Today, we're checking out the Patriot Viper Venom DDR5 RAM, specifically a 64GB kit spread across two sticks. This is more of a simple, lower-cost kit, but it comes with features and functionality that make it straightforward and easy to use.

While this RAM should work fine with Intel 12th gen or later with DDR5 based motherboards, or older AMD AM5 setups like the 7000 series CPUs, my focus here is primarily on using it with AMD 9000 Series CPUs and the configuration related to that platform on an X670E motherboard.

Installation Considerations
Before you install any RAM, it's a good idea to look at your motherboard manual. Make sure you know which slots should be populated first for your specific motherboard. Putting the sticks in the right slots allows them to function correctly in dual-channel mode.
For AM5 AMD 7000 and 9000 series CPUs and motherboards of that generation, it's generally recommended to stick with just two sticks of RAM.
If you try to populate all four slots, you'll likely have to run the RAM significantly lower than the rated memory speed. So something like 4800 instead of 5600 MT/s. At least at the time of this writing, if you want the most RAM at the fastest speed possible then go for a 96 GB kit that is split into two sticks.
I honestly wish I would have spent more to get a larger 96 GB kit, but I have been experimenting with AI LLMs which can have massive RAM requirements. Otherwise there are not many use cases that need even 64 GB.

Configuration in BIOS
Once the RAM is physically installed, the next step is to head into your motherboard's BIOS. You'll want to enable a profile to get the rated speeds. Since I'm using an AMD platform, I enabled the AMD EXPO settings. If you're using Intel, you'd look for the XMP setting. My motherboard actually showed options for both, but using EXPO makes the most sense here.

Key Specifications and Timings
With the AMD EXPO profile enabled, the important specifications for this particular kit are:
- Speed: 5,600 mega-transfers per second (MT/s)
- CAS Latency (CL): CL40
- Primary Timings: 40-40-40-76
- Voltage: Around 1.35 volts (my system reported slightly under this)
My motherboard BIOS revealed a massive amount of detailed timing settings that get configured by the EXPO profile. You can see the main timings, sub-timings, turnaround timing configurations, and miscellaneous settings on screen in the video if you need to verify specific values.

Aesthetics and Build
I specifically chose a RAM kit that didn't have RGB lighting. Honestly, the overall look of this kit isn't particularly exciting. I personally would have preferred a straight black design without the extra white and red accents, but it's fine. The modules do include heat spreaders so that's a plus.

Testing and Reliability
After getting the system set up and configured, I ran MemTest86 to check for stability and errors. The RAM passed the tests without any issues, confirming it's functional. So far, I haven't encountered any problems with it in regular day to day use.

Why This Kit?
If you're trying to build a system while being more budget-conscious, but you also need a larger amount of RAM, this kit strikes a pretty decent balance. In my case, I do a lot of creative work like photo editing and video editing, where having more RAM capacity is often more beneficial than having slightly faster RAM with less capacity. I'd prefer having 64 GB of reasonably fast memory like this over, say, 32 GB or 16 GB of extremely fast memory.

Final Thoughts
This Patriot Viper Venom DDR5 kit isn't necessarily anything groundbreaking or special, but it does what it's supposed to do. It functions reliably, it was very easy to install and configure using the EXPO profile, and it provides a good amount of memory for the cost. For users like me who prioritize capacity for creative tasks or heavy multitasking without needing bleeding-edge speeds, it's a solid option. No complaints here.
