Ryzen Owners Zen Garden

Official statements from AMD reps said the "sweet spot" for Zen 3 ram (and Zen 2 for that matter) was 3600MHz. We could split hairs about whether any non-JEDEC RAM speeds should be guaranteed or not... but I'd much rather find out if there are any known simple settings in my BIOS that I could bump up in order to make my USB stability better.

That is the performance sweet spot when overclocking, NOT a factory supported speed!

USB stability is tied right into PCI-E and DRAM stability - make sure you're actually stable with your RAM settings, and dont use PCI-E risers

I passed the Karhu test for an hour. This is good info though, I'm going to try giving both my DRAM and SOC voltages a modest bump to see if that helps any. Thanks!

Just wondering that as I have PBO +200 enabled, can I rise my max TDP to 95 or even 105 watts? If that doesn't help that much, I may as well try 65W TDP..

My college from work is troubleshooting a PC from the local uni. Some idiot cheapened out and bought memory that wasn't on the QVL - PNY, Ubuntu is acting weirdly, Chrome takes 2 min to launch etc. No wonder:

So, a 5950X, X570S Elite, 3090 (!) and some shitty 3200 RAM from PNY. Mobo can't even read the XMP from this POS, it defaults to 2666.

Told him to set the primary timings to what should be xmp, set speed to 3200, VDIMM to 1.35V, adjust VSOC to 1.1V and verify if infinity fabric is running at 1600. Or just go and tell them to change ram to something that's on Gigabyte's QVL.

Looks like four 16GB sticks, so they're running 8 ranks

That'll be fun to get working for beginners, but raising VSOC before enabling XMP should do it

Yup, 4 sticks.

You have to look at 3 different voltages for the USB issues which maybe related to FCLK drop out.
SOC/IOD/CCD you have to find the settings that is not to high or too low.

Both too high or low voltages can cause USB issues.

What exactly doesn't it "help" much? Those are two not really related things.

+200 applies mostly to single thread (unless somehow you're getting 4.4GHz all core out of a 3600), and only if you're lucky enough to hit 4.4.

Power limit applies mostly to all core, because single thread is only like 30-50W max.

Your TDP is already 65W, it's PPT that's 88W. You can set PPT as high as you want, doesn't mean it'll go that high. On PBO (not manual OC), single CCD Zen 2 completely maxes out at like 110W, and you don't gain that much compared to stock.

Alright, you said it clearly, thanks.

Kinda sounds like man just doesn't know how to take care of his computer and there's probably a host of other things going on there. I don't think I've ever seen noticeable slowdowns on any OS because of running JEDEC 2133 - until I fire up a game, of course. Ryzen 3000/5000 is good like that

Or maybe it's a Ubuntu thing. Been a hot minute since I last had LTS on 4650G and 5900X

Alright, you said it clearly, thanks.

Reading all this made me reminisce about losing the Ryzen silicon lottery 6 out of 6 times

Set a bit of PBO or just leave at stock and enjoy life and the lower temps you're not missing out! Don't let the benchmark score chasers fool you

4 tries later, I have learned my lesson about being an AMD early adopter

That's a machine that was purchased by the University through a tender, so the lowest offer won.

I doubt they even booted it before they delivered the system.

slap the cheapest parts together and let the user deal with it!

And charge $4300 for it. Don't forgot the magic clause "System will be tested after delivery", lmfao.

Hi everyone.

So, I got a R5 3600 on a b450 MSI motherboard, and I see that I have a couple options there on my motherboard that till today I haven't messed with yet: Precision Boost Overdrive, which was set to AUTO, now I set to ENABLE, and tried a few games. So far I did not see any difference.
In games seeing through MSI AFTERBURNER my CPU boosts to around 4050, 4025, 4100, just as it did before with PBO set to AUTO.

Now I see there in the mobo another option called GAME BOOST. Anyone have tested? What exactly is that?

Also, if I try this "game boost", sould I set PBO back to auto, or can I leave both enabled?

Dont use game boost


PBO lets your CPU boost higher if wattage is available and it's cool enough - but the 3600 is already very close to it's limits so it doesn't boost very hard. The setting helps more on higher end CPUs.


TPU's review of the 3600 found an entire 0.3% boost with PBO enabled

Game boost sounds like one of those terrible auto-overclock features that cranks voltages up and overheats everything

Edit: yes, that's what it is. Don't use it.

When I was using Zen 2 briefly, I found a static OC to be more satisfying than letting the CPU boost on its own. I had a 3600XT and I just ran it at 4400-4500 static.. I thought its boost algorithm was not very good.

I agree, on my old 3600, which was an early release(bad clockers). I had it at 4.2 from the day I got it to the day I sold it. Performance was more consistent as the boost was not very well implemented. Good chip though when I had it paired with a 5700 XT and then a 3060 Ti.

On this 5700 now, I don't even care about it. Because I play at 4K I just run it on eco mode lol and performance is smooth as hell with the 3080 doing the vast majority of the heavy lifting

 

[Mussels]

lower model ryzens of every gen typically benefited more from all core OC's

The less cores they had, the less heat you had to deal with - and they usually had a smaller boost range (unlike the 5800x which goes from 4.4 all core to 5.05 single core, with PBO on which is a large range to cover)

Do I have a golden chip perhaps ?

Both too high or low voltages can cause USB issues.

Thank you! This is exactly the kind of answer I was looking for.

So I finally decided to mess around with Ryzen Master on my R5 3600, and my first try was an 4.2 all core, at 1.25 V. Did some testing and it is stable so far.

Is this voltage ok? What would be the higher you guys would consider safe, in case I have to bump it up a bit? I hear some people saying that up to 1.35 is ok, some say it is too much.

I can try to lower it a bit too.

EDIT: I set the voltage to 1.2 now, and it seems to be OK. Temps have dropped to a max of 75C in stress test at 4.2 all core. I think this is fine.

1.25 is perfectly safe. 1.35 would degrade, although probably so minimally it doesn't matter. I ran my 3900x at 1.4v for over 2 years before I sold it. Didn't degrade at all. However, I would not recommend running it at anything higher than 1.325v if you want it to run it daily for years.

Heat also plays a part. If you are at 75c @ 1.2v, you shouldn't go much further. You will end up pumping more volts, increasing the temp which in turn makes that overclock unstable. It's counterintuitive.

Hope this helps.

Thats great to hear. If I ever need to bump it up a bit, I got room then.

Yeah the 75c was during stress test. In my daily use with this settings (4.2mhz at 1.2V) the max temp I ever saw was 52c, which is when I play a heavy game, and gaming is the most demanding thing I do in this PC.
