I have a Dell XPS T800r with Windows 98SE and 640MB RAM (two 256MB modules and one 128MB). After replacing the 128MB module with a 256MB one, I encountered a reboot loop. The RAM was properly seated, and according to my research, the motherboard should support that configuration.

The motherboard matches the required frequency. If you revert to a previous setting, it will restore the original configuration.

You should clear all existing memory modules, replace them with the new ones, and check functionality. If successful, proceed further. If not, the issue may be with the memory type or motherboard chipset (possibly due to frequency limits). Use memtest on a CD, floppy, or USB drive (if bootable) to verify the RAM. Keep in mind that Windows 98 SE supports up to 1 GB, but performance drops significantly after 512 MB. Consider updating your INI file to resolve memory-related bugs if you exceed that limit. See https://www.techrepublic.com/forums/disc...dows-98-se for more details.
