DDR Question

[az]

Chrono, you've left out one step for RAMBUS: It doesn't run at true 800 MHz, but on 200 MHz (or 266, for PC1066) quad-pumped (or QDR, if you prefer that)

But let's not confuse sethos more than he most likely is now

Rambus appears in now 2 flavors.
PC800 is for 800Mhz (200Mhz QuadPump)
PC1066 is for 1066Mhz (266Mhz QuadPump)
PC800 is really only 100Mhz because you are using 2 channels, PC1066 is really only 133Mhz for the same reason.
So if you do the math its 2 (number of memory channels)*100 (P4 REAL FSB _until_ P4 2.26Ghz)*4 (quadpump) => 800.
If I were you I'd wait till mid may to by myself a new system composed of P4 running FSB800Mhz and a mobo with a chipset running dual DDR400. This should kick some a**es.

Ok...

So it's clock * 2 then that * bit rate and that's the sort that I need yes??

PS... At this point this is more for understanding than need, as I found out the kind that I need *whew*

ROFLMAO.

QDR goodness

Hey, QDR is really the correct technical term. It's "Quadruple Data Rate"

Actually the best performing boards are still equiped with RDR technology... but it comes with a price. So to sum it up RamBus still holds the speed crown, DDR400 just a pace behind. But for the price go for DDR400, it's close 2 times cheaper.
