When Asus first introduced the A8V Deluxe it was the only Socket 939 board we had received with no AGP/PCI lock. Asus did not advertise an AGP/PCI lock and, in fact, it was not even listed as an option. When we talked with Asus about why they would leave out such a key feature of the VIA K8T800 PRO chipset, we were told Asus had concerns about the stability of the feature, and would not release a board with a lock until they were confident of the stable operation of the feature. While we did receive several prototypes with impressive performance and a working lock, Asus US did not give us the go-ahead that these interim designs would ever become production boards. For that reason, we did not believe it was fair to AnandTech readers to review an excellent design that they might never see in production.
Several weeks ago, Asus advised that they had completed a new Revision 2.0 with a number of board refinements and a working PCI/AGP lock that would soon be released. We had been very pleased with the revisions of the A8V we had evaluated, so we had great expectations of Revision 2.0. As you will see in the performance numbers and overclocking of the Asus A8V we were not disappointed.
The A8V Deluxe is the top-of-the-line Asus board for Socket 939, as you see reflected in the feature set. The A8V can be considered an update of the successful Asus K8V with the significant addition of the VIA K8T800 PRO chipset with, finally, a working PCI/AGP lock. Asus tells us that Revision 2.0 is more than just the addition of a production PCI/AGP lock, as they also used the update as an opportunity to refine the design.
As the Asus flagship Socket 939 the A8V Deluxe provides all the expected VIA K8T800 PRO/VT8237 features like 2-drive SATA RAID, 8 USB ports, and Hyper Transport to 1GHz. In addition Asus adds Marvell Gigabit LAN, The Promise PDC20378 RAID controller supporting 2 more SATA drives plus an additional IDE connector, Firewire, and the Realtec ALC850 8-channel codec. Asus calls their top boards AI, and the A8V includes a long list of proprietary Asus AI features like C.P.R., AI Net, AI BIOS, EZ Flash BIOS, and Q-Fan 2 fan-speed controls. The A8V also fully supports AMD Cool'n'Quiet.
Too often, we forget to mention that Asus is a huge proponent of Wi-Fi, and most of their boards include Wi-Fi capabilities. The A8V Deluxe is another Wi-Fi Home board, but the included adapter is now the higher-speed Wi-Fi G instead of the older and slower B standard. Asus even includes a desktop antenna to ease your communication with a wireless router or to serve as host for other Wi-Fi computers.
The overclocking controls are excellent in their range as we have come to expect on Asus boards. Noteworthy are the ratios in fine 0.5x ratios which makes OC fine-tuning that much easier on 939 CPUs. The CPU voltage also covers a very wide range from 0.8V to 1.80 volts. Our only complaint here is that 300 CPU Clock is a little short for a board that can do 289 at 1:1 memory, and the memory voltage controls are really limited at a top of 2.8V when we have performance memory warranted to 3.0V. Otherwise the variety and range of BIOS adjustments is excellent.
The layout of the A8V Deluxe is excellent. Both the 20-pin ATX and the 4-pin 12V connectors are on board edges and don't interfere with the CPU. The IDE connectors are in our preferred upper right edge of the board. Some will hate the floppy edge connector, but we liked getting it out of the way, and the floppy is also a connector many users don't use any way. The 4-dimm connectors, for up to 4GB of Dual-Channel memory, are well clear of the AGP 8X slot when changing memory. Asus is an advocate of quiet, failure-free passive chipset cooling, and you will see that in the massive heatsink used on the Northbridge. There's little to complain about in the layout of the Asus A8V Deluxe Rev.2.
Rear panel I/O is also very complete, including 6 audio mini jacks, both optical and coaxial SPDIF outputs, 4 USB, LAN, Firewire, 1 serial port, parallel port, and the usual PS2 keyboard and mouse ports. We were particularly pleased to see easily accessible optical and coax SPDIF ports and wish other manufacturers paid as much attention to this feature as Asus has in their recent board designs.

In compiling benchmarks for the upcoming 925X roundup, we realized we had used a different setup for our 925X AutoGK tests in this review than the setup for 939. This caused lower results with the 925X than we achieved with the same setup.AutoGK results have been corrected, and now show essentially the same encoding performance with the DivX 5.1.1 codec on both Intel 560 and AMD FX53 processors with a slight advantage to Intel. Tests with the Xvid codec show almost the same equivalent results with a slight tilt toward AMD.
Graphs and review text have been corrected to reflect the corrected encoding results. Current AutoGK settings are 'no audio' and default '2CDs (1400Mb)' output size. We install and select Divx 5.1.1 instead of the included Xvid codec. Ripping is from the original DVD file for Chapter 9 of "Sum of All Fears". At present we use the latest release version of AutoGK, which is 1.25, though there are beta versions available through 1.48.

#61 - You are mistaken in saying we used the SAME CPU in comparing 875 and 925X. If you will check our review at http://www.anandtech.com/cpuchipsets/showdoc.aspx?... you will see that our comparison #2 was a 3.2E on the 925X to a 3.2 Northwood on 875. In fact we got a lot of flak from some readers because we didn't use the same CPU. We felt then, and still feel, the fairest comparison was the 875 with Northwood to a similar speed 775 with Prescott.Our options on 939 are a 3500+ (512k cache) at $500, a 3800+ (512k) at $700, or a FX53 (1MB cache) at $763. AMD is expected to announce price reductions soon, but those are our current 939 choices. Given those 3 options with prices beginning at $500, the FX53 is an easy recommendation.

Arrggg.Interesting numbers but I hate the fact that Anandtech keeps using the FXxx and only the FXxx. Sure I can now see that AMDs best wins over Intel's best but that is not really practical because I will never buy an FXxx. I want benchmarks between stuff the average consumer is going to buy. Most people including me are struck between.
875/865 and Northwood (non EE)
925x/915 and a Presscott (non EE)
AMD64 754 vs 939 chips and chipsets but NOT the FX series.
These testbeds have only added to a string of Anandtech blunders. Remember the 925x review which was supposed to compare the 875 against the 925x? Well to elimate as many variable as possible, you use the SAME cpu, not a Northwood in one and a Presscott in the other.
I love Anandtech and I usually only come here for reviews but I really wish the staff would put more scientific thought into their testbeds. I will never buy an FX series processor and neither will most people because they cost way too much. At least you can throw in a testbed or two of some processors that the common man will actually buy.
Hope this critical post circulates with the staff and is actually taken into consideration.

Would there really be any point in providing FSB adjustments above 300 on say the MSI K8N mobo?As far as I know there are only two reasons for increasing the FSB-- increasing the memory speed, and increasing CPU core speed on non-FX chips which don't have an upwardly adjustable multiplier.
Theres no point in increasing the FSB beyond the point where the memory can run at a 1:1 ratio, and your fastest DDR550 memory was only able to hit 290FSB (DDR580). Unless faster DDR memory becomes available (which seems unlikely as the focus for speed will switch to DDR2), then 300FSB is more than enough.
The only other reason for increasing the FSB would be if you were seriously overclocking a CPU. 300FSB is enough for a 50% overclock which is more than enough for anyone. Maybe if someone got the liquid nitrogen out they could take a 3500+ beyond 3.3GHz, but I'm sure those sort of people would have got the fastest FX instead so they could raise the multiplier and not have to worry about bus speeds holding them back.
Myself, I'm sure I'm not alone in holding out for S939 boards with PCI-Express support. And maybe a 90nm Athlon 64 if they arrive before the end of the year. And if the MSI K8N whatever that is available then is as good as the current ones, that'll probably be what I get.

#58 and others -The nForce3-250Gb and NForce3 Ultra do not provide a full integrated Gigabit LAN in the chip. They provide a MAC (Media Access Controller) and a dedicated Gigabit Ethernet PORT on the chip (nF30250GB and nF3-Ultra). This is then interfaced to any number of PHY (Physical Layer) Gigabit Ethernet Controllers.
To quote the nF3 Tech paper from nVidia:
"NVIDIA nForce solutions provide an industry-standard Reduced Gigabit Media Independent Interface (RGMII) for attachment of the 1000BASE-T Gigabit Ethernet PHY. The open, nonproprietary interface lets system designers interface the NVIDIA solution to Ethernet PHY from a variety of vendors. Consumers and enterprises all benefit from a broad range of competitive PHY offerings."
This means seeing a listing of a particlular Gigabit Eternet Controller does NOT mean an nForce3 board is not using the on-chip Ethernet.
If you look closely at the specs for the MSI, the Marvell LAN chip is spec'ed as PHY. It is also worth noting that the Marvell 88E1111 is the same chip nVidia used in their Reference designs for the nF3-250Gb and nF3-Ultra Reference Boards, but other brands can be used as you can see in the nVidia literature.

Wesley,I was wondering how you determined that the MSI K8N Neo2 used the onboard nVIDIA LAN.
If you go to the MSI website and look at the specs for the board, it says that the Dual LAN ports are controlled by Realtek and Marvell controllers, respectively. The nVIDIA LAN is not used.
Is the board you tested different than the board listed on the MSI website?
Also, is there any particular reason that no nForce3 Ultra motherboards use the onboard nVIDIA LAN?

I thought it was pretty widely known that a nVidia graphics card will be totally optimized on a nVidia mobo, so when testing the X800 on an nForce chipset, ull get lower performance numbers wouldnt u, and so wouldnt that muck up the test results?#53, it still does show how well the FX-53 does against a product that is coming out in 2 months doesnt, and this 3.6Ghz is 1.2 Ghz faster and still its being outperformed, so isnt this telling u that the FX-53 is the system to go for? No need to get upset about the intel chip not being out, get the FX-53 now!

has anybody seen A8V revision 2 anywhere?Anemone - Friday, July 23, 2004 - link
ECC while nice, doesn't seem to come in any high performance modules that aren't registered. And we know these boards don't take registered memory, which would make using ECC memory translate to using something at PC3200 or below.Am I incorrect?

I'm pretty new to overclocking. So when you guys say you can bump the fsb to 290 with a lower multiplier and a 1:1 memory ratio, does the memory now have to run at 290 as well, or can it stay at default 200 to keep those tight 2-2-2 memory timings? How exactly does that work?
