It has the same GK 110 lineage in the Titan DNA as the GTX Titan and the GTX 780. It also has full 2,880 CUDA cores that is 25 percent more than GTX 780. It is clocked in 875 MHz base clock and 928 MHz boost clock. These additional CUDA cores and higher clock speeds complements to the 3 gigabytes of DDR5 memory at 7 gigahertz 384-bit bus.

Video Card Shopping Tips – How to look for the best Graphics Card?

Are you shopping for PC graphics card? You will be bombarded with misinformation. Mostly, people are intentionally misleading you. They just do not understand what they are selling but you are the one who ends up being burned. The biggest misconception is that you cannot compare performance by looking at specifications.

Electricity, Voltage, Current, Power, AC and DC - Tutorial

I am going to start with a little bit of history to give you little basic knowledge to understand different types of electricity – AC and DC. Electricity has been discovered a long time ago. It was discovered apparently many years BC in the form of static electricity. They realized when they touch a catfish; there was a shock on their body. Therefore, that is when the notion of electricity apparently started coming about. 

How to Install an Intel LGA1156 or LGA1155 CPU Processor?

This time, we are going to show you how to install your Intel CPU using LGA 1156 or 1155 as fast as possible. Either the first step is to find a little golden triangle on your CPU and align that with the little plastic triangle on the cover, or once you remove the cover, the metal triangle that is on the CPU socket itself.

RAID 0, RAID 1, RAID 10 - Things you need to know

In this post, we are going to tell you all you need to know about Raid 0, Raid 1, and Raid 10 in a more comprehensible way. You have probably read about RAID somewhere, but do you know what it really mean? It stands for redundant array of inexpensive disks and it means using multiple drives or disks to achieve better performance and/or better reliability.

How to Build a Retro Gaming PC (2001)?

On our retro series, I will talk about how to build the ultimate gaming computer, not this 2014 but for 2001 and below games. There are some very interesting marketing data on new PC purchases during that year, which shows that most PC upgrades for consumers are driven not by the grownups in the house but by the kids who want a more powerful gaming machine. 

How to Choose and Install Cooling PC Fans?

On today's blog post, I am going to show you how to determine what kind of fans are compatible with your case or cooler, and how to install them. Figuring out which fan is compatible with your case? If you have an aftermarket case, it is a snap. Check the manufacturer website, look on the side of the box, or check the manual. It will tell you which mounting points correspond to which fan sizes.

How to choose PC Motherboard Sizes (ATX, mATX, eATX, XL-ATX, and mini-ITX)?

Let us get things off with ATX, stands for advanced technology eXtended, a component compliance with the standard tells us that it will be physically and electrically compatible with other ATX components like computer cases and power supplies. Now become most desktop computers use ATX, which is what we are going to focus on, but there is other stuff out there anyway. 

How to SLI and Crossfire in one PC?

Shopping for graphics card is tough. AMD has all kinds of technologies like Crossfire, True Audio, Mantle API, great OpenCL performance, and HD 3D while NVidia has SLI, G-Sync, 3D Vision, PhysX and Game streaming. No matter how much you spend on your computer, you can't have all these things at the same time - or can you?

What is the safe PC Temperature?

This is a question I have been asked a hundred times and based on a quick Google search it looks like there are quite a few other folks who want the answer. How hot can my PC run before it is not safe anymore? We will start with why you would care how hot it runs. Some lots of reasons and high temperatures can cause all kinds of step in semiconductors. It increases the electrical resistance, reducing efficiency, it can speed up the degradation of electrical pathways within the component allowing errors that cause data corruption, and it can even, if the proper safeguards were not in place, cause low-temperature solder that is sometimes used to completely melt.

Single Rail vs Multi Rail PC Power Supplies - Which is better?

What is a single and multi rail PC power supply? What is the difference? Do you need to care about it? At the most basic level a power supply converters AC from the wall to DC current for your CPU and other components to use and then an octopus of wires that carry 12 volts, 5 volts, and 3.3 volts of current to your graphics card motherboard. However, how do rails enter into it? 

How to Configure SSD as boot drive plus HDD as storage drive?

We have all talked about SSDs and how great they are as your boot drive but I have had a ton of people asking me how to use an SSD for my boot drive and configure it to boot to that particular drive and access a mass hard drive for my storage and my larger programs. Today, I am going to show you guys how to do that.

How to upgrade Mac Mini 2006 (mac mini 1,1)?

The first question is, "Can you upgrade your Mac Mini 2006?" The answer is YES.

Is it worth to upgrade? Well, not much but at least you can increase the processing power of your Mac Mini and extend its usability to the needs of modern computing.

What is Hyperthreading and what are its Benefits?

Hyper-threading technology from Intel has been on their computer processors for over 10 years and yet much same as the elusive Fox, most people know very little about what it says. Let us start with an analogy. Let us say I am a CPU and I am trying to process food, or eat as some people call it. I can only do as much eating as one mouth can do if I could add more mouths than I could process more. This is what multi-core processors do but due to cost constraints among other things, it is not always possible to take that approach, so I have got just one mouth I can use my hand to pick up the food, bring into my mouth, then grab another bite while my mouth is busy. If I finished chewing before my hand is ready to deliver me more food, however, then my mouth is just sitting there doing nothing. If only I could use two hands to prepare food for my mouth then even though my mouth cannot actually work any faster I would not waste any time. Oh wait I can do that. 

What is Bottleneck or Bottlenecking on your PC System?

A BOTTLENECK occurs when there is some restricted element holding back the performance that could otherwise be achieved. Fluid flows much slower through the neck of the bottle than if the neck does not excess. Another word for a bottleneck is the CHOKE POINT.

Let us start with a couple of examples. In a vehicle, the traction between the tires and the road is important for optimal power delivery between the engine and the road making the car move forward. Now an example where traction would be a bottleneck if your engine were so powerful and then you go to accelerate, the wheels just spin. Now at high speeds a wing could improve traction by using airflow to force the rear of the car down towards the road. This can alleviate that bottleneck. That sounds great! 

How to choose the Right PC Power Supply (PSU) for your system?

A computer power supply is almost as mysterious as the phrase, “I'm fine just leave me alone.” I mean, what does that even mean? If I actually leave you alone to go play video games, will I be making a huge mistake and like pay for it later. I mean if you were fine wouldn't you want to talk to me like you normally do and if you're not fine when it blows up later, will it be your fault for not communicating clearly or my fault for not understanding? Please tell me what you want.

Anyway, while I am not qualified to help you understand women, I can help you choose the right wattage of power supply for your PC.

When to Upgrade your RAM or Computer Memories?

You might say, “I need more RAM that will make my computer go faster.” Wrong! More RAM can improve performance and there was a time when it usually would but those days are gone. Modern computers, even ones that are two to three years old, often have enough RAM for the basic tasks that users want to perform.

So how would you know if you do not have enough memory causing your system to slow down? Check out the Performance Monitor in task manager (CTRL+ALT+DEL on Windows).

How to convert Laptop into Desktop PC?

I will tell you how I built a desktop computer using the motherboard from an old laptop that had a cracked LCD and a broken hard drive. I used Acrylic Alumina thermal adhesive to paste a big piece of aluminum on top of the CPU. It is actually glued on top of the heat pipe that is cooling the CPU.

Do you need more Pixel Density (PPI) or Retina?

Resolution is often the only specification quoted when referring to the finest of a digital image but there is actually much more to it than that. A five-inch 1280x720 image will look sharp and crisp on your phone but if you project it as 720p image in a movie theater, it would look horrible. This is where pixel density comes in. It is a measure of the resolution that also accounts for the size of the screen. PPI has become the most common way to denote pixel density although pixels per centimeter or PPC can also be used. To calculate PPI, simply measure 1 inch diagonally on the screen and then draw a line diagonally through them, and find out how many pixels it intersects with.
