Hey Everyone, I just installed 2 x 512 MB ram today to the factory 2 x 256 MB. Everything seems to run fine. The system profile reads that I have 1.5 GB of ram. Although, I see under the speed list that all are running at PC3200U-30330 except the DIMM2 reads PC3200U-25330. Is there a reason for this? The memory I bought was Centon PC3200 DDR400 and are both the same. Thanks for any info!
