Do different sizes of RAM effect the speed of the memory's performance?

[eviLocK]

Consider a case, where there are two set s of RAMs with all things equal such as, brand, model, CL and MHz values, all except with the sticks' size, one is in 8G's and one is in 16G's.

If they were in Dual, Triple and Quad mode, is there any speed performance differences between the 8G set and the 16G set, assuming they are used with the same number of ram sticks in each mode (with 16G set resulting in more memory size than the 8G set)?

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.

Now assuming that you can get the two sticks to work.
There is no triple or quad channel mode unless you are looking at X99 type motherboards.
The balanced 8gb on each channel will run in dual channel mode. The odd 8gb will operate in single channel mode.

As to speed, higher speed is negated by higher cas numbers.
That makes ram speed largely irrelevant to actual app performance or FPS.


And... if your os is windows 7 home, you will need an upgrade to address >16gb.

Sorry that I did not make myself clear. I am a poor writer. I did not mean 8G and 16 G sets are used on the same board at the same time, but the two scenarios with one with all 8G sticks and the other with all 16G sticks, granted all things equal with same components within the sets, etc.

Would there be any speed performance differences?
