1-Preliminary and layout
ROG motherboards are the best of products ASUS. And today is again the "D" day for the AMD platform motherboards, and ready for the new CPUs AMD Bulldozer. For the BD launch every AMD fan impatiently waiting, now we can to shorten waiting in my motherboard preview.For AMD BD is today presented the new AMD chipsets 970/990x/990FX. Already we will see no 990GX boards, would lack sense of when they actually function replace better Llano, the APU from AMD.
Already a few days before the NDA a few photos of this "gem" escaped, but managed to conceal it long enough. The motherboard should have reportedly offered in two versions: with the expansion card Thunderbolt or without it. Additional card Thunderbolt is actually a combination of LAN and sound card in one case.
Look at the diagram of the motherboard. Crosshair Formula contains the highest chipset, AMD 990FX, that combines the RD990 northbridge and SB950 southbridge. In contrast, the 890FX chipset is functionally no much has changed. What is completely new, full digital processor power. As we can see, also support memory frequency 1866 MHz (only in case of casting Bulldozer) and a black socket AM3 + with 942 pins. Newly chipset can support SLI and Crossfire! All the particulars of how it communicates the CPU and the bridge is evident from the scheme.
Now itself the motherboard. Let's look first at the packaging .
But what is wrong? ROG restore to the old colors and also returned to quieter heatsink :rofl:
No, seriously, I had to make a small joke and show us photos first of Asus ROG boards Formula. Now you really look at the Crosshair motherboard V.
ASUS is green
As you can see, the motherboard looks really good. Has also changed the heatsink, which is very similary to heatsink of the Maximus Extreme IV, it was also recently totally separated from the southern bridge. Old motherboards have it connected via heatpipes. Strong segmentation of the VRM heatsink areas should dissipate heat more effectively than her sister last year Corsshair IV. At first glance you will notice other changes.
One of them is the AM3 socket +, is easier to distinguish from the AM3 is black. Also contacts for pin are diameters slightly higher. The reason is probably easier to handle with the processor and the correct insertion at the first attempt. If you are ever in the embedded processor shaking hand, you know what I mean. It is also a new attachment for the condenser. Box disappeared and instead we remained two sides. It has a reason for better heat dissipation of close to bottom. Dimensionally, however, nothing changed and the existing cooler for AM2 + / AM3 will fit. As overclockers would have pointed to the "clean" the area around the CPU socket. This will facilitate the stripping plates with plastic rubber. Here, ASUS thought well of overclockers.
Against layout boards do not object, its OK. Due to standard ATX size, could not even solve a combination of PCI and PCIe otherwise if we go in SLI or Crossfire, then we will use the first and third slot. PCI is located just between them, so would not conflict with each other to occur. Some people come to discuss the leaked photos of the location of the 'Start', 'reset', 'CPU Level Up. "In my opinion, they are placed correctly. Crosshair Formula IV, is still more the gameboard more than purely OC board and this mean which it allows to be placed in to PC case. Then it seems for my point of view the location of the buttons better than the example above near the memory slots. The Extreme version of it will certainly be different.
From below we look at a traditional backplate CPU cooling recently, the lower MOSFET. Positive is that the liabilities associated with the motherboard with screws, so no plastic pegs.
Now look at detailed pictures of the motherboard. I apologize in advance for the quality of photos, I've ever had, and invest in better camera and english learning course :rofl:
The first photo we see the pasives of the CPU mosfets, NB section. I was red framed the main voltage regulator, here is the ASUS Extreme Digi + (Chill). It is controlling the various phases. There are total 10 phases, of which 8 are for CPU and 2 for the remaining part uncore processor. Each phase has its own digital driver and in an emergency situation and the possible destruction of one phase others work still remaining. Furthermore, this switching phases used in the one function of the EPU. On the left side we see the memory slots (retail is going to have the opposite colored than my sample) in the left corner click the "Go button". This will be done by either the wrong post record safe profile memory (MEM OK) or when we are already in Windows, then a function of load profile over the OC hold the button. The function reaches into your BIOS settings in the "Go button file. Finally, at the bottom of the picture we perceive double the CPU power supply, and there is still 8pin and extra 4pin connector. This helps with hard OC, especially when overclocking with liquid nitrogen. Generally needed for Bulldozer harder supplied in extreme overclocking,higher than for Thuban. Recommend to watch this video:
Apart from the "Go button"and 4-pin power supply still can see voltage measuring points (named ASUS probelt). So, there is the ASUS ROG did not disappoint.
2-Mobo in details
Lets look at some photos in details.
The following two photos show us the area of PCIe slots. Those are five, four PCIe x4/8/16 and one PCIe x1. We can use both Crossfire and SLI that of the three or nVidia SLI graphics cards (must first install the drivers!). We can use 4SLI too, but will need to have self-Xpander desk. Primarily fitted again No. 1 slot for Crossfire, then slot 1 and slot 3 (identically true for SLI) for three slots, then SLI numbers 1,2 and 3. On the other hand, the TRI SLI will be used rather than regular overclockers ultimate player, and he absolutely does not need a PCI slot for overclockers each unused output useless. In addition to the PCI slot is located next to the battery and PCIe slots sticking southbridge. I was framed in red gradually chip ASM in 1061 to communicate with SATA / eSATA next to it is the clock generator and under the PCI slot is located a few controllers to control the PCIe slots. The previous figure is marked with ITE IT8721F chip. He is in charge of monitoring such as temperature and voltage, speed, PS2 outputs. Under the last PCI slot is located toward the left button on the OC "The OC level up" starter "Start" button and reset button to "reset". The following re-USB connectors (but now no standard USB 3.0).
Overall, board has 7x SATA ports 6GB, one SATA 3GB, one E-SATA 6GB, 6x USB3.0 ports, next 12x older USB 2.0 ports. It is possible to connect up to 8 fans! Board has support for RAID 0/1/5/10.
