Combining memory chips.
Combining memory chips.
Hi. You have six Corsair Corsair Vengeance RGB Pro 8GB sticks with CL16-18-18-36, upgraded to an 8GB configuration using eight sticks for a 64GB quad channel setup. Your concern is whether you can combine another kit (v5.32) into your existing set of six, despite the different ICs from Samsung and Hynix.
If you already have the RAM, there's no harm in trying it. Worst case is that XMP fails to boot and you need to remove the sticks. Given that the memory controller on the 6850K has a first gen DDR4 controller, and the X99 was a first gen DDR4 board, I think there's a fair chance mixing RAM running above the rated DDR4-2400 will cause issues. But it also might work just fine.
Using various RAM chips can affect overclocking options but usually works fine, meeting JEDEC standards. They follow the DDR4 rule. In my previous setup I had a mix of Micron and SK Hynix DDR3 sticks—now I have four Micron modules and they operated at their designed rates without problems.
