Overclocking

Post by Akashio » Sun Jun 15, 2003 2:58 pm

How do I overclock my AMD 2100+? Can you overclock other things besides the processor -- if so, how?

Things that have a controllable clock rate most likely are overclockable.


The following are the most common and really the only things you can overclock:

CPU/Memory/Front Side Bus : Main CPU of course can usually be run at a higher Mhz clock rate than what it's rated for. To do this you would need to adjust the settings for your CPU by either adjusting the in BIOS controls or the physical onboard jumpers. Some motherboards do not support CPU frequency control and will only allow autodetection of the cpu. You cannot overclock on these boards unless you can find a hacked BIOS.

Two things affect CPU speed, the multiplier and the front side bus. CPU speed is determined by FSB X multplier. So a Bus speed of 133Mhz X a multplier of 10.5 = 1396Mhz or roughly 1.4Ghz. Most people opt to up the multiplier. When upping the FSB you also are upping the PCI bus clock as well which is a dividen off the FSB(1/3rd or 1/4th usually). Upping the PCI clock can cause some add-in cards or hard drives to not function properly. Also some motherboards force the ram to speed up along with the FSB. So if you have PC100 memory and you up your FSB to 133Mhz. Your system most likely will not work or be very unstable.

Many new CPUs are clock locked. Your Athlon is clock locked. You would there are some 'traces' on the top that need to be connected. This use to be a simple process of using a #2 pencil to bridge the gap. That usually does not work no adays because there is a pit in between the gap. You have to fill it with a small amount of epoxy then use a pencil to fill in the middle.

Most people no longer are overclocking because the returns are not worth the trouble. The high frequency CPUs are already reaching their limit and you'll most likely get only 100Mhz extra out of overclocking. There is also the chance that you will make your system act unstable when overclocking.


Video Cards:

Video cards can be overclocked. Video cards are basically little mini-graphic-computers. They have their own pool of memory and their own GPU. They both have clock rates and they both usually can be overclocked.

Overclocking a video card is only going to really help you out if you play games and even then it may not help you out all that much. You can use tools like PowerStrip/RivaTuner(nVidia)/Rage3D(ATI) to overclock your GPU & memory.

Most people focus on overclocking the memory on the card. Get it as high as it can go before the computer locks up or visual artifacts show up. The returns on this aren't really worth it either. Maybe getting you a couple extra frames a second. Not worth the hassle and the fiddling around.



Overall, now adays it's really not worth the trouble to overclock :P. Maybe if you had a Cel300/366 or a Duron600 :P. Then yeah overclock but the Athlons are not overclocking that great and the trouble to get one to overclock is not worth it. Oh and the investment in cooling the thing off to get it to be worthwhile negates you fiscally, you might as well buy a stock cooler and a faster cpu rather than a elaborate cooler and a bargin bin cpu.

I have to argue the point about oc'ing.
It's actually better now.

As a person who have built many machines, and own many machines I love oc'ing the occasional computer.

Because of the micron process being smaller to create chips, the amount of voltage required on a chip is less. Thus heat production also goes down. What used to be the 1.7 volts required to run a Willemette P4, is now 1.525 to run a northwood.

Unless you are hitting 2.0+ volt's your chip isn't going to be damaged. What this means is you can raise the voltage for stability. With overclocking that's key.

I ran my 2.4 at 3.2 for a while, sold that a while back.

now my 3.06 runs at 3.5.

I think overclocking is worth it. And it's not as dangerous as you think.

Lol..I really didn't aswer the first post.

On what you can over clock.

CPU via Clock Ratio and FSb.

Video Card Via Core Speed, and Memory Speed

Memory Via Cas speeds, and precaching speeds

Mouse - Ps/2 you can up the ps/2 refresh rate for better accuracy

Network - Software overlock, you can turn off features that will speed your connection.

contact me if you really want more in depth.
