Hello all
I Want to know that wil there be any problem if i use 2gb DDR3 1333mhz sticks into another slot my 1st slot already used by 2gb ddr3 1333mhz stick..cause my motherboard p5g41tmlx supports 1333mhz (OC) FSB and my cpu is intel pentium e5700 which is 800mhz FSB thats why my older ram downlocked 800mhz from 1333mhz now if i put same frequency ram will there be any booting issue ? or it will be downcloacked 800mhz like my older ram :) please assure me
 
Solution
Getting the same exact manufacturer and model of sticks will give you a better chance. The sticks will probably still need to be set up correctly in the BIOS to get the advertised speed.
Try it and see. Might be problems if the timings are different. You are taking a chance mixing sticks. Your best bet is to purchase a kit of 2x2GB 1333MHz memory. That way both sticks have been tested together to make sure they will work together.

1333MHz sticks will more than likely default to 1066MHz and will have to be set to the advertised speed of 1333MHz in the BIOS.
