Overclocking trouble with the rMBP and the newest NVidia drivers (314.07 and 314.14)

[imperialnavy]

Hello,
for a while i have been experiencing strange issues with my overclocking in combination with the last 2 drivers, the 313 series as well as the newer 314.07.
With the 310.90 i was able to achieve 1150MHz for the core and about 3100 for the memory. With 313 and 314 i can still reach a memory clock that high, but it is no longer possible for me to go above 900MHz on the core. Did they maybe change the p states? Or does NVInspector need to get updated?


This is what i have in my bat in order to activate the overclock (works on 310.90 without a hunch , but on 313/314 it only reaches 900) :

nvidiaInspector.exe -setBaseClockOffset:0,0,250 -setMemoryClockOffset:0,0,550 -setpowertarget:0,0 -setVoltageOffset:0,0,0 -setGpuClock:0,2,1150 -setMemoryClock:0,2,3058 -forcepstate:0,1

This is for restoring it back to normal :

nvidiaInspector.exe -forcepstate:0,16

I hope someone can help me out here!

Anyone?

Have you tried MSIAfterBurner? Seems to be over clocking just fine for me.

How far can you overclock with afterburner? 1035MHz is the limit? NVInspector can usually go higher.. (Or did all that change by now due to some update? )

 

[imperialnavy]

I just tried the newest Nvidia Beta driver, 314.14 and my problem still persists.
Both NVInspector 1.9.7.0 and MSI Afterburner 3.0.0 Beta 6 can not go past 1035 MHz on the core clock. The only driver that still supports that is 310.90.

Is no one else experiencing this??
It kind of sucks not to be able to use the newest drivers, considering that they bring some nice improvements with them...

According to nVidia, past the 310 drivers, they changed the way the drivers reported frequencies, so maybe that's why you can't push higher.

 

[imperialnavy]

So is it a bug in a way? I take it, there wont be any solution for this one?

 

[bill-p]

Nope. Supposedly, people moaned about the frequency representation as well. Even at stock, it was clear that they were different from the 310 drivers.

And nVidia won't do anything.

While i didnt test it yet, i somewhat doubt actually, that performance increases of up to 23% can replace an overclock from 900 to 1150 MHz...

So the basic rule now is, if people want to have high performance rMBPs, they need to stick to 310.90 or below?

That and that damned unsolved SMC bug are real performance and fun killers

hi dude ,, exact same issue here with my Nvidia GT650M in MSI GE60 gaming laptop

with 310 driver I was able to achieve any core speed I want ,,, but with the 314 one I coul only achieve 969 ( +135) only ,, in addition ,, msi after burner could not afford that +135 for me ,, only with NVidia inspector could do that ,, and as you mentioned the memory clock still free to adjust just like before ,,,
some thing I would like to add ,, I could notice a difference In performance between
1_ Nvidia drive 310 with o.c gpu (999MHz)
2_Nvidia driver 314 with o.c gpu ( 969MHz)

the better one was the seconed ,, I don't really know why ,, but that what I felt

however ,, I think the wil probably do some update either in the o.c ing programs or the NVidia drivers , and with that update we will be able to do free o.c ing with the latest drivers
