Patriot Memory Unveils Viper 4 Blackout in DDR4-4133, DDR4-4266, and DDR4-4400

Patriot Memory today unveiled new high-frequency variants of its Viper 4 Blackout memory modules which debuted in May 2020. At the time, the Viper 4 Blackout series came in frequency based variants of up to DDR4-3600. Today, Patriot is introducing new DDR4-4133, DDR4-4266, and DDR4-4400 variants, all of which are in 16 GB (2x 8 GB) dual-channel kits. These modules use binned memory chips, and a 10-layer PCB for better signalling. Patriot has tested the hits to offer their advertised frequencies on both Intel Core and 3rd Gen AMD Ryzen platforms.

The DDR4-4133 variant (PVB416G413C8K) achieves its advertised speeds at 18-22-22-42 timings, and 1.4 V. The DDR4-4266 variant (PVB416G426C8K) ticks at 18-26-26-46 timings, and 1.45 V. The top-spec DDR4-4400 variant (PVB416G440C8K) was tested with the same 18-26-26-46 timings as the DDR4-4266 variant, but with 1.5 V module voltage. All three variants are backed by limited lifetime warranty. The company didn't reveal pricing.

Asthetically pleasing IMHO, but they appear to be a bit taller than usual, which may cause clearance issues with some tower coolers.

However, alot of the recently announced coolers are being made specifically with higher clearance on the pipes & fins to avoid this, so there may be hope after all :)

This is an old heatsink that they've re-introduced. I prefer the Viper Steel look.

Personally, I'd rather have a 3600Mhz or even 3800mhz 14-14-14-34 kit than 4000+mhz with sloppy timings

I liked the Viper of the X38 (DDR2) days more personally.

G.Skill has 3800 CL14 and 4400 CL17 options: www.techpowerup.com/268402/g-skill-releases-ddr4-4400-cl17-memory-kits-with-high-capacity-16gb-modules

But as with all high end G.Skill modules availability is scarce. I've been keeping an eye on the 3800 CL14 and this comes and goes when it comes to availablity. Never staying in stock for long.
That being said Micron has some pretty nice E-Die based options coming.

I didn't realize any DDR4 modules could be operated safely at 1.5v

There have been plenty of 1.5v DDR4 modules before. Thats literally no problem considering how little heat these put out.

JEDEC specs say up to 1.35V. You can, of course, go outside JEDEC, but then you don't have guaranteed compatibility.

They can, and AMD platform does'nt suffer from the fried intel memory controller bug if you go beyond 1.35v.
