Field Note #1 @omargoa 2009-08-22

Add "SMexternalclock" and "SMmaximalclock" strings to your Extra/smbios.plist with the correct info for your CPU
Exemple for my CPU Q6600 2,4 GHz :

        <key>SMexternalclock</key>
	<string>267</string>
	<key>SMmaximalclock</key>
	<string>2400</string>

could someone confirm that in snow leopard "system profiler" no information is given regarding the various CPU extensions (sse2/3 etc..) ?

SL showed wrong cpu information that i correct with smbios.plist but i have no information about the CPU extensions...

it's normal. real mac have another cpu's,for example my penryne it's desktop but on macbook/imac mobile penryne.
So simply check processor family with xcode prefpane cpu.

Field Note #4 @cili0 2009-08-23

in Leopard system profiler shows all the CPU extensions, the SL system profiler doesn't. I'd like to know if it's normal or it isn't.

Thanks and cheers!

it's just picture in about this mac window, not info from system.
то есть херня а не фикс.

Field Note #7 @omargoa 2009-08-23

Snow leopard system profiler is different to leopard, it don't show all the information, the graphic card too don't show if the quartz graphic is supported.
But for me changing smbios correct the frequency information for my CPU

is there a solution to view full information for CPU ?

Field Note #8 @Gurruwiwi 2009-08-29

Exactly,,,

I edited my smbios.plist to read the info, for example I put DDR3 at 1066 brand Corsair, which its not (just the brand, rest of info correct), but it show up like that in profiler, except it reads DDR2.

Didnt edit anything for CPU and reads correct clock, but like this -> 2,46Ghz Unknown

. In Leo it read ram at 1067

So how can we check if CPU clocks and RAM speeds are correct? In Leo its just having the correct smbios.kext, right?

"Add "SMexternalclock" and "SMmaximalclock" strings to your Extra/smbios.plist with the correct info for your CPU

Could anyone tell me how exactly I can edit my smbios?
I dont even know wheter I have this "extra" folder and where smbios.plist is located. :-|
Would be reaaaaally nice !

Field Note #11 @Boobear 2009-09-06

( Still not working

I have an SMBIOS.plist in my extas folder, but that hasn't changed everything.
Does this method only work if you have Chameleon 2 (RC1 431, RC2 640)? I've yet to get that working with SL, and I've since had to revert back to Chameleon 1.0.12 to get SL to even boot (Netkas's PCEFI 10.1, 10.2 are not working either. I THINK I'm using v9 but I'm not too sure because it came in a SL bundle pack).

I've also tried to edit the localizable strings in System/Library/Systemprofiler/SPPlatformreport.spreporter but that just mucked everything up. I'm at my wits end, and

Field Note #12 @theta 2009-09-08

I'm wondering how to change my CPU name? Is it possible? See this picture: media.iuk koth.net/images/sl.png

Now it reports as "Unknown" (as shown in the screen)

Field Note #13 @Gurruwiwi 2009-09-11

Boobear, yes I believe you do need Chameleon 2 to get Extra folder working.
