hello,

this board came with a dead UCL1 (SLG3NB271VTR), no chip in hand so I've tried SLG3NB3454 instead..

the board started and initialized but HDD is not detected in the bios, HDD doesn't spin-up..

3v & 5v and all pins are ok on jhdd

tried to flash the bios, nothing..
replaced all 4 caps on the data lines, still nothing..

does UCL1 affect Sata lines in any way ?

I've noticed that closing pin 18+19 on jhdd to force-on the drive leads the board to no init..

is there a chance to find a boardview ? I need help to locate RH43/RH48/RH41/RH242 & T86

SLG3NB271VTR не меняется на SLG3NB3454
у SLG3NB3454 12-я нога - CLK_27M_XTAL_IN
у SLG3NB271VTR - NC
5 - 25M/// 24M
итд.

thanks for the replay..

i know it is not compatible but does it affect operation of sata ports ?

since i don't have the slg3nb271 chip now i'm converting the board installing the clocks to no green-clocks for a test..

I also put 3454 (DAY11) instead of 271 and the same thing happens that when the laptop is turned on, it doesn't see hdd or odd. Now I'm trying to find SLG3NB271VTR or SLG3NB304VTR - (Rimas said that the laptop with that replacement works). viewtopic.php?f=54&t=54746&p=853104&hilit=%2Ala+8391p%2A#p853104

The non-green clock conversion didn't work for me, it was repaired by using the correct exact chip "SLG3NB271VTR"
