Anyone ever tried adding larger capacity RAM chips?

No.

Thanks for clearing it up about the different revisions. I found a lot of old information on RAM regarding different versions compatibility. It is the case then, that all D, F, and M [QC-50] are compatible and interchangeable regardless of Xbox version?

There are many reports of non compatible pairings on the Internet but it is possible those reports were from faulty installations.

I don't think they make chips with more capacity using the same footprint.

I guess it must be reports from faulty installation or QC60+ chips.
Installing RAM chips that "can" go faster than the speed it's actually used is not a problem.
For example, in a PC, you can put DDR400 modules on a motherboard that only supports up to DDR333 speeds and already containing DDR333-rated modules without any problem. Both RAM sticks will work the same but the DDR400-rated one will be running at DDR333 speeds.

As I said earlier, I've been installing "F" chips along stock "M" chips on multiple Xbox revisions without any issue. I tested them all using SmartXX MemoryTester(and now mine too!) and Surreal64 CE.

Bu99er it, I'm gonna buy some and give it a go misself.

*** EDIT ***
...and so I did. I'll let you know when they arrive, and my next steps.

I've heard of people piggybacking RAM chips in other consoles etc, does anyone know if that's possible in the XBOX?

No, piggybacking isn't possible. The Xbox will only allow addressing of RAM up to 128MB.

Another source for new ram chips is here - http://www.utsource.net/

Hmmmmm... I'm sure I've seen Samsung items that were 32mb each... I'll take another look.... wish I still had my SMT station

Geeba, 128MB is the maximum. You are probably recalling bits or some other spec on the RAM.

Plus no program would use your RAM should you somehow get it working. It would be a lot of extra work desoldering all the working chips to replace with 8 new ones so even if it were possible almost nobody would get it hence no reason to develop for it.
