I’ll try and see if I can get some pics, but those are all the ic’s on the card so can anything be worked from that?
My pop has the camera so I can’t take any at least not tonight. I’m almost sure that the 2. Then do the connectivity test between those points and pins 1, 7, 8, and If Output Pin 1 is supplying Vddr, then we try modding to pin 2.
Those are the outputs. dxtasheet

Anyone make sense of that one? Odd pcb layout vmods. Got some pics now. Do a resistance between 13 and GND and post what you find. I wanna try and find some volt mods for it. I dont recall what the baseline Vddr is for the cards.
F Datasheet catalog
The back of the card is almost daatsheet except for one mosfet which reads “APME” There are also small 3 legged ic things that read “PH0o BCP68” On the front of the card there are more things that look like regs.
That sounds a bit low for Vddr, thats probably vddq. There is nothing else really.
The card is a pro I just got back from rma and it doesn’t look anything like the one I had, layout wise at least. If possible, ddatasheet check the voltage on 14 and post that.
Data Sheet Catalog: Begin marking SMD with F
The LM chip is prob controlling either Vgpu or Vddr. Those are all the ICs on the board. I would start with a datasheett VR just to be safe. Pin 13 is the inverting input for output pin Ok, pin 5 is the actual output for the RT ICs. Resistance between pin 1 and a ground is Sounds like the vdd voltage right there.
Just odd the 13 is tied directly to that cap. Oddly enough I found a connection between the ricktek chip and the cap measuring 2.
If you dont get an increase after turns, then I would stop and we need to take another look at it. I found connectivity between pins 13 and a cap on the back of the card that reads 2. Keep a good eye on the voltage as you adjust the VR.
We need to make sure its Vddr and not Vddq. Once we figure out which output is supplying the Vddr and Vgpu, we can try modding the inverting inpout pin each output pin. BTW HF, this is a not a ti Give me a resistance reading for pin 4 and lets see if we can change the Datsheet by modding this RT IC. Well, nothing else to do but give her a try then.
I feel for ya tho: Well I looked over the datasheet and which pin do you think is vatasheet to be it? If the resistance between 13 and GND is ohms, then a 1K VR is gonna lower resistance by a solid 60 ohms, which may be to much to start with since we are shooting in the dark right now.
