When you populate all four DRAM slots it is advised to drop the bandwidth.

 

Please research this thread:

The issue is the On Motherboard (Intel) memory controller and a population of all four banks at the full speed of a two bank run. This issue is across the board with both Nvidia and Intel chipset based boards, DDR, DDR2 and DDR3.

 

Keep in mind that often issues arise in the longer term. The issues seldom damage the DRAM. They damage the on motherboard memory controller which has a harder time keeping up with the demands of a four DRAM slot population being run as fast as a two DRAM slot population. Those who want to be secure in their system either purchase a single kit of the DRAM capacity that the four singles have or they move to a higher bandwidth DRAM and drop the bandwidth. I also advise it as I have personally seen the issues that can and often do arise with a four DRAM slot population running at the full speed of a single kit speed.

 

I personally advise for a two stick solution as it is far gentler to the motherboard memory controller.

 

Download memtest from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from
.

Enter your BIOS, Load Setup Defaults, Save Setup Defaults and set to these values:

AI Overclock Tweaker

Configure System Performance Settings

Ai Overclock Tuner = Manual
CPU Ratio Setting =333
PCI-E Frequency = 100
FSB Strap to Northbridge = 333
DRAM Frequency = Manual
DRAM CLK Skew on Channel A1 = Auto
DRAM CLK Skew on Channel A2 = Auto
DRAM CLK Skew on Channel B1 = Auto
DRAM CLK Skew on Channel B2 = Auto

DRAM Timing Control = Manual
DRAM Frequency = DDR2-800
DRAM Command Rate = 2N
DRAM Timing Control = Manual
CAS# Latency =  5
RAS# to CAS# Delay = 5
RAS# PRE Time = 5
RAS# ACT Time = 15
Row Refresh Cycle Time (tRFC) = 55 
All Else to Auto

DRAM Static Read Control = Auto
DRAM Read Training = Auto
Mem. OC Charger = Auto
AI Transaction Booster = Auto

CPU Voltage = Auto
CPU PLL Voltage = Auto
FSB Termination Voltage = Auto
DRAM Voltage = 2.1v
NB Voltage = 1.40v
SB Voltage = Auto
PCI-E SATA Voltage = Auto

Loadline Calibration = Auto
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled

Clock Over-Charging Voltage = Auto
Load Line Calibration = Auto
CPU GTL Voltage Reference = Auto
NB GTL Voltage Reference = Auto

Memory Remap - Enabled

Legacy USB = Disabled (For Memtest, Enabled After Memtest)

 

Run Memtest for two full passes. When assured of stable DRAM, then enter Windows and Run CPU-z and post screenshots of CPU-z's CPU, Memory and SPD tabs.
