I'd like to request some advise regarding the RAM supported by the Unichip 367c mainboard:
I got this board some time ago with eight RAM modules equipped. POST said 8 MB ok.
Following the manual this board can support up to 128 MB, so this should be 8x 16 MB.
So I tried out four 4 MB modules which I already had lie around by substituting four of the modules that came with the board. POST still said 8 MB ok. Huh?
By chance I found out that the four modules I removed already were 4 MB modules, so the board originally came with 20 MB total.
Question is, what's wrong?
The 4 MB modules are all three chip modules (one of them for parity).
I have had some reading about refresh cycles and 8 (9) chip compared to 2 (3) chip modules but I don't get it yet. I suppose it is something with the number of address lines used but if the board really supports 128 MB it doesn't make a picture to me.
Does the board require some "special" modules?
If so what kind of respectively what parameter to look for?
