If you have an x1900xt (not xtx) and have taken off the cooler, then post the type of memory your card uses, and also the manufacturer of the card. If the code printed on the memory chips ends with BJ11, then it's the 1.1ns memory. If its BJ12, then it's 1.2ns. If you have not taken off the cooler or do not have an x1900xt then don't vote for either mem. I'm curious if anyone has gotten a 1.2ns card, because I've mostly seen 1.1ns versions.
