System Name Sonido
Processor E6600 @ 3.20 GHz (1600 FSB)
Motherboard abit IX38 QuadGT
Cooling Tt SpinQ (load @ 29c)
Memory TopRam SpeedRAM A.K.A "El Cheapo" @ 800 MHz
Video Card(s) Diamond HD 4870 (@ Stock)
Storage Primary: 500 GB WD
Display(s) 32" Samsung 1080p HDTV
Case Antec Twelve hundred (Modded Tri-cool fans)
Audio Device(s) On-board HD Audio
Power Supply 700W Rocketfish
Software Vista\7\Linux\Hackintosh
*Edit 1*: I added a whole bunch of new info.

When LEDs are on(lit) they mean:

HD 3870 LEDs

R53 Green Led Off - shows critical temperature fault
MR53 Red Led On - shows External power connector was removed

------------------------------------------------------------------------------------------------------------

HD 4850 LEDs

D1601 - Over temp protection enabled

D1602 - EXT 12V fault

------------------------------------------------------------------------------------------------------------

HD 4870 LEDs

D1601 - Red LED On, shows critical temperature fault

D1602 - Red LED On, shows External power connector A was removed

D1603 - Red LED On, shows External power connector B was removed

D601 - Red LED On, shows critical Core power fault

------------------------------------------------------------------------------------------------------------

HD 4870X2 LEDs

D14 (R753) 6 Pin power unplugged

D13 (R724) 8 Pin power unplugged

D15 (R819) Overheating (Thermal issue)

D5 (R323) GPU-1 (Master) No power

D7 (R570) GPU-2 (Slave) No power


At BOOT/POST, the card's fan will spin @ 100% for a short while, the LEDs will light up for a brief period and then go out. This is NORMAL behaviour as the card is performing it's own type of POST test.

------------------------------------------------------------------------------------------------------------

HD 4850X2 LEDs

D1601 : ASIC CTF Enable (GPU overheat protection)

D29 : 8 pin external connector no power

D30 : 6 pin external connector no power

D25 : Boot up fault LED (Re-plug the VGA board or D1601,D29,D30 all failed)

D1250~D1252 : Turn on with normal behavior in the left ASIC

D1253~D1255 : Turn on with normal behavior in the right ASIC



At BOOT/POST, the card's fan will spin @ 100% for a short while, the LEDs will light up for a brief period and then go out. This is NORMAL behaviour as the card is performing it's own type of POST test.

Green LEDs lit mean the VGA card is working normally. A RED LED will show on D1250~D1252 / D1253~D1255 to show normal operation.

------------------------------------------------------------------------------------------------------------

HD 3870x2 LEDs

D25 : ASIC Thermal fail / Overheat

D32 : VDDC_G1 power fail / Master ASIC VDDC fail

D34 : VDDC_G2 power fail / Slave ASIC VDDC fail

D28 : External A power fail / 8 pin External power fail

D31 : External B power fail / 6 pin External power fail

At BOOT/POST, the card's fan will spin @ 100% for a short while, the LEDs will light up for a brief period and then go out. This is NORMAL behaviour as the card is performing it's own type of POST test.

------------------------------------------------------------------------------------------------------------

HD 4890 LEDs

D601: VDDC_FAULT

D1601: critical temperature fault

D1602: AUX Hot Plug/Unplug Fault (upper connector)

D1603: AUX Hot Plug/Unplug Fault (lower connector)

At BOOT/POST, the card's fan will spin @ 100% for a short while and 3 of the 4 LEDs will light up for a brief period and then go out ( D601 should remain unlit ). This is NORMAL behavior as the card is performing it's own type of POST test.

============================================================================================================

I will continue to update this with more information. Not only will it be on the LEDs, but I will also update with other helpful information for diagnosing problems (might come as different threads, depending on topic).

Added lots of info.
 
very nice work my friend , really interesting thread
 
no 4770s? :laugh: :nutkick:
good job :toast:
 
Excellent, very helpful mate :)
 
this needs to be pinned

4770 is pretty much a crippled 4870. Still, it's a great performer, though.

2x 4770 = 1 1/2 4870
