what is overclocking does and difference between???

hi again,i heard from my geek friends about overclocking the CPU,they just don explain to me in a simple way....i wanna know what it does???
what is the difference between core2duo and centrino2??which is better?
thanks many.....

 

Overclocking in simplest terms: you are pushing a component (usually CPU, GPU, or RAM) faster than what the manufacturer intended by manipulating bus frequencies, etc.

 

Overclocking....Already the word itself implies that you do something to your system that will yield a result over...the standard clock.

You need to reasearch on the following:

MOTHERBOARD!!!!

1. CPU Clock
2. Multiplier
3. FSB
4. CPU Voltage
5. Chipset


Your system has speed x. By manipulating the above mentioned things, you will make your system have the following speed x + the margin allowed by the components.

This margin is influenced by the following:

1. CPU engineering samples tend to overclock higher than normal ones.
2. Cooling. Good cooling means lower temps at higher clocks.
3. RAM Very important. Depending on the RAM you buy o/c can give different results.
4. A good mobo will allow you to tweak the system by increasing voltages on CPU, RAM, etc.

 

Overclocking is increasing the clock speed of a computer component past the manufacturer's specifications. Typical components that are overclocked are the CPU and the graphics card. Manufacturers set conservative clock values because they want the components to stable and reliable in varying thermal environments (i.e. hot and dusty rooms). When a component is overclocked, the heat output is usually increased as well. Not to mention, an effect called electromigration occurs when a component is overheating. Electromigration causes electrical components to fail prematurely. Overheating computers results in instability and crashes.

People who overclock computer components are traditionally called overclockers. Overclockers typically overclock to increase performance for games and other programs. Also, some overclockers do it just for fun. Typically, overclockers need advanced cooling (i.e. aftermarket heatsinks) to keep their computer cool and stable. Otherwise, their computers will crash, experience instability, data errors, and other undesirable side effects. Generally, overclocking is easier to do on a desktop computer versus a notebook computer. The reason is better aftermarket cooling solutions are more readily available for desktops than notebooks.

Overclocking is a risky endeavor for the novice computer user. Only enthusiasts who know what they are doing should try overclocking. Overclockers have a saying: If you cannot afford to lose it, do not overclock it. If something bad happens, you only have yourself to blame. Overclocking should only be done on non-production environments. If you need this computer for work, critical applications, etc., you should not overclock as stability is more important than the increased performance.

Core 2 Duo is just a brand of CPU developed by Intel. Centrino 2 is a computing platform developed by Intel. Centrino 2 is just a notebook computer that has a Intel Core 2 Duo CPU and an Intel wireless network card. The Centrino 2 platform is known for its energy efficient, yet powerful components.

 

thanks all....now i got better understanding of overclocking....that means centrino2 is better for gaming and work?
how u know how much ram your laptop can hold up to?

 

Centrino 2 and Core 2 Duo aren't in the same category; as Centrino2 USES Core 2 Duos.

All the latest processors from Intel are all C2D (except for the quads and extremes), while Centrino 2 is a platform.

You should consult your friends more about this, and post more on NBR to get a better understanding.

The most on 90% of notebooks is 4GB RAM and can be 6, 8, 12 or even 16 on very expensive machines.

 

thanks thanks....another questions(sorry)....
INTEGRATED VS. DEDICATED GRAPHICS CARDS??
HYPERMEMORY AND TURBOCACHE?

 

explain in simple words:

overclock CPU = not so good
overclock GPU = good, but heat is no good, so need cool down

core2due = CPU
centrino2 = core2duo + intel chipsed + intel wireless card

integrated graphics = no good for games, but good for internet and MS Office
dedicated graphics = good for games and autocad, but less battery life

hypermemory = more memory from RAM to video card, for ATI cards
turbocache = more memory from RAM to video card, for nVidia cards

 

Can you please explain why it's good to overclock the GPU and not the CPU according to you?
Both should be fine with good cooling, neither is "good" or "bad", it's only bad if you're a user who doesn't know the risks and overclocks the CPU or the GPU in a manner that the component overheats or is nearly overheating. Aslong as you can keep it stable and cool, it's "good".

So why are you saying overclock CPU = not so good!?
I don't get it.

 

Look ... i dont mean to flame you (@just geek)

If you dont know what it means and you have to ask in the forum, chances are you are not supposed to know it (especially overclocking). Heck ... what good is it gonna do for you anyway ? (ie. if you are computer illiterate, well so be it, nobody cares anyway)

If its your curiosity ... well, google has more answers than you need in your entire life

 

because it's not needed most of the time. A 2GHz core 2 duo should be enough for the average user for anything, even gaming. I'm yet to hit 100% CPU utilization on my laptop.

Plus, most nowaday CPUs have locked multiplier thus in order to overclock it you have to increase the bus speed, which can cause problems with other components in the computer. Although up to 250MHz bus speed is achievable, it doesn't yield much performance boost.

overclock the GPU - big difference. Put decent SSD - also big difference. Overclock the CPU - meh .. same thing

you see my point

 

I'll explain part 2 since everyone explained part 1. Core 2 Duo is a processor from Intel's Core 2 line with 2 CPUs while Centrino 2 is the successor to The Centrino brand. Centrino is Intel's marketing thing for a Core 2 Duo processor, Intel chipset, and an Intel wireless card. Centrino 2 dictates for everything in Centrino and a 1 GHz FSB for the processor and an Intel Wifi Link 5 series wireless card. The wireless card allows for wireless N and I think Bluetooth.

 

brilliant....thanks....got better understanding now....
the processors got T7500, P8600,i know there is a few more letters,which is better,how u know which is the fastest one,the numbers?

 

Yes i do see your point But i mean as far as you're OC'ing safe there is no "bad" involved, if you see my point also. But i guess you meant to say it doesn't perform anything noticeable to OC the CPU compared to a GPU or putting in a SSD

 

Just Geek. Please post your spec here so we can get an exact idea of what you want or what you can get.

 

You seem to have this idea that overclocking is standard. It is not. Two identical systems might yield different results. There is no red button you push and you get the desired result. CPUs come in batches. Some have greater tolerance to o/c some have less. So, if you buy tomorrow an 8300 you might take it higher than I can take my 8300 because yours loves heat and voltage more.

Bottom line, the P8600 might not be as overclockable as the T7500. Or vice versa. There is no standard. I recall when the E6600 came out. I bought one with my cousin. We had identical specs and mine went to 3.75 on air. His stopped at 3.6. He needed better cooling and better rams. To take it higher. I did not. Mine was the better one in the batch.


The same applies to car engines. You think all of them come with the same power? For example. Two Ford 2.0 TDCI engines might yield different bhp. One 136bhp the other less. So, Ford will remap the ECU for the lower one and bring it up. They will not throw it away .


This is known as the "batch" principle.

 

that is untrue. different setups yield different results

for my cards, they're already pretty much spitting flames out the back of my vens bone stock. OC those things and the big increase in temps are not valued because of the little increase of performance.

which leaves me to set the memory timings and or OC my CPU.

overclocking the CPU on my machine yields very nice results (with a 250 mhz OC). benchmarking wise, it can increase it about 600-800 points. gaming wise, it will add a few FPS but mostly keep the frame rate running much more stable.

it's all a matter of trial and error. some machines work better with it.

 

^ good for ya For me it's pointless to overclock the CPU.

not quite true. All ECUs will come with one and the same map. The engines however may not all make 136bhp. One may make 138, while the other may make 134 ... but usually they will be pretty close.

even Bugatti Veyron engines come within 20hp all, and with those it's much more difficult to maintain same HP due to the power (~1,000hp), and due to the fact that they use turbos.

but that's different talk

 

Intel Core 2 Duo processor T7500 2.2ghz 800mhz FSB, 4MB L2 cache
Nvidia Geforce 9300M GS 256MB up to 1GB Turbocache
4GB DDR2 RAM(upgraded from 2GB)
250GB HDD(5400rpm)
