What is your max infinity fabric on ryzen 5000? September 2021 edition

[freeagent]

With my 5900X I get my best latency at 1900 1:1 15-15-15-15-36 2T.. shockingly enough.. 52-53ns. My 3200C14 has been to 4200C14.. something about C14.. doesn't seem to like it anymore.. maybe something with the last couple of AGESA updates? Purely speculation on my part.. Could also be a settings issue, but probably not.. now that I am thinking about it, my 5600X got its lowest latency at 4200C15 lol.. weird eh?

But AIDA isn't telling us the whole story. You need to run things like Super Pi 32m and a couple of others that are bundled with the Benchmate program, as well as Linpack Xtreme.. love dem GFlops...

I got my fastest 32M passes with C14 iirc.

Edit again:

Shite, well call me a liar. I thought that 5900X screen was flat 15s.. if it was it would have been a 53ns-53.4ns pass. With 2T I can lean on TRFC a little harder..

what voltage do you use of dram for these timings, 49 ns thats golden bro 2100 if, wow lucky you

Thanks man, but not what I would call stable, it was 1.6v, and would fail TM5.. If I loosened them up a bit I could probably get them stable. 2100FCLk was not stable either, I can nail down 2000 though. Any more than 2K throw hardware errors pretty much as soon as the system sees any kind of load

 

[JawnyS]

yeah i bet with 1.6 volt it gets to hot to be stable, im at 1.49 with my timing and while gaming its between 45-50 degrees my ram and it stays stable, hcl mem test pass 400 % but i cant get my latency below 55ns, im gonna try to fiddle around with cr2 instead of 1 with gdm on

 

[Cowboystrekk]

whats is your latency on aida with 4000cl16, im at 55 ns to 55.4 ns, depending on the run, but for me 4000mhz wont work somehow even 3933. i know my cpu can do it, and this ram kit is xmp 4000cl16. on my x570 steellegend i was able to get another kit stable at 3933 cl 16, but on the hero wifi i cant, anything over 3800 gets me a super slow boot

Around 52ns.

My memory has never seen 45-50 before. I try not to let them go over 35.

 

[DLD]

Bumped up to 4000 / 2000. Got an error after 10 min in Karhu so bumped up the voltage slightly to 1.465 an let it run again. Would be nice if I can get this 100% stable

 

[freeagent]

You are being a little soft on the SOC, give it moar

Maybe try 1.156 with lvl3 llc

 

[DLD]

Ran Karhu for an hour without an error, but getting a lot of WHEA errors now. That was at 1.47v.

how can you achieve such low temps with 1.6 on dram... my cpu and gpu are watercooled custom loops i have good airflow in my case and in warzone my ram temp is 45 degrees at 1.49 volt

 

[freeagent]

Define good airflow.. are we talking 50cfm? Less? I’m a little above that.. there should be roughly 400cfm flowing through my case when shit gets real..

 

[DLD]

Set my IF back to 1900 and left RAM at 2000mhz and now there are no WHEA errors. So it seems my CPU doesn't like 2000 IF

freeagent has a lot of air moving through his case. And I mean, a LOT. It's like the bypass chamber in a turbofan in there I have my CPU and GPU in the loop and I'm at about 46 max in the most demanding games I have (currently that would be a tie between MW2019, Halo Infinite, and Borderlands 3).

The threshold for Bdie thermally destabilizing is different for everyone. Mine is 50C, so as long as I stay below that I'm fine.

 

[freeagent]

Now that my fans are on a controller it is so much nicer! My CPU fan is a TY-143 that revs to 2500, and my front intakes are 2x 140mm iPPC 3K, the rear exhaust is a 120mm iPPC 3K, and I also have a 140mm TL-D14X in the basement that revs to only 1800 I think.. but now they all run together lol.. before they were all over the place I had to tune them all individually if I didn’t want them revving to 3K. Which I don’t

My Meshify C is sealed at the top, and no pci covers.. she flows

stable like that (3800CL14);

i got no problems booting into windows at IF 2000 on 5900x
Soc at 1.13v vddg and vddp at 0,9v IOD at 1,05v
Prime Large FFT and MSI Kombustor to get mixed load Running without at problem no crashes, but i get frequently about 101 whea erros once every 5min
is this save to run, does anyone having experience running your PC with those errors popin up but having a stable system?

edit whea starts already directly at 1933mhz and practically no change on error count till 2000mhz.

@poisxpto
nice, whats your ram Voltage running like this. My b Die will do cl14 at 3800mhz only at 1,58v, did u chance ProcODT by yourself down to 36.9?

1.5 ram voltage.
for ProcODT i didnt change, it was auto. should i change ?

no leave it as it is, mine is set to 48.0ohm on auto and i cant get even close to your timings with my trident neo z 3600cl16 b die kit its dual rank 2x16gb)
whats the kit u own exactly?

Seems like there is a lot of variation between CPUs. Me and 2 friends have tested 3 5600X now:
Mine: 4133/2066 max, no WHEA 19, CO runs all cores at - 30 up to +50 pbo.
Friend 1: 3733/1866 max, loads of WHEA 19 at 3800/1900 or higher, CO -12, -15, -21, -26, -30, -30.
Friend 2: 380/1900 max, loads of WHEA 19 above. He has nit tried CO yet.

I use at 2 dimm mATX so that might explain no WHEA 19s vs the 2 others who has fullsize B450 and B550. All if us have Agesa 1.2.0.3.

My CPU and IOD seems close to golden sample, friend no 1 has a turd CPU and a bit below avg IO-die, no 2 we don't know CPU quality yet, but IO seems avg.

So theres another thread with some nice opensource little programs that allow editing and writing XMP values right onto your memory

Creating custom XMP profile for DDR4 | TechPowerUp Forums


It works.
The custom values we worked out in this thread many pages back, are now saved into my previously empty XMP2 slot.

Would be awesome if you found a stable, fast profile with your wanted tweaks and saved it. My RAM unfortunately already has 2 profiles. DDR5 comes with 4 profiles I think, lots of room for tweaking there

Everything saves except TRFC for some reason

That said, having a 3800 profile built in is freaking awesome

 

[freeagent]

I think she is stable.. I have other shots but OCCT is good enough for now

1.55v on the stix.

This one I let her boost:

Hey Guys!

First of all thanks for the messages on this Thread. Most of them helped me stabilize my set up
I have attached the image of how it is right now. Still think there is room to improve my timings to achieve better latency on memory (was getting 53.7 nanoseconds running Aida64 in Safe Mode).

In summary: happy with the results, but would highly appreciate your expert tips

Lots of Love
