Hi All,

I am new to overclocking and have just finished my first build but I am having significantly lower results on overclocking my Ryzen 3600 (non X) than I was expecting.

Just using simple OC methods I am only able to get a stable system at 4050MHz at VCore 1.3250V and SoCV 1.1V. I am able to get stable at 4.1GHz if I push to a minimum of 1.4V VCore which is way too high for the chip (as is my understanding). Anything higher and I cannot boot into Windows.

What would be limiting my chip to 4.05X multiplier? I thought I would at least get 4.2GHz with around 1.33V VCore.

I am using:

MSI B450 Gaming Plus Max Mobo
Corsair Vengeance 16Gb 3600Mhz (XAmp on, Profile 1 or 2 both work fine) @ 18 18 18 38
Deep Cool GammaXX BK CPU Cooler.

At 4.05GHz under load I am getting Core Temps of maximum: 72^C and idles around 35^C.

I am sure it is something really obvious I am missing?
 
I would do my basic overclocking with RAM speeds at stock. Traditionally there's a trade-off between max CPU and max RAM speeds, although I don't know how much this happens on Ryzen.

Generally Ryzen 3000 manages its own speeds pretty well and you won't squeeze much more out of a chip with manual overclocking.

Hi Benski,

The RAM is 3600MHz RAM so I am only using XAmp to set it to its correct freq. The chip does brilliantly at stock and turbo's one to two cores to 4.2GHz under load, AMDs load management is really good in that respect. However I was keen to push it if at all possible. Not being able to boot into windows at 4.2GHz all cores under any voltage is really confusing me, especially as my cooling seems adequate.

While that is the RAM's "correct" frequency that just means that it is deemed to be stable at that speed. It's still overclocked RAM as far as the CPU is concerned and can limit maximum CPU overclock. Like I say, I don't know how interactive clock speeds are these days as I haven't overclocked my 2600 at all :)

It does seem like the consensus is that there isn't much to gain with the 3600. Which is good for performance but takes the fun out of buying nice parts. 4.2GHz sounds like the general limit but not sure whether that is all cores.
 
All I can get is 300 more points in 3d mark cpu tests for a core overclock to 4.4 GHz but get over 1000 points for 3800 RAM speed and tight timing. Also 1.4 voltages on the DRAM I have been told is completely safe. That an IF of 1900 is safe if stable. To keep SoC 1.1 voltages or lower.
 
Ok so turns out sorting out my RAM timings allowed me to overclock more reliably on my CPU.

I imported a report from Thaiphoon into DRAM Calculator For Ryzen and input the all of the settings for that into my bios, instead of using A-XMP profiles.

This immediately gave me better benchmarks on my RAM (obviously) but i thought I'd retry overclocking my CPU which was far more stable to higher overclocks. I was able to boot into Windows up to 4.25GHz at 1.33V VCore but Cinebench crashed out over 4.15GHz with a Max Temp of 82^C. Maybe increasing VCore would allow me to keep going but 1.33V seems like the limit that is safe from my research so far.

My final stable overclocks were:

DRAM A-XMP 3600MHz 18-22-22-42 64 => Manual 3600MHz 14-18-14-32 56, 1:1 with IF @ 1800MHz
CPU Stock > 4150MHz All Core 1.33V VCore
