What's wrong with the Kingmax sticks? Is it the voltage difference?
The Transcend sticks have the same latency as the XMS I think. PC2700 and PC3200 only really make a slight difference in synthetic benchmarks anyway, and lots of people seem to have had good luck with them in the mini-reviews. (Dell 600M, Powerbook 1.5, eMachines M6809, HP zd7140) One reviewer said they run a little hot, but that sholdn't be too much of a concern given my low operating temps. Hopefully I can find someone that has used them in the 3200 before I order, and I'll give Acer a call to see what they say. I'll have Acer put it in the slot under the keyboard since the service center is only 15 minutes from my house, that way I know my warranty will be intact and I'll be able to add another GB myself easily.
