400fsb vs 800 fsb 800 twice as fast ?

Just thinking of building a new PC.

Based on a P4 3.0ghz cpu with Hyperthreading

What kind of ram would i need to take full advantage of the 800mhz
fsb ??

I want to run it in sync with the bus don't intend to overclock, just
want it nice and stable.

Thanks.

 

It's not really 800MHz FSB, it's really 'only' 200Mhz..........so PC3200
will run in sync.

I just built 2 with a 2.8c. I went with the Kingston HYPER X 3500 on one
and CORSAIR XMS 3500 on the other one. Both work equally well even
overclocking to 225 on the FSB with the memory in sync. The 3500 will run at
cas 2.0 where as anything higher wont,thats why i choose the 3500 and the
Kingston was cosiderablly cheaper. I bought the twin pack on the KINGSTON and
bought individual sticks on the CORSAIR because they ddint have any twin packs
available at the time. I would definatelt but at least 3500 unless you already
have some 3200. DOUG

 

pc3200 will do just fine. P4 system boards use what is called QDR quad
double rate so 200x4=800mhz

you mean quad DATA rate
(DDR = double/dual data rate, QDR = quad data rate)

PC3200 dual channel. For Intel FSB800, that works out to
6.4GB/sec.

Naturally, the Athlon FX-51 also has a HyperTransport link
that can push 6.4GB/sec but in the FX-51's case, that
link is not saturated with memory traffic (memory
controller is built onto the CPU die greatly reducing
latency).

So I guess the title to the thread is a question and the
answer is that the FX-51 is still faster. ;-)

 

And four times more or so

 

Bring on PCI Express, no FSB
