Maybe it's a bit more than a slight problem, though.
Anyway, I've been meaning to ask this for a while. A month or two ago, I thought I'd try out overclocking my nVidia GT330M. This worked fantastically for the first few times (I was pulling around 20 FPS with everything on the Mafia II demo maxed, at a 1366x768 (My laptop's native res) resolution). Temps also generally stayed below 70. However, from then on, it just seems to lower FPS. A lot. When I have it overclocked now, even on medium settings my frame-rate tanks to around 5-8 FPS, and I can't quite put my finger on why it's happening...
I've stayed away from it since then, but I was wondering if anyone knew why it began to do that? Stock clocks get the same FPS as they did before, so performance of the card isn't inhibited in any way.
Yeah, heat is pretty much the biggest problem with laptops, I think.
I have it on my lap most of the time. When games though, I have this weird gel cooling mat thing that I got for Christmas. It actually reduces temps, so I'm pretty happy with it!
But, as I said before... the GPU doesn't go above 70, really. Stock clocks put it at around 62-65 degrees, so it's not that big a temp increase.
I don't particularly mind about it's refusal to overclock, it's just the fact that it worked brilliantly one time, but sucked all the rest of them confuses me!
Thank you! It seems to be quite the nice community here! Hopefully I can learn a lot.
Also, to save opening another thread... With my CPU temps, one of them always seems to be about 10 degrees higher than the other, give or take a few degrees. My old laptop had the temps around the same, which I find more believable. I was thinking that the sensors were wrongly calibrated or something, but I've never been able to find a concrete answer.
then all i can say is, you running a laptop form samsung that was designed as an alternative to an office pc who does his work on the go.
your trying to run games off a 1st gen i3 so i'm not surprised(now) that your getting lower FPS.
Now when you add these things together, you'll understand that the cooling solution installed inside your laptop was intended to cool your laptop when under light load. You may have the laptops cooling vents clogged up with dirt/dust bunnies or the thermal paste on the coolers has taken its stage exit.
sensors can be dodgy at times...but if the laptop can't handle a bit of gaming then its time for the warranty card to play its part.
I just went through Crysis 2 with the settings set to extreme.
be careful with that game...caused my gpu to almost melt the backplate off my rig...
OK, i retract my comment about it being a bad piece of hardware, though you should try running the machine in cooler environments.
OC'ing dpends on a couple of things, i'll skip all of them except the part about power delivery. Your laptop isn't designed to be OC'ed, at least not now. Thas why your getting a lag in FPS. To realize the GPU OC, you'd need to OC your CPU as well - and in turn OC your ram to sustain it. so all of that = stable OC, smoother frame rates and game-play.
Yeah, I heard about some issues with it. I just decided to quit out if the fans ever went crazy. They didn't, luckily, and temps stayed reasonable.
Hm... running it in a cooler environment isn't particularly possible. I'm stuck where I am, really. Britain has ridiculously humid summers...
Yeah, you make a good point. I was mainly just confused about why it worked brilliantly once, then crippled it the rest of the time. I'd overclock my CPU and RAM, but I have no idea how to, seeing as the BIOS has no option to.
Maybe I'll just leave the overclocking until I get a desktop. A pity that time is so far away.

for gods sake bro, that thing you have in your hand is not a swiss army knife, its a can of sardines
*open can of sardines, use it if within expiry date - dispose of if beyond the posted date
the fact that the BIOS doesn't have the option to OC is the first site that your laptop isn't OC capable - even a bios hack/swap and a bit of OC'ing would ofcourse nullify warranty. Your call though, its yours to waste or savour.
