AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

[Captain]

So why is the 3900X the direct replacement for the 2700X then?

It's not, the 3700x is.

Personally I would have left everything default (except RAM) in BIOS and use Ryzen master first.

It's what I do. Not touched the BIOS.

Tbh, i think it is the 3800x really, the 2700x isn't a low power chip and the 3700x is a low power chip you see like with the 3600 when compared to the 3600x you see.

The 3700-3800 are direct replacements for 2700-2700X. And given the perf difference some might argue the 3600X also.

So why is the 3900X the direct replacement for the 2700X then?

Why is Cypress (Radeon HD 5870) a direct replacement of RV790 (Radeon HD 4890)?

Why is Ryzen 7 1800X a direct replacement of the FX-8350?

Another question for you guys.

I have volts of 1.4 and I've downclocked 6 of my cores to 3.7 and the other cores are at 4.350. When I run CB my temps are close to 95, which is exactly the same as if I have all cores at 4.3.

So why are the temps the same. Surely there should be lower temps or does the fans profile really suck on the stock one?

My comment was aimed at a comment that he made previously, where he whined that the 3900X was too expensive since it should have been priced at 2700X levels since according to him it was its direct replacement.
We all know that the 3700X and 3800X are the direct replacements for the 2700X.

@Gibbo Any news on 3800x and 3900x stock?

 

[fs123]

Anyone seen this?

Could be a 10% increase in performance for some if their bios settings are forcing the Infinity Fabric to a lower clockspeed.

 

[andy_mk3]

Yeah seen that. Set mine to manual but it was right before, so made no difference at all.

Awaiting news too. I've ordered the 3900x, a GPU and an NVME SSD from OCUK. It's the last items I need for my first new build in 6 years so the wait is killing me

Thinking of downgrading to the 3700x but 50% improvement in multi-core speed is worth it for me.

Sucks that you have to wait. The 3900x is an amazing cpu though. Its worth the wait. Been playing Battlefield V a lot today and it makes use of a lot of the cores (about 14 threads are always 75%+) and it makes for an awesome gaming experience.

Lol, someone putting a 1 star review on amazon saying that the 3900x should have been £270 as it’s the 2700X replacement. Think they’ll find that’s the 3700X. 3900 is a whole new Ryzen 9 series. Idiots.

That was regarding the 3700x, as can be seen from the size that was reviewed.

Right as promissed here ya go.
Settings that are on AUTO i tested manual up and down and could not get anything more from changing. Took me 6 hours of messing around and testing to get those 0.2ns down. And gained 10-11 Cb20 points.
This is for Teamgroup 4133 8 pack ram that is on promotion This week for 153 or so quid.

Well, unless there are developments with overclocking, bios settings, or bios updates, I've given up even trying it, just stuck PBO and make do with 4-4.1 total overload (prime 95) and 4.2-4.3 games. I tried turning LLC on and setting voltage to 1.45 and even then Cinebench wouldn't run at 4.3GHz.

 

[Colonel D]

My delivery is on hold since Friday, so hopefully it'll be with me tomorrow and I can start to build it

 

[DragonQ]

Does anyone know if a constant 1.4v for the CPU is fine for the 3700x

I'm sat at it right now as PBO is crap on my machine but worried I'm gonna do damage!

AMD recommends 1.325 V long term.

How exactly do you switch PBO on?

 

[andy_mk3]

For ALL CORES.. anything up to 1.5v is normal and safe for light loads.

In bios or Ryzen Master.
