Hello,
I just installed a pair of new PC2-4300 1gb Samsung memory modules in my Dell GX280 Small mini tower. This system runs XP 32bit. Before I had the original 512mb PC2-3200 modules. The BIOS is the most recent A08.
I'm a bit confused that both the bios and cpu-z says that the module size is 512mb. But that the total memory size is 2048mb.
