Ethernet Performance
The new motherboard test suite, launched earlier this year, includes LAN performance measurements. The test procedure that we use was first described in a VIA white paper.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 nForce4 Ultra motherboards.
We set up one machine as the server; in this case, an Intel box 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:
Nttcps - m 4,0,On the client side (the motherboard under test), we used the following Command Line:-a 4 - l 256000 - n 30000
Nttcpr - m 4,0,At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.-a 4 - l 256000 - n 30000
CPU utilization measurements for Gigabit Ethernet can be somewhat misleading, since they measure the percentage of CPU tie-up at sustained Gigabit receiving. In reality, it would be very rare that you would actually see sustained Gigabit transmission levels on your PC. For that reason, you should put the measured CPU utilization of Gigabit PCIe LAN in perspective. It will almost always be much lower than what we have measured.

This board sounds fantastic!Hacp - Friday, July 29, 2005 - link
Competative with similar Nforce4 boards(DFI LP) isn't enough. They need to beat the price by 5-10 dollars in order to regain the edge. I agree that the VTT options is awesome (for you BH-5 users), but in order to kill the current proven top Overclockers board, they need to be very competative with the DFI in terms of price.Also, I was wondering if they managed to fix the cold boot issue with these boards. If the cold boot issue is a non issue with these boards, and they are priced exactly the same as the DFI Lan Party boards, then it is a no brainer for BH-5/CH-5/UTT users as to which board to pick (unless they already are doing the 3.3 Rail Vdimm mod).
Also, the 2nd page, He art in the first sentence needs to be fixed, and in the first page, it says AMD in the first paragraph when its supposed to say ATI.

I don't think so, a lot of people complain about problems with the DFI.....and it has a super loud fan on the chipset which is difficult to replace because the video card is right on top of it.I personally would never buy a DFI....different people obviously have different priorities
If this board is rock solid stable like AT reported, then they will have a winner.

looks like a strong competitor, and here was a typo pg. 11"The Sapphire ATI chipset performs at least as fast as the best of nForcee4 chipset boards"

I think that was intentional. They're comparing the ATI to the "NForcee" by MVidia...like you can compare a Seiko watch to a BOLEXRyanVM - Friday, July 29, 2005 - link
In the first pic of the motherboard, it clearly has 8 SATA ports. However, the next page lists the specs with 6 SATA ports and the next picture seems to confirm that. Is there indeed an 8 SATA port version as well?Wesley Fink - Friday, July 29, 2005 - link
The pictures on page 4 were provided by Sapphire and are earlier prototypes. The actual production version we tested is pictured on page 5 and has 6 (not 8) SATA ports. We apologize for the confusion. There are indeed pads for 8 SATA ports on the production board, so there could be further developments.ncage - Friday, July 29, 2005 - link
What i like:Performance in general
good audio quality (im wondering if it supports any of the eax extensions though which would be great if it did. Would elimante the need for a sound card.)
What i don't like:
bad USB2 performance. This would affect me big time. I have a pro consumer camera (8MP Olympus C-8080) and i usually transfer a bunch of images at a time from my camera to my computer so this is definitly a disapointment.
I really like nvidia as a company. Their driver team has from the start been top notch. I think that is one of the things that led to their popularity. I generally have always gone with nvidia except in the 9800 pro days because you know why. I currently own a 6600gt which i love. Anyways the only thing that upset me that nvidia did was to take out soundstorm out of thier chipsets. I hope ATI bringing high end audio will force nvidia to reconsider. Nvidia knew that a lot of customers were asking for soundstorm back yet they still wouldn't put it back in. I just don't understand this.
I hope thier are boards produced that don't have dual video card abilites because of price. I really don't want two video cards. I only occasional play games and im not going to spend 500-900 on two video cards. So we shall see how this plays out.

The mobo manufacturers were griping about the price. Also, I believe the demand was too low. Yes I know lots of geeks liked it but we're a small percentage of the market.BPB - Friday, July 29, 2005 - link
"Today, we look more deeply at production version of the ATI Grouper that will be launched by Sapphire next week."So, when do we actually see these? If it's by end of Summer, great. If not, it may just be too late. I think most people who've waited for ATI to get this out have already gone to nVidia. I know my buddy has.
Also, regarding Crossfire, can an AIW X800XT PCIe work with a plain old X800XT PICe?
