Have you overclocked your mobile GPU for quite a while?

I'd like to know how's your mobile GPU now. Especially if you're using mid-range card who has good OC capability.
My ASUS A8Js with GeForce Go 7700 has been going above 90C when gaming for couple months until I resolved the problem, but it doesn't seem to die anytime soon (about 3.5 years now).

Now I'm considering to overclock my Sager NP5125's GT 330M for playing more demanding games, a max heat during load of 85c shouldn't be too bad, right? Considering most gaming notebook's GPU can reach around that number or even mid-90

 

@VZX - I OC my m11x Nvida 335mGT all the time. stock is 450/790 and I usually stay at 550/875. I will push it to 600/900 +/- if i am benchmarking.

My cpu temps never get above 68c.

I kept my hel80 at a +100/+56 (7600 didn't like you screwing the mem too much) oc for 3 years and it is still running fine, though it's retired from gaming

 

I oc my 8400 mgs from 400/600/800 to 510/750/1020,to make it stable,i remove the bottom panel.Game fps have also considerably improved.BTW its a m1330

 

On battery, I set Powermizer to keep it at 2D low power clocks, while on A/C I set it to be on demand. Playing games on A/C, it maxes out the clocks to my OC (in sig), but on idle, it uses the same clocks as on battery. Been 2 years now and still going well.

 

You should constantly keep it forced to 2D--even when overclocked.

2D generally uses lower voltage, so you have the benefit of your GPU running just as fast after overclocking, but running a whee-bit cooler and using less power .

I have not had any instability problems running under 2D Performance even with OC.

But I'm using RivaTuner, not Powermizer.

 

Hmm.. I see most of you only go for +100 for core, though you still keep the memory speed at low increment.

Thanks for the replies

 

I use NST's profiles to only overclock when I need the extra juice - gaming.
Otherwise, I'm running at stock clocks.
Temps have yet to go above 80 at any time I've seen.

 

you can see in sig what happened to mine from OC

 

I don't overclock any more (GeForce 8 precautions), but when I did fairly consistantly, I usually ran 575/400, instead of stock 475/400. My card didn't like the memory clocks being modified, either - really slowed down the computer whenever I quit a game - so I left that at stock. I occasionally used 590/400 or 595/400 in game. The highest benchmarking clock I have recorded is 596/400, although I think I did use 600/400 at least once (it may have been in-game rather than in-benchmark). At no point did I notice any artifacts. The highest memory clock I've ever run is 440 MHz, during a CUDA experiment a few months ago, with a stock 475 MHz core clock at that time. No ill effects were noticed.

Card is a GeForce 8600M GT DDR2. I'm convinced it will give up the ghost someday, but it hasn't yet.

 

Actually Powermizer is pretty useless in Win7 (didn't change things for me), I just formatted my laptop yesterday and edited the values in the registry for setting clock rate today. I'm going to read up on Rivatuner and switch to it shortly plus maybe play around with Nibitor and possibly downvolt when I feel comfortable with the program. Did you follow any guide (I have myDooM's Rivatuner guide bookmarked and Groove's undervolting guide bookmarked but haven't had the chance to read them and test things out) or have any tips?

 

I've been using my 3650 overclocked to 725 Core, and 575 Memory from it's default 600 and 500. It's been running at those speeds during gaming for about half a year, and I have had no problems at all so far. The maximum temperatures I have seen on it during gaming are 71C, and it usually sits around 65C during gaming, up from 63C at default clocks. This is of course, in my Toshiba.

 

How long/often have you been using it in OC'd state?

 

I have had my 8800m GTS run at 600,900,1500 at start up for 2 years. I only push it further for benchmarking. I also had my 8600m GT ddr2 overclocked all the time but it only lasted 10 months before it died.

 

I run my 5830 OC'd for some gaming. Go from 500/800 to 575/1075. The main thing you want to do is monitor the temps. Mine never gets over 73C. It's not the overclocking that kills a card, it's the temperatures. And each card and system is different, so you can't ever count on any kind of overclock.

 

Dell Inspiron 1720 - 8600M GT DDR2 @ 640/1280/525 BIOS flashed, powermizer disabled 24/7 for 2.5 years... (Wait, it's August now; 2.6 years) 5 hours of gaming everyday; Crysis, SC2, L4D2. (Younger cousins now dominate this machine ) Max temperatures of 65*C. No coolers and no room air-conditioning. No sign of failure, no sign of artifacting, no sign of going over 70*C; crying for more games. Inspiron 1720 has a Rock solid cooling and proud of it.

EDIT: You know at times I do wish it comes with a more powerful GPU during the time of release; like an 8700M GT or at least an MXM Type 2.1 and have a luxury of a HD4650/4670 modified but as always Dell has chosen to make it a proprietary design instead.

 

lol urs way always crap so u had to OC.. anyways , u only said , it was about to die and u kept ocing.. anyways , RIP crappy HD2600

anyways , i OC my GPU with no problem as u look below.. temps under 80C so i'm happy.. of course i've done a lot of mods.

 

That is very impressive. I bet if my 8600m gt ran that cool it would have lasted longer.
