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?

Hello,

Does it beep at all with the 2 chips in it when you try to boot, or does it just simply lock up with no beep?

It's possible that one of the memory slots is bad.  You mentioned when you took one 2 GB chip out, it worked.  I'll assume that chip is in slot A.  Can you move that working chip to Slot B and leave slot A empty and does it still work?  If not, then Slot B is bad.

If it does work, then the chip you took out may be bad.  Try switching chips to see if it still boots.  If not, the chip is bad.  If so, then it may not like something about the memory speed.

I noticed that you chose slower speed chips (667 instead of 800).  Your original chip was faster and maybe the BIOS is expecting that speed.

Go in to the BIOS and under memory settings, toggle between dual channel mode and also indicate the speed of the memory you installed if applicable.

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.
