Ideal voltage settings for boosting Ryzen 1800X performance
Ideal voltage settings for boosting Ryzen 1800X performance
I usually swap out the mobo and CPU every five years, which is what I’m targeting for longevity, with a bit of value left over at the end. I’ve managed to achieve 4.0 GHz from 1.45 V, running R15’s render test near 68 °C and scoring about 1726 cb points. It fails if I go to 1.4 V or lower, but I haven’t adjusted it further since I learned that voltages above 1.4 V aren’t ideal for daily use, even with moderate temperatures. So I’ve lowered it to 3.95 GHz at 1.375 V, which is giving me roughly 1695 cbp at 62 °C, and I can run the 1344k test on Prime 95 for over half an hour without problems, averaging around 50 °C. This seems reasonable? Would you consider pushing it a bit higher? Lower it further?
1.45v is the ideal setting to push any Ryzen. It's hard to notice a difference between 3.95 and 4GHz, and upgrading to higher voltage isn't worth it unless you see temperature benefits. On the other hand, Ryzen performs better with higher RAM frequency, so increasing it slightly without affecting latency would be beneficial. Check my notes—I'm getting similar results with my 1700x at 3.825 GHz using 3000MHz RAM at Cl12.
CountMike shared his experience on the forum. He mentioned that pushing the clock speed to 1.45v for any Ryzen model would likely not noticeably improve performance, especially when considering the cost and voltage increase. He noted temperature differences as a possible indicator of effectiveness. He also reported similar results with his 1700x at 3.825 GHz using 3000MHz RAM at Cl12. He suggested adjusting the RAM frequency slightly without increasing latency to see better gains. He confirmed he's using 2400 MHz Cl16 DDR4 with a single 16GB stick, and he found an increase in both CPU and graphics performance.
I enjoy testing my systems to their limits while maintaining stability and temperature control. This is the time "Silicone lottery" activates. It affects processors and individual components, performing optimally at certain voltages and then requiring a significant voltage increase for higher frequencies. For improved RAM performance, running in dual channel with 2*8GB would be ideal. DDR4 can handle up to 1.4 - 1.5v without damage or overheating, though latency remains crucial. An increase in latency by two due to higher frequency results in minimal gains in performance.
CountMike shares his thoughts on pushing system limits while maintaining stability and temperatures. He mentions the "Silicone lottery" affecting processors and individual components, noting performance spikes at certain voltages. He suggests running RAM in dual-channel for better scores, with DDR4 capable of handling 1.4-1.5v without damage but highlighting latency's impact. He attempts to reach 3066 MHz but encounters memory errors on boot and wonders if higher voltage could help, while also expressing interest in future 64GB RAM possibilities.
You might attempt RA up to 1.45v without problems, though it's likely that CL will increase, reducing overall impact. Also, once all RAM slots are filled, RAM OC is limited, requiring a trade-off between speed and capacity.
CountMike could attempt RA up to 1.45v without problems, but it's likely CL will increase and most of the effect will be lost. When filling all RAM slots, RAM OC is limited so you might need to find a balance between frequency and capacity. I attempted to go up to 1.45 V but she can't handle more than that—it just stops working after 2933, which probably means this is the limit for this RAM type. I also tried adjusting latency in hopes of improving performance, but the numbers kept rising, so I stuck with the default settings and it seems stable. I achieved 99.4 fps on the cinebench test, which is a solid stable overclock. Thanks for your assistance.
