Lenovo R61 laptop does not like 2 X 2GB RAM Chips

I have a Lenovo R61 laptop and it currently has 1-2GBDDR2 PC-800 RAM Chip in it.
It has 2 slots in the laptop.

I have installed 2 X 2GB DDr2 Corsair pc-667 chips into the laptop and it will not boot up.
If I take one chip out it boots.

I am presuming the issues is that the laptop does not like 4GB of RAM in it, however it should be able to take upto 4GB RAM.

I have upgraded the BIOS from the Lenovo website but no change.

Has anyone else experienced this?

Bank 1 works by itself with any chip. If I put a chip only in bank 2 it does not work. If I put 2 chips in it does not work. I am presuming bank 2 is faulty.

Went into bios -config- memory there is only one option for extended memory test

check the slot and clean it ( canned air and brush)
otherwise, looks like a bad slot

If nobus' cleaning suggestion does not work, then it's safe to say it's a faulty slot. You might check places like ebay or craigslist to find a used replacement motherboard.

test also both slots with the OLD ram

Second slot does not work with old ram either when in the second slot only. Must be bad slot
