Ram Not running at 3000mhz?

[LamoidZombieDog]

Why does my bios show my ram running at way less then the 3000mhz its Supposed to be? i hajd this issue with my 2x8gb g.skill ddr4 and my current setup of 2x8gb and 2x4gb ddr4 3000mhz

Have you enabled XMP?

let me check. i believe so

[Elisis]

Where are you reading the speed it's running at from?

 

Edit: Nevermind, reread. What are you seeing in Windows?

[Tristerin]

Full specs?

 

If your board only supports X frequency speed, and your CPU memory controller only supports X frequency speed - you may not have posted at all even if you enable XMP.  Which would then cause the PC to boot only with very loose timings and low frequency to guarantee stability.

my board is an Asus Prime b-350 Plus Motherboard

Enable XMP, A-XMP, whatever. Alternatively, manually set your RAM frequency and give it 1.35v DIMM

[Tristerin]

Board supports up to 3200mhz

 

What CPU?  I have the same board on a R7 1700 @ 3200mhz memory but it was a bitch to get stable enough - even then it can crash 1 time a week or more.

 

The CPU memory controller matters next - if its Generation 1 - good luck getting stable over 2666mhz with XMP, based on my experiences (getting 100% stable)

 

BTW you likely failed XMP BIOS setting and it dropped to 2133mhz (DDR stands for double data rate so 1064x2)

I can't find XMP anywhere. The memory is set to 3000mhz but says it's running at 2133

Asus boards call it DOCP iirc.

Only guaranteed for 2666mhz due to the CPU memory controller.  Couple options here:

 

1.) Manually set to 2666mhz and it will post, see if you like the results and leave as is (Ive done extensive testing on first gen ryzen)

 

2.) Manually set to (insert any frequency you want to try in the list on your BIOS) and see if it will post, don't worry about timings as first gen doesn't give a crap about them compared to frequency).  I suggest then running Cinebench R20 and if it passes, Firestrike.  Then if you can run 10 minutes or so of Prime 95 I call that stable AF.  You will have to learn how to OC memory if you want to push your chip, its how I had to do it all trial and error.

 

3.) Download AMD Ryzen DRAM Calculator and check out its recommendations on settings based on your hardware, insert those into your BIOS and see if it posts.

 

4.) Run Benchmarks (CineR20, Firestrike, Prime95 all free) for each, if it passes all 3 call it stable and try for faster or work on timings.

 

5.) Don't focus on timings, frequency is king with this generation

 

6.) Frequency wont change your CineR20 results at ALL.  2133mhz CL14 vs 3600mhz CL18 is the same score within margin of error.

 

If I think of anything else Ill post, if not ask away!

Correct on that board

It posts fine before. If I set it to 2666 would it be faster, and in that case better then what ever it randomly sets to? When I rebuild my pc I'd love to upgrade my ryzen when I upgrade my board so maybe that will fix ram issues.

It posts just fine at 2133mhz because that's the base "anything will work here" frequency (basically).  Your memory, however is capable of higher, which first gen Ryzen literally cannot breath without (two things, dual channel memory which is two sticks, and highest frequency possible.  Without that its basically choking itself but cant go to full blastoff if you know what I mean).  Right now its doing what its supposed to (randomly set to) because its unstable at your XMP/DOHCP profile because the CPU itself isn't made to run that high.

 

You can get it to run higher, and at 2666mhz manually set it will post (all three - the board, cpu and memory are fully compatible at that frequency) and there are gains to be had (explained below).  Both of my rigs when I competitively gameplay I set at 2666mhz to GAURANTEE stability.  When Im playing a beautiful "basic white girl" game I set to as high as possible (see my Firestrike scores in my sig on first gen Ryzen...3200 and 3600mhz stable on two diff boards) because of the (explained below).

 

Due to the (RAM) connection with the Infinity Fabric in the CPU it will communicate at a much faster rate with higher frequency (think of it as running at 2.1ghz instead of 2.6 or 3.0ghz) which from all of my testing is:

 

Depending on the title, the difference from 2133mhz and 2666mhz at all max settings is either unplayable to playable (online mode BF5 for example) in FPS (all settings maxed out)

You will result in MUCH tighter frame rates across the board, with higher frequency - I.E. if you get between 100-120 FPS in a game you will likely see 110-125 average FPS or better)

 

So, push it to 2666mhz in BIOS at a minimum of you aren't letting it breathe, basically.

 

Also - upgrading your board wont achieve anything other than maybe better ability to overclock the CPU - that's it.  (depending on what your use case is - gaming, no wont help).  I haven't looked into it but that board likely supports Zen2 with a BIOS update already if you wanted a CPU upgrade.  Ive found that with a solid overclock (I can get 3.8ghz stable on my ASUS Prime board at stock voltages on my 1700) I compete handily already with Zen2 in benchmarks.

From what im hearing on my other post is the 2133 it says it's running at is the 3000mhz and is normal. It seems to be running at 2133mhz right now with no issue.

I don't think you are understanding.  It will run.  Sure - it may even be acceptable to you and not have any issues - its not supposed to at that frequency.  That's why it posted (booted up) to that frequency.  It works.  

 

What I am trying to tell you (and Im kind of done at this point unless you are interested in OCing the ram correctly, Im more than happy being helpful but convincing you is not what Im here to do) is that if you set it faster - you will get more gainz from your PC bro.  Or don't, Im not sure I care lol.

 

OR what you mean is that on CPU-Z when you are in Windows is showing 1500mhz, which is 3000mhz at Double Data Rate - which is it?  (EDIT - and if that's the case why are you asking again in another post - in this one it seems you are asking why its running at 2133mhz and why not 3000mhz  if you mean just in BIOS only and its already answered in another post Im not sure why we are wasting our time here).

I've set it and this is what it's running at according to cpuZ

2133mhz CL15

 

If you set DOCP/XMP in BIOS and it didn't "take" than it automatically downclocks the memory to an acceptable general frequency, which would be whats happened here IF you have tried to set DOCP.  If you haven't ever done that, than this is just the basic setting its running at UNTIL you do that in BIOS.

Have you tried the DOCP settings?

Have you tried setting to 2666mhz in BIOS manually and changing nothing else?

 

EDIT - 24gb is an odd config - did you add another kit of memory (I.E. 8+8+4+4?)?  Ive got a 2x8 2133mhz CL14 and a 2x8 3600mhz CL18 kit working together at 2666mhz CL18 for memory intensive gaming Im playing atm so you can get the kits to play decently together for improved performance over 2133mhz if so.
