There's quit a few speedsys scores listed here

386DX40 build

Here's mine from that thread

Could you also note which chipset the motherboard was used and what CPU/FPU are installed? I have edited the original post to reflect this. I'm trying to get an idea for which motherboards have the best L2 and memory throughput.

Yes, that was a fantastic thread. I'm hoping this thread will mainly contain just the Speedsys results and system specifications. I've enclosed their results, however I don't know which chipset they used. I'm particularly interested in what chipset is in Old Thrashbarg's computer.

I'm particularly interested in what chipset is in Old Thrashbarg's computer.

Mine is the old Sis 'Rabbit' chipset, with the 85C310/320/330 + 85C206. It's a Chaintech 325/333/340SCD motherboard.

If it matters, it has a Cyrix x87DLC/33 copro, and was set for a 10mhz ISA bus speed.

Also, I have 20ns cache, so I couldn't tighten the latency settings all the way. IIRC I was running a 3-2-2-2 setting, but the BIOS also has options for 3-1-1-1 or 2-1-1-1 that I could use if I had faster cache. I can't remember what the memory wait states were set to... maybe if I get some time I'll pull the machine out and check.

Wow, so you can get your cache and maybe RAM timings even better? That is amazing. That board would be the clear winner of the 386 race.

I just so happen to have a 325SD/325SCD/333SCD/340SCD board, but about 30 traces have been entirely eaten away by the acid battery. It is the worst case of battery acid death I've seen on a board. Even the through-hole copper cylinders have been eaten away, which is the worst news. I will try to fix it, but if there are any centre layer contact points at the through-hole, connection won't be made. I'll try to stuff in some conductive silver and a copper wire lead for the though holes.

If you ever bring that board out again, could you send me high resolution photos of about 3" square around the area where the rechargeable battery once was? I need top and bottom of the board. I'd need this to follow the traces for areas on my board where the trace outline is no longer visible (due to the ISP). I have the official printed manual and could make a PDF of it if there is interest in this.

Pulling the board isn't a problem, but my digicam quit working awhile ago and I haven't got round to replacing it yet. Not that it would've been able to take a detailed photo like that anyway.

However, I'll try to remember that request for when I can get ahold of a new camera.

I have no speedsys result screen from the Ali chipset 386 system though.

Elianda, that second system you listed is seriously nice. Is that one using the SiS Rabbit chipset as well? Could you take a photo of your motherboard for us?

Good call on the Tseng + TIGA combo. I have a similar setup in my EISA/VL 486, and it really gives the best of both worlds in DOS and Windows.

I too would like to see the motherboard; your memory read and move speeds seem unreal for a 386 motherboard. If you still have the system up and running, could you also let us know what results you get in cachechk?

I found the picture of Elianda's motherboard on his site, and it's almost identical to my Chaintech... the only difference I see is that his has a socketed processor whereas mine is soldered-on. I'm betting it's just a later revision... mine was made sometime in Q3/Q4 '91, whereas his was early '92.

Yes it is this one: http://mail.lipsia.de/~enigma/neu/pics/mainboard_386dx40.jpg

The system looks currently like this:

So not much chance to get a board photo.

I love that Soyo board. I used to have it as a kid, and I regret a lot selling it...

You should really take out that rechargeable battery. There is no telling when it will ruin your board. When you get around to changing it to an external battery, could you send me high resolution photos of about 3" square around the area where the rechargeable battery once was? I need top and bottom of the board to follow the traces to fix my board. Thanks!
