I850 overclocked Vs I875/SIS655TX

[andreribeiro]

I currently own an Asus P4T-E with Intel 850.

I found a tutorial that told me how to use Nortwood's B CPU's (FSB 533) in with PC1066 RDRAM in this board.

The best processor that I can buy and still mantaining the same motherboard is a P4 3.06 GHz.

But my question is the following:

Would the I850 board with a P4 3.06GHz and RDRAM 1066, perform better than a I875 motherboard with Dual channel DDR 333 and the same processor?

and against a SIS655TX with Dual Channel DDR 400 and the same P4 3,06GHZ?


Theoraticaly yes because DDR400 ==> 6,4 GB/s
and Dual PC1066 RDRAM ==> 8,6 GB/s

Am I right?

Unfortunatly in this case max bandwith means nothing. In both cases you will be able to match or overshoot the max bandwith of the fsb. So bandwith is out of the picture. Next we move to latency...a shortcomming of rdram. I think a pat enabled 865 mobo, an 875 mobo or a sis655tx mobo would be the best choice...

Also you will still be limited to 533mhz fsb cpus with the 850 chipset, and if you have seen the latest benchies the added fsb bandwith really helps!


If it isn't a P6 then it isn't a procesor
