The shipping Gigabyte BIOS for the K8NXP-9/K8NXP-SLI family provides a wide and useful range of adjustments for many features, with the notable exception of a very limited range of memory voltage adjustments compared to other boards in the SLI roundup. As is the Gigabyte custom in recent designs, Advanced Chipset Features (and Memory Timings) can only be seen when you hot press CTRL+F1 while in the BIOS. HyperTransport adjustments are also provided in the hidden Advanced Chipset Features menu.
There are no BIOS options for adjusting or controlling SLI. This is handled in the nForce4 platform drivers and the nVidia graphics drivers.
The Gigabyte K8NXP-SLI, like the sister K8NXP-9, was designed as a top-of-the-line nForce4 motherboard. As the flagship model, it sports all the top Gigabyte features.
We are pleased that Gigabyte uses the nF4 on-chip Gigabit LAN by supporting it with a Vitesse (Cicada) Gigabit PHY. Gigabyte then goes one step further by including a second Gigabit LAN on the PCI Express Bus. This second LAN is also removed from the constraints of the slower PCI bus as it resides on the much faster PCIe bus.
Audio is AC '97 2.3, supported by the popular 8-channel Realtek ALC850. The K8NXP-SLI9 includes a wide range of audio I/O provided to make the most of the 850 chip. This includes 6 programmable audio mini-jacks and coax SPDIF in and out - all on the rear panel.
A pioneering feature for Gigabyte has been their support of high-speed 1394B Firewire on their boards. This continues with the K8NXP-SLI with 2 ports capable of 800MB/s or Firewire 800. This is double the speed of 1394A for those looking for fast Firewire access.
From a feature, board layout, and BIOS options point of view, the K8NXP-SLI can be considered the twin of the K8NXP-9. The only real change is the replacement of one PCI slot with a second PCIe video slot. All the good things about the features and layout of the K8NXP-9 are still here in the K8NXP-SLI.

I'm curious, where can I find benchmarks of SiI3114 with a 3 or 4 drive RAID5 setup? Read/write speed, access time, CPU utilization (especially important since it's essentially a software hack), general stability impressions, etc.I'm finally replacing my aging Duron 1200 soon, and looking at A8N-SLI Deluxe (no other NF4 board has a layout suitable for passive/quiet chipset cooling due to video card interference), and I plan to eventually build a ~700GB redundant storage array as home media server on it. However, I can't find benchmarks of SiI3114 RAID5 function anywhere.

About the audio CPU utilization tests. Is that with the nForce Audio or Realtek driver?Wesley Fink - Monday, February 28, 2005 - link
#15,#18 and others - the 3DMark2003 SLI scores were an incorrect duplicate of 3DMark05. The 3DMark03 SLI scores have now been corrected and should make sense now. I apologize for the error.#4 - I saw none of the heat and instability issues with the DFI that were described at [H]. I discussed this with Editors from several other websites who also had no problems with this board. I would agree that the 5V jumper for very high memory voltages can get everything on the board real hot real fast, but this is a feature unique to the DFI and one that only the hardcore with more advanced cooling would attempt to use anyway.
#5,#20 - Any x16 PCIe slot can be used for x1 or x4 or any other flavor of PCIe. MSI does NOT have an extra x1 slot, but they tell us video slot 2 can be used for an x1 device. You still can't use SLI and another PCIe device at the same time on the MSI, but you can use single video with an additional PCIe device in video slot 2.

#4 - Abit has just shipped the Fatal1ty Ultra board to AnandTech. We haven't even received it yet. It will be included in a later Ultra roundup, bu the Ultra boards will have the same performance in single video as the similar SLI board from the same manufacturer. We met with Abit this weekend and they told us it would still be several weeks until their SLI would be available for review - and the SLI is NOT a Fatal!ty board.L3p3rM355i4h - Monday, February 28, 2005 - link

"but on the Asus board you also have to connect another 4-pin Molex for additional video card power. Asus says that this is required for "stable SLI operation", but the other 3 SLI designs do fine and are quite stable without the 5th power connector."The gold-winner DFI also has the same connector, though it wasn't mentioned in the review. And even though it wasn't necessary in your testings (with an OCZ 520W PSU), other people (like tbreak.com) could only find a stable SLI setup with the ASUS board, probably because of it.
I also don't think its location is important, the fact it's close to the PCI-E x16 slots is probably a smart engineering decision.
For future reviews it would be nice if you could show results with "Maximum FSB" where it actually means "Maximum FSB", that is, you remove memory overclocking from the table. It's great to see DDR600 and beyond, but I'm the kind of guy who spends $130 for quality 1GB of RAM, but still want a board that can take a 3000+ to 9*300.
It's not really a 1:1 ratio as you're always using a divider for memory speeds (from the CPU clock).
Looking forward to reviews of the mainstream PCI-E boards (K8T890, nF4 Ultra, etc).

oops typoIt's a shame that there are non nF4 Ultra boards with HD Audio.
I meant

Jeez, Wesley, that must have been a hell of a job. Thanx.It's a shame that there are non nF4 Ultra boards with HD Audio.
#12 Right, I am contemplating the Gigabyte GA-K8NXP-9 (the Ultra, not the SLI) and wonder if the Yesico FL-420ATX will do. Have you searched http://www.msi.com.tw/program/products/mainboard/m... or http://www.giga-byte.com/MotherBoard/Products/Prod... ? Look for manuals (Gigabyte) and compatability tables (MSI).
I wish though these manufacturers would clearly state if its ATX 1.3 or 2.0 etc + minimum V/A requirements. That would be much easier than scrolling through their website.
Just one silly question, because this has not been clear since the introduction of SLI-boards. Can you use a one of the 16xPCI-e slots on a SLI-board for something else than a second graphics card (in the future)? Maybe a (hefty) soundcard in the future?

btw, excellent review, one of the best i've read in a long time!blckgrffn - Monday, February 28, 2005 - link
Yeah, what is with the 3dmark03 scores? The SLI seems really low..more like a repeat of the 05 scores....Glad to see more indepth mobo reviews! I for one was getting tired of looking at the BIOS as a way to differentiate!
