CrossFire Xpress 3200: RD580 for AM2

- Motherboards
It will be several weeks until ATI AM2 retail motherboards are available. As a result ATI AM2 testing is confined to the ATI "Sturgeon" reference board. Somebody at ATI Engineering is apparently a fisherman, since all the recent ATI reference boards have carried fish names during development.
Whatever the reasons for ATI's delay in launching chipsets for retail ATI AM2 boards, ATI is not in a very good market position at AM2 launch. With the RD580 arriving months later than expected, at the end of socket 939 development, we really expected RD580 AM2 to be quickly out the gate. Instead NVIDIA has retail AM2 boards available from a host of manufacturers at AM2 launch and ATI is sampling a reference board.
As discussed in past reviews, reference boards are a breed apart. They are designed for manufacturer qualification, and rarely see the light of day in the retail market. The ATI reference boards are a bit different since Sapphire has marketed reference boards under their own brand name in the past. They are expected to do the same with Sturgeon.
Since the ATI CrossFire Xpress 3200 AM2 was designed for qualification, not much time will be spent on layout. Features, other than integrated chipset features, will not be an overriding concern. Additional features can be selected by manufacturers based on their intended market and price point.
Some notes from using the reference board. Loaded with X1900 CrossFire, there are still 2 usable PCIe x1 slots. However, there is no usable PCI slot if CrossFire is installed. Since users who spend over $1000 for video will likely want to use a standalone audio card, this would be a real issue in a retail board. Similarly, with CrossFire installed, the CMOS jumper is hidden under a video card with X1900 XT cards. ATI did users a great service in making dual-channel memory occupy alternate DIMM slots. This provides for much easier cooling of DDR2 DIMMs, which can become very hot when pushing for fastest memory timings.
Basic Features
Reference boards are used mainly for qualification and development by board partners. As a result you will generally see very extensive BIOS options that may or may not appear on retail motherboards. An option of particular interest is the DQS Signal Training option which replaces a wide range of manual DQS skewing options for both memory channels. This worked well in our testing, and made it much simpler to accomodate different memory on this board than the manual skewing controls seen on some other Enthusiast boards.
ATI has aimed their discrete chipset AMD boards squarely at the computer enthusiast. This clearly continues with the CrossFire Xpress 3200 AM2. The range of options and features is the best so far on any ATI motherboard for AMD. This pays off in the tweaking options and performance of the new ATI RD580 AM2.

to quote"short life for AM2 dominance before the launch of Conroe"
Um. Anandtech, if you actually do believe that Conroe's performance numbers are going to hold up in multithreaded applications that exceed 4megabytes of cache data, I think you need to redo you're calculations. After intel's showing of Conroe behind closed doors during E3, I think you should also be aware that the performance numbers are not adding up. Intel might finally be competitive, but even when Intel chips have been competitive in the past, AMD chips have won on price. AM2 may not be the only game in town come this fall, but to say it has a short life? Makes me wonder if you actually bothered even asking the game developers what they are getting out of the processors.

...multithreaded applications that exceed 4megabytes of cache data..."We believe in real world testing. I'm sure there will be applicaitons where AMD still comes out ahead, but synthetic scenarios don't really count. If http://techreport.com/etc/2006q2/woodcrest/index.x...">Intel wins in encoding tests, 3D rendering, gaming, office... and loses in a few specific benchmarks that require lots of memory and low latency RAM access, does it really mean AMD is competitive? I mean, there are still a few specific scenarios where P4 can beat A64, but you don't see us trumpeting those as being representative.
What it comes down to is what most people will get out of each platform, and so far it's looking like a pretty clean sweep for Core Duo 2. Woodcrest vs. Opteron in HPC applications might be a different story (I doubt it), but that's really only relevant if you're running server workloads. As far as pricing, http://images.dailytech.com/nimage/1556_large_conr...">last I saw the $300+ prices of dual core AMD chips are going to have a difficult time competing with $185-$225 Intel chips. Overclocks are also looking promising as well, so a $185 chip running 2.8 GHz will be a force to be reconned with.

can you tell me the what and the when of this amzing revelation?Slaimus - Thursday, June 1, 2006 - link
You can run CrossFire on 975X as well. It should be a competitive platform once the new CPUs come out.

Umm, the article made no mention of the Sil3132 performance on the A8R32-MVP, which I believe is bugged.Trisped - Thursday, June 1, 2006 - link
http://www.anandtech.com/mb/showdoc.aspx?i=2767&am...">http://www.anandtech.com/mb/showdoc.aspx?i=2767&am...First chart, #1 is the Silicon Image 3132 SATA2 (ATI) performance rating.
Axbattler - Thursday, June 1, 2006 - link
I saw that. But if you look at the second graph, the performance of the Sil 3132 in the MSI board is considerably worse than in the ATI reference board.That is still quite usable, but the one from the Asus A8R32-MVP is basically unusable (slower than what modern drives are capable).
Wesley Fink - Thursday, June 1, 2006 - link
We retested Sil3132 on the ATI and some other controllers for this review, and the other 3132 data should have been deleted. Now corrected. We are not aware of the 3132 issue with the A8R32-MVP. The Sil3132 is one of the best SATA2 controllers on the market, and it is a much better performer than the Sil3114.Axbattler - Thursday, June 1, 2006 - link
The result does shown in the review does suggest a solid performance from the Sil3132 controller. However, this is what I have been experiencing:- http://img267.imageshack.us/my.php?image=burst4dh....">http://img267.imageshack.us/my.php?image=burst4dh.... (Sil controller)
- http://img71.imageshack.us/my.php?image=burst27ja....">http://img71.imageshack.us/my.php?image=burst27ja.... (ULi controller)
Two motherboard bioses were tested (0311, 0404), as well as all the drivers from 1.0.9.0 (bundled with the motherboard installation CD, to the latest 1.0.16.0
The poor HDTach performance is reflected in real world application too, gaming loading, file copying are all slowed down to horrendous level.
I believe that Gary was able to replicate this issue (not sure if he eventually found a way around it), although I suppose that based on the result of the other board, it is an issue specific Asus board (perhaps the A8R32-MVP). Is there any chance you could run a test to confirm this?
Very few people in forums that I've visited use the Sil controller, perhaps due to the positioning of the SATA socket (which is actually optimal to where my Raptor is installed: on a 5.25" drive bay).

ATI AM2.jpg is a bit blurry when blown up. You might want to set the camera on the highest quality setting so that doesn’t happen.0X looks like a typo
Why did the Audio Performance charts not have any NVIDIA solutions?
