How to Fix Windows computer won’t boot after enabling XMP in BIOS

Prepare to learn How to Fix Windows computer won't boot after enabling XMP in BIOS, because here is all you need.

You can switch between a number of memory profiles that XMP holds within itself. You can change the frequency, voltage, and timing of your memory, which is, in a way, the coolest part. That being said, we have seen systems on Windows refuse to boot after the profile application of XMP. In this article, we will go through this issue and how you can troubleshoot it.

Why is my computer not booting after XMP profile?

This might be because your motherboard doesn't support XMP. An inappropriate setting of voltage can also create this issue. 

Fix Windows PC won't turn on after enabling XMP

Here's what you can do if your Windows PC fails to boot after enabling XMP from the BIOS. 

See if your motherboard supports XMP or not. 

Try CMOS reset once more.

You can overclock your RAM manually. 

Direct Voltage Settings 

You should replace your RAM. 

Now, let me explain them in detail.

1] Check if XMP is supported on your motherboard.

When dealing with XMP, this is all about your RAM and not about the motherboard. Whereas, XMP is never going to work unless your motherboard supports 3200 MTS. The 3200 MTS data rate signifies 1600MHz because, in DDR RAM, the data rate is twice the frequency or clock speed.

Secondly, reset the CMOS again.

Removal and reinstallation of the CMOS battery is one of the most reliable means of BIOS reset. The timing you have set in the XMP settings may not be compatible with your motherboard. You can then look into whether changing the XMP timing resolves this issue. You will have to follow the process below for CMOS clearance.

Disconnect the peripherals from your computer system.

Then, power cables.

Find the battery on the motherboard once you have opened up the CPU cover.

The battery may be either connected by a cable to a header, or it may be in a holder, horizontal or vertical. If the battery is in a case, pay attention to the plus and minus signs on it. For careful removal, take a medium flat-blade screwdriver to release the connector of the battery. Remove the wire that connects the battery to the header, if any.

Re-screw the battery, boot up your computer and reconnect all the cables but after an hour has gone.

Finally, check if the problem has disappeared.

3] The RAM speed is too higher of what's set, and that has to be fixed manually.

The XMP profile may be forcing the processor to run more clock speed than the defined one, in which you haven't changed yet. Some devices, by default, are set at a maximum memory speed of 3200 MHz. A typical example of this will be the Ryzen 5 3600x. If your RAM is faster than 3200 MHz, then the XMP profile may try to overclock your machine. If the system fails to boot three times in succession because of issues with memory, BIOS will then prompt you for an option to return to defaults. You can do a CMOS reset to boot into the system to get into the BIOS. Inside the BIOS, look for XMP Profile and change the RAM speed to 3200 MHz-which is the default maximum. If it does work, you will be able to have the RAM run at full speed without boosting the CPU simply by fiddling with the settings for the RAM. 4] Manually adjust the voltage

We will try to enable XMP by manually setting the voltage if all else fails. Firstly, we start BIOS and then change it accordingly .

Pulse Voltage - 1.40 volts 

Dam VDDQ voltage: 1.40 volts 

voltage of the CPU system agent—1.28 volts 

Advanced Memory Voltages for the IVR Transmitter: 1.40 volts 

Memory controller with an advanced memory voltage of 1.38 volts

Also, ensure that the problem persists.

Step 5: Replace the RAM.

If all else fails, then the problem could be your RAM.

If you have two sticks of memory in your computer, try turning it on with only one in. If it wont start up, then turn it off and try removing the other and putting it back in. If that doesn't work, try swapping the RAM in your machine with another one or borrowing some from a friend. Replace the faulty RAM module or service your motherboard if you come to the conclusion that either one or both of your RAM modules have failed. 

That's all about How to Fix Windows computer won't boot after enabling XMP in BIOS, so we hope we were as useful as possible for you.
