Hi Everyone, Ok, I had two RAM chips installed in my motherboard already: Motherboard is a Tyan S2266 512 MB DDR (Double Data Rate) (PNY) & 256 MB DDR (PNY) And I have Windows XP Professional Edition installed. Well, for those of you, who have XP Pro, you know, how the start-up screen has a little bar that moves back and fourth? Well, my system always moved the bar from left to right 3 times, and then Windows would come up. Then, I went out and bought MORE ram: 512 MB DDR (Centon) Now, on that windows start-up screen, the bar moves from left to right a total of 12 TIMES!!!!! It takes SOOOO much longer to start up now, with the new RAM installed. Does anyone know why this happened? Could it be, that it doesn't like (CENTON) brand RAM, or maybe that the more RAM you have, the longer it takes for Windows to come up? I have not noticed a decrease in speed during normal windows multi-tasking, but I have not noticed an increase in speed either. The only thing I noticed was the startup is much MUCH slower than it was, with only the two RAM chips. Is there a program that will let me test the new RAM to find out if it's working properly?
