G.Skill Trident Z5 Memory Overclocked to DDR5-9560 CL120 Using LN2
We recently reported on the DDR5-8888 CL88 Overclocking world record set by G.Skill, ASUS, and overclocker "lupin_no_musume" using G.Skill Trident Z5 DDR5 memory on an ASUS ROG Maximus Z690 APEX motherboard. This same overclocker has now set a new record using the same memory and motherboard combination achieving a speed of 4779.7 MHz (9560 MT/s) at 120-120-120-120-127-2 timings using liquid nitrogen cooling. The record was set with a single 16 GB Trident Z5 DDR5 memory module paired with an Intel Core i9-12900K processor.

1 Bit per Second = 1E-06 Megabit per Second (SI def.)
∴ 1 Megatransfers per Second = 64 Megabit per Second (SI def.)
∴ 9560 Megatransfers per Second = 611840 Megabit per Second (SI def.)

Bitrate stated in bits per second (Mbps, Gbps) seems to be the most common industry standard used by manufacturers to indicate the data rate "per pin/lane" in memory chips. There are some examples of MT/s being adopted lately instead, but historically megatransfers were often used to indicate the raw bandwidth (including encoding losses, like in older pci-e where 5GT/s gave 4Gbps). Well... A single channel of DDR5 is 32 bits of data, therefore it would only be 38.2GB/s (as opposed to 76.4 in 64bit scenario). Unfortunately it seems that "Dual channel" meaning four channels is going to be the norm when it comes to DDR5 (and supposedly eight in DDR6 :( ).
An 3600 DDR4 with CL16 has 8.8ns latency, you realize that this whole experiment is completelly useless.
Max. overclocking frequency example:
1DPC 1R Max speed up to 6666+ MHz
1DPC 2R Max speed up to 5600+ MHz
2DPC 1R Max speed up to 4000+ MHz
2DPC 2R Max speed up to 4000+ MHz
So a single DIMM should always attain the a higher frequency than 2 DIMMS.
Maybe they should have a 2 DIMM frequency record as well. :)
These records are usually just bragging rights has with most LN2 OC records. Running LN2 on your RAM is hardly practical for most people anyway. :laugh:
If I bought another brand other than MSI, would it not matter how many ram I installed?
