i5-2500k OC to 4.3Ghz

post #1 of 2
Thread Starter 
Hello,

Does anyone have a step by step guide to overclock a i5-2500k cpu to 4.3ghz? I've read that all you need to do is change the multiplier to x43 and turn off all the power saving features and leave everything else to "auto". I'm pretty new to OCing so I'm not really sure what all the power saving features are yet. Also, what's a safe/stable vcore for a 4.3 OC? This is what I have so far... I'll bold anything I don't understand when it comes to OCing to 4.3ghz.

but, before I do that, I'll post my build;

- Asus P8Z68-V Pro
- Intel i5-2500k
- G.Skill Ripjaws X Series DDR3 1600Mhz C9 1.5V 8GB(4x2)
- Thermaltake Frio
- Corsair Enthusiast Series TX850

- Set "Ai Overclock Tuner" to "Manual"
- Leave "BCLK/PEG Frequency" to "100.0"
- Set "Turbo Ratio" to "By All Cores"
- Set "By All Cores(Can Ddjust in OS)" to "43"
- Set "Internal PLL Overvoltage" to "Enabled"(I've read that you only enable this if you're running 48x and above?)
- Set "Memory Frequency" to "DDR3-1600Mhz"
- Set "EPU Power Saving Mode" to "Disabled"
- Set "OC Tuner" to "Cancel"

- Set "DRAM Timing Control" all to "Auto"

- Leave "CPU Power Ratio" to "Auto"
- Set "Intel Speedstep Technology" to "Enabled"
- Leave "Turbo Mode" to "Enabled"

- Set "Turbo Mode Parameter" all to "Enabled"

- Set "Load-Line Calibration" to "Extreme"(I've seen a lot of people run this on "Ultra High" so I'm a bit confused on this part)
- Set "VRM Frequency" to "Auto"(I've also seen this set to "350". Not sure what the difference is)
- Set "Phase Control" to "Extreme"
- Set "Duty Control" to "Extreme"("I've seen people run this on "T.Probe". I've read you use T.Probe for 48x and above?)
- Set "CPU Current Capability" to "100%"

- Set "CPU Voltage" to "Manual Mode"(Do I switch this to offset once I find a stable vcore?)
- Set "CPU Manual Voltage" to "??"
- Set "DRAM Voltage" to "??"
- Set "VCCSA Voltage" to "??"(Do I leave this to "auto"?)
- Set "VCCIO Voltage" to "??"(same as above)
- Set "CPU PLL Voltage" to "??"(same as above)
- Set "PCH Voltage" to "Auto"
- Set "CPU Spread Spectrum" to "Disabled"

- Set "CPU Ratio" to "Auto"
- Set "Intel Adaptive Thermal Monitor" to "Disabled"
- Set "Active Prosessor Cores" to "All"
- Set "Limit CPUID Maximum" to "Disabled"
- Set "Execute Disable Bit" to "Enabled"
- Set "Intel Virtualization Technology" to "Disabled"
- Set "Enhanced Intel Speedstep Technology" to "Enabled"
- Set "Turbo Mode" to "Enabled"
- Set "CPU C1E" to "Enabled"(I've read enabling these causes instability issue but disabling it causes HDD issues"
- Set "CPU C3 Report" to "Enabled"(Same as above)
- Set "CPU C6 Report" to "Enabled"(Same as above)

- Set "CPU Q-Fan Control" to "Disabled"
- Set "Chassis Q-Fan Control" to "Disabled"
- Set "Anti Surge Support" to "Enabled"

Any input would be greatly appreciated. I've been reading up on this for hours and I just want to make sure I'm doing everything right before I start.

Thank you.
