Looking for assistance with boosting the 5820k on an Asrock Tiachi board?
Hello, I'm a total newbie in overclocking processors and was hoping for some guidance. I've already managed to push my CPU to 4ghz, but after that it wouldn't even start up, not even the BIOS. I cleared the CMOS and everything seems fine now. I'm interested in trying to get it to run between 4.0 and 4.2 GHz. Do you know anyone who's familiar with ASRock BIOS who can share some tips or examples of how to do this?
Ensure you have the most recent BIOS installed for the board. There are currently two available versions, with 1.4 being the latest.
You should not adjust your cache settings at all.
Keep the spread spectrum unchanged from its default values.
In the FIVR Configuration, switch the voltage mode to override fixed voltage and set it to 1.18. This should suffice for 4.0, and you might be able to reduce it further if needed.
Exit the FIVR Configuration and navigate to the "Voltage Configuration" menu. Adjust your input voltage to 1.8. If you plan to increase clock or core voltage later, this setting may need updating as well.
I reviewed the adjustments made prior to encountering the problems.
the exact adjustments you made before encountering problems are as follows: modified the CPU ratio to 40, cpu cache ratio to 35, adjusted the vcore voltage to All Core at 1.2v, turned off spread spectrum, and left all other settings in auto mode. The 1.2v was the minimum voltage available, and I wasn't able to set a custom voltage unless something went wrong.

You should not adjust your cache settings at any time.
Keep the spread spectrum unchanged unless necessary.
In the FIVR Configuration, switch the voltage mode to override fixed voltage and set it to 1.18. This should suffice for 4.0; you might be able to reduce it further if needed.
Exit the FIVR Configuration and navigate to the "Voltage Configuration" section. Adjust your input voltage to 1.8. If you plan to increase clock or core voltage later, this adjustment may be necessary, but it should work for a moderate upgrade to 4.0 or 4.1.
Also, consider setting CPU Load-Line Calibration to high to avoid vDroop under load, which can lead to blue screens.
Download and install Prime95, then perform the Blend Test. Monitor all 12 threads in Task Manager or observe the self-tests in Prime95. Stability is confirmed if tests pass consistently without any failures (or if your threads remain at 100% capacity).
If any self-tests fail in Prime95, increase the input voltage from 1.8 to 1.82 before modifying vCore.
Should you encounter a blue screen, it usually indicates under-voltage on the vCore. Verify that the load line calibration is set to the maximum level; if not, raise vCore to 1.19 and retest.
Regarding cooling, based on typical observations during Prime95 tests, I prefer not to see any core temperature exceed 80°C for more than a few seconds—meaning they might briefly reach around 82°C for short periods. You can use "coretemp" software to track core temperatures throughout your tests.

The cooler should work well for a mild overclock like 4.0. Keep an eye on core temperatures. The main adjustments are:
- Adjust all cores to 40
- Fix the core voltage (under FIVR) and set it to 1.18
- Change input voltage to 1.8
These should cover it for 4.0. If you have RAM faster than DDR4 2133, use the XMP profile under memory settings; the board will try to use it automatically, though results may vary. For RAM at 2666 or above, be cautious as XMP can also set BLCK to 120 instead of 100, altering your CPU clock requirements.
The cooler looks suitable for a mild overclock of around 4.0. Keep an eye on the core temperatures. You'll mainly need to adjust these settings:
- Make all cores run at 40
- Fix the core voltage (under FIVR) to a fixed value and set it to 1.18
- Set your input voltage to 1.8
These should cover the requirements for 4.0.
If you have RAM faster than DDR4 2133, adjust the XMP profile under the memory page. The board will try to use it automatically, but it might not be perfect. For RAM at 2666 or above, be cautious because setting the XMP profile can also change the BLCK value to 120 instead of 100, which affects your CPU clock settings.
Thanks for trying the recommendations. I ran Prime95 for 30 minutes with no crashes or blue screens—temperatures stayed below 80, only briefly hit 82. Should be safe to proceed?
It should be fine if you want to leave things as they are. I’d consider resetting the core voltage to auto just to check stability. At 4.0 it might work well, possibly giving cooler temperatures which is beneficial. Alternatively, scale back to 1.17 and test again; if stable, go down to 1.16.
Your temperatures are acceptable since no applications will ever put significant load on your CPU, far below what Prime95 can handle. You should probably never exceed 60 seconds under typical use.
