JEDEC Confirms CAMM2 Memory For Desktop PCs: DDR6 Up To 17.6 Gbps & LPDDR6 Up To 14.4 Gbps

DDR6 & LPDDR6 memory will feature super-fast speeds of up to 17.6 Gbps while the CAMM2 DRAM standard is headed to desktops.

Desktop motherboards with DDR6 in 2026 or 2027 will use new memory standard CAMM2, mean DDR5 will be the memory stick to see the end of DIMM memory standard.

Wonder how hit is going fit onto future desktop boards, probably a breakout board of some sort? The standard DIMM slots don't take up much room.

I thought about that, maybe CAMM2 will fit on the back of motherboard on former DIMM site.

Looks like MSI will be showcasing their Project Zero board at computex with the new CAMM2 memory "slot" if you can call it that. Looks okay on a board with all the connectors on the rear but still can't see this happening on a regular board. Imagine how it would work on a Matx or even itx board.

Next Crop of MSI Project Zero Motherboards to Implement CAMM2 DDR5 Memory

The CAMM2 and LPCAMM2 form-factors were originally designed for thin-and-light notebooks, to provide them with memory replacements/upgrades without compromising on the Z-Height tolerances of the device's design. It looks like MSI sees a future for the CAMM2 form-factor on desktops, specifically...

I looked at CAMM2 desktop prototype and compared to DIMM, noticed CAMM2 length is about 40% smaller than DIMM slot length and CAMM2 wide is the same size as 3 DIMM slots, smaller than 4 DIMM slots size. CAMM2 on riser card or slim CAMM2 could work fine on MATX and ITX board.

I'd be amazed if we got DDR6 in 2026 considering JEDEC are due to ratify their updated DDR5 standard in Q2 next year. I can see 2028 but 2026 seems way too early.

No 2028 is very long time away.

I googled LPDDR6 found JEDEC will publish LPDDR6 final spec in Q3 2024.

LPDDR6 Memory To Power Next-Gen Devices: JEDEC To Finalize Standard By Q3 2024

JEDEC is expected to finalize the specifications of the next-gen LPDDR6 memory by the third quarter of 2024.

wccftech.com

It seemed both LPDDR6 and DDR6 was completed development that already met JEDEC planned final spec many months before launch date.

LPDDR6 will launch in 2025 and DDR6 should launch in 2026, it all make sense.

This wont be coming to desktops anytime soon, if ever......look at the MSI board picture, it takes up more than 4 slots of space now, people are forgetting about 1 DPC boards (mATX and ITX) theres no room for it.

I now managed to measured ATX connector, it is about 50mm length with 24 pins. So Kingston Fury desktop CAMM2 prototype wide size is about 40mm aligned to ATX connector's 20 pins, CAMM2 length is about 80mm. That is much smaller than DDR5 DIMM slot length 150mm and 4 DIMM slots wide size is about 40mm.

Yep it will absolutely certainly fit in MATX motherboards which all has 4 DIMM slots as standard like Z790M AORUS ELITE AX:

Kingston Fury desktop CAMM2 prototype could theoretical fit in ITX motherboard like Z790I AORUS ULTRA if all ATX and SATA3 connectors moved to back of motherboard or use small laptop CAMM2 module or maybe CAMM2 memory riser?

Interesting! Look like CAMM2 will fit on ITX motherboard if ATX and SATA3 connectors moved to back of motherboard.

Users can connect ATX power connector and SATA3 cables at back of case.

ASRock Displays 13 Z890 Motherboards Ready For Intel Arrow Lake CPUs: Aqua, Taichi, OC Formula, Nova, CAMM2 Designs

ASRock has just displayed 13 new Intel Z890 motherboards ready for Arrow Lake CPUs such as Aqua, Taichi, OC Formula & CAMM2 designs.

wccftech.com

CAMM2 memory sit on about 10mm above CAMM connector height will have around 80mm X 60mm of huge empty space on motherboards.

CAMM2 memory will come to desktop later in 2024, ASRock will launch OC Formula Z890 motherboard feature CAMM2 memory.

Asus board with camm2 ddr5 running at 7500mhz, Asus claim under 50c temps

No it not running at 7500MHz, actually it running at 8000Mhz and temp is 41C.

41C!!! Wow that incredible without memory heatsink, my GSKill DDR4 3200MHz has RGB heatsinks and temp is about 45C. I googled DDR5 8000MHz temp found someone got GSKill sticks with heatsinks got high temp at 62C so without heatsink temp probably could be about 72C.

If Kingston Fury CAMM2 has heatsink on then temp would be about 31C.

 

[AthlonXP1800]

Wow thats very low temps based on the voltage that would be needed for 8000; part of that will be because its an open bench and an airconditioned building - so maybe add 10c if you're at home in a hot room with bad airflow, but even at 50c that would be low considering it has zero heatsink and relies completely on passive cooling and case airflow. The old UDIMM memory slots we currently use are very flow restrictive, there can be easily 10c difference in temps between my memory sticks and thats due to airflow, but when the memory full flat like that it wont block airflow at all. And you get some CPU coolers that specifically blow air around the base to cool VRMs and these will now also cool the memory as well with the CAMM2 layout

So not only are we saving space with CAMM2 but memory will run cooler

Yes it was tested on an open bench, it probably very warm in an airconditioned building at Computex now, I checked Taipei weather it was very hot 32C today so there was no picture of ASUS test motherboard but I found a picture from GSkill showroom showed off GSKill Ripjaws CAMM2 DDR5 memory running at 7800MHz on ASUS Z790 Hero motherboard but it did not displayed temp. The test board had CPU air cooler and a 120mm fan both blowed air on CAMM2 memory.

It looks like camm2 is potentially also faster and more stable than udimm. Motherboard makers claim camm2 shortens the traces

Yes and CAMM2 probably running at very low temp compared to UDIMM running at very high temp. It is cold day 8C here in Scotland tonight and I checked my RAM temp are now 36C.

I guess DDR5 CAMM2 really dont need heatsink and fan blow air on cold day. CAMM2 temp on cold day could be about 25C without heatsink and maybe 15C with heatsink.
