[SOLVED] Dell T7910 and Windows 11 -- Will a Dell T7910 run Windows 11?

[BMoshier]

Hello,

I have a Dell T7910 with DUAL processor (3.2Ghz and 6 cores each) with 128GB RAM. Microsoft Health Check says it can't run Windows 11 because its 3.2GHz processor with 12 cores isn't good enough. Yet, health check says it only need 1GHz and 2 cores. Isn't 3.2Ghz and 12 cores more than 1GHz and 2 cores?

Microsoft is very inconsiderate given I just bought this T7910 and have yet to pay it off. Windows 10 won't be around past 2025. I really don't want my workstation to become a hacker's drone.

Thank you.

did you run test again today as its meant to be more clear as to why you fail.
might be something else

here are the cpu that should work with it - https://forums.tomshardware.com/threads/win-11-compatible-cpu.3709982/

expect the other people you can ask is dell

... I have a Dell T7910 ...

Thank you.

Hi,
Do not fear, I just got a T7910 as well and was also worried about the TPM issues for Win11. T7910s do have TPM chips and firstly you need to check if it's enabled in BIOS (under Security) otherwise the Health Check will probably fail (haven't tried it myself).

My TPM version was on v1.2 but I understand v2.0 is preferable for Windows 11. You may already have v2.0 (depending on when your system was originally made/supplied) but luckily, if you have v1.2 it can be flashed to v2.0 in a relaively painless way though the two sets of vaguely complicated instructions I found seemed to differ slightly and one outdated Dell link goes to an old update file that suggests the update is unavailable for T7910s.

NB, you need to have Bitlocker disabled (if you use it) as it uses TPM, and I guess if you have any other stuff linked with TPM that could be an issue - For me, I am just setting up my new computer and Win10 install so I had no issues.

To get hold of the TPM update, the best thing to do is enter your 7910s Service Tag at the Dell site (or download SupportAssist) and once Delll have identified your Dell, under "Drivers" search for TPM , then select and download the v2.0 exe utility (not the other two for v1.2 that I saw). My downloaded version was v1.3.2.8 A02.

Read the update instructions under the details of the download but also check the following reference for Dell's further advice (but don't download the update via that outdated link where it also suggest the T7910 is NOT supported!):
https://www.dell.com/support/kbdoc/...hange-between-1-2-or-2-0-because-tpm-is-owned

Essentially, I didn't need to create boot USBs or anything complicated - after following the instructions to disable "TpmAutoProvisioning" and the note in part 4 of the link above ["In the search box, type the command: tpm.msc then press the Enter key to open the TPM management console. (See figure 3.)"], and following the reboot process etc, I then just double clicked the downloaded exe and everything happened automagically. I watched it reboot again and saw the firmware update process happen on screen in a matter of seconds then the system rebooted again.

I did momentarily have a sinking feeling when upon rebooting I got an error message saying something about a TPM enable error, but I just hit F1 (Retry) and Windows rebooted whereupon I followed the advice in the notes to "Enable-TpmAutoProvisioning".

I rebooted again after all that and checked my BIOS and indeed it now says TPM v2.0.

I think TPM would be the only issue for Win11 for us (the version or not enabled), everything else should be fine.

Hope that helps you and anyone else looking, hope I didn't miss anything.

Hello,

I got my T7910 upgrades successfully to TPM 2.0 and its verified on TPM 2.0.

The Microsoft PC Health program still says the T7910 can't run Windows 11.

I downloaded the GitHub program: WhyNotWin11. The results are all Green, except for CPU Compatibility, which is Yellow. The message is: "Not Currently Listed as Compatible."

It checks the following areas (my results):

Architecture (64 bit) Green,
Boot Method (UEFI) Green,
CPU Compatibility (see above) Yellow,
CPU Core Count (16 cores, 32 threads) Green,
CPU Frequency (3200 MHz) Green,
DirectX + WDDM2 (DirectX 12 & WDDM 2) Green,
Disk Partition Type (GPT Detected) Green,
RAM installed (128GB) Green,
Secure Boot (Supported) Green,
Storage Available (857 GB C: 6 Drive(s) Meets Requirements) Green,
TPM Version (TPM 2 Detected) Green.


Sigh: I hope (to me the T7910 is a recent system) doesn't turn into a Russian bot in 2026 and later.

I still find use for my Dell 390 computers doing stuff like supporting drives or DNS or mail, etc.

That sux, hope they extend compatibility in next few months.

From what I can find, your Xeon processors came out a little bit earlier than 6th gen i3/i5/i7, so no, it likely won't run Windows 11 if the cut off is 8th gen. It has nothing to do with cores and threads, it has to do with age.

What Joseph_138 said. CPU below. Now you can download the ISO and then install it. You just can't update through windows update.

Also I would wait. I just installed on an Optiplex 790 i5-2400. It has TPM 1.2 but no secure boot so had to use the reg hack to bypass that. Don't know if that reg hack will work in the final release or not. The reg hacks only work for lack of TPM and lack of Secure Boot. The CPU doesn't really get checked except through windows upgrade.

I'm try install 10 on this Optiplex, then download the ISO and upgrade directly from there and see if I can get past it or not.
