BIOS Features: ATI Bullhead

It is rare that we would want to show the BIOS options for a chipset in more than basic features, but the options available to the reviewer are unusually complete on the ATI Bullhead.

ATI chose the AMI BIOS, which is used by Asus and many other manufacturers on their AMD Athlon 64 motherboards.



Since the ATI RX480 is designed for qualification, you may not see the same range of tweaking options on shipping boards. However, it is worth showing some of the more interesting options from the BIOS, just so readers will know that they can be implemented on an ATI RX480/RS480 board.



Many tweaks can be found in the Advanced Menu. This includes many of the features of interest to overclockers.



As you can see, the AMD Overclocking section has adjustments for Ratios, CPU voltage, clock speed, Hyper Transport Speed, Auto-Tuning, and PCIe clock.



Memory timings and voltage are found in the Chipset, Northbridge menu.



Memory tweaks even include a User Config mode with additional memory adjustments. The Memory controls are among the best that you will ever see in an Athlon 64 BIOS.



The Southbridge controls include a range of options for the integrated peripherals...



...and a Southbridge Debug Configuration menu.



For RS480 chipsets, you will also find an RS480 menu under chipsets. Options in the RS480 allow control of the integrated graphics and graphics related options like SurroundView.

The point, of course, is that ATI supplied the ATI Bullhead loaded with the kinds of options that reviewers need to get the most out of the RX480/RS480 chipset. With a full range of options and wide adjustment ranges, we couldn't wait to see where we could take the Bullhead in overclocking.

    Hmmmm, still no real availability even now...Looks like MSI may be our only chance at this chipset....what as bummer :(

    Hmmm, after no real availability (in the US at least) as of Friday 2/18/05, there's suddenly a slew of shops selling the MSI board on pricewatch, including Newegg. Anyone know of a reason why the boards are so slow to trickle out?

    Is it possible to purchase these reference boards? I seem to see them in retail-looking packages in reviews from Canada.
    If you can get your hands on one, are the BIOSes available to the public, or only to the select HW review sites?

    PERFORMANCE WITH 4 DIMMS CORRECTED>

    We have added the following update to p.6:

    "UPDATE 11/11/2004: ATI has provided an updated BIOS which corrects the issues of 333 timings with 4 double-sided dimms. With the new BIOS we were able to run 4X512MB DS OCZ 3200 Platinum Rev.2 at 2-2-2-10 timings at DDR400 with a 2T Command Rate. This performance matches the best we have seen with 4 DS dimms on an Athlon 64 motherboard."

    #35: I'm right there with ya, bud. Just when I "think" I've made up my mind to do the complete overhaul, the next exit appears on the highway taking me that much closer to the "Best Soft Serve in Town"!!

    The ol' gut tells me to hold out until some time just after the ball drops in Times Square and we'll all be in Fat City, so to speak. ;)

    Somewhat OT maybe:

    anyone seeing a reason that the next rev of A64 supporting SSE3 (in market Q1/05) coul not be plugged in a 939-mobo (nvid, ati or via) without problems (except any necessary BIOS update) ?

  • callius - Tuesday, November 9, 2004 - link

    Only minus vs nforce4 is that the SB does not support SATA-II's NCQ (for Seagate's upcoming 7200.8 series). Maybe with next SB in Q1/05 though ???
  • mlittl3 - Tuesday, November 9, 2004 - link

    Completely off topic, but does anyone know why there are four chipsets (two actively cooled, one passively cooled and the other with no cooling) in the SLI Tyan motherboard that #33 gave a link for?
  • xeper - Tuesday, November 9, 2004 - link

    i can't seem to find ANY mention whatsoever of shared memory allocation. can someone help me out here?

    Isn’t this very funny, I mean Ati was a very close partner to Intel, and they now bring to intel its one competition product but for the intel competitor.

    I see now no reason for Dell or other companies go for intel, because really intel had (has) the edge with integrated solutions.

    A "part" I thought that there weren’t AMD IGP chipsets because it wasn’t possible to use the integrated memory controller for graphics, at least until AMD64 rev E0 came out?

    If ati is going amd on pcie first, these shows that amd have the best processor and will continue for the time been. Even dothan can do much to turn it around again to intel side. And i bet that new p4 2mb is still with problems (performance, heat, …) and every one is running away from intel because already know this even intel, bringing dothan to the desktop market.
