128G Ram in PowerEdge T140 possible?

Question

The Dell T140 takes 4 DIMMs (ECC UDIMMs or regular DIMMs). When the T140 was introduced, only 16G ECC UDIMM were available.

I'm considering the purchase of a T140 to replace a same-gen Precision T3431 that's already maxed out at 64G, I'd like to confirm if the T140 could go to 128G RAM with the appropriate processor.

Here's what worries me:

- my T3431 has a Xeon E-2246G, which is listed as having a Max of 128G on ark.intel.com. However, a dmidecode of the T3431 says this:

# dmidecode -t memory|head -12
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.1.1 present.

Handle 0x0009, DMI type 16, 23 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: Single-bit ECC
Maximum Capacity: 64 GB <==========================
Error Information Handle: Not Provided
Number Of Devices: 4

Does the T140 have the same kind of limitation? (Maxes out at 64G even though the Xeon might support up to 128G).

32G ECC UDIMM sticks are now available, which would allow for 128G total memory.

Any ideas?

T140 only support 8GB and 16GB DIMM and maximum memory supported on T140 is 64GB. Please refer below link for details.

As 32GB DIMM is not supported and not validated on T140, we can not guarantee that it will work.

Hi Shine,

Yes, I agree that the technical guide (written before 32G ECC UDIMM sticks became available) lists 64G RAM as the maximum. As much as Dell cannot tell if 32G sticks will work inside the T140, is there something -preventing- them from being used in a T140? I can deal with 'we cannot confirm if it will work because we haven't tested it' but I wanted to see if anything specifically prevented/denied 32G sticks from being used in the T140.

Hi,

Unfortunately, we do not have any documentation on the architecture of the server, which only allow support up to 16GB per slot. I'm unable to provide a solid answer if it's being prevented or blocked from using larger memory. I'm leaning more on it's main board limitation rather than it's being "disabled" to used larger memory.

If you check the Intel specs for the Xeon processors listed as POS options for the T140, some of them do support 128G RAM.

Thanks for replying but since you work for Dell, I think the answer that 'You don't have access to Documentation' is a little confusing (Or Dell as a company needs to review its internal processes to let you access documentation in order to provide help to end-users).

Hi, I'm afraid it's the way the product design is.... that does not allow what you are stating. I Sorry we can't be of further help this time.

Congratulations! I've just ordered 4 x 32G (HMAA4GU7AJR8N-WM) for my T140. Thank you for sharing, Vincent

Upgrade successful here as well (but you need a T140 with a Xeon Scalable 2nd gen cpu):

Obviously, this won't work if you have a T140 with a Celeron or a Core i3 (these max out at 64G according to Intel)

Hello I'd like to re-direct you to DELL-Shine K's reply above.

"T140 only support 8GB and 16GB DIMM and maximum memory supported on T140 is 64GB. Please refer below link for details.

https://dell.to/4gt0DMC

As 32GB DIMM is not supported and not validated on T140, we can not guarantee that it will work. "

https://dell.to/3CywbTE

Once again, Dell has not tested nor verified on 32G so there's no guarantee there.

Respectfully,
