Ram Help

[xBluemist]

I have 2 sticks of 8gbs of ddr4 ram, and a Strix b550, and a ryzen 7 5800x, but its defaulted to 2133 or something around that. Ive gone into the bios and when i enable DOCP, and then boot, it restarts, tries to start about 3 times, then runs in safe mode and i have to reset it back to default. Is this a power supply issue? if so i have a 650w evga bronze rated PSU. here are my specs just incase

 

B550-F Strix mobo nonWIFI

Ryzen 7 5800x

3600mhz trident Z neo 16 CAS

NZXT Kraken x63

Strix 1070ti

 

If you know the issue, please let me know, it would be greatly appreciated

 

Have a blessed day!

Try each stick individually, mayhaps? Rule out part failure.

Sorry im new to PC's. What do you mean exactly? like only running one stick of ram?

Yes, so run just one stick of RAM - see if this will allow you to increase the RAM's clock speed. DOCP should be picking up the proper speed if I'm not mistaken, although my RAM doesn't support it. Do this for both of them. Your other option is to manually set your timings and voltage.

Yes, try with one stick to see if it works, then try with the other.

 

If one of the two RAM sticks can't run at 3600 CL16, then the pair together won't work either. If they both work individually, then you've ruled out a bad stick of RAM.

Yes. Its possible one of the sticks is bad (if you try 1 at a time and it won't work with only 1 of them...), or if it won't work with either of them, its possible your CPU's memory controller just can't run RAM that fast. 3600 should be easy, but its possible.....

I also know that my Strix can be picky about which rank you use. Which slots have you installed your RAM in?

5800X can run 3600 and more. This is only plausible in the event of a toasted memory controller, but this would present in much worse ways I would think.

Not necessarily. The official spec is 3200, so a CPU will pass validation without confirming that it supports 3600. It could just be a case of losing the silicon lottery

3200 being "official" is the CPU's default. DOCP will override that. RAM speed capabilities are determined at the motherboard level.

This ^.

 

99%+ likely run 3600, but, its not guaranteed to..... It is possible it can't do it. Wouldn't be the first time, and won't be the last. It is rare but not impossible.

slots 1 and 3

Try slots 2 and 4 as well. My board gave me fits about this earlier today while testing used RAM for a friend.

Worth noting that our boards are nearly identical.

Yes, but the IMC is only validated to 3200.... The mobo can do well over that, but the IMC may not be able to. So overriding it in BIOS is causing a situation the CPU can't support. Potentially... still not sure of the issue, but this could be what is happening. Testing 1 stick at a time and trying some different speeds will help us understand.

The memory controller is on the CPU. Just because you set the speed in the BIOS, that doesn't mean the CPU can run it

What does this have to do with anything..?

 

Sorry, not being rude or like offensive but the reason 3600 is "the right" speed for Zen 3 is because you can run the flock at 1:1, faster will cause it to not be 1:1 and why it doesn't help and may hurt. But that also doesn't mean it will work at 3600, its only guaranteed to work at 3200 or lower.

You're not offending me. We're having a reasonable discussion here. My understanding as conveyed to me by my brother (software engineer at Microsoft) is different here. Furthermore, everything I'm finding on the internet (for both him and myself, I've been trying to pick a RAM upgrade for my own Ryzen for a while now, been reading into this a lot lately) seems to come to the conclusion that 3600 is about where you'll run into diminishing returns on a Ryzen 3000 or 5000 and that you want to opt for a minimum CAS latency of 18 in that scenario. I'm absolutely positive that we can get this fella's ram running faster for him.

and you are absolutely correct sir. simply slot 1 and 3 are just funky. I respect you dearly.

3600 is where you hit diminishing returns, yes. If it makes you feel any better. I am an engineer as well.

 

You hit diminishing returns because of the Fclock no longer being 1:1 above 3600, that is why 3600 is the sweet spot. But that does not mean it will actually run at 3600. The IMC (integrated memory controller) inside the CPU is only engineered to run at 3200. Anything faster is an overclock. 

 

Most things do overclock, but they are not guaranteed to.... Or sometimes need a little push to get there. OP may need to up his (whatever they are equivalent to on AMD, I am more of an intel user) IO and system agent voltage. Those (on intel) can help increase memory stability, and more isn't always better, sometimes less is better - weird I know.

 

So it likely *will* get to 3600, but its not guaranteed to, and just hitting DOCP may not do it due to this. May need to enable DOCP AND pump the IO and SA voltages a bit. Or even potentially vcore a bit. Remember, this is an overclock, it isn't guaranteed to work.

Not a problem! More than happy to help. If you have any further issues, let me know!

Glad that seems to have worked! But that doesn't reduce the value in fully understanding the system

 

Its still an overclock, and that means its not guaranteed.

Well im going to take it as it is and see it as that im in better standings from where i was before. Thank you for your help aswell.

It could also be a B550 chipset and throwing a fit over which RAM slots are used which is common and I nailed it pretty quickly here, but I do appreciate what you have to say and will do further reading on the subject.
