Hi all,

Yet another question that you've probably heard before.
I have a 1x4GB Corsair XMS3 stick in my desktop currently, but I wanted to add some more.
I bought some more (2X4GB Corsair XMS3), and the speeds were faster (which I know that is usually OK to mix).
HOWEVER, the new ram runs at the timings of 11-11-11-30, whereas the old runs at 9-9-9-24.
The system I run is a Dell Optiplex 780 (SFF) with the standard mobo.

Now, should I...
A) Mix them, boot into the bios, and change the settings, or
B) Not use the old 9-9-9-24 and use the new ones on its own.

Thanks for ye olde helpe.

If you mix them together, you are better to set the settings to auto. One thing you need to make sure the RAM is 1600MHz 11-11-11-30 or 1866MHz 11-11-11-30, if it is the 1600Mhz, then they will run in the lower speed/timing at 1600MHz 11-11-11-30. If RMA is 1866MHz, then they will run in 1600MHz 9-9-9-24 after you mix them.

Also when you mix the RAM, the RAM will run in the single channel mode because you have 3x4GB, even though they have a small difference between them.

And there is no difference between 8GB and 12GB. If you don't use the PC for heavy photo/video editting then just get other 4GB RAM.,...

Check your BIOS first - you have no controls to change anything significant, this is cheap Dell after all.
