To ryzen 2600 owners: Degradation experience with Ryzen 2600

[LOST TALE]

Running 1.425mv and whilst 4.2 ghz might have been stable (unclear records but memory tells me so) with prime 95, and 4.125ghz surely was stable on a 8h P95 test 2 weeks ago. 4.125ghz appears to cause a game to crash. but lowering the last CCX's cores to 4.1ghz seems to resolve the problem.

4.2ghz was individually stable on each core, but not if run simultaneously. 

 

Maybe another 8h test at 4.125ghz is in order to detect possible degradation?

"I believe that Steve from Gamer's Nexus stated in a recent video that 1.42 volts is the maximum recommended CPU core voltage for Ryzen first-gen and 1.38 volts is the maximum recommended for Ryzen+."

ryzen 2600 is ryzen +? 

 

This cpu has been out for some time. What have you guys tried and what happened? I know the bios would use pretty high voltage in the past depending on the version.

 

Also, for gaming, is it better to run the max Ghz in total or is it worth sacrificing total Ghz to boost one CCx over the other?

Cpu usage is someitmes over 50% at 4.125 in the game so I don't think disabling one CCX is a good idea.

Yes, all non g ryzen chips are using Zen +. It is entirely possible that you have pushed too much through the transistors.

For Ryzen second gen the commonly accepted as safe voltage for a daily all-core overclock is 1.375V. You can run more than that, up to 1.45V for benchmarks only, but the CPU will degrade quite fast if you use that kind of voltage for 24/7 operation. Therefore, I recommend you dial back the overclock to something that is a bit more conservative and doesn't require Vcore voltage to be 1.425V. 

 

Regarding the CCX, don't disable one of them, that really wouldn't make much sense performance-wise. Many games today do leverage six or more cores.

Regarding the CCX, I was thinking about eliminating the inter-CCX latency

 Just one source, but there is an pro / semi-pro overclocker with 4x Ryzen 2700X, and his/her findings.

Quote

2700x sample 1 - 1.425v, max of 65c while gaming/daily tasks - saw degradation of around 100mhz at the same voltages within 3 months

 

2700x sample 2 - 1.4v, max of 60c while gaming/daily tasks - saw degradation in around 3 months and 2 weeks

 

2700x sample 3 - 1.385v, still around 60c while gaming/daily tasks, saw degradation in just shy of 4 months

 

2700x sample 4 - 1.375v, max of 58c - no degredation after just above 6 months now

I wonder if we have any new data since then.

You are probably not going to get an real answer what safe voltages are unless you hear it from AMD. I've push my 2700 to 1.34V for a few days straight a number of times. It still works, but I usually just leave it on auto or lock it at 3.8MGHz at times since it's no longer my main system. After 2 years I have noticed some problems depending on what I am doing.

Well with some experience, I noticed some things that would differ my experience to others, not all chips are equal.

 

So with performance enhancer enabled to lvl 3, puts all cores to 4.1ghz and 1.410v at load which I had used to base my testing on. 

These numbers running stock EDC, no increase on the power limit.

 

The degradation on these chips will be pretty instant at near 1.60v which I had experienced with a Ryzen 1200. 

 

The best thing to do is lean on belief of FIT voltage which you would run Prime95 large data and PBO enabled all other settings stock. Stay at or under that voltage, you should experience little or no degradation at all. 

 

For my 2700X, temps really played a super big role with lowering voltage at any given frequency. So with testing, 4000mhz at 1.180v but -30c idle and a max load temp of just under 20 running cinebench.

 

Not necessarily the voltage that degrades a chip but the current (amps) with high temps does the job and can be rather quickly.

Single core loads, 1.5v would be completely safe considering the temps will be relatively low and the current will also be low. But definitely not running 1.5v to make some achievements while these chips wall pretty hard at X frequency until you've gone below 0 far enough to jump that wall.

 

If I where to suggest a max voltage for all core loads on a Zen+ 2700X processor, it would be 1.410v max on any ambient or even sub ambient cooling.

 

This is only my experience and encourage you to take anything I've said with a little salt while your system and cooling will differ from ambient temps and VRMs and so forth.

I'm not sure about updated data for Ryzen 2000-series, but I think I remember finding something about Ryzen 3000-series.

Ryzen 3000-series is EVEN lower voltage, it's like 1.325V or something.

 

As @ShrimpBrime mentioned, short-term or single-core load, higher voltage it okay.

For long-term or all-core loads, you want to a lower voltage.

Also the point to note, it's not the voltage, but the current running through the CPU that degrades it over time.

Voltage goes up, Current goes up.
