Question Ram not going over 2133 in appropiate dimm slots

[Bob1nba]

My friend is having an issue with his ram situation. He has a MSI B450 gaming plus motherboard and has 2x8 ddr4 ram @ 3200mhz. His manual says he is supposed to slot his ram in A2 and B2 but when he does he cant get his ram to go over 2133 mhz in his bios. When he puts them in A1 and A2 he gets 3200mhz but his benchmark is bad and he crashes quite frequently now when gaming.

I have the same mobo and I'm able to slot A2 and B2 with no problems and I get 3200mhz speeds in bios. Im not sure if maybe a bio setting is restricting him from getting his ram over 2133 in the appropriate slots or not. Any ideas?

A2 and B2. ALL dual channel motherboards. No exceptions.

Put them in A2 and B2, which are the second and fourth slots over from the CPU going from left to right.

Then, reset the BIOS as follows.


BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.



You will NEED to go into the BIOS and enable the XMP profile for the memory to run at the correct speed. It might even be necessary to manually configure the memory speed and timings, if setting XMP doesn't work.


If that doesn't work, then I would highly recommend that you remove the CPU and check it for bent pins, and make sure that if you are using an aftermarket CPU cooler that it is not OVERLY or UNEVENLY tight, on all sides. A cooler that is tighter in one area than in another can cock the CPU in the socket, and cause a variety of problems.
