DDR4 Recommendations for Asus/Ryzen combo

[Andybtsn]

Hi all,

Current spec:

ASUS PRIME B550M-A
AMD RYZEN 5 3600 6 CORE 4.2GHZ
ADATA GAMMIX 16GB (2X8GB) 3600MHZ

I bought an extra 2 x 8 GB sticks to expand my RAM to 32 GB. However, my PC became unstable, a lot of restarts that only occurred after the new RAM was installed. I returned it after the supplier told me "I see you are using a Ryzen CPU. Unfortunately, these are finicky when trying to run 4 DIMMS of RAM, usually involving loosening the timings or the speed down from 3600 to 3200mhz or sometimes even 3000mhz. If you require upgrading to 32GB of RAM, I'd highly suggest replacing the RAM you currently have with 2x16GB sticks."

Is this accurate info?

Do I go with their recommendations and just replace the RAM with 2 x 16gb sticks? Seems a waste of the extra slots.

Thanks,

Andy

That advice is indeed correct.
Any set of 3200 c16 ram (2x 16gb) should do the trick.
As always update the bios to the latest version to ensure maximum ram compatibility

Personally would just get them from the MM as ram kits very rarely fail...so saving you some £££

Strange.
When I had a 3600 with a B450 MSI, I ran 4x8GB Corsair 3600mhz and ran fine.

Edit: sorry I just saw you have an Asus

I’ve had no problems running 4x8gb on my B450, even have them overclocked to 3800mhz. The XMP was 3200mhz but used the ryzen DRAM calc for a starting point at higher speeds then further tightened some of the sub timings.

If you just want some easy plug n play then 2x16gb is the way to go.

Yes they are correct, it's a royal pain getting 4 sticks to work on Ryzen at xmp DDR4 3600mhz even on 5000 series cpus and X570 boards, you have to find memory kits that are on the recommended motherboards RAM guide and in some cases even the same version firmware on the RAM or they cause issues. Welcome to AMD if you want to run XMP or EXPO as they call their version, even on the new 7000 series cpus the same issue with DDR5 too .. unless you run at JEDEC speeds or get lucky with motherboard and cpu with a good memory controller.


Get 2 x 16GB sticks and sell the previous ones on it will save a lot of headaches and make sure they are also Ryzen compatible not Intel specced only.


I would try these the Ryzen Tuned versions, I use the 2 x 32GB version and were only ones that worked out of the box without messing about on my system by setting XMP on.

if you update your bios to support 5000 series cpu's and got a 5800/5900x you can run 4 dimms and to great affect, when i had my 5950x build i used some team group ripped ddr4 from ocuk its 3600mhz cl14 and i managed to get all 4 working together and saw around 10% better performance vs 2 sticks in games and benchmarks.

asus arn't bad, just need to check bios updates everynow and then, if the system is stable thers no need to update, my old setup had the asus crosshair extreme x570 with the above

I did update the BIOS, but I never altered the speeds though so maybe this could have resolved matters

ryzen 3000 was always a bit iffy when i came to ram sppeds and configurations (2-4 sticks), back then i had the 3950x from a i9 7900x, first few months on the new x570 platform were very dark, ram speed at best was 2933mhz, but as agesa versions dropped it did get a lot better, but it was 6+ months until 3600mhz was possible even then it was touch and go for other owners.

ryzen 5000 is where everything changed, support for 3600mhz out of box, most cpu's in that geneartion had strong IMC's, which allowed for endless tuning of ddr4 modules that were samsung b die, you could get some pretty crazy timings too.

but going back to your original post, if you need more ram opt for a 2x16gb kit, to play it safe look around the 3200mhz mark, that way you shouldn't run into any no boot or instability problems.

have a look at this kit, 3200mhz speed and cl16 timings, not bad tbh
