Ryzen 5000 series overclocking

I couldnt't find much on here relating to the overclocking potential of the 5800X, 5900X and 5950X CPUs

There is a dodgy looking article which shows the 5950X being overclocked to 6Ghz another article says 5Ghz

https://www.techpowerup.com/273426/...rocessor-overclocked-to-6-ghz-and-geekbenched

https://www.somagnews.com/new-information-on-amd-ryzen-9-5900x-vermeer-cpu/

Max boost is 4.8Ghz already which i'll be happy with but if it can reach 5Ghz then great.

The RAM I have is Team group 8 pack edition 2 x 16GB - https://www.overclockers.co.uk/team...00c16-3600mhz-dual-channel-kit-my-002-8p.html

16-16-16-38 & 3600 MHz guaranteed memory clocks

Is there anything I should be aware of in terms of Ryzen overclocking like leaving XMP disabled or enabled, not taking Vcore past a certain value, or enabling / disabling specific optiions? Motherboard will be an X570 MSI MEG Unify if that makes any difference
 
I don't feel there will be much headroom from experience with 3000 CPUs - not all core to 5Ghz for normal bods. But we need to see what happens at release.

I doubt there will be based on what I have ready, however some people already have 5800X chips (on here) maybe 5900X and 5950X too so potentially people are already overclocking them.
 
I've not used AMD for best part of 20 years so a bit out of touch, but does the max boost figure of 4.9ghz relate to single core only?

My current 7700K is sat at 5ghz across all 4 cores, via an option in the bios, can similar be done in the bios on AMD chips?
Not expecting 5ghz across all 16 cores BTW :D

dont need to OC Ryzens, pbo2 does the work.
enable and sit back and enjoy

Cool, i'll look for that option in BIOS. Not need to change voltage or DRAM timing or anything any more? There is an auto overclocking feature on my current Intel board, but it's gonads and crashed my machine the last time i tried it (maybe 6 years ago)

Same boat as me, K6 2 450 was the last ADM I think I owned! From AMD Ryzen 5900X website

"Max boost for AMD 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. GD-150. Learn More."
 
Just enable PBO and increase the motherboard PPT, EDC and TDC limits and let the processor overclock itself. Much easier and no stress testing required. :)
 
Ryzen have given their cpu's bigger shovels to move more data at the same rate and have opened up the cache to allow for it to move without all the latency issues hence why the need to o/c lol!

I have a feeling these things (PPT, EDC, TDC) which I have not heard of will not be labelled as such in the motherboard options. Think i'll wait and see whats in the advanced options in the BIOS. The manual has an 'OC' section but does not mention PPT or TDC

EDC it says
Relaxed EDC throttling [Auto] (optional) Relaxed EDC throttling reduces the amount of time the processor will throttle the cores.
[Auto] AMD's recommendation
[Enabled] Reduce the amount of time the processor will throttle.
[Disabled] Part-specific EDC throttling protection enabled.

Those options are available under the Precision Boost Overdrive section of the BIOS, you can also increase them using Ryzen Master Tool Software without the need to enter the BIOS. Examples below.

Platform Power Threshold (PPT) is the total power capacity in Watts at the processor socket and includes Memory controller power for a CPU (not for an APU)
Thermal Design Current (TDC) is the total current capacity in Amps at the thermal throttling limit of the processor
Electrical Design Current (EDC) is the total current capacity in Amps that can be supplied to the socket

Prob wanna overclock that Ram to 4000mhz, hoping 2000mhz IF is the sweet spot this time, anyone know for sure yet, is 2000 IF attainable on all 5000series?

Thanks for this. Sure it'll help a lot and will get the Ryzen Master Tool Software
 
I'll be upgrading next week (fingers crossed) to a 5900x paired with a X570 board (Looking at the MSI ACE board or Aorus Master) but i haven't touched AMD hardware since my old Phenom x4 955 days and 5870. I'm upgrading from a 9600k so hoping for a nice bump in single and multicore performance.

Regarding overclocking, im guessing its totally different to intel. What is this PBO you guys mention?
 
I do not find the need to manually OC. AMD have done the work with PBO.

Having said that, I have seen okay results by tuning the vcore (slightly undervolt) with PBO limits relaxed - as par Matts suggestion above.

Should add. RAM is key for Ryzen, learnt a hell of a lot since owning Ryzen.
