dual 256MB pc3200 modules in i865p chipset Dell laptop. Got a pair of 512 micron modules of same spec to upgrade and will not boot with either or both.
With one of the old modules in one slot and a new one in the other it will get to the bios memory check but fail with memory errors. The errors shown indicate one address getting the expected result of another address that in turn reports the correct result for the previous location. Bios terminates at this point with an option to go to bios.
Seems like a bank addressing problem with these 2 different unmatched modules and the error is in the new 512 part. Just thinking out loud here, such a problem should not occur, just dual bank operation suspended.
Reversing these modules does not yield a boot at all so it seems the module first addressed being the old working module allows boot entry. These are compatible modules as far as specs go as far as I can see. Am I missing something?? Same spec, double size, half of maximum allowed.
Can both replacements be bad or are there compatibility issues in these identically specd. parts??
