A few days ago I replaced my 64MB RAM with a 128MB module (IBM make). Now I have the following problem - on starting the machine, the memory check is OK (all of the 128MB). But the system always stops responding after a different period of work. I run the "mem" command from DOS-prompt: it shows only 64MB Total RAM available, but it also shows 128MB RAM free!!! Obviously the OS or the BIOS have some problems working with my new RAM. I checked the BIOS settings and I found the one called "OS for RAM>64MB". It has two options - "OS2" and "Non-OS2". I've tried but with to success. What should I do now?
More info about my system (it quite old) - TX-PRO chipset, Legend Hotbird Motherboard (perhaps 593), Cyrix MII processor 333MHz, Win95.
Can you give me some guidelines on the subject, please?
Thanks in advance,

The TXPro (ALi Aladdin IV) Chipset had trouble with some 128 MB SDRAM DIMMs. I don't know exactly why, but I assume that it has to do with manufacturing tolerances. I guess some DIMMs are just "better" than others. You might be able to get it working correctly by tuning the memory timing in your bios settings.
Set the OS for RAM>64 MB to "non-OS2", unless you are going to be running the IBM OS2 operating system for some reason.

I HAVE A SIMILIAR PROBLEM WITH MY COMPAQ PRESARIO 5166, WHICH CAME WITH 64MB RAM. I TRIED TO UPGRADE TO THE MAX RAM OF 384MB WITH 128MB STRIPS, PC100. IT WILL NOT BOOT WITH THE PC100 128 MB STRIPS. ANY SUGGESTIONS?
