Do you have a turbo switch connected? Some motherbords only works with full speed if the switch is connected or if you replace it with a jumper.

Thanks. Yes, I checked that already. It ran really slow with the turbo switch on.

That’s better. I can now get a score of 215 in Topbench.

You have a brake on your PCI and ISA bus.
They are currently clocked at 16 and 4 MHz.
In your Topbench you've lost VidMem performance.

Please do the following changes and send the Dosbench chart (not the Topbench one).

HOST / PCI CLOCK: 1:1
PCI Posted Memory Write: Enabled

So in conclusion.
I would say this 1995 computer was painfully slow only because of the 4x CDROM.
Installing Win95 from a. 2x or 4x CDROM drive is REALLY SLOW.

So I ended up swapping that out for a 52x drive.

But that is what users of a 1995 Win95 computer had to deal with.

Win95 installing wasn't considered "too slow" then, patience in OS installing was normalized by that point (and PIO was very tolerated at this part of the process). 4x was a fast speed for 1995.

Yeah, back in 1996/97 when I was working for a computer education school we use to install the computers over the network.
We could install the OS on 30 computers in less than 10 minutes.
Including programs and custom configurations and settings.

Curious as to what model LCD you're using for this particular build? How does it look with DOS games?

Reason I'm asking is because I about given up on trying to find in decent shape and on the look out
for LCD's that look decent as far as dos games go.

I have some CRT’s in my Garage but I use this small LCD in-house because it is easy to move around and light.
It has worked okay so far with 286/386/486/ and all VGA and SVGA computers.
Works with 600x400 and 800x600 and 1200 display settings.
Has worked well with all ISA , VLB, PCI ,AGP video cards I have tried.
It has a VGA and DVI port. But with adapter will work with HDMI too.

Its a Dell 19-inch like this one. But I use the non-wide screen.

Okay, I can see now that your memory wait states and L2 cache configuration is configured with best timings - for your write through Intel 486 DX4. (On a write back you could enable the Copy-Back option too)

Here is a Real Budget sound card that was released in 1996.
These were selling for $20 NEW.

It a 16 bit sound card for DOS, Win3x, Win95, IBM OS2, WinNT
A Very Versatile sound card with Good Clean Audio.

And It sounds really good.
Nice Clean audio.

Okay, How low budget can you go ?……

Here is what I found in my bags of components:
1) AMD 486dx4-100 CPU
2) 8mb Memory ( 2 x 4mb )
3) Conner 254mb Hard drive form 1993
4) Diamond tech ISA Sound card.

This is more of what a budget Win95 build in 1995/96 would have looked like.
That Conner hard-drive sounds Awesome. Like a type writer or IBM Keyboard. ( tap, tap, tap, tap, tap ).

I will benchmark it later.

My first PC was a 486dx2 50 mhz. Came with win 3.1... later bought the Win95 13x floppy upgrade (from Price Club IIRC).... don't complain about slow CDROMS 🤣.... eventually got a 4x Creative CD/SB16 kit.

P1 Build: Packard Bell - 233 MMX, Voodooo1, 64 MB, ALS100+
P2 Build: Dell Dimension R400 - 400 Mhz, GeForce2 32 MB, 128 MB
P3 Build: PIII @ 1 Ghz, 128 MB, GeForce2 GTS 64 MB

I even have an AMD 486dx2-66 to try.
As you can the Intel 486dx4-100 has almost twice the performance of the 486dx2-66 CPU.
And this performance difference is very noticeable during operation of the computer.

Did you bench your DX2-66 and DX4-100 in the same motherboard with same BIOS settings?

Yeah, I don’t know why the 486dx2-66 is running so slow. Let me double check the settings and jumpers.
