Gigabyte Z77X-UD3H and Z77X-UD5H Pictured, Too

Here are the Z77X-UD5H and Z77X-UD3H pictured up-close. The two form Gigabyte's upper-mid range and mid range offerings based on the Intel Z77 chipset, supporting socket LGA1155 "Ivy Bridge" and "Sandy Bridge" Core processors. The Z77X-UD5H is an extremely feature-rich offering, in some aspects a more complete package than even the G1.Sniper 3. It provides a 15-phase CPU and 2-phase memory VRM. Expansion slots on this board include two PCI-Express 3.0 x16 (x16/NC or x8/x8), one PCI-Express 2.0 x16 (electrical x4), three PCIe 2.0 x1, and one legacy PCI.



SATA connectivity on the Z77X-UD5H includes five internal SATA 6 Gb/s (two from the PCH, three from third-party controllers), four SATA 3 Gb/s, one mSATA, and one eSATA. Display I/O includes one each of DVI, D-Sub, HDMI, and DisplayPort. There are two gigabit Ethernet interfaces (one driven by an Intel controller, one by a Qualcomm-Atheros controller), 8+2 channel HD audio driven by Realtek ALC898, ten USB 3.0 ports (four on the rear panel, six via front-panel headers), FireWire, and a number of USB 2.0 ports.




Moving on to the Z77X-UD3H, we find a leaner loadout overall. A 9-phase VRM powers the CPU, 2-phase memory. The expansion slot arrangement is identical to that of the Z77X-UD5H. SATA connectivity includes two SATA 6 Gb/s, four SATA 3 Gb/s internal ports, one mSATA, and two eSATA ports. This board has even more USB 3.0 ports than the UD5H: six on the rear-panel, two via header. The rest of the connectivity includes 8+2 channel HD audio (VIA-made CODEC, we're not too sure about the 108 dBA SNR marking), one gigabit Ethernet interface (likely Realtek 8111F). Display connectivity includes one each of DVI, HDMI, DP, and D-Sub.




Both motherboards support NVIDIA SLI and AMD CrossFire, although support for Lucid VirtuMVP was not noted. The mSATA ports give users easy access to SmartResponse technology. Both boards feature gunmetal black PCBs, with blue PCH/VRM heatsinks. Both models will likely be part of the first wave of Z77 motherboards.

Gigabyte G1.Sniper 3 Z77 Motherboard Pictured

How time flies. It's been just a little over an year since Gigabyte unveiled its G1.Killer series of gamer-overclocker oriented motherboards, including the G1.Sniper, and now it's already at G1.Sniper 3. While the original G1.Sniper was based on the X58 chipset supporting LGA1366 processors, the the Sniper 2 based on Z68 chipset, supporting LGA1155 processors, the Sniper 3 stays put on the LGA1155 platform, but makes use of the brand-new Z77 chipset. The motherboard is designed to drive up to four graphics cards in 4-way CrossFire/SLI configurations. It takes advantage of a PLX PEX8747 bridge chip, which takes in one PCI-Express 3.0 x16 link, giving out two PCI-Express 3.0 x16 links, it even has a native multiplex that splits its second downstream x16 link to two x8 links. This way, the G1.Sniper 3 is ready for 4-way action with the latest PCIe Gen. 3.0 graphics cards.



The socket LGA1155 CPU is powered by a 15-phase VRM. It is wired to four DDR3 DIMM slots supporting dual-channel DDR3 memory. Expansion slots include four PCI-Express 3.0 x16 (x16/NC/x16/NC; x16/NC/x8/x8; x8/x8/x8/x8); two PCI-Express 2.0 x1 (wired to the PCH), and one legacy PCI. There's a boat-load of SATA connectivity, starting with six SATA 6 Gb/s ports (two from the PCH, four from additional controllers), four SATA 3 Gb/s, and one mSATA 6 Gb/s. For a change, Gigabyte did away with both Creative X-Fi audio (at least the CA20K2-based version) and Bigfoot Killer NIC, and replaced them with more familiar parts, such as HD audio (probably Realtek ALC898) driving the audio, with better ground-isolated amp circuitry, and Intel Gigabit Ethernet controller (probably 82579V). There's a second GbE connection, driven by a Realtek controller.




Display connectivity looks to include DVI, D-Sub, HDMI, and DisplayPort (the whole lot). All USB ports on the rear panel are USB 3.0, four of them could be wired to the PCH. There are a number of USB 2.0 ports available by headers, not to mention two more USB 3.0 ports via front-panel header. Moving on, the G1.Sniper 3 has Gigabyte's dual-UEFI BIOS with 3DBIOS UI. While the board retains the gunmetal black+green color scheme, it did away with retarded-looking heatsink designs. It packs a whole bunch of features for overclockers, including consolidated voltage measurement points, a feature-rich BIOS, etc. The G1.Sniper 3 could feature in Gigabyte's first wave of Z77 motherboards.



ASUS P8Z77-V Deluxe Starts Selling in China

Chinese online marketplace site Taobao has listings of two yet-to-launch motherboards based on the Intel Z77 Express chipset, the Wibtek Z77 Hacker (we earlier covered news of that listing in early January) and now, the ASUS P8Z77-V Deluxe. This will be among ASUS' premium LGA1155 motherboards based on the new chipset. It is priced at 2,499 RMB (US $396), which seems overpriced. The seller is probably looking to make a quick Mao with pre-launch orders. The seller was kind enough to paste ASUS' marketing poster for the P8Z77-V Deluxe, which can typically also be found on the back side of product packaging.

The P8Z77-V Deluxe supports DDR3-2800 MHz with overclocking. Expansion slots include two PCI-Express 3.0 x16 (x8/x8 when both are populated), wired to the CPU, supporting NVIDIA SLI, AMD CrossFire and Lucid VirtuMVP; one PCI-Express 2.0 x16 (electrical x4, wired to the PCH); and four PCI-Express 2.0 x1 slots. Good riddance to legacy PCI. Display connectivity lacks archaic connectors such as DVI and D-Sub, includes HDMI and DisplayPort, instead. Storage connectivity consists of four SATA 6 Gb/s (two from the PCH, two from a third-party controller), four SATA 3 Gb/s, and two eSATA 6 Gb/s.



Other connectivity includes two gigabit Ethernet interfaces (one driven by Intel 82579V, one by Realtek RTL8111F PHY); Wireless b/g/n (quad-band); Bluetooth 3.0; 8+2 channel HD audio (Realtek ALC898 HDA CODEC); 8 USB 3.0 ports (six on the rear panel, two via front-panel header); and 8 USB 2.0 ports. There are several ASUS-exclusives to be had, such as its UEFI BIOS with EZMode, EPU, TurboV Processing Unit (TPU), etc.
