Precision 7550 & 7750 Owners' Thread

WWAN antennas/cables will be included, as long as you purchase a display that says "WWAN" in the description. (Pay attention, there are for example two 4K display options, one with WWAN and one without.) It seems to matter more now with the all-aluminum lid; WWAN variants will include a bit of plastic at the top so that the antennas are not enclosed in aluminum.

Cards should be interoperable between systems/generations. The WWAN slot is just a B-key M.2/NGFF PCIe slot and you can install any card that fits in there. Dell doesn't whitelist NGFF cards. You could potentially upgrade to a 5G-capable WWAN card in the future, for example.

 

Thanks for the inputs. Appreciated.

However, I got the doubt as remembered reading somewhere that now-a-days if you do not order a Mobile Broadband card, the cables are missing. Possibly, the WWAN indicator is just tagged with the non-IR camera, and Dell does not bother to provide the cables from display to where the M.2 slot is unless the Mobile Broadband card is ordered along.

Though you are an encyclopedia, all doubts will be put to rest if someone with an actual piece with this configuration can share the status.

 

No surprise on the NFC and finterprint readers plugging into the same place. The Windows Device Manager tree looks like this. The device you listed is the Dell ControlVault device which on Windows has a driver provided by Dell (not Broadcom). Someone would have to come up with a Linux driver to interface with it. The device underneath it is the actual fingerprint sensor and it has a driver provided by Broadcom.

I don't know if this is what you're asking for, but on my quote, the screen "Item No" was 391-BFHY.

 

Another question for the Guru's. Does it make any sense to take the 8-core Xeon over the i9 if one is not taking ECC memory?

The Xeon does not cost very much over the i9, but adding ECC costs a bomb.

 

No, basically, ECC memory support is the only extra thing that the Xeon CPU brings to the table. The performance is the same. Core i9 actually might be more flexible with regards to overriding the power limits (less necessary in this generation than the previous since Dell bumped them up). So if you're not getting ECC memory or you don't think you'll ever upgrade to it, stick with the i9.

 

Hey guys, is Gskill SODIMM DDR4 64GB (2x32GB) Ripjaws 2666MHz CL18 1,2V a good choice for I9-10885h?
It's very, very cheap where I live (210EUR 23%VAT included).
Or maybe I should buy something better?

Furthermore Adata XPG S50 2TB drives (RGB LED ones) are actually very cheap lately. Are they OK?

 

I went i9... to avoid the ECC premium and gain access to XMP.

Update: supposed to start arriving next week. Not sure how long our IT team will take to muck things up, I mean deploy the standard Windows 10 image, before they hand it over.

I have XPG 8200 pro 2tb x4 in my 7750, works very well. The replacement unit came also with 8gb Adata 3200mhz ram which clocks at 2933mhz but I changed it to Kingston HyperX 2933 32GB x4. It’s working ok so far

Hello All,

Just wanted to inform that the Precision 7550 has now a valid competitor, the Lenovo Thinkpad P15

The laptop recently started to be available for sales

For just $3'809 you can configure the P15 with:
CPU:Intel® Xeon® W-10885M (2.40 GHz, up to 5.30 GHz with Turbo Boost, 8 Cores, 16 Threads, 16 MB Cache)
OS: Windows 10 Pro 64 for Workstations
Display: 15.6" UHD (3840 x 2160) OLED, anti-reflective, anti-smudge, touchscreen with Dolby Vision™, HDR 400, 500 nits
RAM: 32 GB DDR4 2933MHz (2 x 16 GB)
HDD: 1 TB PCIe SSD
Power adapter: 230W
GPU: NVIDIA® Quadro® RTX™ 5000 with Max-Q 16GB (capped at 90W)
Camera: IR & 720p HD
Fingerprint Reader
Wifi: Intel® Wi-Fi 6™ AX201 802.11AX (2 x 2) & Bluetooth® 5.1 with vPro™

https://www.lenovo.com/us/en/laptop...ThinkPad-P15-Mobile-Workstation/p/22WSP15P5N1

With the same specs, the 7550 would be about double the price, with RTX 5000 capped at 80W, without 4K touchscreen and without the 230W power adapter. Plus the PCH overheating issue which, by the way, should also be checked in the Lenovo P15 (I have no info on that).

Hopefully we will also see soon some real bechmark tests between them
