Viper Blackout DDR4 16GB 4133MHz Memory Kit Review

Overclocking

Not that many people realize they overclock their memory. That quick trip into your BIOS on a new build to enable X.M.P. profile your particular memory kit advertises is actually overclocking, albeit done previously by the manufacturer with those settings saved to the modules themselves. We’ll try our hand at going beyond what Viper has provided with this Blackout kit.

Viper’s Blackout memory kit is based on Samsung’s legendary B-Die memory, so we expect good things here. We start with a small bump to an even 4200MHz effective and it doesn’t bat an eye.

4300MHz is also painless with no change in settings needed.

This shaves about 2 seconds off of our stock (XMP) Super-Pi run of 6:56.387.

4400MHz required a small boost in memory voltage from the XMP 1.40V to 1.42V to get stable, but we didn’t need to change timings.

This shaved a tiny bit more off our Super Pi time. We were unable to get 4500MHz to take, even at 1.45V (the highest we test) even with relaxed timings.
