Recently, a lot of Windows users encountered the “Fatal Error: rounding” error when they are trying to perform a stress test using Prime95. Mostly, this error is associated with an overclocked CPU. The error usually caused by an inadequate CPU voltage, insufficient power supplied by PSU, outstanding internal component temperature or several other reasons.
Fixes for Prime95“Fatal Error: Rounding”
However, the said error is not a serious one, and we have listed below some reliable solutions that have helped the affected users get rid of this error. If you have experienced a similar situation, then you have come to the right place. Some of the effective fixes we have listed here will help you to solve this issue. Let’s learn more about this.
Fix 1: Clear the CMOS battery:
As per some suffered users, this issue may be due to temporarily saved data being perpetuated by the CMOS battery used by your motherboard. Data previously saved in connection with DOCP is likely to affect your CPU’s behavior under current stressful situations. In this case, it is advisable to open your system case and clear the CMOS battery. For doing so, follow the steps given below.
- Firstly, turn off your system entirely and unplug the system from the power source.
- And using a Static Wrist Band, remove the side cover of your computer. (to eliminate the risk of damaging your PC’s internals, you should use a static wrist band).
- Once you opened the side cover of the PC, locate and identify the CMOS battery. Then remove the battery from the slot using your fingernail or a non-conductive screwdriver.
- Next, wait for one or two minutes to allow the power capacitors to drain entirely. Then reinstate the CMOS battery and put the side cover back on.
- Finally, Re-plug your computer into a power source and boot normally before starting another stress test with Prime95.
- After cleaning the CMOS battery, you would be got rid of the “Fatal Error: Rounding” issue.
Fix 2: Raise the CPU voltage:
At times, slightly raising the voltage of the CPU helped few users to resolve the “Fatal Error: rounding” error. As we discussed above, mostly, this error occurs due to insufficient voltage supplied to the CPU. Prime95 indicating that the CPU is not stable enough to do stressful tasks that need extra processing power.
