請注意上面的網頁寫著....

HyperTransport™ Technology
Provides a scalable bandwidth interconnect between processors, I/O subsystems, and other chipsets
Support of up to three (3) coherent HyperTransport links, providing up to 24.0 GB/s peak bandwidth per processor
|
是"up to three(3)",而不是"all three(3)"....BTW,根據 S939 data sheet第14頁中寫著....
引用:
2.5.1 HyperTransport™ Technology Overview
The processor includes a 16-bit HyperTransport™ technology interface designed to be capable of
operating up to 2000 mega-transfers per second (MT/s), resulting in a bandwidth of up to 8 Gbytes/s
(4 Gbytes/s in each direction).

Desktop版的Opteron既然是插在S939上的,pin out應該也是依循S939的pin out吧----就算北橋內建一個以上HT,恐怕也沒pin可以拉到MB上  ....另外依據 S940 data sheet中第11頁寫著....
引用:
2.4.1 HyperTransport™ Technology Overview
The processor includes up to three16-bit HyperTransport™ technology interfaces capable of
operating up to 1600 mega-transfers per second (MT/s) with a resulting bandwidth of up to 6.4
Gbytes/s (3.2 Gbytes/s in each direction). Refer to Table 1 for product-specific details on
HyperTransport™ interfaces. The processor supports HyperTransport™ technology synchronous
clocking mode. Refer to the HyperTransport™ I/O Link Specification (www.hypertransport.org) for
details of link operation.

Product Number of Interfaces
Maximum Number of
Coherent Interfaces
Desktop 1 0
Server/Workstation Uni-Processor (UP) 3 0
Server/Workstation Dual-Processor (DP) 3 1 See note1
Server/Workstation Multi-Processor (MP) 3 3
Notes:
1. Coherency is supported on any one of the three HyperTransport™ interfaces on Server/Workstation DP products
