Can I Use a DDR3 1333 Kit with DDR3 1600 KIT?

[Dougofthenorth]

So I can use the HyperX DDR3 Tri-channel 1333 Hyperx RAM together
with the HyperX DDR3 Tri-channel 6GB HyperX RAM & get 9GB RAM ??

Using the 3 2GB Module Kit & the 3 1GB Module Kit together in the 6 MB slots??

Without any issues & have the 1333 run up to speed with the 1600 ?

CPU is @ 4.0 GHz now with the 1600 kit @ CL9

1333 is CL7 (7-7-7-20)

EDIT: I guess I should first ask is it even worth it to do (if it can be EASLY done)?

6 GB to 9GB - what advantages? I use this rig for gaming

If im not mistaken you can use but they all have to be on same frequency...

And 6gb is enough for gamer, 6-9 isnt big different, and somewhere on this forum i saw someone said more ram more harder to overclock.

In games, you won't see a difference.

Also, if the 1333 kit can OC, then it'll work well with the 1600 kit. They need to run the same frequencies/timings. They can be rated differently, but they must run at the same speeds.

It is not worth doing, and more RAM = more stress on the IMC.

The system will just run it all at the lower speed wont it.

You can indeed mix them but you'll have to run the faster RAM at a speed that will run on the lower RAM.

Unless you're doing workstation stuff though, I highly doubt you'll need 9GB.

Tx guys I will stick with just the 6GB kit

Is the CL 9 (9-9-9-27) as good as 7-7-7-20 ?? (will I see realistic a difference for gaming?

For some reason the 1600 kit won't accpet the CL7or CL8 timings - maybe because CPU is
at 4.0 GHz

As long as the 1333Mhz and the 1600MHz are in the same channel respectably, yes. You will notice no difference at lower frequencies. Lower the 1600MHz ram like mentioned.
