Patriot Viper 4 Blackout DDR4, Featuring Samsung B Die

Choose Your Own Frequency, DDR4-4000 Or DDR4-3833

This Patriot Viper 4 Blackout DDR4 kit is aiming for maximum compatibility by using Samsung B die silicon as well as offering two different XMP 2.0 profiles in case your motherboard isn’t feeling up to handling DDR4-4000.  As the name implies the Viper 4 Blackout kit does not feature stickers, nor RGBs nor colourful heatspreaders, they are a nice understated black.  The timings for DR4-4000 are 19-19-19-39, as tested by Overclocker’s Club.

OCC tested both these DIMMs with both a Ryzen 3800X and Ryzen 5800X on an ASUS X570 ROG Crosshair VIII HERO Wi-Fi combo, as well as a Core i9-10900K paired with the MSI Z490 Unify for overclocking.  The Vermeer platform hit DDR4-4000, 16-16-16-35-50 @ 1T, while the 3800X topped out at DDR4-3800, running 14-15-15-35-50 @ 1T.

On the Intel platform did things a little differently, DDR4-4000 15-16-16-36-50 @ 2T was the most effective overclock they reached.  In all cases, overclocking took a bit of work so this kit might not be the best choice for someone with limited time and experience in overclocking.  The XMP 2.0 profiles worked beautifully, so the kit is recommended for those who just want to drop in some RAM and start computing.

The full review can be found here.


This memory kit from Patriot comes with a 4000 MT/s rated XMP profile as well as a secondary 3833 MT/s just in case your CPU doesn't want to comply. Cut from the infamous Samsung B-die memory, which is well known for its high compatibility across multiple generations of CPUs and chipsets. This Viper 4 Blackout kit is also already in a good starting position for those who are looking to squeeze something extra when it comes to overclocking.

    Never again, own 2*2*8GB of 3200 and the 2 sets are total different.

    One is 2133 base and awesome
    Other is 2667 base and not stable even on 3200…
