The proof
Performance
6400 MT/s at CL32 is a strong combo. Latency sits at the 88th percentile, which means it's snappier than most kits in our database. The 32-38-38-76 timings are tight enough for gaming and light workstation use. On-die ECC and a PMIC help keep things stable, and the 1.88mm aluminum heat spreader does its job. One thing to note: several owners mention that populating all four DIMM slots at high frequencies gets finicky. Stick to two sticks if you want the rated speed without headaches.

vs Competition
Against the Corsair VENGEANCE RGB CMH64GX5M2Y6400C32, you're getting half the capacity for similar money, which stings. The G.Skill Trident Z5 Royal runs at 6000 MT/s with tighter CL26 timings, so it trades a bit of bandwidth for lower latency. The Kingston FURY Beast KF564C32BWEAK2-64 gives you 64GB at the same speed, which makes more sense if you need capacity. The Crucial Pro Overclocking CP2K16G64C32U5B is the closest spec match, but without the RGB tax. Lexar holds its own on features and speed, but the current price makes the competition look more attractive.

Price
Value & Pricing
Here's the awkward part. This kit was a fantastic deal before RAM prices went nuts. Now it's listed around $880 USD in the US, which is hard to swallow for 32GB. Owners who bought early rave about the value. Buyers today are paying a premium. If you can find it closer to its pre-hike price, it's a no-brainer. At current rates, you're paying for scarcity more than performance.

Overview
The Lexar ARES Gen2 RGB is a 32GB DDR5 kit running at 6400 MT/s with CL32 timings. That's a sweet spot for AMD and Intel builds right now. It supports both XMP 3.0 and EXPO, so setup is basically one click in BIOS and you're done.
Our database puts this kit's feature set at the 99th percentile. Speed lands at 95th. It's not the absolute fastest DDR5 out there, but it's close enough that most people won't notice the difference. The RGB is there if you want it, though owners say it's not exactly blinding.
Common Questions
Q: Will this RAM work with my AMD motherboard?
Yes. It supports AMD EXPO, so you can enable the 6400 MT/s profile directly in BIOS. Just make sure your board supports DDR5 and check the QVL list for compatibility.
Q: Can I run four sticks of this RAM at 6400 MT/s?
It's possible, but several owners report stability issues when populating all four slots at high frequencies. You may need to drop the speed or loosen timings to get four sticks stable.
Q: Is the RGB lighting bright?
It's visible and syncs through Lexar RGB Sync, but multiple owners say it's not particularly bright. If you want aggressive lighting, you might be underwhelmed.
Who Should Skip This
Skip this if you need 64GB or more. At current prices, you can get a 64GB kit from Kingston or Corsair for similar money. Also skip it if you're planning a four-DIMM setup, since owners report frequency drops when all slots are populated. And if RGB brightness matters to you, this isn't the kit to show off.
Verdict
If you're building a gaming rig or a workstation and want fast, stable DDR5 with minimal fuss, this kit delivers. The 6400 MT/s CL32 spec is excellent, and setup is painless. Just don't expect the RGB to light up your room. Buy it if you can find it at a sane price. If you're paying current market rates, you might want to look at 64GB alternatives that cost about the same.
