@kgp what was the template you used to start building SSDT-X299-iMacPro.aml ? Did you extract it from your system?

As I clearly state in my guide, the SSDT-X299.aml was originally developed by @apfelnico for SMBIOS MacPro6,1. All credits to him! I just adopted the originating SSDT-X299.aml to my system and to SMBIOS iMacPro1,1 by following the very basics and all IOREG information available for my system, as well as by taking profit of @TheOfficialGypsy 's iMac Pro Dump.

Thank you sir! Going to attempt the same for my Z170 build :)

Hi @kgp,

I've been meaning to ask this question for a while, so sorry for rolling back to a somewhat older topic. I know you provide some overclocking guidance in B2.3 of your guide. I was wondering if this was the method you used to achieve your 4.8GHz overclock (and your current 4.6GHz OC) of if you did something else? Did you adjust any other parameters?

Overclocking seems to be a bit of a black art, so I was wondering if you had any other insights you could share.

Thanks!

P.S. I've notice that my build crashes and reboots shortly after login when using the By Core Usage option in the CPU Core Ratio setting (it's fine when using Auto or Sync All Cores). I mention this because this is how the EZ Tuning Wizard attempts to find the best overclock.

I am currently successfully running my i9-7980XE @ 4.7 GHz (max. Turbo Frequency Ratio of 47) with "CPU Core Ratio" set to "Sync All Cores" and "CPU Core Voltage" set to "AUTO". You can also set the "CPU Core Voltage" manually to 1.220V and save some degrees C at CPU max. load. I clearly advice against running this CPU @ 4.8Ghz! The CPU Core Voltages and Temps would dramatically increase. A severe damage of your CPU or mainboard cannot be excluded. Already 4.7 Ghz require a extended and sophisticated water blocking and a "delidded" i9-7980XE!

Good luck,

KGP
 
Likely a complete n00b question, but is it expected behavior that if I try to compile:

Code: 
DefinitionBlock ("", "SSDT", 1, "NICO", "X299", 0x00000000)
{

External (_SB_.PCI0.RP19.PXSX, DeviceObj) // (from opcode)

Scope (_SB.PCI0.RP19.ARPT)
{
OperationRegion (PCIS, PCI_Config, Zero, 0x0100)
Field (PCIS, AnyAcc, NoLock, Preserve)
{
PVID, 16,
PDID, 16
}

Method (_PRW, 0, NotSerialized) // _PRW: Power Resources for Wake
{
Return (GPRW (0x69, 0x04))
}

Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method
{
Store (Package (0x0E)

"built-in",
Buffer (One)
{

{

},

},

"device_type",
Buffer (0x13)

},

"model",
Buffer (0x4A)
{

},

{

"name",

DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))

I get:

DTGP implementation is missing towards the end of your code. Please compare with SSDT-X299-iMacPro.aml;)

BTW: You also missed the GPRW definition in the definition block of your SSDT.aml!

Code: 
 External (GPRW, MethodObj)    // 2 Arguments (from opcode)

last time I'll bother you with this (If I can get 1 small SSDT working I can use it as the template for further ones)
I added DTGP at the end but must have a syntax error somewhere as it's giving me the error:
6084 GPRW Does not exist at line 17
Give me one last clue? :)
