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.
