HIS submitted a non-reference card Radeon HD 7970 X

Hightech Information System Company has completed the development of its secret weapon — the video card HIS 7970 X. The relatively modest-looking product, according to producer’s statement, is equipped with a (18 +1 +1)-channel power supply system, high-performance cooler IceQ X2 and non-standard set of ports — four Mini DisplayPort, single DVI and HDMI. The technology AMD Eyefinity 6 is supported — simultaneous work with six monitors. Clock frequency speeds up model 1000/6000 MHz for core and memory respectively. Hong Kong vendor assigns a novelty to a class of graphics cards Radeon HD 7970 GHz Edition.



The cooler is composed by a copper base, three 6-mm and two 8-mm heat pipes, ribs (cooler chips on the VRM and RAM), an aluminum radiator. A pair of 90-mm fan cool the core of Tahiti XT (2048 shaders, 384-bit memory bus) which combines with 3072 MB of memory GDDR5. Additional power is provided by two 8-pin connectors PCI-E Power, in addition memory individually powered …

Three-Dimensional Monitor HP 2311 GT Review

Three-dimensional technology applied in PC monitors enjoys popularity primarily with more well-to-do people rather than general public. This can be simply explained by the price aspect attached to the issue: 3D monitors with all accompanying equipment are a costly acquirement, and not every customer is ready or can afford buying them for home use. Hewlett-Packard company always tries to comply with the demands and possibilities of their consumers; however, the company does not forget about the development and innovations. Thus, HP delivered three-dimensional monitor with passive polarized 3D technology, codenamed HP 2311 GT.



Design and Specifications


First of all, it should be mentioned that HP 2311 GT is basically oriented on the entry level customers, and this is vindicated by the moderate price policy ascribed to the series. The casing is made of plastic with mould base; this base does not allow any alterations in monitor's height or rotation. The tilt can be adjusted …

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.



The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.


As the advantages of such solution can immediately be noted a lower price, due to less stringent …
