Ram Profiles and Overclocking RYZEN

[Bruno_A]

Hey, guys, I recently built myself a RYZEN system and I'd like to learn more about RAM timings and profiles, as well as overclocking. Basically, my RAM Kit is a 4x4 GB 3000MHz Corsair C15 kit, although, it runs at 2666MHz until I set it to Profile 2 on the A-XMP memory setting. it also sets the timings to the advertised 15-17-17-35, however, it sets it to 1.376V (I think) at 2933MHz, and as I can see in the Corsair website, the RAM is rated for 1.35. Why does A-XMP set it to 1.376? Does it affect lifespan? Also, I was able to reach 3.80GHz on my RYZEN 5 1600 without changing the voltage and it sits comfortably at 70C in Aida64, I tried 3.90GHz and even 3.85GHz without touching the voltage but it simply won't work and it crashes as soon as I start an Aida64 Stress Test, which leads me to my next question: Will increasing the voltage to achieve 3.9GHz (I don't think my Gammaxx 400 cooler will cool it at 4.00GHz) be worth it? Also, would increased voltage noticeably reduce the CPU's lifespan?

 

Many thanks, Bruno.

this is the same for the r5 1600

 

as far as voltage goes, you shouldnt need to up dram voltage the xmp profile will do what it needs

 

on the cpu anything under 1.4 is technocally safe but stick under 1.375 for 24/7 use

I personally like to use HWMonitor to monitor my temps, and then use Prime95 to stress my CPU.

I also use HWMonitor. I have a screenshot of the max voltage it ran at during the 1-hour stress test. I'm sure it was about 1.27 something, 1.276 maybe. I will try Prime95 later tonight. Thanks

If your temps are good I would start to creep that voltage up, you may have some good silicon, unless you wanna run really cool and quiet.

Thanks a lot for the input. I will see if I can push it to 3.9 with a slight voltage increase so that the CPU cooler can handle it. I would need something more powerful for 4.0GHz, which I don't think would be worth to spend the extra cash for a 100MHz boost.

the stock cooler can handle at least 1.35v for the most part
