Ryzen 1700 Throttling

[Huginn231]

Good evening,

I've been trying to overclock my Ryzen 1700 and have been getting some odd results. At 3.8ghz @ 1.3v it can sporadically throttle performance to 1.5ghz. I'm using a Corsair Hydro H105 cooler and I've never seen a temperature higher than about 50degC, and generally it's sat happy at about 30-40degC.

I have tried pushing it up to 4.0ghz @ 1.35v and this seems to prompt the throttling. I've set Windows power settings to high, as was suggested on another forum.

Just wondering if anyone can explain the sporadic throttling, and / or what I should do about it?

Complete newbie to overclocking.

I appreciate that it might lower CPU speeds when not in use, but this is curtailing by >50% and it doesn't seem to increase once the CPU is in use - for example in bench tests.

OK I'll reset all those to default and see what happens.

Ok thank you both - I've reset all those settings to default. Dialled the whole thing back to 3.4ghz @ 1.28v.

Seems happy enough running Prime95 at the moment. Temperatures are stable at 50degC.

I'll look to leave all those settings the same and try to slowly bring up ghz/voltage tomorrow and see if it avoids this problem.
