5 out of 5 eggsWorks great in 2014

Pros: It's been 5 years since its debut, but this is one reliable and stable board. Still serving in our home theater PC without an issue. It accepts ECC RAM and actually explicitly allow you to configure ECC check rate, unlike other boards with the same chipset.

Cons: While it is not ASUS' fault, it must be said that as with any chipset-based, on-board RAID, it simply does not work like real RAID when it comes to hot spare management, reliable rebuilds, recovering from unexpected errors. I take it that it's there for striping a couple of drives for some additional I/O throughput at the expense of reduced availability (ALL drives must be alive = less reliable than single drive)

For that usage (increased availability), I suggest buying a second hand, real server grade RAID cards off e Bay for next to nothing, which I did. I happen to know what to do with them too from day job, but it should be reasonably easy to figure out for most people who would be reading this review.

5 out of 5 eggs5 Years Running Like a Champ

Pros: Stable, Reliable, Long Lasting

Cons: None really -

Other Thoughts: Asus has yet to fail me - I have had several boards, all still running - Oldest is 12 Years + runs everyday like a champ

I work for a computer shop and we sell 100's of custom built ASUS computers a year - never have had an issue to date for several years running

Pros: had it 2 years no issues

Cons: none that I can think of

Other Thoughts: its built for stability and not speed, I put a 45W processor in there and use it for my always on computer as it uses little to no energy, wish they still made am2 processors but everything is am3 now, so why are you reading this !!!

5 out of 5 eggsAmazing Board

Pros: Low cost, 4 DIMM slots, 8-channel audio, 6 sata ports, PCIe 2.0 x 16 slot, AM2+ w/ support for AM3.
I used this on the first computer I built, and haven't had a single issue. I've upgraded and expanded the computer excessively, and have had no issues. I started with an AM2 chip (6000+) that was really cheap. Less than a month ago, I managed to put in a phenom x6 1090t after a simple BIOS update and it's now screaming...

Cons: Cramped, not enough expansion ports, DISCONTINUED!!

Other Thoughts: I have have overheating problems with my computer, and have had the side of the case off for several months, but I'm using the stock cooler and had a broken PSU fan for a while.

When upgrading the CPU from the 6000+ to the 1090t, I accidentally took out four screws holding the piece of plastic holding the heatsink in place. I had to rebuild the whole computer and have had no loss of functionality even after all the damage that was done (even with my tiny case). I also managed to reattach every single cable with no issues without using the manual. Very good board for all but the most serious gamers, but if you're crazy enough to do SLI or CrossFire, I doubt you'd care about getting a cheap hexacore and would probably go with Intel...

5 out of 5 eggsMy First Build

Pros: This board has all that I needed and more, Though I will have to get an IDE adapter for an old hard drive. Installation was simple by just following the instructions. I used a mid tower case and there's lots of room for airflow and an octopus of power cables.
I love the instant on feature, I am a student and always seem to have a last moment question before I rush to class. It only takes seconds to ask the internet, even when the computer is off.

Cons: The I/O cover is trash, literally.

Other Thoughts: I am adding some other Asus products to my system

2 out of 5 eggsI was mislead

Pros: Cheapest AMD board with PCI-E x16 2.0 for my budget PC build. Asus

Cons: I purchased this motherboard along with 4 x1 gb DDR2 1066 RAM. I was really (insert negative word here) to learn when reading the manual that "Due to AMD limitations the RAM will only run at 800 when installing 4x 1066 sticks for system stability".

Also, when I plugged in my brand new mouse into one of the rear USB ports the plastic piece that's inside the USB port came off and was stuck in my mouse! That port is now useless. That's a first for me!

Other Thoughts: So I paid extra money for the 1066 RAM when I could've bought 800 for cheaper. What a load of (insert negative word here)!! That should be clearly stated on the product description or product specs!

I'm not going to bother RMA'ing it because I don't feel like taking the whole computer apart and I can just use one of the other USB ports.

5 out of 5 eggsStill going strong

Pros: This is a yearly update. I have built 2 HTPC's with this board and both have been totally troublefree. Have been totally happy with how upgrades and different components work with these. Have used several CPU's and memory and all have worked well. One of the systems has been used for trying out the Windows 7 betas and RC versions.

Cons: The one problem was with some high voltage ram that the motherboard would not put enough voltage in. That memory did run fine at lowered speed.

Other Thoughts: Quality motherboard at a great price.

5 out of 5 eggs

Pros: I have this in my custom build that I built back in April '09 and have not had any major issues at all. Everything works and the computer started up the very first time with absolutely no issues.

Cons: Startup is not lightning fast, but I never expected it to be. Its not even worth knocking off an egg off the rating, honestly. It does exactly what I need it to do and I have no complaints to really speak of.

5 out of 5 eggs

Pros: Great overclocking features, inexpensive.
I've had no problems with this motherboard since I got it. The C.P.R (CPU Parameter Recall) has allowed for less worry when overclocking.

Cons: None.

Other Thoughts: If you are not running the latest BIOS, then update it. I gained around 300 points on the 3DMark Vantage. The Asus Update Tool made it easy, no floppy needed.
