Operating System(s):	Windows XP Professional SP2 Direct X 9.0c
Motherboards:	SiS 756 Reference Board ASRock 939Dual-SATA2 (ULi M1695/1567) Sapphire A9RX480 (ATI) Jetway 939GT4-SLI-G (nForce4) ULi AP9567A (M1695/M1567) DFI LANParty UT nF4 Ultra-D (nForce4) MSI K8N Neo4/SLI Platinum (nForce4)

Tests used OCZ PC3200 Platinum Rev. 2, which uses Samsung TCCD chips. All memory ran at 2-2-2-8 timings in all benchmarks.

The NVIDIA 6800 Ultra was used for testing both PCIe and AGP performance on the ASRock board and the ULi Reference board. The 6800 Ultra video cards were tested at the same video timings and differed only in interface - AGP or PCIe. Resolution in all benchmarks is 1280x1024x32 unless otherwise noted.

SiS claims full Athlon64 X2 compatibility on their website. We were able to confirm that claim in brief operation tests with an A64 4800+. Benchmarks were run with the 4000+ 130nm A64 for benchmark comparison with other Athlon64 board reviews.

Results for the ULi chipset boards are in light blue for AGP and blue for PCIe.
