None over other P35 boards really.
IDE placement
Sound no longer works
Same with intergraded NIC
I have a problem with visual lag. All evidence points to this board.
I've given this 4 stars cause it's gotten me through. I should have picked Gigabyte though. I've had some shorting problems with this board, didn't think to RMA it. Both sound and ethernet is completely dead. If I were you I wouldn't even think about this board. Go for a newer P45 board from Gigabyte.

Excellent all around motherboard. Good features for an entry level overclocker.
Not SLI compatible.
Another quality Asus product. Motherboard is an excellent starting point for an entry level system, when tons of overhead to upgrading and basic overclocking. Very stable for every day use, and would recommend it to anyone!

Experience: 11 Days

Good price
Good OC potential
Bad placement of IDE connector (at the bottom, 7 O clock position)
The motherboard worked perfectly with my Core 2 duo E8400 and 2x2gb of corsair ram. The layout of the board did not block my asus 9600GT silent video card, and my Xigmatek HDT-S1283 heatsink fitted also.

The only complaint I have is about the poor placement of the IDE connector on the board, it is located on the bottom left. Meaning that I have to stretch the IDE ribbon all the way up to my dvd burner (be careful it might get in the way of your video card and other PCI cards).

Also if you plan to have 2 video card, go with ATI crossfire on this board because p35 boards do not support nvidia dual SLI.

All in all an excellent product.

solid capacitors
oc's fairly well
45nm support
not very strong at overclocking
i've had this board for a little over 1 month and haven't had any problems with it. It is satisfactory but nothing special, all those crap ocing features are, well, crap lol. If i had to buy again i wouldn't.

Best bang for the buck. Very stable.
Bit outdated for modern days but at this price, it's no brainer to get this mobo if you are tight on budget.
I bought this mobo for Q6600 and it works superbly well. Very stable and handles my 4850 really good as well. Recommended to anyone who are tight on budget but need a good gaming computer for a while.

- Price
- Quality build
- crossfire support
- have not found any yet..
This Motherboard worked well out of the box. It filled all my needs. Firewire is nice, so is 2 pci-e16 slots for crossfire. Support for newer cpus... Asus makes some good stuff!

Experience: 30 Days

Cheap, does the job, NB heatsink
Not the best overclocker, not doing the advertised 1066 RAM speeds very well
This board couldn't do DDR2-1000 with my G.Skill ram which is rated at that speed. The 4pin power connector is located all the way on the other side of the 24pin connector and in such a place that it was a pain in the ass to plug in/remove with a thermalright xp-120 (would be even worse with a TRUE)

Experience: 2 Weeks
Top quality components, great memmory speed, good OC
Design is awkward, the controller interface design is really poor in sata
The board is top quality and the memmory speed is great, very good for overclocking.

But the design of the board is plain bad. The 4 sata slots on the ICH9 controller don't have raid, ahci is not available for later bios versions, they are bootable but vista won't install on them. To install you have to use the connection from the JMicron controller, it also support raid and ahci, but it has 1 sata, 1 E-sata(in the back), 1 IDE, which makes the raid array totally impractical, I don't see the use of having raid across different interfaces. Also the internal sata port on this controller is in front of the pci-e 16x slot, so if you have a big graphic card, it'll be hard to access, and using the right angle sata cable makes the cable go upward, which is even worse with some graphic cards.

Experience: 6 Months
I did overclock my Q6600 from 2,4ghz at 3,2 ghz!
The temperature from the chipset is 49 degrees!
I have this motherboard from 6 months and is working real good!I have the Q6600 and with Zalman 9700 I overclockated the cpu at 3,2ghz!I have 2 gb of ram and a video card ati radeon 2900 pro!It's a good motherboard!It deservs the money!

Experience: 7 Days

Lots of connectivity options, easy overclocking settings, and overall a very adequate board.
e-sata connector on motherboard doesn't work for me, temp. sensor for chipset is near ram so is always hot (45+ celsius for me, ambient room temp 20).
Very happy overall, but I wish the e-sata connector worked properly. I have a PCI-slot port with an e-sata connector that works just fine, so why the onboard one doesn't work, I can't be sure. It doesn't even look quite the same either, but the cable definitely fits in there, it just doesn't recognize my drive.

Running this board with 8 GB of Mushkin DDR2-800, overclocked to 936, and an E3110 running at 390x9, and everything is extremely stable. :)
