nForce details

[bug]

04.12.18
nForce5 (2Q2005) two chip design (C19 + MCP04 [IBM fab]) supports two PCIe graphic ports (SLI) and DDR2 (533 or 667MHz) memory, 1066MHz fsb 775-pin LGA P4 and 939-pin A64, USB 2.0, Gbit ethernet, Nvidia does not like to release info about "future" products... link link2

nForce4 (after Intel lost 6% of it's chipset marketshare lead to VIA, SiS and ATI) cross licensed (Nov 2004) Intel with Nvidia so Amd nolonger had exclusive braging rights. SLI (Scalable Link Interface) (two GF 6600GT or higher) and two other mobo variants, x16 agp, four sata and four parallel ata drives with raid (0,1,0+1,) Gbit ethernet, 775-pin P4 (@ 1066MHz [266MHz fsb "QuadPumped"]), 939-pin (@ 1GHz HT bus) and socket 754 (@ 800MHz HT bus reference ) AMD cpu, pci express fsb, (antique) AC'97 audio, .. Ultra model supports sata2 (3Gbps,) ten USB 2.0 and FireWire ports, hardware firewall, 8-channel AC'97 audio.

NVIDIA's nForce3 launched March 2004. And was largely to support AMD's 64bit cpu. The nForce3 MCP chipset (Media and Communications Processor) was set to release in six variants. 133MHz PCI bus, integrated Gbit ethernet and firewall, (limited Linux support,) four SATA150, eight USB 2.0 ports. link3

nForce2: (Nov 2002) "gamers" platform with ATA 133 ide & sata controllers, USB 2 & IEEE 1394a (firewire) support, dual-independent 64bit DDR memory controllers, x8 agp (2.1 GB/s,) 3D integrated audio (Dolby digital 5.1,) firewall, gigabit ethernet, twin bank memory architecture, raid (0, 1, 0+1,) HyperTransport bus interface, 333MHz fsb.

nForce1 (2001) for the 21st century, Nvidia knowing computers are used for applications other than word processing and spreadsheets intend their nForce chipset mobo to include broadband and 3D audio (Dolby Digital 5.1 [from MS xbox,]) IGP Northbridge (runs memory, video & processor functions,) MCP (Southbridge) supports pci & ide with HyperTransport (HT) communication AMD specification (allows for 800MB/s communication between MCP & IGP [3X faster than pci,]) memory controller (TwinBank Memory Architecture) offered 64bit or 128bit DDR (200 or 266MHz) interface (4.2GB/s bandwidth,) 10/100 Base-T networking / 56k modem support and USB interface. An optional integrated video processor (GF2mx) or AGP (?x6 speed) support for x4 agp slot gpu. (This was when other integrated mobo were doing 500 in 3Dmark benchmark & the nForce420 was doing +2500.)

? Are there any errors in these details on the nForce chipset mobo specs? So far i can not find where the A64 cpu memory controller support DDR2 nor the 1066MHz fsb, hence how the AMD cpu will factor in the nForce5 mobo.

Are there any errors in these details on the nForce chipset mobo specs? So far i can not find where the A64 cpu memory controller support DDR2 nor the 1066MHz fsb, hence how the AMD cpu will factor in the nForce5 mobo.

A64 has the memory controller in the CPU and as yet they are not supporting DDR2 and will just probably jump to DDR3 instead.

As for the 1066 FSB - the AMD64 doesn't have an FSB as such its got the Hypertransport system. Only Intel P4's will support 1066 Mhz in the near future

As for AMD factoring in the nforce5 boards they will not as they are for Intel Pentium 4 processors
