Hi all,
I have been told that if if placed some 1600mhz memory in my system it would still read as 1333mhz, i have found some boards that say they take 1600mhz but dont state anything about overclocking the ram but it does state 1800mhz and 2000mhz will need to be overclocked to get these speeds.

So if i put some 1600mhz memory in my system and i didnt want to overclock anything it would run as 1333mhz, so i could save money and get 1333mhz speed rather than 1600mhz and it run at the same speed.

Any help would be great.

Thanks

The thing is, putting your memory to 1600 mhz wouldn't be oc'ing it, it would just be a matter of changing settings. Also, the 1333mhz memory has the ability to be oc'ed into 1600 mhz.

I am looking at getting the Corsair Dominator memory, there is a 25 to 35 pound difference, it will be running with a phenom ii 955, asus m4a89gtd pro.

in your opinion what would you get the 1333mhz or 1600mhz both 1.65v.

Is it as simple as just changing the speed to 1600mhz in the bios.

Do you know what the performance difference speed is between the two.

Thanks

If you are aquainted with overclocking, then get the 1333mhz, if you want to get aquainted go with the 1600mhz. Also if you want to just set it to the standard go forthe 1600mhz. However, there has been proof that faster ram is not always better, but generally the 1600 mhz models are made bettter, with better timings also. Timings are more important than mhz speed.

If you have tight timings and its set to 1333mhz, it theoretically would be faster than 1600mhz memory with looser timings.

just looked at some charts and there is minimal difference in performance between 1333mhz and the 1600mhz stock into you overclock them but i am not overclocking, do you think it is best to stick with the 1333mhz and put the money somewhere else on the build.

Yes, put the money towards something else, go for the 1333mhz

ok these are the two i am looking at
1600mhz cas 7-8-7-20

1333mhz cas 9-9-9-24

Even if i get the 1600mhz i may o/c in the future.

As i said before i will be running phenom ii 955 be and looking to run dual 5870 cards on 1920x1080 res.

ok i will stick to the 1333mhz and upgrade the power supply. thanks for your help

But the 1600mhz, like i said earlier, it has tighter timings, which is where the performance difference is. The tighter the better.

i know, what would you get in your opinion with the build above

Well if you have a tight budget, go for the 1333mhz, for two reasons, you can set the timings yourself, second you can learn how to properly set timings and how to overclock them respectively.
In my view, its a win win!

ok thanks for all your help, you have been a great help. always happy to learn.
