Is your 3000 MHz Ram Showing As 2133? It could be that your motherboard can only handle 3200 MHz RAM, which causes it to reduce the clock speed to that level.

Why 3000 MHz Ram Showing As 2133

Why 3000 MHz Ram Showing As 2133?

Because you didn’t enable XMP or your motherboard and CPU don’t support higher frequencies than 2133MHz. JEDEC (Joint Electron Device Engineering Council) and XMP are the two RAM speed standards (eXtreme Memory Profile).

The vast majority of 3200MHz RAM kits have a default JEDEC speed of 2133MHz, and the motherboard’s BIOS must be configured to support the 3200MHz speed.

This is because many CPUs and motherboards, especially older and lower-end versions, are unable to support memory at the faster rates and lower latencies that XMP permits, hence by default, they will operate at the slower JEDEC speed to ensure compatibility (so that your PC will still be able to turn on if you use XMP RAM at speeds that your CPU and motherboard do not support).

There are JEDEC 3200MHz memory kits, but they are uncommon, have significant latency, and are therefore slower than XMP 3200MHz memory kits.

Even if a motherboard and CPU are XMP compliant, not all of them will be able to operate at 3200MHz. If the quickest option fails to boot, the user can choose a slower alternative (but still quicker than JEDEC) by using some XMP RAM kits’ numerous XMP profiles for various memory frequencies.

Any motherboard with a Ryzen CPU should support XMP up to 3200MHz; if it’s a first or second-generation Ryzen CPU, the integrated memory controller might not be up to the task of operating at this speed. If 3200MHz doesn’t work, try using a slower profile or manually setting the speed to 3000MHz.

Fully supporting XMP, Intel Z-series motherboards should be able to operate RAM at 3200 MHz with any CPU (though some low-end Skylake CPUs may not be fully stable).

Depending on which CPU is paired with them, low-end Intel motherboards are limited to 2133MHz, 2400MHz, 2666MHz, or 2933MHz. While some of these boards might support XMP, not all of them do, and regardless of whether XMP is enabled, the maximum memory bus frequency will be constrained.

Restart your computer, then press the BIOS key (you can find this information on the motherboard manufacturer’s website) to enable XMP. It’s typically “Delete” or a function key that opens the BIOS.

Next, search the memory settings and, if there is an option for “XMP” or “DOCP,” choose the 3200MHz XMP profile. Be aware that turning on XMP can void the CPU’s warranty.

How To Fix 3000MHz Ram Showing As 2133?

There can be a few reasons for this. First, the motherboard you’re using could not be able to run at speeds beyond 2133MHz. Therefore the RAM is sluggishly catching up. Second, the speed that is actually being used may not have been accurately reported.

Some boards that were manufactured had a BIOS firmware fault that reported the RAM’s actual speed incorrectly. I don’t remember what manufacturer of motherboards this issue affected (though I believe it affected Gigabyte boards). Still, from what I remember reading not long ago, that flaw has since been fixed by a BIOS update.

The other less likely possibility is that the RAM (at least one stick if you bought many sticks) is flawed or incorrectly labeled and is not running any faster than 2133. The only way to be sure in this situation is to move the RAM to another computer and verify whether it indicates a faster speed there (assuming, of course, that it is a different motherboard brand and model to resolve the problems I outlined above.).

3200MHz Ram Running At 2133 Ryzen

The standard speed for ddr4 is 2133. Your system appears to be running at default settings and is not configured. Because your RAM is OC RAM and not JDEC compliant, it will not operate at its rated SPD, and XMP profiles won’t function.

Why Is My RAM Showing A Lower Speed?

You May Have Incompatible RAM Modules. Your RAM will only be able to operate at the frequency of the slower stick if you have two RAM sticks in the same PC that operate at different frequencies (for example, 3200 MHz and 2133 MHz).

Can I Use 2133 And 3000 RAM Together?

Sure, you can. Said, the motherboard will reduce the speed so it can function. Even if you can install RAM running at 3000 MHz, it will only be clocked down to 2133 MHz.


A ddr4 3000 MHz Ram Showing As 2133. Check your bios in the memory section to see whether the “Xmp” auto overclock profile is enabled for the higher frequency stated. There ought to be one with each set needed to activate XMP.

Now, the CPU and motherboard must be capable for XMP to function. I’m unsure if you’re using an AMD or an Intel processor. I can give you further advice on the settings you might require if you can be a little more detailed about the software you are using.

Frequently Asked Questions

Why is my RAM running at 2133 MHz rather than 2400?

DDR4 2400 is the verified RAM speed for your system. DDR4 3200 is set to 2133 by default unless XMP is enabled in the BIOS. You will continue to run at 2133 if XMP is not listed in the settings and a new BIOS does not add that extra parameter.

What causes my 3000 MHz RAM to operate at 2666 MHz?

In your UEFI BIOS, you must overclock it to the recommended frequency. Enabling XMP will enable this. Since you’re using an Asus motherboard, you should find this in the advanced mode under a tab called “AI Tweaker” or “Extreme Tweaker.”

Why is the RAM running at half speed?

Your RAM will still function if the right XMP profile isn’t enabled in your BIOS, but it will be downclocked to one of the preset timings. Without XMP, you’re throwing away all that extra performance.

Can I combine 2133 and 3000 RAM?

No. Because the chips are only made to operate at 2133 or 2400 MHz, a system with faster RAM and a faster memory controller may have instability.
