D830 ML Window lags

[piterakos]

using fakesmc ver5.1.59 and running ML 10.8.3.

Other kexts are:

 

ACPISensors

AppleACPIPlatform

AppleACPIPS2Nub

AppleHDA

ApplePS2Controller

BCM6722D

CPUSensors

FakeSMC

FakeSTAC9205

IO80211Family

IOATAFamily

IOAudioFamily

Ispcidrv

OSvKernDSPLib

Patched_10.7_AppleRTC

Voodoobattery

VoodooTSCSync

 

All of them are installed by EDP.

You should no longer need those xxxSensors kexts in /E/E. If you lookup within the PlugIns folder of the FakeSMC kext, I'd expect you to see 4 sensor kexts in there. This could be the cause of your issue.

[piterakos]

you are right they are included in fakeSMC so i removed them but hwmonitor still doesn't show gpu

[Hervé]

You are using the HWMonitor version that was very specifically indicated in the article, aren't you?

[piterakos]

for anyone that is interested the FakeSMC+MBP5,1 SMBios method works with impressive results.

Native speedstep + instant gpu throttling.

Also setting the resolution at 1600x1000 window lag is minimised

 

Well done to the restless people who showed the way!!!

im glad to hear it worked out for you.

Just to complement this, today I got access to my friend's D830 nVidia (135M) again so I implemented this fine-tuning. The laptop runs ML 10.8.3 on a 2.2GHz T7500 and WXGA 1280x800 LCD, still I used the MBP5,1 settings and all works just fine afterwards: native SpeedStep + GPU clocking.

The only differences I see compared to the D630 are the reported GPU core/memory frequencies: 168/100MHz, 275/199MHz and 400/399MHz, where I was seeing higher memory clockings on the D630. Can't see any obvious performance impact though, everything remains very smooth.

 

The reported T° appear excellent too: CPU idles around 45-48°C and GPU around 54-55°C at 168/100MHz. I noticed a Tjmax at 90 in the system log so I manually edited the CPUSensors kext's plist to set Tjmax to 100 (previously, this sort of things was done in IntelCPUMonitor kext), otherwise reported CPU T° are a good 10° lower.

 

XBench 32bit gave me a result of 3063 on 1st run (D830 has 2Go DDR2-667 and 120Go 5400rpm HDD).

 

NB:

• MB5,1 and/or MBP5,1 SMC ids and SMBIOS profiles can both be used. I did not see any obvious difference between the 2 during my tests (though they were not extensive), although GPU throttling might be a bit quicker with MBP5,1 than MB5,1.
• MB4,1 settings break native SpeedStep and limit GPU to 275MHz, so that cannot be used.
• Regardless of the selected SMC id & SMBIOS profile, IDA BIOS mode is not supported with that T7500 CPU: if enabled, FSB speed gets reduced from 200 to 182MHz. That differs from the T9300 with which IDA can be enabled without impact.

digging up an old post here but i didn't know where to ask.

 

I recently played with an imac7,1 smbios on a desktop pc which included the following lines:

<key>SMexternalclock</key>
        <string>200</string>
        <key>SMmaximalclock</key>
        <string>2200</string>

My cpu is a pentium E2160 @ 1.8GHz but after using that smbios hwmonitor shows throttling up to 2,2 ghz. Is it true or is it "fake"?

Can someone oc just by messing with smbios???

Off-topic. Note that this is just cosmetic. You could put 10GHz if you wanted to!
