Is the 7550 graphic card upgradable?

Hello, I see you are looking for assistance. If you need our help, you could start a Private message with us and we will be happy to assist you.

Thank you for the help, I couldn’t have hoped for a better answer, now that I know that the GPU is replaceable I can be confident that this Laptop will be my partner for years. 

I know reviving a thread but this may be useful for someone. I upgraded a quadro t2000 to a RTX 3000 in my precision 7550. it required pulling out the mainboard to get to the GPU module. The key thing is that there is a black sticker on the heatsink for the quadro t2000's smaller die that has to be removed in order for the heatsink to make proper contact (and it does 60-75c under full load). When screwing the screws into the DGFF connectors make sure it is TIGHT otherwise you will only get x8 speed or internal + usb c display outs will not work. So if anyone comes across this in the future go ahead swap the cards! 

Now if anyone is daring enough to swap in a card from a 7560 I would be interested. 

Once I got past those issues it works well as a cheap gaming laptop. (I know quados are not the best for it but can not beat the results, beats my undercooled gtx 1080 in my old desktop)

@Crazycatboyz​ which cpu do you have? (and the thread breathes life lol)

Hi - ive just bought on of these. An initial question.... ive got a 4TB NVME drive - can i put this in as i noticed some review have mentioned 2tb drives as a max...? Thanks.

@Comfy

2tb is max.​

@Comfy​ 2tb is maximum

@Crazycatboyz​ I tried to upgrade an Intel UHD graphics card to a RTX 3000 in my precision 7550 and placed three  DGFF connectors but I could not turn on the laptop, any idea what went wrong?

@syknguyen​ odds are the DGFF connectors might not be screwed down tight enough, that was an issue on mine initially, other thing is make sure every connector is connected securely the ZIF connectors might not be lined up properly. past that I have no idea, there is a chance that the card is defective.   

@driv3r​ my email decided to send everything to junk for some period of time so I did not see this. my full specs just to get them out there:

i7-10750H (to the right of the image) 

64GB (2x 32GB)

initially Quadro t2000 but currently RTX 3000 (on the left of the image)

the 3 DGFF connectors are in the middle and on the other side (under the keyboard) there is a power connector 

I added a WWAN to usb converter for a mouse dongle 

x1 2TB NVME and x2 500GB NVME drives

the oddly rare 1080p touch panel for this laptop with IR Camera

@Crazycatboyz​ also forgot to add to my own post (and no edit since I posted again) check the power connector under the keyboard!

does anyone know if the newer rtx A4000 card will also work in the 7550? it seems to have a lot better specs than the rtx 4000.

@Crazycatboyz​ Great. Do you think the heatsink for a T1000 would work for a T4000
