Ethernet Performance
The current motherboard test suite includes LAN performance measurements. All of these boards utilize PCI Express controllers with the only difference being the supplier of the core logic.
The Windows 2000 Driver Development Kit (DDK) includes a useful LAN testing utility called NTttcp. We used the NTttcp tool to test Ethernet throughput and the CPU utilization of the various Ethernet Controllers used on the Intel motherboards.
We set up one machine as the server; in this test, an Intel system with an Intel CSA Gigabit LAN connection. Intel CSA has a reputation for providing fast throughput and this seemed to be a reasonable choice to serve our Gigabit LAN clients.
At the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:
All standard Ethernet tests were performed with standard frames and the NVIDIA Active Armor suite disabled unless otherwise noted. Gigabit Ethernet supports Jumbo frames as well and provides a further reduction in CPU overhead.

I really liked it you did a test with BH5 at 1T 2225 timings,BUT,
I would be so much happier if you also could test at how high clocks you
can run at 1T 2225-timings. That is at least how I define overclocking memory.
You still have the board, so pleeeaaaaaaaaaaase give it a try!
You overclocked with 1T 2.5-5-5-7 timings, but as I´m sure you know it´s not the same thing as overclocking the memory with 1T-2-2-2-5 timings, which BH5/UTT owners mainly gain performance from.
This is something I miss with most of your reviews, and I think Many Many readers would appreciate if you both tryed overclocking with tight resp. lose timings in the future.
It´s often tight timings that makes the boards stand out from the rest.
CPU stability and overclocking seldom differs more than 10% while the RAM clocks at 1T-2-2-2-5 often is either 200MHz or something like 280MHz (40%). Many boards still can´t run 1T-2-2-2-5 at all.
Memory Performance is about 1. tight timings and 2. high clocks
Maybe my facts isn´t totally correct, but I hope you see what I´m aiming at :-)

Hi,
We are currently testing another RD480 board so I will provide the highest stable overclock at 2-2-2-5(7)-1T for the Abit and Asus RD480 boards along with the new one.

Great! Splendido! Magnifico! eeeeh, Excellent! Much appreciated!Duplex - Wednesday, April 5, 2006 - link
How are things going with the revised 1.1 bios, is the 256HTT limit gone?Has there been any time to look into it? ;-)
I read the ECS-review. Nice to see the
"The ECS KA1 MVP was very stable with 2 DDR modules in Dual-Channel mode at the settings of 2-2-2-5 at 2.7v. We were able to operate the memory at this configuration up to a 226HTT x12 setting." !!
Whats happening with the tests you mentioned above with the Asus and Abit board?
Estimated publishing date?

Agreed, love the look of this MB for it's passive cooling and fan control options. I'll have to wait for the AT8 32X though as the AT8 is now discontinued here.Any news on the BIOS #1.1 results?

So far so good. We are waiting on a particular GSkill module to arrive to complete testing.

Dolby Digital Live is an option that a vendor must persue with Dolby and get their motherboard certified. Abit has not shown interest in this before, nothing I can find at the Abit site says this is Dolby Digital Live enabled. You guys sure about the AT8 having DDL?Gary Key - Saturday, March 11, 2006 - link
http://www.abit.com.tw/page/en/motherboard/motherb...">AT8 SpecsThe audio specifications are listed on the global site. The US site has the AL8 specs on the webpage and Abit has been notified of this. Abit is now including the ALC-882D with the DDL option on their higher end boards. We did not see it as being offered originally on the AT8-32x (complained about it) but have been told it will be included now. In fact, their Global website has been updated and shows it on the board. The board I tested had the ALC-882D codec and DDL (5.1, optical out to supporting receiver) was enabled in the drivers I used.

Looks like Abit, even though late to market, didn't bother testing their ATI chipset mobo before shipping it either. They must have figured if Asus could sell the completely junk A8R-MVP garbage, then there were plenty of fools who would rush out and buy the Abit version of garbage. You got to believe that judgment day isn't too far off for the Asian mobo companies if they keep shipping this kind of junk.It's pretty obvious Asus needs to switch product lines from PC hardware to rice cakes or chop suey so their skill set matches their products.

Looks like the paid nVidia forum posters are at it again. They must really be afraid of ATI chipsets to go to these extremes. Wonder why?It's a shame this decent review got hijacked by a few crazies whose only goal was to disrupt and discredit.
