i really don't know much. but i setup a desktop with below specifications to work at home. not for gaming. just running lot of CAD software n some virtual machine.

bought a : Corsair CMZ 8G X3M2A 1600C9 (suppose a 2 x 4GB DDR3, dual channel, 1600MHz / vengeance)

CPU : i5, 2400

Motherboard : ASUS P8B75-M LE (Chipset B75) the lowest end of ASUS i think

BIOS : American Megatrends Inc. ver. 0307

BIOS setting on memory speed : Auto

graphics : gigabyte NVIDIA GeForce GT 430, 2GB, 1600MHz (since 1600, should be not a factor of system RAM drop right? or does it even affecting?)

PROBLEM : why my CPUZ shows 'max bandwidth' at 667MHz only. should hav been 800MHz right even though BIOS set it to 667Mhz right? (since it's the 1600Mhz written on product should be the Max)



1. not gonna overclock my RAM since it will increase the voltage. or should i?
2. just want it to be optimized to it's normal speed.
3. what is XMP actually?
4. how do i read the memory timing?
5. what is really my RAM normal voltage 1.50V or 1.65V? (non exact model on latest QVL)

 
Solution
If u could get this...

$149.99

The default speed for your CPU is 1333MHz, so 667 is correct.

The XMP is preset overclock profile of the RAM in the RAM stick. U need to enable the XMP in the BIOS and it will run @ 1600MHz.

U also need RAM that is 1.5V

oh. so u were saying that i should customize my CPU speed? how should i?

troubling in posting some image of CPUz n QVL. it failed to appeared. already using the right script i think for image posting "

i did enable the XMP. but my desktop wont start up. i then pressed the MEMok button (resetting CMOS i believed) n got back on windows. what does that mean?

thought everythg gonna be just fine. instead... gonna change my RAM speed. if still don't workout then i'll try just use the regular setup (auto/default)

already done a :

1. activate XMP at 1600MHz - boot up - failed
2. activate XMP and reset at 1600MHz - boot up - failed
3. using only one stick & XMP at 1600MHz - boot up - failed
4. using only one stick - boot up - ok - but still 1333MHz

mainboard support 1600MHz FSB, DIMM 1600MHz Corsair CMZ-8G-X3M2A-1600C9. what am i missing?

CPU speed? suppose it will automatically run at 3.1GHz.

yeah. they all went OverTime trying to solved my problem n comes to an assumption that asus mainboard simply never stated that the maximum speed it support is the 2nd higher in the list. n with the OC stated. so even so my asus mainboard saying that it support to 1600MHz. they will just perform at max 1333MHz. so tomorrow i'm gonna get a new mainboard. had a problem with my sound system anyway. audio system keep unrecognized. money again.

wau. the community here in this forum is such a nice people.

but i already tried all that :

1. updated bios to 0407
2. resetting CMOS

anyway. Thanks a lot

getting a new asus mainboard, which one should i get. just a low end.

Option :

1. ASUS P8 Z77 - M
2. ASUS P8 Z77 - LX
3. ASUS P8 Z77 -LK

?
