OC with Twin2X1024-5400C4

[CoSMiCaL]

Hi guys! I recently bought a pair of these memory sticks.

But, or I'm being a noob, or I'm disappointed!

My last mems were 2*512 DDR2 667 Buffalo!
They were running at 429MHz 4-5-4-12, totally stable.

Now, with this ones, I can't even run 390MHz stable at 2.1V..
Is this a problem? or this Corsair model doesn't overclock at all?

I wish you guys could help me
Regards :)

Most likely, your previous memory was the D9 "Fatbody" ICs which OCs exceptionally well. Your current PC5400 is not going to clock as well. That is a lower speed entry level part.
