It should work on an original dingoo. If you have a continuity tester, check pin 36 of the two ram chips. That's how I determined it should work - pin 36 is not at ground, and it is connected between the two chips. That pin is the extra address line that's not used on the 320's ram but is used on the 330's ram.

then i think i may have to try it, as soon as i get hold of a new soldering iron etc, and get the time

(though if you're thinking of modding any more, i'm very interested, sure we could work something out  )

Wow, well done!

i might have a go at this at some point. ill have to get some soldering practice first though

Ah I'm not looking forward to doing this again any time soon

fair enough, though it'd be a brand new one from dd-usa

guess i'll have to order a few chips, shame it says limited stock on the page...and i can't find anywhere else to get them

So I take you there 2x 16MB replaced with 2x 32MB chips - man this is to complicated for me to try lol,
If only you could stack the chips some how or make a mod chip style way of doing this 

a bunch of ram chips on their way to mine, have to borrow the universities surface mount equipment sometime 

Surface mount equipment? That's cheating!

You are correct, the originals were 2 x 128Mbit and were replaced by 2 x 256Mbit.

I did think about stacking them, but I don't think it would work. The original chips are seen by the CPU as a single grid of memory, with 32 bits, 12 rows, 9 columns, and 4 banks. Physically each chip is actually 16 bit, 12 row, 9 column and 4 banks; every 32-bit operation is divided between the two chips. The new chips just add a 13th address row, and that address line was already there anyways, just unused on the original chips.

I'm sure with enough thinking, it'd be possible to stack them, but it was just easier to replace them.

I don't know that stacking would be any easier anyways, these are TSOP-2 and the legs are pretty short, not to mention delicate and closely spaced. It'd be very easy to break one or leave a solder bridge or something.

Surface mount equipment? That's cheating!

aww dangit, but they've got the tiniest temperature controlled irons, 0.1mm solder etc etc...even a full reflow setup...guess i should try with off the shelf equipment first though XD got 4 chips so i can afford to fry a couple just about

Cool Bananas, Have you seen much of an improvement with the extra ram on dingux?
