RAM and Mobo

[wpan2002]

Well today i went to NCIX for some nice ADATA XPG 1.0 RAM and then when i get home i started my spare part build and when i am finished i click power on fast long beeps ... then i install a 1333MHz Kingston DDR3 RAM and then it post i think about it can i under clock the computer ram with the ram i have in now and switch it to the ADATA and then i can use it because i need it for school and the board i use the max is 8GB and i need it to run some bench marks for a school project and then i builded a computer and now i dont know how to underclock the RAM and i am worried if i under clock the ram would it underclock the cpu

i need to underclock the ram since the speed it too high and the motherboard dosnt want to post are do anything and i wonder if anyone can help me underclock it from 1600MHz to 1333MHz 

 

Core 2 Quad Q8300

GA-G41MT-S2PT

2x4GB ADATA XPG 1.0 1600MHz 1.5 Volt

ASUS GeForce GTX 550 ti

and a random ADATA SSD

 

and my case and psu i pick up was a combo the Cooler Master Elite 350 with a 500w psu in it and cooler master makes alot of my psu so i trust the builded in because they manufacture it them selfs

 

also this at the end will be in my hackintosh project for school

Are you sure about those specs.

AFAIK, LGA 775 motherboards only supported DDR and DDR2 Ram

 

I am wrong, you learn everyday!

Is it running dual channel? Have you selected the right RAM-Slots on your motherboard? Try it with a single stick of ram...
