I EPowered a reference Radeon HD 5870 and have been running into problems getting it to work. The OS I'm booting into has the correct video drivers as I installed them prior to the mod. Initially I wasn't able to get any picture but the system would boot up fine (as I could tell via boot codes, drive activity, and leds on my mouse n such). Then I looked up the memory's voltage and used 1.5V for that and I initially got picture, but it blackscreened whenever I got into the OS. I could sometimes see flashes of picture if I jostled the card around a bit but could never figure out if it's my mount or my PCI Riser cable. Right after rebooting a few times my system went into complete automatic shutdown right after hitting the power button. As in press power button -> automatic shut off. Honestly thought I killed my system. Had to revert back to my 1660Ti and reflash my motherboards bios to get my system to work again. Now after plugging it back in it boot loops after getting to code b2 (Asus Crosshair VIII Hero) even after a cmos reset. Even weirder when I go back to using my 1660Ti I get the post screen error in the last photo attached to this post. No idea what it could mean. Tried using 1.163V (which appears to be stock) and 1.35V (max the slider would go prior to epowering) for the core. Also tried remounting my waterblock and cleaning the pci fingers. I'm also making sure to apply the correct voltages as soon as I possibly can when I hit the power button. Did I kill the card or is there something I need to do to the vc to mod it correctly? I've seen another guide about voltage mods and he didn't mention anything additional about the vc in both of his posts on this card.
Hey guys, i have recently spent lots of time figuring out vMod for GTX1060 6GB and also other Pascal uP9509 based GPUs, as this VRM IC doesnt support i2c bus, rather than that it utilizes PWMVID tech. Also BIOS mod isn't that easy on Pascal. Yesterday i managed to find picture with pinout for the VRM IC, also tried vMod on my GTX1060, works just fine, although didn't test yet beyond 1.2v as there was no more time left. GPU seems to scale a bit, managed to get 2180mhz from previous 2100Mhz max. During the weekend will bench the GPU to see what is it capable of, wish me luck If anyone wants to know how to do HW power mod on Pascal, you can just do the same thing as I did> solder 10ohm resistors on top of SMD caps around INA3221. You can also use 0805 SMD resistors, so it wont look as bad, but i dont bother much Hope the IC pinout will help someone also if u have any ideas feel free to share. Will appreciate Happy clockin"
Well, since EVBOT having transition state currently, here's alternative solution for you, EPOWER people. Since controller accepts controls from PMBus, attached Raspberry Pi can talk to EPOWER and adjust voltages. Voltage range is 0.6 to 2.0V Tested with Model B Rev2.0 (not plus), but should work with any Pi. Details in this article for those who interested. Try it, and let me know if any problem Also old-school hardware-only way with trimpot resistor is covered too.
