Thinking About Attempting 4.1 GHz (Ryzen)

[Emberstone]

Hey there, folks. I've got an R5-1600X overclocked to 4.0 GHz on 1.337v right now, and I've been thinking about attempting 4.1 GHz, but I'm worried about chip lifespan. I'll preface this by saying that I haven't tried going past 4.0 GHz yet, but I assume the chip lifespan should be fine as long as temperatures look good (I shoot for below 80 C), and I don't start pushing past 1.4v?

 

I know that voltage is probably the biggest factor in chip death, but can running it at 4.1 GHz 24/7 (since Ryzen doesn't downclock when you OC) noticeably affect lifespan?

Well the highest voltage you should run on Ryzen is 1.425V so if you can do 4.1GHz on that then go ahead as long as you can keep it cool(bellow 90C)

If that is stable then that's really really low. There is a point when voltage required gains exponentially but it looks like you have the headroom for 4.1GHz. Give it 1.4V to start. Then if stable back it down, unstable increase it. Max limit of 1.42-1.45 (different sources say different things) use the lower limit to be safe.

Follow guide in my sig if you want Ryzen to do this.

I actually read the guide a long time ago. My motherboard doesn't support the options required, unfortunately.

 

And yes, it is indeed stable at 1.337v. It doesn't crash in Prime95 LargeFFT or Aida64 and has also been running like this for over a month with no issues

I'm going to attempt 4.1 GHz at 1.35v first. So far, it has booted into Windows like that.

I highly highly doubt that. If that passes then congrats on winning the silicon lottery  Onward to 4.2  report back

Black screen as soon as I started Cinebench. Lol. Attempting 1.375v.

 

If this doesn't work, I'm gunna go ahead and stick to 4.0 at 1.337v. Temperatures and performance are pretty sexy with that setup. Dont want to push suuuuper hard since I like having a quiet system as well.

 

Edit: 1.375v didn't cut it. Womp womp. Oh well. 4.0 GHz and 1.337v is nothing to sneeze at either.

Any overclock that exceeds the stock voltages will decrease lifespan, but even at 1.4 volts, you should have to upgrade it before it dies on you, so I believe you'll be okay with it at that speed.

I run my processor at 1.425v, 3.8ghz, I did not get a very good chip, but my AIO Kraken x62 cooler keeps it below 63C under full load, so I haven't run into any issues, and probably won't.

My R7 1700 requires 1.325V for 3.8Ghz and 1.425V for 3.9Ghz. When Ryzen reaches it's limit the voltage requirement jumps significantly. I wouldn't be surprised if you need 1.425-1.475V for 4.1Ghz on your chip. You would need a serious cooling system to handle that though, and the power draw would not be worth the relatively tiny clock improvement.

Go 1.4 then call it quits. Remember what manufacturers say is conservative so if you are below their conservative voltages you are absolutely fine. You will do no harm running 1.4 daily. Also you may be crashing because of V droop. Give V core some load line calibration if you haven't already

Yeah I think everyones wall is in different places but its definitely there. up to 4.0 my 1700 is linear but 4.1 is impossible without exceeding voltage guide lines.

I'll try with LLC set to Medium first as I don't have anything more specific than Regular, Medium, High, or Extreme.

 

Edit: still a no-go. I think I hit my wall.

 

With Medium LLC, it stuck to target voltage for the few seconds it was running Cinebench before crashing.

Screw guidelines, I don't plan on using the CPU for 10-20 years. I budget for my systems to be decommissioned after 3 years and I am just sick of still having working 7+ year old systems lying around, they should have died a long time ago.

I'm just a college student who doesn't know when he can afford his next system, so safe guidelines are my bible ATM. Lol.

Careful... Someone on this forum ran 1.5V+ and their Ryzen died within a month... When I say you can exceed the conservative estimates I mean you can go <1.5V.

its completely safe to put this on extreme btw. Basically when the processor is under full load the voltage sags. If it drops below the voltage required then it will crash. LLC increases the voltage when underload to maintain the voltage you set in the BIOS. IDK why they have given it dumb names like extreme but there is nothing extreme or dangerous about using it. Mine are called "level 1-5" I have it on level 5

on my 1800x i can reach 4.0 fine but at 1.4xv under load, with temps being 40c ish idle and 75-80c under load

at 3.9ghz with idle voltage of 1.419v i get idle temps of 25-30c and load temps(1.35v ish under 100% load) of 55-60c

I hope they were using phase-change cooling at that voltage. It would have been quite a fun science experiment while it lasted.

I figured going with High or Extreme on my mobo will probably increase voltage under load since Medium neutralized vdroop and left my voltage near-constant.

 

Since I can't afford to replace my system if I end up unlucky, I don't want to run at or past 1.4 since that's quickly encroaching on AMD's 1.425v limit.

 

In light of what I've learned this evening, I'll stick to the overclock I achieved last month. Thanks for the help and advice! Gives me more to tweak when I upgrade in the future.

If using Prime95 don't only run large FFT. That intentionally uses large data sets which will also exercise cache, memory controller and ram too, which may limit and not stress the cores as much. For a more heavy core stress also do some small FFT. Further note Ryzen detection support was only added in version 29. That will use AVX code. If using 28.x it doesn't recognise Ryzen and will use older AMD code.

Wat.

 

That's a high idle and a low load
