How can I tell what RAM will fit my computer?
I have a Pentium 4 computer, 2.40 Ghz, with two ddr memory modules. The former module is reported as DDR (PC2700) and the later is a DDR (PC2300), 256 MB each. The motherboard is ASUSTek, P4B533VM and supports up to 2 GB of RAM, 5 memory slots.
I have two other memory modules, 512 MB each, DDR, 400, CL3, PC3200U (as written on their labels).
The questions are:
- Will the "two other memory modules" work on my computer?
- Should I remove the old modules and use only the new ones or should I add the new modules?
