Asus Maximus Extreme and P5E3 Premium

Maximus Extreme: Specs and Bundle

Next up we have Asus' flagship motherboard in the R.O.G. (Republic of Gamers) series of products, the Maximus Extreme. Although the Maximus Extreme is based on the X38-chipset, it supports front side bus speeds up to 1600MHz and DDR3 speeds up to 1800MHz, just like the X48.  Through BIOS tuning and selective binning of the chipsets, Asus' Maximus Extreme offers an essentially identical feature set to the X48, as you can see below.

Asus Maximus Extreme
Specifications and Features


Lke the P5E3 Premium, the X38-based Maximus Extreme ships with a wide array of bundled goodies.  Along with the board itself Asus throws in six SATA cables, a single SATA power adapter, floppy and IDE cables, and a case bracket with additional USB and Firewire ports. In addition to these items, we also found an electro-luminescent custom, I/O shield, three thermal probes, a pack of foam stand-offs, a baggie with wire ties, another baggie with fittings and clamps for all types of liquid-cooling systems, a user’s manual, a pack of Q-Connectors, a couple of optional fans that can be mounted to the board’s cooling apparatus, and a driver and utility DVD complete with copies of Asus' PC Probe II and AI Suite, 3DMark06, and KAV (among other things). Asus also includes a SupremeFX II audio riser card which is powered by an ADI 1988B 8-Channel HD audio CODEC, an "LCD Poster", and a copy of the excellent game S.T.A.L.K.E.R.


The LCD Poster is an interesting addition to the bundle.  While it doesn't do anything extraordinary in comparison to most other LCD POST code error reporters, it is far more convenient to use.  The Asus LCD Poster is unique in that it connects to the board via a long cable and can be placed right on a desktop.  There is no need to bend down and peer into a system to read the LEDs mounted on the PCB itself – with the Maximus Extreme, the error codes are clearly visible right on the LCD’s screen, wherever a user decides to mount it.
