Did you install Tyrian when you had EDO RAM inside? No, I set it up when the two original FP sticks were in. I copied the game files from a USB stick (I have a couple of those ISA USB cards). Maybe that caused the corruption. Oh, and I didn't actually "install" the game, just copied the files over, …

@CoffeeOne: I already tried that; went from the original HDD to an adapter with SD card + fresh install. Another update: I now left the demo mode of Tyrian (instead of Tyrian 2000) running; has been stable for over an hour. Maybe it really is just an issue of corrupted software? Like I said: Doom, …

Update: Changing chips between banks didn't work. I then bought some 15ns 256k chips and inserted them today. Before that, I cleaned the sockets with some contact spray. Left the timings on auto. But still, the same error appears after running Tyrian 2000 in idle for a few minutes. Let's say I want …

OK, my logic is as follows: Since I set the jumpers to only work with one bank and I still got the same error, it makes sense that the faulty chip is in bank 0. So, I removed all chips from bank 0 (except for the tag chip) and moved the 4 chips from bank 1 to bank 0. Testing now. Even if I only get …

OK, thank you. The 16 MB RAM sticks I used to test were definitely EDO. The 2 that are now installed (and came with the PC) are FPM (just checked; they are marked as FPM). Is it OK if i just set the jumpers for less cache instead of removing the cache chips? I'm a bit afraid of breaking something …

Hi guys, I've been dealing with this unstable motherboard for a few days now and can't figure out what's wrong with it. The CPU is a 486 DX2 66 Mhz (5 V). It has a heatsink and an active fan (noisy at startup, but working) cooling it. Installed are 2 sticks of 72 pin RAM, 8 MB each. There are 256K …

Hi, I have the same card and the same problem. The on-board headphone amplifier is useless. By the way, it doesn't have any effect on the sound card's mode. You have to enable headphone mode in the driver/software from Terratec. Your best bet would be to disable/bypass the on-board headphone …

Looking at the 2004 version installer that cyclone3d found on retronn.de, there should be two folders: Drivers and Install. The driver provided by helpdrivers only contains the "Drivers" folder, but no "Install" folder and no installer. It therefore seems that these drivers are not meant to be …

Hi cyclone3d, thank you. That ISO contains drivers for one of the older Monster Sound cards, since files on it are dated between April 1997 and April 1998. It seems that the MX400 was released late 1999/early 2000.
