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 …

Meet Pure Power 9 CM Top Series of PSUs from Be Quiet!

Be Quiet! enters the market with a new series of power supply units, entitled Pure Power 9 CM. The lineup includes models of 400 W, 500 W, 600 W, and 700 W power. All of them boast the implementation of Active Clamp + SR topology with high-quality hardware base. Besides, the manufacturer decided to ditch group mechanism of voltage stabilization; this promoted for more efficiency which index achieves 91%.



High efficiency level allowed Pure Power 9 CM units to receive 80Plus Silver certificate. The 12V bus is divided into two lines with the maximal load capacity. Cooling process is attached to a single low-noise 120-mm fan, based on rifle bearing (100 thousand hours MTBF). Its maximal rotational speed varies within 1060-1680 RPM range.


To continue, Be Quiet! has incorporated into the models all possible security mechanisms, including OPP, SCP, UVP, OCP, and others. The units come with an additional Surge Absorber filter that protects the circuitry from voltage surges. …
