Overclocking the 1600

[Spiffo]

Hi. Thanks to this community's recommendations, I recently upgraded to a Ryzen 1600 with the intention of overclocking to achieve performance closer to the 1600X. However, I am a novice overclocker and have some questions/concerns I was hoping you guys could help me with.

 

First of all, what I've achieved so far is 3.8 GHz (on stock cooler) at 1.38V according to CPU-Z. I have a number of concerns:

1) This seems a high on the voltage compared to the results I've seen from others. Is there a simple explanation for why my chip needs so much more voltage to finish a Cinebench at 3.8GHz? Or is it just silicon lottery

2) CPU-Z, HWMonitor, and Ryzen Master all seem to be reporting different values for the voltage. CPU-Z shows 1.38V as I said, while HWMonitor reports 1.55(?!), and Ryzen Master reports 1.2375V on CPU core and 0.9V on VDDCR SOC

3) I have no idea what VDDCR SOC voltage is or what it should be. Please tell me all about this.

4) The voltage adjustment on my bios (Gigabyte GA-AB350M-D3H) is a little clunky (see attachment) in that it only lets me do voltage offset rather than setting the actual value. Right now I have it set to +0.12V on Dynamic Vcore and "Auto" on Dynamic Vcore SOC (still have no idea what this is), not what it shows in the picture. What do I do with this?

 

any responses to any of my questions from experienced overclockers would be greatly appreciated.

Cpu z should be correct

ryzem master is the stock voltage which is weierd and doesn't show the oc voltage for the 1600

i got mine to 3.9 at 1.35 r15 and Aida 64 stable at the same time 

and 4.0 at 1.45 v but I run 3.9 

 

how are your temps at 3.8 with stock cooler ?

temps were very good - never reached the 70s

 

I should note that I didn't try going above 3.8 because I'm still really uncomfortable with this voltage. I still don't know how much headroom I have left.

Amd say 1.45 is the max with a decent cooler

Thanks. That is good to hear, though I want this chip to last me a very long time (4 years+) and I imagine keeping the voltage low can help with that.

 

Any idea on what the distinction between core voltage and core SOC voltage is?

Soc don't go over 1.2 as it's the onboard pc on the chip essentially but there no need to touch that really
