an obious warning to 9262 sli overclockers?

this just ran through my mind and i want to see what you guys think. i have had my fair share of overclocking back in the days (2001) and not much has changed it seems. the scene just keeps getting more power hungry as the clocks increase with every new platform.

anyway, one of the biggest things that i believe goes un-noticed is making sure you have enough power to feed the overclocked system.

on a fully loaded system with sli, the 220w power brick is already operating at maximum effiency and any other additional power requirements might mean instability.

for example, just add the numbers real quick.

2x 8800 cards = 70w
q6700 or q6600 = 95w
3x hard drives = 15w
optical drive = 5w

these alone we are already at 185w. add in the lcd, another maybe 25w i think and we are at 210w. now add in all the other peripherals like tv tuner, usb plug-ins and wireless adapter and we are probably reaching the limit while still maintaning the required small overhead for power-ups and power fluctuations in the current.

i think an overclocked system that is not stable at all seasons of the year is kind of a moot point. don't get me wrong, i think overclocking is a great thing and i am betting laptops are heading into that direction to attract buyers (i just think they need beefier power supplies) but if the overclocked laptop runs into stability issues because the heat of summer comes along is it worth jeaporsizing your file system for that 5% gain and having the constant worries? even if you don't use you system for work, i bet no one likes to spend time with OS re-installs due to file corruption of instability.

 

You can always get a bigger adapter,say 250W or somewhat bigger.
But that turns into the desktop area consumption pretty fast.
You forgot the screen dude,that uses quite some power at max intensity also
All in all,some good points of view.

 

Within reason that would probably work, but wouldn't you rather quickly exceed the capacity of the onboard power management system?

 

I hear OCers do it all the time. Just ask Dexgo, he got a 150W for his M1710, and that unit doesnt` need more than 120-130W either.
It`s a matter of caution. And even so, I would find it hard to believe that Clevo designed the mainboards to work at a nominal power of 220W or whichever the 926x uses, and a 5% increase in power requirementes would kill the system. It`s not healthy on the long run,but it keeps the system stable.
It`s like with cars,if it goes uphill and you push the pedal harder it ain`t gonna go faster by much,but it`s definitely going to eat more gas.
It`s a matter of both perspective and choise,OCing is extreme performance addicts.
And I respect that.

 

I allready checked my system and I'm good.

I didn't increase the voltage on my processor.

I've allready said this.

My Notebook is Stable as a Table.

yes we will see *if I get SLI. but I don't think it's worth it.

Maybe on Dell but Clevo isn't

Plus I know someone that has put a qx6850 in thier RIG with 7950 SLI and they are fine.

they have had it for months and months like this.

the qx6850 is 130w.

plus the 7950's are way more TDP together than 2 8800m's

 

2 7950gtx=90 W under max load.
