Off the top of my head.....

1/ In Bios under OC Tweaker set CPU Frequency and Voltage Change to manual but DON"T change anything!...just look and write down what your default vcore reads. Once done set this option CPU Frequency and Voltage Change back to auto.

For my 1700 it is 1.18750V

For my 1800X it is 1.3500V

2/ Scroll down to Voltage Configuration section and for CPU Core Voltage set OFFSET MODE (you will need to know your max frequency of your overclock and what volts are required to achieve that prior to doing all this) set your OFFSET value; example my 1700 needs 1.34375V for 3925MHz with LLC Level 1

So I need to set in OFFSET MODE an OFFSET value of 15625......this means that .15625mv is set on top of my default vcore of 1.18750v to give me 1.34375 volts.....got it smile.gif AND set your desired level of LLC which for me is Level - 1

You will need to work out your own values for your own cpu's but it's not that difficult...just remember that each 10000mv in offset = 0.1v to vcore.

3/ Go to Advanced tab - AMD CBS - ZEN Common Options - Custom Core Pstates. Here you only want to change Custon Pstate 0, change it to custom and change the Pstate0 FID only!!!!....so for 3925 I set 9d.

That is it....F10 and exit!

Now you will have both core and voltage downclocking in windows at idle and your oc will be your max core clocks when loaded. smile.gif


Summarize

1/ set OFFSET Value and LLC level
2/ ONLY! Change FID value only in Pstate 0

3/ Hit F10 your done.


REMEMBER do it all at your own risk.....biggrin.gif

Thank you so much. I understand better now. Its working for me with 3.925 and 3.825 overclock.

Basically your Max volt you want 1.34375v - CPU default frequency (Ryzen 1700) 1.18750V (1187500 in pstate) = Offset 15625

in pstate just change FID to 9a to achieve downclock and overclock.

another example for 3.825 overclock

Max volt I want 125000 (1.25000v) - default cpu volt 1187500 (1.18750v) = Offset value of 0625 (625)

in psate0 change to 99 to achieve working downclock and upclock. Am I correct here?

Max Volt - Default CPU volt = Offset value

Just a quick question on this if you don't mind. All I like to do is actually overclock the single core boost on the R7 1700 from 3,7 to 3.9 if possible when doing CAD and leave the all core at the present clock so it does not heat up and consume so much wattage on rendering times. I don't play games so this is my workload. I am currently on Arock AB350 Pro$ that has the same AMD CBS feature.

Seems right just test it all to make sure it's good, monitor your volts at load etc.

Sorry no idea how to adjust single core boos alone.

Hey guys, I wanna ask you, maybe anybody know. I can tune fan speed in BIOS in correlation with CPU temp. But as I see in HWinfo there are two cpu temp sensors:
CPU tctl/tdie (i think its more precise because it obviously report temp directly from cpu)
simple CPU - it shows frequently numbers lower then tctl/tdie about 5-7°

so when we control fan speed from BIOS what sensors readings motherboard use? It's important to correct tune curve of fan speed. I guess that second but i'm not sure.

anyone have any luck overclocking ram or a simple tuitorial on how to? i'm sitting on 2133, everytime i try to use the xmp profile it goes into a boot loop, and doesn't post.

Same here. I have 3200 MHz 2 x 8 g.skill. No luck for me either lol.

You can try the below from Guru3d's review of an Asrock x370 board:

Did you get stuck at 2133 or 2400 MHz with faster capable memory?

I recommend that in order to get that Ryzen running properly you do the following:

Clear CMOS, fully power drain the system
Load optimized defaults, save & exit and reboot (DO NOT CHANGE ANYTHING ELSE at this point).
Enter BIOS again and apply the recommended, say, 2933 MHz setting (16-18-18-18-36 and 1.35V), save & exit.
We have seen numerous cases where boards can refuse to run properly following a component change, clear CMOS or memory training fail (i.e. too high clock was applied). The “trick” is the step #2. Normally at that point you’d just go and apply the setttings you want to use but for some reason an extra reboot is needed to properly load those defaults.

Example: on AsRock if I try to apply anything higher than 2400 right after clearing CMOS (or right after changing CPU or right after failed memory training) it will always FAIL. The extra step listed above (#2) allows it to run 2933 100% and 3200 with more lucky boards + components. You can find the recommended DDR4 voltage and timings on the sticker if XMP does not kick in.

Also, around 20:30 he explains exactly what the LLC settings are doing, very informative.

Guy can't even calculate watts correctly, why bother about him trying o explain more complex stuff.

Does anyone else have problems with their CPU voltage? Cpu-z for example shows a vcore of 2.5 etc, i am running bios 2.00
