2003 Dell Inspiron 5100 Laptop, Pentium 4, 2.4GHz. Windows XP operating system.
I've been reading about the possibility of upgrading the RAM in my laptop, the widely accepted maxium memory upgrade is 2gb (1gb x 2), provinding the bios be upgraded to A32 and keeping the RAM speed PC2100 (DDR 266MHz) and no higher. Up to now I've been runing the original 256mb card in the primary slot (DIMM A), and aftermarket 512mb in the secondary slot (DIMM B ).
Recently I purchased two 1gb PC2100 cards on ebay, but I can only ever have one of the new cards installed without having problems. Essentially, the computer does not like to see the 1gb card in DIMM A, however both new 1gb cards work fine in DIMM B. The computer only runs at full memory if I keep the old 256mb or 512mb in DIMM A. If I try to run the computer with 1gb installed in DIMM A, I get an error which reads approximately: "Memory read/write failure at "xxxxxxxxx". Read "xxxxxxx", Expecting "xxxxx". Decreasing available memory." The "x" locations are numbers, having to do with the DIMM locations and memory addresses, probably not necessary for the trouble shooting of this problem. When 1gb is installed in DIMM A (plus any other configuration in DIMM B ), the memory is decreased and windows runs at 512mb. So far the maximum working configuration I have found is 1.5gb (512mb in slot A, 1gb in slot B ).
Does anyone have any advice on how to get the full 2gb to work?
Thanks in advance!
