Mobility Radeon 4650 GPU temp (DV7-2000). Problem.

Hey everybody.

I've got HP dv7-2043cl laptop. I want to find out what max GPU temp do you guys get, when you put stress on the graphics card. I am interested only in DV7-2xxx series with Ati Mobility 4650. Mine is around 46-48 when idle. Temp goes up to 70-74 in around three minutes when I run the Fur Mark stability test (1600x900, MSAA 8x, post processing and xtreme burning turned on). Clocks are at stock frequencies.

I wouldn't care about the temperature (it is not actually that high), but I have a problem. The computer just turns off when I play some games. For instance, if I play Fallout 3 at ultra settings (1600x900, 8x msaa, hdr), the computer powers off after a couple of minutes. Same thing with Crysis Warhead at high setting (1280x720, no msaa), even Half-Life 2 at max settings! When I lower the resolution in Fallout 3 to 1280x720 and MSAA to 4x, everything seems to be fine. Same thing with Half-Life 2. No similar luck with Crysis though. Looks like Crysis utilizes every single bit out of the GPU in any case.

So... Any ideas? Advice? What might be the problem? Anyone can provide their max gpu temps?

PS
BTW, no crashes in Furmark.

PPS
I would like to check other temperatures as well, but HWMonitor doesn't support realtime logging to file. And I need constant logging to file. I can't see the temps otherwise. Any similar software out there, that can log to file like GPUZ?

 

Looks like we have an overheating problem here. The current crop of GPUs all claim to have a temperature tolerance of 100-110C on an average. First make sure the surroundings are well ventilated. And don't overclock your notebook GPU. If problem persists, you have no other option than to contact HP. i suppose you still have a warranty as the laptop sounds relatively new.

 

To answer the GPU temps question, I have a DV7-2180us and had a DV7-2040us, these two are pretty much twins with Q9000 and ATI4650. The GPU's idle about 45-47C and the highest I have seen under stress is 75C although 70C is pretty common.

Since the CPU and GPU heatsinks are a single unit, stressing the CPU using Prime or Linx, etc. will cause the temp to increase on the GPU even though it is not being used. That probably wasn't useful information.

I wonder, since the notebook just shuts off instead of crashing, if it is having a power problem. Like something is tripping the overcurrent protection or the power brick is not all that it should be. When it shuts off, does the light on the brick or the led light where you plug in to the notebook go out or stay on?

 

That's right. And mine is just around 75. So, i guess, it's not GPU's overheating.

Thank you very much! I guess my gpu temperature is all right.

What about other temps? Idle and under stress? These are mine, when idle:

 

My dv7-2135eo (P7350, HD4650) has the following temps:

cpu idle: 41C
gpu idle: 49C

cpu load: 50C (wprime 1024 test)
gpu load: 62C (furmark)

cpu load: 54C (1 hour crysis)
gpu load: 65C (1 hour crysis)

Looks like SSWilson has a point - when stressing both the cpu and the gpu at the same time both gets hotter than stressing them separately. All in all the P7350 seems to be a rather cool cpu.

 

Here is what I look like after 15 minutes of 64bit Prime95 small fft's. Normal use I see idle around 40C-42C and load up to around 70C. This is with fan set to always on in bios. The fan ramps up pretty aggressively when the CPU or GPU reach about 70C.

Of course, you really can't compare my CPU temps to yours since the CPU's are so different. I don't know if the heatsink in my unit differs from a dual core. We really need someone with a T6500 for a good comparison.

 

Don't worry.. furmark stresses GPU too much so don't worry... games will make its temp lower than 80C ... my NVDIA cards runs 80-82C so don't worry....

 

Thanks for your replies, guys.

So I've managed to heat up my Chipset/CPU/GPU up to



by running FurMark and IntelBurnTest simultaneously.

The computer didn't shut down. So why the $#@% does it shut down when I play games?!

 

How come my idle CPU temp is 5 degrees lower under Win7 compared to WinXP?

 

I do believe that your CPU and not your GPU is causing these problems.. try undervolting.. search for the undervolting guide in the forums.. then buy a notebook cooling pad like the zaltman NC2000... and lastly apply new thermal paste to your CPU and GPU... should have no problems then.. your temps seem to be allright... my CPU used to go to 95-100 celcius yet my comp nver used shut off.. quite weird.. try all of this and see if it works.

 

The problem is definitely with your CPU, like sean said. 75C is fine for a graphics card but 90C is way too hot for an Intel CPU. You should definitely undervolt that processor.

 

I'm gonna replace my CPU for some intel P model. Any advice on what is the best intel P cpu at the moment considering price/performance balance?

 

P series CPU might go up to the same almost(3-5 Celcius difference). Unless your old CPU was crappy like a T5800 , no point upgrading.. try undervolting... it should reduce temps by a lot my processor's temps dropped by 10C with a little undervolting.. if i undervolt more, it will drop even more,..

 

Yeah your CPU temps are pretty high and even for a intel processor i know HP laptops are known for their bad cooling systems but is just bad because intel CPUs shouldnt even reach to temps like that. Anyways at 90C your CPU will start downclocking when playing games causing lag and shutdowns. Like others said try to undervolt your CPU there is a guide for it here http://forum.notebookreview.com/showthread.php?t=235824

 

I would say that it should be fixed by HP.

 

Thanks for the undervolting tutorial. 13 degress temperature drop at maximum load. Lowered all the voltages to 0.9250 (max was 1.1500). Idle temperature remains the same (~55) whatever I do.

I still wanna replace the CPU for some P series CPU. T6400 is no good.

 

go ahead..T6400 is crap.. its a memron.. you can get a T9400/9600/9800/9900 and P9500/9600/9700 CPU.. those should work..

 

Hey everybody again. Has anyone paid attention to the chipset temp? It almost reached 90 with me as well. Is that too much? My idle chipset temp is around 55.
