To OC, or not to OC

I have a M570RU with a T9300 core 2 duo

It runs standard at 2.5GHz but i want to squeeze a bit more out of it, is it safe to Over Clock this machine, and if so to what Frequency

Full Spec's:

T9300 core 2 duo
8800m GTX gpu
4 gb's RAM
bios version is 1.00.08s
Windows Vista Ultimate OS

 

Hi and welcome to nbr forum.
if you know what you are doing with overclocking then its upto you but a lot of OEM's give a warning that if a failure occurs and its found to be due to OCing then your warranty may be invalid to cover the repair.

 

If you overclock it will increase your FSB , which means that all hardware will be overclocked (ram and video). If you are lucky you can use it without problem for a long time. If you do overclock make sure that you have good air flow around the laptop. In your case you could get max an increase of 25 %. Not sure if it worth the risk.

 

I had the T9300 before I upgraded my M570RU to 8GB ram and an X9000 cpu.

The best I could OC the T9300 to was 2.7Ghz without the system locking up under Vista Ultimate 64. It ran fine like that until I decided to do the upgrade and eventually go to Windows 7 RTM (I have a MS Technet subscription).

As always, YMMV. All the best.

 

Hmmmm well i havent adjusted fan speeds or anything like that, but i do know that the rig runs pretty hot already, ive had it for a year with no problems (knock on wood) so idk if i really want to risk it

does anyone know what the typicall factory setting are?

 

use Audigy's Auto setFSB tool. You should able to push 2.8 - 3.0 ghz depending on your chip.

just watch your temps, and dont run it that high all the time if you can avoid it. works awesome. I have my t7700 (2.4) OC'd to 2.6 all the time, and bump it up to 2.8 when I do heavy gaming or stuff for a little extra FPS etc.

good luck and enjoy.

 

I've had my cpu OC'd with SetFSB for over a year now with no problems.

 

how can they found out the graphics fail because of OC? (software OC)
i wonder.....

 

so i guess it can be done ill just have to be careful with it,

but is there that much of a performance hike with an extra 2 or 3 hundred MHz's?

oh and does anyone have a link for that fsb software?

 

do i need to get software that monitors my temp or does the fsb do that for you?

 

T9300 is 45nm chip, runs pretty cool normally, however, its given quite a bit higher voltage than required, with default value of 1.13v. Once you drop that down, it should have some space for overclocking; OC'ing normally makes the CPU run hotter, you could compensate which by undervolt it - there is a guide here:

As for Temperature monitoring, get the HWmonitor from here:

Provided you undervolt the chip sufficiently, it should not overheat. In a M1730 which I used, I got the managed to drop the voltage from 1.13v to 0.975V, which cooled the system down quite a bit. Overclocking the CPU could shorten the life of the chip, and given the 8800m GTX in the system, I assume the laptop is out of warranty?

Overclocking CPU is normally less risky than the GPU, given limited head room and built in thermal protection; though unless you really need extra CPU performance, I'd just undervolt it, and not OC at all.

Overclocking the GPU however is more risky; if not careful, you could end up with a fried 8800m GTX. Make sure you use Nvidia System Tool to OC it, increase the frequency carefully, and watch out for the temperature. 8800m GTX is a pretty fast chip itself, but also has decent OC'ing headroom - but stay under 650/950/1600 for your wallet's sake.
