I been messing around with my new amd ryzen 3900x for about a day loving it been a intel guy for the last 20 years. One thing im confused on which voltages do i need to worry about in hwinfo i see core 0-11 vids then on down CPU core voltage (SVI1 TFN). I decided to install AISuite3 and give its TPU overclock a try and to my suprise it might of found the stable settings for 4.4ghz testing the system with realbench now 76 mins stable so far. Any tips to help out a new amd overclocker out i tried PBO but it was using so much vcore and negative offset didn't seem to work very well and i was only getting up to 4500 on a single core and at full load 4119 i have been trying quite a few things.

So far this chip is 3hrs realtemp stable 2 hrs aida64 2hrs cinebench20 tossing linpack 64 at it now its using around 1.27 to 1.28 turned TPU clock off and did manual voltages cause TPU was causing my ssds to slow way down for some reason.

Can you go any higher on your RAM speed to bring your fabric clock up at all? Id say Minimum ram speed is 3600.
 
na my ram wont go past 3266.

I downgraded my bios on my board to 1 before newest and my ram got in windows at 3600 still need to see if its stable but i never was able to do that on the newest bios.

cool will have to read thru that stuff got memory at 3600 on 17 19 19 with 1.4 volts error testing it now.
 
Dropped back to 3200 for now 3600 seems out of reach every 2-3 hrs a program would stop working i pushed 1.425 to the ram could pass 3-4hrs of ram testing but random programs crashed might give 3400 a try now.
 
What are you cooling it with? Best way to get a head start on 3900X clocks is a good cooler, it seems.
 
420 rad and a 360 with a ek strike its never hit 80c no matter what i throw at it most of the time its in upper 50s to lower mid 60s.
got 3600 4hr stable in karhuso ramtest at 18 19 19 with 1.35 so upped it to 1.37 these chips dont like very high voltage im finding they are low end samsung bdies
