Precision 7550 & 7750 Owners' Thread

Suspicious.
It looks like the cable length is different but that might not matter, as long as you do not get one that is too short, you might be able to just "pack it in" and make it work.
The connector end looks the same but the manual shows a pin in the middle while the other picture does not; I am not sure if that middle pin is important in the newer systems.

It would be best if someone who has a 7750 could either find the D/PN on the cable directly, or check their system configuration details in the order from Dell and see if they can pull out the DGFF power cable part number.

[Edit]
Found this one that looks closer but still not quite right. It looks too long and the position of that funny block red/wire thing could be problematic. It is for 7730/7740.

It's here.

It is an "optimal for enterprise" / "production branch" release.

 

Much obliged. Just installed it; saw no real performance improvement in CP2077.

 

Guys I got green light for my new Precision (it's hard when your wife is also your boss
I want it with i7-10875 or I9-10885H and RTX4000.
But I wonder - is getting a 17" is worth it? I'd need to change all of my bags, as I travel with my laptop A LOT. And only benefit I can see is 30W more powerful GPU.
I also don't have much time to decide, as I need it ASAP.

 

Only you can decide that: do you need the extra screen space? Perhaps you work on photos, or are a programmer, and need to see more lines of code? Is the bag trade-off worth that space? All questions you've got to answer!

The 17" model is heavier, but also has proportionately more cooling performance. Again, whether or not that extra 20 W (Dell has issued a 90 W VBIOS update for the 7550 now) of GPU performance is important, can only be decided by you. Do you game a lot, or run CUDA on your notebook, or render videos/3D graphics or something?

 

I work with 3D scanning, Additive manufacturing and revierse engineering. So lots of CAD, mesh manipulation software.
I asked myself those questions and I think I've decided on 17". I'll lose my beloved bags and backpacks, but if the performance is there...

Last question is i7-10875 vs I9-10885H. Os there noticeable performance difference? It's 200EUR update. I could get second 2TB NVMe for that.
I need a LOT of horsepower. So much my scanners don't even work properly with my Precision 3520. I'm now carrying my home PC with me (R5 1600/32GB/RTX 2080TI) with 27" inch monitor. It's a chore. And CPU is a little to weak. GPU is mostly bored yo death, but sometimes I need like 6GB of VRAM to hold the models (200mln point clouds are normal thing).

 

Wow, that's a <$100 upgrade on the US side. Anyway, it is a small performance difference (which may be fully negated once the system starts throttling), but... You have the opportunity to add another NVMe drive at any time in the future (and they're getting cheaper!), whereas CPU upgrades are not possible (without sourcing and swapping out the entire motherboard).

I really like the 17" form factor myself... aside from the extra cooling potential, the larger screen is just nice to have on the go. Worth the weight trade-off for me, for sure. As for your bags, unless the 15" system goes in a "compartment" with a very specific fit, you might find that you can cram a 17" in there. With the 7750, Dell has done a bit of slimming things up so it's not quite as large as prior 17" systems. I use a backpack-style carrying case with my M6700, and it was not designed for a 17" system but I don't have a problem fitting the laptop in there.

 

My bags are Helikon Large Messenger (My Precision 3520 fits tightly in laptop compartment), Think Tank Urban Disguise 50 V2 (3520 was bit to large, 7550 would be perfect, 7750 won't fit).
I think I'll order Timbuk2 bag with Dell and go from that.
Urban Disquise 50 is great photo bag and it now houses two of my 3D scanners with wires, accessories and PSU. So I'm ok with that.
What I'm seeing 7750 is only 2.5cm longer than 3520 and oter dimensions are comparable:

So I'll go with it.
I'm oridering 2x32GB 2933MHz CL17 Hyperx's and SX8200Pro 2TB - lots of cash saved compared to Dell's stuff. It'll be less than 4k EUR incl tax.

 

My 7750 fits in 15 inch laptop bag and sleeve. I'd go with 7750 if I were you - larger screen, better cooling.

 

You can. I bought mine with Ubuntu from Dell UK site, just checked and nothing has chanced.
