To choose satisfactory mainboard

To choose

The foundation as the overall structure of computer, mainboard choose to be is important, many friends in since a lot of books and periodicalses have seen mainboard the article chosen , but the rapid speed of weed out the old to bring forth the new and the renovation of product, make us can not apply mechanically regular formula, moreover various mainboard kinds are numerous, how do you then can choose the mainboard with higher a cost performance easily?
Following summary happens following
The battery
Battery is set up to maintain the operation of CMOS data and clock. " fall news " denote battery to sink news , can not maintain CMOS data, even barrier machine is rear, clock does not be also gone to. Choose , observation battery whether rusty, leakage liquid, if get rusty , may change battery; If leaking liquid, serious, may cause piece mainboard to discard because of corrosion.
2, chip produces
The speed of mainboard not only depends on the speed of CPU , at the same time also depends on the performance of chipset on mainboard. If the production of each chip date differs is greater, will be careful. Generally speaking, time differs the unsuitable overall performance that exceeds 3 months and will influence mainboard otherwise.
3, expand
Generally speaking, ISA development groove is easy to observe more than PCI development groove. Method is to observe the location shape of the spring flat of groove hole first carefully after, insert ISA card in groove again pull out , the spring flat location shape that observes current groove hole whether and is originally identical, if have greater deviation, explain that the spring flat elasticity of this slot is not good, quality is lacked comparatively.
4, weight
First, see mainboard thickness, two mainboards are compared , thick person is advisable. Observe the number of plies of mainboard circuit board again and wire layout system whether is reasonable. Take mainboard , separate mainboard as light source sees , if be able to observe the component of wire layout of another surface, explain that this mainboard is double-deck board. Otherwise mainboard is 4 layers of or multilayer board, when choosing , should choose 4 layers of or multilayer board. Is other, whether wire layout is reasonably smooth, will also influence the electrical performance of piece mainboard.
5 , shake
Careful observation each group jumps line whether is empty to weld. Start after, light wave to jump line, see personal computer whether make mistakes , if have to make mistakes , message explains to jump , have loose line and unstable performance, this mainboard is not being chosen.
6, software
Choosing SPEED series to measure fast software and SST series measure fast software. About the use of this two series softwares, the friend that is interested may look up relevant information independently.
Certainly, when choosing mainboard, the mainboard standard of every user for own requirement is not identical, specific each may need according to own economic condition and work choose. When choosing , excluding above quality still notice brand and the manual of mainboard besides the coherent law distinguished, if your hardware knowledge is not very sturdy, suggesting to do not want purchase those no manual or handwriting does not settle to have no the mainboard of remarkable brand. Is other, is surefire, best talk with manufacturer when purchasing , allow to send back goods.
