Best option for Memory for desktop. 24gb @ 1700mhz or 16gb @ 2400 mhz

[crazyjoker1201]

ok so my old memory is 2x 4gb sticks @ 1600ghz and my new memory is 2 x 8gb @ 2400 ghz.

i was wondering if it would be better to take the old memory out so i can run my new memory at a higer frequency?
or to leave it all in there n run it at like 1600ghz with 24gb.

what would be a better choice?
I would get 16gb @ 2400 ghz or 24gbz @1700ghz

from what I've read, over 1600MHz memory doesn't make much of a difference to anything, so maybe use 24GB. Do you use applications that demand over 8GB of memory?

Try the 8GB sticks by themselves initially - then once you know they are good can always try adding the older - if any problems, give me a shout
