GeForce GTX 480 Supports 4-way SLI?

Soon after EVGA laid its hands on stocks of GeForce GTX 480 graphics cards, it claims from an internal test that 4-way SLI is possible on the reference design GTX 480 graphics cards. The GTX 480 was advertised to work with up to two more of its kind in 3-way SLI, in NVIDIA's presentations to the press. EVGA's feat of running four GTX 480 cards was possible on its X58 Classified 4-way SLI motherboard, which has room for four graphics cards, and a special SLI bridge that connects to four NVIDIA graphics cards with two SLI interconnect bridges each. EVGA released a special-edition GeForce GTX 285 4-way SLI ready graphics card to go with the motherboard.

The EVGA X58 Classified 4-way SLI isn't the only motherboard to support 4-way SLI, the recently released EVGA Classified SR2 also ships with the special SLI bridge. No other motherboard vendor released a 4-way bridge, yet. EVGA demonstrated the 4-way SLI setup with a run of Unigine Heaven, although it did not give away any performance numbers. 4-way SLI is not to be confused with Quad-SLI, which is also a four-GPU SLI configuration, but involves a 2-way SLI connection between two dual-GPU graphics cards (such as GeForce 9800 GX2, GTX 295, MARS). Any SLI-supportive motherboard supports Quad-SLI.

ASUS Introduces P7F7-E SuperComputer Motherboard with Next-Gen Connectivity Features

ASUS today announced the launch of the new ASUS P7F7-E WS SuperComputer motherboard which maximizes transmission speeds by integrating the industry's latest I/O technologies such as USB 3.0, SATA 6G storage interface, and IEEE 1394b FireWire standard. Additionally, the ASUS P7F7-E WS SuperComputer is equipped with the LGA1156 socket and the latest Intel 3450 chipset with onboard graphics. For extreme gaming enjoyment, up to four ATI CrossFireX cards or 3-way/2-way NVIDIA SLI cards can be accommodated to generate smoother and sharper visuals. It also leverages NVIDIA CUDA parallel computing architecture to support up to four NVIDIA Tesla cards with Clarkdale Processors for intensive high-performance computing.

The ASUS P7F7-E WS SuperComputer is the best choice for providing comprehensive I/O support. It includes USB 3.0 ports—the latest connectivity standard with 4.8Gb/s speeds—to support next-generation components and peripherals. USB 3.0 transfers data ten times faster and is backward compatible with USB 2.0 components. Additionally, the ASUS P7F7-E WS SuperComputer includes Serial ATA (SATA) 6Gb/s storage interfaces for 6.0Gbps data throughput, thus enhancing scalability, accelerating data retrieval, and doubling the bandwidth of current bus systems. To support FireWire-enabled digital video recorders and computers, the ASUS P7F7-E WS SuperComputer also includes two IEEE 1394b ports supporting up to 800 Mb/s speeds—doubling the previous IEEE 1394a speeds.

GeForce 196.78 Beta Driver Runs GeForce GTX 470

Czech technology website PCTuning confirmed a few details about NVIDIA's upcoming performance graphics accelerator, the GeForce GTX 470. It was found out that a beta driver by NVIDIA, GeForce 196.78 supports GeForce 400 series accelerators, and was able run a qualification sample of GeForce GTX 470. The card was using A3 revision GF100 silicon. The driver's System Information dialog revealed that the card indeed has 448 CUDA cores (SIMD units). Further, it has 1280 MB of memory, and a 320-bit wide memory interface. NVIDIA also changed the way it represents memory clock speeds. Since it is using GDDR5 memory, while the memory has an actual clock speed of 1000 MHz, the data rate (DDR speed) is represented first, as 2000 MHz, and "effective speed" next, which is 4000 MHz.

Given these speeds, at 1000 MHz GDDR5, the GPU has a memory bandwidth of 160 GB/s. Without compromise on looks and quality, NVIDIA kept the cooler design basic. It has a matte finish. Display outputs include two DVI-D, and one mini HDMI. It supports NVIDIA 3D Vision Surround (a technology competitive to ATI Eyefinity, to span a display head across multiple physical displays), just that NVIDIA requires at least two accelerators in SLI to use it. NVIDIA's GeForce 400 series graphics accelerators will be launched on the 26th of this month.

Galaxy Designs Dual-Core GeForce GTS 250 Graphics Accelerator

Whereas NVIDIA is inching towards releasing its DirectX compliant GF100 GPU from which it has high expectations, some of its partners don't seem to give up on the two-generation old G92. Galaxy has almost finished designing a graphics card that uses two GeForce GTS 250 GPUs on one PCB, in an SLI on card setup. It refers to the card as "DualCore GTS250", and consists of a long blue PCB which holds two G92-426 GPUs (G92-426 GPUs are used on low-power variants of the GTS 250).

Each GPU is wired to 1 GB of GDDR3 memory across its 256-bit wide memory interface (total 2 GB on board). The two GPUs are connected to the system over an nForce 200 BR-03 bridge chip. The multi-GPU system is contained within the board, with no SLI fingers for expansion, even though G92 chips are Quad SLI capable.

EVGA Releases SLI Enhancement Patch v20

EVGA finished its twentieth release of the EVGA SLI Enhancement Patch, a software that adds to the GeForce system drivers' SLI profiles specific to applications. These SLI profiles help applications take advantage of multiple GeForce graphics cards in SLI, or dual-GPU GeForce accelerators such as the GeForce 9800 GX2 and GeForce GTX 295. Version 20 (01.15.10) adds SLI profiles to Dark Void, Serious Sam HD, and Avatar (Demo). This patch is based on GeForce drivers 195.81. The latest version of GeForce drivers from NVIDIA bring SLI profiles to the latter two games. Registered EVGA users can download the software from here.

EVGA Announces GeForce GTX 275 Co-op Graphics Accelerator

EVGA's Halloween offering, the mystical graphics accelerator with two different GPUs - each handing one kind of task - is official. Behold the EVGA GTX 275 Co-op PhysX accelerator. This unique graphics accelerator uses an NVIDIA GeForce GTX 275 GPU to handle the primary task of graphics processing, while offloads GPGPU related tasks, such as game physics acceleration using the company's PhysX technology, to a second GeForce GTS 250 GPU. While the GTX 275 component has 896 MB of GDDR3 memory across its usual 448-bit wide interface, the GTS 250 has 512 MB of it across its 256-bit wide interface, 1280 MB total on board (though not the total amount of memory available to a 3D application).

While not intended to be a true dual-GPU accelerator in essence that the two GPUs work in tandem to render graphics, the design ensures that the GeForce GTX 275 works with zero overhead from processing PhysX. The two GPUs are not part of an SLI multi-GPU array. With the provision of two SLI fingers, users can pair up to three of these in a 3-way SLI array. It is logically possible to pair this with other normal GeForce GTX 275 accelerators as well.

EVGA Releases SLI Enhancement Patch v18 (10.22.09)

Staying ahead of NVIDIA and its own series of similar software, EVGA released the 18th edition of its SLI Enhancement Patch. The SLI Enhancement Patch is a piece of software that adds SLI profiles of usually new games to the NVIDIA GeForce driver. SLI profiles optimize help applications take advantage multiple NVIDIA GPUs installed in an SLI setup. Version 18 of the software is based on NVIDIA GeForce 191.07 drivers. It adds or enhances SLI support for the following games. Registered EVGA users (registration is free) can download the software from here.
  • Enables SLI support for Borderlands

Gigabyte Readies GA-P55A-UD4 with SATA 6 Gbps and USB 3.0

Gigabyte is readying a new socket LGA-1156 motherboard, the GA-P55A-UD4. Bearing resemblance with the GA-P55-UD4, the motherboard features upgraded connectivity, with support for USB 3.0, and SATA 6 Gb/s. The new model also features an upgraded CPU VRM, with a 12+2 phase design compared to the 8+2 phase design on the GA-P55-UD4. USB 3.0 and SATA 6 Gb/s features are provided using additional controllers on board. A Marvell-made SATA 6 Gb/s two-port controller replaces the familiar Gigabyte GSATA2 controller, while an NEC-made controller provides two USB 3.0 ports on the rear-panel. The USB 3.0 ports are color-coded blue, and share the port cluster with the lone gigabit Ethernet connector, while the SATA 6 Gb/s connectors are color-coded white, next to the usual six SATA 3 Gb/s ones the P55 PCH provides.

The rest of the feature-set remains largely same, with four DDR3 DIMM slots to support up to 16 GB of memory, two PCI-Express 2.0 x16 slots (electrically x8 when both are populated) supporting ATI CrossFireX and NVIDIA SLI, Dolby Home Theater supportive onboard audio, among other standard issues. The Gigabyte GA-P55A-UD4 will not replace GA-P55-UD4 from the market, it will coexist, albeit priced higher. It remains to be seen if this is the only "P55A" motherboard Gigabyte sells.
