Ryzen 1700 overclock woes

[adrichardson81]

Hi all

I've been trying to overclock my 1700 for a couple of days, with limited success. Software overclocking (Ryzen Master and Asrock A-Tuning) works, but I'm not happy with it as a long term solution.

I tried traditional multiplier overclocking in the bios (dialled in 3900, 1.4 vcore, 1.4 memory, 1.1 soc), but end up stuck at 1.55ghz in the bios. I tried offset voltages and even pstate0 overclocking with the same problem. It looks like touching vcore with PState1 enabled is the route cause.

I've thought I managed to get around it by manually entering Pstate2 settings that I saw online. The OC stuck after a reboot (tested fine for 1.5 hours in Aida64), but after hitting dire performance in Witcher 3, I noticed that it was back down to 1.55ghz

Am I doing something stupid? So far the only way to get my 1700 to overclock is to disable cool and quiet and everything except Pstate0, which coming form a 4700k feels like going back in time 10 years!

Quick update - it looks like the 1.55ghz bug kicks in every time I shut down and restart, even with Pstate1 disabled. I'm at a total loss here - clearly something isn't working as intended here. Is it refund time?

It's a BIOS bug. Are you changing voltages in the Pstates? If so, don't. Set the multi's and then use the voltage offset from the main cpu overclocking screen instead. Other option is just do plain multiplier and fixed Vcore instead, the actual power usage compared to pstate OC isn't very different.

Thanks - 8pack sorted it in the end. If I manually set a voltage and CPU clock, then add an offset, it works fine. As far as I can tell, this rules out pstate overclocking on my mobo, as you can't change the voltage and the offset doesn't seem to kick in.
