Lenovo 32GB DDR4-3200 CL11 RDIMM (4X71B67861)
The 3200 MT/s speed and ECC error correction provide reliable data integrity for critical server operations. Its registered design and 1.35V power draw ensure stable scalability when populating multiple DIMM slots in a single system. This module is best for IT administrators upgrading a Lenovo server or workstation that demands consistent uptime for virtualization and database management.
概要
The 30-Second Version
Top-tier ECC server memory with the best latency we've ever recorded. If you need RDIMMs, this is the one to beat.
Pros & Cons
長所
- Best-in-class latency at CL11 100th
- ECC and registered for real server stability 90th
- 32GB on a single stick leaves room to grow 71st
- Strong feature set for the price
短所
- Not cheap, affordability is mediocre
- Useless for laptops or standard desktops
- DDR4, so no good for DDR5-only boards
- Zero customer reviews to lean on
実証データ
Performance
The CL11 latency is the star of the show. We're talking 100th percentile, the absolute best we've seen. That's not marketing fluff, that's our database talking. The 3200 MT/s speed is solidly middle of the pack, but for ECC RDIMMs, stability matters more than raw bandwidth. The 32GB capacity is above average, and the feature set, ECC plus registered, is a standout. Just don't expect this to do anything for a laptop. Our laptop score for this thing is a sad 51.4 out of 100.

vs Competition
The competitors listed, Corsair Vengeance, Kingston FURY Beast, G.Skill Trident Z5, Crucial Pro, KLEVV CRAS V, are all DDR5 desktop kits. They're faster on paper, but they're not ECC RDIMMs. Comparing this Lenovo stick to those is like comparing a work truck to a sports car. Different jobs. If you're building a gaming rig, get the G.Skill or Corsair. If you're building a server that can't afford a memory error, this Lenovo is the only one in the list that actually fits the bill.

Value & Pricing
At around 355 USD, this isn't a budget stick. Affordability sits at the 35th percentile, so you're paying for the ECC and the latency. If you need registered ECC memory, this is a fair price for what you get. If you don't need ECC, you're wasting your money. Go buy a standard DDR4 kit and save a pile of cash.

詳細情報
Overview
This is a server memory stick, plain and simple. The Lenovo 4X71B67861 is a 32GB DDR4 3200MHz ECC RDIMM, and if you're building or upgrading a workstation or server that needs registered ECC memory, this is a serious contender. The headline here is the latency. CL11 at 3200 MT/s puts it at the absolute top of our database for latency, which is a big deal for memory-bound server workloads.
Common Questions
Q: Will this work in my gaming PC?
Almost certainly not. This is registered ECC memory for servers and workstations. Your gaming motherboard almost definitely doesn't support RDIMMs. Check your board's memory QVL before you buy.
Q: Can I mix this with non-ECC memory?
No. Don't do that. ECC and non-ECC memory don't play well together, and registered and unregistered DIMMs are completely different beasts. Stick to one type per system.
Q: Is 32GB enough for a server?
For a lot of small business servers and home labs, yes. And since it's a single stick, you've got room to add more later. Just make sure your board has the slots and supports the total capacity you're aiming for.
Who Should Skip This
If you're building a gaming PC or a standard desktop, this isn't for you. Go get a DDR4 or DDR5 non-ECC kit from Corsair or G.Skill instead. You'll get more speed for less money and you won't be paying for error correction you'll never use.
Verdict
If your server or workstation needs registered ECC DDR4, buy this. The CL11 latency is genuinely exceptional, and 32GB per stick is a sweet spot for capacity. It's not cheap, and it's not for everyone, but for the right machine, it's a no-brainer.
