Nvida Geforce Gtx 680m

[rmutua]

I just got my Alienware m17x R4 like maybe a week ago now. And i have like 2 questions about it. 1) Whats a safe operating temp for the Nvida 680m and whats a good safe/stable overclock for it. (I need numbers so i can replicate them using msi afterburner) currently ive overclocked the gpu clock from 720mhz to 854mhz and clocked the memory from 1800mhz to 2300mhz (the boost on the gpu went from 758mhz to 893mhz) When running furmark for 1 hour the hottest temp i got was 71 degrees Celsius and i idle at like 52-55 degrees. so im wondering is that too hot of a temp?
2) i currently have a i7-3820qm in my m17x is it worth overclocking? Like what are the benefits if i do overclock it and what would be a safe overclock for it

*These temps where taken using Furmark, GPU-Z, and Msi Afterburner. I wanted to make sure i had more then one temp source readings

71 during furmark is quite cool.

ok thank you im really new when it comes to overclocking so i get overly cautious. my main concern is: isent increasing a coreclock by 135 mhz alittle insane? like msi wont let me go higher so im thinking maybe this gpu has a lock on it which i am glad it does. also wth does memory clock do. like 1800mhz to 2300mhz seems like a big jump to me :/ . anyone know what temp i should stay away from? cause i like anything above 71 seems scary to me.

Many people have clocked the 680m upwards of 1000 core and 2500 memory, you are not hurting anything.

Just FYI though, Keplar cards automatically throttle on Furmark to protect the card from damage, so it really is not a good test. The best thing is just to game.

The main issue you can have is clock bouncing, where the card automatically lowers the speed over and over for a few seconds before putting it back to normal. If you don't have that then you are good to go.

You are basically fine until you're getting above 90C - in fact safe operating temps often go up to 95-100C, but 90C is a sensible upper limit so I think you will be fine with your reported temps!

I have an old Dell XPS m1530 with an 8600m GT which is overclocked and it has been running at 90-95C for almost 4 years (and it's still going). My 680m gets to a max of 89C when overclocked to 854/2300 but only in certain games (Crysis 2 is one).

In most games this card doesn't even break 80C for me

Ok thanks cause the game im playing right now is the witcher 2 and when overclocked i get 65-75 fps withough v-sync in avg areas and like 58-62ish in like areas with alot of people. my max temp with that is 66 degrees after 4 hours. I thought this game was sapposed to be hard to play on laptops and pcs but i guess i was wrong

It is, it's just that the GTX 680m is a powerful card, especially when overclocked. Alienware computers have great cooling as well.

This is what i got when i did the 3dmark vantage thingy have no idea if its good or bad or wth the P is for.... if someone could tell me what numbers i should be getting that would be great *PS if someone could tell me how to resize pictures that would be nice because having this big image is annoying and i think it might lag people if they have a bad connection so sorry :/

[paul2110]

That vantage score (P means you ran the "performance" benchmark) looks about right for your CPU/GPU with the overclock - IIRC I get around 24000 but I have a lower spec CPU.

In response to your question about overclocking the CPU - I really wouldn't bother, most games are far more dependent on your GPU so I doubt you would see any significant framerate differences by oc'ing the CPU.

That's a nice 3dmarkVantage score rmutua!

Would you mind running a 3dmark11 benchmark with MSI AB monitoring GPU utilization, temps etc. Most of Dell 680m users got throttle issues when they overclocked their GPU but you don't seem to have any !
