Corsair CMK32GX5M2B6000C36 Review
The Corsair CMK32GX5M2B6000C36 is a 32GB (2x16GB) DDR5-6000 desktop memory kit rated CL36, for a true latency of 12ns.
Speed and Latency
True latency is CAS latency divided by half the transfer rate: 36 / (6000 / 2) x 1000 = 12ns. 68% of the desktop DDR5 kits we list are as tight or tighter, so this is on the looser side of its class.
Platform Fit
This is for DDR5 desktops: AMD AM5 on 600 or 800 series chipsets, and Intel 600, 700 or 800 series boards with DDR5 slots. It physically will not go into a DDR4 board. On AM5, 6000MT/s keeps the memory controller at a 1:1 ratio, which is why it is the go-to speed for Ryzen 7000 and 9000. Profiles: XMP 3.0.
Capacity and Configuration
The two 16GB modules give you dual channel with two slots used. If you might want more memory later, buy the bigger two-stick kit now. Four DDR5 modules rarely hold their rated speed. At 32GB you have room for gaming, streaming and editing without running short.
Build and Cooling
Corsair lists no module height. If you run a large tower cooler, check its RAM clearance first. Corsair does not disclose which memory chips are used, which matters mainly if you plan to tune timings by hand.
Speed Score
It scores 7.3 out of 10 on our DDR5 Speed Score, which weighs transfer rate and true latency against every other DDR5 kit we list. Do not compare it with DDR4 scores.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- AM5 builds that want the 6000MT/s 1:1 sweet spot
Not for
- Latency-focused builds: 68% of desktop DDR5 kits are as tight or tighter
- Manual timing tuning: memory chips are not disclosed
- Adding a second kit later for four sticks

FAQs
Is the Corsair CMK32GX5M2B6000C36 compatible with my motherboard?
It fits DDR5 desktop boards (AMD AM5, Intel 600, 700 and 800 series with DDR5 slots). It does not fit DDR4 boards.
How fast is CL36 at 6000MT/s in real terms?
It works out to 12ns true latency. That is tighter than 32% of the desktop DDR5 kits we list.
Can I add a second kit later for four sticks?
It is not recommended. Four DDR5 sticks usually run well below their rated speed. Buy the total capacity you need as one two-stick kit.
Is 6000MT/s good for AMD Ryzen 7000 and 9000?
Yes. 6000MT/s lets the memory controller run 1:1 with the memory on AM5, the best balance of speed and latency.
