It's "E".

Thanks for the details. The other piece of info that EITHER of my 128-MB chips work on their own, or with the 64-MB (which is 8 chips on 1 side). Both give 128 MB on their own, and each gives 192 MB with the 64 MB DIMM. When I try to use both 128 MB together, I only get the 192 MB. Is that expected?

The chipset is ALi M1541 rev 4. (My original posting wrongly said M1545.) There are 3 rows of DIMM sockets on the M5ALC motherboard, PC100, with maximum memory possible 384 MB. No more than 128 MB in each socket. My problem is that even with two good, but different, 128 MB DIMMs, only 192 MB is reco...

The latest known 128KB Bios - please try this one.[/quote]

Thanks. I installed that, but still no change and still not seeing more than 192 MB.

Obviously I meant to write "MB" not "k". "No change, I still have only 192 MB recognized, even though two good 128 MB DIMMS are in the sockets. I guess that means it probably is an incompatibility problem between different types of PC100 memory - is a 4-chip-per-side DIMM configuration simply incomp...

Well, I upgraded the BIOS, using alc0331b.bin - it's a 128k BIOS, and alc0131b is a 256k file. No change, I still have only 192k recognized, even though two good 128 k DIMMS are in the sockets. I guess that means it probably is an incompatibility problem between different types of PC100 memory - is ...

Do you have a favorite flash program for a case like this?
awdflash? phlash? Which is least likely to creat problems?

No, I haven't upgraded the Bios. I did contact one of the Bios upgrade companies (esupport.com) and explained my problem to tech support there. They simply assured me the problem couldn't possibly be the Bios, and suggested it was because of the different memory types, so they couldn't be of any hel...

If I put one 128 MB in slot 1, and one 128 MB in slot 3, leaving slot 2 empty, only 128 MB total is recognised. However, the user manual shows slots filled up with the bigger RAM always in the lowest slot number, so maybe I shouldn't be surprised that if slot 2 is empty then slot 3 is ignored. (True...

The 128 MB memory sticks are different, although both PC-100. I have tried different permutations of different DIMMs in different sockets, but never get more than 192 MB. For example, socket 1=128 MB, socket 2=128 MB, socket 3=64 MB, I still only see 192 MB total. Swapping the two 128 MB sticks, no ...

This is with Award Modular bios V4.51pg Chipset ALi M1541 rev 4. It's an M5ALC board in a CTX computer. This claims (user manual) to work with up to 384 MB. I have a 128 MB in each of the first two DIMM slots, and only 192 MB, not 256, is being recognised - either by the POST at boot-up or by a memo...
