Dell notebook - memory not showing up correctly
Trying to help out a friend who just got a hand-me-down Dell Latitude CPT
notebook. The person who gave it to him did a fresh install of XP on it before he passed it along. The laptop only had 64 MB or memory, so he bought two 256 MB dimms. When he put them in and booted up, bios reported only 320 MB of memory. According to the specs on this model, it should be able to handle 512 MB, so I'm not sure what the problem is. Any ideas? Thanks in advance for any troubleshooting tips you can pass along. |

Try updating the bios, you can get an update from Dells website under
downloads and drivers. You can also run a diagnostic check from their website, which will tell you if anything is wrong with it. |

See if both of them register okay. If they both seem to work, then try both again together. Hey there. Thanks for the reply. Well, I tried each stick individually and in both cases the bios said only recognized it as 64 MB of RAM. So it's just messed up all the way around. |

Well, I tried each stick individually and in both cases the bios said only recognized it as 64 MB of RAM. So it's just messed up all the way around. It is possible your laptop uses the 440BX chipset. That chipset has an issue with RAM past a certain density. For example, on a desktop motherboard, a DIMM with (16) 16Mx8 chips works right, and reports 256MB. A single sided DIMM of (8) 32Mx8 chips doesn't, and returns the wrong size when inserted in a computer. The single sided 256MB DIMM has earned itself the moniker "high density" DIMM, and is known to be a bad buy for a 440BX chipset. SODIMMs are a different size and have room for a different number of chips. But the chipset will still have the same addressing limits as it would in a desktop system, so the same density issues occur with a laptop using a 440BX too. If you go to the Crucial web site, you can search for the correct SODIMM for your laptop. Kingston also has a search engine. I have used four 256MB low density Crucial DIMMs on a 440BX system, for a total of 1GB, so I know it can work. This is an example of an SODIMM with room for 16 chips. 8 on each side. Perhaps this is the type that would work in the machine. I got this part number from the Kingston site. Check to make sure I selected the right version of Latitude. http://www.ramshopping.fr/images/pro...SP7500-256.jpg Paul |

Sounds like a memory speed problem, e.g. laptop requires PC100 memory and he installed PC133. Many older laptops are very fussy about memory speed. -- James |

Did you try them in both memory slots? Maybe one of the slots is bad. If it still reports 320 MB with both DIMMs installed look in the BIOS for memory configuration. It should show how much memory it sees in each slot. nikko wrote: wrote in message oups.com... nikko wrote: Trying to help out a friend who just got a hand-me-down Dell Latitude CPT notebook.

Does the laptop have integrated video that is using some of the ram as Vram?

One of 2 things:
If there is 64 MB on board, then one of the DIMMS is not installed correctly or is not working with that memory (try swapping slots) - or (more likely) - one of the DIMMS currently installed is 64 MB! Good luck. -- Thanks, TheBurgerMan at gmail.com -- "nikko" wrote in message ... Trying to help out a friend who just got a hand-me-down Dell Latitude CPT notebook.
