R5 3600 OC.

[Dugbuzzz]

Hello, pretty new to OC'ing, and wanted to give it a go, so I figured I would try it out on Ryzen Master. Right now I have all cores around 4.1GHZ, but my voltage is at like 1.35, and I have heard that you can get it quite a lot lower than that, what would you guys recommend I set it to?

Be very careful with static voltage on Ryzen CPUs! 1.35v sounds quite high.

I have heard that the max safe static voltage is 1.325v, but there really isn't any evidence to back this besides a few Reddit posts. 

 

Don't panic, you likely haven't hurt your CPU by running that voltage, just do a bit of research before going any higher. Ill edit this with more info, just want to let you know now before you go any higher.

you have to experiment.

 

Also, BIOS overclocking is more stable than Ryzen master overclocking.

Alright, thanks, like I said I had no idea they could go so low, I saw it running at like 1.4v sometimes with everything auto, so I assumed it was okay, processor is happy and cool now running at around 1.32

4.2Ghz 1.325V is what I run my 3600 at, I would recommend the same.

Ok sweet, I don't know why I didn't do this sooner, temps are cooler than before and it's running faster. I'll try those settings out, my cooler isn't super good so I might not quite get there.

Have you tried going lower on voltage?

Question - maybe a stupid one - but I run the 3600 myself. It overckocks itself with PBO very stable and reasonable and boosts itself almost to the max one can expect from manual OC. SO why bothering with OC with this CPU? The gains are minimal compared to the increase in heat and power consumption. IMHO - not worth OC'ing this CPU. Only lowering the VCORE could be a valid option as most boards set this too high at Stock.

 

With PBO enabled and reasonabme VCORE settings, this CPU is really fast and clocks really well for a temperature based auto OC.

The voltage was originally my only reason for doing it, but no matter what I did, PBO, Auto OC, they both topped out a 3.9ghz. And the chip was at 65C, max. Lowering the voltage myself and and manually doing it seems to be working great for right now, it's cool, quiet, and faster than when I started.

 

EDIT : And it's fun.

Well this is called silicon lottery. My 3600, running on a first gen B350-F, runs also at 3,9 all core at STOCK!!!! settings with a max of 1,29 Volts and boosts to 4,2. If I manually OC it to 4,1 all core it is stable but WAY hotter and not reasonable faster to justify the OC - at 4,2 all core it gets unstable....I think the non X models are the "not so good" silicons that tend to OC not so well...ok in my case the fist gen board could be a factor as well....but..well .7 percent more performance it not worth the amount of heat it produces....

 

Well "fun" ok - if it's fun for you, it's fine.  I just need a working system and the 3600 is pretty much at its limits with most stock/PBO settings - WAY different than the 1st gen Ryzen CPUs where simple OC to the boost Clocks all core made pretty much sense.

 

I see no performance gain when lowering the voltage (with an offset of course) - I just see slightly lower temps.

Yep, too much lower just instantly crashes during Cinebench R20.

[Miccellomann]

How low did you go? Did you use an offset? Which board do you use anyways?

I started at 1.20V and worked my way up by 0.05V until it stopped crashing, I have an MSI Gaming Pro Carbon X470 mobo (Overkill, I know ).

Not overkill - just not a good overclocker board in that price range....decent but not the best out there. Solid midrange board.

Silicon lottery is right. Motherboard might be part of it too. I can do 4.2 all core at 1.2V. The whole point of lower voltage is to get lower temps though, by using less power. Gaming temps are basically nothing anyway though, compared to F@H or benchmarks.

 

Speaking of silicon lottery, my wife and I have identical 5700xt's, she had a weird glitch last night so I played with her card this morning. I can get 2150mhz @ 1.175V and memory at 1875mhz. Mine crashes at any voltage under max if clocks go above 1950 or so and my memory can't go over 1850... And her's undervolted really well at stock clocks. Haven't stability tested anything yet, but eesh.

@ Radeon 5700XT - let it run stuck - or you run into problems. Card handles itself pretty well. Those cards have no real OC potential....no need to undervolt those cards if you have one of the good aftermarket models.
