Could I chuck these in my current build...?

[sehcure]

I have a Z68ap-d3 with 8GB of kingston hyperX the 2*4GB @ 1600mhz kit.

I just found two old sticks that i was wondering if I could chuck in, they're 1GB 1333mhz might even be DDR2 I'm not sure; they have no identifiable numbers or anything.

Would it even work? I'm just wondering before I throw them out...

if there ddr2 they wont,ddr3 have different cutouts so wont slot in the mb

yeh DDR2 won't fit and if its slower speeds I wouldn't mix and match anyway. Would probably have negative effects on performance anyway
