Dabs Magnificent Seven

Component Advice: Motherboard checklist

With the help of our friends at Asus, we have put together the first in a series of a component checklist.  This will be aimed at giving a bit of advice on what features to check for when you’re on the look out for upgrade components to your PC.

First up, we’re looking at Motherboards and we have condensed the major requirements down to a magnificent seven (unrelated to the name of the Beckham baby girl).

Socket Type

The crucial point with socket types is that it must be compatible with your CPU choice.  The main benefit of buying the latest socket is that it allows for an extended potential for future upgrades, thus a careful investment now should ensure that you go longer before you need to consider reinvesting.  The current set of sockets of choice include Intel 1155, 1366 or AMD AM3 or AM3+.

Peripheral Connectivity

Think carefully about what you want to use your PC for and what peripherals you’ll need to fulfill those requirements.  What do you want to connect it to?  If you have a USB3.0 external hard drive then you’ll want to have USB3.0 on-board.  External HDDs, Monitors, printers and cameras can all have specific connections, a few quick checks beforehand can make things a lot smoother in the long run.

RAM Type

Perhaps the most important considerations for RAM choice is the type and capacity.  The main types of RAM include, SDRAM, DDR and Rambus DRAM.  Synchronous DRAM (SDRAM) is one of the older formats and as such would be slow by today’s standards.  DDR3 would be a good choice for most.  Capacity doubles in size from 8GB to 16GB to 32GB and so on.  Also important to be aware of is the number of dual in-line memory modules or DIMM slots that are available, more slots mean better upgrade flexibility.

Storage Connectivity

Storage connectivity can vary from HDD to SSD to Firewire and more.  Do you need SATA 6GB or SATA 3GB?  It comes down to future upgradability and overall performance you want to achieve.

Graphics Solution

Essentially there are two options; On-board or Dedicated.  With on-board graphics you’ll be equipped for basic computing with outputs along the line of DSUB, DVI, HDMI or DP.  If your rig is going to be built with gaming in mind you’ll need multiple PCI-Ex16 slots for up to three add on graphics cards.

Size

The size of your case will dictate what size motherboard you can use.  The typical range of sizes are Mini ITX, mATX, ATX or E-ATX.

Expansion Slots

The final point on the motherboard magnificent seven is expansion slots. The two main varieties are PCi and the newer PCI-e, which has improvements which include a more detailed error detection and reporting mechanism.

Now that you’re more familiar with our chosen ‘motherboard magnificent seven’, let me know what you think of them all.  Is there any others that you think should be included?  Are there any that you’d like more information on?

Let me know and I’d be happy to produce a more detailed profile.

Solid State Drives: What’s the buzz?

Solid state drives have been a popular inclusion into many PCs recently, and the list of benefits for adding them into your setup is long.  Yet I’ve recently talked to a few people on Twitter and on Facebook to explain why they are a good option, so I thought I’d put together a short guide to walk you through what they can bring to your PC or Laptop.

So, solid state drives. Where to start? I think the main point is to understand the difference between a hard disk drive (HDD) and solid state.  A HDD is a magnetic disc that has data written to it as it spins, from one edge to the other. A solid state hard drive has no moving parts and is very similar to RAM, writing data to a microchip rather than a magnetic disc.

One of the main problems with the more traditional HDD is that it writes data to the magnetic disc in sequential order, meaning that it starts at the edge and writes the data moving inwards or outwards (depending on the manufacturer) in sequence, so that the first file saved is written first, then the second one is placed after that.  When it reads back the data, it has to spin up (making a noise) and find where it stored the files on the disk.  This takes time, and will slow down the data loading process.

 

The other issue with a HDD is with fragmentation.  If you save files in a certain order, and then delete a file, there’s a space left on the disk to fill.  The next time you save a file, it will be saved into that newly emptied space, whether it fits or not.  If it doesn’t fit, then your computer saves part of it into that gap, and the rest of the file to the next available location on the disk.  This fragmentation of files means that to load a program your HDD must find all the pieces of that file seperately and then piece them together, which further slows down the loading time.

There are several other benefits to having a solid state drive which I’ll quickly name check. Lower power consumption, much faster read / write times, noiseless, and mechanical reliability (no moving parts to wear out). However, there are draw backs too.  Solid state drives are more expensive, so generally they are sold with smaller capacities than HDDs. This means that they may not be for everyone.. However, if you’re not a power user or work with smaller volumes of data and are happy with 120GBs worth of space, then a solid state drive is a fantastic way to improve your system boot times, speed up your PC and keep the noise down.  Couple this with an external hard drive to store your music or videos and you have yourself the perfect set up.

So, if you’re interested in seeing what’s on offer, take a look at Intel’s range of Solid State hard drives, or the excellent Kingston V100 range.  If you have any questions about choosing the right SS HD, get in touch via Facebook or our Dabsdotcom Twitter page and I’ll be happy to walk you through it.
