Tips to Help Increase uTorrent Downloading Speed

Are you getting bored at home and want to download some of your favorite audio and video content using uTorrent? Do you use uTorrent very often for downloading various interesting videos, audios, and game files available on the web? If yes, then you might be engaged in searching for some quick tips and tricks, which can help you boost the downloading speed of uTorrent. Some of the major reasons including a poor Internet connection, improper management of uTorrent, an inefficient BitTorrent client or many others can affect the downloadable speed of uTorrent.

In this article, you will read about the general tips and tricks that can make your downloading experience faster on uTorrent.

1. Check upload and download speed
The first and foremost thing is to check the maximum download and upload speed allowed by your ISP on your Internet connection. Generally, all the ISP's have pre-defined bandwidths, mentioned in their Internet plans, for both uploads and downloads. It is very obvious that your Torrent download speed cannot cross the limit, which has already been set by your ISP. Hence, before making any regret for your time-consuming download or writing negative reviews on the Torrent sites, you should always check the upload and download speed provided in your Internet plan.

To know about the upload and download speed, you can easily conduct an Internet speed test on your PC. These tests will display the results of the fastest upload and download from your end location to the defined test server location. It is recommended to choose closer test server while performing Internet speed test, as the TCP/IP degrades over distance. Speedtest.net, iWEBTOOL.com, Pingdom Tools, WebPagetest and many other speed testing websites are available for free over the Internet.

2. Choose a reputed Torrent search engineAlways choose a Torrent from a reputed search engine to ensure that it is clean, real and healthy. You can look for your desired content on reputed search engines by directly going to their websites rather than following a general search result on Google, which bring millions of trusted or fake links. One of the prime reasons behind trusting a well-known and reputed torrent site is that its library will have torrents of relevant content with reduced or negligible malware threats.

You can easily get torrents for movies, music, games and other files are available on the Internet under public (free and registration is not required) and private (paid and registration is required) search sites. While downloading these from the Internet, always be very sure not to click or download lucrative ads, scam links and toolbar downloads as they may contain viruses, which can infect your PC to an irreparable extent. BitSnoop, KATProxy, ThePirateBay, Torlock, isoHunt and ExtraTorrent are some of the reputed torrent search engines that carry a huge database of real and clean files.

3. Pick torrent with good trackers, seeds and peers
A good understating of the concept of trackers, seeds and peers will make the difficult task of picking a good torrent files an easier one. A simple principle about trackers, seeds and peers claim that a weak file paired up with less seeds and peers will get you a slow downloading speed while a file being paired up with more seeds and peers will bring a noticeable change in downloading speed.

Mostly, all popular torrent search engines display the number of seeds and peers attached to a particular file, just next to the actual size of the downloadable file. It is recommended to avoid downloading a file with zero (0) seeds as it may not have the content you are looking for or it is an infected one carrying higher malware threats.

On the other hand, the tracker plays an important role in getting the peers or seeds for your desired torrent file. A basic principle claims that having a good tracker allows you to utilize the full downloading speed irrespective of the client that you're using. Trackers are default downloads during downloading of the desired file in the target client, but it can be easily updated later for better results in downloading.

4. Limit your upload rate
Many of you share a lot of files online and overburden the upload rate available on your Internet connection, thus resulting in slower download rate. This setting is adjusted to an unlimited upload rate by default, so set it according to your needs as it is hitting your download rate too. Conduct a speed test, find out your maximum upload speed and then set Global Upload Rate in uTorrent according to your upload usage.

A considerable value would be setting the upload rate to about 80% of your maximum upload speed, as determined by the speed test. To get better results, you can also try a combination in upload speeds i.e. keep it high during the initial stage and then gradually decreasing it towards the middle of the download.

5. Pause or postpone all download running in background
It is recommended to either pause or postpone the downloading of the other files that are running in the background. As you know that these background downloads may consume a larger portion of your bandwidth resulting in slower downloading at uTorrent.

Always keep this in mind that if an Internet connection is only dedicated to your download, then the download process will finish faster. Ensure that no active download is running in the background and remember to close YouTube and other download managers, when uTorrent download is in process. Even if you have paused your uTorrent download for a while due to some reason, check that your computer is not downloading any automatic update or other downloads, when you resume your uTorrent download.

6. Increase the value of Max Half Open TCP connections
A Max Half Open TCP connection clearly specifies the number of connections a particular torrent client should attempt to establish at any given period of time. In most of the popular operating systems including Windows XP, Windows 7 and others, this limit is pre-set to 10. In order to increase the speed of uTorrent, you need to have a large number of simultaneous connections. You can easily change this figure by modifying the TCPIP.sys file in Windows and set it to a higher number.

After making the desired changes in TCPIP.sys file, also change the uTorrent's settings by using the following path:

options ->Preferences ->Advanced - >net.max_halfopen

Choose any number ranging from 50 to 100 and set it as a default number to get optimal downloading speed in uTorrent.

Above mentioned are some of the basic tips and tricks that can help you get faster downloading experience on uTorrent. Apart from this, upgrading your Internet plan, changing the position of router and adapters, connecting the computer directly to the modem or router instead of using Wi-Fi, changing your ISP, upgrading to the latest version of uTorrent and many other things can help you increase downloading speed of uTorrent. It is recommended to choose an Internet plan with no limitation on bandwidth to get effective results while downloading a large or heavy file using uTorrent.

Things Can Do to Prevent Windows 8 PC Crashes

Are you fed up of constant Windows crashes that force you to perform improper system shutdown to initiate the restart, which usually cause data loss? Not to mention about the frustration and constant disturbance that Windows crash brings along.

If your PC crashes consistently, that means something is seriously wrong with your computer. It is not probably a Windows 8 problem, because windows 8 runs stable on other computers.

Following are some of the quick tips that can help you in preventing the unexpected Windows 8 PC Crashes:

Check for Hardware conflicts: Many blue screen errors are a result of hardware and installation conflicts. All of your system's components consume IRQs (interrupt request channels) when installed, and every device requires its own channel to function properly. When two devices share the same channel and are used simultaneously, a crash may occur.

Go through your Device Manager, and look for any devices marked with a yellow exclamation point. These are the ones with issues, and can usually be fixed with a driver update. Just search your device manufacturer's website for the latest driver software, or, in a pinch, reinstall the offending hardware itself.

Does Your PC Has Bad RAM? Bad memory is many times the reason of blue screens and failed system boots. Fortunately, however, your RAM modules are some of the easiest components to check and replace.

First, use the software utility Memtest86+ to ensure if really your RAM is the cause of the problem. If errors arise, you next need to determine exactly which memory stick is to blame. To do this, remove all the sticks from your system-save one inserted in the primary memory slot. If the system boots fine and no errors are detected in Memtest86+, continue testing in the same fashion-one stick at a time, inserted in the primary slot-until the system fails to boot or Memtest86+ indicates problems.

Eventually, you'll nail down exactly which memory module is causing trouble, and then you can replace it with a fresh, clean stick (just make it fully compatible with your motherboard and other sticks of RAM).

Avoid Heating of the System: Computers usually get hot if used for longer hours. We know this from the loud fans bolted inside our desktops, and the alarming burning sensation we feel on our legs after using a laptop for too long. Everything inside a PC generates heat, and heat can cause components to become unstable and crash your PC. Indeed, computers are designed to crash as a last-ditch effort to protect their own internal components from permanent heat damage.

If you suspect your PC isn't effectively dispersing heat adequately, first check to make sure all your fans are spinning properly. If one isn't moving, or appears to be spinning abnormally slow, check its connections to make sure it's properly powered. If all appears fine, but the fan still isn't doing its job, it's best to replace it. Next, make sure that all of your PC's vents, grates, and filters are unhindered by dust, pet hair, and other gross materials that prevent proper airflow.

Run the Disk Defragmenter: Your hard drive can become a bit more fragmented-and unstable-every time you save a file, install a program, or delete something. Not only it slows down the hard drive, but it can also give trouble to your OS when trying to find necessary files to function. So your system will eventually give up and crashes eventually. Defragmenting your PC is as easy as pushing a button. Run the Disk Defragmenter in your System Tools every week or so to keep your files straightened out.

Check for Viruses: Malware and viruses are significant causes of blue screens. But, luckily, the solution is simple. Start up your trusted antivirus program, make sure it's up-to-date, and give your system the most robust scan available.

Starting in safe mode (press F8 while the computer is starting) is an easy way to go behind a virus' back to destroy it.

If the virus has disabled your ability to start up your antivirus software, then try restarting the PC in 'Safe Mode' by pressing 'F8' before the Windows logo appears. Safe Mode will disable any extraneous programs and drivers from launching, and allows just the core operating system to load. Once in 'Safe Mode,' you should be able to run your antivirus program, and complete a thorough scan from there.

If you take care of the aforementioned things, then you can actually avoid the crashes in Windows 8, blue screens, failed boots or frozen system. All you need is to be bit alert and protective towards your Windows 8 to run it smoothly.
