we always hear that, over clock can spoilt the processor due to over heat

but is it down clock also can burn the cpu ?

My fren have one AMD Barton 3000+ . Original FSB is 200 Mhz. Is it possible i run it at 133MHz FSB? will it create more heat and spoilt the processor ?

fren, down clock will not burnt the processor. it will also sometimes makes the processor temp lower coz of less clockcycles.
but if u are to downclock the fsb to 133mhz, then u might also consider to downclock the ram speed to 266mhz (PC2100) to let them sync so is it more stable.

u obviously dont even know what downclocking is...
either that or lack a little logic

Why would you wanna do that? you paid extra for that speed. But lowering the FSB will reduce heat and preserve the processor for even longer period of lifespan. Theoretically at least. Believe me, it's not worth it since the effect of downclocking will not significantly help prolonging lifespan of a processor.

i think he juz edited the 1st post. juz now he said his fren dowan his children use the pc to play games so want to downclock it.

hahahah
very funny
then go buy PC 400MHZ
can play pacman onli hehehe

LOL, not a brilliant action in my opinion. Games significantly dependable on graphic card, just get a rubbish card and plugged it in.

better down clock the GC then cannot play smoothly...haha

Haiyor, limit the access to the applications/GAMES! Thru windows. Mah easier than downclocking.

And downclocking the hardware to limit the playing of games is not going to help. He has to educate the children, not slow down the hardware.

well one of the main reason people downclock is to cool down the processor that they think is too hot ( 50-60 degrees is still okay friends)

antoher one is they need super silent machines so that they dont need super powerful fans and dont mind the reduce speed. websurfing, office and such would not see a performance increase even if you have a 2ghz processor downclocked to 1.5ghz processor. unless u play games...but the temprature difference is quite high and they dont want/need to invest in high end cooling.

yup..agreed....not a nice idea to downclock the processor. maybe he should downclock the graphic card..hehe
or maybe juz let them use winxp guest account and limit their usage.

down clocking doesnt help much man, unless u download clock a lot!!
then u better go and get the old type of cpu rather a new 1
lolz

i think u shud throw away RAM
juz add 128 onli and install WIN VISTA

....dumb idea u won;t even get to open a doc

y not jus install linux i doubt many gams can run on linux + its free

hahahahha this.. kind for ppl who cannot Overclock.. poweg2 the,,, try make showOFF with DownClock .. huhuhuhuh funny...

poweg2 HUH??

[quotey not jus install linux i doubt many gams can run on linux + its free[/quote]

later his son playing GBA emulator on linux hehehhe
coz WINE now become more powerful
install TEXT TYPE linux?
heheheh

juz put a s3 savage pci graphic card lar...

i never expect there will have a such good respone from all the forumer. Overclockers always think how to run their system in the maximun speed. So, when i post up this topic, i feel funny also coz our discussion area is how to down clock a system, rather want to over clock it.

i will pass every one opinion to my fren.
Thanks for you all precious time to contribute your own idea.

Downclock for the sake of the child seems funny too.

erm....

downclocking a barton 3000+

why dont he give me the barton and i will give him my P3 Rig

get another cheap pc for the children to use, if he is afraid that the children will use it to play game

GOOD LUCK

actually ur friend can create antoher profile in winxp that does not have this applications( Games)

its easy, if u dont want the headache and prefer another way,
install it some folder and remove the icons( hide installation folders )
or use GPE to limit access to certain area's of ur disk

Just create another profile for your child to use. Make the profile cant install any application. Remember to run your antivirus and firewall on the background. You never
know what your kids will do

yes
and make sure u set password to the administrator account that you currently use.
if can, hide the folders that your account uses in windows
or then again use group policy editor to do necessary security policy's u want to enforce

Last time downclock my P4 2.4B to 100Mhz = 1.8Ghz
Power consumption it took was 30W, down 20W++ from stock

Now at 3.24Ghz, power consumed till 90W

from what i understand.. downclocking also will cause CPU, VGA or whatever u downclock to heat up...

how come? hmmmm..... try to think of it as the voltage, supplied, not being used up... if u downclock. downclocking it doesn't use up all the power.

probably u missed undervolting.

I don't really understand what u r trying to say and why downclocking heats up component? What do u mean by voltage, supllied and not being used up? and how downclocking doesn't use up all the power?

i'm sorry ... i dotn' really know..

my tech friend told me that.. .he just said, underclocking can also damage CPU. i left it at that, and didnt' bother to explore further.

as to what soulfly meant by 'i missed undervolting' i have no clue what you are trying to imply.

Actually the effect of downclock and undervolt is much less serious compared to overclock and overvolt. Well, I'm not sure how exactly undervolt can kill CPU, but undervolt inappropriately WILL make the CPU unstable.

However, I don't think underclocking CPU without decreasing Vcore can destroy the CPU in anyway. The theory is simple. A merc can run at 180kph and 60kph well, and running at 60kph actually can preserve the engine more than running at 180kph.

Another fact to backup my point is that, both AMD and Intel use undervolt and downclock to reduce the idle core. They are striving even harder to develop better mechanism to implement undervolt + downclock more aggressively in future. If this is going to kill the CPU or shorten the lifespan, why AMD and Intel is heading towards this direction?

I downclock actually as I dont play games. I use AMD's Cool'n'quite running at 994MHz when I dont need the power.

http://en.wikipedia.org/wiki/Cool'n'Quiet

Yeah, me too. C n Q here. 1.16G @ 0.85v n 2.9G @ 1.41v / 3G @ 1.47v.

ooo. ur electricity bills must be cheaper. my pc power consumption around 300 watts, 2 pcs never off, rm90/month... only 4 ppl staying, 2 rooms. headache..

Sorry if this is OT.

is it normal that CnQ max VID at 1.45v?

No it won't..it will actually run cooler..think about this-when you overclock it gets hotter, its the opposite when you downclock (assuming you don't mess with voltage at all). On top of that, you can undervolt when you're running the processor slower, though there's a limit to how far you can go depending on processor technology (too low-processor will be unstable, overclockers know this too well) and what you can set in your mobo. Underclocking & undervolting is nowhere as dangerous as overclocking, I'll say there is little that can go wrong if you just stick to adjusting settings from BIOS (DON'T be ambitious and pull off your HSF thinking you don't need it anymore since your proc is cooler-those pre-pentium days are looooong over). I haven't tried this on VGA, but it should apply since the logic is the same.

If I'm not mistaken most silent PC sites speak of this technique to run PCs cooler so that you can use quieter, but less efficient cooling (preferably fanless). Just google for silent PC. I've underclocked and undervolted for the reasons above (and a few more obscure ones), if I've time I'll explain further with pics if possible.

PS-someone PM me how to insert pics in posts..im a noob..still stuck with text

i downclock for BT
save electirc bill ma

downclock?
if i downclock my prescott 3.2 to 2.0, can't is become cooler?
coz my cpu temp is damn hot now even using a tt cooling fan....

I just can't understand why you guys opt to downclock your pc? Just like having a Ferrari but just park it in your garage

for surfing and some office work dont need 3.46ghz brute force processor power. so u end up wasting ur energy/electrical bill. i only run my proc @1ghz and still can play some game. best way to downclock is using 3rd party software like rightmark and when u need some power u can load ur preset profile.

With AMD's Cool n Quiet, you don't need to downclock the cpu anymore

I doubt that as even from a physical point of view (atomic physics), when the semiconductor is set at a lower voltage threshold, the accelerating speeds of the electrons within it are lowered because less effect of the magnetic field is on them. If the acceleration slows down, the heat generated will be less.

But there is a possibility that underclocking might affect the CPU but not to the extent that it will get spoilt.

1 question for u.. how far pentium/core2 downclock when eist enable. i hear intel power saving not good as amd c&q izit true. long time didnt use intel since pentium4 era. tq

i never use Intel... so I don't really know

if not mistaken around 3-4 multi downwards from stock speed

Conroe's lowest multi is 6 so you do the maths lor. Tak jimat banyak really.

so that mean finally we can lower the multi for intel for oc purpose izzit?

should we have downclock club challenge in lyn....

Check this article from silentpcreview, its about undervolting the processor to save power

http://www.silentpcreview.com/article313-page1.html

the numbers are quite surprising, even the Athlon 64 X2 is pretty amazing (Conroe wasn't out yet for another few months when the article waas written). Never expected AMD's CPUs to take up so little power when tweaked right. Of course, this article makes no sense to overclocking addicts..

Maybe can hold competition for lowest power consuming PC (and probably most silent & coolest running) that can meet a certain level, say, 3000 3Dmarks in 3DMark2003? Should be interesting..

i agree with u
but better if we using superpi only, coz graphic card will effect a lot in 3dmark03. but i donno what happen if using my amd64 @400mhz and pairing with 7950gx2... either one must be choking...

Merom can jimat banyak, because default multi can go as high as 15x. With low bus speed, 6x can actually brings the CPU below 1000MHz. Well, Core2 Duo initial design is for laptop usage, high FSB is not the target. So i guess 6x is pretty sufficient for initial usage.

I said "Lowest POWER consuming". Taking the graphics card into account by including a graphics benchmark would make things even more interesting. Whats the point of saving 20W on the processor only to have it spent by the graphics card? Can set a few categories based on minimum required benchmark performance (can set a variety) and find the best tweaked system for lowest power consumption. Think its about time competitions like this came up, considering how insanely high system power requirements have gotten these days and the current performance-per-watt craze.

Only catch is that they'll need equipment to measure the power consumption, preferably from the wall socket so can also take PSU efficiency into account. For active pfc PSUs with power factors of >0.99 measuring from wall socket is easy (shunt resistors), but for those non-active pfc with lower power factors need slightly fancier equipment which I'm not sure where to get.

sorry my mistake! i got ur point already.. but u just mention how hard to measure total system consumption. even if we using a active pfc psu we still only 85~95% power effeciency and not everyone can afford to buy clamp meter to measure from wall socket plus they can give a wrong information. btw we still need a more supportive member to give more opinion.

Well I just had a few ideas on how to measure system power, however all have their weaknesses. Clamp meters are not cheap, a cheap alternative is to use a shunt resistor in series in the power cable and measure the voltage across it (using a DMM) to calculate the current and power drawn. Problem is when the PSU has a power factor below 0.99, the current measured by this method or with a clamp meter will be higher than the actual amount. Its also possible to use a UPS and measured by the time it lasts before the UPS runs out of battery power-but I heard this is also affected by power factor although I'm not sure.

Btw, power factor and power efficiency are 2 different things. Very few PSUs can boast efficiency better than 85%, even 80% is achieved by only half of the quality brand PSUs while any active PFC PSU can easily achieve PF >0.95. For more details, read the article link below.

lol i downclock sometimes when not using full capacity

btw, the person must educate the children not 2 play
not downclock

running away from the problem
