Hi I have issue with graphic card ..I dont see 1.5v memory and voltage GPU all voltage are PCI -E 3.3 5v 1.8v 12 v. 1.8 v bios ..Memory is around 43.0 ohm ,GPU 0.6 ohm .I test all fuses ..On RT8128C missing enable I cant found out ,from where come ..Please help..Thanks

it's bad. or memory or gpu - is dead (or both)

why you think ?I wrote wrong memory is 43 ohm no 0.43

it was a quote. if it was written 0.43, then it was. and if you misspelled it, this is different, you can edit it at least ten times - the quote will remain a quote)).
then 43 ohms is the norm. that's not the problem))
look for memory power pwm. see the availability of the enable, pwm power supply.

Yea ,but RT8128C should present voltage for memory and on 7 pin i dont see voltage 0.35 should be more ..I cant see from where come EN

Take a photo of the board on both sides in good quality. Let's try to find where the turn-on signal comes from.

Ok I did photo

I also measure on GPU controller EN 0.2v ..

))
what else did they keep silent about?
first, the power supply of the GPU should rise, and only then the memory.
what is the voltage at all pins sd8 sd9

Or should firs rise memory and then GPU?I will tomorrow check voltage..

i mesure voltage

good, but wrong.
I asked to measure on sd8 sd9, but not sq9 and sq10.

now i will do i m sory..But I cant see sd9

i mesure now..

I mark it

0,7v - it's wrong.
in green - it's result
in blue - it's cause. we must find it. use schematic in picture.

When I inject 0.9v on this coil what I mark now i got gpu and memory voltage ..I cant understand for this shematic ..

because pgood from it is a necessary condition for raising the voltage of the GPU and memory.

i cant find pgood source ..

take a foto this place. I see only light spot.

Ok I did new photo..
