Hello all -
I seem to be having a problem with RAM on my Toshiba laptop. Its a 4270XDVD running Windows XP.
Win XP now detects only 192 Megs of RAM. That is 64 Megs built in, plus 128 Meg in one slot. But I have 2 128 Meg RAM modules filling in both slots (slots A and B), for a total of 320 Megs of RAM. It originally read 320 Megs, but it doesn't any longer. The RAM in both slots are exactly the same make and model, PC100s, non-parity, cl=2.
I have done the following to check out the possible causes of the problem.
1. Took out both modules, then inserted the first 128 meg module in slot A only. It read a total of 192 Megs.
2. Took out the first RAM module and replaced it with the second RAM module again in Slot A. It too read a total of 192 Megs (in both points 1 and 2, that's 64 internal plust the 128 module). So this suggests to me that the modules seem to be working.
3. Bought a third module (IBM brand) of 128 Megs and inserted it as well into slot A (replacing the second one). It worked fine as well, reading 192 Megs.
4. Tested inserting a 128 Meg module into slot B only (shouldn't work in this situation I believe). It read 64 Megs (the internal RAM only).
I edited the boot.ini file and added the /maxram=320 parameter
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /maxmem=320
and reinserted both modules into both slots.
This did not do anything either (still 192 with both slots filled in)
4. I went into the BIOS (booted up my laptop and pressed the ESC key) and it only detects 192 Megs with both modules in. There does not appear to be any Memory settings in the BIOS, and I believe I am running the latest BIOS for this laptop (2.70, as listed on the Toshiba laptop).
5. I downloaded a memory tester mentioned in one of the other forums here, but it only detects 192 Megs to begin with.
Is it possible that it is the RAM socket/slot for the module itself, or some voltage thing? I am getting quite frustrated by this, and hopefully someone can offer some points I may not have considered or some sort of diagnostic tool that I might be able to use.
thanks again
