Overclocking
(Click here to view the original thread with full colors/images)
Posted by: matt.modica
After I get my laptop cooler, I am planning on doing a little overclocking. I am new to this, so I would like a little help.
The processor: I would like to start by overclocking it to 2.0 GHz, and mabye go a little higher after. My CPU averages about 60°C (140°F), although that might change after I get the fan. I was wondering how I could do this.
I was also wondering if I could overclock my FSB, and by how much. The most I would do would be by 400 MHz.

Hi Matt!
Well. first check out your BIOS. If you have a BIOS, that allows overclocking? It must have settings for FSB, multiplier and PCI and AGP lock. Also settings for RAM speed. Preferably also for the RAM and CPU voltage.
If your BIOS have those settings?
Then this is how it's done.
1. Lower the RAM speed to the setting below the stock speed. example PC 3200 to PC 2700.
2. Enable AGP and PCI lock.
3. Now, raise the FSB from 180MHz to 200MHz ( This will give 2.0 GHz). Keeping the multiplier at the stock setting
( At least at the beginning).
4. If you are able to boot without problems? Then have following software at hand:
CPU Z, Memtest , Prime 95, torture test. And "motherboard monitor 5".
Open CPU Z, and see what the RAM speed are? make anote of that speed.
Run Memtest for 800% And after that, run Prime 95 for 1 hour at least.
But watch the temps carefully ( Thru Motherboard monitor 5). As Prime will heat the CPU a lot. Never let the temp pass 60C on an AMD! If it starts to get near that? Shut down Prime at once!!!
Thats about all. IF you have decent temp, under load (running Prime95)?
Then try to take the FSB to another 10. And repeat the testing. And so on.
If you come to a point, where the lappy refuses to boot? Then clear the CMos jumper or pull the mobo battery for 30 minutes.

If your CPU averages 60 C you might already have cooling issues. I would suggest solving those first. I understand that laptops tend to burn a lot hotter than desktops because of the reduced empty space. But it sounds like perhaps any heatsink material you have and/or fans may be out of contact with the sources of heat. Once you've fixed that issue, then I'd follow Gorandpaa's advice. He listed it pretty precisely.

Well I'm going to see how much the CPU temp is reduced with the cooling pad, and then, I'll consider it (I've heard good reviews about it, and some people have reported 15°C differences in temperature with it). But anyway, there is no setting in the BIOS to change the RAM speed, PCI/AGP lock, or FSB. Is there any other way I can do it?

Another problem, the motherboard monitor doesn't have my computer listed, and its showing 0°C CPU temps (which I know is not right).

laptops are especially difficult to OC, it seems, since they really, have very little cooling...
Posted by: goranpaa
I dont think it is possible to oc, without those BIOS settings.
And also as you can't get Motherboard monitor to work. The only temp monitor that may work then is "Fanspeed". I mean it could be nice to have a working temp monitor software, even, if you cant oc.
I also agree to what Zakir says.

Yes, probably a better idea to keep it down 200 MHz than to fry the motherboard and CPU.

OK, I found a program that will let me overclock (clockgen) and a temperature monitor (Hmonitor), which reports that the CPU is actually 62°C. So if the cooling pad can't get the temps down to at least 50°C, I probably won't overclock.

Good.
Never heard of that software until you meansioned it. And reading some about that software. It seems to be pretty reliable.
Hope you can get the temps down to a point, where you can oc your lappy now.

Also I know that some drivers allow you to oc your memory and video card, of course they are pretty hardware specific. I have a geforce go 6400 in my lappy and Goranpaa found me some drivers that let me increase resolution to a level before inaccesible and to oc my gpu and memory, might be worth looking into, also I've never experienced temps 60C in my lappy and that is with gaming, so I would try to solve that heat problem in short order or you may have larger less fixable problems in the future....

Another thing is, that if you can use a cooling pad to lower the temps to a decent level. Your laptops lifespan will be prolonged.
Lower hd temps, will also make the risk of loosing data smaller.
Posted by: matt.modica
Hard disk temps are around 25-30°C, not nearly as bad as CPU temps.
Posted by: goranpaa
That's a good hd temp.

OK, the cooling pad just came in today, and its really good! I'm seeing average temperatures of around 50°C, and they only went up to about 60°C while runing a virus scan and analyzing the computer with everest. I'm now going to try the ClockGen program.
Posted by: goranpaa
Great. Just watch the temp. Use clockgen. And then stress the cpu, by using Prime 95. If you have a temp below 60C after 1 hour, it's good.
Posted by: matt.modica
OK, Ive got the CPU up to 2.0 GHz, how do I stress it using Prime95? Temps seem barely affected, still only around 50-52°C.
Posted by: goranpaa
Just download Prime 95, torture test. And let it run. It will stress the CPU like hell.
But you also will see if the oc is stable?
If you get no errors after an hour or so, and your temps is o.k.? Then you can try some more oc if you want.

I ran the torture test for about an hour with no problems. I left the computer, and it went on standby after an hour (its set to do this), but when I came back, the CPU clock reset to 1.8 GHz. Why is this?
Posted by: goranpaa
No real idea. But maybe some safety setting in Clock Gen? Give it a new try and see if the same thing happends again?
Posted by: matt.modica
I reaplied the 2.0 GHz setting, but it still switched back when the computer went on standby. I'm guessing this might be caused by the program not actually modifying the BIOS, so I'll probably just set the computer not to go on standby automaticly, and create a startup entry for ClockGen so when I reboot for windows updates, it will remind me to increase the clocks again.
Posted by: goranpaa
That I think would be a good thing to try.
Posted by: matt.modica
The newest version of clockgen (still at CPUID.com) now supports saving overclocked settings and reapplying them at startup. Pretty useful.

I think that you should listen to Goranpaa he gives great advice and helped me to where i am today sound advice and a great listener also he does great research, by the way Goranpaa you have heard of clockgen i told you about it 4 months ago and it is a good application to use when you first start out.
G if you get this check your mail please Spartin
