MotherBoard Buying Guide


best motherboard 300x180 MotherBoard Buying GuideMotherboards specifications have gained sheer importance espeically in this age of high definition games and intense memory requiring operations with high data rate busses , high data transfer rates, high graphic cards busses , dual channel and DDR3 rams and the list goes on.
If you visit your local computer market , you may hear some of the below listed specifications while buying motherboard:
  • It supports SATA 3.5Gb/s.
  • It has PCI Express Slot.
  • Builtin VGA of 384 (Plus) Memory.
  • Supports DDR 2 and DDR 3 RAMs.
  • Supports Core 2 Duo processors.
  • 6 channel Built-in SoundCard.
  • 1 Giga Lan Builtin .
  • Built-in WiFi card
These above options may or may be not enough to check motherboard’s technological strength and many other aspects.
We may not be able to standardized motherboard selection process, but common factors that may come under consideration while purchasing a customized PC vary on the basis of needs and usage, for instance, computer gamer may require high GPU and latest video technology than any other aspects of the motherboard.
A common computer user may consider couple of points before purchasing computer motherboards:
  • Motherboard Brands like Intel , Asus, AMD, Nvidia chipsets.
  • CPU technology support and CPU Extended Speed Support.
  • Video technology & Graphic Memory.
  • Memory Controllers.
  • Storage Technology.
  • Peripherals
  • Some Extra Add-ons like Memory card reader, E-Sata etc.
Motherboards brands:
Choosing motherboards while planning for customized pc is always been a difficult task to meet, because of the verastility it offers and technology that may be available by different brands in different names.
Visit different motherboard manufacturer websites and have complete research about the motherboard specifications and technology it is ready to offer and capable of. Most common brands that are being used may be Intel, Asus, VIA, Nvidia, MSI, Mercury and etc.

CPU technology support and CPU Extended Speed Support:
Metaphorically, technology is evolving day by day. Nowdays, choosing right CPU for matching your needs is a difficult decesion, because within same brand it varies alot in technology. Like Intel has to offer lot of variations in the same core series. But what should be considered while considering CPU may be :
  • CPU Speed i.e. 3.2 Ghz
  • CPU FSB (in simple Bus Speed) this may be available in the range of 533 Mhz to 1333 Mhz.
  • CPU Cores like Single Core, Dual Core,Core 2 Duo, Core 2 Quad, iCore and in AMD it may be like AMD Athlons , AM2, AM2+ , etc.
  • Internal GPU (Graphic Processing Unit) capability.
Video Technology& Graphic Memory:
If we only have look on intel, it has alot to offer in built-in video technology ranging from standard video quality to HD quality experience. Bultin Video technology is enough for usual multimedia and office operations. But for extreme video usage like high definition games and video editing softwares, you may need dedicated graphic controllers on the motherboard. Builtin graphic memory ranges from 64 mb to 384+ mb memory shared with your memory controller installed and it may affect the performance.
Memory Controllers:
Memory controllers have been evolved so much from SD-RAMs to DDR RAMS, DDR-2  and now DDR-3. All they have to offer is speed and high data tranfser rates. While purchasing motherboards, one should keep in mind about assessment of maximum memory installation support i.e. like motherboard may support 4GB all in all and kind of architecture like DDR 3 and some other termonolgies like dual channel support.
Storage Technology:
While choosing motherboard , storage technology support is also an important factor to consider, whereas storage technology has also been changed drastically in recent years, ATA, ATA 133, SATA , SATA 3.5GB/s eSATA .
Peripherals:
In most of the recent motherboards, PS2 Mouse and Keyboard ports have been removed and now it comes with as many as USB ports. But this would be an additional bonus if new motherboard is also capable of PS2 mouse and keyboard as sometimes it really helps alot.
  • Builtin High definition sound cards with 6 to 8 channel supports are easily available in newly designed motherboards, but one should consider if it also supports SPDIF output.
  • USB 2.0 ports are available in recent motherboards, but now days USB 3.0 is more trendy in the technology for high speed USB transfers. Check it out if it is available.
  • Firewire port is an additional benefit , if it is available on the motherboard for high data transfers.
  • DVI output for high multimedia interface.
  • PCI Express Slot.
  • Lanfor neworking support.
Extra Add-ons:
  • Memory Card reader is an additional feature if it is available in the casing and supported by motherboard.
  • eSATA port is also an additional feature for connecting eSATA directly to PC as removeable device.
  • HDMI port for extreme visual experience.
  • Wireless Lan for networking support.
Final Thought:
First assess your requirments based on your usage, if you are game lover than always go for dedicated (seperate) graphic card controllers, because shared graphic controllers may cause you issues in playing high graphic requiring games.
Whereas , customizing PC has lot of advantages over already designed PC but for availing these advantage one should know what to add and vice versa.

Computer Power Supply Unit (SMPS)

SMPS - Switch Mode Power Supply - is the technical term for what we generally know as the computer power supply unit. It is basically a box-like device used for the supply of power to your computer unit. So what does it do? In very simple terms, it converts the AC (Alternating Current) power supply from the general electrical sockets available at your home to DC (Direct Current), basically the type of current you get from a battery. The "Switch" term in the SMPS comes from the fact that the computer power supply unit converts AC to DC using switcher technology. We now use the ATX supply power units for the computers as the industry has settled on a standardized case and motherboard (ATX).

Typically, three voltages (12V, 3.3V and 5V) are supplied by the power supply unit.

If you are selecting a computer power supply unit, how do you go about doing that?

1. The first thing of course is to know what power requirements you are looking at. You can check the power requirements of the various devices of your computer and add them up, or you can just ask the vendor for the same. Once you have the total wattage, (that will be the unit of power), you can go for a slightly higher rated SMPS.
Now why you want to do that is because, at a later point of time, if you want to upgrade your computer, like a new DVD RAM drive, you may need a higher power supply.
One more thing to remember is to check the actual wattage against what the label on the power supply unit indicates.

2. It is always a good idea to go for a branded power supply unit. But that might not help if price is an important criteria.
The SMPS supplies power to all the components of the computer, like the motherboard (24/20 pins), hard drives and CD ROMS etc (IDE 4-pin), floppy drives (Floppy 4-pin), etc.
What happens is that, once the computer is powered on, there is a surge of current and as a result, it gets heated up. The fan, in such a condition is crucial, other wise, high temperatures might result. You should have at least one 80mm fan. It is even better if there are two fans instead of one.
(One such problem is the continuous restart of your computer as the temperature rise due to a faulty power supply causes the computer to shut down without giving any error message, and in some cases, not even the BIOS screen.)

If you have a branded SMPS, you can rest assured that there is not much chance of such an event occurring.

3. Number of connectors and the efficiency rating – These two factors are at par with the other factors while considering the computer power supply unit. The efficiency rating, is important as it is directly related to the heat output and subsequent temperature rise. Higher efficiency rating ensures that the SMPS causes a lesser rise in temperature.
The number of connectors is important as it determines how many devices you can use with your computer.

4. Lastly, the noise level – Apart from the CPU fan, the SMPS fan also determines the amount of noise generated – Except from a fine whirring sound, which is basically indistinguishable, you should not have any other sound coming from the SMPS.

How You Can Control Diabetes With Yoga

Balance
The pancreas produces two hormones insulin and glucagon, which help the body balance blood sugars levels.
The healthy function of the pancreas is important to a person's ability to process sugars and starches, a poor functioning pancreas can lead to diabetes.
Diabetes
A person with diabetes has an inability to process blood glucose because the pancreas does not produce enough insulin.
Certain Yoga poses have recently been recognized to help the function of the internal organs and specifically the pancreas.
Regular practice of yoga can benefit those who suffer from diabetes. Yoga helps reduce the stress hormones secreted in the blood which can help reduce the body's production of glucogon and therefore improve the bodies insulin production.
2 yoga poses:
The ushtrasana or camel pose, and the dhanurasana or bow pose, have specifically been found to help the function of the pancreas and benefit people with diabetes. However, theses two poses may be challenging at first.
Easier Poses
The following yoga exercise is also beneficial to the function of the pancreas and is better for a beginner than previously mentioned poses.
Lie on your stomach with your arms up over your head, palms facing each other. Your legs should be straight and comfortably apart. Slowly raise your legs and arms so that your weight is shifted to resting only on your abdomen.
Hold this position for as long as you comfortably can. Ideally, you will be able to hold this pose for forty seconds.
After you have held the position bring your arms and legs down to the resting or beginning position. It is beneficial to repeat this exercise five times.
This and other yoga exercises massages the digestive system and help the function of the pancreas and other internal organs.
To conclude
Yoga practiced regularly can reduce stress the side effects of which can be diabetes.

The Real Benefits Of Using A Silent Inverter Generator

The Benefits You Gain Out Of Your Inverter Generator Includes:

  1. High Quality Power Output: The precision of the Inverter Generator electronic technology ensures its power is closer to normal "line power" in more than any other generator design. Inverter Generators produce power that is as reliable as the power you get from your power outlets at home.
  2. Lighter, smaller size: Advanced engineers use inverter technology to integrate parts from the engine and the generator. The mechanical parts to the alternator are now combined with the engine flywheel. This allows inverter generators to be smaller and lighter in weight than most conventional models.
  3. High Fuel Efficiency: Economy- Throttle allows the generators engine to automatically adjust the engine speed to produce only the power needed for the appliance in use. Traditional generators have to run at 3600 rpm to produce 60 hertz (cycle) electricity. But inverter generators with Economy throttle can run at much slower rpms while maintaining frequency and power for the requested load. Because the engine does not have to run at full speed constantly, Economy throttle reduces fuel consumption by up to 40%. It also helps to reduce exhaust emissions.
  4. Quiet Operation: Silent inverter generators are substantially quieter than traditional generators. The Economy throttle also reduces the noise level, along with the sponge dampening materials that absorb the engine's sound to help make the inverter generators incredibly quiet.
  5. Parallel Capability: Inverter Generators can be paired with another identically sized unit to double your power capacity. Parallel capability allows you to use two smaller, lighter generators to do the work of a much larger generator without effecting portability.
