G53 overclock with msi after burner..

hi guys. i've read tonnes of posts about oc'ing the 460m, but there's some things i want to know before i do it again:

1) Does it matter if you adjust the clocks in small amounts or just put it to a value like 700?

2) Will overclocking dramatically shorten the life of the gpu hence the life of the laptop?

3) When testing with furmark; no artifacts occur, but the temp still rises to over 90 degrees. Should this happen or should a stable OC yield a max temp under 90 in furmark?

4) Is it bad to keep adjusting the core and shader clocks, i.e does it affect the bios or anything. Can i OC to play a game then reduce the clocks when i'm done?

Thanks in advance for ur replies.....

 

Hi,

1) Nope it doesnt, however small 50mhz increment is vital to achieve your stable overclock. The standard oc on a 460m is 800/1600/1600 at least on G53SW. There are some that can reach even 850, some of the less lucky can keep 820 on core. If you want, do a small increment. Otherwise go up to 800 and test it, then tune the core a bit with small increments. Over 800 mhz on core i would advice 15mhz increment.

2) Yes and no. There isnt a real proof of it, but generally if you stress too much a piece of hardware it can shorten his lifespan. Thats electromigration. But also keep in mind that most laptop and computers components (in electronic, generally) are downclocked from their best values/max values. So in all the discussions, it seems plausible to think that OC cant short the life span of card since technically core/memory/vrms are made to run at certain speed, then downclocked.Just dont think about it,unless you do something crazy you're perfectly fine.

3) 90c under furmark means that the card is stressed on unbelivable levels. Keep in mind that hardly you can reach those temps in real gaming sessions. But anyway, the temp is a bit high. I guess you're not using a laptop cooler? If you dont, you can raise the bottom of the laptop using whatever you have in hand (some lego bricks as an example). Raise only the back,not the front. Temperatures should drop since the airflow now hits the backpanel as well.

4) you dont need to adjust clocks to their defaults or whatever settings. Nvidia drivers put the gpu to the lowest state possible when not used. Its called low 2d level,or idle mode. In that case even if you oc, the gpu will drop to 51mhz when in idle, to go back again to your OC clocks when needed.

 

Thanks so much for your thorough reply Kingpingzero, this really helps. I was just playing BC2 awhile a ago (740/1480/1250- didn't adjust mem clock) and all of a sudden it froze and i got a BSOD. I was playing at 1080 and most settings on hi. This never happened with any other game. I was playing online.
Any idea what caused this?

 

i am running my gtx460m on the g53jw on 814-1600-1628 and i have never ever experiance any shutdown or bsod or gsod or any other things.

what driver are you using ? did you update the bios ? put it on stock clocks and run the game again if the same thing happend then that means something else ...

good luck !
