Hi there!
I've decided to rebuild my first pc, an amd 386dx40. I'd bought the same midi at enclosure, after I've found a motherboard very similar to my ex 386's motherboard. It is a noname motherboard, with IIT fpu, 8mb ram, 128k cache. After I've installed the remaining parts and etc., it seemed to be, that the performance is not as "high" as i remember.
For example. Cubic Player 2.0 lags with almost every kind of module, even with Gravis (but v1.666 fine). Doom was hardly playable, which far more interesting. But the most weird, that Mortal Kombat was unplayable...and i remember, that i even played mk2 on my 386dx40 absolutely fine after i've got 8mb ram.
I've checked the cpu with landmark v2.0. All i remember, landmark that time used to display ~80mhz for the cpu (of course, compared to a 12mhz 286). This time it showed around ~52mhz. Pretty big performance leak, huh? Upgrading to 256kb cache doesn't changed anything. Although, some faster cache timing rule in the bios managed to speed up the result of landmark to ~60mhz. Still below the wanted ~80mhz.
All i remember is this landmark result, as exact performance value. But compared to my friend 486sx25, my 386 was faster in lot of games. The 486sx25 got ~81mhz result from landmark 2.0, according to a not too old test from a friend of mine, who tested around half year ago a lot of 486 cpus. This means to me, that i'm not the one, who had false memories, and something is not right.
What ideas do you have folks?
