Noisy scsci harddisk and fan, but otherwise nice spec.

Nice one!

You're lucky you got it with dual processors and with a VRM fitted, as the VRM's for these machines can be rather hard to come by!

The CPUs look like Pentium II or Pentium III in SECC2 cartridges.

Ah, I see, dual Pentium III 550 MHz, so Katmais (Model 7 and 512 KiB Cache). Say, could you have a look on the used VRM to check who manufactured it and what P/N it has?

Do you have faced any crashes with Windows 2000 on this machine so far? Any special patches applied?

Congratulations, btw. :)

I have been looking for a reasonably priced MLA for a while, been thinking about trying to hacking something together with an LVDS board (ex. http://www.ebay.com/itm/161320408901 ). Maybe one day, when I have time to play around again.

The VRM in my machine is a: Celestica 073-20770-01 if this helps.

So a 073-20770-01 actually also works for the Visual Workstation 320 with dual CPUs installed. That's good to know. I remember that FlasBurn tried such a VRM in his VW 320 without luck - no stable SMP operation with Windows 2000 (not even during installation).

Do you have Windows 2000 installed on yours? And does it run stable for you?

I do run Windows 2000 on the system and it has dual PIII 1 GHz processors fitted. It does seem to run stable, but I don't use the machine that often, so I cant say that its completely stable.

It's stable enough to play games tough! :D

Here are some pics showing the system information:

You've got a really cool machine, now all you need to do is find a Pair of 1 GHz PIII's and your system will run like a machine! :D

Finding the matched pair of PIII Slot 1's @100mhz will also take some time. Good for my wallet also :)

What would that entail? Interesting looking board. With the scareness and prices for the MLA a small batch might be interesting for some here....

According to this table:

http://www.frontlinemedia.de/sgi320/vrm.html

That the 20770 works is an expected outcome :)

I remember this table, but the page is not very explicit in stating that the VRM types listed in the table are working or were tested in a VW 320. But maybe I misunderstand/stood it in the past, because the last sentence could as well be understood that way, i.e. that all VRMs conforming to VRM 8.3 or VRM 8.4 specifications are working for dual 1 GHz Pentium III in the VW 320. :?

Just had a closer look at the mainboard, it has the stickly label and is
revision 117....B! 29-mar-1999 say the other sticker.
