Dell Pro Max 16/18 Plus (2025 model) pre-release discussion — MB16250, MB18250

I am skeptical as to whether the design of sandwiching the heat spreader between the CPU and GPU is truly effective.

 

Another interesting point is that the power board for the 48V regulator has been designed as a daughter board.

The "c" in cSODIMM stand for CAMM, or more precisely, "CAMM-based SODIMM".

That's not true; there are two types of DIMM form factors: CUDIMMs and CSODIMMs. The "C" stands for "Clocked," indicating that there are clock drivers on the DIMM board.

I believe it is guided by EU regulations.

that is true with a very big distinction, 

cSODIMM (CAMM-based SODIMM) = Laptop DDR5 SODIMM

cUDIMM (CAMM-based UDIMM) = Desktop DDR5 UDIMM

both are still essentially a CAMM adapter/interposer that allows you to plug in SODIMM modules into a CAMM memory slot, both of which are Dell-specific (and somewhat confusing) terminologies built around the CAMM platform.

Just check out this link, and you'll get a better idea of what they truly are.

@yslalan

In JEDEC-standard terminology you are correct, the “C” in CSODIMM and CUDIMM stands for “Clocked”,
referring to the presence of a Client Clock Driver (CKD).

In Dell/OEM usage, "cSODIMM" has also been used to mean "CAMM-based SODIMM",
which adds to the confusion, but is technically inaccurate by JEDEC standards.

And the "c" has nothing to do with the CKD, it's all about the CAMM slot interface.

JEDEC-CAMM does not affect the standard UDIMM and SODIMM slots. The "C" simply represents "clock" and is not related to CAMM. As for the CKD Small Outline DIMM (CSO-DIMM), here is the link from JEDEC.org for you to check.

The CSODIMM referenced in Dell's tech specifications is the one outlined by JEDEC, which has been updated to support high frequencies of up to 6400MHz.

simple decision, get a Precision platform while you still can.

i have a 7760 and it's 4 years, i still have 1 year on accidental. i dont think 7780 is an upgrade unfortunately, as i am mostly looking for newer cpu's... ideally i'd want them to use and, but u know...  but tb5 for docks, sounds nice and maybe worth it

What is the vertical screen resolution of the 18" screen in pixels (not just saying QHD+). Is it 1400, 1600 or some higher resolution?

 2560x1600 i think?

indeed, i read up on that link, you just quoted my response before i re-edited it.

its somewhat of a 30% upgrade id say between the cpu and the gpu overall,
it would been nice if intel didn't completely messed up 14 gen line and dell at least integrated with the 14900 for the last precision gen,
but it still be lagging way behind the 285H or the 5090/6000 you could (potentially) fit in it now,
still I'd grab a 7780 over the newer 18 pro max plus which im about to do to replace a 7770.

main issue for me is 5 year accidental. with 7760, they been here 5 or 6 times now replacing this godIO&*&%^&%^&& keyboard....  paint peeling, keys stop working, so.... ya, 

 

i mean, if 7780 goes on clearance next year, ill consider it, but right now. i may just keep using this and my razor which has 3090 and 13th gen cpu

Буква «c» в слове cSODIMM означает CAMM, а точнее «SODIMM на основе CAMM».

Это не новый стандарт памяти — это стандартные модули SODIMM, установленные на промежуточной или преобразовательной плате, которая вставляется в разъем CAMM.

Dell разработала эту технологию, чтобы обеспечить обратную совместимость с обычными модулями SODIMM DDR5 на материнских платах, предназначенных для CAMM — в основном потому, что JEDEC одобрила CAMM2 в качестве будущего, но большинство пользователей по-прежнему полагаются на SODIMM.

как я уже упоминал выше, Camm на самом деле еще не работает над этими платами, на данный момент времени Camm в основном теоретический и больше похож на маркетинговую шумиху, SoDimm работает так же быстро, как модули Camm на той же системе, и может работать с высокой плотностью стиков, и они лучше рассеивают тепло, но Dell не хочет, чтобы люди знали, так как они изначально были настроены на продвижение модулей camm, пока не поняли, что некоторые из нас образованы и Не судите о маркетинговой шумихе только по обложке.

 

edit:
важно отметить, что модули Camm дороже, чем модули Sodimm, и в этом формате нет никакой реальной пользы.

@Dell-Mano_G Hello, the ProMax-Plus series has finally been released. Is it possible to share any information regarding the TDP and TGP?

 

On the spec sheet, it indicates a 256G DRAM option. Will the 256GB CAMM (2x128 GB) be released to the market, and does that setup include 2 CAMM slots as mentioned in the spec sheet?

[SvenC]

CSoDimm 64 GB 418€ - thats the first time that the upgrade price from Dell from 16 to 64GB is not that much of an issue with 474€ - maybe a step in the right direction.

 

We'll see how Dell behaves if the CSoDimm prices drop - SO-DIMM 64 GB is around 160€ and less.
