GTX 460M still throttling (arrrrgh!)

still pondering why it does this for you. I can run both prime95 and furmark simultaneously and get no throttleing, so I'm thinking that between the 460m and your processor that your maybe exceeding the maximum wattage of your PSU? I Wonder if there is some way to monitor both voltages and see if its the case. Sounds like it could also be an obscure bios issue too(similar to the 580m power throttle). No way to really confirm it that i know of.

It's been well established that the 150W max of the m15x is easily exceeded running CPU+GPU at max. In my opinion this is just a design flaw in this laptop.

I never have problems with throttling with mine during gaming. Furmark just shuts my computer down.

I am having the same problem, though in games too. Geforce 460m, 820QM CPU, and Skyrim and SWTOR throttles every few minutes unless I enact a 40fps frame limiter (effectively reducing the GPU usage).

100% GPU usage and 66% CPU usage results in a flicker of the screen followed by a drop to min clocks on the GPU. I am using the A09 bios, and latest VBios for the graphics card.

Thankfully, the frame limiter prevents almost all stuttering, and still gives me nice and smooth gameplay. Keeps the laptop a bit cooler too. Still an annoying work around :/

Not sure why some of us have this throttling and some of us do not. I wonder if they up-rev'd the power management system in the laptops at some point.

you could call dell and see if they have a way to fix it, but Its prob somthing in the bios so you don't fry your machine.

yup, but it still does not answer the question as to why his machine does this and mine, which is almost identical (740QM vs 820QM, same GPU), does not throttle in any games I have tried so far...

there is something nefarious here

hmmm are you both running the same sets of bios, Vbios, and graphics card drivers?

it seems so
