I propose to publish here known SMC keys or presumably known to customize with FakeSMC.

1. ACID - AC adapter ID
I wrote <44414243 4546> and obtain

CODE

AC Charger Information:

  Connected:	Yes
  ID:	0x0004
  Wattage (W):	100
  Revision:	0x0005
  Family:	0x0044
  Serial Number:	0x00434241
  Charging:	No

Where it is easy to see what is what. Wattage 100=0x64 may be from last two digits. Really it is 65W.=0x41
Then I change last digits to 0x14

CODE

AC Charger Information:

  Connected:	Yes
  ID:	0x0001
  Wattage (W):	68
  Revision:	0x0005
  Family:	0x0044
  Serial Number:	0x00434241
  Charging:	No

2. RPlt - platform string.
I found that this key together with EPCI used by AppleIntelGAMX3100FB.kext to load GPU PSS states.
Possible values
0x31376D = m71
0x30374D = M70
0x3954 = T9
0x36334B = k36
0x32384D = m82
0x4136334B =K36A
No matter lower or upper case.
I think it is Intel CPU family
M71 = Mobile T7100
M82 = Mobile T8200
T9 = T9x00
May be I am wrong. But I set for my (Dell Inspiron 1525 T8300) the key=m82. Without it I got rarely panic

GPU Page Table Error...

iMac10,1: RPlt="k22"

MBP3,1: RPlt="m75"

3. EPCI
Used together with RPlt to load GPU PSS states and influence on Voltage step.
If value < 3 then step=25mV else step=50mV
So I set
EPCI = <01>
I checked my GPU temperature with FakeSMC 2.7 and found it is cool.

Other keys?

Here is a some kind of list of keys. Look, please.

I want to see reports like "When I set key ABCD = 12345 I got a new property...."

Hi.
If can help I post the smckey from a iMac11,1.

You don't happen to have a datasheet of current keys?

Really enjoying all of the work you are doing, thx.

Thanks a lot for these information, cause the two keys have no effect under 10.7, but influence a lot on the Lion. I mean people have x3100 graphics card get the freeze issue, all the thing stop working except cursor, and it happens randomly.
After follow your suggest to edit the two keys, solve this issue. Now it works like a charm.

hi,
some info to handle smc keys from an appleforum..https://discussions.apple.com/thread/2372777?start=135&tstart=0

Here is the raw data from selected SMC keys. The format is:

Key_name [data_format] optionaldecimalvalue (hex_value)
Fan speeds [fpe2]: Decimal numbers are RPM; hex numbers are RPM X 4.
Temperatures [sp78]: Hex numbers are degrees C X 256 decimal.

read any single key.

./smc -k TA0P -r
TA0P [sp78] (bytes 10 75)
which is 4213 decimal, divided by 256 = 16.46 degrees C ambient temperature, which is reasonable as I just woke up the system and it's cool in the house.
