Basic Features: Asus A8R32-MVP
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.

This doesn't make sense: "there will never be another Asus product purchased by our company". Why would a business care about overclocking? A business should care about STABILITY.DigitalFreak - Friday, February 17, 2006 - link
They should have moved the only PCI-E 1x slot to the left. They way it is now, you lose that slot when using a dual slot cooler in the PCI-E 16x slot closest to the processor. Hopefully that will be changed on the AM2 version of the board.aguilpa1 - Friday, February 17, 2006 - link
a 7800 and 1900 this way we can better gauge the mean performance of the "board" with identical comparison to other previously tested boards because not everyone is going to run out and get a $600 1900 ATI just for this board.Wesley Fink - Friday, February 17, 2006 - link
We DID test the A8R32-MVP with both the X1900XT and the 7800GTX. If you closely at the standard gaming performance graphs on p.9 you will see the orange bars are the A8R32-MVP test eith the X1900XT and the green bars are the same A8R32-MVP tests with the 7800GTX. The other board results are with the 7800GTX so if you compare the green bar to all the blue bars you are comparing 7800GTX performance on ATI and nVidia. In addition, all the bars are labeled with the test board and test video card to prevent confusion.This is explained in Test Setup on p.6, and in my comment above, "We reported both results so you could compare 7800GTX performance to the previous boards also tested with the 7800GTX. Since the X1900XT is the latest and fastest video card the results were included for Reference only. As someone else pointed out, when testing Dual X16 Video you have to run SLI on nVidia and Crossfire on ATI (or Intel)."

never mind, I see someone asked the same question, but were not given a reasonable answer anywaysBPB - Friday, February 17, 2006 - link
This is exciting news. But I plan on getting the X1900 AIW, which won't do Crossfire. So, when are we going to see non-Crossfire (Xpress 200-type) versions of this chipset? In the end I may get this board, but I'm hoping I can save a few bucks by getting one without the added cost of Crossfire.Wesley Fink - Wednesday, March 1, 2006 - link
RD580 is only available as the dual x16 version. With both x16 lanes off the north bridge you can't really leave out a chip, as you can in the nVidia version right now, and lower the price. The single X16 slot and dual x8 Crossfire will be provided by RD480.n7 - Friday, February 17, 2006 - link
Looks like a superb motherboard for the price!Zebo - Friday, February 17, 2006 - link
Look perfect to me. Black, high clocker, built like a tank and relativly inexpensive. I wish they had this two months ago - U seen my DFI chipset mod what a PITA to get silent chipset sitting right under card.:( Not only is ATI chispet seemingly cooler leaving us with passive solutions they clock at least as well if not better.Zebo - Friday, February 17, 2006 - link
Also the gap between PCIe cards is perfect to run water blocks too and well as nV/ATI silencers w/o touching or being cramped..
