AMD’s B550A chipset belongs to the company’s Promontory-LP family (B450) and therefore supports 2+4 PCIe Gen 3 lanes, two USB 3.2 Gen 2 links, and six USB 2.0 connectors. The chipset might support overclocking, but OEMs can choose to support the feature or not based on the Cooling and the Power Supply and the Processor being a 3900X vs 3900.
Using an Enermax Liqtech II 360 White liquid cooler & an ASRock X570 Taichi motherboard, Splave overclocked his 3900 to an all core clock speed of 4.35GHz at a voltage of 1.375v.
The dell isn't using an X570 chipset.
overclock and over voltage damage is not covered under the standard warranty.
Just got my r10 with ryzen 3900 and I am using updated 1.06 bios and oc tools and there is no advanced tabs for cpu or memory! I saw that this combo supposedly fixed getting back OC capability but it has not done so for me. When I go into the bios there are two drop downs that do not drop down but do say they are enabled. one for overclocking the cpu and one for the ram but there is no ability to change these settings. I spent over 2 grand to have a gaming machine that allows me to be a gamer. Fix it so we can overclock!
I use AMD Ryzen Master... So you might wanna go to AMD's site and check it out.
Also, be careful of temps... some others on this forum with Ryzen 10 3900 systems were equipped with air-cooling when liquid cooling should have been supplied.
Note:
Alienware already defaults the cpu to Precision Boost Overdrive - at least on my Alienware R10 with 3800x PBO was enabled in BIOS outta the box! That seems to work great and keep the temps in check - at least with a liquid cooler
Incorrect, but thanks for replying. I can overclock all day long in Ryzen Master but in AWCC there are no overclock tabs for the 3900.
Edit: Also, the table you showed for the 3900x is interesting. I can get 4250MHz at 1.25v on all cores no problem (stable), something that table says only 6% of 3900x's can come close to.
AMD’s product warranty does not cover damages caused by overclocking, even when overclocking is enabled via AMD hardware and/or software.
Precision Boost Overdrive requires a compatible AMD Ryzen Threadripper, 3rd Gen AMD Ryzen 3, Ryzen 5, Ryzen 7, or Ryzen 9 processor and a motherboard compatible with one or more of these processors. AMD 2nd Ryzen processors including the Ryzen 3200G processor are not compatible with Precision Boost Overdrive. Because Precision Boost Overdrive enables operation of the processor outside of specifications and in excess of factory settings, use of the feature invalidates the AMD product warranty and may also void warranties offered by the system manufacturer or retailer.
AMD Ryzen features and benefits depend on system configuration and may require enabled hardware, software or service activation. Not all features are supported on legacy platforms.Performance varies depending on system configuration. Check with your motherboard and system manufacturer.
Max boost for AMD Ryzen processors is the maximum frequency achievable by a single core on the processor running a bursty single-threaded workload. Max boost will vary based on several factors, including, but not limited to: thermal paste; system cooling; motherboard design and BIOS; the latest AMD chipset driver; and the latest OS updates.
I too can get 4250MHz at 1.25v on all cores no problem using ryzen master. Also easily getting 4550 on one core and stable and no temp issues on water cooling.
@speedstep: We just want the ability to do the same thing within the alienware platform which is what we expected. The 3900 is a very capable processor and and it's really the best of both worlds... I can go full eco mode and have crazy low temps and low power consumption but in rendering or in-game have insane horsepower. Thanks for responding though, it's always worth having something rather than nothing.
I just read this thread. I noticed R10 motherboard is described a B550a (as in the Dell R10 manuals) but why is CPU-Z 1.92.2 reporting it as X570 ? I cannot imagine any B550 motherboards (like the ones from motherboard vendors) are a derivative from B450 simply because the AMD slides does not offer basis to support that design.
*Suppose* if the R10 motherboard chipset is a derivative of X570, it would mean that the CPU to PCH bridge is a PCIe G4 x4 connection, but gimped to limit connectivity and expansion. Would this be a possibility?
Is there a way to confirm for certain, that the chipset in our R10 boards is a B550a ("a" variant being OEM specific) vs a X570 ?
Does anyone here know what's the PCI DID for a B550 (boot up linux on a true B550 mobo) and compare that to a PCI DID of X570 chipset mobo? I can only assume that having both values will help in deciphering for certain what chipset we have on our R10 boards...

I don't find DELL or AMD information showing the Aurora chipset and Bios supporting Overclock for Ryzen 9 3900 clock speeds 3.1GHz base,
4.05 GHz all-core Turbo
4.35GHz single core Turbo

You chose based on price.
The tradeoff is that you cant overclock
All Threadripper CPUs are overclockable
High-end desktop (HEDT)
https://www.amd.com/en/where-to-buy/ryzen-threadripper
AMD Ryzen 9 3900X
105W 3.8 GHz
AMD Ryzen 9 3900
65W 3.1 GHz
On a manual all-core overclock, the 3900X max clock speed is limited with very few processors reaching 4.2Ghz 1.250v

you are wrong. With proper cooling the 3900 has been very overclockable.
do a search....

ryzen master is ok.... also I have water cooling and have had no issues with temps or fan noise either.

Is there another solution? I still can’t get mine to show up and have done the other solutions.

AMD Ryzen™ 9 3950X is over clockable
AMD Ryzen™ 9 3900 65W cpu is not.

" all day long in Ryzen Master"
https://www.amd.com/en/technologies/ryzen-master
So lets see your screen shot on a dell with
3900 65W
vs
3900X 105W
I see no documentation from AMD or Dell supporting your overclock claims.

Not that I have to justify myself to you, or anyone else for that matter, I will humor your request. https://ibb.co/HNWn3SL https://ibb.co/34xp9z6
Edit: and since you can't seem to find info regarding the 3900...
