I am trying to upgrade the memory in a dell dimension B110. It had a 256mb pc3200 ddr 400mhz module installed and I added a 512mb pc3200 ddr 400mhz module. The bios shows both memory cards installed at single module showing 758mb total, but when you check installed memory using aida32 under winxp, it shows only 256mb using 86%. When you check in aida under the spd, it shows both memory cards installed and their correct amount.
I checked with the dell manual for this system before installing the 512mb to be sure it could use a seperate single module and it says it can. I even used a memory configurator when ordering the memory to be sure I was getting the correct memory for this model.
Why won't the OS recognize the correct amount of installed memory?
