Retina MBP BootCamp Overclocking Results

Mr MM said:
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 meant Kepler. A few non-ref cards lets you. EVGA's requires an external hardware device and so does ASUS DC2. MSI Lightning can do software voltage modifying so far.

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!!

Mind sharing how you managed to change the clock speeds? If I open nvidia inspector on my classic 2012 I can only declock Level 0 and 1 but Level 2, is greyed out and no accessible :/ sooo ? please? :D
 
I always find these posts interesting, but I was hoping for some native OSX tests. Guild Wars 2 and Witcher 2 in particular.
 
Anyone still here?

I've pushed my GPU to 1150/2350, however whenever I run benchmarks, the core clock drops down to 786. Why is this?

"The only difference, was that to get into P2, I had to type in nvidiaInspector.exe -forcepstate:0,1 instead of 0,2."

I have a feeling this is your answer. Change it to 0,1
 
After trying several settings and drivers on my rMBP i'm getting GPU throttle, from the default 900 to 725, even though the max GPU temp i'm getting is 72... I tried p1 and p5, tried throttlestop, resetting PRAM and SMC, but everytime, after 15 min of skyrim the throttling starts... any ideas?

Edit: Well, looks like going back to apple's bootcamp drivers solved the problem. It's not ideal, but i guess it'll have to do for now...

Hey guys,

I was trying to OC my MBPr 2.3GHz with Afterburner and what I don't understand is:

Clock Rate +135MHz (result 1035MHz)
Mem Speed +900 (shows me a result of 3300 in After Burner, which sounds to crazy high?! Why is this? Shouldn't it be default clock + 900? When setting higher than ~920 I get artefacts in FarCry3...)

Actually I would be ok with a extra clock rate of 135 MHz and there comes my next question:

Do I have to worry when running this slightly overclocked system? I use Lubbos Fan Control in order to have the fans turn at proper speed.

Your answer is much appreciated!

Regards, MaKin211

I had no artifacts from increasing the core clock and only received artifacts when going to 1000 on the memory increase. 950 was perfectly fine and no artifacts. Im sure if I figure out how to pass the software limitation of MSI afterburner, the GPU can handle higher than the 135 increase for the core clock.

My final stable overclock was 1035/1729, up from the original of 900/1254. One would think temps would go up alot with this type of overclock, but mine only went up by 1C to a max of 78C for the GPU.

With this overclock, I was able to achieve a 3dmark11 score of 2860. This is nearly a 27% increase over the previous score and higher than a stock GTX660m. I couldnt believe how far this card can be pushed.

Can you explain that to me? You add 950Mhz Mem Clock on Afterburner, but the result is not 1254+950Mhz, but 1729Mhz which is 475Mhz, the half of 950Mhz. When adding 135Mhz to the gpu clock though, it results in 1035 MHz. I don't get this. :( Don't know in what ratio to overclock with 1035Mhz on GPU in order to not unnecessarily stress the MacBook.

Thanks in advance!
 
Can anyone comment about their results in reapplying thermal paste on the rMBP? I'd be curious to hear some before and after figures for CPU and GPU.
 
Hy guys!

I need a little help.

A tired to overclock my rMBP but every time I set the inspector, to a higher (or different configuration than the stock) setup, it doesn't change the gpu core speed. The memory changes but then goes back to stock.

Do you guys have any idea?

Not sure. I overclock mine temporarily to play a game. Even with higher settings I do not see performance increase. Meh. Maybe the changing back to stock is a failsafe if the card is getting to hot or configuration is not optiomal...or something.

Where do you type this in at? In the shortcut? Like is there a tutorial on how to do this. I used the site referenced earleir, but it still doesn't tell you where that command goes.
 
@Asdad123

Can somebody help a noob out in this problem :) ?i am trying to over clock the 650m on my rMPR 2.6 8gb but the core clock seems to be stuck at 900 even when i give values like 1200 but the memory clock goes upto 2000 perfectly and then gets stuck but thats ok,i wonder whats the problem with the core clock,can some body please help me??i used the force state 5 and the others too only with forcestate 5 iam able to increase my memoryclock with the others iam not able to do anything. :)

I dont know it should be by def 2508.. but at first it was around 758 some times jumping to 1200. so now what should i do? wait for a new driver or is there some workaround??? :confused:
 
you guys have some balls, i'd love to do this to mine but i'd think i'd cap myself if i broke it :(.

hoping for a 760m....
 
anyone done this on the 750m in the haswell yet?

I've put afterburner on (with 331.65 nividia drivers) and to be honest it doesn't seem to do anything....
