No overclock option in your BIOS? No Problem.

Overclocking your CPU can be risky business, however if done properly and with the proper amount of care, it can improve system performance anywhere from 5% to 50% depending on the CPU and how it is overclocked. In this article, I am going to discuss the various methods, benefits and downfalls of overclocking. Remember, ALL forms of overclocking beyond the manufacturers specifications voids the warranty and has the potential of “bricking” your CPU, Motherboard, or both. Therefore I take no responsibility what happens to your CPU/Motherboard if you attempt an overclock. If you are not technically inclined, or feel uncomfortable changing these settings, please give it to someone who is or just don’t try it.

Overclocking creates  extra heat, so it is a good idea to buy a good heat sink to dissipate the extra heat.

The safest and perhaps the easiest way to overclock your CPU is if you have that option in your BIOS’s setup. There are often times the BIOS will contain options to change the FSB (Front Side Bus) frequency or CPU clock multiplier. However, as this article is about overclocking without this feature, I will skip this step.

If your motherboard’s BIOS does not have an overclocking feature, do not worry, there are other options. The first option you have is to overclock using overclocking software. overclocking via software basically changes your FSB frequency or the clock multiplier in your CPU. In order for this method to work, you must have one of two things:

Windows-on-ARM: Hot Topic at CES 2012

WoA: Windows8 on ARM

Windows on ARM (WoA), a combination of Windows 8 and ARM-based processors, is expected to make an official appearance at the end of 2012 and will try to compete in the notebook market as soon as June 2013, according to sources from notebook vendors.

Since players such as Nvidia and Qualcomm have been enhancing their ARM-based processors’ power consumption and performance, if their processors can successfully pair up with Windows 8 and receive Windows software support, the WoA platform may soon be able to compete against Intel and AMD.

The sources pointed out that players with ARM-based processors are aggressive about WoA platform and are hoping that the platform will be able to raise their share in the tablet PC market as well as help them enter the notebook industry that has been dominated by Wintel.

The ARM CPU players are already aggressively cooperating with notebook players such as Asustek Computer and Lenovo and are set to launch WoA-based notebooks to test the water in mid-2013 with expectations to see the platform take off in 2014 and further grab share from Wintel in 2015 to become the second platform of the notebook market

The sources believe that WoA platform’s advantages over low power consumption and price will provide strong competitiveness, but its biggest problems will be software support and cooperation with notebook vendors. If both problems can be resolved, the platform is expected to received strong attention from notebook players, especially second-tier and white-box players.

Intel Ivy Bridge at IDF 2011

Varghese George, senior principal engineer, has detailed information on the upcoming Ivy Bridge microarchitecture that’s due to be released in 1H 2012.

Ivy Bridge is the successor to incumbent Sandy Bridge – the design which powers the majority of Intel’s silicon available today – and it’s considered a tick in Intel’s nomenclature.

Ivy’s central core design is similar to Sandy Bridge in some ways, George said, as it features the same two-chip solution – PCH and CPU – socket, shared cache, and memory-controller found on the incumbent chip.

But George went on to explain that shifting down to 22nm and using the new-fangled tri-gate transistors enables Intel to offer either greater power efficiency or more performance than Sandy Bridge for a set die size, though he would not divulge actual numbers at the technical seminar at IDF.

While performance is clearly important for an architecture that’ll scale from ultra-low-voltage laptops through to servers, George was keen to point out that many of the improvements in Ivy Bridge relate to power efficiency. For example, new power-management features enable more-granular control over the chips’ cores and voltages, extending through to particular chips having multiple TDP settings that can be dynamically adjusted by a PC-manufacturing partner – a range of power settings on one chip, if you will. This intriguing notion was glossed over somewhat, and we plan to learn more tomorrow.
