Product information: M5A99X EVO AMD 990X (Socket AM3+) DDR3 ATX Motherboard

ASUS has announced a new line up of AMD based motherboards that support the 990FX/990X/970 chipsets and AM3+ CPUs, the first company in the market to provide fully compatible AM3+ motherboards. The new motherboards will be the first on the AMD chipset based platform to support both multi-GPU technologies AMD CrossFireX™ and NVIDIA® SLI™.

The M5A99X EVO series offers unsurpassed compatibility with new AMD AM3+ socket CPUs, whilst also being backwards compatible with the previous generation AM3 CPU. The M5A/99 core series is equipped with DIP2, which features DIGI+ VRM technology in addition to the TPU and EPU. DIGI+ VRM power delivery allows users to precisely adjust and control power settings digitally for precise power control and flexible tuning of their system, perfectly serving the AM3+ CPU specification’s power demand. Digital control differs from analogue controls by eliminating digital to analogue conversion lag, which helps to improve overclocking capabilities. This means precise power flow adjustment and management as well as easy and flexible tuning including extra DRAM power control for the AMD platform. It is the most precise power delivery available, providing the best-in-class in power efficiency, performance and stability while also helping to maximize the overall overclocking potential.

Also included on the M5A99X EVO is the intuitive UEFI BIOS menu interface. UEFI BIOS allows a user to control and adjust their BIOS settings through the use of a mouse-enabled interface for more user-friendly navigation. The built-in EZ Mode option also provides a drag-and-drop boot priority option, for easier management of boot devices.

Excellent mobo. Never overclocked before, so I tried the TPU overclocked my amd phenom x4 965 black edition from 3.4ghz to 3.7ghz. Its max temps are 58 c which is while rendering videos, average is 48 c. And thats with the stock heatsink.

Harry 2011-12-14


Got this board for my new system and what can i say, For the money you pay it's packed full features, That are easy to use. Asus had there head screwed on when they built this.

I got an AMD phenon 2 Hex core 1090T @ 3.2 along with 2X asus GTX 560's on SLI and 8GB of Corsair Vengeance 1866MHz Dual Channel DDR3, ocz 60GB SSD. Overclocking was easy reaching 3.884ghz @1.41V on the CPU while staying stable. This system Has run everything i throw at it maxed out.

Just buy one! you really really wont regret it!

Building pc's for a living, mainly custom gaming rigs, Asus have definetely delivered on this Board, and not skimped either, build quality is rock solid, overclocking is fab, and the EUFI bios is excellent.

mark 2011-11-02

very very good

very nice looking board, easy to set up and it has some nice features. the bios is very nice to use especially as you can use the mouse making it user friendly. I have this paired with an 8 core and 16 gb of ram and i must say its an awesome combination. highly reccomended. Thanks overclockers good service as ever!!!!!!!!

Adam 2011-10-08

Very Good Value

I recently bought the motherboard and it is extremely easy to setup. The bios is excellent easy to overclock and runs perfectly.

Definitely worth the money.

Gareth 2011-09-12


Fantastic motherboard, very easy to use and a Bios that is just a pleasure to work with.

One thing that hasn't been noted in any of the other reviews is the onboard sound - it's top notch.

A good product, well worth the money.

Asus M5A99X EVO AMD 990X

awsome board , cant fault it running Phenom II 975 @ 3.9 and 12 gig ram , prob best asus board for money and good news its bulldozer ready

Carl 2011-08-05

Brilliant Value

Running with a Phenom II X6 1055T. Significantly faster than my old Core2 Duo E8500 and 790i Ultra setup, which this replaces. Well built and laid out. I love the TPU switch, simple flick and the cpu clocks to its max. This board is supplied with a modest amount of accessories. Tho its enough for me personally.

My first venture into UEFI BIOS... and looking good.

Only thing letting this down, is the uber hot GTX470, which is soon to be replaced!

Sam 2011-07-30

5 Stars

Had the board a couple days now and it's great, the bios is the best i've used on a ease of use term and with the flick of a switch my 1100t was clocked to 3.84GHz, plenty of room between cards if you want to run sli/crossfire, nothing to moan about with it.

Soundood 2011-06-28

Bang for Buck? hell yeah

OK, where do i start, AM3+ Ready (Bulldozer) supports SLI and Crossfire, USB3 and Sata 6 gig, it has lighty up things too. all for this price? what is there to think about?

my set up has a 1100t @ 3.7gig, temps running at 28C on water.

i also have two GTX470's in SLI, you have concerns over the x8 lanes per card? dont, i have run many benches and its the exact same as i got on my M4A79 Deluxe, that had x16 lanes on each slot.

the board itslef has a great build quality, it feels and looks much better than expected, i was only going to get this too tide me over for 3-4 months, but that has changed this is a keeper.

and finaly UEFI bios? what can i say...wonderful. im old school, and thought i would be a bit odd about it, but it is great, really i dont think i would go with a board now that didnt have this.

dont wonder, just buy it, you wont be disapointed.
