ROG STRIX X670E-A 128GB Max Ram Speed

Level 7

I'm trying to get the best RAM speed on my system, As of now im getting 

128 GB - Speed : 3600 MHz

I have T-Force Delta RGB DDR5 32GB x 4 

I know that these are not on the QVL list and im not looking to speed up to 6000 MHz, I just want to know if any one else has this and have managed to go above 3600 MHz.. or if anyone here can guide me how to tweak so that I can test various values to get this kit to the best Speed.

The default DOCP Profile Fails.


Processor : AMD Ryzen 9 7950X3D
RAM : 128 GB (T-Force Delta RGB DDR5 32GB x 4)
Motherboard : X670E-A
Bios Version : 1415

Can you please specify the memory kit part number? 6000MT with 128Gb is not possible on this platform. If you are combining memory kits you will be on your own tuning them as this is not supported by the manufacturers as the kits perimeters within the DOCP profile are no longer valid.

Hi, the part number for the kits are FF4D532G6000HC38ABK

I have 2 of the same kits "32GB DDR5 6000 CL38"

I know 6000MT with 128GB is not possible, i just want to make sure I get the best top speed , currently being at 3600 Mhz feels like its just a waste of money for me buying these kits.

The trouble you have when doing things this way is that everything the memory vendor has tried to account for when binning is no longer valid. I.e. frequency, timings, voltages - so there is very little one can do to help you vicariously. You will need to tune them manually. Alternatively, return both and purchase a single kit in 128GB density.

Thanks! Do you know a Single Kit of 128 GB that would get me a good speed that is compatible with this Motherboard and Processor! Thank You.

Hello, inspect the motherboard's memory QVL:

I would recommend opting for 2 DIMM kits. Be sure to inspect the socket support column on the far right as this will indicate how many modules were validated.
