triple channel ddr3

[minicle]

Hi Folks,

I need to pick brain cell or 2 on ram.

I have now, nicely long in the tooth i7 920 with 6gb of ddr3 triple channel ram. (spec in signature) I am increasingly finding I need more ram, but the world has moved and I can no longer just order another 6gb.

The ram I am using is
Corsair (TR3X6G1600C8D) 6GB (3x2GB) DDR3 1600MHz XMS3

The pc is overclocked and I ideally I really would like to match the ram. is this going to be possible? What are my options? Any thoughts?

Do I need to seek out something 2nd hand?

I like that OC have now found some, :]
It is just shame that it is somewhat overpriced. :{
