Subject: x470 Taichi - P2.0 XFR/PBO
Date Posted: 27 Dec 2018 at 1:42pm
New owner of a x470 Taichi paired with a 2700X. I am looking for information regarding configuring XFR/PBO. This BIOS is a bit different from my C7H and I'm struggling some finding my way around and translating the available options.

In OC tweaker:
Changed OC mode to Manual
Left the APU/PCI freq at 100
Left CPU Freq and Voltage to Auto AMD CBS
SMT mode Enabled

Enabled XMP profile for RAM
DRAM 3200

Advanced:
AMD CBS \NBIO Common Options\XFR Enhancement
I accepted and set to Enable

I left everything else at defaults.

System is working pretty well and almost as good as my C7H also with a 2700X (I think that chip has better silicon but I am not swapping cpu's to confirm. I think it's just my unfamiliarity with the ASRock eco system that's holding me back some. I keep thinking there is more that I could be doing (not including mem tuning, I'll do that after CPU is set). Any helpful advice is welcome as to what I could look at. I do not want all core OC. I like XFR/PBO and as it stands what I stumbled through is not doing all that bad. I just think there's more for to look at.

i've been told to reduce the cpu vcore further to get more clocks

other than pstates and ram timings its pretty much it

Thanks - I did a little bit of tuning. I added an offset -0.08750 which interestingly enough raised my VID up bit but not dramatic but from 1.444 to 1.456V For grins I tried adding some bclk. I was only stable at 101 something in my system did not like 102 it would lock up after 5 mins or so in the OS. But 101 was stable for 90 minutes of prime95. I did notice that Core Temp was displaying some of my core freqs as 7447 MHz ... so that app at least was not liking it and I did not do any diskmark bench's to see if pcie i/o was stable with my nvme or sata's but I did get a decent cb score.

I ended up dropping the bclk back to 100 because I know I'm solid there. I did a couple cb passes there and Im hitting mid 1881-1886 consistently.. I'll keep playing with the offsets and tighten the timings on the me kit. Which I had up to 3400 with the XMP cl14 3200 timings no worries.

Ended up with the following:

Left BCLK at 100
Enabled PBO
vcore offest -0.08750
Tune ram via Ryzen calculator, fast settings.
DRAM 3.365

All core under load 4175
PBO boosting to 4350
idle 2200

I may want to try dropping ram to 3.55v but for the sake of this thread I'm done.

It seems the negative offset is limite to -0.1V.

It would be great if this could be increased so we can try even lower.

Given the chips have been out for over a year and e.g. my new one is on stepping B2, the latest (good quality) ones may well be able to run at an even lower voltage.

its a lottery if you can go lower -0.1v my system isn't stable lower than -0.075v

Absolutely.

Every chip/setup is different. It's good to have options though. :)

oh i didn't know if it cant go beyond -0.1v but i think its a thermal thing than the voltage

Mine seems stable at -1.0. As discussed, lowering the voltage lowers the temps and if there is still sufficient voltage for stability, results in higher boost clocks.

I'm using a Cryorig Universal but with only the middle fan as the outer one sounded scratchy.

I mean -0.1V in the previous msg of course. Recovering from eye surgery and have very blurry vision!
