Is underclocking a dangerous thing?

basically his point is running excess(stock) voltage for lower speed(out of spec) is a dangerous.

and my point is the chipset itself is running on stock voltage and its fine even if the bus speed 400mhz is running lower then the state natively supported 533-1333mhz

thank you close_deal.thats exactly my point.i also pointed out that if a chipset is rated to run at 1333 natively then it doesnt mean anything lower is impossible or dangerous as he said.

im sure you cant undervolt any parts apart from CPU and the rest on "Normal" or "default"

well he would post in here sooni think.beginning with "E".im off to work now

Poor guy, working on a saturday.
Who's E?

How did he come up with that anyway? People are weird.

Ah are you referring to Evilonigiri and his underclocked Q6600?

I don't see why it should. I guess there is only one way to find out, though

lol nice guess.

thank you again!

i really want that friend to see what all you guys said.that guy is funny he can side track himself and talk as in manufacture's view and said should not run parts out of spec even lower then and so that would be dangerous.

i feel like slapping him,because i told him we are consumers why are you talking in manfacture's view?as we are not going to benefit from it or something.and he just like just put me as a manufacture!

I MEAN WHAT'S THE POINT OF THAT?think like a manufacture?

Shadow703793

and he is the actual person denying what he is doing.underclocking his Q6600.

all CPU and ram is the same in the same model.but the manufacture just select a lower multiplier for them so they run slower and sell for cheaper as well.

so a q6600 is a downclocked qx6800 but with locked lower multiplier.but the CPU it self is CAPABLE OF RUNNING AT 2.93GHZ because its the same chip as the more expensive brother.and once again he point it that as dangerous as its running outside manfactures stated spec.i guess he never think its actually running in spec for the core inside the wrapping.

yeah.normal the lower speed parts have lower level in quality as well.manufacturing variation and defect.couldnt run as high as the others.but the chip when its made.its design to run at the same voltage.but the actual silicon inside disallow it to run at a higher speed even with the same "normal" voltage.that why when we OC a cpu we put more voltage to offset or overcome the defects or inferiority of the CPU.

is INFERIORITY a word?i think i just made it up.lool

so reply to his question.underclocking to 100(QDR400) where a board support only 133(QDR533) Pentiums.so that can be look as out of spec.as the NB is using the stock voltage rated for 533mhz and over.

you think its dangerous?

yes to both.

just to let you guys know how this arguement started is wheni just talking some funny stuff to him,i sed if i run the e2160 at 100x6 i wonder what the setting and tmep would be.and he just started talking about its being dangerous!lol

yeah i know.its possible that why i noted that to him and i said i will try it out.but he go and try to scare me away!lol

I thing it goes like this:

Underclocking - is fine for power saving, less heat and prolonging lifespan, but it may cause instability if you go too low. Not dangerous. Comp goes sloow.

Stock - well we all know that works right . Boooring who does that...

Overclocking - dangerous because your making it work out of it's boundaries both voltage and Mhz wise... Increasing heat, power consumption and shortening lifespan. More raw Power and bigger e-penis.

Excellent point, but my argument is, is underclocking safe when overvolted? I don't think that will prolong lifespan.

I created a new thread here: http://www.tomshardware.com/forum/ [...] unsafe#bas

I guess I'm an one man army. What OCing enthusiast will UC?

That's true, and I know that, but I don't think 800MHz at 1.5V will do any good[/extreme example].

Does anyone know where the clock generator is for the NB? As in is it actually built into it. It is valid for the discussion.

It'll be obsolete long before it burns out anyway.

It would because electrical devices only draw the Current they need. I can see your point here, because too much voltage can kill. What your suggesting though, the stock voltage wouldn't be enough to actually damage the chip.

Ok i think i've got this right in my head now... A CPU set at 500Mhz can be forceably overclock by manually setting the frequency you want it to run at an give it a little more voltage. For the clockgen on the NB to keep up you have to increase the voltage slightly. Thats why you get FSB wall on the mobo first normally, becuase the CPU has a little more headroom than the NB can handle.

Therefore decreasing the actual frequency of the of the CPU will lower whats travelling through to the NB, but the NB itself is still within it's parameters because the FSB is now lower than it's standard running frequencies on stock voltage. However if the frequency gets to low for the NB clock gen (normally not the CPU) to handle you get the instability.

Ok i think thats right maybe a few more edit's to get this completely right ...

I would hazard a guess and say so. The NB chip is still running at it's req'd default voltage but drawing less current.

*EDIT* Also as 4745454b says the transistors (nand gate switches) even on micro processor level need a req'd voltage to open and close.

My electrical engineering only goes as far as aircraft avionics, so i can't give solid facts just slightly educated ones . Just the way the CPU and NB talk seems to be similar to the way the Main comp sends data packets to the rest of the systems...

Nah it's not that impressive. My qualification doesn't even allow me to do basic housing rewiring tiz daft , but hey I can work on aircraft so i can't be 'that' dangerous hehe.

Lol - EE is a easy really. Took 14 months for me to be fully trained from a 16year old squirt to a 17 yo slightly taller squirt . Plus after 6 years on the job it tends to get blown out and replaced by the cobwebs hehe.

P.S If you ever do wave guide theory and actually retain the information give me a call b'coz that almost turned my world unside down

Evilonigiri, the mobo won't be damaged by lowering the frequency. As was said, you aren't over-volting the CPU, RAM or mobo, just lowering the speed.

Let it go.
