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

[AlwaysHope]

Yeah, Zen isn't great with RAM OC.

But on the Intel side, almost nothing actually benefits from the faster RAM (i saw plenty of reviews showing that while they can go faster, outside synthetic benches the gains were very small)

But when your an enthusiast, every gain is.... a gain!
Benchmark status is IMPORTANT.
IF was more impactful on Zen+ but the IMC could have been better overall.

I don't think this is a good test. IF can support dram ratios as high as 2.66. It is not a bottleneck.

 

[Taraquin]

I find the Zen 3 chips unimpressive with IF & Ram oc. Is it just me or is the general consensus?
I mean Intel with Z590 boards get up to & over 5000Mhz with ram. For DDR4, that's very good imo.
Such a dilemma going on with upgrading atm. Alder lake & Win 11 with DDR5 bring too much change too soon with new tech. In any case early next month we all will soon know...

You can run 5000 ram at Zen 3 just like with rocket lake, but on Zen 3 inifity fabric maxes out between 1900 and 2100, on Rocket lake between 1800 and 1900, above that fclk 2:1 or Gear 2 is activated.

10th gen Intel or 5xxxG is most impressive ram oc wise. They can both do 4500+ at synced IF\Gear 1.

Alder lake will spin further with the Gear-bullshit which greatly increases latency. Gear 4 is now a thing... I wonder what max clock you can run your ram at in Gear 1? Not surprised if it`s below 6000...

I try today to oc my ram from 3200 to 3600. It's a Samsung b die, I disable xmp put all timings auto rise voltage to 1.45v and let soc and other voltage settings on auto. Computer turn on but don't enter on windows give me a bsod. What I need to do to get this fixed? See what timings it used on auto? Use dram calculator settings and let voltages on auto? Now I revert it with my last settings saved on bios but running at 3200mhz cl16. How I got 3600MHz since it's a Samsung b die its fearly easy?

 

[Mussels]

I've been slowly ticking mine up 1:1 looking for instability (all my old testing was useless, with that burning out PCI-E cable)

Currently at 1866/3733 nice and stable, with my garbage CL18 timings

Doesn't matter if its B-die, you may just be pushing it too hard.

XMP on, then raise it one or two steps at a time

You may need to tune some other voltages etc. You on agesa 1.2.0.3 or later? Try 28-34 procodt, 1.08v soc, 0.98v iod, 0.94v ccd and 0.9v vddp, resistances at 24 20 24 24.

But what I read in almost every site is Samsung b die can run @ 4000 without problems. I will try to change voltages and try to boot with timings on auto or use some guide numbers give in calculator?

I'm in 1.2.0.2 last bios I have before this new beta with 1.2.0.3c.
My ram kit have a version with 3600 @ 18-22-22-42 and 1.35v. Can I use this timmings and voltages give in your advice and ram calculator to try to boot?

And?

It's overclocking. There are no guarantees. Do the work, test it and find the limit. Your CPU or board may hold you back, and you'll never know without actually testing.

You sure they are B-die? 18-22-22 smells like Micron or Hynix. Just try to boot 3600 at those timings, try the voltages I said and set all other timings to auto, don't use ram calc yet. Find highest syable speed first, then tweak timings.

Mine are 3200mhz cl16-18-18-36 b die kit but I will post an ss from thaipoon memory. I will try it tonight now I'm on route to work and don't have time to test it

@Taraquin this is my ram. 3200 cl16 Samsung b die

Thaiphoon sometimes report wrong, and 3200 16-18-18 is very seldom B-die, but you could doba simple test: at 3200 and 1.45V, try running 250tRFC, if it boots and seems stable you have B-die. Non-B-die won't be able to do below 300.

So I think it's not b die because I try that and can't do with 312(number gives in dram calculator) but I try with 1.35v not with 1.45v,but I will try that later

1.35V should be able to boot 312 since it scales with voltage. Try the voltages I suggested and 18-22-22 with rest at auto, try 1.4V on sticks since we dunno whats die it is.

 

[dont whant to set it"']

Can get 3600|1800 with four sticks( single sided ,single rank)( which I also voted in this poll) and also did achieve 4000|2000 with just 2 sticks (single sided,single rank) passing 1 hour occt a while ago on some earlier bios versions released this year .

You have a daisy chain motherboard, you will probably get much further with 2 dual rank sticks

I use your recommendation pc boot enter on windows but after 5seconds bsod. What are your advice more soc voltage?

 

[Taraquin]

Try running infinity fabric at 1800, but ram at 3200. If that works the problem is your ram which is a low end die. You may have Samsung C or E die, they might max out at 3466 or 3533.

 

[dont whant to set it"']

@Taraquin the ram I got listed in pc-specs is double sided and dual rank which I can't seem to get them stable above 2800|1400 on this mb ( last time I tried) , tough on bios versions from last year yes.
While these worked great on b350 and x370 chipsets at 3200|1600 and bench stable 3333|1666 @ cas 16 for both.

That sounds strangly low. With lastest agesa? 1.2.0.3B\C? Remember to use the A2\B2-slots You know what die it is?

 

[dont whant to set it"']

My hynix'es are from 2016/2017 or thereabouts and speced jedec timings pc4-17000(2133MHz equivalent SDR) 1.2Volts.
As for the single ranks , mine are rated PC4-32000(4000MHz equivalent SDR) 1.35Volts maybe ? And made with Samsung B-dies.
Got four of each and the speeds I attained are all using 4 dimms unless otherwise specified.
Le: I am checking at least once a month on average for new bios versions and update the motherboard with these.

 

[Mussels]

I finally bothered trying, raised SoC to 1.15V and DRAM to 1.4V (what i consider 24/7 safe values) and bam, 2000Mhz
Hynix MJR, 2x32GB 3600C18
PBO is off during this test, so 4850MHz CPU limits some results

Damn I really need to try pushing my RAM a bit to see what I can get. 2000Mhz would have been satisfying.
Anyone tried maxing the FlareX 3200Mhz 14CL modules?

Lots of potential here if you wanna tweak secondaries Post your zentimings screenshot if you want input

If it helps my 3200C14 has been to 4400C15, not stable but it’s been there

You are talking about the flareX modules? What is your current set-up with those memory modules if I may ask? I'm going to try to push those a bit to see what I can get. I'm sure there is still some performance left.
