    OP= original poster.
    Overclock at your own peril.

    Interesting. P5 doesn't work for me. It just sets the core clock at 405.

    ----------

    As stated in the original post, the downclocking is a feature of the 600 series. You are supposed to increase the voltage in order to circumvent this, but I haven't been able to figure out how to change the voltage to the 650M yet. The Nvidia Inspector method for voltage isn't working for me.

    You can't adjust voltage on Kepler(600). Nvidia has disallowed it via software. Only cards like the MSI Lightning and PE have software voltage adjustment and those are desktop cards that are non-ref.

    Kepler automatically boosts up the clock speed when the GPU usage is high enough as long as it's still within the TDP limit. That's what the percentage in MSI Afterburner is, the percent of overclock boost.

    @1035/1729

    Assasins Creed - Revelations runs at 2880x1800 @ ~25-33fps. Very playable and looks beautiful! Also, GPU temps never exceeded 71c.

    I cant seem to get it to boost higher than 1035. I followed the link the OP posted, but I can't seem to get it to exceed +135...even if I use command line and type a different offset.

    sadly, for some reason, this is doing nothing.

    Too bad none of this overclocking business benefits any software on the Mac side, which is why most people buy Macs. While you may be overclocking your graphics chip to the same speed as the stock rMBP, you cannot do this when running Mac OS. Running Mac OS on the cMBP will have slower GPU clock speeds than stock Retina. There is no way to change this.

    I am sorry to hijack this thread once again, but at this day i still could not find a super noob guide on how to OC the GT650m on a retina macbook pro.

    i want to do it so badly but i can't figure out how to..

    i tried msi afterburner, nvidia inspector etc. and none of them seems to give me the Mhz frequencies like i used to have on a macbook pro with gt330m

    So please please please, somebody write a guide for G. sake :):D

    how to stop the gpu from underclocking?

    Thanks to asdad123's post I have been able to OC my non-retina MBP 650m GPU. HOWEVER, when I overclock the GPU using this method, my GPU underclocks itself when I try to do benchmarks and play games to its original 675 MHz speeds instead of the newer 900 MHz. But When I stop these GPU intensive apps, it goes right back up to 900 MHz. I understand the nature of the newer 600 series chipsets doing this, but it looks like in asdad123's screenshot he has his overclocks locked with no downclocking during intense apps. What is the coding you used asdad123? Any help would be greatly appreciated. here's my .bat file I have for my overclocks now in Nvidia Inspector:

    nvidiaInspector.exe -setGpuClock:0,2,900 -setMemoryClock:0,2,2508 -forcepstate:0,2

    edit: also to note I have toggled between forcepstate :0,2 and 0,1 and I get the exact same results. thanks!

    ok, so I have no idea how the OP is accomplishing this, but here is how I got mine to get up to the same speed the OP is accomplishing.

    Seems like I am getting better framerates and more consistantly low temps setting it like this:

    nvidiaInspector.exe -forcepstate:0,5 -setGpuClock:0,1,1200 -setMemoryClock:0,1,1659

    unlike the prescribed settings this setting does not downclock when temps get too high...and they temps seem to stay low.

    Can you please make a small how to guide on how you do that ? since i requested many times on this site and nobody answered me... i am asking you if you can do it please...

    Much appreciated in advance.

    My temps stay pretty low when I run this (about 60-70C), but my screen goes black about 5 seconds later... :(

    That's weird, I haven't had that issue. I've been getting much lower temps running like this too. I did have a couple games go slower tho. Depends on the game.

    Your comment would be valid, if the GT 650m were Fermi.

    his comment aint even valid on any kind of fermi or kepler. tell that to the people that oc the 580m to the 560 ti levels, including voltage bump

    I think it's a power issue. If I use ThrottleStop to lower the power consumption of the CPU, it seems to be stable (until I run a graphically intensive app...). Would you happen to be using the 2.6 or 2.7 Ghz processor like the OP? I'm running the base 2.3 Ghz processor.

    ----------

    The guide is in the link from the first post...

    2.6, do you have a safe download link to this software?

    I think that must be it then. Then 2.6Ghz processor must use less power, which allows for greater overclocking of the GPU. I wonder how the 2.7Ghz processor stacks up. It's be awesome if someone with the 2.7Ghz model could chime in.

    I think this is the official download:

    Hi All,

    I have a 2.7 rMBP with 16Gb of RAM, more than willing to try an OC tonight; however, I really don't know what I'm doing.

    Now I know nobody owes me an "idiot's guide" to overclocking, and I've been scouring the internet over the last few days looking for guides (and I think I have a general idea about what I'm doing now). But if anyone wants to tell me "this is what I would do, from square one" that would be awesome.

    Right now I'm wondering, it seems like the GPU temp is the main issue since the cores are fast enough to run intense 3d, but why are the core temps jumping to 104-105C (as OP mentioned) and wouldn't that trigger down-clocking regardless of GPU temperature? I have heard 105C is the point where you can start to do damage to your machine and don't really want to go that high. Also, if I just use MSI afterburner (and maybe the NVidia inspector to change my p-state to 0,1 or 0,5) is that all I need to do? Or is there some other important stuff I should take care of like trying to "unpark" my CPU and stuff?

    Thanks! I'll be checking this thread through the day and once I get some sound advice I can start tinkering around.

    I don't think you should see temps as high as 104-105C, at least I didn't notice anything that high on mine. My GPU didn't even go higher than 80C with the fans running. So I wouldn't really worry about it, just watch your temps when you are overclocking (nVidia Inspector displays the GPU temp, ThrottleStop will display CPU temps; I use OCCT which displays all the temps). I pretty much just used the guide in the first post, so I would just follow that and post any questions you have here.

    Ok it took me a couple of days worth of testing and researching to get these results with my cMBP non retina (check my sig).

    Maximum stable overclock from 775Mhz/2000Mhz to 1150Mhz/2350Mhz. These clocks are 100% stable, not just benchmark stable... stable stable.

    Temps never exceed 86 deg C (up from about 82 deg stock) and it doesnt downclock at all. I lapped my heatsink (wet sand 400grit>600grit>1000grit>3000grit>notebook paper> microfiber cloth...I could see myself in it) , changed to AS Ceramique 2, and fiddled with the Luddo's fan control but the fans still scale, they arent at 100% all the time ;)

    To double check this I ran intel burn test (very high) and furmark at 1680x1050 8x MSAA concurrently for 4 hours straight with the Nvidia inspector log/graph going... didn't once downclock although it did downvolt a few times from .95 to .90 (I wish we had voltage control on these things) and no artifacting (at least that I saw). Immediately after the 4 hour burn test I ran 3dmark 11 back to back 3 times, the final score was 3153, thats up from 2251 at stock or a 28.7% increase. This is in the upper range of GTX 670m's and well beyond a GTX 660m.

    Well I am impressed :D

    I am convinced that with a few more modifications this thing could best a GTX 675m, having voltage control is a start. Cooling is the next thing, I got the best thermal compound I could find locally but there is better stuff out there, you could also use thermal adhesive and attach some low profile ram sinks to the vram (might be tricky to fit). You could take the bottom plate to a machine shop and have them mill some slots in right below the fan intakes... those things would drastically improve cooling, that combined with voltage control (or at least the ability to disable downvolting) would make this an overclocker's wet dream.

    now to go do some serious gaming!!

    Any idea on how to oc the 2011's with the ATI graphics? More specifically what software would I need. Yes i have bootcamp.
