overclock i7 2600k cpu

[Hunter-]

Hi all.I decided to overclock my CPU i7 2600k sandy bridge to 4.0 ghz and im wondering if voltages on processor are ok,and if my overclock seems to be fine.Also I mentioned I have air coling,not water.I have Zerotherm Nirvana NV120 Premium
My motherboard is asus p8p67 pro rev 3.1 and the setting for overclock :
1.Advanced
-CPU Ratio- 40
-Enhanced Intel Stepside-Disabled
-Intel adaptive thermal monitor-Disabled
-Turbo Mode-Enabled
-Intel Virtualization-Disabled
2.Tweaker
-EPU power-Disabled
-memory freqwency-here I don t now if I let to 1333 or 1600 MHz
-dram timing- ? ? ?
-CPu PLL Voltages 1.800 v ?
3.Load Line calibration
-vram freq -Extreme
-phase control-auto
-Duty control-Extreme
CPU voltage-1.20V, 1.31V-Manual Mode -I wondering if these voltages are OK,or if are high
Dram Voltage-1.509 V
save changes and reset!

Plese tell me if this manual overclocking are fine,if voltage memory are ok and if I need higher memory ram.For the moment I have 1333 MHZ memory

What are your load temperatures? Also, is it stable under load with lower voltages?

That's fine. You should be able to go up to 1.3v with your cooler.

Dram Voltage-1.509 V

CPU ratio: fine.. bit low though imo 44x should work at 1.3v on most 2600ks

Set 1600MHz

9-9-9-24 should work on most kits as ram timing

Set phase/duty control to optimised.. you dont need extreme for this kind of co

CPu voltage fine

DRAM voltage fine

if I set to 1600mhz dram my system go to sleep mode.Don t work.Maybe I need RAM memorie with at least 1600 MHz?My ram have only 1333 MHz and don t let me to overclock because is blocking my system

Also with 4 ghz on CPU I can t see any diference of performance in games.I can t see even 1 frame boost.Same result in benchmark like 3.40 ghz stock speed

Stick with 1333 then

 

some games dont need more cpu speed, some do
