Two PCI-E x1 slots are also present on the Z87 OC Formula, as well as a mini PCI-E port that houses a WiFi card on the /AC variant. The lanes are shared out by a PLX PEX8605 switch, hence using the slot will force one of the internal USB 3.0 headers to operate at USB 2.0 bandwidth. Number crunching users, on the other hand, will very much appreciate the fourth x16-length slot. The bottom x16-length slot is limited to PCI-E 2.0 x4 bandwidth, hence 4-way CrossFire isn't really an unhampered possibility. The flexibility given by AMD's CrossFire support allows the board to support all configurations up to 4-way. When a three-way graphics configuration is installed, sixteen PCI-E Gen 3 lanes from the processor will be split as x8/x4/x4.ĭue to the fact that a maximum of two slots can operate at x8 bandwidth, the ASRock Z87 OC Formula only officially supports 2-way (two cards) or quad-SLI (two dual-GPU cards). Due to the lack of a PLX PEX8747 (or equivalent) PCI-E 3.0 lane switch, the ASRock Z87 OC Formula is only able to support three cards at Gen 3 speeds. Two CPU fan headers, one 4-pin and one 3-pin, are found above the DIMM slots and upper edge of the MOSFET heatsink.įour PCI-E x16-length slots give quad-VGA capabilities to the Z87 OC Formula. The CPU socket itself features 15 micron gold fingers.īoth of the Z87 OC Formula's Hi-Density 8-pin CPU power connectors are found in their typical location near the VRM heatsink. ASRock's OC Formula power kit consists of Dual-stack MOSFETs, multiple filter caps (MFC), premium alloy chokes, and a digital controller. Twelve power phases feed an LGA 1150 CPU installed in the Z87 OC Formula motherboard.

A quick measurement indicates that the pipes' internal diameters are one-quarter inch (0.25″ or 1/4″), but we will update this article with verification from ASRock before confirming the compatibility. Thankfully, ASRock's implementation is acceptably quiet when operating in the standard speed mode we couldn't hear it above the Corsair H100i's fans which were spinning at a low RPM.Īt the time of writing, we are waiting for confirmation from ASRock as to the exact diameter of the watercooling barbs. I usually frown upon use of a VRM heatsink fan when it isn't entirely necessary as they tend to be very loud. Called Twin-Power Cooling, the heatsink uses a small 3-pin fan to blow air over the structure.

Overclocking frequency is adjusted by the plus and minus buttons, while the ‘Menu' version allows users to change what is displayed on the status OLED.ĪSRock's Z87 OC Formula motherboard features an actively-cooled, hybrid VRM heatsink that is designed for air- or water-cooling systems. The system consists of plus, minus, and menu buttons, as well as two sets of voltage reading points (called V-Probe) and the CHiL controller.
Towards the top-right corner of the Z87 OC Formula, users will find the onboard overclocking tools. LN2 and slow boot modes are designed specifically for high-frequency overclocking with extreme cooling. The lane switch is convenient for extreme cooling users as they can easily disable the function of a problematic graphics card rather than tear apart the entire cooling loop. Neighbouring the USB 3.0 headers are three switches that operate the PCI-E x16 lane operation, LN2 mode, and slow boot. We would typically criticise a board manufacturer for giving both headers the outwards-facing orientation, but given the likelihood that the Z87 OC Formula will be used on test bench, not a chassis, this isn't nearly as big of a complaint. Going one further than many of its alternative products, ASRock gives the port USB 3.0 functionality, rather than the slower, previous-generation interface that is found on many other motherboards.Ī pair of outwards-facing internal USB 3.0 headers is found in the usual position that gives easy access for front panel chassis cables. We will be putting the high-speed memory support claim to the test with a 3000MHz kit from Avexir.Īn addition that we have seen become increasingly popular amongst many of ASRock's Z87 motherboards, the Z87 OC Formula is equipped with an internally-mounted USB port. Although we wouldn't say that the design is as attractive as that of MSI's Z87 XPower, or Asus' Maximus VI Extreme, the OC Formula's appearance is still very likeable.Ĭonforming to the Extended-ATX form factor, the ASRock Z87 OC Formula is designed for use on test benches (or the bundled OC stands) or large cases that can accommodate the board's wider dimensions, such as our NZXT Phantom 630.įour alternating black and yellow, single-latch DIMM slots can house up to 32GB of DDR3 memory operating at frequencies of over 3000MHz.

Featuring the bright yellow and dark black colour scheme that made ASRock's OC Formula series of motherboards well-known on the Z77 platform, the Z87 version is an undoubtedly eye-catching product.
