The present invention is the operation situation by monitoring display card assembly, the unusual condition that allows the user understand and solve display card smoothly and taken place.In addition, when unusual condition took place, display card monitoring establishing method of the present invention can inform how the user solves abnormal problem or initiatively adjust the related setting value, with real-time processing unusual condition.
Please refer to Fig. 1, illustrate process flow diagram according to the display card monitoring establishing method of a preferred embodiment of the present invention.At first enter step 102, regularly detect the display card assembly.For example: for the running situation of assemblies such as the drawing chip on the display card, storer, fan, can utilize the monitoring means (for example monitoring IC) that also is arranged on the display card regularly to monitor, its monitoring project can be drawing chip voltage, bus voltage (for example AGP voltage), drawing chip temperature, memory temperature, rotation speed of the fan etc., and the user can set every (for example per 5 seconds, 10 seconds, 1 minute one period set time simultaneously ...) startup this method.
Then in step 104,, judge whether to take place unusual condition at the data that detected.Learn when testing result unusual condition does not take place, then enter step 112; When unusual condition takes place when, in step 106, transmit abnormal information, notify user's interface that testing result is shown by driver.
In order more to clearly demonstrate the processing of unusual condition, at first, please refer to Fig. 2, illustrate the process flow diagram of monitoring voltage degree of stability among Fig. 1.Because the drawing chip need obtain a large amount of and stable electric power from bus, can bring into play maximum usefulness.Therefore, the voltage-regulation coefficient monitoring can allow the user know that how much electric power is bus have output to the drawing chip, stably operates with the calculating function of guaranteeing the user.In step 202, monitoring means detects drawing chip voltage value and bus voltage value, and calculate the gap of drawing chip voltage value and bus voltage value in step 204 after, enters the judgement of step 206; When gap during less than a tolerance, then the end voltage degree of stability detects, when gap greater than tolerance, then enter step 208, send electric voltage exception information.
In addition, in Fig. 3, illustrate the process flow diagram of monitoring rotation speed of the fan among Fig. 1.In step 302, monitoring means detects the fan voltage value of fan, and conversion according to this obtains rotation speed of the fan in step 304, in step 306, when judging rotation speed of the fan between a normal range, finishes the rotation speed of the fan monitoring; When judging that rotation speed of the fan exceeds this normal range, then enter step 308, send the fan abnormal signal.
When and heat dissipation design unsettled situation, especially computer housing overheated for fear of display card is not good, cause display card impaired easily, therefore need be by temperature detection to carry out overheating protection.Step 108 as shown in Figure 1, detecting unit is judged after obtaining a temperature detection value, when temperature detection value non-greater than a critical value, enter step 112, after temperature detection value is greater than this critical value, except informing that user's temperature is too high, in step 110, can initiatively reduce the use clock pulse by driver, temperature is reduced naturally; And traditional monitoring mode is only warned monitoring project and abnormal state of affairs occurred when unusual condition takes place, and BIOS can't initiatively carry out follow-up work of treatment according to monitoring result.The object of temperature detection of the present invention can be drawing chip or storer etc., and temperature detection value can be the temperature detection value of drawing chip or the temperature detection value of storer etc., and like this, the overheated drawing chip or the temperature of storer just are minimized.
In addition, because display card is to couple by bus and motherboard, motherboard has a central processing unit (Central Processing Unit; CPU), can be via reading CPU usage in step 112, and in step 114, dynamically adjust drawing chip clock pulse and storer clock pulse on the drafting card according to CPU usage, and afterwards, return step 102, repeat display card monitoring establishing method.
With the example that is classified as that present CPU usage was adopted, can be divided into 0-20%, 20%-40%, 40%-60%, 60%-80% and 80%-100% five grades, therefore preferably drawing chip clock pulse is divided into five grades, similarly also the storer clock pulse is divided into five grades, can be according to the grade of CPU usage, the use clock pulse of drawing chip and storer is set at the grade identical with CPU usage.For example: when CPU is idle state (idle), that is CPU usage is when being in first order 0-20%, and the setting meeting of drawing chip clock pulse and storer clock pulse is adjusted automatically and is all the first order, to reduce voltage and to reduce temperature; On the contrary, if when computing machine is in high utilization rate,,, the setting of drawing chip clock pulse and storer clock pulse is adjusted automatically be all level V just can carry out dynamic overclocking as playing 3D computer game.Compared to traditional " fixed formula frequently " overclocking method, the present invention must not set up the work time pulse of adjusting display card on their own by the user, and can be along with the difference of the performed application program of computer system, and when needs are high-effect, initiatively carry out dynamic overclocking, display card automatically by overclocking to " the highest tolerance frequency ", the display card that therefore can avoid causing because of misoperation damages, and can not need when the most high-effect again simultaneously, the automatic frequency reducing of display card, prolonged in the display card life-span.
