My Geforce 8400M GS Overclocked - Question.

Hello all, iv been searching around for quite a while, and i've succesfully overclocked my card, the core settings was 400MHz and memory was 600MHz.

iv overclocked core to 640Mhz and memory to 930MHz... anything higher i get artifacts.

as this is my notebook, iv heard alot that doing this will mess up my lappy.. but my temp of the card at it being overclocked is only 61 degress C and in game it doesn't go over 75 degrees... so surely this is stable?

this card isn't designed for gaming and i wanted to get the most out of it, now iv overclocked it i am managing to play a lot of games about 35% better than before, gears of war runs at 30 fps, drops to about 22 in big places.... im over the moon, but i was wondering, is this safe?

my specs are:

Core 2 duo T5500 (1.66GHz)
4GB Ram
geforce 8400M GS

 

as long as you don't exceed 80 degrees you're good

 

Your OC is quite high. I recommend you bring it down a little, your really pushing it.

Temp monitors only show the GPU's core temps not memory temps. Memory is the one that usually fails first, and you usually get permanent artifacting all over your screen.

How did you manage to get 640mhz core speed? Mine maxes out at 600

 

Thanks for the replies.

I'll bring my memory down some then is there any monitoring programs to monitor the memory clock at all?

to get to 640MHz, first i used RivaTuner which i could only max out at 600, so then i got nTune, which allows you to go further...

 

Ah i see. Im not a big fan of Ntune.

No, theres no on-board temperature monitor for the GPU memory. You will have to use the ACPI Thermal Zone temps as a close estimate

Artifacts/graphical anomalies is a sign that the memory is overheating. Thats why some people that burnt out their gpu's experience permanent artifacts on their screen.

 

Hi my frist post on this forum. I just had my Dell XPS m1330 Geforce 8400m gs fail, so Dell replaced my MB. Ok,, so now I decided to watch my GPU core temp. and get a reading of 67c when idle and I hit 100c when I load Combat Arms with all the whistle. I am a bit confused as to what is normal and what is Hi. Also I have to add that everyone who posted thier core temps never said what environment there in. I am runnig my lappy in the Caribean in a room with a fan. Could be the issue. Would like to know the groups opinion.

 

Yes: Nvidia system tools 6.02

use this for overclocking, adjusting color settings, monitoring temps, memory usage, cpu usage, gpu clocks, etc.

 

Environment plays a major role in determining the temps. of your laptop's internal components. Since the Carribean has a tropical climate, I believe those temp. readings to be normal.

 

I live in Honduras, I also play in a room with a fan...
My processor temperatures are around 45 C Idle, 50 C websurfing
And go up to 60~70ish when gaming...

My gpu stays around 10C more than the processors...
50 C ~ 60 idle, etc..

Here in our countries, weather plays a major role...
(oh and by the way im stating a m1330 I got for my mom, NOT my m1530)

 

flipfire is right dark, memory doesnt have temperature monitoring software.

thus that might fail fast at the clocks your at...900...wow

 

i8kfangpu 3.1 does, it checks it all....
