Where is the shader clock ? HP dv2700 / 8400M GS

Hi all,

I have been reading the threads related to HP notebooks with defective nVidia GPUs and just out of curiosity, I checked the 8400M GS GPU in my roommate's HP dv2700 notebook, which normally runs @ 80 - 90 deg C, using GPU-z software. The sensor data matched the default core / memory clock for 8400M GS, when under stress. But I got confused when I saw that the shader tab is disabled .



I do not know if somebody else has already come across this situation. I searched here and could not find a similar reported problem, hence this thread. Am I missing something here or is there someone out there having the same problem. Can it be something related to an older ForceWare version (156.65)? Interested to hear from you guys ...

 

well, looks like there is no one else with the same prob ...

Had a look today at the HP customer care site, where they have catalogued the defective product series which are entitled for the free repair and extended warranty. From what I read about the way HP is handling the problem, I am not surprised to see that dv27xx series is not listed under the category "eligible for free repair". Here is the link, in case someone doesnt know already -

Anyway, my roommate's machine is not exhibiting any of the symptoms mentioned in the webpage, but the way I understood things, it's the overheating GPU (8400 GS in most of the cases) which is the root cause for everything. My understanding should be really bad (according to HP) ...

 

your temps for the gpu are high very high i have a dv6000 series to be exact its a dv6871us with same gpu and it doesnt reach that high my max temps for it are 70c-75c. those temps are after i play call of duty 4 at medium settings.

 

Yup, this is another defective 8400 GS from nVidia. After I cleaned the airvents, the temperature rarely goes above 90 deg C, except while watching HD movies. Under stress the temperature is still above the danger zone. Nothing can be done anyway, the laptop is out of US now, and HP does not consider this as a defective model.



The main problem mentioned in the thread is solved by downloading the latest GPU firmware from the HP customer service site. Now the shader clock is visible.

 

Why is your memory 200mhz faster then mine? Are you over clocking it? By the way this is the 8400m gs in my dv6500t

 

Woah I just noticed HP put gddr3 memory in a dv2000????? Since when did they do that?

Which BIOS version solve shader clock?
You are referring as firmware that packed in BIOS right?

 

I never had a shader clock problem. And i have no idea what bios im using. it says unknown in gpu-z. If your referring to system bios i have f.59

 

Thank you, Tippey764.
So sorry, for the confusion, that questions were meant for Comskian.
I was going to add comment gdd3 memory, and put this link http://forum.notebookreview.com/showthread.php?t=205671

Hi rief,

the shader clock problem was solved by updating the GPU driver from HP customer care site, as I mentioned in the earlier post. I downloaded the latest driver released for my specific laptop model.

Regarding DDR2 and DDR3 memory in 8400 GS, this is a new information for me too!

 

Hi
the problem is that there is a huge gap between the gpu and the heatsink and it is filled by some soft material..i replaced it with thick copper plate which lowered the temp to 55c. i also reduced the clock. the thick copper plate is available in ebay. reducing the clock also reduces power consumption and hence the temperature.

 

There is no real reason to reduce the clocks, as it isn't that (nor heat) what damages the chip.

It is the thermal shock caused by starting up in a cold place which cracks the solder. My DV9700 would boot with the "screen broken in 4" issue if started in a cold place, but would work fine on the second try. This happened 3 or 4 times, since then i keep it powered on if it's cold, and i've never had it since. Also my 8400GS is overclocked to the max and i game on it anytime i'm away from my desktop computer, and it's working perfectly.
