hi guys i have some doubts here currently i overclocked my i5 2500k to 4.3Ghz on air, the details are below

BLCK Frequency = 100
Turbo Ratio = By All Cores(Can Adjust in OS)
Internal PLL Overvoltage = Enabled
Memory Frequency = 1066Mhz
EPU Power Saving Disabled

Load Line Calibration = Extreme
VRM Frequency = Auto
VRM Spectrum = Disabled
Phase Control = Extreme
Duty COntrol = T.Probe Thermal
CPU Current Capability = 100%

CPU Voltage = 1.35
DRAM Voltage = 1.51
VCCSA Voltage = 1.00
VCCIO Voltage = 1.10
CPU PLL Voltage = 1.90
PCH Voltage = Auto
CPU Spread Spectrum = Disabled

CPU C1E = Disabled
CPU C3 Report = Disabled
CPU C6 Report = Disabled

maximum on idle = 43-49-43-46
maximum on stress(In Place Large FFTs) = 64-72-68-65 (1hour 25 minutes)

im using Noctua NH-CH14 and Artic MX4, ive checked others have done better than this, so am i doin someting wrong? hoping to get some enlightment here sweat.gif

the easiest solution is to re-tune the vcore.

Thanks mate, full stress 4.8Ghz @72C/lower will be my next target
However i'm happy with 4.3Ghz 1.17v  for 24/7, but i find out that when i running Cinebench, 3 core working very fast, but 1 core like freezing/extremely slow
Anyone have this issue?

I just bought Gskill Ripjaws X 1600Mhz... do i need to do anything to my i5 2500k to match the 1600mhz? Coz i remember i5 2500k default speed is at 1333mhz.

Edited: I had tried to run Prime95 for around 5 minutes, the CPUID gave the reading at max 70 Celsius and fluctuate at 69-70 celsius at native 3.4Ghz clock speed. Fan speed max at 2300rpm. Is this normal for Intel i7 2600 processor?

I will try to run Prime95 and see what's the highest temperature it will get, if not, i will try to recheck if my fan is seated properly.

Thanks again

try run intel burn test, rclxms.gif rclxms.gif
