overclocking 260m

hi guys i just got my cooler and i overclocked the gpu to where it got a 3dmark of 12000 holding at around 70 degrees.

the question i have is: am i somehow screwing up the card by overclocking?

i know that heat is the main issue with overclocking, but if you can hold a steady temperature thats below any minimum danger level then would there be a problem with overclocking? would i be screwing or shortening the life of the card?

thank you

edit: holding at max around 70.

 

Yes, you shorten the life of the card when you overclock...

This will be less though, since your temp is lower, but AFAIK, it still hurts the lifetime of it...

 

When you overclock it raises the card's voltage as well. Meaning more heat and less life time. I only overclock when playing a game so I guess it's up to you on what you want to do.

 

(Emphasis added) That may or may not be true, it depends on whether you're adjusting just the clocks (driver level, no voltage increase) or adjusting the clocks and voltage (BIOS level).

 

I'm just assuming that if you are overclocking you are raise the clock speeds. Which in turn should raise the voltage some.

As long as you don't have the overclock active all the time then you will be just fine.

 

You aren't damaging the card unless you clock it to unstable levels. Safely overclocked cards will last just as long as stock ones.

Don't be scared. Just monitor your temps and test for stability and artifacts.

 

ok, so what was your break down score and the over clock you used?

 

Aslo, what is your CPU and what nvidia driver are you using? Then we get an idea where you should be.

 

yeah, what anothergeek said!

 

When you over clock your card using Rivatuner, as far as I know, the over clock only comes into action when you play games right?

 

- The voltage does not increase as you increase clock speeds. However, to achieve higher clock speeds it may be necessary to increase the voltage (for stability), this in turn has the largest effect on temps.

- That's right, you may as well only OC when you're gaming since otherwise it's just running hotter than it has to be and sucks battery life.

 

With powermizer, that really isn't a problem. I still get 2hrs battery life on 100% brightness web browsing even with the overvolt in place.

 

i use nividia control panel, the order i had was unstable cause when i was testing it the driver failed on several occasions bringing me back to the desktop.


650 1000 1550

i was just wondering about some of the other negative effects of overclocking if heat wasn't a concern, but if you guys want to help me find a stable overclock i wouldn't mind ;]

 

Are you saying 650/1000/1550 is unstable? It's probably the core clock, so turn it down to like 625.

 

yea it brought me back to desktop with driver error after playing crysis on very high for 10 minutes lol.

i will test that 625

btw does the high performance on the battery option help in benchmarking?
i know the low power option dramatically decreases capability.

 

I just leave it on high, unless I'm unplugged.

 

i should go test the score of high and balance on 3dmark

 

I wanna see your 3dmark with your overcloked 260M

 

im new to overclocking.
how do i get started? which drivers do i use? which version and standard or modded/custom?
can i oc the processor in np8662?

 

They listed above some overclocking tools for the gpu, but as far as I know, the cpu isn't overclockable in the M860TU.

 

Your card isn't stable because you broke out of the original core/shader ratio. Try 650/1625/1000. Also, make sure you up the voltage to 1.05v.

 

wow i never you have to stay in the same ratio....

and what does upping the voltage do? nividia control panel doesn't let me control the voltage, would that tuner tool i saw before let me do that?

rivatuner? was it?

 

You can only raise the voltage by flashing. Your card is writing a check it's voltage can't cash. You will need to increase the voltage to 1.05v if you want to have stable operation at those clocks.

 

Yeah Soviet Sunrise is right, try to keep your Core/Shader ratio at 1/2.5 that should help you keep stable.

 

can someone post what core/shader/memory clock ratio's they have had success with WITHOUT flashing the BIOS to overvolt the GPU?

 

Overlclocking laptop gpu is silly. u basically gain about 2fps, you loose life on the card and you creat ridiculously more heat stick to cpus

 

That's only if you keep the card overclocked. Most don't and then it underclock automatically. Unless you play games 24-7 then it won't effect the life of your laptop. Also I've got a 10 fps boost in Cod4 from overclocking, but I don't need it for that game only Crysis.

 

bueller...bueller...

core /shader / mem clocks for the 260m plz!

 

Please procure a notebook with a GPU worth overclocking (none of that 128-bit peasantry), then complete the task. Subsequently, return with a more accurate assessment on the merits of raising the factory standard frequencies of a GPU.

 

^^^lol^^^it's all about getting the most out of the machine with the least amount of money...Plus it's interesting to do.

 

what he got.... a netbook

 

Even the slightest overclock over the card's threshold shortens its lifespan, not much if, say, you overclock the memory by 50 MHz.

Temperature, Amount Of Overclocking, Overclocking Time Span and Voltage determine the damage that the Overclocking did to your cards.

With the proper cooling, you can minimize the amount of damage caused by Overclocking.

If only the Intel Atom Processor could be overclocked to 3.0 GHz...

 

The one thing I want people to understand, is that overclock does not automatically equal damage. If I overclock a GTX 260M to 600/1500/900 today, and can run ATi tool for hours with no anomalies and, I expect to be able to do the same 3 years from now.

 

lol
yeah, i was being funny..lol

 

Agreed, when I did 650 / 1650 / 1050, ATI Tool went, "Hey, hey, are you trying to kill your cards or something?", about 50-70 delta artifacts popped per 3-5 seconds, you can see about how bad it is, with 650 / 1650 / 1025, there was no problem.

The ASUS EXEE PC, the only netbook that can be overclocked to 3.0 GHz... Hah.

 

oh snap!..are you serious??? i might have to drop that line now....lol

 

No!, I was just joking, and making a funny name like one that ASUS would make... Hah.

 

shoot...you never know....lol

 

Agreed, maybe ASUS is watching this thread right now, and starts to manufacture the EXEE PC... creepy!

 

I'm currently using 620/1550/925 with no issues. I flashed the card to 600/1500/900 with the higher voltage.

I can go higher, but it seems unnecessary at this time. It's definitely not going to get anywhere near the clocks we see from 280M users. I don't see it handling more than 950MHz on the memory.

Something like 640/1600/950 is what I estimate as the GTX 260M's max ceiling.

 

Close enough, I can run 630/1575/975 all day long, but I usually run the memory at 1000. Some games I take it to 975. 3dmark06 is has been ******, but 650/1650/1025 is about as high as it goes.

 

i haven't tried over 950 on the memory yet. but i can push my shader 1650.

can someone explain what's a driver faulire and it is ok, or not.

 

Well, if you were in XP this would most likely mean a BSOD.

Usually is when your video card becomes unstable and crashes. Bottom line is ... no, it's not OK, especially if it happens regularly.

 

it happens when your clocks aren't stable and more so with a driver that has unforeseen issues.

 

My desktop 8800 GTX has some occasional driver failures. I think it is the gpu stopping after it reaches a certain temp (85c I think). But it can happen for other reasons I think. I don't think it is really really bad but maybe drop down the OC
I wouldn't suggest running a card for a long time with some of these failures happening.

 

so basically, drivers will impact jow high/low you can overclock?

 

exactly!!
this is why we test drivers...not all drivers work well with a card...if they did....they wouldn't make any more drivers...

 

well i know temps are good. didn't break 76c yet. what is the downclocking temps are and dangerous temps to avoid. my 8600 was failing and it wasn't no where near bad temps. and my 3870 crossfire hit 85-89 on normal conditions.

ok thanks. i will now be on a downloading spree for drivers. lol.

 

what driver are you using now?
maybe i can save you some time...

 

for vantage 185.85
i am using 186.03 right now.
186.18 is crap for benchmarking.

i was going to try 150.15 but didn't get around to yet. what drivers you recommend.
