Even faster than DDR5 - Memory overclocking reaches 7Ghz

[williamcll]

It is known that currently the fastest speed that DDR5 offers out of the box is 6.4Ghz. Recently a user by the name of Baby-J managed to set a new world record in RAM speeds by pushing the single stick of crucial BALLISTIX MAX 4000 16GB to 7Ghz, surpassing the previous holder by 337.6Mhz

Chinese overclocker baby-j has established a new world record for memory frequency. The record-setter pushed Crucial's Ballistix Max DDR4-4000 (BLM16G40C18U4B.M8FB1) memory under liquid nitrogen (LN2) to 7,004.2 MHz, an impressive 75.1% overclock. The user's shared screenshots show a frequency of 7,006.4 MHz, however, the validated result points to 7,004.2 MHz. Crucial is no stranger to the big stage. The brand's Ballistix Max memory has become a favorite for extreme overclockers. The memory was instrumental in a previous world record where we saw the Ballistix Max hitting DDR4-6666 speeds. The setup from this occasion is a bit similar to the previous configuration.

For starters, both systems employed AMD's Ryzen 4000 (Renoir) desktop APUs, which have proven to have a very potent memory controller. The record-smashing system consisted of a Ryzen 5 Pro 4650G and MSI's newest overclocking-centric MEG B550 Unify-X motherboard. For the memory enthusiasts out there, the Ballistix Max DDR4-4000 memory used in the world record is a single-rank 16GB module. The module leverages Micron's B-die integrated circuits (ICs), and it's rated for DDR4-4000 at 1.35V. Crucial doesn't list the memory on its website, therefore, its primary timings are unknown. For the record, the overclocker obviously relaxed the timings to 22-26-26-46 (1T).

Thoughts: That is impressive. I can't imagine how fast RAM clocks could go if a current generation RAM could hit 7GHz. Maybe the10Ghz barrier would be broken in the foreseeable future.

well it seems like that he got a good silicon lottery on cpu too

out of the box vs. LN2 cooled lmfao

how can you even compare these?

what do you mean, the CPU is well within a "normal OC"

With a board nobody can buy yet, yay

the memory controller is built into the CPU, that has to be good to run memory so fast

did not think about that lol.

Which is why CPU is under LN2 pot and probably pumping insane voltage to the memory controller (usually SA aka System Agent) to even be able to keep up with such fast memory. And using a single stick, because dual, triple or quad channel setup puts extra burden on memory controller.

 

When I'll be blessed with ability to buy Ryzen 5000, I'll be happy if I can score 3700MHz memory for a relatively normal price...

I have this kit, OC's well. Being single rank 16gb per stick you can run it 1T and have 32gb of ram.

Well my DDR3 is doing just fine......

Cool. Retail highly clocked memory in general is so expensive it's insane. Can't wait to see new gen.
