Compaq Presario 4410US Memory Upgrade Problem
Hi,
In some instances your PC may not be properly recognizing one or more
memory modules. Because you've recently installed new memory, check to be
sure it's properly seated in its socket and the module is compatible
with your system.
If the module is properly secured and
appears to be compatible with your system, remove the RAM and try cleaning the pins using
rubbing alcohol and a cotton swab. Clean each socket on the
motherboard, as well with a soft, clean, dry paintbrush and then blow the remaining dust out.
If problems persist, try changing the
order of your memory modules. DIMM sockets on the motherboard are
labeled (DIMM0, DIMM1, etc). You should always start installing memory
in the lowest numbered socket available. In many cases, the BIOS will
probe the memory module in DIMM0 and address all memory according to
the specifications of the module in DIMM0. If you've installed faster
memory in DIMM0, the system may not be able to communicate with slower
modules in other slots. Placing a slower module in DIMM0 may fix your
problems; however, the faster modules will then, of course, run at a
slower speed).
Hope this helps.
