Hiya ppl, just a small Problem with a new 256 m/b memory chip in windows. I have only just changed over for the 2nd time a new P133 256m/b memory chip. I have installed this in Dimm 1 and in Dimm 2 slott I have a 128 m/b p 133 chip as well. Now in dos the computer has no problems whatsoever and operates fine.
Dos will find a total of 393 m/b of Memory. Now once Windows 98 is loaded I can only get a total of 112 M/b's. Yes I have tested the chips in both slots and also in the computer by themselves. Regardless of what I do the maximum I can get is 112 m/b from any configuration. This problems still persists even with the new chip I have just picked up. I am operatin a Celeron 700 on a Pcchips M754lmr Motherboard.
I have done a flash to Bios and upgraded to the latest version but still the problem persists. I am wondering if there is a bug or any other problem that somebody may know of that would be causing this
It would be greatly appreciated for any help that can be offered. that even means a free beer to you if your in Canberra

Rhy, I do not know if you have the manual for this mobo handy, but you can download it at http://18.104.22.168/M754LMR.html
On page 12, there is something about the memory configuration "If the installed CPU uses a 100 MHz system bus, you must use PC100 or PC133 memory. If the installed CPU uses a 66 MHz system bus, you must use PC66 memory."
The celeron 700 that you have is probably of 66MHz FSB, and the memory chip is of 133MHz. That might have caused a conflict in the system itself. I do not know how to explain the functioning in DOS, or how the 128MB chip worked, but I think that is a pretty good clue as to why it is not working.
