Graphics Card HIS 7850 IceQ X Turbo X Review

The number of graphics solutions designed by HIS cannot be figured from a cursory calculation only. Indeed, the company's product line counts dozens of cards destined at various audiences, with various needs and budgets. Take HIS HD 7850 series alone: it consists of ten models (three with 1GB memory and seven with 2GB memory). The latest HIS 7850 IceQ X Turbo X belongs to '2GB echelon' and is distinguished by the heightened GPU and memory frequency. Upon the whole, this graphics adapter features outstanding cooling and overclocking facilities.



Design and PCB


Graphics adapter HIS 7850 IceQ X Turbo X is a standard representative of the second HD 7850 revision. It is housed on a short printed circuit board and is equipped with only a single power socket, two heatpipes and a large fan. HIS developers advanced the heatpipes outside the board to elongate its contours; nevertheless, this card can't be considered voluminous, since its width hasn't been touched at all. The top part …

All of them correspond to ATX12V v2.3 standard, support Active PFC option and a range of protection tools (from short circuit, overvoltage, current overload, power overload). Moreover, these units employ a dual EMI-filter and take benefit from a single 120 mm fan with automatic speed control functions.


Cooler Master G-series PSUs have been felicitated with 80Plus Bronze certificate, due to their high efficiency (approximately 85%) and an estimated mean time between failures of 100.000 hours. The two junior models, G500 and G600, are able to operate at 456W and 576W load, correspondingly, on +12V rail. They are quipped with six SATA Power sockets and a pair of PCI Express Power 6+2-pin sockets. G500 unit will come to the market at the price of €60, while …

The Latest Eisbaer Nonmaintained Cooling Systems Series from Alphacool Includes Six Products with 120/140/240/280/360/420 mm Heatsinks

Alphacool introduced its latest Eisbaer line of nonmaintained cooling systems for processors. This series offers six products differing in heatsinks’ dimensions (120/140/240/280/360/420 mm) and possessing one, two or three 120 or 140 mm fans. For higher productivity, all novelties are equipped with copper (not aluminium) radiators.



360 and 420 mm heatsinks may be regarded as overeffective for one CPU, that’s why the manufacturer supplied Eisbaer cooling systems tubes with a quick disconnect, allowing adding a water block for the Eiswolf GPX-Pro graphics card. The processor is chilled by a copper water block with the 50 х 50 mm base and a low-noise ceramic bearing pump, operating at 2,600 rpm and producing the 70 l/h coolant stream.


120 mm fans feature the 550–1,700 rpm rotary speed, the 63.85 CFM (108 m3/h) air flow, the 1.66 mm H2O static pressure, as well as the 29 dBA noise level, whereas bigger 140 mm fans have the 1,100 rpm rotary velocity, the 62.31 CFM (106 …

Hard disk controllers Yamaha, mudelite nimekirja

Valige mudel oma Hard disk controllers firmalt Yamaha loendist 54321 mudeleid, mis on esitatud sellel lehel. Meie andmebaasis on üle 654963 draiverid, mida saab alla laadida täiesti tasuta.

Kõvaketta kontroller – сложнейшее seade, эдакий mini, millel on oma protsessor, микросхемой juhtimine, RAM ja ROM, kanalite kirjutada ja lugeda andmeid, интерфейсным mooduli ja positsioneerimise süsteemi. Tavaliselt see on esitatud ühe-kahe mikrokiibid (füüsilise vormi), распаянными emaplaadi, on mõeldud rakendamiseks tegevuse ümberkujundamine andmevoo.

Paljud kaasaegsed kõvakettad iseloomustab toel erinevate transpordiliikide, sealhulgas DMA2, UltraDMA ja PIO. Et kasutada ära võimalused, nende valimise, on soovitatav alla laadida juht kontrollerid kõvakettad. Režiim DMA (Direct Memory Access) on kasulik, kuna see võimaldab märgatavalt leevendada kesk-protsessor on ARVUTI kui toimingute vahetada; seejuures töötleja on otsene seos liides arvuti. Erinevalt DMAmode PIO задействует protsessor saatmisel andmete liidese kaudu; kuid töötleja on otsene juurdepääs ram.

Mõnikord OS ei tunne töötleja kõvakettad isegi kui installitud draivereid. Selle põhjuseks võivad olla järgmised aspektid:

  • mehaanilised kahjustused. Kui silmatorkav või mõõnad elemendid гермоблока võivad olla deformeerunud. Deformatsioon kõige sagedamini kokku puutuda liidese moodul või kontakt koht kiibi kinnitamiseks. Kui vähesel määral kahjustatud seade võib remontida, kuid tööiga elemente on märgatavalt vähenenud. Tasub ka arvestada võimalus tehas abielu üksikuid elemente;
  • elektriline kahju. Töökorras riist-PC on suuresti sõltuv stabiilsuse pinge питанияРа süsteemi. Ületamise korral järsk või järsk pinge väljalülitamist, samuti elektrostaatilise lahenduse kaitsmed toiduahelas, elekter kiip või, halvemal juhul, cpu töötleja võib выгореть. Sageli kaitsmed remondi alla ei kuulu, ning vajavad väljavahetamist;
  • aegunud draiveri kontrollerid kõvakettad. Kui uuendada riistvara arvuti (või selle mõned osad) varem installitud programmid nõuavad värskendused sidumise puhul.
