HELP TC-895-EB11 - New 2666MHz RAM running @2133MHz

Hello Community

I recently upgraded the 12GB RAM on my PC to 32GB Corsair Vengeance LPX CMK32GX4M2A2666C16
The stock RAM was:
Kingston 8gb 1rx8 Pc4-2666v-ua2-11 Ddr4 Desktop Memory 9995702
Kingston 4gb 1rx4 Pc4-2666v-uc0-11 Ddr4 Desktop Memory 9995665

After installation my RAM is only running at 2133MHz as shown in Windows 10 task manager.



I see that Acer has a BIOS update that may allow me to enable XMP here but there are no release notes so I am hesitant to try.

Anybody have this BIOS version?

The Comet Lake chipset supports 2666MHz.

Any ideas to get me to 2666MHz?
Am I stuck at 2133MHz with this motherboard?

Thanks in advance!

Hi,
These modules have automatic overclocking enabled, their speed is 2133MHz but whenever it's needed they can overclock to 2666MHz, if you have chosen normal RAM modules without XMP profile, you would have the system working at 2666MHz.
