R7 1700 Overclocking help

[TRraven]

I have had my 1700 since launch and previously overclocked it to 3.9 then had to rma my mobo because my Ethernet jack went bad. Ever since I haven't be able to reclaim that clock speed. 

 

I would like to aim for 3.9 or 4ghz. 

 Currently running 3.8ghz @ 1.38v with 34 c idle around 60c on full load.

Running a cryo-rig r1 universal. Ram speed set to 3066.

My mobo is an asrock x370 killer sli/ac

 

I'm looking for a more advanced guide to get the best performance possible, not just tweaking core voltage and the multiplier, going in changing a few settings in the bios to achieve higher clocks since I've had this CPU for over a year  now.

Put a fan over the VRM so it has active cooling, what case and temperature does it run at?

If for some reason the other motherboard was blasting voltage the CPU may have just degraded.

Haha I was watching that video as I was clicking back to this tab, I have a Silverstone rv02 with 3x 180mm fans are the bottom for intake, 1x 140mm at the top for exhaust. Cpu idles at 30ish Celsius and 60 under full load on air

Outside of the active VRM cooling which shouldn't matter, I got nothing.

 

What were you stress testing with? Cinebench is likely good enough

im using cinebench for short testing because its a relatively short test, if it passes then i move on to blender, if blender doesn't fail then I go into the bios to find a lower voltage that it will pass both tests. Currently if i want to run higher than 3.8ghz here is what I have found, 3.9ghz @ 1.425 v passes cinebench and blender fails 95% of the way through with max temps at 67c. I can't seem to get anything higher than 3.8ghz stable

Blender is an AVX workload like Prime95 and is more stressful than cinebench I'm pretty sure

There may be an AVX offset in the bios that lowers the voltage for those workloads since they use more power as well, though it should lower clock with it to prevent crashing.

also to note my mobo has heatsinks on the vrm which should be enough cooling for them considering the airflow of my case

I have looked through and through my bios and ever since i got it I haven't found the llc  setting

Not all of them have it

[TRraven]

Yea i figured kinda bummed tho its an x370 and doesnt have llc

I found my old 3.9ghz preset i saved, 3.9ghz @ 1.43750 v ram 2933 max temp is 65c. AMD doesnt reccomend going higher than 1.35 for life span but says 1.45 is the recommended max. In regards to electronic desegregation does the voltage really matter if the temps are surprisingly low?

Voltage still kills, that's kind of pushing it for not much more performance unless it's just to run a benchmark or 2.

Love this video response, in regards to voltage still kills I stream on twitch while playing esport titles at 250+fps. So my cpu is constantly over 80% load. I was wanting to increase my clock speed to be able to sustain higher fps with lower dips in frames. Would it be safer to just go back to 3.8ghz?

[TRraven]

currently running 3.8ghz @ 1.35v is stable with cinebench and blender. Same for 3.9ghz @1.43750. The Difference in cinebench is 30 points consistently in multi-threaded performance.

im going to run aida 64 now for cpu and memory. Prob going to let it go for a couple hours or so. my ram kit is rated for 3000mhz do you think i should go for higher if its still stable at 3066mhz also im noticing Aida temps are off compared to ryzen master. by like 10c aida is at 45 ryzen master at 55

Having to maintain anything above 1.4v on Ryzen 7 first gen I consider high, but you are obviously cooling it and don't really mind.

 

Silicon lottery is everything, and not many Ryzen 7s really achieved a 3.8ghz+ overclock without having to hit 1.4v+

 

I know mine will not run 4ghz stable unless I run 1.45v, which is why I leave it at 3.9ghz. Even then, I've had issues with stability depending on the BIOS version I was running on my motherboard requiring me to manually set my settings again and cross my fingers that it'd boot (sometimes it would just not boot with my settings because it felt like it).

 

My biggest recommendation is making sure you are running the latest BIOS and really only run your memory at what it is supported to run at with Ryzen. I am running a Ryzen certified kit, so I don't worry about RAM frequency, but if you aren't, it really is a lottery. It's just how it is with Ryzen first gen.

@Jon Jon thank you, i think i should just stay @ 3.8ghz with 1.35v since i cant hit 3.9 anymore unless im at a high voltage. its not like im running 4.0 with 10-40% cpu usage either. I'm streaming the highest quality 720p with 250fps in game with an 60-70%+ on my cpu 15+ hours a day

A big reason why I went Ryzen 7 and OC'ed was because I was big into streaming and running Plex.

 

Now I primarily do some gaming and VR gaming with streaming on occasion, so I get you for sure .

 

Really, the pair of us should be paying attention to Zen 2 and considering if that is worth the upgrade if we need it, but I still fine the first generation to be plenty for these types of tasks.
