Memory Speed on New Setup Question


Euthanasia

Recommended Posts

Hello Ram Gurus; I have a question here. I am thinking of buying a system, and I am looking for the best performance possible; I was going to buy the following: Intel Core 2 Extreme QX6700 (which runs a 1066 bus), 4gb Corsair Dominator (which runs a 1066 bus (PC-8500)), and an Asus Striker Extreme (which runs the following bus speeds: 1333 / 1066 / 800 / 533).

 

My question is simply this: Should I be matching the CPU FSB, Motherboard FSB, and RAM FSB at 1066 MHz to get the best performance? Please advise me. Thank you so much in advance! :D:

That really depends on the MB more than the CPU.

DDR1 Memory runs at:

DDR-266 = 133 MHz 2 X 133 = DDR-266 PC-2100

DDR-333 = 166 MHz 2 X 166 = DDR-333 PC-2700

DDR-400 = 200 MHz 2 X 200 = DDR-400 PC-3200

 

DDR2 Memory runs at:

DDR2-533 = 266 Clock Frequency 2 X 266 = DDR2 533

DDR2-667 = 333 Clock Frequency 2 X 333 = DDR2 667

DDR2-800 = 400 Clock Frequency 2 X 400 = DDR2 800

DDR2-1066 = 533Clock Frequency 2 X 533 = DDR2 1066

 

Intel CPU:

400 MHz = 100 MHz Clock Freq. 100 X 4 = 400 FSB

533 MHz = 133 MHz Clock Freq. 133 X 4 = 533 FSB

800 MHz = 200 MHz Clock Freq. 200 X 4 = 800 FSB

1066 MHz = 266 MHz Clock Freq. 266 x 4 = 1066 FSB

 

However, with the MB and CPU you have I would suggest 2 modules at DDR166 for best performance.
