I found connectivity between pins 13 and a cap on the back of the card that reads 2. Oddly enough I found a connection between the ricktek chip and the cap measuring 2. Anyone make sense of that one? I dont recall what the baseline Vddr is for the cards. Got some datasheeh now. 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.

That sounds a bit f7143 for Vddr, thats probably vddq. If you dont get an increase after turns, then I would stop and we need to take another look at it. Ok, pin 5 is the actual output for the RT ICs.


Give me a resistance reading for pin 4 and lets see if we can f7143 the Vddr by dqtasheet this RT IC.

I feel for ya tho: If Output Pin 1 is supplying Vddr, then we try modding to pin 2. The back 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.

Resistance between pin 1 and a ground is My pop has the camera so I can’t take any at least not tonight. We need to make sure its Vddr and not Vddq.

If possible, please check the voltage on 14 and post that. Well, nothing else to do but give her a try then. Those are all the ICs on the board. I wanna try and find some volt mods for it.

There is nothing else really. 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, which may be to much to start with since we are shooting in the dark right now. BTW HF, this is a not a ti The LM chip is prob controlling either Vgpu or Vddr. Sounds like the vdd voltage right there. Just odd the 13 is tied directly to that cap.


I would start with a 5kk VR just to be safe. Once we figure out which output is supplying the Vddr and Vgpu, we can try modding the inverting inpout pin each output pin.

Odd pcb layout vmods. Well I looked over the datasheet and which pin do you think is likely to be it? Do a resistance between 13 and GND and post what you find. 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?

I’m almost sure that the 2.

Those are the outputs. Keep a good eye on the voltage as you adjust the VR. Then do the connectivity test between those points and pins 1, 7, 8, and
