ram HyperX Predator 4x8GB cannot run at 3200MHz

[Agonys]

Hi, I've built new PC recently and everything was fine, had 2 sticks of HyperX predator RGB 8GB (2x8) and it was running at 3200MHz normally. Then I decided to buy 2 more and when installed weird things starts to happen. Currently I've dual boot for windows 10 and ubuntu 20.04, when running first profile on XMP (or D.O.C.P on AMD) that sets my ram to 3200MHz 16-18-18 sometimes ubuntu just freezes and then I need to manually restart it, also windows somethimes doesn't even boot. Everything works fine at 3000MHz 16-17-17. I've even ran memtest86 and everything was fine for every single ram and for all them together, just setting them to 3200MHz make problems.

 

Probably good to notice that I've bought 2x8GB from one shop and then week later bought 2x8GB from other one. I've checked DRAM manufacturers and 2 of them are from Kingston and second half of them are from SK Hynix. Everything except DRAM manufacturers (and serial numbers of course) is the same. Could the manufacturers difference be the problem with setting them all to given frequency? 

 

My build:

CPU: AMD Ryzen 5 3600

CPU Cooler: be quiet! Pure Rock 2 Czarny 120mm

Motherboard: Asus TUF B450-PLUS GAMING ATX AM4

Memory: 4x8GB HyperX Predator RGB DDR4-3200 CL16
Storage: ADATA XPG SX8200 Pro 512GB M.2
Graphic card: Gigabyte GeForce RTX 3060 12GB

PSU: SilentiumPC Supremo M2 550W 80 Plus Gold

Case: SilentiumPC Regnum RG6V EVO TG ARGB

Reseat CPU yet?  Just to ensure all contacts are good

I've disassembled and assembled whole PC after getting this weird issue but still no changes.

This might be the problem you are having with the RAM. The memory controller may not like having mixed chips (the actual memory modules on each RAM module).

That and that the ryzen 3000 cpus sometimes have problems with 4 sticks at high speeds.

So would it be better to return all ram to sellers and order 2x16GB?

That could fix the problem, I have had that issue before. Getting the same RAM 6 months later usually means the chips are from an other source.

Have you tried each stick individually to verify each stick will operate at 3200Mhz. If all 4 will operate at 3200 on their own then it's the mixing that has to be the issue.

If you find that one stick will not operate at spec then that one needs to go back to the manufacturer for replacement.

Yes, I would recommend returning your RAM to the sellers and buy a 2x16GB kit instead of using 4x8GB (2 kits of 2 8GB modules) to prevent any issues and get the best performance possible with your system.

I had a feeling that was also the case here too, just like 1st and 2nd gen Ryzen. 

[Agonys]

Okay, so I'll return all of them and then order new set of 2x16GB. Thanks everyone for response

My B450M board refuses to run sticks 1 and 3 over 3066MHz and only slot 2 & 4 can do up to 3600MHz+
