Question 3200MHz RAM only working at 2133MHz ?

[hemal_301080]

I currently build a system with i5-12400 and Gigabyte H610 M H V2 DDR4 motherboard.
I am using onboard integrated graphics with new Corsair Vengeance Memory modules, total of 16GB, with 2x8GB modules of RGB RS(Part No CMG8GX4M1E3200C16), both 8GB modules are in separate packet/kit.

Now, system and BIOS shows RAM running at 2133MHz only.
When tried changing XMP profile to Profile1 from Disabled, screen went black and won't boot.

Next time system booted with warning of Previous Bios Settings Being Wrong, then asked to reboot with Load System Default.
Then did it and system started working fine but then RAM is working at 2133MHz again.

How can I use full speed of 3200MHz of this RAM with the above mentioned hardware configuration?

Thanks

Overclock ram manually.

Can you show screenshot from CPU-Z - memory and spd sections?

So your ram modules were not from same kit but purchased separately.
This can introduce compatibility issues.

Yes, they were two separate packets from Corsair, one of each 8GB module. As shown in images, two packets of each 8GB totalling upto 16GB.

I did not try manual overclock though. If two different pieces of 8GB from separate kit is the issue, will a single 16GB kit(cmg16gx4m2e3200c16) consisting of 2x8GB modules solve the issue and work at XMP with 3200MHz?

Yes, it will fix your issue, best is 2x8GB

Ok, so if I got it right, you are suggesting to replace with a single 16GB Kit(CMG16GX4M2E3200C16), consisting of 2x8GB modules and will work fine with XMP from BIOS at 3200MHz afterwards? Rather than current two separate kit of 8GB modules?

Yes!
Additional information: you can mix sets of 2 on dual channel CPU but not mix individual sticks. For example you get 2 sets of 2 sticks, one set of 2 can be on channel 1 (A1 and B1 on Asus) and the 2nd set can be on channel 2 (A2 and B2) but on quad channel cpu (the X99 or any quad channel platform) you cannot mix 2 sets of 2, you neeed a set of 4)

Great, finally glad to know that single 16GB kit with 2 sticks of 8GB inside, will solve my XMP issue and I will get to use full 3200MHz. I have two DIMM slots on my motherboard.

Thanks again

You can try overclocking it manually. May not get to 3200mhz.
But 2933mhz or 3000mhz might be possible.
Set DDR voltage: 1.35V
Command Rate: 2T
Latencies: 16-20-20-38

Set frequency to 2133mhz, test.
Then increase frequency gradually and test after each step - 2400,2600,2800,2933,3000,3200mhz.
When test fails, then return to previous settings that worked.

Ok, and when it does not work with manual overclocking after these changes, BIOS will warn me and let me LOAD DEFAULTS so that I can go ahead and try another setting.

It may be necessary to reset BIOS settings with onboard CLEAR_CMOS jumper.

Ok, will do this and let you know the outcome
