is my ram configuration is ok?

Hello, i used to know a song that all sings, like: its best to use same Mhz, FSB rams, when u use more then one ram slot. And i noticed that my acer aspire 5738G haz: 2 memory cardsm its

1st slot:

According to CPU-Z my motherboard is Acer JV50

And my cpu is Intel Core 2 Duo T6600 and it says that bus speed is 199,5Mhz, and related is FSB is 798mhz.

what is a related fsb?

Is this a good 3GB ram build? i mean, first one seems is 667mhz, second one is 800mhz...

and why it says: DDR2-667 (333 MHz), what it means 333? it runs at half power or something?

 

What you have is fine. Running memory modules that are the same doesn't add anything of value to you.

 

More RAM > not running dual channel/kits. Just use it as is. Did you stress test your RAM to make sure both sticks are good?

 

Oh, what u mean by saying?

and yah i did stress tests, they are just fine, never had any trouble with them. its a build from store, i dint changed the ram.

Anyway, i will try owerclock it my cpu, by using modified BIOS to disable intel speed step and use higher multiplyer. Should i owerclock my RAM to? i did owerclocled my graphics card already.

 

If you are overclocking the CPU by upping the FSB, unless you can change the RAM frequency to FSB ratio, you will be overclocking the RAM as well. This might hold you back unless you modify the timings and etc, but that is another story. But to answer your question, overclocking the RAM will have a negligible improvement.
