Hi folks

New to the forum. Breaking ground with 980x. OSX-10.6.4 new kernel now supports 980x and it works great but I have two questions that I need help with.

1.) I am looking for the smbios CPU code for 980x. I am using 1793 which gives me "Unknown Processor" in system profiler. Anybody know the correct code for 980x?

2.) I am using the legacy kernel now because when I use the new 10.6.4 kernel the time clock runs really fast, causing some system issues. I am using chameleon RC4. Anybody know what might be causing the clock to run fast and how to fix it? running native 10.6.4 now with modified boot.

I am open to suggestions.

Any help is appreciated.

Powel

Additional info:
GA-EX58A-UD5 - GTX-260 - Base clock 166, CPU-4Ghz
DSDT is board specific and clean, running newest FakeSMC.

Not sure if it helps but try other bootloader.

Powel, I'm looking to buy a 980 setup. Does the 980 setup work?

Hi all.

As Slice say You have to try other bootloader.
This "function" is cosmetics...

You need a solution like this in your sourcecode in the bootloader

CODE

diff --git a/Booter/i386/libsaio/cpu.c b/Booter/i386/libsaio/cpu.c
--- a/Booter/i386/libsaio/cpu.c
+++ b/Booter/i386/libsaio/cpu.c
/* Nehalem CPU model */
- if (cpu_family == 0x06 && (cpu_model == 0x1a || cpu_model == 0x1e))
+ if (cpu_family == 0x06 && (cpu_model == 0x1a || cpu_model == 0x1e || cpu_model == 0x2C))
+ // 0x2C is the model 44 in decimal value, but for the i7 980x you stillneed 1793 in the  smbios.plist
{
	msr = rdmsr64(MSR_PLATFORM_INFO);
	currcoef = (msr >> 8) & 0xff;
	msr = rdmsr64(MSR_FLEX_RATIO);
	if ((msr >> 16) & 0x01)

The 980x works natively with 10.6.4 but yah you have to modify the bootloader or use one that has been modified.

Mine came from here.

Without the bootloader mod the clock runs really fast. but no other issues.

So the model number Fabio has in the code: 02xC is the right one? Or will http://www.tonymacx86.com/viewtopic.php?f=...amp;hilit=+980x patch everything correctly? What motherboard are you running?
