPU and RAM test ORTHOS has been crashing after a few hours.
So, I'm assuming the problem is something to do with the RAM.
Should I:
A) Loosen the timings on the RAM (currently at 4-4-4-12)
B) Increase voltages in the BIOS (suggestions please on which might sort it out. NB? FSB? something else?)
