It is widely known that AMD-based systems aren't particularly performing well with SuperPI performance. This was previously blamed on the architecture, though it now appears that this was simply a BIOS development limitation on AMD platforms.
Finnish overclocker the Stilt has managed to solve these optimization issues by using BIOS developers' guides, and increasing SuperPI performance. The result is a simple patch that can be run on both 32-bit and 64-bit installations of Windows.
The previous time record for a 32M SuperPI run on an AMD Richland chip was 18:15 -- the AMD A10-6800K managed to pull it off within 17:34 using the patch. While not a big difference in time, do consider that the A10-6800K APU was running at just 4.1 GHz as opposed to 5.0 GHz, and they have the same architecture.
