Hej
Tycker du ligger lite högt för 24/7 bruk. Easy tune trycker lätt upp spänningen onödigt högt. Tycker nog att du bör köra direkt i BIOS för bättre kontroll. Har samma överklockning som du men jag ligger aldrig över 72-73 grader på varmaste kärnan efter 8-10 timmar av Prime95. Har iof Noctua SE1366 med 2 fläktar i push-pull men flera tester ger att det bara bör skilja 2-3 grader mot "vanliga" U12P. Du kan också prova att disabla Hyper threading i BIOS, Hyperthreading ger dig 8 virtuella kärnor i st f 4 "riktiga" utterst få program och knappast några spel har stöd för hyperthreading. Att disabla hyperhtreading brukar ge ganska kraftigt resultat på temperaturen. Rekommenderar också att du kör CoreTemp (http://www.alcpu.com/CoreTemp/) istället för att lita på Easy tune.
Har också kopierat detta från något forum och kör samma settings på mitt Gigabytekort GA-EX58-UD3R, jag kör dock BCLK 170 med Turbo mode enabled. Det heter inte riktigt samma hos Gigabyte men intelligenta gissningar leder dig rätt:
Ai overclock Tuner: Manual <--- Leave that
CPU Ratio Setting: Auto <-- Leave that
Intel Speed Step: Disabled <-- Leave that
BCLK Frequency: 180 <-- Leave that
PCIE: 100 <-- Leave that
DRAM Freq: DDR-1443Mzh (Can I tweak this because I have DDR3 1600?) <-- You can set this higher, but it will put added stress on the chip
UCLK Freq: Auto <-- Set this to 2x+1 of your DRAM freq
QPI Link Data Rate: Auto <-- Set to the lowest possible setting
************************************
CPU Voltage: 1.35 <-- Good starting point
CPU PLL Voltage: 1.82 <-- Leave that
QPI/DRAM Core Voltage: 1.375 <-- Leave that
IOH: Auto <-- Leave that
IOH PCIE Voltage: Auto <-- Leave that
ICH Voltage: Auto <-- Leave that
ICH PCIE Voltage: Auto <-- Leave that
DRAM Bus Voltage: Auto <-- Set to at least 1.6v
-> Skipping all the DRAM Ref Voltages (They are all set to auto)
Load-Line Calibration: Auto <-- Set Enabled
CPU Differential Amplitude: Auto <-- Leave that
CPU Clock Skew: Auto <-- Leave that
IOH Clock Skew: Auto <-- Leave that
PCIE Spread Spectrum: Auto <-- Set Disabled
If you notice above, I have commented on your BIOS settings. Here's a few tips to explain my reasoning:
1. You can adjust your DRAM Freq if you are running memory if its rated higher than you are currently running. Remember though that higher memory speeds put added stress on the IMC and can lead to instability. You should be okay running your 1600 RAM at or slightly above 1600 until at least 4.2GHz.
2. Uclck Frequency: Your uclck must be at least 2x your RAM speed. I've found better results when running it at 2x+1, so if your RAM is running at 1600MHz...set this value to ~3400MHz.
3. Manually set your DRAM voltage. Most boards will overvolt this value when left to auto and this adds unnecessary heat. My P6T Dlx V2 uses 1.7v at 195 bclck which is a lot more than I need. I run my 1600MHz GSkill at 1.66 with tight timings but it will run 1600MHz at looser 9-9-9-24 timings. This value will need adjusting eventually but I recommend starting at 1.6v
4. Load Line Calibration: When pushing higher voltages I would recommend leaving this disabled but for your speeds I would set it to enabled. This will cause the vcore to slightly overvolt at idle and should all but guarantee that your vcore doesn't drop below the BIOS setting under load. When running over 1.45v I set this to disabled in order to prevent high overvolting from killing my chip.
