Adding old memory

[Count_Zero99uk]

Im thinking of putting my old 2 x Corsair CM2X1024-6400 - (so 2gb total)
into my new build.

Ive got

Intel Core i5 760 2.80GHz (Lynnfield) (Socket LGA1156) -
Gigabyte GA-P55-USB3 Intel P55 (Socket 1156) DDR3 Motherboard
Corsair XMS3 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMX4GX3M2A1600C9)


Is it worth it, or will there be a lot of noticeable slow down.

Im not sure of how the mechanics of memory speed work.

Thanks all.
Brian.

Ah, ok i might just get another couple of sticks of what ive got then. I thought that DDR2 would work in DDR 3 slots.

Thanks for the info.
