Nvidia GT330M OC Settings!

post #1 of 9
Thread Starter 
I have ACER 5745G. It has i5-430M(2.26Ghz), Nvidia GeForce GT330M, 4Gb DDR3 Memory. I was thinking about overclocking my GPU as well as CPU(Primarily The GPU).
First of all is it safe to overclock on my Laptop without any external cooler?
I just want to overclock moderately not push it to extreme! I have Nvidia Inspector 1.9.5.5, GPU-Z v0.5.2 and EVGA Precision 2.0.2. Which one is better for Overclocking?
Please tell me the appropriate settings as this is my first time.I have 189.97 WHQL as it is provided on the ACER Website. Nvidia offers 267.76 WHQL. Should i use the drivers from Nvidia website or OEM website?

I am Attaching my EVGA, GPU-Z and Nvidia Inspector Screenshots.

I would reccomend the Nvidia drivers and as long as you watch temps you will be fine.

the gt330m on my vaio z clocks up to 685 Mhz core, and at stock it's downvolted and down-clocked. I don't really know how to change the voltage, but it's a pretty big improvement for me, with minimal increase in heat.

Of course, your results will vary. Just make sure the temperatures don't go up like crazy.

I use nvidia drivers that have been modded to work with the vaio z, since the vaio uses switchable graphics

i used MSI Afterburner on my ION card.....

it OCed 220Mhz over stock (400Mmhz to 620Mhz)

standard drivers are recommended

just keep a close eye on the temps...

would recommend that you use MSI Afterburner's OSD feature...

with a Temp Reading for the card...

I wouldn't go over 90Deg C...

I have only hit 70 Deg C myself...

but anyway.. best of luck...

also with laptop gaming... the CPU and GPU share the same cooling unit...

so if u OC one.. it heats up the other one...

so i would recommend OCing the GPU over OCing the CPU...

Since 99% of games are more GPU dependent then CPU dependent

and remember... most laptop CPU keep up with there Desktop counterparts...

where the GPUs don't... they tend to be a bit slower

Thanks for the info.
What do you mean by standard drivers? The Nvidia ones or the OEM Drivers?
Another Problem- I cannot change the fan speed of the gpu. you can see it is disabled in the evga precision screenshot. any way to fix that?
As the laptop gets very hot(it is difficult to handle!) , do you use any sort of cooling pad? I dont have one but Seeking to buy Logitech N120. Hope it is good!

Nvidia Drivers...

I have had alot of issues with OEM drivers when it comes to games

i don't use a cooling pad....

i don't need to... since my laptop already runs nice and cool....

but i have heard that the cooling pads do make a difference...

well the one i built myself for a mate using 4x 140mm fans works great.... (for a 17" laptop tongue.gif)

I have overclocked my GPU. What do you suggest? Is it too low or too high?
The Max. Temperature reaches 86 degree Celcius. Is it harmful for the internal Components?

86 is ok, try not to go above 90. 100 is the absolute max before you begin to damave things, but your computer should turn off at that point.
