memory timings v memory speed

Hi I know this is a lazy post, however it has to be done

which would be better performance wise:

2400Mhz @ 9,11,11,31

or

2800Mhz @ 12,14,14,36

Intel or AMD?

Complicated one - depends a bit on what your doing - current Intel platforms seem to give the most balanced performance around 2133/2400 CAS9, with 1866 with good timings so close behind its a good budget buy point. Higher frequencies really only are worth it if your doing something that specifically takes advantage of pure frequency.

Intel,

Cheers, found this interesting article:

Will have a proper look at it tonight

I would go for memory speed and the 2800Mhz. The extra speed as at the cost of the latency but in all honesty you'll not notice anything between the two. Maybe a few extra single points in PC mark but nothing to write home about.

You have to benchmark both in the application you're interested in, simple as that.

(But usually higher MHz wins.)
