Best BIOS Setting for 4.8GHz

[El_Capitan]

Here are my results:

 

i7 2600k | GIGABYTE GA-Z68X-UD7-B3 | 4.8GHz (48 x 100Mhz)

 

BIOS Settings (GIGABYTE GA-Z68X-UD7-B3):

Internal CPU PLL Overvoltage = Enabled

Real-Time Ratio Changes in OS = Disabled

Intel® Turbo Boost Tech. = Disabled

CPU Enhanced Halt (C1E) = Disabled

C3/C6 State Support = Disabled

CPU Thermal Monitor = Disabled

CPU EIST Function = Disabled

Multi Steps Load Line = Level 6

VCore = 1.455V (AIDA64 CPUID reported 1.440V (Full Load 100%) - 1.476V (IDLE))

 

Prime95 (Blend) 1 hour pass no errors:

Max Temps (HW Monitor Pro / RealTemp)

CPU = 68C (HW Monitor)

Core1 = 70C (RealTemp)

Core2 = 79C (RealTemp)

Core3 = 79C (RealTemp)

Core4 = 76C (RealTemp)

Max CPU Power (HW Monitor) = 107.66W

 

LinX 25000 Problem size, 20 Runs, Pass no errors (1 Hour Aprox.)

Max Temps (HW Monitor Pro / RealTemp)

CPU = 68C (HW Monitor)

Core1 = 70C (RealTemp)

Core2 = 80C (RealTemp)

Core3 = 79C (RealTemp)

Core4 = 77C (RealTemp)

Max CPU Power (HW Monitor) = 107.80W

is these results good for 24/7 or I need to change something?

Is this with the latest BIOS? Higher voltage at idle than load seems odd, but if it's stable...

 

Those seem like high voltages for 4.8GHz. Drop voltage down more and see if you're stable?

 

TCASE = 72.6°C

TJMAX = ~95-98°C

 

Your temps are okay. I try not to get over 72.6C, but 80C isn't bad.

The BIOS is F8, droping voltage for how much (1 noch 0.005V or more)? Do I need to run tests after each change of vcore?The voltages AIDA64 reported was 1.440v Full Load and 1.464 - 1.476v IDLE.

 

TCASE (TDP) = MAX CPU TEMPS

TJMAX = MAX CORE TEMPS

 

am I right?

Re-stress test with any changes.

Are you leaving hyperthreading on?

I noticed I have 10c higher temps when HT is on and have to use a higher Vcore.

My board is a MSI P67A-GD65/I7 2600K chip. I was using an old Corsair Nautilus 500 water cooler with updated Danger Den Radiator but my temps where still high. Example: 4.6G/1.330 Vcore Prime95 small 73-81-83-80..........4.7G/1.360 Vcore Prime95 small 79-86-86-84...............4.8G/1.385 Vcore Prime95 ???? I understand running over 70c for extended Prime95 sessions is not good for the Proc.

 

Note: I had a chip I'm taking back that took higher Vcore to be stable as in 4.6 took 1.410 Vcore 73-80-80-76.......4.7 took 1.440 Vcore 73-80-80-77.......4.8 took 1.475 Vcore 75-82-83-79 All temps at Prime95 small and H20 920 water cooler.

 

Waiting for H100 twin 120mm radiator from NewEgg to come in tommorow.

 

What's funning on the watercooling is water temp was aprox 32c and block temp at 34c as measured with a Centec Laser Thermometer, ambient temps around 25c-27c. Changed out 2 different water blocks on the Natilus 500 with no change.

Wow..........this thread died pretty quick!

 

Anyhow, I'm at 4.8 with the H100 water cooler. On the HAF 912 its not a drop in, you have to move th radiator to the left side and rear of center under the twin 120's grill on top. Whoever designed the case wasn't thinking about the radiator being longer than the fans with the end tanks. Also brought the hoses down on the front of the tanks to give clearance to the rear fan. Turns out I needed 1/4 inch forward to clear. I'll mount the fan on the outside rear. Seems to be the best cheap watercooler so far at $100. Prime 95 blend is running 66-72-73-69 average with highs of 70-77-79-75 (ambi 23.5c) on high fan which is pretty noisy. Sounds like a loud microwave. I understand the Cougar fans have a 17db at 70cfm ratting, may pickup a couple and quite this thing down. I'm running 1.4vcore and 1.521 dram v's with corsair vengance 1600 mhz 16G. Will post pics as soon as I find the card reader. figure someone out there may be trying to set up a similar system while going for 4.8 and beyond.
