Your 1933fclk results sound exactly like my 1900fclk ones.

I did try 1933 on mine - PC refuses to boot. Going to wait on a new AGESA release for my board to give it another spin - I'm on 1.1.0.0 patch C right now.

abit slow to join d party but better late than never.

havin d 1900fclk black hole as well, 1933 & 1966 booted fine. glad to see amd imc finally gettin closer to what intel is capable, not quite matchin but almost there.


4k finally done with some helps from d beta bios (new ageesa)...

Nice....I'm still stuck with the 1900IF black hole...And my RAMs cannot do CL16 unless I set 1.4v in BIOS

But the thing is with my board, even with setting XMP 1.35v in BIOS, the VDIMM reading in BIOS and HWINFO shows about 0.3-0.6v offset..1.38v idle and 1.41v load.

Ryzen Master and ZenTimings still show 1.35v tho...I don't know which voltage reading to trust so I just set it at 1.35v theres no voltage pins on the board for me to measure myself

micron b imo dont really like tight timing bro. for 3600 & above, i remember i did 18-22-22 all d way. could be diff on 5k (i tested it on 3k) & probably newer agesa. yup, giga vdimm fluctuate kinnda big from what i remember on x570i as well, at least + 0.03v in my case b4.

Opps sorry typo on my part there, the offset is 0.03 to 0.06, not 0.3 to 0.6

Yeah I'll just live with rams and board, and do what I can to tweak it as much as I can.

BTW did you tweak ur CO in your hyperpi runs there?

Hi, any idea on this?

With PBO 2.0, offset 200Mhz, Curve optimizer -21, R20 43xx score
Seems like the effective clock is much lower which I do not understand.
With manual OC 4.7GHz, R20 26xx score
Power setting for both are the same (Auto)

What did you set your PBO limits (PPT, TDC, EDC) to? If its stock 5600x limits (i.e. 76w 60a 90a) then it makes sense for the effective clock to be limited to those values

But if you already set PBO limits to motherboard, idk...maybe someone else can help?

I'll test the 200mhz settings for a while to check if mine also give the same behavior, brb

Edit: ok no point in testing, since I remember I already did this before. with pbo limits set to motherboard, the mhz offset will help single single thread, but wont help much in multithread since its already the silicon limit. during CB MC runs is still around 4675mhz for me, but SC does boost to 4850mhz

From Ryzen master, it shows:
PPT 395W
TDC 160A
EDC 190A

Any idea which setting in BIOS will confirm this numbers? My motherboard is Asus B550M TUF

Edit: My PBO limit is set to "Disable"

AFAIK the only way to check in BIOS is only if you set the PBO Limits to "Manual" and change them.

In windows, either use RM to check like you did, or use HWINFO divide the watts/amps with respective percentages:


BTW on my board, setting PBO Limits to "Disable" is setting it to default 5600x limits i.e. 76w 60a 90a. Screenie of my UEFI setting and the respective RM screenie during CB MC run:


Perhaps ASUS implements the PBO Limits "Disable" differently...sorry I cant help...

i think i get d best boost clock when:

1. pbo limits: auto
2. scalar: auto
3. overide mhz: 200mhz

co @ all core -1, vcore @ override + offset > auto + offset 0.25v

gettin 4850Mhz (highest, sc ofcoz), in games @ 47xx-4850Mhz, heavy loads @ 46xx-47xxMhz...

a good read over HERE (@reddit)

For my daily settings i cap at stock PBO Limits, as the 20% increase in power consumption and temps are not worth the 10% increase in performance. Furthermore, that 10% performance increase is also only reflected in benches and not my actual gaming experience since I'm gaming at 3440x1440 and GPU makes a bigger difference. I tweak everything focusing on power efficiency for daily profile, even my GPU is undervolted..


Nonetheless, when I'm doing bench runs, I unleash everything with manual OC

i focus more on uv, imo there is no point to manual oc nowadys, keep d chip as cool as we can (including uv) then d chip will take care of d rest by itself.

as long as gaming @ 60c ish i cant ask for anything more from a 6c chip with an entry level aio (a cheapo cm ml240).

I agree. I'm also worried if any of my components get higher than 60c.

I observe no matter how much cooling potential is available, the die temp of these zen chips will still spike quite high if I unleash it, prolly coz of the small physical size of the die itself and heat transfer from the die to ihs to coldplate not efficient enough. Thinking to direct die but I doubt it'll make much difference. Also prolly coz I use a cheapo block lol

Over 60°C is common during heavy loaded (gaming, 3D rendering and video processing). Even on water-cooling I can get 65°C on gaming under normal room temperature. Normal usage on normal room temperature it will hit 48~55°C. If turn on air-con 28 degree Celsius, the temperature drop to 44~49°C degree Celsius.

On my old Intel, it hit 88°C~99°C when I run video processing on Adobe Premiere Pro under 28°C air-con room. If I forgot to turn on the air-con, my old Intel will over-heated and shutdown when I run video processing on Adobe Premiere Pro on normal room temperature. (5th generation Intel processor with Intel heatsink with fan).

For Asus board, I set everything in AI Tweaker to Auto, and set then everything that I wanted at Advance>AMD Overclock. Then only PBO 2.0 work as supposed...
Wasted a lot of time trying different method between the AI Tweaker and Advance menu. There might be bug in the AI Tweaker portion messing with limits.

Haven't run any superpi/hyperpi for more than a decade.



What actually affects it the most anyway? cpu/IF/mem/everything?

Edit: found a really old post of mine...last time i did superpi runs was with an athlon64 3000+ venice with DDR1...that time 1M superpi took 30seconds...now 10seconds..i expected much more improvements (prolly should be around 5secs?) for 15 years of tech advancements....

i'd say ai tweaker is under asus while advanced > amd oc is under AMD. usually i will set both d same, especially for pbo setting.

nice run bro, way more efficient than my attempt. i'd say cpu clock > imc freq = ram freq + timing. most importantly, os must be optimized i think.

ahh ok that last part makes sense. This os is a clean install when I migrated from devilscanyon 2 months ago. thanks!

For Ryzen 5600X, what voltage should I target for peak voltage?
If let it run auto, it will peak at 1.45V.
If I put Curve Optimizer -30, it would still peak at 1.4V.
All core load will stay at 1.3~1.35V
Is it safe that way for daily usage?

Hi everyone, I have a 5900x and I kept it at stock settings for PBO. However when playing COD:Warzone the temps can go up to 82c-84c on average but no performance drop whatsoever. Below is my setup:

Processor - 5900x
Cooler - NZXT X73 Kraken 360
Mobo - X570 Aorus Pro Wifi
Casing - Corsair Carbide 275R

Anything I could be doing wrong here? Thanks.
