Nvidia Tegra 3 Chip

The Tegra 3 is one powerful little chip, featuring four cores plus a fifth “power saver” core to create what Nvidia is calling Super 4-PLUS-1™ which provides power when needed by enabling and disabling cores based on workload. The chip is made to deliver console quality gaming and superior HD video.
If your not familiar with this chip, this is the work horse behind the new Google Nexus 7.

The big thing I personally see with this chip when going through all of its specs are the all the power saving features and efforts to improve overall responsiveness. Mobile devices like the Nexus 7 have been noted for smooth performance, Nvidia attributes the smooth feel to its DirectTouch™ architecture that is designed to improve touch responsiveness by handing a portion of the touch processing onto the Tegra 3 processor.

The overall feel of the device has long been a deciding factor for me when choosing mobile devices. It really takes alot away from the experience even when there is a small amount of lag when navigating.

The Tegra 3 is also inside many other devices including the Acer Iconia Tab A510, Asus Transformer Pad TF300 and the Toshiba Excite 10 Tablet.

Solid State Drives: Why You Need One

As we go over the long list of specs on a new computer we usually gloss over our storage options and focus more on processing power and memory, and for good reason as our storage options haven’t really changed much over the years.

Now, a new option has arrived on scene, Solid State Drives (SSDs). Solid State Drives are a whole new beast and they have a lot to offer. SSDs are comprised of multiple flash memory chips that are all connected together.

Being comprised only of chips means that Solid State Drives contain no moving parts and unlike the Hard Drives we are used to using, are completely silent when in operation. We can finally say goodbye to that grinding sound we hear everytime our drives spin up, but to their credit they have become much quieter over the years.

What makes this technology so amazing is its speed. SSDs read and write data at such blazing speeds that on some systems, can make Windows load faster than the animation that plays during boot up. Load times in games are reduced drastically and content loads much faster though out the whole system. It really shows how much of a bottleneck our old Hard Drives were.

However, it took me a while to build up the courage to buy one and put all my data on one these new drives. When SSDs first started to pop up in stores there were many problems with the firmware installed on these drives, some of which could result in a complete failure of the drive itself. Another issue was price, it was hard to justify the cost per GB. SSDs that have been on the market for a while now and a lot of manufacturers seem to have worked out alot of the bugs that plagued early SSDs. SSDs are becoming much more popular, in fact SSDs are now being installed in the new Macbook Pro (retina), and performance gains are obvious

Prices are still not nearly as cheap as the old hard drives but there are many deals going on right now as companies and retailers are trying to push the world towards this new storage option. Still think its a bit to pricey ? No need to worry, as consumers buy more of these drives I expect to see prices drop again.

I did remain skeptical for a long time about how much performance gain I would really see until I just jumped in and bought one of these drives. If your curious as to how my experience was, let me just say that once you buy one of these you will probably never go back.

Prision for RuneScape Robbery

RuneScape

Two University Students David Emani and Jonathan Dokler were robbed at gunpoint of 4.7 billion RuneScape coins by a another student named Humza Bajwa.

At first, Humza attempted to buy the coins from Emani using counterfeit money but he was quick to call him out on the fake cash.

Once he realized Emani wasn’t buying his scam, Humza pulled out and air pistol, that looked much like a real gun, and pointed it to Emani’s head.
Humza then ordered Emani to call Dokler to have him transfer the coins.

Even though the gun was fake and the property stolen was virtual, Bajwa was arrested by local authorities and charged with second-degree robbery and grand larceny. The stolen coins could be valued over $3,000. Bajwa faces up to 15 years in prison for his actions.

How To Protect your Wi-Fi Connection

You might be surprised to see just how many people are using unsecured Wi-Fi connections in their homes. I see this all the time and am quick to help them lock up their connections. Keeping your Wi-Fi connection secure not only improves your speed by keeping the neighbors kid from gaming on your internet connection while you try to download the latest movie but also keeps your private data from being intercepted as well.

Here are a few good security tips to follow.lock and keys

Make sure you change the default user name and password to your router. Many routers use a default user name and password that is universal and if you don’t change it anyone can get access to your router. I have actually seen scenarios where someone will encrypt their Wi-Fi connection only to leave their router credentials at the default. This is counter productive as a would be internet thief could simply log in and change your security settings to gain access to your network.

Enable WEP or WPA. WEP and WPA are technologies that will encrypt the data sent over your wireless network. When choosing a security type be sure it is comparable with all of your devices. If you set up your encryption but your old iMac wont connect to the network even with the right password, you might need to change to a different encryption type such as WEP.

MAC address filtering. Any device you use to connect to a wireless network will have a physical address or MAC address associated with with it. Your router keeps track of each device connecting to it by using its MAC address. Your router or access point will have features in it that allow you to only provide connectivity to certain MAC addresses you list.

Locking down your Wi-Fi connection is simple and can be done fairly easy. Many routers and access points these days come already encrypted and have software to help you along.

Beginners Guide to PC Building: Getting Started

by 1 Comment

Have you been wanting to build your own PC from scratch but not sure where to start? This Beginners guide will help you get started and make sure you prevent major mistakes.bluetintedMicrochipArt

So, if you have done any research up to this point you will probably have noticed the shear amount of combinations there are when it comes to building your own. Selecting the right motherboard and cpu combination, memory, power supply, and case can all seem a bit overwhelming but this process can be simplified with a bit of planning and remember it is also about having fun!

So why build your own PC?

Personally, building a custom PC to me is my version of working on the hot rod in the garage. The customization and tweaking are all part of the process I enjoy. It also gets you closer to the technology and allows you to really appreciate and understand it from a perspective that otherwise might not be so clear. Ultimately, the feeling you get when it all comes together is worth it alone.

Getting Started

The first thing you really should do is decide what you want out of your build by asking some basic questions. What is this build for? gaming,video/photo editing, multiple OS machine, server, media hub. Once you decide the build purpose, you can narrow down your choices a bit. Another Consideration here is budget, how much are you willing to spend? Look around for different retailers and find the best deals. Another important thing to consider here is brick and mortar stores vs online. There are distinct advantages for both here but remember some stores will price match. Also consider the need to return/exchange a product, if a local store can price match go there, why wait a few days to get something exchanged or refunded when you can drive right to the store?

The CPU (AMD or Intel?)

This is the first real fork in the road here and an important decision to make early on because your motherboard selection will only work with one or the other. Both AMD and Intel make great chips, each company offers differing performance for price and ultimately the decision is entirely up to you. I wont try to push you in either direction here as your decision is more about the type of CPU rather than the brand.

CPUs are generally broken down into groups based on the amount of cores, operating frequency (GHz), and Socket. There are other factors to consider as well such as power consumption and cache. Choosing the series of processor should not be difficult but you should put some thought into your decision really think about your computing needs and what your trying to accomplish.

The MotherBoard

After you have chosen your CPU you can select the motherboard you would like to use. There are a few features to consider when choosing a motherboard like how many drives your planing on having and what size of motherboard you want to use. Motherboards come in many form factors, Standard ATX, Micro ATX, Mini ITX, and Nano ITX. The two most common here are Standard and Micro ATX. Check over the specs on the motherboard and make sure it meets your I/O needs (usb ports, Firewire, optical,bluetooth). Think about how many SATA connectors you will need and what speeds they operate at, typically 3Gb/s and 6Gb/s for SATA.
Factor in how much memory can the motherboard support and how many PCIe slots are available and if it supports multiple GPUs what type of multi-GPU support it has (NVIDIA SLI Technology or AMD CrossFireX Technology).

The big thing to take away from choosing a mobo/cpu combo is making sure things are compatable.

*USB 3.0 is becoming more common and is featured on many new motherboards, however many only come with a few 3.0 ports and the rest 2.0, so take note of how many you need and how many are included.

The Case

Some Considerations-

-Size-

The wonderful home for all of these components needs to be large enough to support all of the of the hardware you plan to install inside it. This may sound like a no brainer but I know that many people have later on realized that they wanted the latest and greatest graphics card only to find they dont have enough room, and some may have even gone to great lengths to make it fit ie.(dremel tool). So make sure you you give your self enough room to work with for what you need and what you may want in the future.

-Air flow-

Make sure the case you choose has adequate airflow design that makes sense. Believe me, you would think that this would be considered more when manufacturers make these cases, just trust me here when I say not all cases are created with intelligent airflow design.

-Management and other Features-

Most cases will have nice features like drive bays that you can simply slide and lock into place and wire management areas to keep your wires from becoming a rats nest. Check to see where headphone jacks and USB ports are located.

Power Supply

The Power Supply you choose should have all the nessesary power connectors you need. Remember each drive you install needs power, each graphics card you install needs its own power connector. Wattage will be determined by the amount of devices needing power and if you plan on installing a graphics card you will see a minimum requirement for wattage right from the GPU manufacturer.

*It is better to have a little more power then barely enough, you don’t want to stress your system and its components.

*Newer drives use SATA power connections, older drives use Molex connectors.

Memory

The type of memory or system RAM you install will depend on what is compatable with the processor you chose. Check the memory guidelines for the processor you choose. Once you find the right type of RAM, choose how much you want to install.

*If you are running a 32-bit version of Windows then you can only utilize up to 4GB of RAM, anything over this amount will not be recognized by your system. To gain access to memory capacity larger than 4GB you will need a 64-bit version of Windows.

Graphics

If you’re planning on gaming or doing other demanding video tasks then you will want to get a high end graphics card capable of handling lots of video data at once. The brand you go with is less important unlesss you are planning on using multiple graphics cards at once, in this situation need to make sure your motherboard supports the technology you’re trying to use. SLI and Crossfire are the two major communication protocols used in Nvidia and AMD graphics cards. Basically, it is the technology that allows multiple video cards to work together.

Storage and Media

Choose how much hard drive space you will need and what type of optical media you want to use. Plan on watching movies? Grab a blu-ray drive, preferably one that also burns blu-ray discs.

Another popular choice for storage are solid state drives or SSDs. SSDs are much much faster than standard hard drives and cointain no moving parts, so they are silent when running. This is a great performance boost in any system but it comes at a price. Many SSDs sell for about $1.00 per gigabyte, which is much more expensive then the old hard drive.

Wrap Up

This should hopefully help guide you through the first part of your pc building experience. I will be adding more parts to this guide in the future. You can really get into the details of each of these components more on your own as you learn more about the hardware that powers our computing experiences these days.
