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
CPU Interface Socket 939 Athlon 64

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.

    It appears this type of board is mostly touted for HTPC use, but I think it's quite excellent for a capable office system as well because of the DVI connector, dual-head capability and gigabit LAN - and of course all the other connectivity goodness that's largely standard these days. And passive cooling, which I appreciate.

    I'm not aware of the existence of any other board with integrated graphics that has a DVI connector and can drive 2 monitors without additional expense. This is absolutely great for a very productive office setup without really breaking the bank (although using a cheaper Sempron CPU is out, since it's Socket 939).

    Of course, competing boards should follow based on this chipset, which is only going to be a good thing. (Are all GeForce 6150 boards expected to have DVI connectors?)

    By the way, are there some availability issues with this board? Newegg.com has had it listed out of stock for a good while now, periodically pushing back the ETA (which now isn't even mentioned anymore). Not many retailers seem to carry it yet, judging from the RTPE.

    The only issue with this is that you can't use one of those DVI to VGA converters on this board. There are several warnings on the website and in the manual not to do that.

    There are many (cheaper, it's true) LCD panels that support VGA in, so this won't be such a big problem. Sad is that - if you want dual out, you need a panel with DVI input.

    Indeed, but for office applications - especially for those that care enough to invest in a dual head setup - LCD panels are generally more desirable I would think. I know it's what I want for my work system.

    The article has been removed?? Product Disclosure Statement?
  • ksherman - Thursday, December 1, 2005 - link

    called an NDA (non-Disclosure Agreement) ;)

    lol, it is too, right term wasn't coming to mind :)

    The article got pushed back by a day to accommodate the Yonah exclusive yesterday. That's why it was temporarily removed.

    Take care,

    Thanks for the reply Anand, it's nice to have a site where we can still get reasons for things :)

    It would have been nice if Asus included High Definition Audio on this board.
