Did you follow these instructions from your manual? NOTICE: If you need to install memory modules in two connectors, install a memory module in the connector labeled "JDIM (Slot 1)" before you install a module in the connector labeled "JDIM2."
Dell Inspiron 600m; OS = Windows XP SP3
I'm using a Dell Inspiron 600m laptop that just started to have memory problems. About 1 year ago, I upgrade each of 2 original 256MB Dell ram cards to two 1GB ea Crucial ram cards that have worked well until now.
On boot-up, I get a "memory failed" message, and the available memory is reduced to 1 GB. To trouble-shoot this, I removed the card in DIMM B. Boot was then okay. I switched the card in DIMM A to DIMM B - still with okay results.
I set aside the first card and inserted the second card in DIMM A, then DIMM B, both with good results.
I then put both cards back into the ram slots, only in reverse order of their original position, and again got the memory failed message. I reversed them back to the original position and got the same message, so I remove the card in DIMM B and have again been working okay with only 1 GB ram.
I phoned Crucial, who promptly sent me two new 1 GB ram card which experienced the exact same symptoms as above, so apparently, the problem is not with the ram cards.
My computer will boot with only 1 ram card and continues to work okay with 1 GB ram in either slot. It just won't work with the 2 cards installed. Dell Tech Support would not help. I sent the two new cards back to Crucial, but my problem still exists.
Is my motherboard failing? Is Windows XP failing? Any ideas?
