Nforce4

[Solitude]

Just went over nForce 4 spec, man the thing is a BEAST, of course gotta get the nForce4 SLI, support two GPUs and I think the nForce 4 also can run mix raid w/ ATA or SATA. Man the thing can dish out a can of whop ass for any Gamer.

For a long time, I always though AMD was playing catch w/ Intel. Esp, with the 800 FSB Intel has. Anyone know what the FSB on the nForce 3,4? Furthermore, can someone explain to me what the he!! is hyper transport, thanks. I also nForce 3 250 GB is better than the reg. 250, could someone tell me why? Why is nf3 250 better than 150?

First paragraph: Astro Turfing. Second paragraph: trying to cover it up.

There's a whole section of articles that covers this: http://www.anandtech.com/mb

AMD on their AMD64's have the memory controller in the cpu itself and it runs at the full processor speed so the 800 fsb of Intel is smoked. Of course the HTT (think of it as FSB) is at 800ddr (1600) or 10000ddr (2000) so a lot of people consider it the fsb of AMD64 chips

nForce 3/4 doesn't have an FSB
The memory controller is on the chip, which means the FSB frequency is essentially whatever the CPU is running.

Memory frequencies are forced to be "in sync" with the CPU frequency by only allowing memory speeds that are CPU frequency divided by an integer.

The link between the CPU and bridge chip (chipset) runs at either 800 or 1000 MHz for 3.2 to 4.0 GB/sec full duplex bandwidth.

The primary advantage of the 250 over the 150 is the overclocking options. the 250 allow a locked AGP/PCI frequency, which allows much higher HTT frequencies (the frequency that is multpilied by the processor multiplier and the HyperTransport multiplier) Since A64s are locked from going to higher multipliers, this is the only way to overclock them. 150 chipsets were generally limited to around 10-20% overclocks because of the AGP and/or PCI bus limitations, but with AGP/PCI locks on the 250 people are taking 1.8 GHz chips up to 2.4-2.6 GHz range for 30%+ overclocks.

. Anyone know what the FSB on the nForce 3,4?
--------------
Average 300Mhz depending on mobo. DFI's can do in excess of 350...Asus had trouble with 280. BTW it's officailly called "HTT" but we all say FSB still.


Furthermore, can someone explain to me what the he!! is hyper transport, thanks.
--------------------------
Fast communication to other stuff. Like 1000+ mhz...useful in on board mem controller and dual CPU.


I also nForce 3 250 GB is better than the reg. 250, could someone tell me why?
----------------------------
Supports Firewire, built-in firewall, and some other snazy suff



Why is nf3 250 better than 150?
-----------------------
See above plus it runs a faster mem controller 1000Mhz vs. 600.
