The BIOS adjustments of the A8R-MVP were a pleasant surprise for a low-end board, but they were not as extensive as those seen on top-end Asus boards like the 8-phase A8N32-SLI. The BIOS for the A8R32-MVP is very complete, and does not really have any Asus high-end adjustments missing at all. The available adjustment ranges have been improved over the available options on the A8R-MVP, and Asus has added more options for processor and chipset voltages.

As on the A8R-MVP, memory voltage can be adjusted from 2.5 to 3.2V - much wider than most boards and the equal of the Asus A8N32-SLI. The A8R32-MVP adds finer memory voltage adjustments, in 0.05V increments. Memory voltage does not extend to 4.0V as it does on the DFI, but the only memory requiring these high voltages is OCZ VX and Mushkin Redline, both of which have been discontinued.

On the A8R-MVP, the available vCore options depend on the CPU installed on the A8R32-MVP. Our test Athlon 64 has a default voltage of 1.35V and the A8R32-MVP provided adjustments to 1.45V. A Clawhammer provided adjustments to 1.55V.

There is an important addition, however, in the vCore overvoltage option. This can be set to Auto, disabled, 100mv, or 200mv. This means that you can add up to .2V to any vCore settings that you can select in the BIOS. The A8R-MVP had just Enabled or Disabled for vCore overvoltage. The value turned out to be about 0.1V. With the added 200mv option, vCore can be adjusted up to 1.65V on our Athlon 64 specified to run at 1.35V. You should be able to achieve similar results of a .25V to .3V vCore overvoltage with any Athlon 64 processor.

Voltage adjustments are one area where buyers asked for more, and Asus has added quite a few new voltage adjustments with broader ranges in the A8R32-MVP. Northbridge Core voltage can be adjusted from 1.2 to 1.5V, as can HTT voltage, and PCI Express voltage.

The A8R-MVP has a very wide range of memory timing adjustments in recent BIOS revisions. Asus has expanded beyond these in the A8R32-MVP Deluxe. While the A8R32-MVP still defaults to a 2T Command Rate at Auto for widest memory compatability - it is now very easy to force 1T, even at high speeds. Unlike the A8R-MVP, which required 2T above 260-265, the A8R32-MVP supports 1T Command Rate to well over 300 Clock Speed. This is the kind of performance enthusiasts want on this board.

The RD480-based Asus A8R-MVP has a very wide range of overclocking controls for a board in the $100 price range, but it is weak in voltage adjustments and memory Command Rate settings. The RD580-based A8R32MVP, for the most part, corrects those deficiencies by providing finer adjustments, a larger number of BIOS-adjustable voltages, and higher vCore settings. Most users will be pleased with the additions and refinements. The A8R32-MVP stands up well against just about any overclocking board available in terms of the available overclocking options and the range of control available. The Asus designers did an excellent job of listening to buyers of the earlier A8R-MVP and adding the most asked-for improvements.

    NewEgg still doesn't have them in stock, neither does Monarc Computers. Wonder how long it'll be before they get them and the prices drop. Reply

    I've just gotten this mobo.. It's pretty sweet! I really like the ALC882 onboard sound! It's really crispy and all good :D

    Overall I don't have any issues with it. It's a damn good mobo!

    It is nice that manufactors listen, but why do they still bring out Motherboards for SLI and Crossfire, where the normal PCI cannot be used with their heigh end grafic cards - I am wondering ? Reply

    This board gets an official "daaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaamn, Gina!" rating.
    Holy crap it flies with an X1900XT!

    No one has any RD580 boards in stock in the US. Hell, Newegg doesn't even have any listed! Looks like another classic paper launch to me. Reply

    Please get a clue before posting. All these people complaining about not making proper comparisons because Anandtech went the extra step of testing the latest vid card from ati on their latest chipset in ADDITION to making a very fair comparison with what nvidia has to offer currently.

    Nice article, too bad people don't pay attention to the graphs before they complain about them.

    Moron. Did you happen to notice the "Out Of Stock" button?

    And what's with the bitching about proper comparisons, blah blah blah? Reply to the wrong thread, did we?
