Dimension memory problem as follows: I had 2 X 512MB of RAM for 1.0 MB of memory. I bought 2 x 1024MB chips to upgrade per manual and installed one. The system recognized the new 1024MB chip and shows the ram as 1.5mg. I shut down and the second 512MG with the second new 1024MB and the computer would not start. Check trouble lights in back of computer per manual and it indicated a memory problem. Remove second 1024MB and reinstalled old 512MB - computer worked fine at 1.5MB again. (I am doing this upgrade to two computer so I have four new chips). I then removed the second old 512MB chip and put in a third new 1024MB chip. Same problem - no start and trouble lights show the same malfunction. Check BIOS and it is correct. Check F2 - setup at start... it is OK. Out of options. The new chips are - 1024MB 400Mhz DDR 1GB PC3200 Low DensityFSB - which are compatable for the Dimension 2400... Question.. The PC3200 are supposed to be backward (DDR) compatable with PC2700. Everything I read say that is so. My 512MB Chips are PC2700 (the dimension 2400 is a PC2700 system) and the new 1024's are PC3200. QQQ... Is the PC3200 backward compatable only when a PC2700 is present. In other words... I my computer read (when 2 x 1024 PC3200 installed) PC2300 and the chips are not backing to PC2700 therefore system will not start. That is the only reasoning I can figure... Would like someone else opinion and advise. Thanks - Mark
Yeah thats a normal issue with the dimension 2400 as the older bios only supports a max of 1gb of memory you will need to go to the dell website which ive linked below and get the bios update which will give you support up to 2gb-pc3200 ddr memory
