I had a go at increasing the ram in my A320 tonight, and it worked. I removed the two SDRAM chips in there and replaced them with the same kind of chips as in the A330. This gives me 64MB of memory in my 320.

It was a tricky job, took about 90 minutes in total to do the swap, but I was lucky and it powered up first time. I put the A330 / 64MB Dingux on there and it instantly recognized the new memory.


You can see the memory info in the lower-left corner of the screen there... 62048k/65536k.

Detailed information, photos, and a full step-by-step procedure can be found on my blog.

Cheers!

I love you.

I wish I could be as useful and cool as you.  

Can you put the 330 LCD in there too? Maybe the shoulder buttons too, somehow?

If you have the A330 LCD, the same amount of RAM, AND the shoulder buttons from the A330, why don't you just buy the A330? Seems like a lot less work, if you ask me.

But that's no fun.

A truly great job you did Stephanie. 64Mb is the maximum of memory possible for the a320 or theorically you could increase to 128mb or even more?

I believe 128MB is possible, I've found a ram chip that appears to be compatible. It'd require a new SPL and new Dingux to take advantage of the added memory. The downside is a pair of these chips would cost almost as much as a 320, so not sure it's actually worth it. I have investigated the possibility though.

A screen swap would be easy compared to the memory chip hack. My white 320 doesn't need it though, it has a great screen. Bright and sharp, easily as good as the 330.

Re. the shoulder buttons, if the 320's shoulder buttons were a bit bigger that might help. You couldn't really move the microswitches but a case mod & bigger buttons might make them easier to use.

 

Wow, that's amazing!

that product page is confusing, they use MB where it should be Mb

any thoughts on whether it would work on an original dingoo, from back when the 9325 lcd was around, before any of this 'hk' crap...need a new one anyways

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.

Great job Stephanie! 

What have you paid for the ram?

What have you paid for the ram?

The ram chips cost me $6.17 each at DigiKey, plus shipping. It worked out to about $20 in total.

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

Ah I'm not looking forward to doing this again any time soon. It was stressful enough working on my own Dingoo, I don't think I could handle the stress of risking the death of someone else's Dingoo.
