Overclocking terms??? ::::

[househead]

Was wondering what's the different ways of overclocking (FSB, Multipliers, jumpers, voltage, etc.)??

What's the advantage/disadvantage of each one....... and how do I know if the MB supports that type of OC'ing?

Also, how exactly do I alter each setting?

Multiplier increment only O/C the CPU. Improve the speed of the CPU.
FSB increment O/C the entire system ie. RAM, HDD, AGP port, PCI slot & so forth. Generally, FSB increment will give u better performance than the multiplier increment. But FSB increment is more error prone (some components didn't like out of spec FSB). Jumpers is for setting in some mobo (some might be jumperless). Voltage increment is for stability & achieve higher O/Cing.

Check out the bios. C if u can change the multiplier & FSB.



<< how exactly do I alter each setting? >>


Just manually change the settings. Of course, in O/Cing...there r many factors to consider as well. Check this forum...u'll know.

Thanks wind!

So FSB, Multipliers is changed in the bios?

jumpers are from jumpers on the mobo?

and voltage is changed in the bios?


So if you want more out of the processor w/out changing the whole FSB, then multipliers are the way to go?

wouldn't changing the voltage give you the chance of shorting out a device?

1. So FSB, Multipliers is changed in the bios?

2. jumpers are from jumpers on the mobo?

3. and voltage is changed in the bios?

5. wouldn't changing the voltage give you the chance of shorting out a device?

If you have fairly new overclocking motherboard, your question number 1 and 3 are applicable and recommended to use it. Try avoid using the jumpers if your mobo allows u to use BIOS to overclock.

4. Yes

5. Not really. Actually if the voltage is lacking, it could endup damaging your hardware including your CPU. If you want to overclock and the system needs more power to accomplish the overclocking speed, you MUST increase the voltage otherwise you're not going anywhere unless your system would overclock at some degree with default voltages. Each CPU's behave differently from OC'ing. Some can do well with default voltages and some don't.. Have happy OC'ing!

Is the voltage changed in the bios?

is there certain mobo companies that usually cater to the OC'ers? I believe soyo & msi? or certain bios' cater to OC'ers?

Are multipliers changed in bios or on the chip?

OT question: Is L1 cache on die? and L2 cache is on the mobo?

thanks!

<< Is the voltage changed in the bios? >>

Yes



<< is there certain mobo companies that usually cater to the OC'ers? I believe soyo & msi? or certain bios' cater to OC'ers? >>

Soyo, MSI, Abit, ASUS, Supermicro, Iwill, Gigabyte, and many more are all good overclocking boards. MSI is one of the preferred picks. Abit and Iwill is my favorite. Iwill seem to have good OC'ing options and very high performance.




<< Are multipliers changed in bios or on the chip? >>

In the BIOS (AMD chips do have unlocked multipliers but not the Intel chips except only the certain version of the old P1 and P2's)




<< OT question: Is L1 cache on die? and L2 cache is on the mobo? >>

For a AMD processors, L1 and L2 bridges are on die chip. Same thing applies to Intel P3 FCPGA chips.

you're welcome

On P4 and celeron chips, where are the L1/L2 located? also, what are the sizes of the athlon/pIII/p4/celeron L1/L2 sizes?

Abit, Iwill, MSI = what bios do they use?

whew! Thanks for the help there! i'm buildin' my new pc, and want to push some extras outta it ;-)

I'm not too sure about the P4 and the Celeron ones on the location of L1/L2 but the size of the L2(which is what we look at most) on the T-bird is 256k. Duron uses 192k. P3 Coppermine has 256k. P3 Tualatin has availability of 256 and 512k. Celeron I & II has 128k. Celeron III (Cel-mine) has 256k.



<< Abit, Iwill, MSI = what bios do they use? >>

Abit uses SoftMenuIII (very good program) Iwill uses SoftMenu but not exactly the same as the Abit ones. I don't know about the MSI. I need to look into that..

That's interesting.....

right now, my wait is on.........

MSI, Gigabyte for their dual athlon boards.................

honestly, i'm a bit of an aesthetic freak, so I might tend towards gigabyte......

hopefully they hab good OC abilities......

How many voltage settings are there? What are the default settings? And how much OC'ing on voltage is safe?

;-)

 

[househead]

Also, by changing the jumpers, what exactly is that doing?

 

[FooDog]

The different voltage settings depend on what bios you have. Newer mobo's will oftentimes let you change the core voltage by 0.05V increments, older ones have higher steppings, around 0.1V.

The safe voltage level depend on number of variables:
First of all, different CPU's have a different default voltage level. Legacy applies here: the newer the CPU, the lower the default. It is really the deviation between the default voltage level and what you set it at that affect stability and heat output.
Bear in mind that a higher than default voltage level will run your CPU hot, and sufficient cooling is key to successful OC'ing. Stock fans are simply out of the question, unless you like the idea of your tower turning into a smoke stack...
An increased voltage level also causes electromigration which in essence shortens the life span of the CPU. But unless you're planning to hang on to and use it for more than five years or so it shouldn't be a concern.

Thanks!

the jumpers?

So voltage overclocking should be kept down?

 

[FooDog]

OK, most modern, and even low budget mobo's, are jumperless so you shouldn't have to worry to much about it. If you really have to know, jumpers were for the longest time the only way you could adjust the settings and corresponding performance on any hardware. This is still valid as far as modern harddrives go where it takes a jumper switch to change it from the default master setting to slave. Perhaps that will give you an idea of what jumper do. They are essentially your very physical control tool for any hardware equipped with it.
