MB: Asus M4A88TD-V EVO/USB3
CPU: AMD Phenom II X4 965 (NO O.C., on stock speed 3.4GHz)
RAM: 12GB DDR3 1333Mhz, 9-9-9-24
OS: Windows 7 Ultimate 64-bit

Hi, first of all I don't have much knowledge on the technical side of RAM, so I hope the following information isn't too bad.

I have this current RAM setup on the motherboard's DIMM slots. I recently added the 2 x 4GB sticks as an upgrade (I moved the original 2GB sticks to A2 and B2, and instead put the new 4GB sticks in A1 and B1:

DIMM A1 4GB
DIMM A2 2GB
DIMM B1 4GB
DIMM B2 2GB

All 4 RAM modules are Corsair XMS3s, and all 4 sticks are specified to run at 1333Mhz at 9-9-9-24, with a voltage of 1.50V.

Below are some screenshots:

- The 4GB modules info:

- The 2GB modules info:

Therefore taking the information in the above screenshots into consideration, I would like to ask the following questions:

1) On the 4GB module/stick information (second screenshot), how come the XMP-1334 column has a voltage of 1.600V? Is this correct, and will it limit the lifespan of the CPU?

2) Do I need to change this 1.600V to 1.500V in the BIOS?

3) Before I upgraded with the 2 x 4GB sticks, the first 3 Frequency columns in the Timings Table for the original 2 x 2GB sticks used to have higher frequency. How come after I added the 8GB of RAM these Frequency numbers has lowered?

4) Looking at the screenshots, if anyone can spot any flaws/problems and/or can improve, please advise. Remember I do not want to overclock anything as I have no need to.

Thanks in advance!
