Kynyosu Posted June 16, 2013 Share Posted June 16, 2013 Hello everyone! I've found out that 10.9 somehow reads the device differently from the same DSDT file. So I basically need to modify my DSDT (adding name,ioname,compatibility injection) but i don't have much experience in dsdt editing. With a little help from old napalm it says i need to inject this:  Method (_DSM, 4, NotSerialized) { Store (Package (0x08) { "device-id", Buffer (0x04) { 0x18, 0x3A, 0x00, 0x00 }, "compatible", Buffer (0x0D) { "pci8086,3a18" }, "IOName", Buffer (0x0D) { "pci8086,3a18" }, "name", Buffer (0x0D) { "pci8086,3a18" } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) }  Thats explanation of temp behavior: my GPU GTX 650 has almost same temp like GPU and this isn't normally because it's a Kelper GPU so in Windows around 28 30C maximum. In 10.9... 37GPU 1500 rpm 33 CPU 1507 rpm This is my DSDT: http://cl.ly/373m2e3w0N0D Now who can help me to inject new IOName code... The idea it's to regain same temps/rps fans as it in Mountaion Lion. Actually Mavericks reads a little different the values so it needs to be corrected! Thank you very much, help appreciated!
