GPU overclocking increments

I did a search and couldn't find but I'm trying to OC my GTX 260m on my ASUS g71gx-rx05 laptop. I'm using nvidia control manager.
My question is, how do I know how much to move each slider up?
Is there a certain formula to this? Do I just move each one up by 5 until it doesn't crash or give weird images on the screen?

 

are u using NVDIA system tools? If u are , i recommend that u OC the core and shader in a ratio of 1:2.5.. also don't OC memory too much.. it has no sensors and if it burns , not good... don't OC more than 10-20% on core and shader clocks... also doesn't ur G71 not have a good cooling system? If ur's doesn't run cool , don't OC....

 

Are they adding voltage with their overclock?

How does overclocking in its self without adding voltage cause it to overheat?

 

NST works for my laptop, but trying to load profiles with it causes hardlocks on login. Beware.

 

I OC my gtx 260m as Sean473 mentioned.
I raised it to 600/800/1500
the "800" was default. Should I raise that a bit?
Also, the profiles didn't freeze up on me.

 

I hope you typed that out of order. the memory is usually the last one in the order. If your memory is over 1k for too long baaaad things can happen

 

Overclocking the ram at all is just a bad idea, theres no way to regulate the temperature in laptops, just leave it alone, the small gains aren't worth a dead gpu.

 

Exactly. I leave that alone and just play with shader and core

 

Hi I'm running mine at 620/1620/950. I play crysis warhead for like an hour with max temperature of 77-78C. I also run the ATITOOL artifect scan for 4 hours without error. At default clock while gaming the max temperature i got was 67C. Is that consider a good temperature and a stable clock? Thank you!!

 

There are a couple of viable scenarios:

1. Your laptops thermal budget can take the increased heat output because it a) I using a lower GPU than a higher model, or b) has a really nicely designed cooling system.

2. You undervolt the GPU at the same time and increase the frequency. This can occur if there are large tolerances in manufacture.

My laptop is going off option 2, it does not like it in the most demanding games to overclock at stock voltage, but whack the voltage down to 1v and I am running the core at 625mhz vs the 550mhz of stock.

 

Yea I didn't touch my volt or anything. It at stock volt.

 

hmm I'm gonna have to read up more on overclocking. Not sure what my clocks are set at default in my system. Time to run gpu-z!

 

Its worth investigating if you can notch down the gpu voltage even one level. It can make a large difference.

 

lol sadly i can't undervolt my GPU... hp locked vBIOS.... my OC temps hit 86C so i don't OC for now...

 

how do I decrease my GPU voltage on my laptop though?
Nvidia tool doesn't allow me to do that.

And yes, I typed my setup out of order.

 

You have to bios flash it, nibitor can edit the 3d voltage in the bios file before you flash.
