Can you post a photograph of your 486DX4 please?

More 1995 photo stuff :

Ah, a write back i486 DX4

Some more photos:

You have shown here several sound cards for this built. Which one(s) you actually want to use?

About your Edison 16 Gold: Have you already tested it - all the functions?
I had an old post here, several years ago :
KWX-SC1616

It's actually the same card.

There are 4 CDROM interfaces :
Sony, Mitsumi, Panasonic and IDE.

But for CD-Audio-In, there i can see ports for Mitsumi, Panasonic and Sony only.
Then you can see 3 further 4-Pin headers behind the connection ports 'Line-In, Micro and Speakers'

I think the Sony CD-in connection is working to IDE drive's also, or not ?

I'm getting a bit confused about this build. A typical 486dx4/100 from the middle/end of 1995 would have about 4-8mb ram, the cheapest grapics card you could find and a 540-850mb harddrive.

You have lots of ram, a really small harddrive and a very expensive grapics card (s3 968 based) that someone buying a high end pentium would chose.

I had to check some prices from 1995 after reading this post. This is from a Swedish supplier in july 1995.

Complete 486 system with 14" svga.
13000 SEK ( about 1500 USD without VAT)

540mb harddrive
2000 SEK or 225 USD without VAT

4mb 72pin fpm
1600SEK or 180 USD without VAT

Yes, I tried to use Plug-N-Play sound cards from or before 1995 or that would work good with Win95.
This motherboard bios actually does not support Plug-N-play but Win95 handles it fine anyways.

Sound cards I have tried that work well with Win95b default drivers are:
1) Sound Blaster 16
2) Media Vision PAS16
3) Edison Gold 16
4) Turtle beach Monte Carlo ( Also known as “K2Y-Pro16” ).

The Edison Gold 16 actually uses the ESS688 audio chip and Yamaha OPL3
Win95 install CD installed the default drivers and it is work fine.
I did not check all the connections or functions of the card.

Yes, I wanted to replicate a 486dx4-100 budget build of 1995/96.
But I wanted to use Plug-N-Play cards.

The motherboard I am using actually does not support Plug-N-Play but Win95 discovers all plug—n-play cards anyways.
Win95 discovered and installed drivers for the video card S3-trio64, NIC 3com 3c509b, and Edison gold 16.

Yes, components were expensive still in 1995/96
So yes, 8mb and 16mb of ram was more common.
I remember working for a computer internet portal company back in 1997 and we had an HP PC with 32mb of ram
And I thought that was allot of RAM back then.
I just used 32mb of RAM because I had it on hand and wanted to eliminate any bottle necks
In the OS performance.
But, I also swapped out the 4x CDROM with a 32x CDROM because that 4x CDROM drive was painfully slow.
I had a 2x Sony CDROM drive back in 1993 and that thing was really slow when I upgraded to Win95 so I remember
I ended up swapping that out for a 4x Mitsumi.

Other than that it performs okay for a 486 CPU.
The only real bottle neck was the 4x CDROM drive.

I selected components dated 1995. Except for the CDROM drive.
I might change the memory size to 8mb or 16mb.

I ran some benchmark programs and this build is running SLOW.
It should be posting a topbench score of about 220
But it is only posting 165 ?

Other than that everything is working fine.

Any ideas ?
See my bios settings do they look okay ?

Your BIOS settings are very poor.
Try to change and test up to each of the settings:
L1 Cache Update Scheme: Wr-Back.
L2 Cache Update Scheme Wr-Back.
-> Test Floppy Read & Sound Card digital sounds.
L2 Cache Wait States: Should be good for 2-1-1-1, if not 3-1-1-1
DRAM Read/Write Wait States: Both may be set to 0
Early Cache Write Mode: Enabled (? I am not sure)
Slow Refresh: May be set to 1

System / Video BIOS Cacheable: Yes
Gate A20 Option: Fast

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 CRT's in decent shape and on the look out
for LCD's that look decent as far as dos games go.

Okay, I was able to get this to run faster with a topbench score of 198.
Ideally, I would like to get up to 220 at least.
Maybe I can tweak the bios a little more.

Sorry, I focus more on the SpeedSys charts.
It still does not show a good performance though.
Which settings do you use now?

Here are the bios settings I am using.

Enable Slow Refresh.

Please disable Auto-Config.
Ah you still use the 3-2-2-2 L2 timing and the 2 / 2 DRAM waitstates 🙁
This still expalins the snail performance.

I have able to score 199 on topbench but thats it.
Even if change those settings the benchmark score remains the same.
I am using 32mb of FPM -60ns RAM.
