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.

If i was a doubting type I would suggest that Nvidia spent as much time tuning their drivers for benchmarks as they do games.Nice to see support for some unreleased games such as Battlefield 2 on the list though.
Wesley, you get my email btw? (sorry for bugging you)?

I've done some further testing, and still no luck. The PCStats review also indicated 192Khz output, but I can't find that either. I'm still hoping for something, and will let you guys know if anything comes up.Other points:
+ The onboard Creative can attenuate the digital outputs just like a regular live could. Most onboard solutions that i have used could not
- Cannot have Analog and Digital outs enabled at the same time (at least I haven't found that yet). All other onboard solutions that I have tried were able to do this. An example of what I'd like to do (ideally) is have my Zalman Real Surround headphones plugged in to the analog ports, and the z5500's plugged into the digital (coax/optical). When the GF complains, I could turn the z5500's off, and put on the headphones. With creative you do this BUT you also have to uncheck the digital out only box. If they can bot h be enabled at the same time, let me know (Y)
- Either the Z5500's can't accept 96/24 on the optical in, or the creative isn't outputting 96/24 on the optical out.
- Only Coax or Optical work at one time (with the Z5500's)
- DD and DTS passthroughs work with Videolan and DVD's/.ts's.
I'll try this board for a while longer, but if encode will not work, I'll be heading to DFI. It's a bit more expensive, but you get the Lan Tote (woohhoo!) and the extra PCIx slots. Anyone have any comments on DFI's onboard sound?

Thanks giz02. One of these days some manufacturer is going to realize there's demand for this and meet it... I just hope that day comes sooner than later.SLK75 - Tuesday, March 1, 2005 - link
I bought the GA-K8NXP-9 because fo the rave reviews on its OC abilities which Anandtech also proved in their pre-production sample reviewed towards the end of last year...All of a sudden now Gigabyte's production version of the board does not seem to clock high as was expected and proved previously WHYYYY ???? and Anandtech make it really clear to Gigabyte that people went and bought their board not only first its great features but also for its OC capabilities...I hope Gigabyte can address this with a new BIOSgiz02 - Tuesday, March 1, 2005 - link
I feel DUPED by that PCSTATS review. I've asked the reviewer for why he indicated that the board can DICE (either how to do it, or who told him it was possible).The board is .... OK...
I'da rather had the DFI (if DICE is not possible!)

#89 - looks like we'll both still wait for the next SoundStorm. Maybe the next gen of PCI-E sound cards will have DDL?bob661 - Tuesday, March 1, 2005 - link
#89Thanks for the test.
giz02 - Tuesday, March 1, 2005 - link
So far, It's a negative on the DICE :(I have a single coax cable connected from the onboard card to my Z-5500's and they are not recieving Dolby on the speaker tests. Left and Right channels come through but that is is... 96-24 is working as well, but zilch on the 5.1 :(

#87: AMD has NOT made it clear that ECC is an Opteron only feature. Read the document from the link I posted. As for ASUS not supporting ECC, download the manual and look at pages 4-21 and 4-22. In the screenshot for DRAM configuration there is an item for ECC enablement. The ASUS K8N-E deluxe (socket 754) also supports ECC. If you still have doubts that the Athlon 64 supports ECC, go to crucial.com and see what memory is supported by the ASUS K8N-E deluxe and A8N-SLI deluxe. I think that you might be confusing registered memory with ECC. If you write code work with critical data ECC is worth having. I have had bad memory in the past that corrupted data without crashing the machine. Considering misinformation that is sometimes provided by motherboard manufacturers and your obvious confusion about the Athlon 64, I think that ECC deserves some mention by motherboard reviewers. I myself would like to understand why the A8N-SLI apparently supports 4 256MB ECC memory modules but not 2 512MB ECC memory modules (page 2-12 in manual), Wesley?
