Question Am I able to mix CL16 1.25V with CL22 1.35V ?

[bloodyroxas]

Currently I have 2 Kingston HyperX Fury 16GB DDR4-3200Mhz stock RAM in my Aurora R12.
I am planning to slot 2 more Kingston HyperX Fury DDR4-3200Mhz 16GB RAM which I bought.
I notice that the stock using XMP profile only max at 1.25V for 3200Mhz, the one I bought have XMP profile of 1.35V for 3200Mhz.
Details of my current systems below
CPU: 11th Gen Intel Core i9-11900KF @ 3.50GHz

This is the Specsheet

The question is will it work if I were to slot the new ram in with the old ram?

It's a gamble if it will work. You can only tell if two different sets of RAM will work together by testing them together. Even identically branded RAM kits are not guaranteed to work together.

My guess is no.

What is plan "B" if your new sticks can't be made to work?
3200 speed ram with a 1.35 spec is going to run slower at 1.2v.
That lowers the performance of all your ram to less than th3200 speed.
Running 4 sticks is more difficult than two.
To make it work at all, you need to have a motherboard bios that lets you adjust ram specs, particularly voltage.

Do you really need 64gb?
Few apps can take advantage or more than 16gb.
If you really need 64gb, buy a single 64gb replacement kit.

Run em both at 1.35 and see what happens. If it doesn't work on the first test switch banks and try again. Certainly not ideal but it's worth a shot.
