Thank you for replies guys.

Well, here it is.

It says 370 CPU CARD REV 3.2 and as you can see, there are bunch of jumpers and DIP switches to set different settings.

Okay now... does it work? Yes. It works!

I put a PIII 866 MHz SL4ZJ SOCKET 370 CPU on this "CPU CARD" and my motherboard recognized it after several failures.

In the end, I set DIP switch for 1.8V, jumpers to set OVERCLOCK and MANUAL.

Result is surprising.

With 600B, Voodoo 3 2000, 640*480 resolution, I was getting average of ~75 FPS in Unreal Tournament.

With 866, Voodoo 3 2000, 640*480 resolution, I am getting average of ~110 FPS in Unreal Tournament.

Also I can see it works much smoother in various D3D games as well as software mode games like Descent 1 in 640*480 and System Shock in 640*480.

I am happy with this. However. I've come this far. I think I can go a little further.

After seeing that the CPU can make differences with same graphics card, I want a faster CPU.

I don't think I can go Tualatin because its voltage limit is too low. So possible CPUs I can get are Coppermine 933MHz and 1 GHz. I am not sure which one to get but I think I will get one of them eventually. xD

It is a Shuttle Hot-C003 (also marketed as an AZZA brand).
You cannot run a Tualatin on it because it is not wired for that cpu type.

I think up to the Rev 2 they were also sold by StarTech, but not seen a StarTech version with switches.

A coppermine-compatible VRM (down to 1.3v) should be fine for Tualatin. However you need a modified CPU or modify the CPU/slotket yourself.

No.
Earlier post (july 24) by jedikwon indicated that his motherboard does not go lower than 1.8 volt and that voltage will ruin a Tualatin but the combination will likely not even post.
ooooooooo
I see my socket 370 coppermine CPUs have 1.75V written on them. The lowest voltage my motherboard can generate is 1.8V. If I can set the voltage at 1.8V with the adapter and try these 370 CPUs...... profit?!
ooooooooo
