[SOLVED] Getting 1866MHz RAM for 1600MHz Motherboard

[Yosef Marcera]

I currently have 2x4GB DDR3 1600MHz CL11 HyperX Fury sticks on a Gigabyte GA-H77-DS3H motherboard, the motherboard only supports RAM speeds up to 1600MHz. I found a good second hand deal on two more 4GB HyperX Fury sticks that are rated at 1866MHz, I just wanted to know if installing these faster sticks would cause for any instability or performance drops. I am aware that since my first two sticks and motherboard run at 1600MHz, the 1866MHz RAM will slow down to match, but will it affect performance? Here is a screenshot of the timings of each RAM:

If they do work together, faster RAM will slow down to speed of slower one, If you get both sets to work each in dual channel mode you should have no problems or performance issues.

Nothing will be slowed down. Just those RAMs with faster MHz will be downclocked to the slower MHz RAM. That's it.

Just ? Isn't downclocking slowing down ?

He won't be downclocked from his current setup, because his current RAM runs with 1600MHz and his moterhboard also supports only 1600MHz, so in practice he will have same speed with just more capacity of RAM.

The old RAM will slow down to speed of slower(new) RAM.

Nothing will slow down because his current motherboard doesn't even allow higher mhz. And secondly the new RAM he's aiming has higher speed than his current RAM. Can't believe that I have to explain such simple things.
