ASUS KCMA-D8 ATX Server Motherboard
 
Most Versatile Dual AMD Opteron 4300 / 4200 / 4100 Serverboard

The ASUS KCMA-D8 server motherboard is a feature-rich yet affordable choice for customers, based on cost effective dual AMD Opteron 4300/4200/4100 series processors, featuring an AMD SR5670/SP5100 chipset, dual-channel DDR3 per processor, high power efficiency, ASUS' unique Proprietary I/O Kit Expansion (PIKE) SAS2 upgrade kit, and ASMB4-iKVM module for remote management, making it an ideal foundation for versatile AMD C32 solution.


ASUS P8B-X
12" x 10" ATX Form Factor and 24+8 Pin Power Connector

The ASUS KCMA-D8 serverboard allows users to build a cost-effective and competitive server with more choices. The serverboard follows standard ATX mounting-hole locations, so users can choose either a desktop PC ATX chassis, which is cost-effective and readily available, or server chassis, which offers a rack and tower chassis that can be fitted to a cabinet for enterprise usage. Furthermore, the 24 + 8 pin power connector supports both ATX (for desktop PC use) and SSI (for server use) power supplies, with the former reducing total cost, and the latter offering advanced server features.

4 out of 5 eggsTerrible PCIE Slot Information for Crossfire Setup

Pros: This MOBO is a workhorse. With the drop in AMD C32 chips prices, building an affordable workstation is very doable.

Cons: ZIP,ZERO,ZILCH information from ASUS on how to configure PCIE slots, so no Crossfire yet.
Pike raid is problematic.

Other Thoughts: Handles SSD drives, Handles BluRay Burners, Handles SoundBlasters, Handles SCSI cards

1 out of 5 eggsRAM modules failed CPU memory test

Pros: Purchased 3 boards in 2011 to build 2 servers, one as a backup. The 3rd board was bought as extra insurance.
The board in the main server has worked well so far.

Cons: One week ago, the power supply for the backup server was dead. When a new PSU was installed, BIOS kept complaining some dimm modules failed CPU memory tests. After trying all different combinations, BIOS finally accepted five 16GB ram sticks out of eight. Even worse, these five RAM sticks only provided 64GB usable space instead of expected 80GB. The 3rd unused board accepted even fewer RAM sticks.

Other Thoughts: The 2nd board was a replaced one from ASUS in 2011 because of the same issue of some RAM slots failed CPU memory test. That was why I bought the 3rd one as additional precaution. Connection between CPUs and RAMs is the most crucial aspect in a motherboard and should be made robust and error free even for low end server board like KCMA-D8. ASUS failed this and was a huge disappointment.

Manufacturer Response:

Dear Valued Customer,

I apologize for the inconvenience this may have caused you. Assuming all the RAM sticks are all known good components, the defective power supply that was replaced might have cause some damage to the components on the motherboard due to unclean and unregulated power going into the motherboard and is causing CPU memory test failure on the RAM modules. I may suggest that you send the motherboard for further testing, assuming the replacement power supply unit is a known good hardware. If you need further assistance sending it in, please email me at cl-rodel@asus.com and write down service# N150441455 on the subject line.

Thank you for choosing an ASUS product.

Regards,

Rodel

5 out of 5 eggsGood home server mobo

Pros: Lots of great features packaged into one server-class motherboard.

Cons: The iKVM module for this board (ASMB4) is sold out everywhere I tried to find one. Also the PIKE RAID cards are a little hard to come by.

The chipset gets very hot and the cheap tower case I am using doesn't offer enough airflow over it. I had to mount a dedicated fan to keep it cool.

Other Thoughts: Using this to run OpenStack for visualization and a FreeNAS instance to provide a home file server. Using the ASUS PIKE 2008/IMR RAID controller.

5 out of 5 eggsWow.

Pros: Tried this after getting a SUPERMICRO MBD-H8DCL-6F-O that was was dead on arrival. ASUS continues to never let me down after years of quality motherboards.

Quality build. Worked with two AMD Opteron 4386 8 core CPU's out of the box. Has no problem using all of the CORSAIR XMS 64GB (8x8 GB) memory I installed in it running at 1333.

This was used for a workstation build. With two 4386's and 64GB of memory, it just blows me away as far as performance is concerned.

Cons: The motherboards are hard to get every now and then? Other than that. None.

Other Thoughts: I've only used this board for workstation builds. But for a workstation, this is a great base to build on.

4 out of 5 eggs2yr review

Pros: Plenty of expansion options, running a home server dual AMD 4130's 2.6GHz, 16GB ram, 8 HDD. Still running strong. Windows 8.1 and several Hyper-V machines, in process of migrating to Server 2012 with Hyper-V's for better network control

Cons: Unable to update the bios error for the ps/2 (which has not worked since purchase). Wanted to use an old ergonomic ps/2 keyboard when purchased. Not the worst issue. Also unable to have the motherboard raid configured, system would not boot up. Instead, used separate Rosewill PCI raid controller.

Other Thoughts: Recommended. Why use for home and have all this server power,.....why not. More or less

5 out of 5 eggsAn Update After 2+ Years of Ownership

Pros: Crossfire support! - For those who have been wondering, yes crossfire indeed works! Crossfire does not work under a server OS, however.

Stable, when using Windows 7/Server 2008 R2 or earlier, this thing is rock solid. Windows 8 has a few issues, but nothing that can't be dealt with.

TRIM works with SSDs in RAID 1 with the Promise ROMB. It probably works with RAID 0 too. TRIM also works with the Pike cards.

Cons: The built in RAID, when configured in a RAID 5, does not get along with Windows 8+. Windows has issues detecting the array even after the Promise drivers are loaded. Other RAID levels work fine.

Further more, the ASUS Pike 2008/IMR, when configured in a RAID 5 under Windows 8, does not work either. At least on this motherboard.

The Pike 2008 and Promise RAID cannot be enabled at the same time. You have to choose one or the other, and if you want all 14 drives, you have to place the Promise RAID into AHCI mode. I mainly use the Pike with just a Blu-Ray and DVD drive connected to AHCI.

Has some ACPI related issues that can result in a BSOD in Windows 8+. If you prevent Windows from sleeping, you won't get any crashes.

Other Thoughts: My setup has grown quite a bit since I first built this PC:
Initial:
AMD Opteron 4180 Processor
Noctua NH-U9D0 CPU cooler
2X 300 GB WD Velociraptor RAID 1
2X 1 TB Seagate RAID 1
2x KVR1333D3LQ8R9S/8GEC 8GB RAM (16GB)
NVIDIA GTX 260
850W Coolermaster PSU
Windows 7 Professional x64

Current:
2x AMD Opteron 4340 Processor
2x Noctua NH-U9D0 CPU cooler
2x Samsung 840 Series 120GB RAID 1
6x WD 1TB Black RAID 10
ASUS Pike 2008/IMR
8x KVR1333D3LQ8R9S/8GEC 8GB RAM (64GB)
2x AMD R9 290x
1200W Corsair PSU
Windows 8.1 Pro x64

Make sure you get a case that has good cable management. You will end up with SATA spaghetti if your cable management is poor.

If you purchase the CPU cooler I have, you will need to move the fans slightly up the side of the heatsink and attach them. If you put them in their proper spots, they will touch the RAM.

If you decide to install a pair of video cards, they will be almost touching. Keep this in mind if you do not buy a card with a reference cooler.

Don't be surprised when you start your new rig up for the first time, if it just sits at a black screen for a bit. It takes a little while for it to start POSTing. If you let this motherboard do a full POST, it takes forever. It's a server board though.

I have had very few issues outside of my own creation with this motherboard, and still highly recommend it.

5 out of 5 eggsGreat value

Pros: Had VMware ESXi 5 up and running within an hour. Dual Opteron 4334, with 2x samsung registered 16g dimms, booting off USB. Works like a charm, didn't have to flash BIOS for the 4334's. Anything that ships past Oct-2011 per ASUS should be a new enough build to support 4200+ Opterons. If it has the 2001 BIOS it will support 4200 and 4300 CPUs out of the box. The 4334 (hex-core) was a steal for $200 apiece (put $30 coolers on each one). Very cost efficient.

Cons: haven't found any so more. For a budget performance server, it is running great. No issues

3 out of 5 eggsDoesn't work with Opteron 43xx Procs out of the box

Pros: It's Asus, and I've had great luck with them in the past. Apparently the newer Opterons are supported if you flash the BIOS.

Cons: Need older Opteron to flash the BIOS.

Other Thoughts: Newegg was great about accepting the return on these. For those of you looking to buy one, ensure that you have a processor that is supported on the older version of the BIOS.

1 out of 5 eggsTHE WORST SUPPORT IVE EVER ENCOPUNTERED!

Pros: LOL!

Cons: We purchased 6 of these boards, 2 of which have gone bad. 6 weeks, these idi*ts still have not been able to get my RMA processed. 18 years in IT, I have never seen such inept support. Give them a shot, you'll see!
