What's a good, safe RAM voltage for Ryzen?
I'm not sure anymore about the right voltage for my Ryzen 1st gen. My RAM works great at 3333mhz with 1.4v and has been that way for months, yet I can't resist pushing it higher. I tested 1.43v and 3466mhz, which made the computer boot up fine but failed the benchmarks. The specs are all in the top spoiler in my sig.
well u should go with memtest, that way ull see how many errors u get, if changes are improving it or making it worse as far as your timings go... tWR should be 10 or 12 tRTP should be from half tWR up to 12 (if twr its 12 then min is 6) your twr is 26 atm (which is slow for your refresh) another inconsistency is tRFC 443 while tRC is 80 tRFC is multiple of your tRC (from 6 up to 8) so if we say tRFC is 443, then tRC can be within 55 ~ 74 range tCWL should be same as tCL
Well, OCed ram usually won't hit more than 1.35 volts. I guess you'll make those DIMMs last shorter if you push them to 1.4 or higher. As proven in some Tom's articles recently, the drop from 3200mhz up to 3466 or even higher is usually just a tiny bit of a percentage. Sometimes there are no real gains at all, and other times those small gains show up mostly in computer scores and maybe a little more frames per second in games. I'd stick with lower speeds and the lowest voltage you can handle. Also make timing as tight as possible.
It all depends on which RAM chips are in your modules. Some of them can handle higher voltage, even if they need it to run faster. Samsung b-die is known for going really high, like up to 1.5 volts. But other types might get unstable at those levels. As a general rule, most chips work best up to about 1.4 or 1.45 volts. HWUnboxed has some great tools and videos on how to figure out which ones you have and what settings to use: View: https://www.youtube.com/watch?v=KOqhyVNPhaM&t=12s
I have some RAM sticks from Samsung that say 3200MHz, C16, but the voltage is listed as 1.35V. Since I'm keeping a lifetime warranty on them, I don't really care about how long they last. My main worry is making sure my CPU's memory controller (IMC) doesn't break because of high voltage or bad timing.
Have you tried turning on XMP before raising the voltage? I wouldn't push above 1.4 volts just because the board might take it or affect other components. Always stay careful when overclocking voltages.
Lots of people are running 1.45+ volt b-die chips on Ryzen 1000 models. If your current setup is working fine at around 1.35 - 1.40 volts, you probably shouldn't stress too much about staying in that lower range. Just make sure the VSoC (which sits right next to the IMC) doesn't get too hot or stressed out, since high voltages there are more likely to cause it to fail over time. b-die chips usually handle voltage scaling a little worse than regular e-die chips, so checking those memory voltage settings might help you avoid problems down the road.
