Asus A7M266-D, MSI K7D Master-L and Tyan Tiger MPX in the test: First look at AMD's dual mainboards

The Tyan Tiger MPX

In a dual processor mainboard test, a mainboard from the old master for dual mainboards, Tyan Technologies, must of course not be missing. We were able to take a closer look at the Tiger MPX. Unfortunately, like the Asus board, the Tiger MPX still has the Southbridge bug. Use of the on-board USB interfaces is possible, but AMD does not recommend it, as this can lead to data loss. As usual from Tyan, the mainboard looks very clear, almost empty. In direct comparison with the other boards, one notices that Tyan has packed very few connections on the board. Unusual for others, normal for Tyan, the many connections for fans. Tyan put six of them on the Tiger MPX. Tyan wasn't even with the PCI slotsstingy, the Tiger MPX is the only board in the test field to have four of the normal 32bit/33MHz slots in addition to the two 64bit/66MHz slots.

Tyan - Southbridge

Even with the Tiger MPX you are forced to mount normal 60x60 cm coolers. Larger coolers are practically not possible here. The large capacitors, which form a row between the sockets, prevent any installation of large and powerful coolers.

Tyan - fan environment

Tyan came up with an interesting idea in connection with the power supply. Instead of the additional 4-pin power connector, as is common nowadays, there is a socket for a common drive connector. What causes incomprehension in the first moment is useful in the second. The advantage of this concept is obvious. With the Tiger MPX you don't necessarily need a new power supply, no, you can continue to use your old ATX power supply as long as it has enough power for a dual AMD mainboard

Tyan - power connection

As mentioned above, it works Spartan at the connections too. In addition to the mandatory connections for the printer and two serial interfaces, there are also two USB 1.1 interfaces and the LAN connection,here Tyan opted for a 3COM chip (3C920C), available. Since the Tiger MPX does not have a sound chip integrated on the board, the connections used on the other boards are missing.

Tyan - External interfaces

Equipment & scope of delivery

There are also none with the Tiger MPX from Tyan Special features of the scope of delivery. The already mentioned two cables for the drives, a cover plate for the external connections as well as a driver CD and a USB 2.0 PCI card are the only ones to be found in the box next to the manual and the mainboard.

As spartan as the mainboard itself, this is also how it looks in the BIOS. Even after repeated searches, no menu item could be found with which you can check the status of your mainboard, such as the temperature of the CPUs or monitoring the speed of the fans. This is surprising, especially since the previous model, the Tiger MP, had this option.

Tyan - Bios

All the more unusual for Tyan, setting options for the front side bus. Tyan lets the PC user set the front side bus (FSB) in 9 steps from 133 MHz to 150 MHz.

Tyan -Bios

Another point that is not noticed right at the beginning is the lack of the possibility to switch off the shadow functions. In particular, the video bios shadow and the system bios shadow function are permanently switched on in the Tiger MPX and cannot be deactivated.
