Is't that a bit high? I though you needed that for over 3600MHz.

Eh... 1.15v is a little up there. Nothing too unreasonable. I know b-die will typically boot 3600 at 1.15 with the proper timings, but other modules may differ. With my micron I needed that to boot 3000 lol.

And actually, I'm looking at printouts I generated with the calculator and it is calling for SOC max as high as 1.175 for b-die to run 3600.

Though I guess it's also worth saying that 3400/CL16 is currently working for my b-die with SOC @ 1.125V.

I know the deal, I'll look into it when I get the time. Can't be bothered for now the thing flies anyway. The most impressive thing is the power consumption and the temps, under load with my Katana 4 it barely gets to mid 50s. When I was gaming or something of the sort it was like sitting next to a furnace with my old FX 6300.

Definitely, that's the first thing I noticed when I first dropped in my 2600. Even with the stock fan and running the stock boost, it was pretty fast and efficient. Took a lot to get that little fan turning. I think that's where they really shine. As much as I like to overclock I always recommend people try running their Zen and Zen+ chips stock first, because they're so well balanced that if you choose the right one, you might not need to OC at all and can instead take full advantage of those really low base TDP's. I would never tell anyone to not do that if they're considering it. That's part of the money's worth!

And yes, night and day from an FX 6300, in so so many ways

Thanks for those tips about SoC, haven't played with it much yet using the new 16GB kit of Team Dark Pro I got now. Still refining Tras & Trc atm with memtest64 running. But yeah, a lot to explore with this DDR4 Overclocking.

 

[Mussels]

For comparison when my board was new i needed 1.15V to get 2667Mhz stable, now i can do 3400Mhz with 1.10V

These AGESA updates make a massive difference

Hey man, don't take my word for it! I can only speak to what works for me with my RAM and mobo. You have a 400-series while I have an x370. Might be different for all I know.

Honestly I really do recommend playing with the Ryzen DRAM Timing Calculator. I'm finding that it's such an indispensable tool. Though even if you don't, there's an interesting little logic plot included that's actually very revealing and helpful for working out stable overclocks. It definitely clarified a few things for me about how certain things are related... ...like how if CPU voltage is too low, sometimes the memory will take a dump, even if the voltage is actually enough for the CPU itself. This plot reflects that, among many other relationships between different settings and different types of issues. Good for working out when, why, and how to change what.

Oh now your complicating it...lol...
Missed you got X370, lots of info on it over here though Link

LOL it just is complicated man! I'm telling you I have a decent mobo and a really good set of RAM and it's still not drop and go, heh. It really, really pays more and more the deeper you go. Whether you have the fastest RAM or not, there are many hidden gains to be had if you're willing to go through the tedium. The hard part is getting organized and working up that routine. It's the same as overclocking your CPU, only with more conditions and possibilities.

Like I don't disagree with you at all. I am a super nitty-gritty, get-down-to-it kind of person... ...just naturally on adderall. I love to split hairs. But even for me, it's a lot. There is something oddly satisfying about it, though. So much to unlock and unravel.

And thank you, I am still working my way through that thread lol. I intend to read all of it

First BIOS I needed 1,10v SoC to get 3133, now I'm at 1v for 3333. "Fine Wine" meme?

Just to be clear, that's with the system in your System Specs?

Yup. Cheapest out here.

@Vya Domus Ryzen is super picky about timings. Standard XMP profiles and auto settings just dont work. Not for me anyway. I've never seen anything this picky. Hopefully this gets sorted one day.

You could always try the Ryzen DRAM Calculator. It works with a lot of different types of RAM. On that page youll find instructions on how to see what manufacturer and die your DRAM actually is and get your latencies for the calculator. May still squeeze a lil more out, even if it's not b-die.

I read that a lot, but so far the only trouble I had with Ryzen and RAM was the lack of motherboard settings from MSI. Until recently it did not allow any subtiming control.
BUT I had my 1800x nearly since day one and my board came with the very first bios and AGESA, I could plug my ram in and enable XMP - done. No issue. Now this year I went over to threadripper and instead of B-die I got Hynix memory, but the same deal. Plug and play with XMP. Only OC past the XMP setting is a bit tricky on the hynix. Voltage doesn´t seem to help much.
My 1800x on B-die however works like a charm. SoC 1.075V, DRAM 1.36V, 3200MHz CL-14-13-13. With 1.45V I can either get a little bit tighter main timings or higher frequency.

Bios-Updates on the X370 didn´t change anything for me, but on the X399 the latest updates made it even more difficult to get OC further then XMP-settings. With the earliest bios I could run my 2933 quad kit @ 3066 and slightly better timings then XMP, but with the latest AGESA I can no longer get above 3000.

Man... I don't know if you're lucky, or not! Sounds like you got a pretty good set of b-die though! I'm jealous. Don't think I'll quite get there on this board. Probably gonna try for 3600 CL16 and then maybe take it up a little more with BCLK nonsense. I'm having pretty good luck getting speed up a little more without messing with timings via a little BCLK boost and CPU multiplier decrease.

And yeah, BIOS updates haven't made a huge difference on my X370, either. It's always been solid. Though those are more mature than the 400-series boards and have been for a while, so memory issues should've long since been ironed out.

Come to think of it Ryzen 2 owners should have an easier time in general. It was Ryzen 1 that used to have all of those issues with crazy latency/slow ram speed, ram incompatibility, etc. But I remember that being fixed a long time ago. Anybody running on established hardware should have access to as much potential as they're gonna, especially on Ryzen 2. I'd imagine only those on the new X399 and 400-series boards would have issues. And even then, we should be hitting a point where that stuff is fixed... ...I'd hope :/

Just realized I made a MISTAKE up there. I said 1.25 SOC, which is ridiculous. What I meant was 1.125

 

[biffzinker]

Been tempted to try the Ryzen 3 1200 I still have since the minor incompatiblity issue I ran into with the Teamgroup 8GB kit. Wonder if I could get a better Oc than 3,825 MHz with the PNY kit. Could also try out the 2600X stock cooler.

Not making much headway with my RAM. Beware the 3600/CL17 8GB b-die kits from Gskill. It's still b-die so it's still a great performer, but compared to the 3200/CL14 and 3600/CL15, it's not nearly as fast. I'm pretty much hitting a wall at 3466/CL16. Timings really don't like going much lower than that, even at 3200, it's CL15. I knew it cost a little less for a reason...

This is 1.41v DRAM and 1.1125 SoC. Maybe with much more voltage and a ton more messing around I can squeeze out 3600 at CL16, or something like it. But honestly on this setup I doubt it's even possible to get it stable past that speed.

I also discovered that my mobo doesn't have the new AGESA bios update available yet... ...I was an update behind when the new one came out, so I thought I had the new one when really I had only just gotten 1.0.0.2.

I shouldn't bitch, still beats my old 2x4GB micron kit running at 3000 CL18. Even the worst b-die is the worst of the best

 

[Mussels]

pretty sure i read that after a certain Mhz (3200?) ryzen only runs on even numbers for the timings, so that might be why you're having issues there

 

[Vya Domus]

So apparently the kit I have is indeed B-die but from Micron. Still no dice, nothing works above 2400mhz, I'm starting to believe the board itself might not be that brilliant.

 

[Mussels]

And here i am with hynix C-Die, but doing alright :/

What SoC voltage are you running? latest BIOS?

 

[lexluthermiester]

pretty sure i read that after a certain Mhz (3200?) ryzen only runs on even numbers for the timings, so that might be why you're having issues there

I've read this as well, but I've seen different. Not sure if such is set in stone.

 

[Vya Domus]

1.125 for SoC

The thing is the Ryzen DRAM calculator seems awfully optimistic about timings, for example CL14 for 3000Mhz seems really unlikely to happen given my kit is meant to run at CL16 at that frequency.

Got a feeling this isn't really Micron B-die but something else.

 

[Mussels]

find looser timing combos from your same RAM type, try lower voltages as well as higher
try different ram slots - on my board i have to use the pair that starts away from the CPU, not closest to it
If your board was the same as mine, it'd be the ones with the red lines here (if thats where yours are now, change and try the other pair)

 

[Vya Domus]

Changed the slots and no difference. What's baffling is that 2866 is the only frequency under which I have been able to get past POST but not Windows. Anything between 2866 and 2400, nothing wont even POST.

 

[GoldenX]

Damn, well, wait for a new BIOS?
If you happen to come to the Patagonia, bring the sticks and we'll try them on my motherboard.

 

[robot zombie]

Oh I know. Im shooting for even timings. When I say CL17/3600 or CL15/3200 im referring to grades of b-die. Those are advertised timings.

I've read this as well, but I've seen different. Not sure if such is set in stone.

I'm pretty sure it is. No real answers beyond "thats just how ryzens supposed to work" as far as Ive seen. For me it kinda sucks because b-die can usually run cas a point lower than the other primaries. Thats how my sticks are specced. Ill double check when i get home but Im pretty sure its still gonna round up.

Check for memory presets in the memory section, not sure the Strix has them but can't see why they wouldn't. The Stilts for "B" die work quite well. You're right in saying XMP(for Intel) and auto don't always work well with (Intel) sticks like you have but I have the same ram and they'll run 3200 Cl14 just fine. Just needs the proper timings.
@Mussels
You can set odd timings over 2933 that's what the gear down setting is for in memory timings. But AMD does "default" to an even CAS number

Odd, I have Micron H-die (Crucial value RAM) and it clocked all the way to 3200 with 16-17-16-16 timings. This is from a module that is rated for 2400 17-17-17-17. RAM voltage is 1.3V. My Gigabyte mobo overvolts SOC voltage a bit to around 1.187-1.2V. People have better success with higher SOC voltage and manual RAM timings instead of using XMP profiles.
