I installed 2 pc66 32meg sdram modules to a 586 mainboard running with a cyrix 233mhz processor. the old ram was edo. when booting up, it recognizes the ram and the system makes it to the windows 95 startup screen but freezes and wont resume.

Here's what to do:

Reinstall the sdram (ensuring it is correctly seated). Then reboot. If the problem is still there, remove the sdram and install the edo ram. reboot again, if the problem is still there, reinstall Windows. If the problem is gone, check with the mainboard's maker to see if it can accept sdram, or if jumpers have to be changed, BIOS updated, etc.

Good luck,
Dusty

In most cases SDRAM should not be used with EDO RAM. The reason being the timing is different. You should run only one kind of RAM at one time.

Check the bios to see if changing the ram reverted you to bios defaults for memory settings. Cyrix processors have to be set for linear burst mode, not interleaved. This setting should be in the chipset settings.
