Here is the complete laundry list: Specifications CPU Specifications and FeaturesĪs usual, ASUS has one of the longest feature sets you’ll ever find. I don’t even really like the red/black RoG theme, but what they did with it here is second to none. Top to bottom this is one of the best looking motherboards out there. I like the IV Formula, but the V is in a class by itself. ASUS Crosshair V Formula, In the Fleshįirst impression: this is one really good looking board. You didn’t come here to see the box though let’s pull the board out and have a look at it from plenty of angles. There are detailed specifications as well as feature highlights all over. There is a flap covering a window that allows you to peer into the board without even opening up the box. Packaging and First LookĪSUS doesn’t fix what isn’t broken and they’ve presented their Crosshair V Formula as they did the Crosshair IV series before it. The Formula houses AMD’s newest chipset, the 990FX northbridge and SB950 southbridge. On my 3-pin chassis fans the adjustable range is 40 - 100% for power and 0 - 100☌ for temperature.Ĭ) PWM is better because instead of altering the voltage it alters how often the voltage is applied so you could have a fan that won't run at all below a certain voltage but with PWM control the full voltage is applied in pulses so you can get a lower RPM on a fan that you couldn't with just voltage control.Today we look at ASUS’ top of the line AMD board, the Crosshair V Formula. EDIT: I think that OPT_Temp sensors need to be connected for the fans to change speed, otherwise the fan will just spin at a constant speed.ī) the FAN Xpert graph in windows shows 0 -100% on the power Y-axis and 0 - 100☌ on the temperature x-axis and on mine with a PWM CPU Fan the adjustment range is 20 - 100% for power and 0 - 100☌ for temperature. The other three fan headers (OPT_FAN1, OPT_FAN2 and OPT_FAN3) are controllable in the BIOS only and they can be in PWM mode or voltage mode. 3-pin fans are also controllable on the CPU_FAN header, I'm not sure about CPU_OPT though. The CHA_FAN1, CHA_FAN2 and CHA_FAN3 header work with 3 pin plugs and fan control is available via the BIOS or FAN Xpert in Windows.
