Questions about timings and DX48BT2...please help.

Hey there,

 

I just registered here and I am about to order a new rig. I did a search beforehand to find similar threads and I found out some useful info. However, I still have a few questions.

 

First question

DX48BT2 supports 1600MHZ on two DIMM modules which is fine as I will order DDR3 2x2gb @ 1600.

 

TWIN3X4096-1600C7DHX $514.00

TW3X4G1600C9DHX $234.00

 

Now both are the same speed but the timings are different. Do the timings really justify the price change? Performance wise at least? I am no memory expert so I am not sure the difference in timings make such a huge difference in cost, can you please explain?

 

Second question

 

I am going with the 45nm Quad Q9450 processor which supports only FSB 1333MHZ. Does this mean that my RAM will NOT be able to run at 1600MHZ because of that? Do I require an EXTREME processor that supports 1600MHZ in order to ensure my RAM runs also at 1600?

 

Should I generally just go with 1333MHZ RAM instead?

 

Please advice as I am about to order the parts today or tomorrow. Thanks!

A: The C7 part will be faster and over clock better.

A: Depends on if you want to over clock or not if you do not want to over clock I would go with 1333C7 modules for best performance.
