Step 5: Find Your CB( Cold Bug) and CBB( Cold Boot Bug) Temperatures
If you’ re not an experienced extreme overclocker we suggest you to spend the time to find the CB and CBB of your CPU. Once you find them you will be able to eliminate CB and CBB off of a list of issues that may be hindering your overclock. Cold Bug is the lowest temperature your CPU can operate at. Cold Boot Bug is the lowest temperature your CPU be at and still boot. From our experience with the 7th gen CPUs, we’ ve seen that CB and CBB are very similar to the previous 6th gen CPUs. CBB is mostly CPU specific and it is approximately around-130C. Some CPUs may be able to boot at-120C and some at-135C. CB on all the CPUs we’ ve tried are the same-you can go full pot(-190C).
Step 6: Adjust Frequencies + Some Tips
• CPU frequencies range from 6.4 to 6.9 and maybe even higher for HWBOT Prime. Good CPUs can do 6700 + with around 1.8V. Some CPUs stop scaling at around 1.8-1.85V but some can go up to 1.9 +.
• Some good news-from our observations we’ ve seen that average next-gen retail Intel CPUs can clock as high as engineering samples.
• Uncore uses CPU Vcore voltage. If you want to raise Uncore frequency you might want to raise CPU Vcore voltage. 6700 Mhz Uncore worked for us on SuperPi 32M.
• If you’ re hitting lower frequencies( i. e 6 Ghz) make sure your CPU mounting is good.
• Compared to a Gaming 7 motherboard the same CPU could only clock up to 6.2 Ghz, when on Gaming SOC due to its extra voltage settings it was able to do 6.7 Ghz. We found no difference between the motherboards when doing standard overclocking on air or water.
Step 7: Troubleshooting
Potential issue: previously stable frequencies are now unstable
Make sure you have a stable mount when you are overclocking. You will find that once you start to push high frequencies and volts that your paste may not work correctly and your CPU can become unstable at previously stable frequencies. The best way to OC is to use a staggered approach where you start with a 5, 5.5, 6 and 6.5 Ghz profiles with specific volts and temp ranges. If you crash at any stage, you probably " lost your mount ". Essentially your paste snapped and is not conducting heat properly between the CPU HS and CPU pot. One way you can detect this is with a delta probe( keep one temperature probe on HS and second on CPU pot).
