Error encountered following installation of new hardware.
Error encountered following installation of new hardware.
Hello, my nephew made some changes to his PC. He kept the same CPU and SSD, but everything else was new. Since he plays Fortnite, he tried updating the game after installing the drivers. It crashed at 17% and then worked again. When he tried to update Fortnite once more, it still failed at that point, showing "IRQL_NOT_LESS_OR_EQUAL." He asked me to check the situation and after some testing, I realized the problem might be related to the RAM configuration. He has a Gigabyte B550M DS3H with 128GB of DDR4, which supports 32GB of Corsair DDR4 3200. He runs games fine and can update without issues when both sticks are used. The issue appears only when one stick is removed, possibly because the system tries to access something during that moment. The error seems tied to hardware compatibility or driver settings rather than a single program problem.
The issue you're encountering, "IRQL_NOT_LESS_OR_EQUAL," often stems from insufficient RAM voltage. You might need to slightly increase the voltage a bit to resolve it. Remember, adjust gradually—not drastically. If low voltage is the root cause, raise it by roughly 0.2 volts, such as from 1.25v to 1.27v, or follow the next available step up in increments. The BIOS usually indicates the correct voltage in its settings. Once you stabilize the change, the error should decrease. Aim for around 1.30v for most systems, but 1.40v is generally safe before reaching limits. The DDR4 standard is about 1.35v. If your system uses auto settings, switch to manual and incrementally increase until the problem stops. Also, verify that your RAM matches the board's specifications—some boards only recognize certain models. Occasionally, a faulty stick can trigger this error, so consider replacing it if possible. Check the manufacturer's QVL list for your exact model and version to confirm compatibility. If the match is correct, the issue may be with the board itself.
I agree with your perspective, though I realize the issue often stems from insufficient RAM voltage. It’s simpler to resolve than other complications, so it’s worth checking first before exploring software fixes. This also varies depending on the task you’re performing. I’ve encountered this problem repeatedly during bench sessions—it’s quite frequent. For my experience, adjusting the RAM voltage was a quick and effective solution. When I refer to a bench session, I’m not talking about typical setups, but rather more specialized scenarios like DICE or Ln2 configurations. Machine usage definitely plays a role in its occurrence, even for standard desktop issues, where a small change in RAM voltage resolved the matter swiftly. That’s why I recommended it.
