Unusual outcomes (3700x plus 3000mhz memory)
I tried various settings today to boost performance. My memory isn't great—Hynix CJR die, Vengeance LPX CMK8GX4M1D3000C16 8gbx2 XMP at 3000mhz. Check the outcomes: CPU-Z 5415, CB20 4621, 2133mhz CAS 15 xmp off CPU-Z 5420, CB20 4583, 3000mhz CAS 22 xmp off CPU-Z 5320, CB20 4638, 3000mhz CAS 16 xmp on. I have detailed memory specs for the last one. How can I get similar CB20 results at 2133mhz CAS 15 versus 3000mhz CAS 16? Also, a higher CPU-Z score helps. My system is Ryzen 3700X with an Asus X570 Tuf Gaming Wi-Fi.
I believe it might be due to the memory usage they require. I thought the CPU-Z benchmark tested L1 or L2 cache, yet I assumed CB20 would be more demanding. Thanks.
Cinebench scores around R15 and R20 show minimal dependence on RAM speed. This makes them ideal for demonstrating near-perfect CPU performance improvement. For more accurate results with Prime95, larger calculations are necessary—using one core per physical core (disabling HT/SMT). This is the first benchmark I recall that is mostly limited by memory bandwidth, yet the FFTs still require substantial data to fill the L3 cache. With Aida64, the photoworxx sub-test appears sensitive to RAM speed, though I haven’t analyzed its scaling behavior in detail.
Thank you! I understand how to use the trial version effectively.
