Taiwanese hardware maker Biostar was also present at this year’s CeBIT fair, where the company showcased a couple of LGA 1155 motherboards based on Intel’s Z77 Express chipset, namely the Biostar TZ77EX3 and TZ77EX4.
Just as its name suggests, the TZ77EX4 is the more feature-rich model of the two since it comes with a more powerful 13-phase VRM as well as with some extra options.
12 of these phases are used by Biostar to power the CPU, while the extra phase was added to feed the four memory slots.
The board’s expansion features include three PCI Express x16 slots, one PCIe x1 and a pair of regular PCI slots, as well as eight SATA ports.
Four of these support SATA 6Gbps transfer speeds, two driven by the Intel Z77 chipset while the other two are controller by a Marvell chip, according to TweakPC.de.
As far as the PCIe x16 slots are concerned, only the first of these can work at full x16 speeds as the second one has only eight PCIe lanes routed to it, but these are compatible with both Nvidia SLI and AMD CrossFireX setups.
Moving to the back, the connectivity options available include everything that we expect to see from a high-end Z77 board, such as Quad video out (DVI, VGA, HDMI, and Displayport) and an eSATA port.
Biostar has also added two USB 3.0 ports that are driven by the Intel PCH, while two more such high-speed connectors can be routed to the front of the case by connecting them to the provided on-board header.
The more budget friendly TZ77EX3 includes pretty much the same features as its older brother, but in order to lower its price, Biostar decide to drop the two extra SATA 6Gbps ports, the DisplayPort video output and the high-end Pro Tone HD audio technology.
However, both motherboards come with on-board Power and Reset buttons as well as with a BIOS debug LED.
No details regarding the pricing or the availability of the TZ77EX3 and TZ77EX4 boards were provided by Biostar.
