Returning to AMD on a Ryzen APU Part 2: Overclocking the Ryzen 5 3400G Through PBO (Results and Rant)

So you have a brand new (lol it's been out for almost 4 months) Ryzen 5 3400G. It's an unlocked chip and you really want to push it to the limit. What to do?
  1. Watch this video about AMD Precision Boost Overdrive
  2. Download Ryzen Master
  3. Max out all the automatic values 
  4. Watch your computer crash and burn Watch your temperatures! You might not be comfortable with the VSOC MOS going upwards to 90c.
  5. If you're experiencing stability issues, I suggest increasing the overdrive by the 10s.
 Yeah I just maxed the boost overdrive for GPU clock to 200mhz, while I only added 100mhz to the CPU clock. Also I clocked the memory up to 1600mhz from the base 1333mhz.


Next up are some benchmarks? Dunno just snapped some screens while running tests/games. You can view some actual gameplay benchmarks here:

My system specs:
CPU: AMD Ryzen 53400G with Vega 11 Graphics
Motherboard: Gigabyte Aorus B450i PRO WIFI 
Memory: Kingston HyperX Fury 2666mhz DDR4 (2x4gb) 
Boot Drive: Team Group 240gb SATA3 M.2
Storage 1: Western Digital Green 120gb SATA3 SSD  
Case: InWin Chopin SFF Case with 150W +80 Bronze PSU

Black Desert Online running on the "Really Toasty" profile.

Monster Hunter Online is a date game but it has a really useful stand-alone benchmark. The stock 3400G scored 4530 points.

This result is from applying the 200mhz on both CPU and GPU clocks.

Overclocking the memory to 1600mhz seems worth it though. If only I had more power. My computer's 150w bronze power supply is starting to feel like a real bottleneck.

Cinebench R15

I'll probably do a more "professional" Ryzen 5 3400G benchmark soon but you know, there's already lots of those online. Heh. Can't wait to upgrade this build (in a better case, with more power, and finally better cooling).
