Consider revisiting your RAM after three years to attempt an overclock once more.
Consider revisiting your RAM after three years to attempt an overclock once more.
CPU model upgraded from Ryzen 1700 to 3.9 GHz with 1.3V air cooling. Graphics card is Crosshair VI Hero SOC, voltage reduced to 1.1V. RAM uses CMU32GX4M2C3000C15/ Corsair Vengeance White with 32GB (16GBx2) at 3200 MHz C15 memory. Memory voltage and speed changed from 1.35V @ 2933MHz to 1.3V @ 2865MHz—previously unstable, occasional crashes. Manufacturer is Hynix RAM, but the calculator isn’t working. Seeking others with identical configuration who might overclock to 3200 MHz and their settings. First-gen Summit Ridge had similar issues but different controller.
Running a Zen 1 chip indicates your IMC is at its worst, suggesting a high chance of losing the silicon lottery. If you're still interested, consider updating the BIOS and see if it improves things.
I checked numerous general Microsoft/Google PR responses and managed to figure out how to boost performance even with the limitations of Zen 1’s IMC. Just open HWINFO64 and examine the XMP profile in the Memory Module Parameter. It was surprisingly straightforward—follow the timing guidelines and tweak as needed for finer control. The XMP settings are now reliable and easy to use.
The Ryzen DRAM calculator usually gives reliable outcomes for users like me. Here are the quick timing specs for CJR on a Zen 1 board with a X370 motherboard. The only adjustments I’d make would be increasing SOC 1.05v, setting DRAM voltage to 1.4V, and keeping Gear Down Mode active for better stability. If you’re having trouble getting it stable, you might need to tweak tCL and/or tRFC, though these should align with typical chip capabilities.
