Layout

Already at a first glance the ASUS Rampage IV Formula looks very good with its harmonic design. Once again the ROG-colors - red, grey and black - suite nicely and together with the black PCB it becomes a very beautiful product. The layout itself is well thought and there is for example plenty of space around the CPU socket to install even todays largest CPU coolers. The fact that there are SATA connectors which have been angled by 90 degrees, allow an easy installation of oversized graphics cards like for example a Radeon HD 6990.

ASUS equipped the Rampage IV Formula with an 8+3 phase power design. In this case the CPU can rely on eight phases and the memory gets its own three phases. Furthermore each of the eleven pahses comes with new high quality "Black Metallic Chokes". These can resist much higher current (50A instead of 30A). In other words this means that one phase can cope with far more load than the predecessor.

Totally you'll find four DIMM-slots on the Rampage IV Formula. Officially supported are the following clock speeds: 2400 (O.C.) / 2200 (O.C.) / 2133 (O.C.) / 2000 (O.C.) / 1800 (O.C.) / 1600 / 1333 / 1066 MHz. There is also engough space between the DIMM-slots and the CPU socket which means that you wont encounter compatibility problems with big coolers even when you choose to install RAM with big heatspreaders.

Northbridge, southbridge as well as the current converters are being held at adequate temperatures via a passive heatpipe cooling solution. The cooling blocks haven been positioned wisely, which means that they don't collide with memory or CPU cooler. Fortunately ASUS decided to not install an active southbridge cooler.
