AMD Infinity Fabric & RAM Overclock for Ryzen 3 3100 vs. R3 3300X (Benchmarks)

Tuning the AMD Ryzen 3 3100 Infinity Fabric clock (FCLK), uclock, and mclock, alongside memory tuning, was our next step to trying to beat the AMD Ryzen 3 3300X CPU.

In this content, we’ll talk about the settings used (and process used) to tune AMD’s Ryzen Infinity Fabric clock, with a pointer toward the above-linked video for additional information on the topic. Ryzen is touchy, and it’s easy to get worse performance by increasing the wrong numbers without maintaining a fixed ratio. We keep a 1:1:1 ratio for our best tune, so that’d include FCLK, MCLK, and uCLK. We’re benchmarking the R3 3100 with 3666MHz memory, as opposed to our standardized 3200MHz kit. We have some IF-only overclocks, barring a memory change, just to set the stage for expectations. Keep in mind that run-to-run variance, standard deviation in test data, and general error can muddy the waters in some tables where results are very close together. We’ll point that out as we go. The R3 3100’s 2+2 CCX design (2 cores, 4 threads per CCX) includes a latency hit that the 3300X’s 4+0 single-CCX doesn’t have to deal with, but it also means a splitting of the cache across two CCXs rather than being all located on one monolithic block.
