FirePro W8100 - Terribly low performance with ECC

I experience a serious performance decrease with the AMD FirePro W8100, if I enable the Error-Correcting Code.


While all of the attached images are from synthethic tests, for the easier reproduction, the real-world numbers are almost the same. I tried all available drivers, today I installed the newest Catalyst Pro, but the same performance drop remained.

Otherwise my system is very stable, and I have no issues with any 3d-applications.


I doubt that this is normal, so either is something wrong with my card or is this a driver or operating-system related issue which can be adressed in the future?

(Currently I'm using Windows 7 Ultimate x64 SP1 with the latest updates.)


Please help resolving this problem.
