I have a P4P800 Deluxe board from Asus, and 2 sticks of Crucial 512 MB PC3200 Ram. I bought one stick when I first built the machine, and then recently went back and got a second stick from the same manufacturer, and same part number to do dual channel. My whole idea was to increase performance for HL2 and Doom 3.

So this morning, I reboot my machine and noticed on the post screen that it said the memory was in single channel mode.

I have them in the blue slots on the mobo, like it says to. I also updated this morning to the latest bios to see if that helped. Still have the issue.

So I opened my case up and looked at the dimms. I bought them both from crucial.com, and they are both 512 sticks of pc3200. Yet one has the black peices on both sides of the stick, and the other has them on only one side. So they are the same size but different?

I looked at crucial's ordering site and they list the memory part number with only the first set of numbers that are identical on both of my sticks. The number is CT6464Z40B, shown here: http://www.crucial.com/store/MParts...WSPN=CT6464Z40B. But they don't list a number on each dimm that comes after that which is different.

So are my sticks not identical and not available for dual channel? I feel like I got screwed, I went to the manufacturer who I had bought the first stick from, and got the one with the exact same part number but I got a stick that looks different.

Further, is there a system benchmark that I can run that will tell me if they are in dual channel mode but the post screen is just saying the wrong info?

OS: WinXP Pro Sp2
Processor: Intel P4C 2.4 Ghz
Motherboard: Asus P4P800 Deluxe
RAM: Crucial 512MB DDR PC3200
