    I think I read somewhere that the monitoring programs (afterburner, gpu-z, etc.) might keep the frequency high, but I'm not sure. If this is true I guess there wouldn't really be a way to know if it's downclocking properly right now.

    even when the nvidia gpu activity icon in the tray tells me the 650m is off gpuz tells me its at 745mhz but if it was off would gpuz still see it . i wonder if the card is not fully powering down

    I "think" the problem was that I may have installed the Nvidia driver right after installing the Intel one, instead of rebooting first. After installing the newest Intel HD4000 driver, rebooting, then installing Nvidia's newest 306.02 beta driver, everything seems to be working fine. Needless to say, I ran driver fusion in safe mode as well.

    My gpu activity icon is now black in 2d mode, whereas before it was always the rainbow color. Also, HWMonitor no longer shows the 650m status when I open it unless something is using the 650m. The only thing that sucks is that I can only run GPUZ and MSI afterburner when I want to be in 3d mode, because they enable the 650m. I can't auto start MSI AB because of this, so I'll have to only launch it when I play games. That totally makes sense in a way, but I could run either of those programs without turning on the 6750m in my last laptop.


    Yes. They will run the 650m at 0%, but core/memory will be 745/1000. The problem is that it still makes the laptop heat up. I typically have MSI AB setup to auto run, but I'll have to stick with manually opening from now on. The other thing I'm a little sad about, is the fact that you can't control the fan. I was hoping I could crank them up to 100% while gaming, but there doesn't seem to be any way to do this. I've tried MSI AB, Evga Precision, and Speedfan, none of which give you any kind of fan control. Perhaps this is Optimus related.

    Well before I fixed everything, my keyboard was warm and my cpu temps were in the 60s. Now that it's fixed, the keyboard is cool and temps are in the 40s. Problem with GPUZ is that it enables the 650m upon opening it (same with MSI AB). Anyway, I'm almost 100% sure the 650m is either off or running at 145Mhz, though I have not yet concluded on which. Lastly, if you want to be 100% sure the 650m is off, all you have to do is disable it in device manager and voila.


    Edit: As I already mentioned above, HWMonitor will not show the 650m when it's started with nothing 3d running. Well after opening CPUZ and seeing only the HD4000 under the graphics tab, I'm now 100% convinced that the 650m is off and not running.

    I am using the latest intel driver and nvidia driver not the ones from samsung's website. I just have a gpu widget and this is what it shows. Left is just with web browser open, right is with gw2 running about medium settings.

    Thanks for this and I'm also running the same drivers as you. Btw, in the left photo, something is running 3d (my guess is some kind of monitor with 0% usage and 745/1000 core/mem) and that is why your cpu temps are in the 60s. Mine currently shows 0Mhz for core/memory and well everything. If you're running msi AB, gpuz, speedfan, anything else that uses the 650m, or do not have Optimus setup right, it's going to put your cpu temps into the 60s while doing light stuff. If you disable all of that stuff, your gpu meter will show all 0s like mine and it will turn off the 650m, thus giving you cpu temps around 42-47C.


    Edit: PCMeter, which is required to run the above, does indeed turn on the 650m. It's not being used, but it is being turned on from that. If you don't mind idling in the 60s, then feel free to use it, but if you disabled/unistalled it, the 650m would be off and your idle CPU temps would in the low to mid 40s.




    Instructions to confirm 650m is turned off (Thanks partly to gadgetrants)

    Go into the Nvidia control panel and check Display GPU activity Icon in Notification Area

    When the 650m is totally off, the tray icon will be black like this -

    When the 650m is on even when it's running at 0%, it will still produce heat and you can tell by the icon changing to the following rainbow icon.

    I bought this laptop today and I love it except 1 thing... Heat everywhere I feel everything getting warm even around the keyboard sometimes while gaming gw2... Gpu reaches 85C cpu 90-93c I went to compusa and replaced it and got a 2nd one and it is exactly the same.. Am I missing something or are these the normal temps of this machine.. other than that I love this.. disabled hyper threading trying for better temps but meh same My temps while browsing and watching videos varies from 47c to 72c :(

    First, do what I listed above and the laptop will be 100% cool while doing light stuff. If I had to guess, you're 650m is probably running at 0%, but still turned on and therefore dding heat. You need to make sure the icon (shown above) is black or something is turning on your 650m. Programs that only do things like monitor (MSI AB, Speedfan, GPUZ, etc), will force your 650m to turn on.

    For GW2, even with the temps you listed (mine are similar), I personally don't think the laptop gets that hot externally compared to others I've used. If you want to get them even lower, disable turbo boost by going into power management and change cpu maximum to 99%. From what I've read, this should drop the CPU temps 5-10C and have little impact on frames.

    The icon is black and says there is no gpu activity

    so.. I shouldn't be concerned of 90's Celsius on the cpu then? i've seen it up to 95c while gaming I use HW monitor for it

    Thanks for that. The graph was flashing between grey and color with PCMeter and solid grey with it turned off.

    edit: The GPU meter does need PCMeter to run. AllCPU still works without PCMeter. It just won't show temps.

    I have another issue I've been trying to figure out. Every time I turn on the computer from being inactive (cold) for 8+ hours. It does the same thing whether it's turning on from sleep, resuming from hibernation or from a fresh boot. The computer freezes and the screen goes all crazy and has green blocks. This only happens when the computer has been sitting for awhile.

    I will get a picturet next time it happens. Holding down the power button and rebooting fixes the problem.

    Well going up to 72C even with video seems higher than what I'm experiencing. What's your ambient temp? Mine is 75C.

    Edit: I think you're fine in the 90s (TJMax 105C), but I'd still set your CPU max to 99% in power options. It'll disable turbo, your laptop will run cooler, and it shouldn't have too much of an impact on your frames.

    The only time I've experienced anything like that, was immediately after uninstalling intel/nvidia drivers (prior to rebooting for a restart to run driver fusion in a safe mode). It only happened once, was different than what you're explaining, and it didn't seem overly abnormal to me due to the vga drivers just being uninstalled. As for your issue, I have had nothing like that happen to me. Does it eventually settle and go back to normal and if not, what do you do to resolve the issue? Reboot?
