Yes, you read the title correctly. CPU-Z verified screenshots show that MSI's 790FX board has reached an impressive FSB speed of 510MHz with just regular air cooling. The MSI board is recognized as the MS-7376 and we're not quite sure which model it is, but it might be the MSI K9A2 Platinum that we wrote about here.
The processor used for the test was an AMD Athlon 64 X2 6400+ with the multiplier set at 5x and the HTT at 1x so as to remove any CPU limitations. Whether the same result will be possible on the upcoming Phenom processor is yet to be seen. DAAMIT may have a winner here, and we would certainly like to see a Phenom on a 790FX board combined with RV670XT graphics.

November is when it will all be revealed.
