技嘉主板超频BIOS设置

技嘉主板超频BIOS设置拿到主板的第一时间是到技嘉官网下载最新BIOS，然后在BIOS设置总页面按F8进入QFLASH，这个非常便利的刷新工具可以直接读取硬盘上的文件。

之前进入总页面的第三项Advanced BIOS Features，关闭CPU Enhanced Halt(C1E)及CPU ESIT Function两个INTEL节能技术，以及虚拟化等等。

然后进入总页面第一项MB IntelligentTweaker，第一部分是主要是CPU设置，这里我们可以看到E5200的倍频高达12.5，这里我们只需要把外频调整为320MHz，锁定PCI-E频率为100。

需要注意E5200的外频是很难拉升的，风冷的情况下外频极限大多只能达到350MHz 左右。

下面是DRAM设置，关于技嘉主板里的PerformanceEnhance设置，Standard被认为是冲刺频率所需的宽泛延迟，但很多技嘉主板上测试表明，这个设置无论调节成Standard、Turbo、Extreme，都不会对极限内存频率或者Everest内存频宽造成影响。

因为E5200的FSB是800MHz，没有好内存的话，超频E5200时会有一些难以取舍的地方。

MCHStrap使用默认的800strap比较容易把内存频率拉高，但是这个Strap设置下要求内存有1066MHz的体质，否则就只能超频至853MHz，或者放弃4GHz的主频。

而如果使用1066Strap或者1333Strap，会有更好的FSB/RAM搭配，但是内存超频性能会受到影响。

这里我们把MCH FrequencyLatch设置为200，分频选择333，实际达成的内存频率下方会显示出来，这个设定对超频用户比较贴心，笔者设定的内存频率为1066MHz。

把DRAM Timing修改为Manual后，内存时序设置就可以手动设置为5-5-5-15。

建议超频时手动修改内存小参，因为主板的AUTO参数设定得太紧，会影响到内存的极限频率。

HD_Tune_Pro参数含义[最新]

HD Tune Pro详解教程HD Tune Pro作为一款硬盘性能诊断检测的工具软件，它能检测硬盘的传输率、突发数据传输率、数据存取时间、CPU使用率、健康状态，温度及扫描磁盘表面等等。

今天，笔者在这就介绍一下HD Tune Pro V4.01汉化专业版的相关功能。

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =以下用笔者的一块西数160G硬盘的数据来做参考说明，具体数据以各位所用的硬盘为准。

图片为HD Tune Pro自带截图功能基准：浅蓝色曲线，代表的是HD TunePro检测过程中检测到硬盘每一秒钟的读取速率；爱生活爱顺网小点代表硬盘的寻道时间。

在右边还可以看到清楚的数据，传输速度的最小值，最大值，和平均值。

还显示了数据的存取时间，和突发数据传输率。

CPU的占用率。

选中“读取”然后“开始”就是。

“写入”一般是不可选的，只有一块还没分区的硬盘才能执行“写入”操作。

“快速行程”是选择要测试硬盘盘面的范围，或者就按自己喜欢呗。

话说笔者的硬盘真不咋的。

另外提一点，在“基准”测试里头改变选项中“块大小”会影响到测试的数据准确性，因此不要盲目相信某些网站所谓的硬盘评测数据。

参照不同数据出入挺大的。

信息：“信息”，顾名思义，硬盘的基本信息和支持特性都很详细的列出。

支持特性里头的项目是反映你硬盘的特性，不能被改动。

其中S.M.A.R.T特性下面会说到。

健康：笔者在这解说一下在“健康”测试中个参数的含义（仅作参考，因为原始数据的含义为硬盘厂家保密的，不同厂家可能不同）下面我们先大概了解一下S.M.A.R.T属性表：S.M.A.R.T.包含很多个属性，每个属性值只有两种含义，超过阈值和没有超过阈值。

一旦有属性值超过了阈值，表明“硬盘快不行了”。

每个硬盘的 S.M.A.R.T.信息中，都注明了这些属性的阈值，不同厂家的阀值是不同的。

Summary总结
Approved in July of 1992, TPC Benchmark C is an on-line transaction processing (OLTP) benchmark. 通过1992年7月,TPC C是一个基准在线事务处理(OLTP)基准。TPC-C is more complex than previous OLTP benchmarks such as TPC-A because of its multiple transaction types, more complex database and overall execution structure. TPC-C比以往更为复杂TPC-A OLTP基准如因其多种交易类型、更复杂的数据库,全面执行结构。TPC-C involves a mix of five concurrent transactions of different types and complexity either executed on-line or queued for deferred execution. TPC-C牵涉到一个混合的五个并发事务不同类型和复杂性要么执行延期执行在线或排队。The database is comprised of nine types of tables with a wide range of record and population sizes. 数据库由九种表与广泛的记录和种群数量。TPC-C is measured in transactions per minute (tpmC).TPC-C是以交易每分钟tpmC)。
