Nice, well done!
This is why some gamers dropped the cash for 48MB, 64MB or more. They wanted the performance and it was worth it. I wonder how your testing would turn out with 64MB+ in that system... Do you have it to test? Suspect that result would be interesting.
I totally agree. It would be an interesting conclusion on that test!
Hmm, good idea but it'll have to wait I'm afraid. I just wrapped things up & disconnected all my testing gear. Overall this was a triumph, I'm making a note here - huge success! It literally is, considering I found (and restored) two rare AT "x86" based systems
Besides, adding more RAM into 5x86 system is a real PITA. EDO memory banks are located in upper-left corner, just below the PSU box. So in order to add (or remove) the RAM modules, I have to disconnect both the floppy & Primary IDE channel from the motherboard. Not to mention the two PSU leads, this thing is just crazy.
But do remind me about this, down the road, I'd love to do a proper comparison
What I'm guessing is that memory usage would proportionally increase up to a certain point, where the supply would overtake demand, and then you would see a noticeable "Free Memory" increase. In fact, this system might have originally came with 64MB of RAM, as it had all 4 memory banks populated with 72-pin modules.
What I'm guessing is that the former owner upgraded RAM mover time, especially later when EDO technology became cheaper. But with that being said, 64MB of RAM most definitely WOULD be overkill on a 5x86 system, since my Pentium II, 350MHz originally came with the same amount of RAM back in '98, '99 and it ran Win98 (along with 3D accelerated games using Voodoo2) just fine. Again, it could have been faster, but it was more than acceptable, I never even considered buying more RAM, not until I finally upgraded to WinXP in early 2000s
Update
I'm going through my old pics, and yeah - I was right. It came with 4 memory modules, but since I wasn't getting any feedback from the motherboard, I took out all the RAM, cleaned the banks with contact cleaning solution & replaced two of them back, just to see if it would post or not. And it did, system recognized 32MB of RAM. So with two additional modules, it most probably had 64 total.
