Hello retro friends,

A few months ago I put together an SS7 system with an AMD K6-3 and V3 3000. Now I've got myself a K6-2 + in order to be able to play older, speed-sensitive, games more easily with the setmul option. An Epox ep-58mvp3c-m and Windows 98se are used.
But now I have a very strange problem. After changing the CPU, the Voodoo went on strike. I see the post screen and then the Windows start logo, but as soon as the desktop is to be displayed, the screen (Crt) goes into standby. I can still hear the windows start-up sound and with Alt + F4 I can get out of Windows again and the font reappears.->You can now turn off the computer.
What did I try:
Different monitor-same behavior
Other GPU (Matrox G200)-everything is fine
16 colors + 640x800 - is fine, as soon as I increase something, no picture is possible
put the AMD K6-3 back in - Voodoo shows a picture again
new instal of Windows98-no improvement, no picture in Windows with the Plus CPU
change Power Supply- no improvement
change drivers and GPU-Bios- no imprvment

So why does the Voodoo get the desktop displayed with the K6-3 and not with the K6-2 +?

Greeting
