As I listed above, the OCZ Low Voltage 2x2GB 1066 are the best value right now: http://www.amazon.com/OCZ-PC2-8500-Platinum-Voltage-OCZ2P1066LV4GK/dp/B002845LDC/ref=pd_rhf_p_t_1
I don't know of anyone that has gotten less than 1150+ 5-5-5-18 1.9v unless...
Get these instead: http://www.amazon.com/OCZ-PC2-8500-Platinum-Voltage-OCZ2P1066LV4GK/dp/B002845LDC/ref=pd_rhf_p_t_1
Cheaper and MUCH better.
Will run cas4 in your system.
Your Intel processor will give better performance with faster RAM. 1:1 is not optimal at all with Intel mobos. These are a great value right now and will run 1150+ 5-5-5-18: http://www.amazon.com/OCZ-PC2-8500-Platinum-Voltage-OCZ2P1066LV4GK/dp/B002845LDC/ref=pd_rhf_p_t_1
