Re: Memory size, cacheable range and performance. Socket 5/7

I thought increasing the L2 cache on an MVP3 board was for the purpose of increasing how much RAM could be cached? I too don't fancy ALi SS7 boards because of the confusion around K6-2/3+ support. I use a 2 MB MVP3 board by Tyan in one of my builds. I know Epox and Tyan make 2 MB revisions that, …

Is the difference that big? As i think the Ali boards are better performers against the Mvp3 boards hands down, and I've tested a lot of them (mostly with 3dmark and Everest). But most Mvp3 boards I've seen only had 512kb cache and only one had 1MB (DFI board, didn't seem much faster as the 512kb …

there isn't much difference between m1541 and m1542, except that the m1541 pinouts are arranged for atx layout while m1542 pinouts for at layout. what matters is the revision as already mentioned. however, i've become uninterested in ali5 boards as its performance simply cannot match that of the …

Re: Latest Version of "Classic" BASIC?

You're right, it seems. Just checked in QB 4.5. May I ask why you require BASIC to sort the order of line numbers ? :confused: I'm curious, because what you're asking for is against what MS originally had intended (when moving to modern BASIC). Microsoft even released a tool, REMLINE.BAS, that …

i assume its gwbasic3.23 that works with line numbers. after that its replaced by qbasic and although it still supports line numbers, they have nothing to do with the order of the lines being executed. also i wonder whats the oldest dos version of microsoft basic that runs with pc compatibles( …

i had this idea for 15 years. however, only cards with support for both d3d and opengl count as true 3d cards, and that rule out most of them. also, cards with dual or more tmus count as a seperated group.

i think the easiest small socket7 boards to find are some cheap sis530 oem boards. they used to pretty plentiful in the dump yard here, but i wasn't interested in these slow boards without agp slot so i didn't bother identify factory and model.

didn't think the via694 would be so troubled, its quite usable and much more stable than the previous 693, except that it may require a lot of tweaking and still a bit slower than intel815 even when tuned to the max.

From what I recall looking at, the EDO speed with an ALi board is about the same as a non-ALi board (namely, UMC & SiS) with FPM. And the L2 results on the ALi were pretty sub-par. I have two of these ALi boards, but haven't published quantitative results vs. that of SiS & UMC. I remember being …

this old post looks very interesting, is there anyone else to verify on the ali1489 boards: 1. do they yield huge boost with edo than with fpm? 2. are their running without onboard cache as fast as with?

cache size difference has slight impact on 386 and 486 performance. the most significant importance of cache size is the range of cacheable ram: 128kb can only cache 32mb of ram, while 1mb cache can cache 256mb of ram. cacheable ram is halved if you set cache to write-back mode. for cache speed, …

its just a very common layout used by many brands which can't be identified. i have a similar board in orange with soldered cpu, which is unfortunately defective and wouldn't work with 128kb cache.

According to Wikipedia, the required CPU is a DX2-66 CPU.
