Hello there fellow retro-gurus
Well, I'm not really a guru since I need help but anyway...... 😀

My friend gave me his MMX-233 in this config:

* Mainboard: Chaintech 5VLM M101 (if anyone has a manual for this since I only found 3 dead links so far) with 16MB RAM *EDIT* Just found some info on the board
* GPU: Some SiS card (didn't look at it further ATM)
* Soundcard: Avance Logic AV 310
* HD of course running W95

Now so far I only added a Voodoo2 but I want to upgrade the RAM to 32MB and maybe add another sound card too.
I noticed 2 different types of RAM slots. The ones that are filled are 72 pins double sided RAM. Am I correct? But what is the other one?

What is my best upgrade path?

Change the 2x8 into 2x16 72-pin since I'm guessing that mixing different types is not possible of recommended?
The mainboard has PCI and ISA slots and the sound cards that I have here are AWE32 PNP CT3980, AWE64 CT4380 , AWE64 Gold! CT4390 + CT1950, SB 16 Wave Effects CT4170, Audician 32 plus and a Sound Galaxy Orion16.
Or should I stick with the AV 310?

I've read a lot of MMX build threads but there are a lot of trees in the forest!

Thanks for looking!

You've got lots of options for audio. I'd experiment a bit to see what you like.

As for the memory, a bigger picture would help. But they could be 168-pin DIMMs.

Think you are correct. That was common for many boards to have both 72-pin FP/EDO ram and 168pin SD ram. You could even run both types simultaneously, but i was always sceptical doing that and just used one types. Think i read somewhere that SD ram in some cases wasnt any faster than good EDO sticks. True?

Yes 168-pin DIMM slots along with SIMM, as common with many 430VX (and 430TX) boards.

As for finding manuals... unfortunately Chaintech has become one of the more obscure names. Scarce documentations online. 🙁

Oh, but you're lucky! 😀

As for RAM upgrade, it's probably best to go with SDRAM provided you can find ones that are compatible with this board and can use them without the SIMM. Or go SIMM only. Just to avoid potential problems (esp. voltage mismatch).

Also with SDRAM on this board, best bet would be to use 32MB PC-66 sticks. Related:

I found the first link archsan but the other ones are an excellent addition.
As for the sound card, I'm gonna start out with my AWE64 CT4380 and see what it gives.
Done some searching on Evilbay and would these be good:

I wouldn't bother with an AWE64 if this is going to be a DOS build but for 9x it is not a bad choice, you can upgrade the ram to 64mb for almost nothing. As for the card you got a lot of options and the vast majority of them are cheap.

Seems like chaintech didn't store full manuals on their site in those days, but just in case these are useful:

For sound I have a Creative CT2900 ISA Card, based on Vibra 16S chipset in my P200MMX build, worth a look as they're very affordable, sounds great and I paid £12.50 for mine (€15). About one third the price of AWE32s I was looking at !

If you're going to use SIMM, then why not EDO DRAM instead of FPM? Usually from the era would be 60ns sticks.

For system memory, I'd definitely go for SDRAM, and upgrade it to 64MB (the cacheable limit). It's faster than EDO most times, can be used in single module configurations, and really easy to find (flea markets, old pc's, etc.)! In my opinion, it's an advantage to have DIMM slots on Pentium motherboards 😀

^Yeah, I'd go with SDRAM first myself, simply because I have some PC-66 and PC-100 sticks ready for testing. 😀 But primarily also because of the flexibility of not having to pair sticks (so I can use single 32MB module if I needed to).

That said, on a VX board it probably wouldn't be that much faster over EDO DRAM:

From my experience, later Socket 7 boards usually play nice with nearly any PC-100/PC-133 SDRAM memory stick. They are cheap, easy to find, and usually cause less issues than SIMMs. Also, I might be wrong, but almost all 32MB SDRAM sticks are PC-100 or PC-133, so you can't really go wrong there.

AWE64 is a nice place to start: drivers are easy to find, installation procedure is well documented, and you get SB16+AdLib(emulated)+General MIDI in one package. It has some issues with General MIDI under pure DOS, but a lot of mid-90s DOS games support AWE32/AWE64 natively and you can run most other titles under Windows 9x.

SDRAM support on socket 7 is strange. Apart from the memory caching limit of the various chipsets (i.e. you have to use small sticks in order to gain performance), some early boards used to support only single-sided sticks. Also keep in mind to check the voltage jumper as SDRAM is 3.3V, not 5V. From personal experience they don't get damaged immediately, they just run rather hot, not sure if you would want that. Don't actually know how long they tend to last when used that way 🤣 The only advantage of it vs EDO is that it doesn't need to be paired with a matching stick I guess.

Things are getting complicated now 😀
I really lost touch with old HW sorry
So it seems according to a link posted here, the VX set takes only max 32MB sticks.
Are these the ones I need then:

@psychz: I don't see any jumpers for ram voltage or am I getting blind here....

At such cheap prices it wouldn't hurt to try both (that is, one type at a time).

However, due to questions about voltage (whether the board regulates the DIMM separately and automatically or if there's a jumper unknown to you), for simplicity's sake at this point I'm going back to my EDO DRAM recommendation. If they work then having SDRAM wouldn't be much of a difference anyway on this system.

Yeah, it's more convenient due to the ease to find SDRAM modules. Additionally, if you're using PC100/133 modules (more usual than PC66), you can often tweak memory timings on the Bios to gain a bit more of performance. When using SDRAM you should configure jumpers to bring 3.3V to the modules!

I remember that our original Pentium 166MMX - 430TX based (first pc) was upgraded in 2001 to 256MB SDRAM (one module) and a 20GB HDD. It worked perfect! When we got rid of it a year later, the memory module was moved to our new Pentium 4 machine. 😀

Some years later, I was asked to upgrade a similar machine (only used for office purposes). I tried another 256MB module that I had lying around, and its VX chipset if I remember it ok, recognized the amount of 128MB (the max for this chipset).

But back then I had no idea about cacheable limits! 🤣, my current Pentium setup uses a more modern (SS7) platform. I'm curious to buy a cheap Intel based motherboard to test and benchmark 🤣 🤣.

PD: It's VERY important to use modules that have memory chips on both sides, I experienced problems with single side modules on these kind of machines! Also, when those PCs were upgraded, I remember to remove old SIMM modules before installing the new DIMMs.

As others have pointed out, it's for SDRAM (430HX ones (if they had any) were supposed to only support EDO in its DIMM slots though).

Iirc 430VX would only work with those earliest density 16MB or 32MB SDRAM sticks with 8 chips/1 side or 16 chips/2 sides (usually these SDRAM modules came in these configurations).

Another thing I noticed is that these earliest SDRAMs had chips on them with far fewer pins for each individual memory chip (the chips were a bit shorter) and were mostly PC-66.

430TX was supposed to be easier with the higher density SDRAM modules.

But for a VX build, I'd go with 2 of those early PC-66 32MB modules as I should have tons of those around anyway, but I'd go SIMM if the VX board has only a single SDRAM slot, which would limit total amount of memory to 32MB while 4 SIMM slots I could go up to the maximum cacheable 64MB.

I'm a but rusty though, just passing by again 😀

Mixing SIMM and DIMM could be problematic (maybe not at first, but perhaps down the road) and many manuals at the time advised against doing so.

I'll look to order 2x32MB EDO 60ns then.
I hope to install the AWE64 this weekend en next the RAM so I can finish this small upgrade.
Not planning on tinkering with speeds and voltages 😀

Thanks for the help guys! Much appreciated.

Actually most of 32MB SDRAM sticks were rated @66MHz. I'll refrain from stating that 133MHz 32MB modules don't even exist in case I'm totally wrong with this, but I was working in the field at that time and they were certainly not common.
