Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K June 2013
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K WARNING Altering clock frequency and/or voltage may (i) reduce system stability and useful life of the system and processor; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel has not tested and does not warranty the operation of the processor beyond its specifications.

Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K 1 Overclocking Assistant 1.1 Objective The Purpose of this performance tuning guide is intended for validation and system characterization purposes only. The setting in this document is not fully validated and may not function across all the available K-processors. It is assumed that CPUs in the same family will have common settings. The new feature of the 4th Generation Intel ® Core processor is an integrated voltage regulator (IVR).
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K There are 3 settings for this voltage: Offset only, Interpolated + Offset and Static + Offset. The Offset Mode: Positive and negative offset applied to the entire curve.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K The Interpolated Mode: Sometime is referred to Adaptive mode. This is only applicable for frequencies and voltages beyond the default maximum turbo frequency.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K Static + Offset Mode: This Static and Office mode (Override mode) is useful when overclocking or underclocking the BCLK. This method can allow for adjustment of the entire V/f curve. 2. The other main voltage that can affect the ability to overclock is SVID override (Input Voltage below). The default for this voltage is 1.7v ~ 1.8v on the Intel® Desktop Board DZ87KLT-75K.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K Over-current protection (OCP) will be masked. Reliability of the processor should be concerned by possibly overvoltaging inadvertently. In turbo mode or BCLK OC, the Processor VR efficiency is set to disable (uncheck). It will force IVR to always run in max power delivery capability mode. When raising BCLK frequency, this Filter PLL should be set to Low Speed mode.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K Clock PLL: For Turbo ratio overclocking, set to LC-PLL; For BCLK, set to SB-PLL. Use the option below for BCLK overclocking with PEG/DMI ratio. The PEG/DMI ratio will automatically change when you adjust the BCLK. Notes: To adjust the Manual settings, uncheck Automatic PEG-DMI Ratio. In manual control you can adjust the BCLK by 4% to 5% for upside frequency and you can achieve a larger down frequency range.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K 2 Kinsley-75k using Turbo Ratio OC 2.1 Tuning Tab/Performance Settings Under the Tuning Tab/Performance Settings: 2.2 Check the Unlock Extreme Voltages setting if it is not checked (if you have a K-skew CPU, this should always be checked) Uncheck the Processor VR Faults setting (disable). Uncheck the Processor VR Efficiency setting (disable).
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K Set Burst Mode Power Limit 1000. Set Sustained Mode Power Limit 1000. For Example: On Cores > Slide or type to 42 (100 MHz x 42 = 4.2 GHz).
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K 12 On Ring >: Slide or type to 42 (Ring multiplier can set the same or lower than Core, but not higher than Core). Exit and Save.

Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K 3 Kinsley-75k using BCLK OC 3.1 Tuning Tab/Performance Settings Under Tuning Tab/Performance Settings: Check Unlock Extreme Voltages if not check (if you have a K-skew CPU, this should always be checked). Uncheck Processor VR Fault (disable). Uncheck Processor VR Efficiency (disable). Change Clock PLL from LC-PLL to SB-PLL. Make sure Filter PLL is set to Low Speed. Set BCLK to 125.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K Select the red square box on the left. Change Processor Ring Voltage Mode to Static + Offset. Raise Processor Ring voltage target to 1.24v. Change Performance Memory Profile from Automatic to Manual-User Defined.
Overclocking Assistant for the Intel® Desktop Board DZ87KLT-75K 16 Change Memory Multiplier to 8. If use onboard graphic. Need to change the Graphic offset to 0.10v. Save and boot to windows. Note: Board might need to be rebooted or reset twice.
