Here is another quick guide that may help you to maximize your CPU performance :) Before starting this guide make sure to download the latest BIOS for your motherboard!
For this guide I used the following:
- Intel Core i7 3960X
- EVGA X79 SLI
- EVGA Superclock CPU Cooler w/ LGA 2011 Mounts
1. Firstly, go into the BIOS by pressing the Delete
key when the system is posting. Head over to the Save/Exit
section and select Restore Defaults, next select Yes. This will ensure we are starting with a fresh BIOS setup:
2. Next, head over to the Overclocking
tab. Here we will make a few adjustments:
- CPU Multiplier Setting set to 46 - This is our CPU frequency. Since the default BClock is 100MHz; 100x46 = 4600MHz or 4.6GHz. This is the option we will use to configure our CPU Frequency. On X79 we also have the ability to set BClock Ratio (BCLK Frequency Ratio) of 1.00, 1.25, 1.57, etc. We will not cover BClock Ratio's in this guide, but it is another option to increase CPU frequency. Note: We have seen a good number of CPU's that are able to hit this frequency, but your CPU may vary.
- VDroop set to Without VDroop - This will help keep our CPU voltage stable and reduce voltage sag under load.
- CPU VCore Control Set to Fixed - You can choose to set a Fixed Voltage, or use CPU Offset's.
- CPU VCore set to 1.400V - In this guide we are going to start at 1.4V, this may vary depending on your CPU. This needs to be typed in manually in mV. (ex 1.4V = 1400mV)
- DIMM Voltage set to Varies - Set your DIMM voltage to manufacturer recommended spec. You can set seperate DIMM voltages for each memory bank.
3. Now we will configure some of our CPU settings, the options in this portion are completely optional. If you wish for your CPU to use Intel Speedstep Technology, which saves on power by downclocking when the system is idle, skip this section. For this guide we are configuring our CPU to run at full performance at all times. Head over to the CPU Core Ratio Control Section.
- C1E, C3, C6 and C7 set to Disable - These are powersaving features.
- EIST set to Disable. This is Intel Speedstep Technology.
- DO NOT DISABLE TURBO MODE! This essentially allows your CPU to OC at all!
4. This step is completely optional, you can save a BIOS Profile in the Save/Exit section and call it whatever you like. This is useful incase you need to reset your BIOS settings or make changes you can always load your presets easily.
5. Now it is time to Boot into Windows! Select Save Changes and Exit
, and your system will boot. Make sure to keep a close eye on your CPU temperatures. TIP: You can look at the debug LED on the motherboard to see your CPU temperature:
6. Now that we are in Windows, we will run a CPU Stress test. Ex: LinX, Prime95 or 3DMark CPU test. We can check our CPU frequency by using the EVGA ELEET Utility. www.evga.com/eleet
7. If it completes with no failures, we can reboot, go back into the BIOS, and increase the CPU multiplier 1x at a time.
8. You may need to experiment with increase the CPU Voltage if you have issues with system stability, remember to take it a step a time, and keep an eye on those CPU temps! Increasing CPU Voltage will likely increase your CPU temperature. You can also try enabling the ELEET Ratio Control in the BIOS, and use ELEET to increase the CPU multiplier one step at a time.
9. Once we find an acceptable CPU frequency, we can use the EVGA ELEET utility to save a validation, and upload it for the world to see!
