happens to me the same in GTA ELFC and Deus Ex
did not try using external monitor - but why in the hell I bought this bloody portable computer to transport also an external monitor? =))

65 degrees, i dont get it why they would cap it so low, plus they didnt even program the fan right because its never running in 100% rpm even in full stress, next time im going for alienware

What progam do you use to clock the GPU?

I just downloaded MSI afterburner... I will try this one too!
Thanx. Hope underclocking will do some good!

I've got the same problem with X770-107.

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 manual 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, 2 days ago

• no answer so far

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 G74SX - you can't find anything about throttling in the
web for this one.

I found a way to disable throttling!! Look at this:
***Bios change history, version 1.20
"Added code to notify NVIDIA VGA to change P-State when EC issued VGA protection function."
I thought that if I downgrade my laptop bios to an older version I remove this effect. One problem: If you have bios version 1.30 you cant downgrade bios from the system level. You should unpack bios downloaded from http://cdgenp01.csd.toshiba.com/content/support/downloads/sby5v110.exe (official link) and burn bootable disc (image is in bios folder). Then you must reset system and set dvd/br-driver in boot options as 1st. Next appears the command line and you must write "bios". Press enter and... You have to wait until the bios to install and the system will reset.
DONE

Throttling excluded!! Of course working bios version is 1.10, because in version 1.2 introduced nuisance "VGA protection function"..

Very sorry for my english I hope I helped someone

Yes, indeed that solved the problem:

30.1 fps in unigine heaven (1280x720, Anisotropy 4x) with no throttlng
15123 points in 3DMark 06 with no throttling

3DVision not tested so far

fan doesn't go to full speed as before
maximum GPU-temperature reached: 70 degree

In my opinion you solved the problem which didn't exist before Toshiba's BIOS patches,
hopefully they'll fix it with the next BIOS-release

thanks MaciekPL

but how did you find the old bios, i've been searching for it for 3 days now and only found 1.30
