How far could I O/C a Ryzen 7 1700 at stock voltage?

[smilingcrow]

I like to keep power consumption low to make truly silent cooling easier so wondering how far I could push a 1700 at stock voltage whilst keeping low idle power consumption?
I'm thinking in terms of the maximum clock with all cores boosted.
I don't mind pushing the TDP above 65W so aiming to get as close to an 1800X at stock voltages.

The last time I tried this was probably with an Intel 2500K and I kept the voltages on stock and just upped the multiplier until it became unstable.
Is it that easy with Ryzen?

Which motherboard?

I found on the Pstate overclocking on the CH6, the voltage went down with the OC.

From Auto at stock of 1.35V to 1.21V at 3.6Ghz all cores.

I have tested this with 3.8GHz but cannot offhand recall the voltage, it was under auto volts though.

Thanks. I don't have one as I'm researching the basics in terms of over-clocking at this point.
If I take this route my budget would be around £100 - £130 so nothing too fancy.

all you can do is set it to auto and bump the core speed up and see what voltage you get. then manually set voltage till is doesn't work. If you are after a balance of speed to power usage, the further you push the cpu the higher to voltage you'll need.

Just buy a cheap B350 board. 3.7 should be doable on relatively low volts (<1.2v).

I'm not sure exactly why the people are suggesting you can't manually set the voltage. You definitely can.

For reference an 1800X is at stock doing 3.7 @ 1.225v.

From past experience with some boards Auto settings can actually over-volt and I had to use another setting (Stock!) to get it to run at stock settings.
With the AM4 platform if I leave it at Stock (not Auto possibly) and raise the multiplier by 1 or 2 will all the power saving settings still be in play?
So it will still idle at a much lower clock and voltage!

As per my original post I want to run it at stock voltage so have zero interest in increasing it.

Stock voltage should get you to 3.6 easy.

it is set to auto as stock.

3.6 should get 3.8 with minimal bump then it's diminishing returns

Mine does 3.7Ghz on 1.2v and is completely stable. Just set the multiplier and left it on auto.
