Rebuilding HP Laptop 2000 series with A7A74UA motherboard

I'm replacing a bad motherboard in my 2000-412NR notebook with a different motherboard (orign657324-001 with a 657323-001).  They both look physically the same.  I understand that the 657323-001 has a slightly better processor, E-450 versus the original E-300) which is why i decided to go with it since i need a replacement anyway. 


The Notebook 2000-418US,which uses motherboard 657323-001 (A7A74UA), says the maxiumum memory is 8Gb (as does my original Notebook 2000-412NR).  I'm guessing this is because at the time of manufacture, 8Gb modules weren't available.  I also see that HP says I can replace my PC3-10600 modules with PC3-12800 ones (on both motherboards).


My question is,  can I use 8Gb RAM modules, and max my laptop out at 16Gb versus 8Gb, or is there a BIOS issue?  Also, does it matter whether I use 1.5V or 1.35V memory modules?

Hi Aellixson,


Welcome to the HP Forums!


For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.


When I checked the HP 2000 Notebook PC Maintenance and Service Guide the motherboard you are replacing the orignal with is listed on page 19 under item 11.  The PC3-12800 replacement only support 8GB total the same as the original motherboard.  I hope this has answered your concerns.
