Question about Dell Latitude CPX650 Notebook

2 Answers

Missing Ram I have a dell CPX 650. I just installed two new 256 Ram in the DIMM slots. It worked for a while. Now one of the DIMMs will not register. Both ram sticks work on DIMM A but not on B. How can I check to see if this is a hardward or software problem. Thanks.

That's what I thought might be the problem.

I bought a motherboard on E-Bay and will install it when it arrives and see if this does the job.

thanks

The DIMM B socket is probably going bad. I talked with a Dell Tech, she said a motherboard replacement would be necessary, but if you send me back the Service tag for the laptop, I can be a better help.

In the bios there is an option to install OS, make sure this is flaged as off, when you reboot you will have access to the full amount of onboard ram.

Dell Latitude D600 - RAM not recognized


One of the DIMMS might be incompatible or faulry.
Put one DIMM in at a time to determine which is not working.
If they both work separately then it appears they are incompatible together. Try to get the DIMMs from the same manufacturer, with the same specs.

Dell Latitude CPx H500GT fails when using 2x256 Mb memory in bay


If the laptop is in warranty, then dell will take care of it. Also, are the two ram sticks the same speed? mixing ram can be bad. also, goldmemory software is excellent for ram testing.
lastly, if there is a bios version that allows you to use both ram slots, use that bios. a newer bios is not always better.

RAM cuantity


The motherboard you mentioned supports DDR1 RAM.

For windows xp and general application 512 MB is enough.
But if you use memory intensive applications like image/video editing then you can opt for 1-2 GB RAM.

When i add a memory in damaged DIMM slot showing black screen?


Try moving the working DIMM to other slots, it should work in any slot, if it does, the other ram u have is incompatible or bad

Install a matched pair of DIMMs (equal in speed: DDR266, DDR333, or
DDR400; density: 64 MB, 128 MB, 256 MB, 512 MB, or 1 GB; and
technology: 128 Mb, 256 Mb, or 512 Mb) in DIMM 0 in both Channels A and
B. If additional memory is to be used, install another matched pair of DIMMs
in DIMM 1 in both Channels A and B.
