Biostar TZ77XE4—Visual Inspection

With memories of Biostar fresh in my mind from the 990FX roundup, I have another chance to tackle a motherboard from them. This one comes in at more of a premium than the other—at an MSRP of $169 it is not the cheapest board this time. However, it does seem to have learned some lessons with the PCIe layout at least, but in terms of features we are perhaps a bit lacking.

Biostar have characteristically been black and orange, and we see it here again on their top Z77 model, the TZ77XE4. Power delivery is essentially a 10+2 (CPU/iGPU) system with large brightly colored heatsinks to remove heat, both connected via a heatpipe. These heatsinks are set a little away from the Intel designated socket area, though the memory banks are right up against the boundary—with only two sticks of memory in the board there will be enough room for most of the beefiest air coolers.

In terms of fan headers, Biostar have unfortunately put much effort in here, with only three to play with—a 4-pin CPU fan header to the top right of the socket, and two 3-pin at the south end of the board. Anyone requiring headers for fans will have to resort to providing their own fan control.

Along the right hand side, apart from the 24-pin power connector, we have a series of eight SATA ports—two SATA 6 Gbps from the PCH, four SATA 3 Gbps also from the PCH, and another two SATA 6 Gbps from an ASMedia controller. These are unfortunately not color coded, meaning users will have to double check every time that the SATA cable is going into the port as intended. Below these, we have a two-digit debug display for error reporting.

The chipset heatsink sports the bright orange Biostar color, but is rather small which could lead to it being warm to the touch. On the south side of the board, we are not exactly bursting with headers—aside from the fans, we have front panel headers, a pair of USB 2.0 headers, and power/reset/clear CMOS buttons. These buttons are all similar and next to each other, so I can just see myself accidentally pressing the wrong one from time to time. It is also important to note the location of a USB 3.0 header, just above the third full-length PCIe slot. This is a rather awkward place, and cements its use primarily for rear facing adaptors (as long as there is nothing in the PCI slot beside it).

The PCIe layout is better than previous iterations, featuring an x16 (x8 in dual-GPU), x1, x8, PCI, PCI and Gen 2.0 x4. This leaves a space between GPUs, and a spare x1, PCI and x4 when dual GPUs are being used. Note we do not have a molex connector here, suggesting that Biostar are happy with the power delivery when the PCIe slots are in use.

For back panel functionality, we have a PS2 keyboard port, two USB 2.0 ports (black), DisplayPort, HDMI, D-Sub, DVI-I, eSATA, two USB 3.0 (blue), gigabit Ethernet, two more USB 2.0 (black), and audio jacks. I should stress that even though there is a DVI-I on the back panel, it does not accept analog signals by adaptor.

Aside from the extra SATA controller, PCI slots, Power/Reset buttons and the use of all four display outputs, there's nothing much 'extra' that Biostar have put on the board which isn't already in the default chipset. This could perhaps be their downfall when it comes to conclusions after testing.

ECS Z77H2-AX Features To Watch Out For

    They've yet to fail me. I think I may take the plunge with Ivy Bridge. My 920 X58 build has served me well, but I have the itch and I've avoided scratching it since late 2008. I don't think I can hold off any longer!!!

    I feel the need for a new build.....NOW!!!
  • TrackSmart - Sunday, April 8, 2012 - link

    Ha ha. We all get the rational or irrational urge to upgrade, whether we 'need' it or not. I would never stop someone from enjoying a new build. But that being said, the core i7 920 still holds its own pretty well. However, I suppose quicksync alone could be worth the upgrade if it is a feature you use heavily. That is one area where the performance gains are just phenomenal. Reply

    Shoot, I'm still rolling with an E8400. You're 920 has some legs.

    Unless you have a killer app in Ivy Bridge, just sit on your Nahalem machine.

    Believe me fellas. This is all irrational and I'm not ashamed to admit it! Reply

    Like :)

    I'm torn between waiting for Haswell next or upgrading to Ivy Bridge now.
    I'm on a E7200. Hahaha

    ...and I am burning this E6750. :D

    I give up. Time to upgrade. :)

    Rockin the Core 2 on the 975x with an 8800 gtx here :D
  • LancerVI - Monday, April 9, 2012 - link

    That's awesome! That's a great setup! The 8800GTX is on par, in my mind, with the 9700 Pro of yore. Reply

    920 X58 being slow???? I have an AMD FX-60 Dual core with 2GB of DDR ram....That is slow.... :) Reply
  • LancerVI - Thursday, April 12, 2012 - link

    Who said anything about being slow?? All I'm saying is I haven't built a new machine since 2008 and I have the itch.

    I realize it's a slight up grade or maybe even considered a side-grade, but it's an itch. I'll probably wait unitl Ivy Bridge-E and then see.
