But aren't they replacing duff RAM with single sided stuff that doesn't clock well?
Yep, if you had double sided, it will be replaced with single sided. As for clocking, your right about that as well. I have a set of 2x1gb single sided that were sent back from rma, they just about run at the advertised speed. But take it from me, they do not go any higher. They have now been put in Mrs Kitfit's rig at stock. If you want to run the ram at stock speed and stock Vdimm then get some, as long as you're prepared to spend lots of intervals waiting for them to come back from rma. Because even at stock, they still die
