One of my current builds feels very unstable and strangely sluggish in Win98SE, so I was wondering if you guys could help streamlining it a bit?

The current specs are:
PC-Chips M577 / Amptron PM 9000 motherboard (Baby AT)
AMD K6-III 450MHz
256 Mb RAM
Geforce 2 MX400 (the good one) AGP
Sound Blaster Audigy 2 LS
Audician32

The dual sound card setup was inspired by a thread here, but I’m not sure it is worth the hassle. The system is supposed to be a dual DOS/Win98 machine, that I would like to be fairly balanced.

For parts I have available I have the following:
CPU: K6-2+ 570MHz, Cyrix &x86 266Mhz, K6-2 333mhz
Video: 3Dfx Banshee PCI, Matrox G550 AGP, Matrox Millenium 220, Geforce 3 Ti200 AGP, TNT2 AGP, ET6000 PCI, and a couple of Voodoo2 12Mb in SLI.
Sound card: SB 32PnP, SB Live (LOL)

I a way I am kinda interested in going with the SB 32PnP for DOS, but it’s a mid ‘90 card, so I don’t know if that is a stupid, also would it be more fun to go with a different GPU? Would the Banshee suffice? Would a Matrox/V2 SLI build be fun or a headache..

What would you guys recommend?

Depends what are you trying to accomplish. Are you building a DOS machine?
Period-correct would probably be TNT2 or Banshee, and for sound AWE64 or Aureal Vortex.

if it's unstable, try single sided ram (if it isn't right now)

I had issues with this, even memtest was like: "good to go!" but it kept crashing, then I tried single sided ram and no more issues.

I just want to play DOS games and late 90’s games on it, without too much fuzz. I thought this system could be a base for trying out different video cards and stuff, but it just seems off. That is of course also kinda fun, to tinker with a temperamental system, but not all the time.

I have one 256MB stick in it, maybe that causes problems?

try a single sided 128 or two of them

Can you describe the details of the instability or sluggishness?

Windows 98, newly installed, was very unstable and could grind to a halt. Maybe it was because I had a voodoo5 in there for a short while, before going back to the Geforce (the V5 was semi-faulty). I’m on a new install of Windows 98 and haven’t touched too much.
In DOS I have experienced various issue with regards to memory, that I have never encountered before. That was somewhat mitigated by swapping in a new stick of RAM, so that may have been the issue. That the RAM was a large issue. I think it falls on the board maybe. I’m also having some issues with finding appropriate Geforce-drivers for the MX400.
I have the Audigy 2ZS running in DOS now, and in Win98 with the VxD-driver.
I’m still torn on if I should downgrade to a different video card, or stay with this, og try to throw in one or both of the V2’s. What do you guys think of the Banshee?

if you still have stability issues revert to failsafe settings and hardware and slowly start adding back loosen memory timings in bios, load defaults, try a pci video card that you know works, no sound card etc, get it stable then start building back

Good advice. Thanks 😀 I don’t know much about timings, but I’ll do my research.

Post the options

F4 or one of the f keys will list all options for a particular setting you can take a pic of that.

In general you can just load setup defaults, not always, but usually that’s a stable set of settings

3 on the one setting

Normal or 10ns on the other setting (try both)

Read pipeline “probably” isn’t at play, but try it enabled, and disabled. Enable of possible.

Cache timing usually has fast and fastest options you can drop that to fast for a while to debug the system and add it back as one of the steps later. (Change a setting, do a stability test for a hour, change a setting, do a stability test, change a setting, do a test, etc)
