The RAM world is a great bazaar where we can set the highest number of parameters and where we could spend months exploring stability with each of them. To simplify this complex puzzle, manufacturers in partnership with AMD and Intel provide profiles that by converting the two settings will give us everything it needs to increase its performance in the manufacturer-specified parameters.
These profiles are called XMP and even though they work in UEFI, many times motherboards fail and don't know them as they should, so how do you know if they work normally?
Two very simple programs will tell us if everything is fine
These systems are CPU-Z and AIDA64 Extreme, which is good to know if everything is going in the right direction and we've already talked about it in some of their publications that you can see in previous links.
To know in advance the features of our memories in terms of speed and inclination, we will only need to turn on AIDA64 and go to its menu on the left. In it we will open the "Resources" tab and then "Summary".
Once inside, on the right side of the program will appear a list of features where we will need to look only for RAM memory. This will be marked as a general rule DIMM1, DIMM2, DIMM3 etc.
In them we will have a code name for our memories or a specific model and in some cases both can be read. On the right we will see a series of numbers separated by dashes and behind them the MHz value symbol.
The first is latitude, the second is the actual memory speed at MHz at those frequencies. Each memory has a series of profiles that can be used, but one is the best (sometimes there are two main at the same time).
XMP profile on RAM: according to JEDEC and according to manufacturer
This profile and adjustment is what your commercially viable memory type, in our case 16-18-18-36 @ 1600 MHz (3200 MHz active is the retail value used). Usually, the final profile provided by AIDA64 is the correct one, at which point it is the most common.
But to make sure this is true and everything is fine, we will go to the CPU-Z, where it is turned on so you will need to go to the SPD tab.
In it we will also see the key profiles ordered by JEDEC and the main profile, which will be the lowest latitude and highest speed it provides. In addition, we can look at each module for a specific memory by looking at its Slots.
After confirming that, in fact, the profile is the same as the AIDA64, we will go to the memory tab, where we will see in real-time the RAM, divider frequency and the 6 main lattes that define performance versus start time.
If these numbers match the specifications of our memory, it is because the profile is used and works well, then we will have RAM running at its maximum serial speed.
