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".

"So, is SLI worth the cost and the effort? For some, the answer will be a definite no. The SLI boards still cost a great deal, setting up the system is still a daunting task, and the cost of two top-of-the-line video cards will be just too much for many to consider SLI to be a real option."I still do not understand why this argument is so popular. Why is the general assumption that purchasers of SLI capable boards will immediately want to jump into a dual-card config? The idea is flexibility. Sure, 2 6800's are expensive now, but they will inevitably get cheaper. So why not buy one now and then profit form your forward thinking later down the line when the price of a second card is cut in half and there are more SLI-supported games available. I concede that the mobos are 50$ more than a non-SLI board but, for 50$, I'll take the enhanced upgrade path. Out of the gate the SLI boards are the fastest single or double-card NF4 mobos available, so whats to lose?

Wesley, well done, although I have to admit I skipped over some of the pages describing the individual boards as I am not personnaly intrested in buying a SLI system.One thing about the bar graphs, it could have been a little easier to compare between a single card and SLI if you had used split bars like in this graph
http://images.anandtech.com/reviews/video/ATI/rade...
using the top half of the bar for single card and the bottom for duel cards.
It would also be nice to see a comparasion of disk controller, firewire and USB performance (and anything else that is chipset specific) using all the different brand chipsets.
I don't think you are the person that does power supply reviews, but with all the concerns recenty about power supplies it would also be nice to see an article that not only describes some of the differences in power supplies but what components draw power from what rails and how much they draw (I have seen power supply guides that give an idea of how many total watts is needed but very little information on how those watts are divided up between rails).
One last thing, I have a little problem with this statement "the ability of a motherboard to run at much higher than stock speeds tells you something about the quality of components used in a motherboard". If every motherboad had a perfect BIOS and they all had the same overclocking options then your statement could be true, but that is not the case. Would you call all Intel branded motherboards poor quality just because Intel doesn't put overclocking options in their motherboards BIOS? What if an OEM decided to use one of these great overclocking boards in a prebuilt system and the only change they made to the board was to eliminate the overclocking options from the BIOS, is that board now poor quality?

Well well well, seems you are right. The MSI nForce 4 Ultra board in Australia even has 1x PCI Express slot...http://www.msi.com.tw/program/products/mainboard/m...
Does anyone know which boards support Firewire 800 (1934b)?
Also to Wesley, thanks for the reply, do you have a rough idea when the nForce 4 Ultra comparison would be available?

There seems to be different version of MSI's SLI boards depending on where you live. In Australia the SLI board is a MSI K8N Diamond. The interesting thing about this board is that it has two PCI Express x1 slots. as well as the two x16 slots for SLI. It also has a wlan option.falcc - Monday, February 28, 2005 - link

#43, I'm aware it needs a PHY, but I always thought it worked the same way as it did since the nForce3-250Gb, with no PCI-E involved.I checked out the manual for the MSI K8N Diamond and ASUS A8N-SLI, from them:
MSI
"Dual LAN
? Supports dual LAN jacks
- 1st LAN supports 10/100/1000 Fast Ethernet by nForce4 SLI
- 2nd PCI Express LAN supports 10/100/1000 Fast Ethernet by Marvell 88E8053"
ASUS
"nForce4 built-in Gbit MAC with external Marvell PHY :
- NV ActiveArmor
- NV Firewall
- AI NET2"
I couldn't find a reference that the chipset LAN is tied to PCI-E.

Excellent, thanks Wesley. Every response I've had from now has been, quote:"With regards to the overclockability, it has AI Overclock, PEG link, and other options, the extent of the overclockability was not promised and unfortunately some customers expect amazing overclocking abilities when the 1T overclock is still a good feature and is overclocking in action."
Perhaps what you would expect them to say when their board clocks more than 60mhz lower than some competitors.
If you could keep me apprised of their response either here or at amiles(at)gmail.com that'd be great. Thanks again.

I really wish MSI could pump a bit more voltage for the ram, 2.85 is a bit low, especially considering the Asus is giving 3V and DFI is giving 4V!! Guess if u want to run your good old BH5 sticks at 250mhz 2-2-2-7, DFI will be the way to go. But I really liked the MSI mobo. o well, guess u can't have everything.JoKeRr - Monday, February 28, 2005 - link

#6 & #56 - I saw the same behavior with the A8N-SLI Deluxe during our testing, and I shared my results with Asus. I forwarded your comments and my own to the Asus A8N-SLI BIOS and Engineering team.
