I've got this 3070TI that only lit up at boot (no fans and not seen by PC). When taking it apart I noticed the PCIe GPU power plugs to the GPU had pin 3 from the top of the card pushed out of the connector. Once I got the pins realligned I put the card back together to try it again. Now it lights up and the fans come on but the PC does the normal single beep for boot and right away does three fast beeps and fails to boot. I unplug the card and the PC boots normally again. Clearly another issue with the card. Anyone see this before? Feel like some progress...

Nevermind, switch different speed profiles. Got it.

My new memory chips should arrive shortly and I'll try those. I have a cheap t862++ IRD or a much better Air reflow station, any thoughts which way proves easier to reball these? ***Also what the heck does this SW1 on the Gigabyte 3070 card do? I just got another 3070TI card which isn't being recognized and can't run MATS and I noticed that this switch is opposite of what the picture below shows???

Got MATTS to run. Showing bank A0 about 10 bits bad but B1 is all showing bad. Right next to each other. Thinking to try reflow before full reball. What temp solder do you find best to try. Air station temp 415c ish? 60% air? Preheat plate 100c?...

I don't know the history on the card but at the key there is a small chip, see below. Looks like trace B10 3.3v and B11 React, A1 12v and A11 Reset is a little short but looks like it could still make contact. Here is exactly what it does. I was installing windows on a test PC to use with this, the card did put out video at that time uing the standard GPU (was an old version of Windows 10- v1510). Nvidea driver update said that op was too old for the latest driver so I updated to the latest windows 10 version. After fully updated Windows 10 was finished it doesn't put out video at all now.

Hello,

I am a novice wannabe for electronic repair. I've repaired a few of my crypto mining boards but looking at some GPU's now. Definitely will need some pointers as I try to learn. Appreciate any and all help!
