this is pcb to card

thanks!!!
31:00 would be the low
and 63:32 would be the high?

yes

so I think I understand how mats reading works, thanks again.

I will bring the result
Posted after 3 hours 7 minutes 59 seconds:
hello again, I have a doubt ... the memories of this card are elpida W4032BABG-5-F
is it possible to replace with samsung K4G4132FC HC03? if possible, do I need to replace the pair? or just one

---

Posted after 1 hour 59 minutes 7 seconds:
I managed to find an identical module, replace it and guess what? msm remains 33 writing errors ...
next step? reball?

I left the card for 7 hours at full mark and she no longer presented the single color screen, but I noticed that she is only giving video through the dvi output, with no video signal via hdmi.
suggestions?

hello, after reball to gpu the card 100% functional!
thanks everyone.
