Spec me some RAM - mix and match?

Another spec me some RAM thread!

I have the following motherboard:

Epox 9NPA+ running a AMD Opteron 146
2 x 512 DDR (2700/3300 - I think)

When I first upgraded my system to the above, I attempted to overclock the CPU, but didn't get anywhere due to the mismatched memory (apparently).

Now I think it's time to get some more RAM, so I need some advice from some experts on what exactly I need. Does the new DDR2 RAM need to be paired up like the SIMM/DIMM back in the old days? AS I notice everthing seems to be sold in pairs of 1gig.

Thanks for the advice in advance!

Are you aware that DDR2 won't work in a 939 board?

Nope... I didn't think my Mobo was that old! :confused:

Guess i'll have to stick to regular DDRs!

AMD had to move to socket AM2 to provide support for DDR2.

Have you tried running the memory on a divider whilst overclocking?

Running the memory slower than the fsb is fine with AMD systems.

Too be honest, i'm a complete n00b when it comes to overclocking. But when I first played around with it back in 2005, I remember the PC kept hanging up after the tweaks - after looking around in forums, it seems it's a symptom when i'm using crap generic, unmatched RAM

Not even sure what a Divider is! Think i'll just get some DDR chips, or wait til my next upgrade and change mobo and RAM completely...
