Another inquiry about RAM
You received a Lenovo Legion Tower 7i with an Intel i9 14900KF and a 4070Ti Super. It came with 2x16GB or 32GB of RAM at 4000MHz, which wasn’t ideal. You decided to upgrade it with Corsair Dominator Titanium RAM offering 64GB at 6600MHz and 1.4V. The timings are listed as 32-39-39-76, but the manual doesn’t specify exactly what to do. Your main concern is configuring this new RAM in your BIOS—XMP isn’t working, and the motherboard doesn’t support those settings. So you’re stuck with auto mode. It boots fine but only uses the same speeds as the original RAM. The board supports up to 5600MHz, so you can increase it if needed. You’re wondering whether to raise the voltage from the stock 1V to 1.4V in your BIOS or stick with the default. The RAM specifies 1.4V, but the board runs at 1V. Should you change the voltage for better performance? It depends on stability and compatibility. Raising it might help, but could also cause issues. In short, leave it at 1V unless you’re certain it’s optimal. If you need more guidance, the specs are here: https://www.lenovo.com/us/en/p/desktops/...90v6000kus
The problem lies with this being a Lenovo build. Such prebuilt units usually lack memory overclocking support, meaning you're limited to the JEDEC speed your hardware supports. If you have time before returning, send it back and opt for a 2x32GB 5600 CL46 model instead—it will work just as well. In practice, I’d suggest doing that regardless, since Dominator kits are overpriced and you can’t exceed the 5600 CL46 speed.
It seems to be taking its time, but it's actually just normal. Getting that huge amount of RAM quickly wasn't a good move, particularly for a Lenovo pre-built. It's best to return the RAM and stick with what came with the device.
