overclocking a Core Duo

Hi I have a 1.83 ghz Core duo and Im wondering if its possible to overclock it? I have overclocked before but on in desktops never in notebooks. If it is possible could you suggest some good programs and safe Settings to switch to?

 

i think you can ... but heat will be a major pain in the but... not like on a desktop where you buy a better heatsink

 

All the core duo's use the same amount of power and I believe are basically the same processor, just with different clock speeds. So your 1.83 and my 2.16 are the same processor, mine just has the capability to clock higher when more power is needed. If your laptop is sold with the 2.16 as an option, then I wouldnt worry about heat. Plus the Core Duo's really dont creat a ton of heat, nothing like Pentiums.

 

yeah even with stock clocks and as5 notebooks run hot. being as though all yonah chips run the same ( minus the low voltage) then you could essentially overclock to 2.33ghz and keep the voltage the same. but it will run considerably hotter. so I wouldn't recommend doing any overclocking in a notebook. better to leave that to a desktop in my opinion

 

Why would you need to overclock your CPU? Unless you're running full tilt (rendering/encoding), then there will be no difference between and 1.83 and 2.16GHz. Most of the time, the Duo runs at 1GHz to save power anyway.

 

Hey I have a Core Duo T2400 in my laptop and doesnt get that hot at all. I can actually keep it on my lap confortably, the fan isnt barely on at all, unless im gaming.

 

Well yeah my laptop runs cool while im not gaming too, all notebooks do. But when im gaming, and my CPU has clocked up and my GPU is running full board it gets very very hot.

 

I am running it at 100% the GPU to, The notebook gets to 70C when running like this, I have the heat overload set to 85C To prevent the notebook overheating, So How do I overclock it? in my old desktops ive always just done it through the bios or through gigabytes program for this but theres no option to to change any of these settings in the bios.

 

Download NVTweak (coolbits). Open the program and then choose what ever you want. If you want to over clock then have it show "clock frequences". After you enabled it open the nvidia control pannel and there will be an option for setting clock speeds. 80C sounds like a very low threshold, mine is set around 110 I think, but it never gets anywhere near that high. If your going to overclock your going to have to increase your threshold limit.

 

IF you really want to overclock (i guess just for the cool factor) then go ahead. If you want to overclock to actually improve some performance, it would only be graphics related, and you would overclock your GPU's core/memory speed, which is set default at 300-400mhz for the Nvidia card. Take small increments up - by 2 or 5 mhz and 'break' the new speeds in.

 

My W3J with T2400 at full Load (Prime 95) for 4 hours (both cores) reaches a peak of 81 degrees celcius !!!!!!

insane.... My watercoolled rig only 40 degress MAX

so... overclocking is kinda like suicide for my W3J

 

Hmm? I dunno

 

The W3J is a small notebook. Therefore it will run much hotter than say, a 17" laptop with the same processor and all the same hardware.

Plus, laptop hardware is designed to withstand much higher temps than desktop hardware.

And no way is a thin little laptop with a tiny aluminum(or occasionally copper) heatsink with minimal airflow compete with a desktop watercooling system.

Also, just to let you know, a lot of desktop processors at stock with stock cooling will hit high 50's to mid 60's C. And don't forget, your hardware temps are entirely dependent on the ambient temperature. My Z96 with a T2400 hits 70C under max load, both cores and X1600 under load. I mention the X1600 because in the Z96, it is connected to the same heatsink, and therefore heat from it will build up along with the T2400. This results in additional heat to dissapate, which means that some of that extra heat will be transferred to the other part. Say my CPU was idling but my X1600 was under full load. My CPU temp would still shoot up. Not nearly as much as if the CPU were under load, but it would still get much warmer.

 

so how do you overclock the core duo?

 

I've never seen or heard of any laptop overclocking except for a pin-mod.

You really aren't going to notice any performance gains... unless as someone said before, you are a multimedia freak and do lots and lots of encoding and such.

 

And I said JPZ That is the case.

 

What? I have no idea what you just said, or what you even intended to say. Please expand.

 

Clockgen...

It wont work in every laptop, but in ones which it does, you can overclock the cpu.

 

overclocking a notebook is just plain a bad idea, and the payoff vs risk factor doesnt make it worth it at all, I'm all about overclocking desktops sytems, I have a 600 mhz overclock on my amd 64 x2, but its in a nice roomy case with a freaking huge heatsink(zalman cnps9500), and it reaches around 45 c full load on a warm summer day, the last thing you want to do to a laptop is add more heat, desktops and notebooks are completely different animals when it comes to overclocking

 

JPZ I have said earlier it is encoding tasks that I am doing. I tried clockgen but I can't seem to find the clock generator for the Intel 945 board so I cant get it to work.

 

Haha. I looked through all the posts in this thread and you never said why you wanted to OC...

Anyway, my suggestion is that you wait another month or two, then you go out and get a Merom(wait a second... does your notebook even support the Merom?) and sell your T2400. If it is not Merom compatable... try and pick up a T2600 or something and sell the T2400. You're just not going to be able to OC it.

 

"I am running it at 100%" Sorry your right I didnt specify which Apps im using but i am running it at 100%. My notebook looks to be merom compatiable, I might wait and just get a new notebook.

 

OK. What I said before still stands. If you can't do what you want on your laptop, you have three choices.

1. Upgrade the CPU on your Sony.
2. Do the work on your desktop whenever possible.
3. Get a new notebook.

If I were you, I would verify the Sony to be Merom compatabile, wait a couple months for Merom prices to drop, and throw a T7400 or a T7600 in the laptop. Also, I would use the desktop whenever possible, regardless of what processor you get in your notebook. I'm sure the AMD 4600X2 owns. Have you tried overclocking it? My 3800X2 OC's from 2ghz to 2.6ghz no problem. Some people have hit close to 3ghz with the 3800x2. I would imagine the 4600x2 to overclock fairly well as well. While the 1.83ghz core duo in my Z96 is fast, my 2.6ghz 3800x2 is just so much faster.

 

I just emailed the dudes over at CPUID and asked them if it possible to support the i945PM chipset. You guys can try and email them and maybe when they see there is enough support for it, they'll do it.

I also found this:

http://www.idt.com/?id=1110

I think those are the PLL chips Intel uses in their notebook chipsets.

 

Those look like the PLL chips that are to be used in intel's next-gen processor line.

 

Hmm, well there has to be a way to find out which ones they are currently using.

 

Anyone want to volunteer a sledgehammer and/or yonah chip? I'll see if I can find the PLL chips after I've had my fun destroying the procesor. Haha!
