Basic Features: Asus A8N-VM CSM

With the feature list for the GeForce 6150/nForce 430 chipset, you will get a pretty good idea of the features and capabilities of the Asus A8N-VM CSM. The only significant addition to the feature set is the welcomed addition of Firewire ports with the VIA 6307 chipset.

 Asus A8N-VM CSM

Form Factor Micro ATX
Chipset NVIDIA GeForce6150 Northbridge - NVIDIA nForce 430 MCP Southbridge
Integrated Graphics NVIDIA 6150 GPU
Dual VGA Output: DVI-D and RGB
Maximum Resolution 1920x1440
Note: DVI-D only supports digital output and cannot be converted to output RGB signal to a CRT display
Bus Speeds 200 to 240MHz in 1MHz Increments
PCIe Speeds Fixed
PCI Fixed at 33
Expansion Slots 1 x16 PCIe
1 x1 PCIe
2 PCI
OnBoard GPU Auto, Always Enable
Frame Buffer (UMA) 16M, 32M, 64M, 128M, Disabled (64M Default)
Core Voltage Not Adjustable
CPU Clock Multiplier Not Adjustable
HyperTransport Frequency 1000MHz (1GHz)
Supports AMD Cool'n'Quiet
HyperTransport Multiplier Auto, 1X, 2X, 3X, 4X, 5X
DRAM Voltage Not Adjustable
Memory Slots Four 184-pin DDR DIMM Slots
Dual-Channel Configuration ECC/non ECC
Regular Unbuffered Memory to 4GB Total
Onboard SATA/RAID 2 SATA II Drives by nForce 410 (RAID 0, 1, JBOD)
Onboard IDE/IDE RAID Two Standard ATA133/100/66 (4 drives)
Onboard USB 2.0/IEEE-1394 8 USB 2.0 ports supported by nF430
2 IEEE 1394 by VIA 6307
Onboard LAN Gigabit Ethernet by Marvell 88E1111 PHY
Onboard Audio High Definition ADI Soundmax AD1986A
6-channel, auto jack sensing, SPDIF out
BIOS AMI 0506 (11/18/2005)

This is also the first NVIDIA chipset board that we have tested to support High Definition Azalia audio. Asus has used the same ADI AD1986A chipset used on the recently reviewed Asus A8R-MVP motherboard. However, the SPDIF connection is only provided by an optional bracket. TV out is another feature that requires an optional bracket. Since HTPC/Multimedia buyers will be looking for these features, the optional brackets will be a huge disappointment for many buyers.

As is the norm in Integrated Graphics boards, the Asus A8N-VM CSM is micro ATX. There is still an x16 PCIe slot for a graphics card should you choose to upgrade in the future, along with 2 PCI slots and an x1 PCIe slot. Since so much is integrated into the motherboard, there isn't as much concern about layout as there would be in a full-size board. Almost all micro boards require some layout compromises, and the larger question is whether cable connections and IO make sense.

Asus does a great job with placement of power connectors. Even on this micro ATX board, the 24-pin ATX and 4-pin 12V are both near board edges where they work best. Both single and dual-core Socket 939 AMD processors work well on the Asus.

The nForce 430 Southbridge did not have any cooling, but it does get quite warm during operation. It is interesting that NVIDIA has another name for the 430 - the MCP51. As we typically see with recent Asus designs, cooling is completely passive with no active fans.

    Speak for yourself.

    What are the chances that this is not Asus' HTPC motherboard?

    Could they be developing another model for a home theater PC? -- If so, will it use the nVidia chipset?

    As much as I want to use this board for my HTPC, I have to examine why Asus would not have - at the very minimum, included a spidif cable and TV out cable.

    Something just doesn't fit in this picture.

    I would like to have game performance compared to a single channel board using one of the current integrated graphic chipsets - there is a Biostar board for Socket 754 and a Asrock one. Or at least to have performance checked with a single DIMM (or two DIMMs in single channel mode)
    Thanks

    Poor implementation of a good idea by Asus.This chipset screams htpc, why have HD audio without out of the box spdif? Might as well have realtek audio. The S video out should also be standard with an optional component out dongle for those who need it. Add-on brackets take up pci openings on the case, quite a few htpc cases are microatx where these slots are a premium.

    aw man.... if only this board can OC...

    According to the picture of the motherboad the board you tested was 1.01.

    However, I just read that there is a 2.0 rev board. Are you aware of this? Do you know if this is accurate?

    I can't find anything about this on the Asus site and would like to know about this before I get the final piece (motherboard/video) for my HTPC upgrade.

    Thanks for the quick review, and I too would like to know more about it's CPU utilization during DVD and HDTV playback.

    Again, thank you.

    PS. and if I missed it, what was the BIOS revision you used for your tests.

    may we see HL2 and MPEG2/WMV9 decoding benchmarks, please, Anand? also, how does one go about purchasing the addon card, and is it S-Video only, or is there hope for component out?
  • BigLan - Thursday, December 1, 2005 - link

    Does the nvidia firewall actually work on this board, or does it corrupt zip archives as have been reported with the nforce4?
  • Leper Messiah - Thursday, December 1, 2005 - link

    Performance is mediocore, features missing, can't OC. Guess I'll be sticking with a biostar 6100-T for my next F@H box.
