Pengantar OverClock

Overclock


Menurut yang kita baca di  Wikipedia bahasa Indonesia

Overclock adalah istilah teknologi informasi dalam bahasa Inggris yang mengacu kepada cara untuk membuat suatu perangkat untuk berjalan di kecepatan yang lebih tinggi daripada ketentuan pembuat perangkat tersebut. Prinsipnya adalah membuat performa lebih tinggi. Tetapi perlakuan ini beresiko menyebabkan kestabilan sistem yang berkurang sampai rusaknya peripheral computer yang dioveclock. Overclock biasanya dipraktekkan oleh para pengguna PC untuk "memaksa" periferal komputer bekerja diatas kemampuan standar yang ditentukan pabrikannya dengan tujuan akhir untuk meningkatkan performa kerja komputer.

Perangkat PC yang di-overclock sama saja dengan dipaksa melebihi kemampuan aslinya. Namun, overclock PC ini, selain membuat perangkat sistem menjadi tak stabil, dapat membuat kerusakan pada perangkat keras, terutama Mainboard, RAM, dan Prosesor.

Untungnya sekarang banyak perangkat keras yang dibuat dengan fabrikasi yang sudah handal untuk keperluan overclock, sehingga apabila dengan wawasan pengertian dan pengalaman overclock, itu kerusakan pada saat overclock dapat diminimaliasi.

Menurunnya tingkat kestabilan PC karena overclock bisa disebabkan oleh buruknya kualitas power supply unit (PSU), memori, dan atau mainboard. Untuk menghindari ketidakstabilan tersebut cobalah untuk mengganti power supply dengan kualitas yang baik dan cukup untuk menyuplai daya yang dibutuhkan oleh PC, dan perhatikan keadaan PC (Monitoring Hardware) selalu agar dapat mengetahui kesehatan PC kita karena hardware kita dalam keadaan ter-overclock. Memori dengan kualitas baik dan dapat membantu kestabilan PC, motherboard yang bagus dan memadai dengan bios yang lengkap. Untuk perangkat keras dengan kualitas memadai dan bagus untuk dioverclock tidak selalu berharga mahal.

Kerusakan perangkat keras karena dioverclock terutama disebabkan oleh panas yang berlebih untuk menghindarinya banyak cara yang bisa dikerjakan misalnya memperbaiki sistem aliran udara dalam casing, memperbaiki heatsink cpu/chipset/vga dengan cara lapping atau bahkan menggantinya dengan pendingin berkualitas yang sekarang banyak dijual di toko-toko komputer di Indonesia. Sistem pendinginan ada banyak macamnya seperti HSF (Heat Sink Fan) standar yang umum digunakan dimana pendinginan berasal dari kipas (Fan), Water Cooling, sampai yang ekstrem seperti menggunakan bong (Liquid Nitrogen [-280C] sampai Liquid Helium[-300C])dan dry ice atau peltier.

HOW-TO: Use your Gmail account as a personal file server

HOW-TO: Use your Gmail account as a personal file server


Selain yang kita tau Gmail account digunakan untuk mengirim dan menerima email.Ternyata Gmail account dapat kita fungsikan sebagai personal file server yang bertujuan menaruh file2 penting kita. Sehingga kita dapat membuka dilokasi mana saja tanpa harus kerepotan membawa flashdisk atau external drive.

Transfer
This is a fairly simple and useful trick to score yourself a gigabyte's worth of free online file storage. If you already have a Gmail account, you can use it as a central file server that is accessible from anywhere you can access Gmail. If you don't have a Gmail account... read on. We're going to install a shell extension that will allow you to mount your Gmail account as a virtual drive on your desktop, so you can perform basic file manipulation operations without having to go through the web-based interface. Drag and drop, batch copy, create folders and delete files as you normally would in Windows Explorer, and be able to access your virtual drive from virtually anywhere.

There are some limitations and caveats associated with this how-to: Gmail doesn't support files larger than 10MB, so you won't be able to store large movie files or anything, but you wouldn't be doing that anyway 'cuz it's illegal, right? Also, the Gmail drive shell extension only functions under Windows XP, but you'll be able to access and download any of your files via any operating system and browser combination supported by Gmail.

Be advised that this trick is completely unsupported by the Google folk and so may cease functioning at any time — particularly following upgrades to the Gmail service. As far as we know this isn't illegal (we actually read the EULA for you — that's love, people), but we can't guarantee Google won't go all RIAA on us and crack down on this app, either, so use at your own risk.

Also, it goes without saying that none of you would dream of using something like this to shuttle around any illegally-obtained or un-DRM'd music, right? 'Cuz that would make you a criminal, and we can't advocate that. This is only for personal use storage of your, uh, extensive Powerpoint collection, k? Buckle in and let's roll.

Ingredients



  • Gmail account

  • Gmail Drive shell extension

  • Windows XP PC

  • To access your files elsewhere, a browser that supports Gmail. Here's the official list:



    • Fully supported browsers:

      • Microsoft IE 5.5+ (Windows)

      • Netscape 7.1+ (Windows, Mac, Linux)

      • Mozilla 1.4+ (Windows, Mac, Linux)

      • Mozilla Firefox 0.8+ (Windows, Mac, Linux)

      • Safari 1.2.1+ (Mac)



    • Will work with Gmail's basic HTML view:

      • Microsoft IE 4.0+

      • Netscape 4.07+

      • Opera 6.03+






First up, download the Gmail Drive shell extension. The download page says you need to have Internet Explorer 5 or higher for installation; this just refers to the fact that Internet Explorer is infernally wed to Windows Explorer and you need a version of the Windows Explorer based on the IE5+ engine. If you're running Windows XP you should be all set with this. No need to actually launch that browser — we wouldn't conscionably recommend that to anyone.

Installation is as simple as running the Setup program. When the installer is finished running, it will tell you you can begin using Gmail Drive right away, but you may actually have to restart your machine before you can access the new drive. If you don't see it in the list of locations under My Computer, just try restarting. Otherwise, you should be seeing Gmail Drive showing up just any regular storage device would:

Gmail drive icon

Double-click the Gmail Drive icon, and you will be prompted for your login information:

Gmail Drive login prompt
Enter your deets and Gmail Drive shell extension will happily enumerate your files and log you in:

Gmail drive logging in

If you already have files stored in your account from attachments you've received, etc., you will see them in the Explorer window after you've logged in. Otherwise, if you have no files or if you've just created your brand spankin' new Gmail account, you'll just see an empty Explorer window:

Empty Gmail Drive window

Let's drag and drop some files into our new virtual drive. We'll choose some image files that we shot ourselves because, as far as we know, it's not illegal to copy these yet. Just open an Explorer window with some files you'd like to store on your new file server, select them, and drag and drop them into your Gmail Drive just as you would with any regular file transfer. You'll get a dialogue window with an animation involving a cute little phone that for some reason is sending a letter — some tribute to ye olde modems of yore?

Gmail Drive file transfer

Regardless, it means Gmail Drive is whisking your files happily away and posting them to your Gmail account. When the transfer is finished, you'll see icons for your files in your Gmail Drive:

Gmail Drive with files

Fabulous. Now — if you have another Windows XP machine you use regularly — your work PC, for example — you can just set up the Gmail Drive shell extension there and have Explorer-type file manipulation on that machine, as well. This could be a really handy solution for sharing files between your two locations. But since we already know how to use Gmail Drive, let's take a look at what happens when we log in to our Gmail account from a regular old web browser.

Go to the Gmail login and enter your account information:

Gmail login

When you log in, you'll see a number of new messages - one message per file you just uploaded. Messages corresponding to files that have been uploaded via Gmail Drive appear with a "GMAILFS" prefix in the header, following by the filename and the file size:

Gmail file view

Since we've uploaded images, we can view our photos right from within the Gmail interface:

Gmail message view

From here, we can forward the images on to friends, or download them to whatever machine we are on and have instant access to them at any time. Plus, we benefit from all the handy built-in features of Gmail itself; we can easily search for our files by name and tag them to organize them however we wish. All this from the installation of one simple and free utility.

So we know that a lot of you might find this handy, but you don't happen to have a Gmail account. Well, it's your lucky day, peeps, because we have a few invites to give away. Obviously we don't have enough invites for everyone, but we'll give them away on a first-come, first-served basis until they're all gone. Just make sure you use a valid email address when you post your comment, because that's where we'll send the invite to, dig? Don't say we never gave you anything.

GMail Drive shell extension


GMail Drive shell extension


Digunakan sebagai tambahan aplikasi yang menghubungkan antara komputer kita dengan shared drive gmail.

Sehingga apabila kita ingin memanage baik menambah, menghapus folder/file dapat secara langsung dengan menggunakan windows explorer bawaan.

GMail Drive shell extension

GMail Driveis a Shell Namespace Extension that creates a virtual filesystem around your Google Mail account, allowing you to use Gmail as a storage medium.

GMail Drive creates a virtual filesystem on top of your Google Gmail account and enables you to save and retrieve files stored on your Gmail account directly from inside Windows Explorer. GMail Drive literally adds a new drive to your computer under the My Computer folder, where you can create new folders, copy and drag'n'drop files to.

Ever since Google started to offer users a Gmail e-mail account, which includes storage space of 6000 megabytes, you have had plenty of storage space but not a lot to fill it up with. With GMail Drive you can easily copy files to your Google Mail Account and retrieve them again.
When you create a new file using GMail Drive, it generates an e-mail and posts it to your account. The e-mail appears in your normal Inbox folder, and the file is attached as an e-mail attachment. GMail Drive periodically checks your mail account (using the Gmail search function) to see if new files have arrived and to rebuild the directory structures. But basically GMail Drive acts as any other hard-drive installed on your computer.
You can copy files to and from the GMail Drive folder simply by using drag'n'drop like you're used to with the normal Explorer folders.

Because the Gmail files will clutter up your Inbox folder, you may wish to create a filter in Gmail to automatically move the files (prefixed with the GMAILFS letters in the subject) to your archived mail folder.

Please note that GMail Drive is still an experimental tool. There's still a number of limitations of the file-system (such as total filename size must be less than 65 characters). Since the tool hooks up with the free Gmail Service provided by Google, changes in the Gmail system may break the tool's ability to function. I cannot guarantee that files stored in this manner will be accessible in the future.













8 Nov 2007 update: Google is preparing for Gmail 2.0 and restructured their login. They will allow 3rd party tools to access an interim version for some time, but be prepared that GMail Drive may need to be updated again soon. Version 1.0.12 fixes the login, and now works with Google Apps accounts (hosted domains) too.







9 Jul 2008 update: A new version was released since some users complained that they had problems with login; please install the latest version 1.0.13 and reboot Windows.







26 May 2010 update: Fixed a login problem on Win XP. Now includes a Windows 64-bit version, and FileOpen dialog support has returned. Remember to reboot Windows after installation.







7 Dec 2010 update: Google stopped supporting Gmail UI=1, and moved to Gmail 2.0. GMail Drive was unable to save files, so a new version is needed. For older Gmail accounts you may need to disable the Buzz feature in Gmail to be able to see files.


Be aware that support for this tool may suspend at any time if Google decides to block its use.
