I hope you mean 1.325 volts otherwise that chip will be fried..


I believe anything above 1.45 is the "danger zone". My chip stays below 75 degrees when running prime95 and doesn't break 60 degrees when running PUBG.?

If I lose a year or two out of the lifespan of my chip, I won't mind, especially since I'll probably be upgrading to the next Ryzen chips next year if the IPC is better.


Totally up to you, however you shouldn't need to go that high for a stable 3.8ghz OC from what I've seen. Mostly all chips can hit 3.8-3.9 in the 1.35 range no problem. Also, they replied to my ticket about the UEFI overclocking so I'll keep y'all posted if anything comes of it.

I agree that the VCore should be as low as possible for multiple reasons, and ~1.35V is usually enough for 3.7 - 3.9GHz depending on the CPU.

But apparently you did not notice the Auto/default VCore and VIDs. Using a 1700X with an ASRock X370 board, the Auto/default VCore was ~1.45V, with the core VIDs at 1.5V. VIDs are programmed into the processor by the manufacture, so should not allow a destructive VCore to be applied to the processor. Actually, the maximum VID defines the VCore limit that may be applied. Again, way more than necessary, but apparently not outside of AMD's design.

From ASRock

"Its able to reach 3900 with voltage 1.36. Also test with 1.34v @ 3900 still working.
However, due to power design the max CPU voltage could reach 1.36 regardless or set at 1.37 or 1.38, the BIOS H/W monitor will shown 1.36 but CPU-Z might shown 1.375
Please see attached screenshot.
Please be advice, the overclocking is not always guaranteed, its depends on adopted components and the whole system configuration."

To give context- he said he got the OC to 3.4ghz at 1.35v or something. ASked if he could try and push more closer to where we are. That is his latest response. Also he is using UEFI P3.2, and RAM is all at 2133

Alright so for those who are interested- bios 3.2 works good. OC'd to 3.8 @ 1.35v, and the memory work at 2666 just by turning on XMP. Lowered timings to 14-14-14-14-35 and left the voltage at the 1.2 auto and it works like a dream

Will try on the weekend, thanks for the update!

Do you have any issues on 3.2?

EDIT: Unfortunately, it doesn't work. This sucks, rather my luck is just cringe worthy. Time to get a new motherboard...sigh

I just tried PState0 OC'ing with the BIOS 3.0, and it doesn't work. I set the VID to 20 (1.35v) or 1E (1.36v) and the FID to 99 (3825) and had a lot of trouble booting. When I did, HWiNFO64 told me my clock was at 2800 and my vcore was around 1.375-1.385.

I tried with lower values, and needless to say, it didn't work for me.

I'm inclined to believe this board is just garbage. This was my first ASRock board, and I'm thoroughly disappointed if it won't even let me Save & Exit with the settings. It's stable in Ryzen Master, so it's not the chip being unable to handle the OC. I can't even boot with lower values!

If anything this experience has taught me not to buy a budget board, and just go full out on the best board because this is absolutely annoying.


I get this same bug.

Your overclock doesn't stay stuck at 1.35V?

UPDATE: Updated to BIOS P4.60, and it fixed all my problems.

R5-1600 Stable at 3825MHz @ 1.35625v and was able to get my Coasair Vengeance LED 2 x 8GB ram stable at 2933MHz with timings 16-17-17-17-35 @ 1.35v with XMP.

Great BIOS all-in-all. Finally happy.
