Hi,

I have bought a new Gigabyte Nvidia Gt 640 OC.

But my problem is that the graphic performance isn't great.

I tried several things:

1. Change the smbios (switching to another model): MacPro3,1 ; MacPro4,1 ; MacPro5,1

2. Patching the AGPM
3. deleting AppleUpstreamUserClient.kext
4. Installing the new Nvidia drivers

The system is lagging when I maximize or minimize windows. Games (CS-GO) are running perfect.

I've got a Core2Quad Q9400 on an Asus P5Q Pro with 8 GB RAM and a Samsung 830 128 GB SSD for the os.

Thanks a lot
Greetings BanneJim

Hi,

do you have cpu spikes when the lag occurs? (see activity monitor)

Hi,

the CPU use doesn't go above 12% .

Do you think it is a problem with Speedstep?

@iFIRE

Because the iMac10,1 has a Core2Duo in it?

Try deleting AppleGraphicsPowerManagement.kext and test it again.

@Taruga

Sorry, but I don't think that doesn't make sense because when I use the MacPro 3,1 smbios.plist the AGPM isn't used.

Check your GPU core speed, it must be running at half speed of so....

If that´s the case, then maybe only modding the AGPM can fix it

Mh,

I already modded my AGPM with this:

<key>Vendor10deDevice0fc1</key>


<dict>
<key>BoostPState</key>
<array>
<integer>6</integer>
<integer>13</integer>
<integer>13</integer>
<integer>6</integer>
</array>
<key>BoostTime</key>
<array>
<integer>1</integer>
<integer>1</integer>
<integer>1</integer>
<integer>1</integer>
</array>
<key>Heuristic</key>
<dict>
<key>EnableEnergyPstate</key>
<integer>1</integer>
<key>EnergyPstate</key>
<integer>5</integer>
<key>ID</key>
<integer>4</integer>
</dict>
<key>control-id</key>
<integer>17</integer>

</dict>


This lines are for a Mac Book which uses a GT 650 M which is similar to my GT 640

You should use iStat Menus or something like that to show you GPU Core Speed and check if it shows the same speed with games and on the desktop.
I think your GPU when in desktop mode, is working with a lower gpu clock.

I don't know much about AGPM plist settings but maybe your should try something like this:

<integer>13</integer>


<integer>13</integer>


<integer>13</integer>


<integer>13</integer>



Just to check if GPU speed increases in desktop mode or not.



I never bothered much with AGPM, I'm using a GTX 560 Ti and I noticed that my GPU works at half speed on desktop mode but sometimes with some load, it changes to full speed

Is your screen flickering really bad when it happens?
