I've never heard of this type of problem. Memory is guaranteed for life typically by vendors. If you try another round, check the RAM voltage. It normally autosets, so unless you deliberately raise it, this seems unlike to kill your RAM. Normally RAM wouldn't be harmed anyway; normally the machine will just not boot or it'll blue screen if the voltage is too high. Try to check for any electric shorts where the motherboard under surfaces might touch a metal surface.
