[Ret Sticky]Overclocking sndbx for A64 939 systems with Winchester, Opteron dual core
Here is discussed overclocking A64 939 system(s) for Winchester and beyond (Venice, San Diego, Telodo (dual core), ...). Setup, benchmarking, experiments and results, overclocking and optimization techniques, issues and resolution, ... are discussed over time.
Results of a Winchester 3000+ and a DFI LP UT NF4 Ultra-D are posted. Testings, tuning is being done over time, and the evolved system(s) will serve as a 939 testbed through Winchester and follow on.
The techniques used for the Winchester 3000+ and DFI NF4 Ultra-D can be applied readily to Venice/San Diego, ....
Suggestions and comments are welcome.
May 2006, Opteron 939 dual core results have been added.
