[SOLVED] Overclocking 3700x

[freddyflo]

Hey fellas I'm new to pc building and built a pc with a 3700x and I would like to learn how to overclock my CPU but on AMD it seems a bit more complicated. I turned on PBO advanced on my MSI x570 unify board, upped the core max boost at first to 200 then 400. As is in CB20 single core boost touches 4450 and for about 70% of the run stays at 4425. I'm trying to see if my chip will overclock all core to 4.4 though but need some help anyone out there willing to help me out? Temperatures are great the cpu rarely touches 60 in aida 64 it topped at 66c with everything checked off CPU, FPU, and the cache I think is what im suppose to check off but in all honesty i have no clue.

So will only overclocking tell of my lottery winnings or will bench marking tell? If so bench marking which ones?

LOL...I think only benchmarking will. But comparing it to find out is a bit difficult if you don't know exactly what they did to get their scores.

Also, in PBO your lottery winnings have to includes great cooling since a bad cooler, bad placement or poor case ventilation can easily kill processor performance.

What are your CB 20 scores? both multi thread and single thread? The most repeatable way to do a CB20 run is right after boot up and with real time priority for the task set in Task Manager. Make three runs and average them, or just show the range. Usually one run is enough for single thread as it doesn't heat the cores up very much; it also takes unbearably long.

EDIT: I also think the concept of 'silicon lottery' is a bit tweaked with Ryzen 3000. AMD's really binned the cr4p out of these 7nm chiplets. Any 8 core chiplets that could win in the silicon lottery either go to 3800x's, or to 3950x's or to other CPU's, including Threadripper or even Epyc, depending on how it does in binning.

Really, 3700x's are the bottom tier aside from disabling one core and putting it in a 3900x or 3600/x.

Exactly. Unlike Intel, amd takes TDP values quite seriously, when they say 65w, that's exactly what they mean. TDP isn't heat output, it's original intention is Power, and ppl setting a manual voltage of 1.325v never bother with current limits. Which then puts the cpu in jeapordy.

65w tdp:
PPT : 88w
TDC : 60A
EDC : 90A

PPT is load maximum use. TDC is maximum current. EDC is spike current, extreme short usage.

So you can push a 65w Ryzen to its 88w socket limit, with upto 1.46v to maximize the 60A, but that has the same affect as running an intel cpu at a constant 100ish°C. If you want to push the higher voltages, you need to drop the current maximum, like dropping the temp to 70°C, so @ TDC 40A. Leaving the TDC alone will require lower voltages, like 1.2v. Balance.

Personally, with a Ryzen, manual OC is pointless, better to get a good cooler, set PBO and the autoOC and let it do its own thing on auto.

How do i set the auto OC? you mean the cpu max boost?

I'm honestly trying to find my lottery silicon without overclocking idk how else to figure it out

With the way AMD has tuned the boosting algorithm for Ryzen in conjunction with their binning process, the best way is to use PBO. Something else done in the binning process is determine the optimal operating parameters for the processor and fuze them in at manufacturing: it's called the processors FIT values. That includes the safest voltage and frequency to operate at for a given temperature and supposedly it's specific for each processor.

So in effect, AMD's figured out the best your silicon lottery offers and given you the values in a way to let you exploit it in relative safety. Leaving volts and multiplier in auto means the processor boosting algorithm has authority to change both those things to stay within the FIT values. All PBO is doing, when done right, is overcoming motherboard power delivery limitations due to conservative, missing or downright bad, BIOS settings by the manufacturer so the boosting algorithm can work the full range of programed FIT settings.
