Memory speed on Abit NF9 (Nforce 570)

[tfboy]

Bit of a noob question on AM2 / nforce 570 so please bear with me...

I've had fun and games installing windows XP today on a new AM2-based system I've put together.

Random "missing files from CD" and BSOD.

Turns out that the memory I've put in is 667MHz stuff, and with the SPD timings the motherboard has been running it at 667.

I've throttled it down to 400MHz and it's stable.

Is this normal?


Edit: Just saw the review on hexus. Looks like I'm having trouble with 667 when the review talks about troubles at 800.

Mods, could you please edit the title to reflect correct mobo model number, i.e. KN9 SLI Thanks!

Sounds like either dodgy RAM or a BIOS setting/incompatability.

OK, makes sense.

I can run memtest and other burn-in memory testing apps, but if it does prove to be problematic, I can't find out whether it's a mobo or RAM problem - this is the only system I have with DDR2 ram so can't swap components to determine what's dodgy

[shaithis]

What RAM are you using? (Seems a lot of people are having issues with this board and most (all?) OCZ RAM)

Also, have you upgraded to latest bios?

[tfboy]

Not sure on Bios version, will need to check

RAM is Corsair Value Select PC5400 - 667MHz DDR2. clicky

Looks like that should be OK......I would upgrade to the latest BIOS and if that doesn't fix the issue, RMA the RAM.

try upping RAM voltage by 0.1V
