The first thing I check in every new PC's BIOS is a setting most people leave switched off by accident
The author advises checking the BIOS memory profile setting on new PCs to ensure RAM runs at its advertised speed. Many systems default to the conservative JEDEC profile, which can significantly reduce performance compared to the XMP or EXPO profiles. Enabling the appropriate profile in the BIOS restores the intended speed and improves overall system performance.
- ▪RAM often boots at JEDEC default speeds unless the XMP (Intel) or EXPO (AMD) profile is enabled in the BIOS.
- ▪The author uses Task Manager's memory speed reading as a quick diagnostic to spot this issue.
- ▪Enabling XMP/EXPO can raise DDR4 and DDR5 modules from 2133 MT/s or 4800 MT/s to their rated 3200 MT/s or 6000 MT/s respectively.
- ▪Performance loss from running at JEDEC defaults can exceed 40% in benchmark tests.
