DDR4 not getting 3600

[lavosoj]

Corsair Vengeance LPX 2X8 3600MHz
Asus TUF Faming X570-Pro
AMD Ryzen 5 3400G 4 Core 8 Threads APU
Asus GeForce RTX 3060 Strix Gaming OC V2

Ram does not hit 3600, keep getting 2100 and under.
Just realized, tested some things, got my ram to 3200 Motherboard supports 4000 and CPU 2933, what would be the best spot to overclock the ram.

Google your chip, amd says max speed is 2933 with single ranks sticks.

Take a screenshot of the memory tab not SPD. Also its easy to mix up 3600 MT/s and 1600 MHz. Both are the same thing. DDR is double-data rate. 2 transfer per cycle. This is why 1600 Mhz is DDR4-3600.

I did but I dont even hit 2900, just realized I could have tried to OC to something below 3600, when I tried 3600 kept booting into safe mode.

It looks like your XMP profile isn't enabled or using profile #2. Running at DDR4-3200 CL18

I got D.O.C.P enabled, Fequenzy set 3200 instead of auto, when set to 3600 computer starts to safe mode. If I try 3266 and up computer starts in safe mode.

You are limited by the cpu.

3400G: This APU supports up to 64 GiB of dual-channel DDR4-2933 memory

IIRC, the 3400g is based on Zen+, which doesn't like going much above 3200-3466MT/s with the RAM. 3600MT/s may be possible if you have the right RAM and you set the voltages and subtimings manually.
The memory controller in Zen+ CPU's isn't as good as Zen 2 and Zen 3 chips which usually hits 3600MT/s fairly easily.

You can always try the Ryzen DRAM calculator by 1usmus, which will give you a list of speeds, timings and voltages you can enter manually. You'll have to use another program called Thaiphoon burner to see which company manufacturers the chips on your RAM. For example, your Corsair vengeance sticks may be using Hynix-M dies.

DR 1600 = 3200 not 3600

What bios are you on? Tried newest? 3400G should be able to handle above 3400, but maybe no 3600. Are you using the A2-B2-slots? If you are using A1-B1 that can be the explanation.

From what I can find

the 3400G officially only supports 2933MHz Single Rank and 2667MHz Dual Rank

Also reading the QVL list it only shows max 3200MHz when using 2nd Gen Ryzen with IGP

Anything beyond that is not guaranteed and considered overclocking

3200 is actually pretty decent for this CPU

 

[eidairaman1]

3200 is best you will get unless if @cadaveca has a thought on this...

ew, some old ryzen, and this is explanation... get 5600X and enjoy ram speeds and stability.
