The Gold! model AWE64 cards are CT4390 and CT4540.

Value models are CT4380, CT4500, CT4520 and CT4550

My guess is that the RAM is not compatible.

wouldn't shock me if the PAL was dead. Those PALCE chips were pieces of shit

there's mention of jumpers in the manual, yet no mention of jumpers in OP's post.

No jumpers on the card that I can see, only one is to enable/disable the ASP chip (there is none).

ASP? that's the soundcard itself right ?
I was referring to the simmconn card since you linked to the manual.

Sorry, yes the SIMMCONN is set for 32MB.

I reached out to the good folks at Serda Shop and they sent me this info.

It seems the 'value' is only listing 16MB modules as successful and it's a guess on the 'standard' version of the card.

the green V is a 'Value' firmware,
CT4520 is a value version, so this should work
CT4380 is a 'standard' version, i am not 100% sure, i think it would work as well with value firmware
for the memory, i cannot find this type in the simmconn thread, so maybe it is not compatible
From my site (https://www.serdashop.com/SIMMCONN), these are modules i know that worked for users :
Known working 32mbyte memory modules :
- HYUNDAI HY5117400C J-60
- LGS GM71c17400AJ6
- SIEMENS HYB5117405BJ-60
- OKI M5117405A-60SJ
- MIT 417409DJ EDO-60
- M.tec TBE1604A2A60

I have an AWE64 Value (don't remember the CT number) and it works perfectly with a 32MB SIMM

Are you able to provide a link to the chips you used? I can't find any 32MB modules with the supported chips. I did order a 16MB one a few moments ago but I can always use a new keychain.

I honestly have no idea. I just pulled a random 32MB SIMM out of my stack and it worked.

If you've already purchased a 16MB stick I would recommend you test that first to make sure the SIMMCONN works at all before buying anything else

was easy enough to find this one.

Hey all, I wanted to provide an update.

Hi, I wanted to let you know because you were so kind to respond that I’ve tested with some other EDO memory modules I found around.
It recognized a 8MB of RAM chip that I installed in the CT4380 with the value firmware.
Without it it only recognized 512K

Oddly enough setting what I understood to be a 16MB chip to 16MB on the card only recognized 2MB
Dropping it to 8MB picked up 8MB in the diagnose utility but the memory chips are not listed as supported it will be a few more weeks for that as it takes a bit for stuff to get here from China.

While the ram-co-shop.de was the modules I'm looking for, it does me no go as they don't ship to Canada. Thanks for the link weedeewee.

The CT4520 I think is defective.

Thank you for the prompt reply, it’s greatly appreciated.

If all tests pass with the DIAGNOSE.EXE utility then your card is *extremely unlikely* to be defective.

So I'm not having much luck here getting 28MB on this card.

I have a two different 32MB sticks, 16 and 8MB sticks I've tried.

Chip with 16x TMS417409ADJ
MT16D832G is one of the 32MB, when I configure the SIMMCONN for 32MB I get 2MB (card has 512k native)
Configure for 16MB, get 2MB
Configure for 8MB double sided, get 8MB
Configure for 8MB single sided, get 8MB

I'm losing my mind here, any ideas on what might be causing this? I just ordered another 32MB chip with 16x GD 51H0112

Is it's possible its a resource conflict?

4th's time is a charm!

Did not work:
MT16D832G-6X Micron 32 MB SIMM DDR SDRAM Memory
Chips: Chips 16x MT4C4M4E

But the latest chip, assembled in Canada no less worked and passed!
Celestica 32MB EDO
Chips: GD 51H0112

Thanks for the help all!
