While the BIOS adjustments are not as extensive as the Asus A8N32-SLI Deluxe or the DFI RDX200, most of the adjustments needed for overclocking control are definitely here.

This includes memory voltage to 3.2V – much wider than most boards and the equal of the Asus A8N32-SLI. 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.

After our initial testing showed the A8R-MVP to be an excellent overclocker, we suggested to Asus that they support the higher memory ratios of the Revision E and above AMD Memory Controller and include additional adjustments for memory. Asus added the ratios and a few more memory controls, which will be available on-line as the board begins shipping this week.

The arrangement of options in AMI BIOS has not always been the most intuitive. You will find memory adjustments under “Advanced”, “CPU Configuration”, “Memory Configuration”, and “Memory Timing Configuration”. The logic of this menu nesting is obscure, but once you drill down to memory timing adjustments, you will find a fairly complete range of options. In most cases, you will need to change from “Auto” to “Manual” to bring up the adjustments.

    The PCIe giagbit cards should deliver the same performance as on-board PCIe Gigabit Ethernet. They generally use the same chips as on-board or variants f those chips. You can use the x1 PCIe slot with Crossfire IF your cards are single width. If the video cards are double width the PCIe x1 is blocked.

    We have a Syskonnect PCIe Gigabit Ethernet card and it uses the Marvel 88E8052 chip.

    ...just wrote them basically begging for availibility info on this board. Anand's article has gotten me very very hyped for this product as a cheap SLI replacement for my MSI Neo4 Ultra -- HALF the price of an A8N32 seems like it can't be beat. For all that's worth, however, I still haven't found a single user experience with this board -- have the lucky people who have it (if there are any) forgotten about the internet?

    It is now in stock at newegg

    This board looks good for a HTPC, but I have one question about the HD audio, you do not mention if this board will do a real time encode of Dolby Digital on that coaxial SPDIF port. My minimum requirements for a HTPC main board include passive cooling and Dolby Digital out either optical or coaxial to connect with my home theater receiver. I would appreciate a standard line in each motherboard review that makes the Dolby Digital out capability of each main board clear.

    Keep up the great work.

    Man all these sweet deals at newegg but don't have this board yet :(

    thanks for all the updates, wes!

    This looks like the perfect Socket 939 board. It's fast, passive-cooling, great overclocker, and cheap!! Even uses the ATI chipset and is built by the biggest board maker in the world, so how could I go wrong. Just put 2 on order at Buy.com. At $105 each they seemed like a perfect board for some Christmas builds.

    Is'nt most of chipset in AMD CPU these days? I would'nt worry about that.
  • xsilver - Thursday, November 24, 2005 - link

    does asus ship this board with overclocking software for overclocking while booted in windows? what other mobo companies offer this? (I find this feature very handy on my abit)
    its most convienient to boot up and surf and run stock speeds and then overclock to play a game and then change back when you're finished

    I know utilities like rmclock and cpucool can do this but they dont work for all mobo's
  • Wesley Fink - Thursday, November 24, 2005 - link

    Yes, Asus includes some very good windows-based OC software with the A8R-MVP. AI Booster allows the control of OC in windows, and PC Probe 2 allows fan control and voltage/temperature monitoring. AMDZone descibes these software utilities in their A8R-MVP preview at http://www.amdzone.com/modules.php?op=modload&...">http://www.amdzone.com/modules.php?op=m...q=viewar...
