RAM won't work on the DOCP profile

[HeyImFade]

Hi!

 

I'm still new to PC building somewhat and have my thoughts of what would be causing this issue but I know y'all are way smarter so wanted to see what y'all think. I used to run 2x8gb sticks of memory in the higher priority slots and when I ran it on the DOCP profile at the advertised and preset 4400mhz it worked fine no issues but when I wanted to upgrade to 32 gb of ram instead of 16 gb I bought the exact same ram to make sure everything would work but it didn't. Every time I try to run the DOCP profile on the 4x8gb sticks of RAM it just crashes and turns on the DRAM QLED and then reboots with the default 2133 MHz frequency. Is there a way I can run the RAM at least at like 3600 MHz so its not painfully slow? I think the issue is the motherboard not supporting that high of a bandwidth on the lesser priority spots but I'm not entirely sure. If the only solution is to get another motherboard which can run it at that frequency could y'all link me that please.

More memory sticks = less memory stability.

 

4400MHz is on the edge for Ryzen, so having two extra sticks in there probably puts it over the edge into the unstable territory. You should be able to enter in timings and frequency in manually somewhere in the BIOS, I'm not super familiar with ASUS BIOSes so you're probably best off reading through your motherboard manual to find where to enter them. Someone here who is used to ASUS boards might also be able to help instead. You can probably get the memory to 3600MHz Cl16, maybe even faster.

You can manually set same timings as the DOCP ones, but simply set the speed to 3200/3600/whatever to see if you can get 4 sticks to work.

 

4400 MHz is pretty fast, so unless that kit is on your board's QVL it's a matter of luck (or not as you're finding out).

 

Another note, the ideal 1:1 Infinity Fabric to RAM speed only goes up to 1900 MHz for the 5600x, so above 3600 MHz RAM is where the benefits really drop off.

Got it, yeah I looked at the advanced manual mode and honestly I was beyond confused or overwhelmed by it. Is there any good sources out there that you know which can kind of guide me through how all of that works. When you say timings I remember seeing that in the bios but it means absolutely nothing to me as I don't know how it works.

I've never really looked myself, so you'd have to do some searching for Asus BIOS manually RAM timings.

 

Can you return the RAM kit? Given the FCLK for the 5600x is limited to 1900 MHz RAM faster than 3600 MHz sees practically zero benefit from what I understand. If not, then the above about manually timings will be your best bet.

Yeah I can probably call micro center and see if they're still returnable

That would be ideal. Then you can get a 3600 CL16 kit, set DOCP, and be good to go.

Thanks for your help!

Don't take this the wrong way, but "painfully slow"? In reality (not benchmarking) you will not/should not even notice any difference. All this overclocking and marketing these days. A Ryzen 5 5600 system with 32GB of RAM, whether at 3200 or 4400 should be anything but slow.

 

Just the fact of having more available RAM as opposed to less, but faster RAM would improve overall system performance.

 

IMHO it's splitting hairs. If things are running painfully slow, there's some other issue. To me, painfully slow is 32MB PC133 SDRAM on Pentium classic 133Mhz with 5400 RPM IDE HDD.

 

Not sure about the B550 chipset, I went with an Asus board with the X570 chipset.

 

As to RAM, anything above 3200 is out of the JDEC spec and so RAM rated for higher speeds just means it has been tested to run stable at those speeds. But it depends on that and the motherboard/chipset. Anything running at 3200 and above is technically overclocked RAM.

What you might want to do is go to Asus website and search on your motherboard, click support and then look at the manuals and  documents tab. Download the RAM QVL (Qualified Vendor List) and get some RAM that is on the list. It's just a guide and means Asus has tested those configurations with that board. Doesn't mean that other configurations won't work, but no guarantee they will work either.

Also, there have been several BIOS updates released this year, which may improve stability/compatibility.

 

The latest being version 2423 released on 8/26/2021.
