Moving to the important stuff now; testing the board. Today we have on the chopping blocks our MSI Dragon reference board for the AM3 based CPU's which supports all current AM2+ CPU's and is again based on the 790GX chipset. This is compared with the Sapphire board to see just what can be accomplished.


Stock settings were done with the memory at 1066MHz which is the highest you can support using AM2+ processors without overclocking. The MSI board wasn't overclocked as it's a bit problematic with FSB adjustments, but we did clock up the Sapphire to 220MHz FSB, keeping the default multiplier and introducing just a slight voltage bump.

As always, EVEREST is the first on our list. Both setups at stock perform identically thanks to the memory controller being on the CPU die. AMD has done a fantastic job optimizing DDR2 memory performance on their processors. We see that with the overclocking there is an expected jump in memory bandwidth.
