Your Ryzen 5600x seems to be acting strangely.
CPU: 5600x | GPU: 6800xt Taichi | RAM: 16gb 3600mhz Safe OC at CL16-17-17-34 | 850W PSU | CPU cooler: Coolermaster 360R AIO I’ve been using this setup for a year now, with the new GPU (6800xt coming from a GTX1080) for gaming. I realized my frame rates weren’t matching expectations, so I did a RAM overclock after discovering the CPU wasn’t performing well. The Cinebench R20 score was 3563. Thermals stayed low at around 65°C max and power consumption was between 60-63W using a 360mm AIO cooler. What should I do next? UPDATE: With PBO enabled via Ryzen Master (and also in BIOS), I reached a 4061 R20 with lows at 3934. I’ve attached the Ryzen Master monitor view and some HWiNFO notes about the CPU.
Enable PBO or manually apply a stable overclock to your CPU (any frequency that runs smoothly around 1.25-1.3v, no need for higher voltage since returns drop sharply after a point, should handle ~4.5g). And it seems RAM won't help much if you only adjusted the minor primaries rather than key timing parts like TRFC, SR DR DD, and TREFI (set to 65536 for peak performance), limit RAM usage to 1.45-1.5v to avoid instability from excessive heat if fans aren't running due to issues.
AMD doesn't allow changing that timing, it's exclusive to Intel. That assumption isn't reliable. Parameters like CJR shouldn't exceed 1.4V daily without risking unexpected failure. For B die or DJR especially, 1.45V–1.5V works, but some ICs won't handle those voltages even for high speeds like 3600MHz CL16.
Interesting point not made before—why can't it be adjusted? Could CJR randomly fail at around 1.4v or are those just exaggerated claims from a few people? I’d say it’s probably just random failure, similar to what happens in Elpida Hypers. It seems like death is usually instant due to extreme heat (over 125°C) or high voltage (above 2.1V), but I haven’t heard of any situation where it depends on specific factors. I’m skeptical about these claims being real, since random death feels more like a coincidence than a pattern. Would be cool if many people had proven this isn’t just speculation—otherwise, with newer OCs like Samsung C-DRAM or even Micron 8GB, it’s unlikely to be safe. The rest of the 8Gbit dies (excluding C and S) or Hynix DJR would be safer options. Also, with that Samsung chip, you can quickly check if voltages beyond 1.45V are safe, otherwise it might not run at all.
Yes, it is possible to log data during a run to capture information for later analysis.
It seems your setup is quite outdated. The 3600C17 was once popular but now max voltage is limited unless cooling is sufficient. If you're aiming for higher voltages, you'll likely need to reduce RAM capacity—halving RAM usually brings you to the maximum. Above 1.75V is risky; aim for 1.6V or lower to avoid overheating and potential errors. For better performance, consider lowering TRFC and SRDR timings if possible. Target voltages between 3800-4200 depending on your clock speed, though stability drops around 1.2-1.3V due to IMC issues. You might want to test C14, C15, and C16 first before moving to lower speeds or voltages. Keep adjusting until you reach the point where further increases become impractical.
They claim it becomes inactive after roughly a week when operating at 1.45V. The chances aren’t worth taking. You’d need to contact AMD directly. While technically possible, there’s no method to alter it. Intel and AMD differ in several timing options; for example, tWR isn’t available on Intel but exists on AMD.
