Patriot Viper Elite II 16GB DDR4-3600 CL20
The 3600 MT/s speed and XMP 2.0 support make this single 16GB module a straightforward upgrade for DDR4 systems needing a quick performance lift. Its aluminum heat spreader with a distinct Viper design adds reliable thermal management without bulk, backed by a limited lifetime warranty. This module is best for budget-conscious gamers building or upgrading a desktop who prioritize easy, automatic overclocking over ultra-low latency.

Snapshot
The 30-Second Version
One stick of 16GB DDR4 at 3600 CL20. Fine for filling a slot, bad for chasing frames. Buy a dual-channel kit unless this is dirt cheap.
Pros & Cons
Pros
- Low-profile heat spreader fits tight builds 79th
- XMP 2.0 makes setup painless 76th
- Decent latency for the speed class
- Works on both Intel and AMD DDR4 platforms
Cons
- Single stick kills dual-channel performance
- CL20 is loose for 3600 MT/s
- No RGB, if that's your thing
- Pricing is all over the place
What owners think
The Word on the Street
The proof
Performance
The 3600 MT/s speed lands in the middle of the pack in our database, but the CL20 latency is what really defines this kit. That's well above average for latency, which helps offset the single-channel penalty a bit, but it's still not going to wow anyone. For gaming, it scores 62.9 out of 100, which is fine for casual play but nothing to brag about. Workstation tasks are even less impressive at 54.3. The heat spreader is low-profile, so it'll fit under big air coolers, which is a genuine plus.

vs Competition
Against something like the Crucial Pro Overclocking CP2K16G64C32U5B, which gives you two sticks for dual-channel, the Viper Elite II is at a real disadvantage. The Kingston FURY Beast and Corsair VENGEANCE kits are DDR5, so they're not direct competitors if you're on an older platform, but they show how far memory has moved. For DDR4 users, a 2x8GB kit at 3200 or 3600 with tighter timings will almost always beat this single 16GB stick in real-world performance.

Price
Value & Pricing
Hard to judge value without a solid price, but the affordability percentile is dead last in our database. That means you're likely paying more for this single stick than you would for a comparable dual-channel kit. If you can find it cheap, it's a fine way to add capacity. If not, skip it.

Overview
The Patriot Viper Elite II is a single 16GB stick of DDR4 running at 3600 MT/s with CL20 timings. That's a weird combo. The speed is decent, but CL20 at 3600 is loose, and running one stick means you're leaving dual-channel bandwidth on the table. This is a budget-friendly way to get 16GB into an older DDR4 system, but it's not the performance play Patriot's marketing wants you to think it is.
Common Questions
Q: Will this work with my AMD Ryzen system?
Yes, it's compatible with both Intel and AMD DDR4 platforms. Just enable XMP in BIOS to hit the 3600 MT/s speed.
Q: Is one 16GB stick better than two 8GB sticks?
No. Two sticks run in dual-channel mode, which gives you roughly double the memory bandwidth. This single stick will bottleneck CPU performance in games and heavy workloads.
Q: Can I overclock this memory?
XMP 2.0 is supported, so you can hit the rated 3600 MT/s with one click. Beyond that, the CL20 timings don't leave much headroom for manual tuning.
Who Should Skip This
If you're building a gaming PC or doing any kind of memory-sensitive work, this isn't it. Go grab a 2x8GB or 2x16GB kit from Crucial or G.Skill instead. You'll get dual-channel bandwidth and tighter timings for similar or less money.
Verdict
The Patriot Viper Elite II is a single-stick solution for people who just need capacity and don't care about peak performance. If you're building a new DDR4 system or upgrading an existing one, get a dual-channel kit instead. This is a stopgap, not a foundation.
