M12e说明书

M12e说明书隔壁刚评测了ROG系列中旗舰级配置，亲民级价格的ROG Strix Z490-E Gaming，但很多朋友肯定都在喊别瞧人不起了，别和我们ROG用户谈钱，要谈就谈信仰，来块最好的！别急，今天这块要评测的这块华硕旗舰级主板ROG MAXIMUS XII EXTREME(以下简称ROG ROG M12E)，保证能让各位希望得到至尊体验的信仰玩家满意。

不得不说旗舰级的主板就是不一样，不仅包装更用心了，刚打开盒子，把主板和配件都陈列出来就能让人感受到配置拉满的愉悦感。

比一般主板更大的盒子里满满当当都塞满了各种配件，除了常规螺丝和接线之外，其中还有一张搭载了华硕专利技术的DIMM.2接口的拓展卡，可以插M.2的SSD获得更强的性能提升，和一张支持40Gb/s双向传输的雷电3协议接口拓展卡，这两张拓展卡到底有什么用等下会提到。

再看这块重量能比的上一台小机箱的真·大主板，ROG ROG M12E采用的是E-ATX大板，所以比一般的ATX搬还要大上一圈，达到了30.5cmX27.7cm级别的大小，更大的主板带来的当然是更加扎实且豪华的用料和更多功能丰富的接口，众多接口还采用了横置式设计，保证安装走线更加便利的同时，也能提升装满配件时主板的美观。

主板正面有一块全覆盖式散热装甲，多组超大的散热鳍片搭配隐藏式的U型散热管和高效散热贴，对于硬件满载运转时的散热应该有非常明显的帮助；正面还搭载了一块2英寸的LiveDash OLED面板，可显示CPU温度、频率、风扇转速、故障诊断信息等，甚至支持显示个性化图文信息；而翻到主板背面，我们可以看到背面依旧被一块用料厚实的散热装甲覆盖，但在处理器底部却开了一个窗口，方便我们装配散热器的同时，对于CPU 散热也不会产生负面影响。

这正面背面都多加了用料相当扎实的两块大铁板，ROG ROG M12E能不重吗？然而扎实的用料不止是铁块用的多而已。

在供电方案上，ROG ROG M12E采用了最顶级的16个英飞凌TDA21490供电模组，每个可处理高达90A电流，要知道上一代的旗舰M11E用的还是60A每相的供电，再加上双8Pin ProCool II供电接口用特制实心接针，确保与EPS 12V电源线连接更充分，让我们在知道这代用料扎实的同时，也不难想象10代CPU的吃电能力会有多么怪兽；ROG ROG M12E还采用了比传统相数倍增设计供电更科学且稳定的整合式供电架构，可以让各个EPS12V电源线都能平均供电并有效减少发热量。

富士通 PRAID EP400i EP420i 存储设备控制器数据表说明书

Data SheetFujitsu PRAID EP400i / EP420iRAID Controller SAS 12Gbit/s 1GB or 2GB cache based on LSI MegaRAID® for internal storage devices The RAID architecture (Redundant Array of Independent Disks) combines multiple storage devices, including hard drives and NVMe devices, into a single logical unit. Redundancy data is generated from data segments (barring RAID 0) and distributed across the devices. Consequently, operating systems interact with this collective array rather than the individual devices. The core purpose of RAID is to enhance data availability, reducing potential disruptions from storage devices failures. The effectiveness of a RAID setup largely depends on the RAID controller in use.Choose Fujitsu RAID controllers for a blend of modern technology and proven experience,providing the data protection that businesses need today.PRAID EP400i / EP420iThe Fujitsu RAID ControllerPRAID EP400i with 8ports sets new speed and data security standards for internal storage drives. The RAID stack isbased on the LSI MegaRAID® and offers high data throughput, a comprehensive fault tolerancefunction and user-friendly management options.Moreover, the Controller management is integrated seamlessly into the Fujitsu server managementconcept. All controller functions are supported by the Fujitsu ServerView RAID Manager. The PRAIDEP400i is designed for backward compatibility with 3Gbit/s SAS as well as with 6Gbit/s and 3Gbit/sSATA hard drives. Regardless of the drive speed, itdelivers significant performance improvements in both read and write applications. Due to the support of 64-bit addressing, a robust set of RAID features and demanding error tolerance functions the controller provides high RAID performance and data availability. Powerful online management service programs (Fujitsu ServerView RAIDManager), which are simple to operate and quick to install, provide the administrator with unparalleled flexibility and access to the arrays. The RAIDcontroller supports all of the important RAID levels including RAID 6 and 60. The optional flash battery backup (FBU) combined with TFM module ensures the integrity of the data stored in the cache on the RAID controller in case of a power outage. In this event, the data will be copied to a non-volatile flash memory (TFM). The FBU provides a low-priced alternative to an uninterruptible power supply (UPS) and, when compared to battery backup up units (BBU), enables a long-term, secure store ofdata and better serviceability. Always select FBU and TFM module in combination.The Advanced Software Options in combination with Solid State Disks in front of HDD volumes can create high-capacity,high-performance controllercache pools, depending on the load profile.

对笔记本外观参数及配置的描述的英语作文

对笔记本外观参数及配置的描述的英语作文When choosing a laptop, there are several key factors to consider, including its appearance parameters and configuration. In this essay, we will delve into these aspects in detail.First and foremost, let's examine the external appearance parameters of a laptop. The laptop chassis material plays a crucial role in determining its durability and aesthetics. Common materials include plastic, aluminum alloy, and carbon fiber. Plastic chassis are lightweight and cost-effective, but may lack the premium feel of more expensive materials. Aluminum alloy, on the other hand, offers a sleek design and enhanced durability, but often comes at a higher price point. Carbon fiber is a relatively newer material in the laptop industry, known for its lightweight nature and excellent strength. It is often utilized in high-end, luxury models.The laptop's size and weight are also important appearance parameters to consider. The screen size typically ranges from 11 to 17 inches, with 15.6 inches being the most common. Smaller screens offer enhanced portability, while larger screens provide a more immersive viewing experience. Weight is another critical factor, as it directly affects the laptop's portability. Ultrabooks, designed for optimal mobility, generally weigh around 2.5 pounds, whereas gaming laptops can weigh well over 7 pounds due to their robust hardware.Moving on to the laptop's configuration, the processor is a fundamental component to evaluate. Intel and AMD are the leading manufacturers of laptop processors. Intel offers a range of processors, including the budget-friendly Core i3, mid-range Core i5, and high-performance Core i7 and Core i9. AMD processors, such as the Ryzen series, are known for their superior multi-threading capabilities and competitive pricing.The processor's clock speed, measured in gigahertz (GHz), determines how quickly the laptop can execute tasks.Another crucial aspect of laptop configuration is the RAM (Random Access Memory). RAM size determines the laptop's multitasking capabilities, allowing it to handle multiple applications simultaneously. Most laptops come with 8GB or16GB of RAM, but higher-end models offer 32GB or even 64GBfor professionals with demanding workloads.In terms of storage, there are two main options:traditional hard disk drives (HDD) and solid-state drives (SSD). HDDs offer larger capacities at a more affordable price, making them suitable for storing large files. However, SSDs significantly outperform HDDs in terms of speed,enabling faster boot times and application loading. Therefore, laptops equipped with SSDs provide a more fluid user experience.Furthermore, it's essential to consider the laptop's graphics card (GPU), especially for gamers, graphic designers, and video editors. NVIDIA and AMD are the prominent manufacturers of dedicated GPUs. GPUs handle complex graphics calculations, enhancing gaming visuals and accelerating rendering times. Mid-range and high-end laptops often feature dedicated GPUs, while ultrabooks and low-budget laptops typically rely on integrated graphics processors (IGP).Lastly, the laptop's battery capacity is a critical parameter to examine. A higher milliampere-hour (mAh) rating indicates a larger battery capacity, resulting in extended usage times. Laptops with energy-efficient processors and optimized power management systems tend to offer longerbattery life.In conclusion, when choosing a laptop, one must consider the appearance parameters and configuration details. Thelaptop's external appearance, including chassis material,size, and weight, impacts its durability and portability. Configuration aspects, such as the processor, RAM, storage, graphics card, and battery capacity, determine its performance capabilities. By carefully reviewing these parameters, individuals can find a laptop that meets their specific needs, whether it be for work, entertainment, or creative endeavors.。
