DDR3 Speeds

[UrKo]

My current ram is 8gb 2133mhz Geil black dragon

I am looking to buy 16gb of Hyper X 1866mhz

question 1 will i see any noticeable difference in the slight reduction in speed? i am guessing not

question 2 can i mix the 1866mhz hyper x and the 2133mhz geil? i am guessing i can but would have to reduce the geil to match the 1866mhz speed of the hyper x.

Its been a while since i bought parts.

1) You'd see more performance increase by the increase in available RAM, than any decrease in actual ram speeds.

2) correct

Also, double check the timings, eg 9-9-9-24

Can tighten the timings with a lowered speed

just sell the old ones dude, mis matching ram will cost you performance from an increase in latency. how noticeable it would be is really down to a per use basis, but it is there

the 16gb set will probably run 2133, if not higher

You'd only ever really notice it in benchmark scores though, and the performance boost you'd get would outweigh the latency increase. Especially when you're only talking a couple of hundred mhz..

how often will the 16gb limit be the issue?

i know i can fill it (and 32gb) with ease but it is about the usage of the system. i would guess 90% : gaming 10% 1 handed browsing and here you want it to be as instant as possible to get the best fps (or page closing ability)

Lol yeah gaming primarily.

I will be doing some photo editing as well as i get more profficient with my SLR.

Other than that the pc is constantly folding. No one handed browsing

folding will get nice gains from having your ram as tight as possible. photo editing might like the extra ram.
