From what I have read on this it's upwards of some 10% or so gain in synthetic benchmarks though in actual games the difference is rarely over 5% at best (If even that.), I wouldn't bother due to the risk involved but if the tool reports the deactivated units being in the right place and unlocking is possible well even if low it's still a performance gain. (Though will it be stable? You won't know until after you've flashed the GPU although from what I heard a lot of the Fury GPU's are fine for flashing though on some the units were de-activated due to failing testing so yeah it's a risk but for all I know it might be pretty small.) http://www.overclock.net/t/1567179/...iji-unlockability-tester-ver-1-6-and-atomtool
No i don't own a fiji gpu, but i read the forums. It is pretty much why everyone went for the fury rather than the fury x. Because they can be unlocked and you have a full fiji for less. I suggest starting with 2 cu at a time and work your way up and each time test for stability. Do more research and see how it goes, might be worth it for you. Many try to squeeze at least 1-2 fps through overclocking and using bios from other gpus. You on the other hand have it already, just need to unlock it
ya I was thinking that if it worked I'd get pretty good results especially in xfire. I think I will try it today.
you have fury in crossfire and want to flash it to fury x? Why would you do that? I mean definitely you don't have problems running any game at 4k, so again why?
My card could be fully unlocked and I am running like that for the last two weeks. No artifacts, even overclocked 1150/550Mhz (with a slight voltage increase). My card is something odd. At stock CU configuration, with a good voltage increase I was able to benchmark it at 1200Mhz. Enabling 60CU's, 1200Mhz artifacts no matter how much voltage I would apply. I did not even bother testing with all 64 CU's enabled. In the end of day, results are somehow disappointing, Difference is at best 5%. http://www.3dmark.com/compare/fs/7145549/fs/7117532
@OP Personally I'd see no point in flashing Fury to Fury X. I'd use the unlocked ROM created by TX12's AtomTool. Reason being is PowerPlay section of Fury vs Fury X differ (excluding GPU clock):- i) on Vddc/Vddgfx lookuptables within it for setting VID per DPM. ii) on Fan Table, Advanced fan mode is used on Fiji by default aka "Fuzzy Logic". There maybe other differences, only recently started Fiji bios mod. Here is link to my 3DM FS compare of genuine Fury X vs Fury with 3840SP unlock.
