Both boards were socket AM3+. If you relax and comprehend......., some 890FX are AM3.
The only negligible difference is 6.4GT/s hyper link over 5.2GT/s. I put them under benchmarks and extreme overclocking. No difference and there is nothing in 990 chipset that benefits Bulldozer.
I just finished the 890FXA-UD5 and 990FXA-UD5...........
Okay, let's just get this straight: were you using a currently available
Phenom II AM3 CPU or were you using an engineering sample Bulldozer CPU that somehow leaked?
If you were using a currently available Phenom II, it makes sense that you had the same performance on the 890FX and 990FX motherboards. However, AMD has stated before that Bulldozer CPUs will operate optimally
on new 9-series motherboards with true AM3+ sockets; however, certain
(but not all) existing AM3 motherboards will be Bulldozer-compatible via a BIOS update, but will likely not match the performance of the newer motherboards with a true AM3+ socket and 9-series chipset.
