Qosmio X770 - GPU/CPU temperatures

Question

Hello everyone,
What temperatures do you guys have for the CPU and GPU?
Usually mine are around
45-50 deg for CPU and GPU - normal conditions
85 deg for CPU and 78 for GPU - during games 1920x1080 resolution full details
Regards,

Answer 1

I've got the throttling problem, which means when the GPU get's under load
GPU-clockspeed is reduced form 775 to 203 MHz and games aren't playable anymore.
It happens in nearly every game or benchmark after 1-4 minutes.
The temoerature goes to 67 degrees before downclocking, but some people are reporting
reachable temperatures of 78 degree (without throttling). The main problem is that
3D Vision is nearly unusable, because it pushes the GPU-Load to high to run without
thottling.
These are the things I've tried so far:
1. downclocking gpu-frequency to 675MHz and 725MHz with EVGA precision:
- works for unigine heaven benchmark (1280 x 720, 3D Vision off)
- throttling in unigine heaven with 3D Vision enabled (clocks down to 202,5 MHz)
- throttling with Burnout Paradise and enabled 3D Vision (clocks down before showing the
first 3D picture)
2. disable speed-stepping (and turbo boost) for CPU in BIOS (ver 1.30 by the way), to
preserve the power for the GPU, no downclocking of GPU
- throttling in unigine heaven benchmark (1280 x 720, 3D Vision off)
- throttling in unigine heaven with 3D Vision enabled (clocks down to 202,5 MHz)
- throttling with Burnout Paradise and enabled 3D Vision (clocks down before showing the
first 3D picture)
3. tried to disable GPU throttling via NVPMManager (Disable Overheat Slowdon Override)
- no effect
4. tried to disable GPU throttling via GPU-Z (/GTC500OCP commandline-option)
- no effect
5. tried step 1 - 4 with several newer drivers (laptopvideo2go)
- same result as described und 1-4
- additional problems, no working 3D vision for example
--> returned to stock drivers (which don't support youtube with 3D Vision)
6. email to toshiba, yesterday
- no answer
I think this is a patchable problem (bios for GTX 560m), because for the desktop GTX 560, one can
find several articles about contributor-dependent enabling of the power limiter. hardwareluxx
has no problems while benchmarking the notebook (31+ fps in unigine heaven, which aren't
reachable with underclocking), so maybe it worked with another graphics-BIOS. I'll wait a few days
for a mail from TOSHIBA support, before returning the notebook. The machine would be really nice, if
it would be working as expected.
Best alternative for the X770 with 3D is the ASUS G74SX - you can't find anything about throttling in the
web for this one.
