Nice first PC.
When you enter the bios
The options when you first enter the bios are as show.
At the top of the screen there will be the following options
Main - This contains the basic settings, e.g. time, date and what drives are connected to the computer
Ai Tweaker - this is where all the overclocking options are placed.
Advanced - This contains the options for USB configuration and CPU options, e.g. EIST and C1E
Power - This contains info such as suspend mode, this is also where you will find the hardware monitor
you can monitor the voltages and temperatures of your system.
Boot - This contains the options to change boot priority and Hard Disk priority.
What we will be focusing on is the Ai Tweaker part of the bios, this is where all
the settings for overclocking are located.
Once you enter the Ai Tweaker tab it will show up like this:
Ai Overclock Tuner - this option is for setting whether to manually adjust the fsb and ratio settings
for overclocking the CPU, We want this set to [Manual] so we can put in the frequencys we are wanting
CPU Ratio Setting - this is used to select the Ratio or Multiplier of the CPU, this varies depending
on what CPU you have. For you it's 9x multiplier
FSB Frequency - this is the frequency of the Front Side Bus, this is used to determine the speed of the
CPU. For example, if you set this to 400 and you had the Ratio CMOS Setting set to 9x, this would cause the
CPU speed to be 3600Mhz or 3.6Ghz.
PCIE Frequency - This slightly boosts your graphics performance. However, anything set over 120 can corrupt
your hard drive, It is recommended to set this to 105.
FSB Strap to North Bridge - this is the strap the northbridge and the FSB share, it helps determine what
memory frequency we will use. It is recommended to set this to 333 for most of the latest cpus
DRAM Frequency - This is the frequency the RAM will be operating at, for most people it is recommended
to select the first option.
DRAM Timing Control - this is used to determine what timings the memory will have, this depends on what
your memory is capable of. This will be listed on your memory packaging. If you cannot find them, you
can leave this on Auto - If you do know the timings, relative to what you set in the DRAM Frequency
you can set the timings of your ram.
If you are new to overclocking, you will not have to worry about these for now. These will be explained
in more detail later in this guide.
DRAM Static Read Control - Auto
DRAM Read Training - Auto
MEM. OC Charger - Auto
Ai Clock Twister - Auto
Ai Transaction Booster - Auto
- 65nm CPUs, the E6xxx series and Q6xxx series cpus it is save for 24/7 usage to go up to 1.5v
- 45nm CPUs, the E8xxx and Q9xxx series, it is recommended to only go up to 1.4v, anything above that
can cause gradual degradation. Meaning it will slowly kill itself.
CPU GTL Reference - Auto
CPU PLL Voltage - For any gradual overclock with a dual core, you can leave this on Auto, but for any
Quad Core CPUs, it is recommended to set this to 1.6v, the stock voltage is 1.5. This can help with
overclocking a quad core.
FSB Termination Voltage or VTT - it is recommended to keep this under 1.4v for any 24/7 setup
as this can also cause degradation on 45nm cpu's. Setting this to 1.3 can alleviate any bottleneck
it might cause, as well as still being safe.
DRAM Voltage - This depends on what voltage your memory comes stock with, this can range from 1.8-2.4v
depending on the speed and timings of your RAM. It is recommended to stay below 2.2v with active cooling
(having a fan blowing over top of the ram). But it is also recommended if you want to keep your warranty
of your ram, to keep to the stock voltage.
North Bridge Voltage - As the DRAM frequency is controlled here, it can help with FSB overclocking
it is recommended to stay under 1.6v for any 24/7 usage.
South Bridge 1.5 Voltage - You can leave this set to Auto
PCIE Sata Voltage - Auto
Load-Line Calibration - Enabling this can help with vDroop.
vDroop is the voltage drop of the cpu, e.g. you could set 1.4v in bios and then in windows you will find the
voltage will be set to 1.37v, meaning that you have a vDroop of 0.03v. This can increase also when you are
putting a load onto the CPU. If the voltage drops to low, it can cause system insability, as it will not supply
enough voltage to the CPU, making it unstable.
It is recommended to have this set to [Enabled]
CPU Spread Spectrum - Auto
PCIE Spread Spectrum - Auto
CPU Clock Skew - Auto
NB Clock Skew - Auto
MB Clock Skew - Auto
This explains the basics of the settings for overclocking on the P5Q Pro Motherboard
Here are some settings that can be used to achieve a stable overclock
Settings for Q660 for 3.6ghz - should be possible for every Q6600
Ai Overclock Tuner : Manual
CPU Ratio Setting : 9
FSB Frequency : 400
PCIE Frequency: 105
FSB Strap to North Bridge : Auto (p5q pro has some problems with straps)
DRAM Frequency: Auto, this will be set to 848Mhz (or change to the mhz of your memory)
DRAM Timing Control: Auto (adjust to your timings of your memory)
DRAM Static Read Control: Auto
Dram Read Training : Auto
MEM OC Charger : Auto
Ai Clock Twister : Auto
Ai Transaction Booster : Auto
CPU Voltage : Set what you need, this will range from 1.20-1.4v
CPU GTL Reference: Auto
CPU PLL Voltage : 1.50
FSB Termination Voltage: 1.30
DRAM Voltage : 2.1
NB Voltage : 1.2-1.5v (quads are alot harder than dual cores to clock, the NB voltage helps with the higher FSB on quad)
PCIE Sata Voltage: Auto
Load Line Calabration : Enabled
CPU Sread Spectrum : Disabled
