I will increase voltage if it happens again, but it doesn't happen very often.

The thing is Threadripper has been speed binned by AMD. Apparently only the top 5% of dies make it to retail (could be higher for the 1950x), so you have a much higher chance of a golden sample and the CPU being fine at lower voltage. I can't get the motherboard to post at 4.2 GHz even at 1.35v though if that makes you happy. :P

well it cant be impossible ,as hes doing it

but it may be the reason its locking when transitioning out of sleep mode i would adjust it up myself and test it for a while maybe at least 1.3 volts

i can do 3.9 ghz at 1.3 volts with my 1700 but upped the voltage a little to rule out instability with higher clocked ram

i would agree with wardog the voltage does seem tobe on the low side

maybe its causing the intermitent issue from resuming from the sleep state to a lowish voltage ?

I tried 1.26v after reading about someone who got 4GHz @ 1.225v or so on a forum thread and it seemed stable after prime 95 testing. I then played a lot of games and it didn't crash then either.

The lockups after resuming are a very rare occurance, in fact I have only had one unrecoverable stutter after bringing the monitor out of standby and one black screen after logging a user out (the hard drive lights seemed to still be responding). I have owned the computer since Jan and must've entered standby mode hundreds of times. I realise those two lockups could be described as an anomaly, but in my experience they tend to repeat themselves eventually in computing, so I was wondering if it could be a motherboard firmware glitch.

I'm using the fast preset. The Extreme preset was disabled as an upcoming feature in the version of Ryzen Calculator I used to generate the memory settings.
