The current ram is ddr2 553 I replaced 2 of the 4 slots with DDR2 667.
The mother board can take 667, 533, or 400; according to the support documents.
The mother board is an Intel 945G ICH7R.

After installing the second pair of 667 I will change the speed bios settings. How should I do that and is there anything else I should do to use the RAM full capacity?

Hello... if you you are planning on using both pairs of 553 and 667... your Ram speed is still limited to the slowest Ram speed installed... making the 533 Ram run at 667 could cause you problems in time.

Go into the BIO's and find the option to change Ram speed and re-boot.

The spec sheet only says "Intel (Big Lake) 945G Motherboard", but I will check out the site you posted when I get home.
I am going to upgrade the other two RAM so I will wait until they are installed before switching the speed to keep it consistent.

Hello... PLEASE!!!! don't invest alot of your time and $$$ into getting that RAM speed upgrade or compatability... You will not notice it at all... What is important is the amount of ram you add to your SYSTEM. You could use DDR2 800... it is backward compatable.
