[SOLVED] 12 gb 2666 or 8 gb 3200

[AspectSaber]

Hello so I recently got a new pc, and I want to put more ram. Meanwhile I save up money to buy a 16 gig kit, is it okay if I put my old pc ram into my new one? My current one has dual channel ram 8 gb running at 3200 mhz, but I have another stick of ram that is identical to the current one but it just has a lower speed of 8 gb. My new pc only has 2 ram slots, so would I be better of putting 12 gb of ram running at 2666 mhz or 8 gb 3200 mhz? For the 12 gigabyte one the configuration will be 1x8 2666 and 1x4 3200. Any help is appreciated and I just want the answer to my question.

doesn't hurt to try.

Will there be any performance sacrifice switching from 3200 to 2666?

if you are running out of ram. don't matter if it will run slower
