Memory exchange on WL-500g

[Tamadite]

Does somebody knows the chances of getting a memory upgrade if I exchange the K4S641632H-TC(L)60 (4Mbx16) of my WL-500g by the K4S281632F-TC(L)60/75 (8Mbx16)?

Here you go the specs:

(4Mbx16)
(8Mbx16)

Possibly, if you can connect the extra line for addressing (A8). If you can get the schematic and/or trace the signal you can do abetter assesment..

On the GX it is possible.

You are completely right! Without A8 there is no way of addressing the extra 16Mb.

I can see all copper paths for the memory rows are available on the main-board so I wonder if they are enabled and if the BCM4702 is able to address them (A0-A8) to get the 32Mb.

I think of it is a matter of trying but I would like to have some more info.

For the Gx the schematic is in the CE&FCC reports. I don't know if those reports are available for the 500g.

On the Gx the extra line has to be connected by two jumpers(one to each chip).
