Posted April 26, 20169 yr Good evening a need a big help my GTX580 Matrix start to go @ 640x480 at boot until SO and, a few seconds later, black screen the v mem is fixed to 1,35V, not increase to 1,57V the bios is original (flashed again) Do I can solve with a v mod on mems' IC? Where is it? If it stay between pciex 8pin and mems' vrm, there I can see an uP6205A IC Sorry for my horrible english, thank to everybody in advance

Where is it? If it stay between pciex 8pin and mems' vrm, there I can see an uP6205A IC Sorry for my horrible english, thank to everybody in advance it looks like the feedback pin on that IC is 11 but I'm not sure about your issue or if this will help.
April 26, 20169 yr Author it looks like the feedback pin on that IC is 11 but I'm not sure about your issue or if this will help. yes, datasheet says pin 11 = FB Is that IC the mems' IC?
April 26, 20169 yr yes, datasheet says pin 11 = FBIs that IC the mems' IC? it looks like it is but I'm not really familiar with the asus 580, I only have 580 classy and 580 lightning, both with voltage control, Since that card is a matrix there must be a way to raise the voltage without doing a vr mod, I just never looked into it. I can try and find out for you. But there must be a different issue going on.
April 27, 20169 yr Here you go vgpu http://i.imgur.com/CBYVpp0.png vmem http://i.imgur.com/gUoXZL1.png Edited April 27, 20169 yr by dhenzjhen
April 27, 20169 yr Author Here you govmem http://i.imgur.com/gUoXZL1.png thank you very much last night I found that point grabbing a bit the pcb near the FB do You think the v mod can solve the issue? It seems that gen the vga must run 3D the vmem doesn't gain to 1,57V and so I have black screen
April 27, 20169 yr I had this issue on other board , check other output,for me one pin from DVI was not making contact,same stuck on 640x480 and black screen,fixed the DVI and cleaned up,all fine. Don't mess with volt-mod in this matter , will not help for sure !

April 27, 20169 yr Author sadly the issue is with the vga, later I'll post a screen thanks to everybody for the kindly help
