Gigabyte Readies Entry-Level Graphics Card GV-N640D5-2GI

Gigabyte is going to introduce one more entry-level graphics solution that corresponds to the updated Nvidia GeForce GT 640 series. Entitled Gigabyte GeForce GT 640 (GV-N640D5-2GI), the card employs GK107 GPU, running at 1046 MHz frequency instead of the preceding 900 MHz. The core, developed under 28 technological process, utilizes 384 CUDA cores.

It’s necessary to underline that the new-comer differs by the availability of 2 GB memory, whereas all etalon models take 1 GB only. Memory is represented by 64-bit GDDR5 chips that run at 5010 MHz effective frequency, if compared with 1800 MHz frequency that DDR3 modules demonstrate.

GV-N640D5-2GI comes with an improved design of PCB where a brand Ultra Durable 2 concept has been incorporated. This concept implies the employment of a high-quality hardware base, involving durable solid-state capacitors, transistors with low channel resistance RDS (on), and ferrite throttles with reduced power loss. Traditionally, the model …

Review of the universal cooler for graphics cards Ice Hammer IH-900B

With an excellent combination of cost and efficiency, cooling systems Ice Hammer continues to advance steadily to our market, crowding out products over top manufacturers. Today the characteristics, efficiency and noise level of another novelty — a cooler for graphics cards Ice Hammer IH-900B will be studied.

The novelty comes in a compact cardboard box with a small cutout on the front side, through which part of the fan and radiator is visible. On the reverse side there is also present cut-out in the form of the cooler. There is a list on GPU graphics cards from NVIDIA and AMD, which is compatible with the Ice Hammer IH-900B. On the sides of the package you can find specifications and other information about the cooling system.

Along with the cooler are supplied: small aluminum heatsinks for memory chips and smaller radiators for power elements, two sets of sleeves, key pads and screws, and a brief installation instruction, thermal compound A2, cables, adapters, as well …

Antec Replenishes High Current Gamer M Series with Two New PSUs

Antec decided to expand its renowned High Current Gamer M series of power supply units with two new models. Codenamed HCG-750M and HCG-850M, the units are characterized by modular cable connectivity and rather high level of efficiency (up to 81% in 230V networks). Not for nothing this couple is honored by 80Plus Bronze certificate that vindicates their prime-quality. It must be noted that existent internal framework is totally the work of Seasonic, Antec’s contractor.

Both new-comers are equipped with four PCI Express Power (6+2)-pin cables and support 10/12/14/16-contact power sockets. The layout consists of two virtual +12V rails, Active PFC mechanism, and high-class Japanese capacitors. HCG-750M allows for the maximal loading on +12V rail of 62A at 744W, whereas HCG-850M allows a bit higher loading of 70A at 840W.

With the purpose to prolong the units’ lifetime, Antec furnished the models with all up-dated security functions, featuring: UVP (low voltage protection), …
