We'll replace it however, I can't say with what exact module as that is up to Customer Service. The modules you have are long discontinued so we'll have to replace them with something more current.
But as a Corsair customer buying stuff in 2009, I wouldn't expect the stuff I RMA in a years (or 10 years) time to be replaced with inferior product, simply because that's all you had at the time. In the EU you're offering a long warranty (10 years) but what you're really saying is that you can't stand behind it.
So anyone buying 'special' Corsair RAM today and paying a premium for it has no guarantee of getting anything as good when they RMA it? That's certainly not the impression I had of Corsair's warranty.
I had to send some stuff back to Crucial recently (2 x 1Gb PC3200 Ballistix) and they didn't have any so they sent me 2 x 2Gb PC4000 Ballistix instead. Now that makes me feel warm and fuzzy towards Crucial-Lexar, yes?
I sent an 8800GTX Water Cooled card back to BFG and they sent me a GTX280 H2OC back in it's place. Now I'm a positive BFG evangelist.
When I needed a new PCIe 8-pin cable for my HX620W PSU Corsair sent me a new cable set out, absolutely free of charge. Again, I recommend Corsair PSUs.
