Boasting the new AMD AM3 socket, the Asus M4A78 allows you to elevate your rig beyond the standard limits with support for the next-generation 45nm AMD Phenom II processors. The board is able to reach memory speeds up to 1066 MHz for blazing fast memory access for today’s latest applications and games. A pair of PCI-Express 2.0 x16 cards can be mounted for cutting-edge graphic power with support for CrossFireX.

Besides the 2 PCI-Express 2.0 x16 lanes for the CrossFireX video, there is also a PCI-Express x1 and 3 PCI slots providing the flexibility for further system enhancements. Storage won't be a problem with 1-PATA connector plus 5-SATA connectors. Asus Turbo Key transforms the PC power button into a physical overclocking button.

Has lasted way longer than I thought it would 12/22/2017 11:07:54 PM

Pros: Has more than enough USB ports.
Has IDE support for hard drive, CD drive, and floppy drive.
Price.
Easy to setup/configure.

Cons: None really. Would maybe be nice to be able to unlock the 2 other cores on my AMD Phenom II X2, but I wasn't expecting it to.

Overall Review: I purchased this in 2009 and honestly didn't really think I'd still be running it in 2017. It's been in 3 different cases, had different hard drives (IDE and SATA) and video cards installed, have had Windows XP, Vista, 7, and even 10 (which it currently has) installed, and have upgraded the RAM, and I've had zero problems with it and it's been on almost 24/7 and has been my gaming and audio/video editing machine, so I've pushed it quite a bit. It'll be a sad day when I finally end up replacing it with a more modern board from 2017/18.p

I like it 11/8/2013 7:54:14 AM

Pros: Basically plug and play. Wish it supported more RAM

Cons: Driver disc doesn't include Win7 drivers. Need to download these. Some of the mobo apps seemed to have trouble with WinXP-x64

Overall Review: A solid board. The rear connectors didn't line up well with my case, but I don't know if that's the mobo or the case.

Very Satisfied 7/13/2011 2:32:10 PM

Pros: Plenty of USB slots, Sata Ports, Works Fast, love the 4 DDR2 Slots and the number of extra PCI slots it has.

Cons: just no video, and whatever you do. DO NOT UPDATE THE BIOS!

Overall Review: When I updated the BIOS downloaded from the asus website, things got very bad and at some point I couldnt get into bios and the CD that comes with it says the BIOS is too old for that motherboard...But I called ASUS and they did not hesitate to give me a replacement and that replacement came in fast! So I'm really satisfied with this product and ASUS.
