Sandy Bridge OC Thread V2

Our old V1 Thread has exceeded 2500 posts so this is the V2 thread of Intel LGA1155 aka Sandy Bridge (SB) overclocking thread.
Please share your benchmark, stability, guides etc...

Latest BIOS:

BCLK
measured in MHz
Base Clock Increasing your base clock increases your CPU core clocks, memory speed, QPI frequency, and North Bridge Frequency
-Similar to the older FSB “Front Side Bus”
BCLK x CPU ratio = CPU frequency
Adjust the BCLK frequency to overclock the CPU speed!

Multiplier
-Multiplier is a ratio that determines the clock speed for the CPU based on the multiplication of the BCLK. For example, your CPU multiplier determines what your CPU core clock speed is using this formula: Base clock * multiplier
There are also multipliers for Memory frequency, QPI speed, and North Bridge (UCLK) frequency.

PCIE
measured in MHz
Periferal Connect Interface Express
-Video Graphics communication link
when overclocking, increasing the PCI-E clock can help with stability when above 200MHz BCLK

CPU Voltage
AKA -VCore this is your processor core voltage. Increasing this will supply your CPU cores the power they need to operate at higher frequencies.
Central Processing Unit
-Processor core voltage
DO NOT EXCEED 1.55v

IMC Voltage
"VTT" or "QPI" Increasing this will supply the power needed for the IMC (North Bridge) to operate at higher frequencies.
- L3 shared cache
- memory controller
- processor I/O power rail
Since memory controller frequency is dependent on BCLK, the higher the BCLK, the higher the IMC voltage required. DO NOT Exceed 1.45v

DRAM Voltage
DDR3 Random Access Memory
-Memory Voltage
Since DRAM speed is linked to the BCLK the higher the BCLK the higher the DRAM Voltage is needed

CPU PLL Voltage
PLL: Phase Locked Loop voltage
- Processor/IMC(Integrated Memory Controller)/other internal clock cycles
- Clock multiplying of processor is provided by an internal Phase Locked Loop
Does not have a significant effect on CPU Speed, -DO NOT Exceed 1.90v

PCH Voltage
Platform Controller Hub
- main I/O interface for CPU
- display connectivity
- Integrated Audio
- power management features
- Storage features
The higher the CPU frequency, the harder the I/O (input and output) has to work so there is higher power consumption and more heat is generated, raising the CPU temperature. The PCH voltage needs to be increased in order to stabilize I/O signaling. DO NOT EXCEED 1.25v

Open RealTemp
Execute Task Manager > Performance tab
Launch Prime95 27.7
Choose custom, min FFT 128k, mem to use (see task manager for available mem)
Start stressing
Monitor the max temp make sure it doesn't exceed 105C (TJmax) - speed will go down (throttled) if TJmax is hit to protect the CPU from overheating
Stress it for 3 hours +
Don't stop priming & open CPU-Z
Take screenshot including Prime95 + CPU-Z + Task Manager + RealTemp

some tips for sandy bridge user..
U all can test the system stability in shorter time with prime95..
Just select custom and test with
1344fft 1344fft 1minute 80-90% available ram for 15mins
If can passed the test u can test with 1792fft 1792fft 1minute 80-90% available ram for 15mins too..

If passed 2 tests on certain vcore..then your system should stable for 12hours prime95 blend test.

the 1344 and 1792 fft is the extremely hard and best test for sb`stability

Normally,if your system is unstable..one of the workers in prime95 will stop/BSOD will happen within 10mins of both test

BSOD codes for overclocking
QUOTE
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT... have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

question here, do u guys keep ur speed at OCed speed for 24/7 usage?
the electricity bill will very expensive doh.gif

No point to run stress test if not for 24/7 so I kept my 2600K @ 5GHz all the time.
Main purpose is to make games gain more FPS and other CPU intensive stuffs.

i see, but if i keep it at stock speed, vcore around 1.1x
but if i put at 4.5ghz, the vcore will fixed at 1.37v or depend on my usage?
if 3.3ghz vs 4.5ghz at idle, the electricity comsumption will be the same?

3.3 vs 4.5, there would be a difference in terms of power consumption even during idle.

sigh, then maybe need to go back to stock speed, electricity bill too high doh.gif
after i update my bios everything back to default, and i realized that the vcore for stock speed is lower already.
since new bios provide more stability, do i need to lower the vcore and run stress test again for the OCed speed?

The new bios might need higher vCore also.
So no such thing when you see stock vCore is lower your OC vcore will get lower that's not true. But best if you could retest.

hi i got a question.
i just reapply tim using mx4
using 212 + push fan only
without oc
my i5 2500k temp is already reaching
58 62 62 56

is it because i apply the tim wrongly?

currently i only tighten my ram and my ram volt is 1.355

notworthy.gif thank you
i will post the oc result later brows.gif

last time i oc my proc to 4.3
with 1.285 vcore
the max temp is at 64-68

so any other thoughts?

Looks good bro. As long as you keep it below 98C would be fine. smile.gif best is below 80C.

Hello sifus, still a beginner at OC, I have some question regarding my OC i5 2500k @ 4.5Ghz.

Using MSI P67A-GD65, I set 1.3V Vcore at the bios, and the bottom shows that it is running at 1.28v. However once boot into the Windows, CPUZ show me Core VID of 1.376v, but AIDA CPUID do show the same 1.28v.

During prime95, CPUz shows 1.381v and AIDA shows 1.271v.

Which value show i trust?

CPU-Z or CoreTemp? CPU-Z will show vCore, not VID.
VID is different from vCore. VID, is essentially the amount of power required to get it going. Vcore is the voltage that the CPU is running at.
What's your vdroop control set in BIOS? FYI, vCore set in BIOS will not be the same as those readings on CPU-Z & AIDA due to vdroop/vdrop. You might wanna google for more infos on that.
Some screenshots might help on your problem.

Be sure in cpuz.ini file Sensor=1.......Core Voltage.
Sensor=0.........Core VID.

To be sure run this portable CPU-Z :

My Vdroop in bios is high. I will be using AIDA CPUz as my references now since I changed the cpuz.ini to display VID.

Attached Image

Been increase my Core voltage in bios from 1.3 to 1.325 currently. Still finding a stable voltage for my 4.5Ghz.
Do I have to worry about VID readings too in my OC ? Or I can just ignore it and only pay attention to the Vcore and temperature?

Is my temperature doing fine ? I do suspect that my heatsink is not installed so probably and thus result a high temperature.

I think i know the problem. Since my CPUz cannot be run together with AIDA, I did changed the sensor=0 in cpuz.ini. And thats why i mixed up with the default Core voltage reading.

I'd pay attention on the vCore, since it's used in the BIOS.
VID is useful for chip binning. smile.gif
Your temps look fine.
