As Asus has most often been the performance leader for boards for Intel processors, MSI has been the leader of late in the performance of their Athlon 64 motherboards. The whole K8N series from Socket 754 through Socket 939 has provided some of the best performance available for Athlon 64, and provided several Editors Choices along the way. Past performance has set high expectations as we took a closer look at the nForce4 Neo4/SLI.
MSI is the only SLI board in the roundup to provide a SATA 2 add-on controller instead of the SATA 1 Sil3114 used on all the other SLI boards. The Sil 3132 only supports 2 additional ports (added to the 4 SATA 2 provided by nForce 4), but the 2 ports are 3Gb/sec. All of the SLI boards provide dual Gigabit LAN, but MSI provides two PCIe LAN ports, assuring top performance whichever port you use. The biggest standout here was MSI's decision to use the Creative SoundBlaster Live! 24-bit audio chip on the K8N Neo4/SLI instead of the cheaper codec that others used. MSI claims that the Creative chip is a hardware audio solution, and not just a CPU-hogging software solution such as you would normally see on motherboards. Our CPU utilization tests support MSI's claims with very low CPU overhead. The Audio also fully supports Dolby Digital encoding, which will matter a great deal to some users.
Except for the missing PCIe ports, layout of the MSI is really excellent. Ports and power connectors are where they should be, and even the floppy port, which many no longer use, is in a location where full tower owners can use a regular floppy cable for their connection.
Our only complaint is the finicky and flimsy lock for the SLI card. We doubt that the lock will last through many changes from normal to SLI and back. In addition, once the pin is turned to unlock the SLI selection card, it is extremely difficult to lock the SLI card again once you have switched the mode. Someone in MSI design needs to take a look at this little plastic part and improve it before MSI gets a raft of RMAs because users can't secure the SLI card with a broken "lock pin".

And then he double posts and can't spell "graphs." (not "graphes!") *bangs head on wall* Oh well. To err is human. Happy Monday! :)Wesley Fink - Monday, February 28, 2005 - link
#33 - That is correct, but to implement PCIe Ethernet the mfg must use a PHY gigabit ethernet controller. In fact, as I state in the review, all 4 SLI boards implement PCIe on Gigabit #1, but all 4 boards have dual gigabit ethernet. Most implement PCI on Gigabit #2 with the results you can see in the ethernet performance charts.#30 - It IS a significant point and I thought we were clear that the 3132 is PCIe. I will add that to the chart to removee any confusion. However, there is another side to MSI using PCIe on all the on-board features. With both PCIe LAN's and PCIe SATA2 add-on there are no channels left from the 20 lanes available for PCIe slots.

Minor typo: HL2 resolutions on the graphes are listed as 16,000 x 1200 instead of 1600 x 1200. Either that or you're using a seriously wide screen! ;)mechBgon - Monday, February 28, 2005 - link
Wes, an academic point: unless something's changed with nVidia southbridges, the nForce3/4 gigabit Ethernet controller isn't a PCI-based device, it's native to the southbridge and rides the Hypertransport bus. If you're getting >900Mbit/sec in your test, it's pretty obvious it's not on a 32-bit PCI bus ;)AlanStephens - Monday, February 28, 2005 - link
#28 - I know for a fact that Creative doesn't support Dolby Digital Encoding. I wish they did though. Here is a quote from Creative's Knowledge Basse on this:"Computer games written with support for 3D audio do not require a Dolby Digital Interactive Content Encoder (DICE) to output multichannel sound, with no exceptions. Sound devices that support the real time encoder technology from Dolby will simply receive the multichannel wave file output and encode it in real time to a somewhat modified Dolby Digital bitstream. Creative does not support the Dolby Digital Interactive Content Encoder on any of its sound cards.
The only difference between a Sound Blaster card and an audio card that has a real time encoder, is that you can make a one-wire, digital connection from your audio card to your home theater receiver and enjoy discrete multichannel sound from the game. However there will be a continuous, slight delay, known as "latency", as the encoder is creating and transmitting the bitstream, and of course the compression scheme being used is "lossy" (i.e. not bit-accurate).
If you want to enjoy 3D audio in 3D enabled PC games in multichannel surround sound with a Sound Blaster card, it is recommended that you connect the analog outputs of the sound card directly to the analog inputs of the receiver."

I wanna know the answer to #28's question. I've been looking for the next Soundstorm... ie I want to output a dolby digital 5.1 (or better) signal through a spdif connection from a non-pre-encoded source, like only Soundstorm can.Can the MSI do this now too??

Why didn't you guys bother to note that the Si3132 SATA controller is PCIe? I think that's a fairly significant point in comparison to the PCI Si3114 controller and it likely explains why the Si3132 was faster.Lakku - Monday, February 28, 2005 - link
I wish you would have discussed 6600GTs in more detail. I am perturbed at a number of sites saying the 6600GT is not worth it for SLI. Specifically from X-Bit (though many have echoed it) "We guess it is the 6600GT SLI configuration that's not very appropriate". The only fact for this statement is the lack of a 256MB 6600GT card. This means its high resolution on some games and FSAA capabilites are limited. But so what? Noone has discussed REAL WORLD prices of 6800GT and Ultra cards. They range from 430 to 800 dollars, for ONE card. Yet sites claim it's better to just get a 6800GT rather then two 6600GTs. I picked up my 6600GT for 170 bucks, brand new retail. It overclocked to 550/1100 easily and I kept it at that, even though it went quite a bit higher with air cooling. I put that in because it gave me another 5%-10% or so increase over stock speed. I could get two for just over 350, almost $100 cheaper, and in a majority of tests, it equals or BEATS a 6800GT. It only suffers when you get to 1600x1200 with FSAA, as its smaller frame buffer and 128-bit interface is a hinderance. But for such a HUGE price difference, is it not worth it? If I had bought two outright (my plan was to get a start on a PCIe based system to bring me up to date for the future, and then buy the next generation cards for SLI), I could use that extra 100 for the GF7600GT (I am assuming this name, and the fact that if the next generations are 24 pipes, then the mainstream will be 12) that when SLId, will be up there in terms of todays speed on 700 to 1000 dollar video combinations, all for under 400. The point is that I wish someone would actually take an IT type approach to this situation instead of badmouthing SLI or the price for running an SLI setup. You get SLI now, be cost effective and get 6600GTs, and you have a great platform for the next generation (if it still exists, but nVidia seems to have put its eggs in this basket so I assume it will be around for awhile) of cards that you can SLI and get great performance. Is SLI worth it? I say the answer SHOULD be a resounding yes if the same performance holds true for the future. It means you can always get two mainstream cards to equal ONE high end card, for a much cheaper price.chup - Monday, February 28, 2005 - link
Is the SB Live! 24 really capable of encoding audio stream into Dolby Digital stream?
