Problem is my PSU is 290W and I am not looking to upgrade the machine as its a server with proprietary connections to the motherboard a third party PSU wouldn't work for this scenario
I have a SATA pin to 6 pin connector but I dont want to have to deal with black screens or instability issues from power draw
I aware of Wattman and just heard about SRBPolaris Bios Editor
I just want to be able to run the card at like PCI-E slighty lower than max power settings(75W correct?) but I am willing to use the 6 pin connector I just dont trust the 12 draw for this powersupply under load. I just want it to be able to run off PCI-E only with the 12v as a emergency suppliment for spikes.
I plan on using it for gaming.
What settings would be stable and accomplish this? I am aware there are probably BIOS already for it but its the DVI only edition which makes it necessary to manually edit.
I was able to unlock this card to a full 560 just using these steps
it is a default 45w card but i got it to run stable at 30w with 1100 gpu /1625 memory
ill also upload the modified bios where the shaders are unlocked to a full 560 for this powercolor model with DVI only. This is just for my card. You can use the instructions below to see if your 560 2nd edition/560d can be modified
1 -Open your BIOS with an Hex editor(HxD), then:
a) - Press Ctrl+F
b) - Search for 6F 22 70 22 in hex form
c) - Replace 6F 22 70 22 for 6F 22 6F 22.
d) - Save BIOS Crtl+S.
2 - Correct BIOS checksum:
a) Open BIOS with Polaris Editor
b) - Save BIOS.
3 - Flash BIOS (ATI ATIFlash / AMD VBFlash)
4 - Run Atikmdag Patcher(important)
5 - Restart PC.
6 - Enjoy it if you have an unlocked card. :toast:

If you can't find the string values, you might need to save as the default format like 560.rom instead of 560bios.rom. I loaded one of my original dumps and the hex editor couldnt find the values when i didnt save the rom dump properly. You can try SRBPolaris to try to dump rom as well.
