Review: NZXT N7 B650E

CPU overclocking:

Well, I have to admit that I had in mind that the multiplier of the non-X Ryzen was blocked but of course this is not the case at all. So let’s see what we can expect from our Ryzen 5 7600 and why not go for the score of its big brother, the Ryzen 5 7600X.

To overclock our processor, we must either do it directly via the BIOS or via the AMD Ryzen Master software. It is the latter solution that we chose for these first tests.

Protocol:

Before starting, it is necessary to have one or more reference scores with your processors at stock frequencies, i.e., without having made any modification except having activated the XMP/EXPO profile. It is also very important to have a sheet of paper at hand that will allow you to note down all the tests that you will perform as well as the results or failures. Personally, I have hundreds of sheets of my tests on which I sometimes return to know how the processor behaved on such motherboard or in such test conditions. My own little bible.

For H24 overclocking, it will of course be necessary to take more time to fine-tune the voltage in order to provide it with the minimum necessary but also to adjust each core independently if you want to take advantage of the maximum performance.

Load-Line Calibration:

The idea of modifying the Load Line Calibration is that the voltage chosen should be as close as possible to the voltage in load. NZXT only offers three levels of “calibration”. We opted for Level 1 in order to have as little vdroop as possible. Basically, I want the voltage chosen to be as close as possible to the load voltage. The readings are taken with a multimeter on the PCB of the motherboard. It is very important to know the real voltage brought to the different components but especially to your processor.

Ryzen 5 7600 Operation:

Once again, it is via the OS that we will begin our overclocking tests using AMD Ryzen Master. It’s a tool that can be used very easily and is therefore very intuitive provided that you have a good understanding of the structure of your processor and here of our Ryzen 5 7600. It’s quite easy since the 6 cores are integrated in a single CCD. Overclocking is a bit more subtle when the processor has two CCDs as we explained with the Ryzen 9 7950X.

We pushed the 6 cores to 5500 MHz and raised the voltage to 1.26 volts. The idea being to exceed the base score of a Ryzen 5 7600X which gets a score under Cinebench R23 of 15662 in multi. We also put you the capture of the stock score and of course at 5500 MHz with our best memory profile obtained on the previous page.

Good news as our score improves significantly and as we expected, we manage to exceed the stock performance of the Ryzen 7600X under Cinebench R23. Finally, nothing to reproach to this motherboard regarding overclocking and as we said, given the power supply stage you should not encounter any problem with the Ryzen 9 7950X.
