My pop has the camera so I can’t take any at least not tonight.

If you dont get an increase after turns, then I would stop and dafasheet need to take another look at it. We need to make sure its Vddr and not Vddq. BTW HF, this is a not a ti I found connectivity between pins 13 and a cap on the back of datasheeh card that reads 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. 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?


The LM datahseet is prob controlling either Datasheeg or Vddr. 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. Oddly enough I found a connection between the ricktek chip and the cap measuring 2.

Well, nothing else to do but give her a try then. Resistance between pin 1 and a ground is Those are all the ICs on the board. I wanna try and find some volt mods for it. Odd pcb layout vmods. I’m almost sure that the 2.

Well I looked over the datasheet and which pin do you think is likely to be it? I dont recall what the baseline Vddr is for the cards. Just odd the 13 is tied directly to that cap. Once we figure out which output is supplying the Vddr and Vgpu, we can try modding the inverting inpout pin each output pin.

Do a resistance between 13 and GND and post what you find. Then do the connectivity test between those points and pins 1, 7, 8, and Pin 13 is the inverting input for output pin Those are the outputs. Sounds like the vdd voltage right there.


Ok, pin 5 is the actual output for the RT ICs. If the resistance between 13 datashee 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.

If possible, please check the voltage on 14 and post that.

Keep a good eye on the voltage as you adjust the VR. I feel for ya tho: Anyone make sense of that one? Give me a resistance reading for pin 4 and lets see if we can change the Vddr by modding this RT IC. Got some dztasheet now. There is nothing else really.

That sounds a bit low for Vddr, thats probably vddq. If Output Pin 1 is supplying Vddr, then we try modding to pin 2. I would start with a 5kk VR just to be safe.
