i5 2500k at 4.8 please help

post #1 of 5
Thread Starter 
so i got my new h 80 and is working great ( i think)
so i run prime 95 with 1.370v and it crash with the blue screen after 1.45min
again with 1.375v and it crash after 2:20min
again with 1.38 and it crash after 1:20min

i dont understand why it crash in less time on 1.38v.
i have all c-states off
and turbo boos power limit at 120/120 /1
what should i do to run prime 95 more than 12 hours???
my max temp with prime 95 full load with cpu cooler h 80 is 71c and 63-66c always running. so what now??

I recommend trying these settings and then tweaking forward from there:

Ai Tweaker
  • Ai Overclock Tuner: Manual
  • BLCK/PCIE Frequency: 100.0
  • Turbo Ratio: By All Cores
  • By All Cores: 48
  • Internal PLL Voltage: Disabled
  • Memory Frequency: use the rated speed for your memory
  • DRAM Timing Control: use the rated timings for your memory
  • EPU Power Saving MODE: Disabled


Ai Tweaker\\ CPU Power Management >
  • CPU Ratio: Auto
  • Enhanced Intel SpeedStep Technology: Enabled
  • Turbo Mode: Enabled
  • Long Duration Power Limit: Auto
  • Long Duration Maintained: Auto
  • Short Duration Power Limit: Auto
  • Additional Turbo Voltage: Auto
  • Primary Plane Current Limit: Auto


Ai Tweaker (in the DIGI+ VRM section)
  • Load-Line Calibration: Ultra High
  • VRM Frequency: Manual
  • VRM Fixed Frequency Mode: 350
  • Phase Control: Extreme
  • Duty Control: Extreme
  • CPU Current Capability: 140% (it's supposed to turn red in the UEFI)
  • CPU Voltage: Offset Mode
  • Offset Mode Sign: +
  • CPU Offset Voltage: 0.040V
  • DRAM Voltage: use the rated voltage for your memory
  • VCCSA Voltage: Auto
  • VCCIO Voltage: 1.15625V (using VCCIO Voltages in between 1.100V and 1.200V may help enable you to lower the vCore while maintaining stability)
  • CPU PLL Voltage: Auto
  • PCH Voltage: Auto
  • CPU Spread Spectrum: Enabled


Advanced\\ CPU Configuration >
  • CPU Ratio: Auto
  • Intel Adaptive Thermal Monitor: Enabled
  • Active Processor Cores: All
  • Limit CPUID Maximum: Disabled
  • Execute Disable Bit: Enabled
  • Intel Virtualization Technology: Disabled
  • Enhanced Intel SpeedStep Technology: Enabled
  • Turbo Mode: Enabled
  • CPU C1E: Enabled
  • CPU C3 Report: Auto
  • CPU C6 Report: Auto



Note: that Offset Voltage of 0.040V gives me a Core Voltage in CPU-Z of about 1.384V - 1.392V while under full load in Prime95's Blend. So be cautious and adjust accordingly.

If these settings don't work for you, then try an Offset Voltage of 0.045V.

If a BSOD occurred, then it would be harmless because at that point it would just be sitting there idling.

Anyway, nice results and nice temps!
