@ElCoyote_ good morning.

I have a problem with getting signal from NVidia Quadro p2200 - no signal goes out of it. I tried another GPU ( which known to work in a PC ) with the same result - no signal.

Have you ever experienced this type of a problem in your Dell T640? And if so, how did you fix it?

best regards,
Dmitry

Hi Dmitry,
What OS are you using?
Did you set the onboard video controller as disabled in the BIOS?

This is some great stuff! I too wanted to upgrade our T640 and I truly learned a lot here. Would you mind if you could share your CPU seller info in a dm? Can really use a reliable source. I am so tempted to buy a pair of 8272CLs from eBay but was scared by a one-star review that says:

Don't buy OEM unless you have after market motherboard
Very limited compatibility

I think I'll probably order the 8269CY like you did. Besides the fact that based on your test the 8272CL probably doesn't work on Dell in the first place, it was also quite sketchy to me that half of the 8272CLs from eBay were like ~$300 while the other half were ~$600

Hi All,
Mb this thead not is dead yet (i hope 4 this)
have question about T640, mb here someone can answer

i want to use T640 18xLFF like workstation in tower mode
spec like this - 2x4114, 64Gb for each cpu, 2x750w psu and video card like P4000

here question about manual
"""
Requires a GPU-ready chassis in a rack form factor (GPUs are only supported in rack mode). 3.5 inch x18 HDD chassis is not supported.
Dual PERC (x32) configuration is not supported. Fresh Air configuration is not supported.
"""

1 - is it real needed to be in rack mode ?
2 - why not to use 18xLFF ?
3 - is it a enough 2x750x for 18 HDD (orSSD) and 1 video card ?

There are things that the manual says that don't necessarily apply to the actual homelab application.

1) No, this is not needed. They only say this in case the customer wants to do 4 x 300W GPUs because the airflow is slightly better in Rack mode.
2) what's the question? I've used some quadros in both 18LFF and 16SFF+NVMe chassis..
3) 2x750W isn't enough for 18HDDs, go with 2x1100W if on 120V (North America).

BTW, GPUs with external power will require the PDU board (located underneath the main sysboard) and will cause the machine to start requiring the external fans (noisy).

Go for PCIe-slot power only if you can.

u help a lot! thx 4 this !

3 - 2x750 on 210-240v - what about this type ?

if i install PDU board and dont install ExFans - can it be turn off in BIOS (i mean warnings) or system will not start ?
Or mb we can make a plug for system board:
30 Fan connector (Ext R) Right external fan connector
39 Fan connector (Ext L) Right external fan connector
its from owner's manual (page 161)
like 4 system fans will be connected ?
