Hey folks,

I came across something odd while comparing two DDR5 RAM kits — both listed as 64GB (2x32GB), CL30, and rated at 6000, but with different terminologies: one is marketed as 6000MHz, the other as 6000MT/s.

Example kits for reference:

• Corsair Vengeance – 64GB (2x32GB), 6000MHz, DDR5, CL30 – CMK64GX5M2B6000C30
• Kingston Fury Beast XMP – 64GB (2x32GB), 6000MT/s, DDR5, CL30 – KF560C30BBK2-64

Now, I know that technically MT/s (mega transfers per second) is the correct term for modern memory, and MHz is often just marketing or shorthand — especially since DDR stands for "Double Data Rate." But what confuses me is the number of people (in forums, videos, etc.) who claim that something like "6000MHz" is misleading and could actually mean 3000MHz real clock, equating to 6000MT/s effective rate. Others say both terms are interchangeable in these contexts.

So I wanted to open this up for a technical discussion:

• Is there any meaningful difference between these two labels — 6000MHz and 6000MT/s — when used in marketing materials for DDR5?
• Is it safe to assume they represent the same effective speed when the CAS latency and timings are also the same (e.g. CL30)?
• Are there vendor-specific behaviors (e.g. with Corsair vs Kingston) that affect how XMP profiles behave, even if the advertised specs are identical?

This seems like a subtle but important distinction, especially for people comparing RAM kits for performance-sensitive tasks. Curious to hear from others who’ve looked deeper into this or had real-world experience comparing similarly specced kits with different labels.
