The Biostar TForce4 U 775 is a member of the TForce4 Series product family and, as such, is a value-based board targeted towards the enthusiast user who is concerned about price and performance. The board ships with an accessory package that includes the standard assortment of IDE/SATA cables and power connectors. Biostar also includes a driver CD along with several desktop utilities for monitoring and tuning your system.

This is the main BIOS screen and it displays the generic options available on the board.

The Overclock Navigator section allows you to change the majority of the system performance settings. The system features the Auto Overclock System that will automatically adjust most system parameters based upon the components installed. The V6-Tech setting will overclock the system around 10~15%, V8-Tech setting will allow up to a 25% overclock, and the V12-Tech system will allow up to a 30% system overclock.

The balance of the Overclock Navigator section allows you to set individual parameters manually for voltage, multipliers, and chipset settings.

The board fully supports manual memory timing adjustments or allows for a Default setting that will set the memory to the SPD settings.

An additional feature on the board is the CMOS reloading program that allows users to save up to 50 sets of CMOS settings into the BIOS. The user is able to personalize each setting before saving it. The feature worked well in our testing, provided that we were able to reach the BIOS setting.

Overall, the BIOS options are very good for a chipset that NVIDIA has stated is not optimized for overclocking. The board's bios even includes a built in memory tester based upon Memetest86+ version 1.55. We would like to see more memory voltage options included in the BIOS along with the ability to adjust the PCI bus speeds.

    Haha! Way to go, Gary. You have a fan base! =P

    Thanks for kind words everyone. I will post a short update to this article in a couple of days as the new bios results are looking promising in resolving some overclock and bios lockup issues.

    Gary is awesome! :)
  • Zebo - Thursday, February 16, 2006 - link

    I love Gary can't we get him writing articles people will read? Intel/biostar - common.. you'll get 1000 page hits max and 3/4 of them are because Gary wrote it!:P

    Not too bad if you want a P4, but for me I am avoiding nVIDIA Chipsets except when it comes to AMD products. Go Go ULi!
  • DigitalFreak - Thursday, February 16, 2006 - link

    Uh, you mean Go Go Nvidia, since they own ULi now...

    Finaly Intel Gets Hypertransport on their chips, like it or not HTT probably is becoming a standard that Intel might have to adopt sooner or later.
  • DigitalFreak - Thursday, February 16, 2006 - link

    This has nothing to do with Intel. Nvidia uses HT to communicate between their north and south bridges. They've done it with all their Intel chipsets so far.
  • Googer - Thursday, February 16, 2006 - link

    Since the noth bridge has HTT, in theory you could connect an nVIDIA based nFORCE north bridge to a ULi or nVIDIA AMD north bridge and have one of several things:

    1) A dual CPU system- One Intel Pentium M/4 and One AMD 64 CPU running on the same motherboard simultaniously. The OS might need to be re-written so that multi-threaded applications only use one processor. Linux prehaps?

    2) AMD 64 Could get Quad Channel RAM higher.

    3) You could ADD a ULi M1567 Southbridge to get True AGP with that PCI-express SLI.

    4) You could possibly mix and match chipsets. VIA K8T8xx with one of AMD's north/south bridges and an nFORCE Intel Editon.

    You could possibly Connect the AMD 64 Directly (using it's own HTT link) in to the the P4 north bridge with no need to use the chipset designed for the A64.


    HTT on Intel means a whole new world of possibilites!
  • Furen - Thursday, February 16, 2006 - link

    Huh? How is Intel getting hypertransport on its chips? HT is a standard but I dont think Intel will ever adopt it because of its pride, more than anything else. It truly doesn't matter though, since HT is just a data transport and using any other data transport gives you the same results as long as it is used in a similar configuration.
