They are all 1MB! 😉

It just that its ROM and not RAM, when it comes to RAM you are 100% correct, 0KB, 512KB and 4MB are the only existing sizes with the 0KB versions beeing labeled as SB32 although they are AWE64 based.

Refer this topic: Re: "Standard" 1 MB RAM AWE64
It basically addressed the same question you raised. However, there never was an AWE64 that had 1 MB of RAM on board (the standard General MIDI sample set was stored in a 1 MB ROM, which I think is where the confusion might have come in).
You either had a "value" card with the standard 512 KB RAM on board or the AWE64 Gold that came with 4 MB RAM on board (apart from some other "extra" features).

However, if you had the RAM expansion modules (there were some cheaper after market options available), you could basically upgrade your RAM to 28 MB.
Refer this topic for some info on the Simmcon adaptor: Simmconn AWE64 Adapter.
Quite an interesting story on the 2nd page of the guy who manufactured this particular adaptor.

PS: The SB32 was actually a derivative of the AWE32 and not the AWE64, since some SB32 models still had the simm expansion slots but, no Waveblaster connector or the CSP (ASP) chip. It also utilised the Vibra chipset that didn't have any treble or bass options in the mixer but, some users have reported "cleaner" sound output on these models.

0KB version is SB32 CT3670. And it's probably the only AWE64-based card to have SIMM slots for expansion, which, in my eyes, makes it superior to AWE64. I mean, you sacrifice WT header, but it's buggy anyway.

Btw, CT3670 is very common in Russia, I got three of them, but for some reason I never made pictures.

Well, this is just nonsense. There were different models of SB32, based on AWE32, AWE64 and Vibra16.

I also think I have at least two CT3670, they are nice cards indeed. I thought an AWE64 based SB32 version without the SIMM slots existed but I probably got it confused with some AWE32 or Vibra based version or perhaps some strange cut down OEM card.

I never considered the SB32 models to be value orientated versions of the AWE64. They were originally introduced in June 1995, whereas the AWE64 was only released in November 1996.
However, looking at some of the model numbers, that might be true. Were there ever SB32 models with a DSP chip that had version 4.16?
That should confirm whether any of these were manufactured/released around the same time as the AWE64.

PS: According to Creative's own website, the CT3670 is an AWE32 and not a SB32.

It's an SB 32 PnP 😀
