Subject. Has anyone done similar experiments?

128 MB is, of course, good. Now a few questions:
• about replacement with chips of more than 128 (256 etc.) MB nothing is known?
• Infineon HYB25L512160AC-7.5 chips are used in PDACenter. How much can such chips cost?
• did anyone do such an upgrade?

Chips larger than 128MB may not be supported by processors, for example, for Intels 27x, the limit is 128MB.
Independently this can be done only with the necessary equipment at home (hair dryer, stencil, etc.)

Thanks for clarifying. The first question was dropped :)

Well, it's understandable :) not to work with a soldering iron: D

Here is a competitor. In Moscow.

Slightly more expensive (3000rur), but it seems that the PDA nomenclature is larger.

They devour the earth, which they do almost in the presence of the customer, but recommend them to pre-telephone

Rave. The PXA27x supports more than 128 MB of RAM memory. In one mode, a maximum of 384 MB, in the other I do not recall.
The problem is that there are no larger chips that could be installed instead of the old ones.

Read the datasheet, there is clearly and clearly written -128mb maximum.

[Cotulla]

And where is?
Specially for you I spent 5 minutes and checked: "Interfaces to up to 1.0 GBytes of SDRAM"
so this is nonsense for 128mb.

[Jager]

Both are wrong: lol:
PXA27x supports up to 4 partitions of 64mb, totaling 256mb

128mb maximum.

Cotulla @ 26.7.09, 21:25

"Interfaces to up to 1.0 GBytes of SDRAM"

Jager @ 27.7.09, 12:23

up to 4 sections of 64mb, total 256mb

Um .. and who to believe? o_O

Interesting, and in the firmware somewhere there is an infa about the amount of memory? those. If you change the 64MB chip to 128MB, will you have to edit the firmware or will it all work?

[POM @ 777]

NX_MINI,
It seems for asus p750 there is a separate firmware for 128 meters.

Something tells me that there is such compatibility, but definitely not everywhere.

[Holips]

Eh ... it would be great to replace the chip with another with a large volume. It happens, you look at some devices, you read: and that is, and this, and the third ... And operatives, as for evil - 64 meters. Here chip tuning and helps out. And again problemma - all in Moscow and in St. Petersburg. And about the regions forgets. Here I sit, read posts and bite my elbows! : rofl:

[drum1k]

Holips,
In the regions they also seem to do

[hanxxx]

alex07111971,
and can be more?
did you disassemble the machine after tuning?
pictures in the studio

[Maverick1968]

I disassembled the Qtek S100 after tuning .....
chips were shot there at 32 mb (2 pieces) and chips were put at 64 mb (also 2 pieces)

On Mitka a700 is it possible?
