Increase Micron Rev E performance from 3200 to 3600 memory speed Memory errors rise during the upgrade
I attempted to boost my Crucial Ballistix 2x16 3200Mhz Rev E memory to 3600Mhz using XMP timings. I set the other parameters to auto values based on the kit’s specifications. The first test with Memtest86 passed, but the second failed. For Micron Rev E, I’m unsure which setting is best—whether tRCD, tRP, TRAS, tRC, or voltage matters most. If you can avoid changing voltage, focus on adjusting those timing parameters and see what stabilizes best.
First I adjusted the voltage to 1.45 to check stability. If that didn’t help, I moved on to adjusting the timing.
I recommend trying the Ryzen Dram Calculator for a solid initial estimate.
I’d prefer not to, but I’m open to a small adjustment in timing. Maintaining longevity is important, particularly at this stage.
The Ballistix ICs remain unaffected by temperature, operating reliably up to around 70°C. Most users prefer the 1.5V configuration daily, though safety drops near 1.7V. Only frequency and tCL are directly influenced by voltage changes—raising power improves those two parameters more noticeably. The DRAM Calculator often misrepresents things; instead of focusing on CL14 tuning, consider switching to CL15 with GDM disabled. Confirm your setup by loading Thaiphoon Thruster to inspect the PCB revision or check underneath the heat spreaders for multiple DRAM wafers. Clocking performance isn’t the only concern—timings should be adjusted carefully. A standard Ballistix could easily exceed 3600 MHz, but this depends heavily on your IMCs. The main issue likely stems from suboptimal auto-timing settings. Start by loosening all clock settings significantly, especially primary and secondary timings. Modern systems prioritize bandwidth, so higher FCLK usually helps latency. Aim for a stable 1867–2000 MHz FCLK with MCLK and UCLK aligned. Adjust BIOS to set a manual FCLK of 1866, VDIMM/DRAM voltage at 1.5V, and SoC voltage at 1.15V. Use Medium LLC if needed, and consider a 1.25V supply for better stability. Avoid memtest86 due to slow error detection; prefer tools like Anta-Profile on TM5 or OCCT with SSE/AVX2 for thorough testing. Run a 30-minute SSE OCCT and 30 minutes of AVX2 testing to verify RAM, CPU, and timing health. If stable at 2000 MHz, push to 1933 or higher. For B550, newer revisions (like B550+ Dark Hero) seem more consistent with 2000 MHz. Once stable, proceed to fine-tune timings—start with tCL around 20, tRCDRD 22, and gradually tighten. If you're dual-rank, leave tRFC loose initially and focus on primary clock alignment.
No, I'm not at that speed. My capabilities are designed for a different range.
