What is HyperTransport?

From the HyperTransport Consortium webpage is this following quote:

HyperTransport interconnect technology is a high-performance, high-speed, high-bandwidth, point-to-point link that provides the lowest possible latency for chip-to-chip links.
In Athlon 64 motherboard implementations HyperTransport is set relative to the LDT speed but is not directly associated with processor performance; increased HyperTransport speed means that bandwidth between components increase and conversely, latency should decrease. HyperTransport has been a source of confusion since the introduction of the Athlon 64 and hopefully this helps clear up the distinction between HyperTransport and the LDT bus. In the following tests, I benchmarked the system at HT bus speed multipliers of 5x, 4x, 3x, 2x, and 1x. The results for the tests performed at 5x, being stock-clocked results, are used in subsequent testings where we compare stock results to other results.
It's apparent that XviD encoding isn't dependant on the HT link at all. There was absolutely no change in the frame rate going from 1000 MHz to 200 MHz. Obviously this task is primarily delegated to the CPU and RAM, which are independent of the HTT link, and hard drive I/O, which doesn't come close to saturating even a 200 MHz HTT link.

The synthetic SiSoft Sandra scores take a slight hit as we drop the HT link speed, with ALU performance taking the largest hit with its measly ~1.5% drop. All in all, the scores remain pretty constant, as the performance hits are quite insignificant (although reproducible).

MP3 encoding, being a similar task to XviD encoding, also exhibits virtually no performance differences as we lower the HT link speed. Only at the very slowest speed of 200 MHz do we see a difference of 1 second.

In total, Half-Life 2 performance drops a total of 1 FPS. Nothing to see here, move along.

Much like Half-Life 2, Doom 3 dropped a total of 1 FPS.
All in all, we can see that a reduced HT link speed has an extremely limited impact on overall system performance, at least when it comes to our specific tests. When running at a speed of 1 GHz, the total theoretical bandwidth of the HT link is 6.4 GB/s. At 200 MHz, that theoretical limit drops to 1.28 GB/s. Imagining a block diagram of the nForce4 platform, it's obvious that this is sufficient for most of the devices that depend on the HT link to bring data to the CPU and memory, namely the Ethernet interface and hard drives. With AGP 8x having a peak bandwidth of about 2.1 GB/s, the 200 MHz 1.28 GB/s HT link is still a tad faster than AGP 4x (which we all know has yet to be saturated in most cases), meaning that the video subsystem ought not be too bottlenecked by 200 MHz either. One of more contentious issues after the debut of the Athlon 64 was the VIA HyperTransport implementation on the K8T800 versus the nForce 3 150 implementation. VIA's HyperTransport was faster and wider (a different number of bits transfered per clock is adjustable) but it looks like a lot of those criticisms were largely unfounded as NVIDIA suggested at the time.

Update kết quả cuối cùng của con này ( vì thấy có 1 người đang hỏi về con này nên muốn rõ ràng hơn )

- OC CPU : với Vcore 1.65v max , đủ để oc CPU nếu ko chơi hardcore :D , điện đóm đã ok với Bios 0311

- OC RAM :beo:
- Lỗi freeze ở Game đã fix với Bios 0311

* Bios sucks , support OC Ram bèo nhèo , Tref chỉ có 3 giá trị : 3.9ns , 15.6ns , 7.8ns và set trong Bios 1 đàng vào Windows nó ra 1 nẻo :lemat: , chưa nói tới ko có các giá trị Refresh ( vd 200 , 166 , 100 .... ) ---> chuối vãi

* Divider ko có 140 , 150 :lay:
* Data drive strength ko có , chỉ có drive strength :beo:
* ko có idle cycle timer
--> Bios lỗi tè le

Với con Kíngton Value UCCC 2x1GB thì con Asus chỉ chạy đc @ 200 2.5-3-3-8 , còn lại oc cao hơn bus 233 là unstable ( ko vào đc Win luôn )
Trong khi với con DFI NF4 thì đã oc ok ở 245 3-4-3-8 :somot:

===> Con main này layout rất ok , linh kiện tốt , chỉ duy nhất là Bios củ chuối , nếu Bios ngon hơn thì nó cũng ko thua kém DFI --> Asus cần thuê thêm vài người viết Bios pro như OW của DFI , còn ko chẳng bao giờ khá nổi :beo:

Lời cuối : tôi đã trả con main này lâu rồi :beo: :lay:

à còn cái bug ngu ngốc nữa quên chưa nói

Khi xài con này pà kon nhớ đừng restart máy hay tắt máy nha , để nó chạy 24/7 là ok nhất , vì ...... :

- nếu restart hay tắt máy thì nó sẽ tự trả lại các setting DF hết :kinhdi: , giống như là Bios load DF vậy , vì vậy cho dù ko oc cũng chết người chứ đừng nói dân Ocer

- Khi nó bị như trên , muốn oc lại như cũ thì fải làm từ từ :
* kéo HTT lên 20MHz sau đó save , thóat ra reboot
* lại vào Cmos kéo HTT thêm 20Mhz ..... cho tới khi tới mức HTT mình cần oc :lemat:
* Trong lúc đó cấm chỉnh setting Ram hay v.v... , sau khi kéo HTT rồi mới vào chỉnh Ram
* Chỉnh divider và Vdimm trước , sau đó lại save , reboot
* Vào chỉnh tiếp timings ......

Nếu ko làm từng bước như trên , kéo cái rẹt hay chỉnh cái 1 setting oc của mình là coi như khỏi boot , chỉ có cách clear Cmos và làm lại từng bước giống như trên

Nói chung là nếu bạn lỡ restart hay turn of PC là coi như tốn ~ 15f chỉnh để oc vào Windows :lay: :beo:

==> Asus = Asuck , chưa từng thấy con Bios nào ngu như Bios con này

Ok I made a video. To show that the A8R32-MVP Deluxe doesn't boot up after you shut it down and turn off the power(bios was not touched - CMOS cleared before making the video): http://www.mytempdir.com/554736

Enjoy..........
