Moving from 2700x to 3800x, OC advices

[wsarahan]

Hi guys how are you?

I have a Gigabyte X470 Aourus Gaming 7 Wifi and the 2700x now running at 4.2 all cores

In this Black Friday i got at a good price the 3800X , i would like some advices to overclock it, the CPU will arrive this tuesday, i was reading some posts and seems that to achieve 4.4 the sweet spot is something about 1.3 right? But i wanna more ideas and advices

As we don`t have PBO at 2700 series when i change the cpu it will appear at the bios and i will have to disable right?

Sorry for my english, i`m from Brazil

Thanks for everyone

Thanks, just downloaded the power plan and will apply after i change the CPU

So manual OC at 3000 series is a waste of time?

 

[wsarahan]

Yes. The autoboost through the powerplan & bios work best.

Just one more question

Do i need to make the changes at the bios that the guy that made the plan posted?

• Global C-state Control = Enabled
• Power Supply Idle Control = Low Current Idle
• CPPC = Enabled
• CPPC Preferred Cores = Enabled
• AMD Cool'n'Quiet = Enabled
• PPC Adjustment = PState 0
• I also recommend disabling PBO, which activates Precision Boost 2.0 for clock management. This ensures only temperature and FIT play a role for clock speeds

Or just apply the plan ?

Guys i ned a little help again

My 3800x arrived

With PBO i cant get a good score at Cinebench for example, something about 4800/4900 and i can see at Ryzen Master that the cores goes max at 4.250 full load running the test

I tried manual OC for yesterday all day long and got a sweet spot at 4.4 1.337 vcore LLC Turbo and VSoc 1.1

With this config i can get 5200/5300 at Cinebench and almost the same temps with PBO

Now i have 2 questions

Why my PBO is so low? And can i stay with this manual settings as it seems better at performance? Even at single core it`s doing better, this vcore and all other configs are safe for 24/7 usage?

Tks again friends

What cooler are you using?

the nearer you keep the CPU to 50C the higher the all core OC are.

Manual OC simply force the clock to ignore PB.

Don’t really see the requirement to force a manual OC through, Id rather overclock the RAM and FCLK which gives a much more generous prrformance uplift.

I can`t remember now the correct model, it`s a deepcool 360mm AIO cooler

The problem is that i live in Brazil, very hot country, even with AC, for example, at Cinebench i get the same temps at full load, something about 73/75 during the test, manual OC or PBO

4250 for all core load is normal (that is with pbo working, should be lower on stock) , locking your chip at 4.4 , when it should boost itself around 4600 (with pbo,xfr) is not a great idea, but some ppl do it for lower temps or their task requires higher allcore, 1.275v is safe for 24/7 (iirc) as mentioned above- memory overclock that what is going to give you the most performance boost, but it takes much longer

I don`t have pacience to OC the memos, just use XMP kkkk

I think i won`t be stable at 1.275, and i never boosted to 4.6 with PBO i really like that this happened

How do you check freq ? Hwinfo64 - is probably the best and easiest tool to use, for a real world , just run ingame benchmark with allcore locked and pbo auto overclock , few times each and see what gives you higher points ( 9 times out of 10 pbo will win).
