Hi guys,
I have an odd problem which I would really appreciate some advice on. This has been an ongoing problem which I've had for some time and have really struggled to pinpoint to any component.
I have a PC of spec as in my sig, altho the CPU is new - I used to have a Venice 3000+ E6 rev but the problem is identical regardless of which CPU I use. Whilst using the Venice, it was overclocked to 2.66Ghz (295x9) with the RAM on a 1:1 (590Mhz) @ 2.5-4-4-8. This is within the rated spec for Geil One RAM (606Mhz @ 2.5-4-4-8).
The problem manifested itself as instability initially. Over time, I kept clocking back until I was at stock and still experiencing instability. I sought help from here and another highly respected forum run by the mobo manufacturer. I tried all sorts with the very limited resources that I have (nobody I know that lives near to me has s939
).
I know believe that the RAM is to blame for my instability. The long and the short of it is that I can't run CAS 2.5, but CAS 1.5/2.0/3.0 are all fine. Any overclocking seems to be out of the question also, and I still experience some instablity at stock speeds now after it progressively got worse. I've been through all the possibilities (memory controller on the CPU hence buying a San Diego, mobo etc) but truly believe it to be the RAM now.
I've memtested the RAM for 8 hours on various different latency settings and it always passes. But it is never completely stable in Windows and will not successfully boot at CAS 2.5. Also, a Prime95 blend test will only complete tests at around 1/10th the speed it should do, even tho Large FFT tests are fine.
If I try the RAM in other motherboards (nF2, nF3 etc) I experience the same troubles. New RAM in my system is perfectly stable.
Has anyone else had such an experience whereby memtest cannot find any errors but Windows is not stable? Any other suggestions for testing before I RMA the memory? Clearly I want to be certain that the RAM is the trouble before I RMA it, but I really don't see what else it can be.
Any help is much appreciated as I am at wits end with this thing!
EDIT: just realised that my PSU isn't in the sig cos I didn't have room. It's an Seasonic S12 500w which I know some revisions can have problems with DFI nF4 mobo's, but this system worked perfectly for 6 months and the problem manifested itself over time and got progressively worse so I am not suspecting the PSU at this stage.

) and tried booting to windows with one stick at a time and with the CAS latency at 2.5. Sure enough, 1 stick worked fine and the other failed miserably.
