No it's normal, same as for Zen2.
That's what you will get 100%, IF at 1600 MHz.
Then it could go up to to 2000 MHz which is it's the "sweet spot".
I'd assume most if not all will be able to go up to 1800 MHz.



Sounds right to me

How it works, like Zen 2 can hit 3800 as the 'sweet spot' Zen 3 should be able to hit 4000 as the sweet spot with a decent IMC. Or like 3600 is standard on Zen 2, 3800 will be standard on Zen 3.

It would be fun to be able to exceed IF2300 like Renoir

Vermeer's FCLK should be 2133Mhz instead of 2000 only
Already >2000FCLK will very likely make issues with PCIe 4.0 ~ they haven't fixed it really

Renoir should only work @ >2200, if you enforce PCIe 3.0 , cut 8 lanes or run of PCIe 2.0
depends on what works, but beyond 2000FCLK, PCIe seems to cause many issues
Cutting 8 lanes and staying on 4.0 worked well for notebooks
For current GPUs, this might be too slow ~ we'll have to see

I have a 5600X and i can now confirm that max FCLK is still 1900, at least on my CPU and F31E bios.

I can't boot with 1933 FCLK, even with 1.2V soc, 1.1V VDDG CCD, 1.15V VDDG IOD. (1900 FCLK is working with everyting set to auto)

5600X + 3800C14 (14-14-14-14-28-42) + 1900 FCLK = ~54ns. (~66800MB/s Read -- ~30500MB/s Write -- ~55600MB/s copy)

With the same ram and an overclocked 3900X, i was getting ~63ns.

The 5600X is a monster in single thread and games.

No, i will not do any screenshot ^^


So, don't bother to buy ram of 4000+.

EDIT :

Some OC result with 5600X with a little NH-D15S with 1 fan :
4800MHZ all core @ 1.250V (not stable under avx load with handbrake)
4700MHZ all core @ 1.275V
4650MHZ all core @ 1.250V

Seems to confirm what I've seen from someone posting their results on HWBot as well.

Thanks mate.

At least there's a big improvement in latency and the static OC looks awesome
Let's hope the bigger brothers ca do better on the IF.

Yes, latency seems to be at least ~15-16% faster vs the 3900X overclocked @4.4ghz : p (maybe more with 5800X-5900X-5950X ?)

1900FCLK is easier to achieve with 4 dimm and no whea errors ... ^^ Maybe the F31 final bios will improve things.

From what AMD suggested 4000 should be the new 3800 and 3800 the new 3600.

Can't let cpu not fulfill full potential

Can't agree more

But indeed it's a very small improvement overall for a very high price.

Yes. Latency is important I have notis.

I also have extremely many chrome tabs open. But chrome doing fine to handel this pretty good. Even if it take up a bit of ram. The thing is different with 3D software I use. It only use around 30% of the CPU.

Like I said before. Software need to adapt to multi core CPUs. So everyone need to start to demanding and push software companies to building for the future

4 DIMMs harder to OC than two DIMMs as X570 boards are Daisy Chain. Maybe someone test with two DIMMs?

what ram kit are you rocking?

 

[GoforceReloaded]

what ram kit are you rocking?

F4-3800C14Q-32GTZN @1.60V only for these test ^^. (1.50V is stock voltage)

4 DIMMs harder to OC than two DIMMs as X570 boards are Daisy Chain. Maybe someone test with two DIMMs?

No luck with 1 or 2 dimm so far.

I know someone who use PVS416G440C9K (viper 4400C19 2*8GB with the same timings of 14-14-14-14-28 @ 3800 and he can't do 1933 FCLK) with a B550 aorus master + 5600X.

 

[MyUsername]

I'm actually not surprised and somewhat relieved 2000MHz IF is not the new 3800. I'll be interested to see if 2*16 B-dies are easier to play with, I suspect they'll be similarly the same though. I wonder if 4*16 cl14 is possible? LOL

I don't get this.

Why can't you do more?
When I first start to test to OC my mems I did above 2000 with no problem on FCLK. At first I did have problem to boost my mems so try to Compensate it with higher FCLK
