u cant use dual channel memory with a xp. For AMD u can only use on socket 939 systems
Dude, what are you thinking....dual channel runs on XP systems
I don't know where you got this idea that it's limited to AMD64 system as dual channel has been around forever.....the memory doesn't have ANYTHING to do with dual channel besides the fact they have to be the same sticks....it's the mobo and the CPU that actually control whether or not it runs in DC.
Regarding Cas latency of 1.5......Cas latency doesn't even effect bandwidth or performance for the most part dude....you'd need some BH-5 memory with a good amount of voltage to even to get it to run with that tight of timings and chances are if you don't know what I'm even talking about when I say BH-5, then don't expect to just go out and buy some corsair XMS and run it at those speeds.
