ASUS P5Q3 Deluxe Wi-Fi and TWIN3X4096-1600C7DHXIN stable bios configuration?


Recommended Posts

Thanks for replying! I'll check the FAQ.

I don't OC and my question is just simple. I want to run my memory at 1600mhz and my pc to stay stable. I bought this memory because at the Corsair memory configurator this memory was compatible with this board. So it's natural to expect that is tested and is working with no errors at 1600 mhz because otherwise will not be in the list (?) or at list will be stated to work at 1066mhz only. I'm looking only for stability with highest possible clock for the memory (1600mhz will be enough for me:winking:)

You have to perform a slight overclock of the CPU FSB to attain the necessary 1:1 ratio of CPU:DRAM. Insert a single stick of DRAM in Slot 2. Restart the system and enter your BIOS. Load Setup Defaults. Save Setup Defaults. Set to these values:


[b]AI Overclock Tweaker[/b]

[b]Configure Advanced CPU Settings[/b]

CPU Ratio Setting = 9
C1E Support = Enabled

Configure System Performance Settings

Ai OVerclocking Tuner = Manual
CPU Ratio Setting = 9
FSB Frequency = 400
PCIE Frequency = 100
FSB Strap to North Bridge = Auto
DRAM Frequency =  DDR3-1600MHz
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 

[b]Primary Information[/b]

CAS# Latency = 7 DRAM Clocks
DRAM RAS# to CAS #Delay = 7 DRAM Clocks
DRAM RAS# Precharge =  7 DRAM Clocks
DRAM RAS# Activate to Precharge = 20 DRAM Clocks
RAS# to RAS# Delay = Auto
Row Refresh Cycle Time = Auto
Write Recovery Time = Auto
Read to Precharge Time = Auto

[b]Secondary Information[/b]

Read to Write Delay (S/D) = Auto
Write to Read Delay (S) =  Auto
Write to Read Delay (D) = Auto
Read to Read Delay (S) = Auto
Read to Read Delay (D) = Auto
Write to Write Delay (S) = Auto
Write to Write Delay (D) = Auto

[b]Third Information[/b]

ALL PRE to ACT delay = Auto
ALL PRE to RED Delay = Auto
DRAM Static Read Control =  Disabled
DRAM Dynamic Write Control =  Disabled

DRAM Voltage = 1.8v
NB Voltage = 1.35v

CPU Margin Enhancement = Optimized


Shut the system down. Insert the second stick in slot 4 and boot to the Memtest CD. Allow for two full passes. Then, if stable, enter Windows and run CPU-z. Post screenshots of CPU-z's CPU, Memory and SPD tabs. This will give you 9 X 400 = 3.6Ghz and should not necessitate any voltage raises other than the DRAM and a light MCH increase.
