RAM not matching rated speed

[Butch00]

So, first off system specs:

 

CPU: Ryzen 7 2700

Mobo: ROG Strix B450-F

RAM: 32GB G.Skill Trident Z RGB 3000MHz

GPU: 2070 Super

 

I recently bought Red Dead 2, and I just let Nvidia choose the settings for the game. I noticed my FPS was usually between 50-60 with pretty frequent drops into the 40s. I play at 1080p, yes I know a 2070 super is overkill for that resolution, I try to play everything at high refresh rates if possible. Just to test it out, I lowered all in game settings to their absolute lowest settings, and I was still barely getting 80 FPS. I started looking around just to see what might have caused it, and I noticed my RAM speed in windows was only 1367MHz. I went to my BIOS and it shows in there as 2133MHz, better, but still lower than it should. Any attempts I make to change my RAM speed to 3000MHz or above will cause the system to boot loop until I reset the CMOS. The highest stable speed I found was 2733MHz, and even then windows doesn't detect it properly. I know RAM speed can make a pretty big difference with Ryzen, but im pretty confused why its running so much lower.

In windows you are looking at the speed cut in half because its DDR (Double Data Rate) so effectively it was 1367 times 2 = 2734mhz.  

 

When you set the ram speed in BIOS did you set the DOCP/XMP Profile or just set the ram to 3000mhz which would then not properly overlock it like the DOCP/XMP profile requires (voltage etc).  Also your CPUs memory controller max guarantees support up to 2933mhz anything over that is luck of the draw or you have to manually tighten down the overclock settings.

I... think I might actually know this one, only because I’ve read answers to similar things here...  I’m going with “Because you reset the cmos.  It went back to default.  Got to go back into bios and set the speed again.”  Kinda curious if it’s correct or not.

Feels bad man....

Another AMD RAM compatibility issue, this has become a plague...

Aye Matey. 

Tiss a plague of large magnitude. 

Budget memory on picky Zen+ memory controller.

 

No help available overclocking ghost sticks. No specs = at a loss.

I can set the speed back, but anything over 2733MHz will not allow the system to post unfortunately.

So is this more of an issue with the RAM? If I was to go out and buy a different kit of ram is there a chance I can get higher speeds or is it a memory controller issue and I'm screwed pretty much?

Thanks for the clarification on the speed with Windows, I never bothered to look that up before, I have tried to just set the DOCP profile, I have tried to manually adjust it, and I have tried both. Regardless of how I try to configure it I can only get 2733, anything above will not post.

So not correct.  Good to know.  Thanks

Is your BIOS up to date?

It's more the later the Cpu IMC is an issue. 

Doesn't like odd timings. Doesn't like a lot of memory (more than 16GB)

 

Yours will probably do 3000mhz, you just haven't figured out how to do it yet.

 

Use Typhoon Burner to show the specs of the memory modules.

I thought I was, but it looks like there have been a few updates recently, one of them for memory overclocking, and just general compatibility issues, I'll update that and see what happens

I'll take a look at that and mess with it

So your board supports your ram no problem (speeds wise) - your CPU supports up to 2933mhz (board and CPU have memory controllers).

 

As for ram compatibility that will be solved with the BIOS update.  I highly suggest you do that first as its the next real "gate" you have to get through to ensure stability either way.

I've updated the BIOS to the newest version, unfortunately no change. I even tried going in and adjusting the memory timing, and raising the voltage, and the system will still not boot past 2733MHz

2x16gb sticks or 4x8gb RAM sticks?  If 2x16gb are you populating the correct slots?

Didn't even think to check that, it looks like they were in slot 1 and 3, the manual says 2 and 4. Just like that I can hit 3000 , and it even gets detected in widows properly. I guess it pays to read the manual and not just assume, thank you so much!

Woooooooooooooooooo!  Glad its working!  Enjoy!

The ram is suppose to run at 3000 MHz as long as it’s in the proper pair of slots. It doesn’t matter if it’s 1,3 or 2,4. Are you planning to upgrade your ram in the future, no then your system should be fine. Yes then, there be some fault in the memory controller that’s on your cpu. For future ram troubleshooting, remove cpu then reinstall or check the cpu fan, under tightening over tightening can cause problems too.

I don't plan to upgrade, I thought it was odd but I'm just happy it worked,  next time I upgrade I'll probably be getting a new board, CPU and faster RAM
