Ryzen 2700 EDC Limit, new motherboard or fix?

[SammWolf]

So I just upgraded from a Ryzen 1600 to a 2700 and my cpu is capped at 3.4ghz. I have an MSI B350M Mortar Arctic motherboard and Ryzen master says my EDC is 100% of 90A out of 168A. Why am I only able to get 90 out of the 168? Do I need a new motherboard or is there something I'm doing wrong. I don't really care about overclocking but I would the auto boost to have more headroom. If I disable 2 cores my cpu jumps to 3.725ghz. If I do need a new motherboard are there any cheapish recommendations as I don't really have a crazy amount to spend and my case is m-atx so an atx board would require a case upgrade too.

You need to change Minimum Processor State to anything below 50% on whichever Windows Power Plan you'd like to use.  I use 20% with the Ultimate Performance plan.  And with a 2700X you can change that value in BIOS or right there in Ryzen Master by selecting Precision Boost Overdrive after selecting a Profile tab at the bottom.  I don't know if it's a feature that's enabled for a 2700, however.

I've got it set to 20% min power state on the Ryzen balanced power plan at the moment. Precision boost overdrive is available on this processor but that's only on gen 2 boards mine is only a B350 board. So I'm not able to increase the EDC there unfortunately.

Can you access the Precision Boost Overdrive settings in Ryzen Master?

I can't because first gen Ryzen boards don't support PBO only second gen ones do. The CPU supports it but the motherboard doesn't.

Ahhh I thought you were talking about the BIOS.  So if that's the case then a new mobo could get you some more performance, but I don't know if it would be worth the cost to you.

Hmm, well I guess I'll just hold off on a new board for now as long as the 3.4ghz doesn't effect my games and stuff. Thanks for trying.

Wait, 3.4GHz is the fastest you get on all core workloads?  Perhaps you should just overclock that 2700.  What is the fastest single core speed you see?

If I run cinabench single core test all the cores stay at 3.4 and vary rarely max out at 3.5. but 99% of the time they are all at 3.4. I thought the other cores would slow down so one of them could use the extra power but that doesn't seem to be happening.

Edit: I'm not sure I could overclock it beyound 3.4 anyway because I think the motherboards VRM might be limiting it. but I haven't tried yet.

Hmmmm, that's doesn't seem right at all.  Are you certain Minimum Processor State is still to what you set it to?  Sometimes it will set itself to 100%, but I haven't figured out why it does that.  

 

Edit:  

And have you changed any voltages in your BIOS?

I checked and it had set itself to high performance with 100% min. I changed it back to 20% and ran the test again and am still getting all cores sitting at 3.4 during the single core test.

I'm messing with the voltage in Ryzen master now and I have it at 3.5 but I can no longer see the EDC which makes me worry it will burn out or something?

I wouldn't mess with any of the voltages in Ryzen Master.  I was asking to see if you set a static voltage for your VCORE.  If you set a static voltage then your CPU will go into overclock mode which prevents it from going through its power states and limits speeds.

And when was the last time you updated your BIOS?

The last bios update I did was about a month ago. My vcore is on auto and everything else is also set to auto.

I would see what a manual overclock would do for you then.  If your CPU only clocks itself to 3.4GHz then seeing if you can get a manual overclock close to 4.0GHz would be something I would try myself.

Okay, I'll give it a shot tomorrow when I get up, thanks.

I tried a lazy overclock with 1.35v and 3.7 because I figured it would have to work and would tell me if the cpu really can't go above 3.4 on this motherboard. It worked fine but the temps were too high for the stock cooler. although without knowing what the VRM temps are I'm a little worried about burning out whatever the EDC is by going above 3.4. I'm going to look into a higher end B450 motherboard and maybe a BeQuiet Darkrock 4 pro when I can afford it. I'm not sure I really need X470.
