Overclocking computer components
has gone from exclusively the domain of enthusiasts
to something anyone can do with a couple of mouse clicks.
And this has been especially true for RAM,
thanks to Intel's Extreme Memory Profiles,
better known as XMP.
But XMP hasn't seen a significant update since 2007.
So the powers that be decided it was time
to finally give us one with the new XMP 3.0
due out with the release of DDR5 memory.
To understand why XMP 3.0 is a big deal,
it'll help to give you a quick primer
on what XMP is to begin with.
So you know how when you buy RAM,
it has a speed and a set of timings listed on it?
Well, if you've ever plugged a new stick of memory
into your motherboard,
you might've seen that it defaults to a much lower speed.
This is because each generation of DDR RAM
has a default speed that's set by an industry body
called JEDEC, or JEDEC, or JEDEC, JEDEC.
I'm on three hours of sleep, Andy.
To ensure stability and compatibility.
This is the speed your RAM will run at
unless you change your settings.
XMP was devised partially as a way to allow users
to quickly set their RAM to the advertised speed instead.
RAM that supports XMP has a very small amount
of internal storage that contains XMP profiles
from the factory with one of them
matching the advertised speeds and timings.
To set it, you simply need to find the XMP setting
in your BIOS, often on the front page,
and the system will automatically apply
those settings for you.
Although it's overclocking in the sense that XMP
makes the RAM run faster than the base JEDEC specification,
you shouldn't have stability issues
since the modules themselves are designed
to run at the speed printed on the label.
Although XMP is an Intel technology,
it's also been implemented on AMD motherboards
as AMP, DOCP, or EOCP.
So if you have a CPU from Team Red,
look for one of these settings in your BIOS instead,
and you should see an option to enable the correct speeds.
But how exactly does XMP 3.0 improve upon this?
We'll tell you right after we thank Secret Lab
for sponsoring this video.
Secret Lab chairs are engineered
to keep you incredibly comfortable
for long hours at work and play.
Their new Titan Evo 2022 chair has four-way lumbar support,
ultra comfortable lines of different seat materials,
and more.
All chairs come with up to a five-year extended warranty
and a 49-day return policy.

So XMP 3.0,
is supported by Intel's 12th Gen Alder Lake CPUs,
which also support the aforementioned DDR5.
XMP 3.0 will improve on the existing XMP scheme
in a few ways.
First, it'll raise the number of profiles
you'll get from the factory from two to three,
so it'll be easier to tweak your modules
to determine which profile gives you the best blend
of stability and performance for any given application.
Mm, blend it up.
Give me some froth.
Not only that,
but the additional onboard storage dedicated to XMP
will allow for two more XMP profiles
that you can customize.
So if you're more of an enthusiast overclocker
who wants to do additional tweaking
to get the most performance possible out of your RAM kit,
XMP 3.0 will make it easier to save profiles
you've tested on your own,
and you'll even be able to rename them to avoid confusion.
Wow, technology.
But aside from making the overclocking experience
more convenient,
XMP 3.0's new features could also result
in real performance benefits.
Alder Lake CPUs have something called Dynamic Memory, which,
as you can see here, is the best way to get the most performance
out of your RAM kit.
Where the system can detect
if the application you're currently using
could benefit from boosted RAM speeds
and adjust them accordingly.
And if you're running an AMD CPU,
vendors could offer XMP profiles
tuned more specifically for Ryzen,
as these CPUs are notorious
for being more sensitive to RAM speeds
than their counterparts from Intel.
Of course, XMP 3.0 is only going to be available
for Intel platforms to start,
but we'd expect it to appear on AMD platforms
once Zen 4 is released sometime in 2022.
Don't go too crazy tweaking your overclock,
as there's nothing extreme about frying your motherboard.
Guys, thanks for watching this video.
That was very extreme of you.
