MSI OC team Breaches 10K MHz DDR5-10004
MSI OC Team just announced the overclocking of Kingston Fury Beast DDR5 RAM to DDR5-10004.
The team used an MSI UNIFY-X motherboard equipped with a Core i9-12900KS CPU running at 425 MHz. At 5001.8 MHz, the memory has a timing of 72-126-126-126-127-2, which is required for 10004 MT/s.
MSI and Kingston have a long history of co-developing memory optimization and overclocking technologies. MSI even throws in a 6000 MT/s Kingston RAM kit with their MEG Z690 GODLIKE motherboard. Memory manufacturers have suggested that they intend to introduce 10-12 GT/s memory in the future.

which is required for 10004 MT/s
It's Mbps not MT/s.
Only Micron uses MT/s, which is inaccurate because it doesn't actually do that many transfers per second. Each "Transfer" contains a number of bits, when you multiply the Transfers per second against the bits per transfer, you get the bitrate, which this the rated speed of the device. A DDR4 4000 kit does not do four thousand transfers per second, but it does have a bitrate of four thousand per second.
Every other manufacturer on the face of the earth that makes data storage devices, volatile or non-volatile, uses Bitrate per second to indicate speed, not Transfers per second, for the aforementioned reasons above.
I think Buildzoid did a good video on this, if a bit of a ramble:
Edit: Apparently it's not even consistent within Micron itself since every other division uses Bitrate except Micron's DDR division.
Edit2: Yes, this effectively means MSI reached 10 Gbps on DDR5

MT refers to mega tranfer, as in million transfers, ddr memory performs 2 tranfers per cycle, known as double data rate, which is why the the MT/s is double to real clock speed of ddr memory,
its not just used for memory either.
on amd platforms the hypertransport bus speed was often given in MT/s
the term is technically accurate.
the math goes as follows
( tranfers per sec) x (bus width) / (8 bits per byte) = total bytes per sec
example : 4000mt/s x 64bits (width of a memory stick) / 8 = 32000 MB/s (this number is also used as a speed rating for memory modules in the form of PC4-32000 )
mbps is an equivalent term, but instead refers to the speed per data pin when talking about memory chips. resulting in the same math for determining the total data rate
(bits per sec per pin) x (bus width) / 8 = total data rate per sec in bytes
both terms are fine to use, but I will say that MT/s has fallen out of use in recent years by the industry.

The latency is still better than in SSDs, so MSI must be happy.
