Changing DDR2 ram

Post by vtailor »

I keep puzzling over how you solder ram to the computer board in the fit-pc2, and what you do if the piece of ram fails tests afterwards; and I keep coming up with the answer that 200 pins are a lot of pins, and I have never seen a piece of ram sold as a computer part with 90-degree angle pins. I will probably have to buy a fit-pc2 and deliberately void its guarantee by taking the case apart to verify that there is no conventional piece of DDR2 ram plugged into a 90-degree, close-fitting socket.

Best regards to the sexton, and he is welcome to delete this post.

The DDR2 is soldered directly on-board chip by chip (8 chips overall) in a similar manner to the RAM soldering in many mobile devices.
Each chip is similar to the one you would find on an SODIMM RAM.

See http://compulab.co.il/wp-content/galler ... itpc2i.jpg
4 chips on the left side are the DDR2 (another 4 are on the other side).
It may save you opening the fit-PC2...

In fit-PC3 and Intense PC we opted for standard SODIMM modules which are user-accessible.
