Ryzen Owners Zen Garden

true. i tend to set and forget tho. this not being able to set things myself is going to bug me til new bios is released with the x3d agesa, assuming that update should correct it. One would hope anyway.

ryzen master saves the settings to the BIOS for you, if you remove it the BIOS settings remain

Even if you dislike it, for testing individual cores it's the lazy and easy way

I haven't been following this thread, no idea whats going on. Listen to whatever @Mussels says

I've only worked on one AM5 system so far, and that was remote controlling a 19 year old girls hands over facebook messenger - i learned a few oddities and tricks of the platform, but theres definitely unique bugs and some involving PBO that we just stayed well clear of

This chart represents something different, but if you decrease your temperature limit, you kind of limit the CPU the same way as with worse cooling

100% correct

But as an example, passing 75C makes my ram OC unstable - so i'd rather lose 1% performance in a long gaming session when my loops warmed up, than risk stability or drop the ram down to 3600

Was unaware. Thank you for that.

I agree. And I'd rather lose 1% by leaving everything on Auto, than tinkering in the BIOS for half a day. You don't feel that 1% anyway, so what's the point?

There's nothing wrong with OCing, though - each to their own, as I said.

I'm at a point now where I'm a bit stuck. I'm using PBO advanced, CO is -30 across all cores, +175MHz on Boost override and PPT 125, TDC 85 and EDC 130. I just set the CPU voltage to 1.2V and now what was a R23 score of 15,997 is now in the 13,000's. Also, if I try to use the FFXV bench it gets to 4000 or so points then hangs and resets the PC. Any help would be greatly appreciated.

I just set the CPU voltage to 1.2V

Why?

 

[Blaeza]

Why?

Honestly, I don't know. I don't really know what the fuck I'm doing, so I'm guessing, but still trying to be careful at the same time.

The 5000 series CPUs do not like low voltage. What you are doing worked on 3000 and below but not for this series.

So what kind of voltage do I feed the fecker then? I don't want to leave it on auto as that is more wrong than anything ever. Saw that somewhere on here anyway

If you're trying to reduce voltage, set a negative number for dynamic Vcore offset. Probably next to the fixed Vcore setting. Go slow, it's less likely to be unstable than performance regressions, and you will probably see losses in ST perf first.

You don't set fixed Vcore unless you are setting a fixed OC as well. PB2 and PBO scale freq/volts dynamically. At stock you might be able to do say 4.5GHz all core at 1.2V - there's not a chance in hell you will stabilize 4.7GHz+ ST boost on 1.2V.

Read some basics about how PB2 works, it's been the same since 2019. You see high vcore for single threaded loads because that's by design and at low current draw it doesn't hurt anything. Let it think for itself.

If you don't like the temps, reduce your limits. 120W+ is well into the point of diminishing returns for 8-core.

This is the thing, I don't know what I'm doing! I don't learn very easily but I am interested in getting all the performance out of my 5700X. I just want something fast, stable as a rock and better than stock. Please give me some suggestions. My tiny mind is going to pop.

Honestly, the only thing I do with 5000 is make sure my cooler is powerful. The cold plate on the InWin SR36 is so huge that it would easily fit a TR4 chip.

I don't know where your expectations are for any of these 8-cores, temps begin to skyrocket after 100W. Just follow the same advice as 5800X. There's not much headroom left.

Like I just said, dynamic offset. You'll find it somewhere around fixed Vcore in bios.

5800x (and other Zen 3 chips) PBO settings/Temperature fix

The 5800x is well known for having heat issues on stock settings, because it's single 8 core CCX design shares the same power limits as the 2x6 (dual 6 core CCX) 5900x - so it's got a lot less space to cool itself with. A big part of the problem is that motherboards will raise the maximum TDC...

Deepcool AK620 should be more than enough for 130 watts.

I shall read that slowly and carefully, thank you.

It's chiplet Ryzen, wattage means very little.

130W on Intel 10th/12th gen isn't even a challenge.
130W on a 5950X is trivial for any crappy 120mm single tower.
130W on 5700X/5800X is a different matter altogether.

The chiplet 8-cores have never been very impressive on all-core performance regardless of how much power you give them. If you get close to 4850MHz ST boost stable and respectable MT clocks, then that's all that matters.

 

[Blaeza]

It turns out my understanding of CO was wrong. I thought -30 was going to make it easier to run when in fact it's the other way round. I'm now running -3 all core and FFXV bench worked perfectly! Now I can start slowly but surely work out which core can cope with what amount of CO.

 

[JohH]

A rather unusual problem.
I have a Gigabyte B450 Aorus M motherboard I've been using w/o any display or GPU for years with a 1700X. I've been running BIOS version F63b since August.
I received a 3700X (for free!) so I decided to replace the 1700X. I reinstalled the GPU because it always prompts after changing CPUs. With GPU it booted into Linux perfectly.
But now it refuses to boot after I remove the GPU. It stops with the 'VGA' light on. It didn't do this when the 1700X was installed.

So apparently the CPU choice determines if the system needs a video card to boot?
Any ideas other than going back to the 1700X?

 

[Blaeza]

It won't boot as you need a GPU. There is no iGPU on the 3700X.

 

[JohH]

It won't boot as you need a GPU. There is no iGPU on the 3700X.

And there was none on the 1700X either. Yet it works fine. Same BIOS version. Same motherboard.
Curious isn't it?

 

[Blaeza]

Can you take a pic of your setup? I'm confused, which is normal, lol.

Exactly! What people tend to forget is that with fewer and smaller cores, the heat of the CPU is concentrated around a much smaller area and is a lot harder to get rid of. That's why a basic top-down cooler like the be quiet! Shadow Rock LP works fine with my 11700 up to around 120-130 W PL, but I need water for my 7700X at stock (142 W PPT).

They're still not exactly cheap, but that will hopefully change with the arrival of A620.

Ok, "somewhat more affordable" then....

 

[AusWolf]

What do you think my odds are of getting a used 5800x3d first week of March when the 7900x3d starts landing on peoples doorsteps? Come on folks! I know one of you out there is itching to upgrade!

I'd say pretty high, and it's only going to increase when A620 comes.

I think I'll keep my 7700X, though. A bit more cache is not enough reason to upgrade, especially with a mid-range graphics card.
