Oddly enough I found a connection between the ricktek chip and the cap measuring 2. Ok, pin 5 is the actual output for the RT ICs.
Those are the outputs. BTW HF, this is a not a ti I’m almost sure that the g7413.
I wanna try and find some volt mods for it. The ratasheet of the card is almost blank 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.
I would start with a 5kk VR just to be safe. Got some pics now.
The LM chip is prob controlling either Vgpu or Vddr. Just odd the 13 is tied directly to that cap. Then do the connectivity test between those points and pins 1, 7, 8, and Pin 13 is the inverting input for output pin If the resistance between 13 and GND is ohms, then a 1K VR is gonna lower resistance by a solid 60 ohms, datashheet may be to much to start with since we are f4713 in the dark right now.
We need to make sure its Vddr and not Vddq.

Anyone make sense of that one? My pop has the camera so I can’t take any at least not tonight. Resistance between pin 1 and a ground is I dont recall what the baseline Vddr is for the cards. I feel for ya tho: Keep a good eye on the voltage as you adjust the VR. 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. Those are all the ICs on the board. Odd pcb layout vmods. That sounds a bit low for Vddr, thats probably vddq.
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? Well I looked over the datasheet and which pin do you think is likely to be it?

If you dont get an increase after turns, then I would stop and we need to take another look at it. Do a resistance between 13 and GND and post what you find. Once we figure out which output is supplying the Vddr and Vgpu, we can try modding the inverting inpout dataseet each output pin.
There is nothing else really. I found connectivity between pins 13 and a cap on the back of the card that reads 2.
If possible, please check the voltage on 14 and post that. Sounds like the vdd voltage right there. If Output Pin 1 is supplying Vddr, then we try modding to pin 2.
