Brukar vara dåligt å köra turbo speed och överclocka med den på. Volten blir galet högt. gjorde så med min 3770K och då satte jag den i turbo sen drog jag upp volten +0,010 och sen när jag kollade på CPU-z så var volten på hela 1,3v! Men när jag stänger av turbo mode och sätter volten på +0,040. så är den 1,186-1,216v och det det är helt lagomt för en Ivy bridge. Så stäng av Turbo och kolla en guide på youtube!

Här har en skrivit vad han kör sin 2500K på för settings, alla moderkort ser ju olika ut i BIOS men det står ju nästan samma sak som på andra modeller. Lycka till med denna CPU då :
That is from Theocnoob's guide on OCing Sandybridge CPUs.
I don't have an aftermarket cooler yet (will probably grab the 212+ or 212 EVO), but I couldn't resist the urge to get a headstart and since my current "cooling" is limiting me to around 4.0Ghz, I figured I would post what I had experienced in that range.
My temps were going into the 80's at 4.5, so I pulled things back a bit.
I am now at 4.0, working my way down through the voltages.
One thing I found helpful were posts detailing the BIOS settings of other users, so here are mine...
BIOS settings with Asrock Extreme3 Gen3 are:
Under "OC Tweaker"
Advanced Turbo 50 - Disabled
Load Optimized CPU OC - Disabled
CPU Ratio Settings - Manual
Max Ratio - 40
Internal PLL Overvoltage - Disabled
Intel Speedstep Tech - Enabled
Turbo Boost Power Limit - Manual
Short Duration Power Limit (W) - 200
Long Duration Power Limit (W) - 200
Long Duration Maintained (Sec.) - 1
Additional Turbo Voltage - Auto
Core Current Limit - 300
BCLK - 100.0 Mhz
Spread Spectrum - Disabled
Power Saving Mode - Disabled
CPU Core Voltage - Fixed Mode (kör den på Offset mode och ändra själv, mycket tryggare)
Fixed Voltage - 1.260V
CPU Load-Line Calibration - Level 2
DRAM Voltage - 1.672
PCH Voltage - 1.059
CPU PLL - 1.832
VTT - 1.047
VCCSA - 0.925
Under "Advanced\CPU Config"
Active Processor Cores - All
Hardware Prefetcher - Enabled
Adjacent Cache Line Prefetch - Enabled
Enhanced Halt State(C1E) - Enabled
CPU C3 State Support - Enabled
CPU C6 State Support - Enabled
Package C State Support - Auto
CPU Thermal Throttling - Disabled
Intel Virtualization Technology - Disabled
No-Exec Memory Protection - Disabled
-------------------------
Though my CPU voltage is set at 1.26V, the average during my Prime runs is about 1.18V. Does anyone know what BIOS setting controls this fluctuation? Or is it something that just happens?
Temps in P95 are in the 70's and never go into the 80's. I would assume these could be much lower had I taken off the stock TIM and reapplied my own, but I figured I was replaced the cooler soon anyway.
I'll keep trying lower voltages and post results.
If anyone has anything to add, feel free. These BIOS settings are all new to me, so if I have something disabled/enabled which you feel could be changed for the better, let me and other know.
