Motherboard Biostar A55MD2 Review

Good overclocking facilities are what the majority of customers look for in contemporary motherboards. In this light, the manufacturers establish various price ranges, depending on the product’s overclocking potential. As usual, boards from budgetary lines cannot boast such potential, though there are some exclusions. Biostar A55MD2 is considered to be one of the cheapest solutions for FM2 platforms. Still, its layout marvels by the availability of CPU boost facilities, as well as gigabit network interface.

Design and Layout

Motherboard Biostar A55MD2 distinguishes itself by rather compact dimensions: 226x178 mm (uATX form-factor). The model accommodates an amplifying board that is made of a metallic fusible element. The chipset is cooled down by a small-sized aluminum heatsink, while field transistors are avoid of any cooler. This might signify about some inconsideration pertained to thermal environment. Power supply activity is realized by means of 24-contact and …

Chieftec Navitas Gets a 450-Watt Update

First launched in 2013, Chieftec Navitas series of PSUs included five high-efficiency models of up to 1250 W power. This year the company has introduced four new editions to the family which are characterized by low power: 450 W, 550 W, 650 W, and 750 W. This update is called to satisfy the needs of unpretentious customers who require stability rather than records.

New Chieftec Navitas power supply units come equipped with a single +12V bus that covers 100% power. Hence, it’s possible to integrate the models into the latest system configurations. All of them correspond to 80 Plus Gold standard, achieving up to 87% efficiency in a wide range of operational conditions.

Their other peculiarities involve a fully modular cable system, the availability of a low-noise 120 mm fan, the support for Active PFC technology and all known protection features (i.e. OPP, OTP, UVP, OVP, SCP).

To continue, Chieftec Navitas GPM-450S ensures 450-watt power on +12V rail & up to …

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 …
