3787 Intermittent Black

GPU load gives black screen.... U9300?

Common issue that still has no clear solution. The 3 CPU FETs are my first suspects and I have a few test cases out there right now.

Direct replacements or equivalents?

 

[dukefawks]

No idea what you mean.

I replaced CPU FETs and hope and pray they are not coming back. Not proven repair yet.

I'll give it a try facing mecca

I mean are you replacing with the exact same FETs / part number (Direct replacement) or you replacing with FETs of similar characteristics (equivalent)?

 

[dukefawks]

Look at the FETs and you will understand that you can only go with the original ones.

How are we getting on with this please... Any returns yet?

 

[dukefawks]

Mine is still out there, so seems ok so far.

I'm still waiting on FETs to arrive. Did you get yours from the China man?... I ask because I have already been sent one lot of used crap which i sent back.

 

[dukefawks]

Just got 20 of them yesterday, not inspected yet.

 

[dukefawks]

Inspected and they are pulled garbage nicely sanded so it almost looks real, FUCK CHINA.

Duke, how are you checking if they're sanded? I just got in 40 chips and they look pretty good, but do have extremely light "scratches" (1 or 2, about 1/6th the width of the chip itself) on random areas of the top surface; not concentrated towards edges or anything. The bottoms look pretty good, very clean, but with 1 or 2 "imperfect" marks on the bottom of each. Hard to tell if they're from being pulled or not. Edges are all perfectly crisp, no chipping or signs of scuffing, etc. I can post photos if you would like.

 

[dukefawks]

Mine had different date codes and the edges were a bit crumbled. Also the pads on the sides of the chip should all be copper colored.

Care to name our little yellow friend selling crap FETs so we don't get shite sent to us too please?

 

[SMMRepair]

............

 

[dukefawks]

Oh God Hong Ming, they are also the sellers of the garbage AMD GPUs. Doesn't mean these chips are garbage but it does prove that they have no real clue what they are selling, you just got lucky that this batch was really new.

 

[SMMRepair]

Sorry, duke.

 

[dukefawks]

I ordered some more too from a seller that did send me 5 real new ones a few weeks ago.
