XFX HD Double D 7870 will not allow voltage unlock... I have tried every trick there is.

[Thaggernafle]

Method 1: MSI AB /xcl

Change shortcut on desktop properties to /xcl. Takes setting changes and asked to reboot... I delete shortcut and reboot. Open AB then tick unlock voltage control and monitor in settings. Restarts AB... NO LUCK!

Method 2: Change CFG File

Go into the Directory and change in cfg file:

UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 1

STILL NO LUCK!

I went to regedit and changed eplu or what ever to 1

I do not want to beat a dead horse but my friend has his setup (Intel as mine is AMD) with absolutely no problems with same card. Other info: FX8350 CPU, XFX 550 Bronze 80 PSU, Asrock 990FX Extreme9 mobo. Please Help!!!

does your friends card have the same pcb revision?

my gigabyte 7970 is voltage locked--nothing i tried will unlock it

but earlier pcb revisions were unlocked

How would you find it?

 

[mcnumpty23]

should be written on the pcb

or if it came with software that may tell you the revision

though in my case it was easy as the first revision had a black pcb and second a blue pcb

really annoyed me as neither gigabyte or the retailer made any mention of voltage locking them

still a great card but they should be made to say if they voltage lock them

Well I have F.0, locked voltage. He has A.2, Unlocked voltage. Thanks and problem solved.. in my case. F.0 IS NOT unlockable. Maybe a BIOS update? Probably would brick it with my luck!

i have tried bios updates

have tried force flashing a different card bios on it

that gave me a higher voltage but the card was unstable

so guess you got to grin and bear it
