E6510: NVS 3100M throttling

[Hervé]

I'm quite confident you can achieve good results with the right settings. Reason for this is that both the NVS 3100M of the E6410 and the GT 330M of MBP6,1/6,2 are based on same architecture GT2xx.

Info.plist of AGPM kext shows the following nVidia ids for MBP6,1/6,2:

Vendor 10de, Device 0029 -> GeForce GT 330M = chip GT216

Vendor 10de, Device 0a34 -> GeForce GT 240M = chip GT216

 

As far the Dell Latitude E6510 dGPU:

Vendor 10de, Device 0a6c -> NVS 3100M = chip GT218

 

So, they are close cousins.

 

Inject the section for Vendor10deDevice0029 of MacBookPro6,1 or 6,2 entries to your FakeSMC and adjust the thresholds to test:

<key>Threshold_High</key><array>
<integer>57</integer>
<integer>70</integer>
<integer>80</integer>
<integer>100</integer>
</array>
<key>Threshold_High_v</key>
<array>
<integer>1</integer>
<integer>3</integer>
<integer>98</integer>
<integer>100</integer>
</array>
<key>Threshold_Low</key>
<array>
<integer>0</integer>
<integer>68</integer>
<integer>75</integer>
<integer>94</integer>
</array>
<key>Threshold_Low_v</key>
<array>
<integer>0</integer>
<integer>2</integer>
<integer>4</integer>
<integer>99</integer>
</array>

So after a bunch of experimentation, I can see the gpu changing stats when expected, at least from the log.  from the HWMonitor side, I still see it sitting at 405Mhz, and a voltage of 1.00V. Im beginning to wonder if either:

1) HWMontior is just reporting wrong. If so, is there another way to check the voltage/clockspeed of the GPU besides FakeSMC plugins?

2) the voltage being at 1.00V is restricting the chip from going to the top clock speed somehow.  

 

I will keep testing, but would welcome any insight anyone can provide.

 

Edit:  Should also be noted that I do see the GPU occasionally drop the the lowest state (202Mhz) every so often, and typically only for a second.  This seems to indicate that I am capable of changing clock speeds on the GPU, but just not reaching the top speed.

Unlike the GPU state changes log entries, HWMonitor is not "real time": the counters/stats get refreshed at a pre-defined interval, typically anything from 2 to 5s. You may reduce this to 1s and see more GPU state changes but it'll never be as time-accurate as the log and, clearly, still some work to do on the thresholds. Cuda-Z may be more appropriate if it still works...

 

 

Keep on trying, you're on the right path.

 

Voltage will vary according to GPU load and throttling; it's not a fixed parameter and not something you can adjust. In that respect, it's like the CPU voltage re: CPU SpeedStep.
