Hi, I have a PCChips M560 motherboard which has an ALI Aladdin IV chipset

the other day i was working on it when I felt that it was running really slow, I thought it was beacuse of using an K6-2 at a lower FSB (83.3) but then i've put an PMMX and the same results.

there's also the posibility of that this motherboard is a different model and not an M560, the only thing I know is that it has:
2x SDRAM slots
4x SIMM72 slots
PCI and ISA
it has a dallas rtc that's working absolutely fine
it supports PS/2 mouse
and the chipset says "TX Pro" which according to some sources it should be an Aladdin IV+, but both XP and Aida64 says that's a standard Aladdin IV

So I remember that these motherboards may have problems with ram amount depending on the cache installed, so what's the maximum amount of ram that can be cached on these chipsets? or it depends on the L2 cache? mine has 1MB of cache I think

thanks.

Let me scrape my mind...

What Aladdin IV can cache depends on which external tag RAM is used. With an 8b tag RAM it can do the usual 64MB WB and 128MB WT. With an 11 bit tag it can do 512MB if you have 1MB of L2.

so...

I have to check which tag chip does it have and the right amount of L2 cache

from what i've seen, there is no way to change WB or WT in bios

it has 512KB of L2 cache and the tag chip is "UT61M256JC-12" it seems to be made by utron but i can't find anything more useful, also it has 28 pins.

That sounds like an 8b tag. Anything to do with Utron is pretty nebulous at best.

Probably easier just to test empirically. Fit the board with >128MB of RAM, boot DOS and run CACHECHK.EXE to see how much is cached.
