Overclocking is always fun and almost everyone can do it, however, when it comes to extreme overclocking, there are only a handful of persons doing it. Today, a Chinese extreme overclocker "baby-j" has managed to establish a new world record frequency with his Crucial Ballistix Max DDR4-4000 (BLM16G40C18U4B.M8FB1) memory kit. Using liquid nitrogen (LN2) cooling for the DIMMs, the overclocker managed to push the memory kit to an amazing 7004.2 MHz, making it the world's highest frequency hit on DDR4 memory. What is more amazing is the fact that the platform used for the new record-setting overclock, is based on AMD's B550 motherboards running with AMD Ryzen 5 PRO 4650G processor, which seems to have a very good memory controller. The timings were a bit relaxed with them running at 22-26-26-46-127-1 (tCAS-tRC-tRP-tRAS-tCS-tCR) settings.

Nice to see that someone noticed that other IC than Samsung B or Micron E can overclock too :)

... I can always share my DDR4-5656 on the same IC and full air cooling from a couple of days ago ;)
and 2x16GB at DDR4-5426 CL18, probably stable but I had no time for long tests

The picture of the system isn't of the actual system used in this submission
The board in this pic is a Maximus IV Gene LGA1155 DDR3 with a GTX580... Quite old

That was a good catch ! You noticed correct about the board being different !

But that is not a Maximus IV Gene, it is a Crosshair V Formula, note the red detail protruding from the heatsink close to the I/O (and the rest of layout belongs to this board)

More evidence of what i've been reading, the IMC in Renoir is indeed a beast.

Can anyone find an overclocking guide for these RAM modules?

I have the same kit in RGB and have managed to get them to 4300, but it becomes a bit unstable past this.

Love these modules though :)

You don't need any guide, just good motherboard and CPU with strong IMC (even average will reach DDR4-4800). Setting something like 18-24-24 1.55V and everything else at auto is enough to reach DDR4-5000+ ... as long as the CPU and motherboard handle that. Have to play a bit more for a higher clock but for daily work and gaming it can be waste of time.

Shame 2x16GB Crucial kits are barely sold here in the Netherlands, it's mainly G.Skill and Corsair.

Check Amazon DE, overclockers.co.uk or some other stores in EU... or even Crucial store. They are all shipping this memory to most countries. However, these modules are quite expensive.

Nice job, if nothing but to show these sticks can go way above rated speeds, however, that cooling set-up is obviously not practical for the everyday user...
