Current settings according to BIOS:

Target CPU Speed: 3400MHz

Target DRAM Frequency: 800MHz

Target FCLK Frequency: 1800MHz

DRAM timings: 19/20-19-19-19-39

(The DRAM CAS# Latency setting is set to 19, but "CHA" and "CHB" show 20. I don't know what this means exactly.)

So I think you're right, scns. I was not getting the best performance.

I changed FCLK to 1900MHz and re-ran the Linux C++-vs-Rust benchmarks. Some results:

build+test w/o deps: 1847ms Rust, 1874ms C++ --> 1801ms Rust, 1837ms C++

incremental test-utf-8: 288ms Rust, 358ms C++ --> 280ms Rust, 350ms C++

So I did get a performance win for both C++ and Rust builds by fixing my FCLK. Thanks!
