So I just made major step towards making the R9 Fury volt mod guide. I have revived the R9 290X Windforce which I killed and managed to get it's VRM under manual control.
Now most of you might be sitting there going DAFUQ How does volt modding an R9 290X have anything to do with volt modding the Fury?
It's simple. The Fury and R9 290X use the same exact voltage controller. If I manage to control the IR 3567B on the 290X it makes taking control of the IR 3567B on the Fury that much simpler.
The first thing I learned about the IR 3567B is that it's pretty smart. So smart, that the damn thing will not let the card run if it doesn't sense current on the VRM phases. With most GPU voltage controllers you cut the power sensing lines and they just ignore the fact that the current reading of 0.8A is wrong and continue running the VRM like nothing's changed. Not the IR 3567B, no the IR 3567B shuts the card down if it sense 0A on the phases. So after I tore all the SMD 300ohm ISEN resistors off the card in hopes that I would remove all power limits. I ended up resoldering every single one of the damn things. However I don't have SMD 300ohm resistors and so I improvised to end up with an R9 290X that looks more like a modern art piece than a GPU.
I also managed to under volt mod the card so it ended up running at 0.56V idle instead of the 0.968V that it should idle and boot at and so naturally it didn't work. I managed to fix that too and the card now boots and runs. At least on stock voltage I haven't tried overvolting it yet because the Windforce cooler no longer fits and I've run out of Seidons to ziptie on to it(it might sound like a terrible idea but the Seidon 120V rev2.0 can keep the 290X sub 70C even with 1.4V and at 55C when running stock volts and clocks).
Either way after this volt modding adventure modding the Fury will be a walk in the park.... I hope.
PS I'm very much aware that the AMD 125W CPU heatsink can't cool an R9 290X however I needed a cooler that could keep the GPU running long enough for me to get to the BIOS and it did that so you can keep the comments about me being an idiot to yourselves thank you very much.
Thank you to Cooler Master for powering this blog by giving me a V1000 PSU.

We understand the cooler, you just needed space to work on the PCB without removing all that thing over and over again.
ReplyDeleteHello partner, I have seen your explanatory video and followed to your blog, I have reported a bit about this but it is not clear to me whether it is possible or not to lower these tremendous temperatures of the VRM, which even with factory frequencies usually range between 69 and 75Cº.
ReplyDeleteCould you advise me on some scheme, components to change or if I directly throw this controller in the trash? Thank you!
