Asus P5Q3 Deluxe WiFi@N & TW3X4G1600C9DHX Settings


Recommended Posts

You have to perform a slight overclock of the CPU FSB to attain the necessary 1:1 ratio of CPU:DRAM. Drop the multiplier from 9.5 to 9 which will give you 3.6Ghz and the proper 1600Mhz DRAM speed due to the 400Mhz FSB. If you drop the multiplier to 8, then you will have 8 X 400 ~=3.2Ghz which is very close to the stock speed of the CPU. However, I would go with 9 X 400 = 3.6Ghz and which your CPU can do with stock CPU Voltage.

Download Memtest86+ V2.01 from--->

Download CPU-z from

Download Real Temp from-->

Enter your BIOS. Load Setup Defaults. Save Setup Defaults. Set to these values:

Boot to the Memtest CD and 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. Finally post a screenshot of Real Temp.
