Question on RAM / motherboard compatability

Greetings:
I have a P4 Mainboard (#L4S5MG/651+) that accommodate 184-pin unbuffered DDR SDRAM.
I want to increase my memory up to it's full capacity of 2GB and would like to know if either of these boards would be best for compatability and performance.

thanks in advance for your advice.:wave

 

or

These two brands are the only ones listed that run at 400mhz (PC3200) and are therefore the fastest (actually DDR means Dual Data Rate so it's really 2x200mhz=400). Any brands of DDR should be OK in your motherboard, so get the fastest RAM for lowest price possible. Unless your motherboard is fairly old, you should have no problem running DDR400 at its full speed; if the MB can't handle DDR400, it will clock it down to DDR333 (or 266) if needed.

You can run the Crucial system scan and it will tell you what kind of memory works with your computer.
