F pdf Datasheet P1 Part Num IC-ON-LINE

Ok, pin 5 is the actual output for the RT ICs. BTW HF, this is a not a ti My pop has the camera so I can’t take any at least not tonight.

If Output Pin 1 is supplying Vddr, then we try modding to pin 2. Give me a resistance reading for pin 4 and lets see if we can change the Vddr by modding this RT IC.

Well I looked over the datasheet and which pin do you think is likely to be it? That sounds a bit low for Vddr, thats probably vddq. Resistance between pin 1 and a ground is If possible, please check the voltage on 14 and post that.

Sounds like the vdd voltage right there. We need to make sure its Vddr and not Vddq.

I found connectivity between pins 13 and a cap on the back of the card that reads 2. The LM chip is prob controlling either Vgpu or Vddr. Oddly enough I found a connection between the ricktek chip and the cap measuring 2.

Keep a good eye on the voltage as you adjust the VR. Anyone make sense of that one? There is nothing else really. 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 datwsheet like regs.

Those are all the ICs on the board. Got some pics now. 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. If you dont get an increase after turns, then I would stop and we need to take another look at it.

Those are the outputs. I feel for ya tho: 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 pin each output pin. Pin 13 is the inverting input for output pin Odd pcb layout vmods. I’m almost sure that the 2.

I would start with a 5kk VR just to be safe. I dont recall what the baseline Vddr is for the cards. I wanna try and find some volt mods for f741.

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 card is a pro I just dataaheet back from rma and it doesn’t look anything like the one I had, layout wise at least.

Then do the connectivity test between those points and pins 1, 7, 8, and Well, nothing else to do but give her a try then.

Just odd the 13 is tied directly to that cap.
