[SOLVED] Max ram speeds for using all slots?

[talhaskrillx]

I am using Ryzen 7 2700 and Asus B450M-A motherboard.
What will be the max memory frequency I can get If I use all the slots?

what the motherboard spec said?

from your other thread. are you mixing ram kit/speed?

Thanks for the reply.
My motherboard is Asus B450M-A it is rated as 3200Mhz on XMP profile.
My processor can also support 3200Mhz memory frequency it is Ryzen 7 2700 @3.2GHZ
It was working fine with 2 sticks. Unfortunately, I bought another Kit 8x2 but with different timings of the same brand.
Now with 4 sticks max it can do is 2866Mhz.
G.skill Ripjaws V DDR4-3600MHz CL19-20-20-40 1.35V(the Kit I had before that was working fine with XMP @3200Mhz) Red in color

G.skill Ripjaws V DDR4-3600MHz CL18-22-22-42 1.35V ( Kit I bought that's not working with XPM @3200Mhz) Black in color

mixing kit, different timing. try oc by hand. use the slower timing and might up the voltage too

The color is irrelevant.

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.
Ram must be matched for proper operation.

You are fortunate that it runs at all.
The lower speed is what the motherboard bios was able to find that let the ram work.

You can sometimes compensate for errors by increasing the ram voltage in the motherboard bios.

If you needed the extra ram, you did ok.
If, somehow you expected better performance, just remove the new addition.

Thanks for all the help and explanation. I should have done my research before buying the different kit.
