Ryzen Overclock issue.

[MorrisVentus]

Hello community.

I have some questions to ask.

 

This is my current setup:

https://pcpartpicker.com/list/RbK6zM

 

I currently have Ryzen 1700 at 3.9 with 1.368 volts, stable.

Ram was stable at 3200 mhz with 14 14 14 14 34 timing with XMP 2

 

But the story is, I purchased CPU mobo and ram as a set, because the seller claimed he could get 4.0 ghz with 1.3875 volts, with NB at 1.1 stable with water cooling.

 

He claimed to have done prime 95 for an hour.

 

But when I purchased it and tried it my self, it was different story.

 

Computer did boot up at 4.0 ghz with 1.3875 volts. But whenever I do Cinebench, it would instacrash.

I pulled voltages all the way to 1.4 volts, with LLC level 2. It did one cinebench and crashed.

 

During this process, I realized that the temperature read up to 77 and then crashed right away.

 

I assumed it would be thermal issues, so I re applied thermal paste, and re mounted Dark Rock Pro 3 (which was hell of work to do alone).

 

No difference.

 

So I went back to 3.9 ghz, starting with 1.35 volts. Crashed cinebench.

At 1.368 with llc level 2, it was stable, so I did real bench and prime95. Stable.

 

But during stress test, temps went up to 86, but non of the cores failed.

 

So this would eliminate the thermal issues.

 

 

Next question would be the power supply.

 

I purchased new EVGA 650 W g2 for 60 bucks somehow, because it was one of the tier 1 PSU recommended here.

 

But then I do not have other PSU to try this out.

 

 

Other things I tried were changing Bios version.

When contacting the seller, he said he achieved this with Bios version 13.

Current bios version when I received the mobo was at v15.

 

I flashed to v13, but didn't do any trick.

I also tried v17, which uses 1.0.0.6 AGESA, which I did hear that AGESA 1.0.0.4 does affect CPU overclocking performance, 

but this version did not let me have 3200 mhz, and got stuck at 2400 mhz for some reason. (manual timing input or XMP profile did not work)

 

 

So what do you think the problem would be?

I know 4.0 ghz only sounds nice, and will cost more bills and thermals.

 

But I would like to be sure to have what I purchased for.

It is good lottery chip, but yeah.

 

What would be the reason for me not to able to achieve that 4.0 that seller insists to claim he did?

I did contact him, and he was kind enough to help me out, but we did not have any luck.

 

 

 

Any suggestions or solutions?

 

Thank you in advance.

I would say you did pretty good with the 3.9 ghz and call it a day. Not trying to say the 4.0 Ghz doesn't matter but it seems like it just doesn't want to do it for you. As far as power goes the vrm and power phases is what should keep it stable and it's a nice psu so it shouldn't be the problem. Maybe they didn't run cinebench and we're fine at 4.0 with running prime 95.

Yeah.. But was just curious if it was possible.

 

I tried Prime95, but crashed into black screen at 1.4125. So didn't even bother to do higher voltages.

But yeah. I was wondering that cpu mobo ram are all the same, and only variable I could think of were cooling (air vs AIO), and power supply. So yeah.

Just be glad that you can get 3,9GHz

I can't even get 3,9GHz on 1,45V from my Ryzen 1700.

sorry to hear that.

Yeah. Just wanted to see if what the seller claimed was right or not, since I did buy binned cpu.

Even if you and your friends had 5 of the same motherboard, with the single Ryzen CPU, you'd still get different results and voltages, it's not a copy/paste and it'll work scenario.
