what/who's OP?
and so... think it's good to OC or just to test the limits?
OP= original poster.
Overclock at your own peril.

Is there a difference between the P1 and P5 power states? I can lock my GPU in the P5 state through the .bat method and it seems like it overclocks as well as the P1. My stable overclock seems to be around 1070 Mhz / 2900 Mhz memory. After it goes above 80c, it does seems like the computer throttles itself every few minutes.
Going strong.. 83c temps at 1000/2800.. Seems hotter than the OP's temps.. I guess the Retina does have some kind of crazy cooling system!
I'm hoping to prove that the cMBP has a higher graphics overclocking ceiling.
Edit: 1100mhz core stable.. I froze up trying 1150mhz. Incrementing slowly past 1100 to see what the ceiling is.
Seems like the GPU starts to throttle back to 675mhz for 1 second then back to 1100.. does this every 5 seconds or so.. I'm thinking it must be the GPU temps causing this.
Video memory is stable at about 1700mhz.. Can't get much past this before artifacts start to show up.
Just use MSI Afterburner and enable unofficial overclocking:
edit MSIAfterburner.cfg from the installation directory

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.

My temps stay pretty low when I run this (about 60-70C), but my screen goes black about 5 seconds later...![]()
You can't adjust voltage on Fermi(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.
Fermi 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.
Your comment would be valid, if the GT 650m were Fermi.
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.
nobody cant say HOW TO OC ?

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?
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 think this will get you started https://forums.macrumors.com/threads/1142028/Any idea on how to oc the 2011's with the ATI graphics? More specifically what software would I need. Yes i have bootcamp.
