r3900x and Memory clock speeds

[tythelion]

so in my build i have r3900x and 32gb (4x8) of corsair vengeance RBG's at 3200mhz

for about a week after installing and getting everything going, i was hit with weird ass crashes. and with a week of going through multiple dmp files, googling everything i could i traced it back to my memory. 

oh great, dead ram stick gonna rma newegg this cause thats always really fun. 
swapping sticks

all sticks work.

is it my mobo channels?

try all sorts of different configs 

all work

well duh i'm stupid i should have just ran memtest 

memtest fails before the 7th test maxes out on failures.

sweet bad mobo.

out of curiosity i go to the r3900x wiki page. and i find this (down below), telling me it can only run 4dimms at 2933 or lower

confused, i just throttle my ram and away we go

fast forward about 6 weeks to today and i watch this sneaky video (all crash free btw)

https://www.youtube.com/watch?v=sa8eqMFIHVE

 

What i wanna know is

did i go the cheap way and just throttle my ram (not that it really matters i'm not going to tell the difference with 200mhz difference in speed)

am i just nooby?

or is there a way to run it at 3200?

or did both linus and I buy some speedy ram that this chip can't handle?

That's the spec by AMD. More than that is considered overclocking and AMD is not responsible for crashes beyond that.

so me being able to successfully run at higher than recommended speeds is simply my fault? 

so how can i get my ram to run at advertised speeds

1.1V SOC voltage, up to 1.45V memory voltage could help stabilize things

SoC is at 1.1v and i've tried mem at 1.35 1.4 1.45 and 1.5v the lower voltages crash within 10 or so minutes with higher voltages only crashing when it is under load

Well if it is you being nooby then you are not alone.

 

As soon as I enable XMP I get multiple mem relatable and random blue screens.

What I have is Corsair Vengeance 4x8GB 3200Mhz ( CMK16GX4M2B3200C16(R) )

Unless I am mistaken the same as yours but without rgb.

 

I'm guessing it's the dimms themselves. And yeah it really sucks that when you check the Gigabyte memory supported list they are marked as supported on 4x 3200.

yeah the same just less cool

yeah the xmp is a no go i just manually clocked the mem at 2933 in bios and i've been fine since

I've had this exact same issue with my Ryzen 1600.

 

I've got a G.Skill Ripjaws 16gb 2x8GB (16GB) 3200mhz kit. If I try to use the XMP profile, I'll get random crashes and blue screens.

 

So far, I've only got it to work when I manually set it to 2933mhz. 

[Mark Kaine]

Yeah, I was considering this or a similar board until I read about the restrictions it applies in certain cases (ie using the hardware as its intended) 

That was that with "Auros and me"

 

Meanwhile I'm running on my old MSI B350M,  3200 Corsair RAM @ 3200 MHz... and I'm actually thinking of OC to 3400 or so... 

 

 

Also AMD recommends minimum 3000 for Ryzen,  2933≠3000 ! 

 

I'd try returning the mobo,  also seems strange to blame the RAM when it's the mobos fault - imho!!! 

 

@Xiee what mobo do you have? 

 

And are you sure you selected the right XMP profile? Usually it's XMP2,  not necessarily,  but in most cases. 

My B350 also had two different profiles before I updated the BIOS,  when I tried XMP1  the PC would immediately crash... XMP2 no issues.  Now with updated BIOS, both profiles are the same so I don't think it would make a difference,  I'm still using XMP2 though,  just to be safe

i'm not a bench master, so a lower mem speed will not affect me but tearing out all my rgb, my aio etc to return a mobo whose only limitation is not letting me run a 200mhz faster memory speed will. Its running fine now. but with jurrino's volt suggestions and my own trouble shooting i couldn't get my ram to run at advertised speeds without crashing, i'm just curious if someone else is having to throttle their ram or if linus got it to run at 3600 through some voodoo magic

did you try messing with voltage? cause according to the same wiki you're only able to run at 2666 according to amd

Fair enough.  I was just pointing out 3000 is the absolute minimum AMD recommends and it's kinda hilarious they sell these boards with said limitations when they are designed to run with the newest Ryzen gen in mind... 

 

As for the "Voodoo magic", possibly,  you can tune up RAM,  but it's very complicated doing it manually so I'm not surprised some people got it to work despite the limitations some manufacturers put on their "Ryzen boards".

Then it's the wrong RAM or motherboard,  AMD recommends at least 3000MHz DDR4 dual channel RAM for their Ryzen line up.

i'm just regurgitating what wikichip says 

https://en.wikichip.org/wiki/amd/ryzen_9/3900x

https://en.wikichip.org/wiki/amd/ryzen_5/1600

[Mark Kaine]

Seems kinda irrelevant and possibly incorrect.  There are plenty of board and RAM combinations that can run over 4000MHz,  whereby around 3600MHz is the "sweet spot" according to many tests. 

 

 

I think I just don't get the subject? 

 

Yes you can run RAM at the advertised speeds with *automatic* settings. 

 

If that doesn't work it's either user error or the wrong hardware.  Wiki is irrelevant on that matter. 

 

And yes,  with the right hardware and knowledge you can OC RAM quite a bit. 

 

Again not seeing how wiki is relevant on that subject,  there are RAM calculators for this stuff which will be probably a lot more helpful in that regard.

There are usually two XMP profiles which of one will *not* work without some tinkering.

Again, AMD recommends 3000MHz minimum so I'm not seeing how this can be true,  maybe I'm wrong,  please provide the link from AMD,  thanks.

What board is that? It could be a bad board design or individual memory controller that just doesnt like out of spec frequency with 4 sticks. Btw 2 sticks sometimes solves the problem

I remember reading all that from launch press releases. Anyway Asrock is the only one that puts this table into their boards' pages. Mot sure if it's in the CPU's users manual, but I've seen the same thing for Zen and Zen+ so it doesnt surprise me

This board's design isnt the culprit then

[GamerDude]

I'm running a 3900X + GB X570 Aorus Xtreme, 4x XPG D60G DDR4 3200 RAM is set to 3334Mhz (I believe I had XMP set in BIOS, though I ain't sure now as I've just flashed my BIOS to the latest AGESA 1.0.0.4 F10a BIOS) and manually OC'ed it to 4.475Mhz at 1.375v. I don't recall getting BSOD or whatnot even when I fist got my board when I enabled XMP profile. OP has the Aorus Master which should perform close to mine....

i never got bsods with my crashes. Just a black screen and fan cycles. at first i thought it was a gpu issue

AMD 3900x, Corsair Vengeance 4x8GB 3200Mhz ( CMK16GX4M2B3200C16(R) ), Radeon VII, Gigabyte 570 Master (1.0)

I have XMP disabled and enabled. When it's enabled I have 3 different levels I can use. None are stable.

 

I ended up with 2 single and 2 double dimms. It sounds like to me that I need to set it manual a bit lower than 3200 or get different dimms.

You need to check if this RAM is on the recommended vendor list of your mobos manufacturer - I think it should be because that's a really common brand... 

 

Maybe you mixed the sticks up somehow,  since you have several - never do that,  sticks are always tested to work together as a pair and mixing them with others might result in irregularities. 

 

Otherwise, there really shouldn't be a problem to run RAM at its advertised speeds,  it's a simple 1 click solution nowadays. 

 

 

What's kinda remarkable, since there are so many threads with similar issues,  I've noticed it's usually the x570 boards,  and more often than not Gigabyte... 

 

I've just never came across this particular issue outside of this forum,  usually the correct XMP profile just works, unless there's an actual hardware defect.

They are on gigabyte's memory supported list and rated at 3200 with single and dual x4

On paper I should be able to turn on XMP and forget about it, in practice, it is running stable for 5 or so hours now at 2933. 3200  ( XMP enabled ) is BSOD's within the hour.

 

The memory are in the rights slots pared with the same ones.   It's just that 1 pair is single rank and the other pair is dual rank.  ( samsung vs SK hynix ) The only reason I got 2 different ones was because I wanted 2 red ones and 2 black ones. I did not realize that even though they have the same part number, it comes from 2 different factories...sigh...

On my intel 6700k this was never a problem ><

 

I'm thinking about just getting 2x 16gb at 3600 and be done with it. It's less of a headache.
