    Default AW M15x Throttling Issue Investigation - Stock clocks and overclocked.

    Info no longer relevant. Dell has released a new bios update that resolves it.

    you can run OCCT to have it print out in a big chart and the temps will fluctuate along with the speed...theoretically

    is this a big issue, man just ordered M15x and now I hear this. hopefully not a mainboard issue.

    Until others confirm this is happening to their systems, it's not definitive. Unfortunately not a single person has stepped up yet.

    I will test mine..when it arrives! :complains: Which CPU do you have again?

    I'll also post some tests using my Kill A Watt power measuring tool. It would give us a better idea of how loaded the AC Adapter really is.

    Agreed, run the OCCT PSU test and graph it... see what you get.

    I ran OCCT PSU but it only shows temperature changes, not frequency throttling. I did however run GPU-Z at the same time and this is what it looked like:




    The spikes are when it hit full stock clocks and the rest was the throttled 3D clocks.

    is the M15x power brick 120W (19V/6.3A)? if it's like the G51J, then AW cut corners on power. the graphics chip requires 75, CPU @ 55, and extra for peripherals (screen etc.) which go well over the 120W with my G51.

    log CPU freq/multi with http://www.cpuid.com/tmonitor.php while having those running. my guess is it will be throttled when the GPU is used and vice versa.

    No, the M15x uses a 150W PSU.

    It probably requires closer to 180W.

    Hey thalinx, the PSU is rated at 150W. I believe the old area m15x used the 120W adapter. I'm going to do a respawn (factory restore) to rule out any possible software glitch and then run the Tmonitor with the benchmark programs. I'll update this thread once I do.
