Test Setup

 Performance Test Configuration
Processor(s): AMD Athlon 64 4000+ (2.4GHz) Socket 939
RAM: 2 x 512MB OCZ PC3200 Platinum Rev. 2*
(Equivalent to current OCZ OC4800)
Hard Drive(s): Seagate 120GB 7200 RPM SATA (8MB Buffer)
Video AGP & IDE Bus Master Drivers: NVIDIA 6.82 Platform
NVIDIA 6.70/6.66 Platform
ATI Catalyst Platform 5.10
Video Cards: MSI NVIDIA 7800GTX
NVIDIA 6800 Ultra
ATI X850XT Crossfire
Video Drivers: NVIDIA 81.85 Release
ATI Catalyst 5.10
NVIDIA nForce 78.01
Operating System(s): Windows XP Professional SP2
Direct X 9.0c
Motherboards: Asus A8N32-SLI Deluxe
DFI LANParty UT RDX200 (ATI RD480)
ATI Crossfire AMD Reference Board
SiS 756 Reference Board
ASRock 939Dual-SATA2 (ULi M1695/1567)
Sapphire A9RX480 (ATI)
Jetway 939GT4-SLI-G (nForce4)
ULi AP9567A (M1695/M1567)
DFI LANParty nF4 SLI-DR (nForce4)
DFI LANParty UT nF4 Ultra-D (nForce4)
MSI K8N Neo4/SLI Platinum (nForce4)
*Samsung TCCD from OCZ and other Memory manufacturers is currently binned into several speed grades. Our test memory would be equivalent to current OCZ PC4800.

Tests used OCZ PC3200 Platinum Rev. 2 (current equivalent OCZ PC4800) which uses Samsung TCCD chips. All memory ran at 2-2-2-7 timing in all benchmarks.

We tested the Asus A8N32-SLI using both single and SLI MSI NVIDIA 7800GTX with NVIDIA video driver 81.85. Once we discovered the improved performance, we also ran a full retest of graphics and gaming benchmarks on the DFI LANParty nF4 SLI-DR for comparison. Resolutions in standard benchmarks were 1280x1024x32 unless otherwise noted. Some standard tests like 3DMarks and Aquamark set standard tests automatically to 1024x768 to force a consistent comparison. Gaming benchmarks were run at 1600x1200 with 4x Anti-Aliasing and 8x Anisotropic Filtering enabled wherever possible. SLI game benchmarks were also run with 4xAA and 8xAF where possible.

Results for the Asus A8N32-SLI are in red, while results for the retest of the DFI LANParty nF4 SLI-DR are color-coded orange. Results for the other boards are in blue. Other board tests used the 6800 Ultra for testing unless otherwise noted and are included for reference.

We added Quake 4, F.E.A.R., and Splinter Cell - Chaos Theory to game benchmarks in this review. Asus targets the A8N32-SLI at the gamer, and these recent games should provide a better picture of the Asus performance in the latest games. We will be adding Battlefield 2 and Call of Duty 2 benchmarks in future reviews. The benchmarks that we have been testing for these two games are not completely reliable for both single-video and SLI testing, so they were not usable in a review that compares SLI performance. As we find solutions to these issues, we will benchmark with these new games.

    The Techreport writes about overclocking with AMD Cool'n'Quiet here:

    They highlight two important bios options:

    quote:

    You can specify the amount that you want to overvolt the processor as a percentage, and the motherboard will supply that much extra voltage consistently as Cool'n'Quiet slides the CPU voltage up and down through its range of possible values.


    and with regards to memory overclocking:

    quote:

    …because C'n'Q will ramp the processor up to its highest possible multiplier as soon as the system's under load. On my X2 3800+, that would result in a 2.8GHz clock speed and a very nasty crash. The DFI BIOS, however, allows the user to specify a maximum CPU multiplier value for Cool'n'Quiet, neatly solving that problem.


    Does this board have these options in bios?

    As Techreport writes:
    quote:

    I think they should become a practical requirement for an enthusiast motherboard's BIOS.


    I must say I agree.

    Can we get some official info on these questions?
    They're high on my list of features. I was all set to go with the DFI until I saw this review. These features may win me over if the ASUS has them too.
  • Live - Monday, November 7, 2005 - link

    It looks like official reply is not going to happen. does anyone know if the Asus A8N SLI;Delux;Premium has this in later bios? If so I would bet this one has it aswell.
  • Capt Caveman - Monday, November 7, 2005 - link

    The latest bios for the Asus A8N-Sli Premium came out yesterday and no, it does not have this feature so I doubt the A8N32-Sli Deluxe will have this feature. Not very many overclocker's use CNQ, so I don't think there's a huge demand for this feature unfortunately.
  • WobbleWobble - Friday, November 4, 2005 - link

    I wonder if it's better than the DFI because of the PEG mode Asus implements on its motherboards, which overclocks the videocard.
  • Wesley Fink - Friday, November 4, 2005 - link

    And I disabled "PEG link" mode for our review. Asus has settings in PEG for Auto, Normal, Fast, Faster, and Disabled. We set "Disabled" because we know this trick. Asus suggests using "Faster" for review tests. On the positive side you have that additional performance waiting to be tapped.

    We also turn off the overclocks that are enabled when many boards arrive for review. That's the first thing we check.

    Really nice to see such diligence!

    Not by 17%

    Also, if you're running SLI with 2 dual-slot video cards, where are you supposed to put a sound card, or any PCI card? It seems like the only slot available will be, if it's possible at all, the one above the 2nd video card. Not sure how anyone's gonna be able to use any PCI card with SLI.
