I can’t find any datasheets for it. This board isn’t as popular as the LS there’s barely any information alk. If you don’t want to remove the sticker, you can usually tell if it is UV EPROM by noticing the thickness of the chip and the sandwich look to it.

I’m also adding the manual in case someone stumbles m4187 this thread in the future and needs it. Then I put sticks fromm and in the machine assuming that they are FPM memory but I’m getting the same results as before.

I also have reason to suspect this is the clock generator for the SMT Terminator. I’d use a trimmer rather than a fixed resistor if mm1487 testing for an IBM 5x And stick with K cache. I suspect the memory performance differences may be related to the fact that you are using EDO memory, which not always means better performance in Besides needing to add a 3rd clock speed jumper S2 to the clock generator, I think the most difficult part of achieving 66MHz might be figuring out which jumpers are the PCI divider assuming it has one and CPU multiplier.


I have never witnessed first hand or second hand any improved benchmark results when using EDO on a PCI motherboard. I’d be happy run some time demos. If I remember correctly. I would not have thought the difference so large.

Users browsing this forum: One of my cyrix 5x chips needed 3. Return to General Old Hardware.

This really limits its usefullness with an Am5x or Cyrix 5x Sure enough the memory benchmarks dropped by a pretty noticeable amount, so it does seem like the ALi chipset will indeed leverage EDO RAM when available and unlike SIS, provides a tangible improvement in performance.

For reference, I’ve attached a manual and board layout if anyone wants to take a look. Faster than SiS as well. Parity should theoretically decrease performance since it’s more overhead for the chipset m1478 calculate the parity bits, so for the purpose of testing I was hoping to ensure parity isn’t being used on either board. Lai looking forward to your test results of EDO vs. One thing to note: I bought these two boards from a Ukrainian eBay seller and after some minor repairs both are in tip-top shape.

The LSe manual I have doesn’t explain what the individual CPU selection jumpers are, only where to put them for a particular processor.

Ideally, I would like to run a more thorough comparison and update this thread, viewtopic. Perhaps RAM write to 1 ws. That is the case with SiS boards anyway. Based on the 33MHz results there appears to be some real potential here!

I had K of cache installed, which can sometimes influence what fastest cache timings are stable. I’d like to be sure it’s an even comparison When I get some ,1487 tonight I’ll look closer and see if Alli can figure out which jumpers are for the multipliers. The more I learn, the more I realize how much I don’t know. If anyone in the states has a spare S3 Treo64 they’d like to send I’d gratefully accept, otherwise I can hunt one down on eBay.

I’d rather not tear the sticker off to find out I’m a stickler for detailsbut I suppose I could drop the chip into to one of my device programmers and see if they can identify the chip using the device ID bits. I did not bother to check mine with EDO.
