Do you Overclock your Notebook?

Do you? I am just curious, because I am still deciding if I should. What are the pros and cons of each?

 

Well if you OC you may shorten the life of your notebook.

But you can increase performance without spending more money or having to upgrade.

 

I would only do so with an old one, being that I'm not an expert at that sort of thing.

What is the true purpose in doing so anyway?

 

I overclock my video card a bit, not my CPU though. Overclocking CPU's is pretty dangerous and much harder.

 

Overclocking the memory timings of the GPU is most dangerous. i wouldnt try doing the processor though i do have a Turion, which stays amazingly cool with a rather small heatsink. It doesnt have a big enough L2 cache to get big performence gains.

 

I overclocked my 7900gs in my E1705 to 450/1100 and got a jump of about 400 in 3dmark 06. I saw no change in my idle temps but while gaming for long periods of time it gets a little bit hotter than it used to. I'm happy with it, 350/1000 (what it was stock) was a little low for this card. I would never try OCing the CPU, don't really need to with it being dual core and all, it keeps up fine. In a few years I might consider it just because I'm sure I have plenty of room as far as temperatures go, it has never gotten about 30 degrees C even during/after gaming.

 

I overclock the X700 in my notebook significantly. It has been running that way for almost as long as I have had this notebook with zero problems.
The normal clocks for it are 351MHz core, 331MHz RAM; I overclock to 410MHz/400MHz and can go a bit further if I wish. That overclock nets over 3,300 points in 3DMark05.

On a related note, I also underclock my processor.

 

I OC'd my celeron today and it went from the "Stock" 1.4Ghz to 1.86Ghz!! I'm not 100% sure how it works (well i put a jumper in 15th and 16th holes on the 3rd row and it tricks the MB into cranking up the multiplyer so thats how I got a 400Mhz+ increase!)...And I can def. see a difference!

 

Would only ever overclock the GPU, which I did.

 

Keep an eye on the temperature of the CPU for the next few weeks, of course. You could run into problems because of that. You should ALWAYS know what it does when you do something like that, because otherwise you could easily end up burned.

Read this page to see what it does. It essentially overclocks the FSB to 133MHz instead of 100MHz, and the CPU multiplier says the same. So you were wrong on that, and lucky that your memory works at the higher speed.

 

No, I would rather under clock my CPU as stable as possible.
A cooler Laptop will give me longer battery life and system life.

A laptop for me is doing the job, not risking the investment.

 

I overclock FSB by 5% getting 1,86GHz Pentium M up to 1,96GHz which is faster than 2,0 GHz Pentium M .

x700 from 350/300 up to 415/435 without any problems scoring 3200 3dmark05 instead of 2170.

I also undervolt my CPU getting 10 degrees lower temps while playing (with overclocked GPU of course)

So, we are pretty much in concensus that overclocking the GPU is a lot safer than the CPU, correct?

 

Easier. And you get much better gaming results. The point is in getting a faster comp at lower temperatures. Not "the fastest" possible computer with lots of BSODs. And heat is enemy no1 to CPU and GPU.

 

How is 41C for a temp? I think its not too bad, I used some after-market artic silver (well very similar too) thermal paste and it seems to be stable and no errors or bsod's and the heat from the fan seems to be the same as it was before, I just never got the temp of my processor b4 this OC so ive "googled" temps for this proc. and seems to be within limits but whats your opinion?

 

41C is usually pretty safe range. What about under gaming load? If it starts going upside of 50-60C, then you should start worrying. It sounds safe as it is though. Didn't mean to scare you too much, but I've seen enough people burned by doing stuff like this when they can't afford to get a new processor or computer should the overclock fail that I don't like letting people do it without them knowing the possible consequences of their actions.

 

I'd say 90 should worry you. 50-60 is just ok if you have a CPU and a GPU under the same heatsink for example. Gpu is heating CPU actually while gaming. So from my experience some notebooks are just around 50 on idle or in windows. Some reach 80 while gaming with no problems at all. But I agree with Pitabred, that the heat is a problem. Especially in notebooks.

 

During heavy gaming my CPU goes up to 70C and idles at about 58C. There's no way, and I'm not sure if I wanted, to know what's the GPU temp. It's propably a lot higher. My GPU is running at the stock FSC underclocks (sig), while ATI defaults for X1800 would be 450/500.

There might be some dust blocking the air flow. It's been over 2 months since it was last cleaned..

 

Yes. I put an 11% overclock on the CPU by increasing the FSB from 200 MHz to 222 MHz:

CPU: 1800 MHz to 2000 MHz
FSB: 1600 MHz to 1780 MHz
RAM: 333 MHz to 370 MHz

 

I don't think there is much point in overclocking my laptop. It gets very hot after around 3 hours of intensive gaming anyway.

 

spilling liquids is the #1 enemy of cpu and gpu

i OC my gpu from 430/400 (i think) to 570/450. (its a x1400)

got an increase from 1955 to 2339 in 3dmark05

but that doesn't translate to real games though

heat tops out at 60C over hours of play

don't overclock my cpu (2ghz core 2 duo). i think it does what i want pretty well

 

Is it a simple thing to over/underclock a notebook? Can you change the voltage often (like every couple weeks)?

 

Actually voltage is changed everytime a different multiplier in Pentium M is used. Meaning theoretically every 1/2000 of a second.

Overclocking and underclocking GPU is fairily simple on Ati and Nvidia GPUs. CPU is another story - if you get the right software or BIOS settings it is also simple, but otherwise it could be very hard. Undervolting Pentium M is very simple.

 

I don't game and my cpu is more than capable of coping with the few apps i have running in windows so there's no need.

I tried overclocking my x200m from 378MHz to 459Mhz and it was stable, but as I don't game I underclocked it to 309MHz for basic tasks.

Is the process for undervolting a pentium-m the same for a celeron-m and does anyone have any links to how it can be done? Does it increase battery life significantly and how does it affect cpu performance? Thanks.

 

any1 tried OC'ing the core 2 duo processors before?

 

Check my sig - it could help you. Search NBR for undervolting and overclocking - there is some good stuff here.

Ivan

 

Ok i checked and it seems like a Celeron-M can't be undervolted.

Thanks

 

If you are going to overclock the CPU you really should get a cooling pad. The Bytecc one is good. I use that and temps never go above 60 degrees.

I haven't, but it is possible. What laptop do you have? What is your chipset/northbridge?

 

Would you need that if you were overclocking the GPU?

 

hm... Is it possble to overclock Core Duo processor?

 

.

Thats what I wanna know and how??

 

I don't OC --- don't feel the need too.

 

I've thought about pin modding my cpu into the 2.0g range. But like most everyone else my 1.5 does what it needs to do. I just surf the net, run Office apps, and email.
At one time I think Ubergeeks would rate themselves on the speed of thier machines and the amount of hardware they have.

 

i dont need to or want to 2 ghz is enough for me

 

well i think overclocking anything when you dont or will not need the speed at some point all you do is pin mod it and use the likes of nhc or rmclock etc to underclock and undervolt it the rest of the time so it runs with all fans off completely

well thats the route i took with my pentium m dothan at [email protected] when it needs to and 800mhz@ 0.7v the rest of the time and ive had it priming for 4 hours and not a hicup and thats alot longer than any time it would spend at full speed anyways so im happy with that.....until i get my core2duo rock laptop

 

I change the clocks of my my ATI x300 in my laptop by both overclocking for gaming and underclocking to prolong battery life. In addition, I undervolt my CPU to save battery life as well.

 

just my gpu thus far.

 

I'm thinking of overclocking...any ways to do it? My chip's a Merom T7200.

 

No and I don't need to. Plenty fast enough (core duo). We have a 2yr old P4 in the desktop back at home. Ha!

As for the GPU, my laptop gets sorta warm on stock (425/378 - I know *way* below what X1600 is at "default"), but my games run OK

 

Considering a 2.0 C2D is a quicker processor than my desktop's Opteron 165 @ 2.4ghz... no, I will not need to.

 

I got my Turion TL-50 @ 1.8GHz 24/7, up from 1.6. Not a big increase, but considering that even at the OC'd speed I'm still running less volts than what the computer came with originally, I'm happy.

Also, my I OC the gpu too to 450 core up from 300.

 

I recently overclocked my Acer, as per my sig, from 1.6ghz to 2.2ghz (~37% increase) with Clockgen. It's quite noticeably faster, and with NHC on a dynamic setting (throttling between 830mhz and 2.2ghz), temperatures are pretty much the same as before. The only tricky part was figuring out just how far I could raise the clock. Eventually got it through trial and error. I would recommend OC'ing. I plan to do it with my 17" Gateway when it comes in this week.

 

well,I have never OCed a laptop and I don't plan to do so anytime soon. I'm too worried I'm going to mess something up or at the very least have heat issues.
If I ever get that DT I've been Dreaming about, perhaps I'll OC that since I won't have to worry about heat if I LC it.

 

are you using clockgen?

 

no i dont ever want to try overclock notebook because I don't really need to cpu power of a notebook. I try to run 600mhz on the pentium M laptop so laptop cannot overheat. Using max power cpu laptop cpu temperature will be
70 degrees celsius

overclocking will just gonna lower the life of the notebook. desktop is fine because you have cooling components to prevent that.

 

I tried. I only upped my celeron M from 1296 Mghz to 1350 Mghz, and smoked the MOBO. I went from 99mghz on bus to 104mghz. I did drop 10 sec. off my Super PI score before it went into eternal sleep mode. lol.

I would use caution doing this. jmho. I think I'll stick with desktops for overclocking.

Leon

 

Yes clockgen. I got the info about the correct PLL from another member on here who found it by a simple trial and error. If you can't find the pple on google for ur model, just simply go thru all the PLL's and then click "read clocks" and if one's the right one it will display all the correct clocks, for the cpu, memory, fsb etc.

 

Heya Andiu did you use ClockGen to OC your viedo card as well? If so how do you do it ? I have used it to oc my processor for my laptop but I dont see the option for the video card. Thanks again for the help.

 

No I did not use that program because that is strictly for processors.

Instead I used a little program called "WinCLK". But I don't know what gpu u have, so u can try using ATITools, or RivaTuner.

 

Thanks again for the info. I have the ATI Xpress 1100 same as you? What settings would you suggest I use? Sorry for all the questions but I'm really new to this and dont want to mess up. Thanks for again.
