New ddr4 memory problem
New ddr4 memory problem
I recently purchased a 16 GB Corsair Vengeance LX 2666MHz DDR4 (2x8GB) to upgrade from my standard Lenovo 8GB DDR4 2666MHz RAM. The previous RAM was running at 2666MHz, but after installing the new sticks, it defaulted to 2133MHz and I can't adjust the setting in the BIOS. I'm not sure why this happened since the old RAM was also at 2666MHz. Can you help me understand what's going on?
