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 …

PSU Enermax Revolution87+ 750W Review

This year has become rather successful for Enermax, a well-known manufacturer of power supply units. The company supplemented its product lines with six series combined into four major groups: entry-level, athlete, royal, and gold class. Revolution87+ series belongs to the Gold Class group and involves five models (from 550W to 1000W power). Model Revolution87+ 750W is distinguished not only by the availability of 80Plus Gold certificate, but also by an original branded platform developed by Enermax specifically for this series.


Enermax has implemented a few striking technical solutions in its Revolution87+ 750W power supply unit. The first attractive feature is a composite control over the main inverter. The control is realized by traditional pulse-width modulation method, as well as by simultaneous involvement of pulse-frequency modulation (the combination of width and frequency in control process).

Upon the whole, this PSU model is able to demonstrate up …

Scythe Showcases a New Affordable Kotetsu Cooler

Scythe has recently showcased its newest CPU cooling system with an expressive codename Kotetsu. Relying much on the demands of average customers, the product offers an optimal correlation of efficiency and price. The Kotetsu is an ordinary tower-like product with a perfect cooling potential. However, its key advantage is the employment of Hyper Precision Mounting System, which ensures fast and trouble-free installation.

First and the foremost, Scythe Kotetsu is ready to work with all current CPU platforms, including Intel Socket LGA1150 and AMD Socket FM2+. Heat dissipation efficiency is realized thanks to a large number of aluminum fins, incorporated into the heatsink, as well as four heat-pipes of 6 mm each. The heatsink features an extraordinary shape that ameliorates the airflow between the fins. Therein, contact base is entirely made of copper.

Second of all, this cooler is initially equipped with one 120 mm fan, entitled Scythe Glide Stream. Due to PWM support, it …
