B650 rog strix e e gaming 4x32gb ram

[Blackcity]

Hi guys, I'm a beginner, I hope to find someone who can help me, I have a rog strix b650 ee gaming 7800x3d 4x32gb ram dominator cl 30 but with the Expo profile I can't make them read at 6000mhz but only 4800mhz in dual channel, it didn't happen, what parameters do you recommend, thank you very much for your help

Hello Blackcity

Are you combining two memory kits?

If so, this is why you're having issues.

[Blackcity]

with two sticks the expo profile works for me and 6000mhz with 4 sticks the expo profile doesn't work you only set it to auto and the rams are read at 4800mhz

You didn't answer my question.

When you combine two memory kits, you're doubling up on the capacity with the same frequency. So, what you're doing is running the memory out of specification, it would be best to stick with one memory kit (2x32GB) in the A2-B2 slots.

[Blackcity]

doing this way works 2x32gb the problem is the 4 modules that do not go above 4800mhz

[Nate152]

This is to be expected when combining two memory kits.

[Blackcity]

could you help me with a manual OC the 4 modules are all the same

[Nate152]

I'm not familiar with AMD motherboards so I don't know what voltages would help to overclock your memory.

If you're just gaming, 64GB (2x32GB) is plenty and games prefer speed over capacity.

If using your pc as a work pc, 128GB can benefit, but you'll have to settle for a lower frequency. High speed memory isn't as important for a work pc.

now i managed to get 5600 mhz by setting everything manually but the system is not stable at all

To confirm, you have two of these memory kits?

DOMINATOR® PLATINUM RGB 64GB (2x32GB) DDR5 DRAM 6000MT/s CL30 AMD EXPO Memory Kit — Grey

The timings on that memory kit are pretty tight at cl 30, you could try loosening the timings some, this will ease up on the cpu's memory controller.

In the bios, on the Ai Tweaker page, scroll down to Dram Timing Control and click on that.

At the top of the page are the 4 primary timings and the command rate.

If you enabled EXPO, set the Dram Frequency to 5600MHz.

The primary timings should be set like so:

30

36

36

76

Command Rate 2N

Try changing them to:

36

40

40

90

Command Rate 2N

Hit F10 and Enter to save and exit.

It may or may not boot with the looser timings, cross your fingers and give it a try.

How does it go?
