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?
