XPS 8700, possible to add a TPM?

I have an XPS 8700 and it is running well with Windows 10 but I don't think it has a TPM chip. TPM 2.0 is going to be required by Windows 11.

Is it possible to add a TPM chip to an XPS 8700?

Thanks

@Paulrp1   that is incorrect about TPM

The XPS 8700 does not have 1.2 TPM or TPM hardware.

It has INTEL PTT in bios. 

Some Dell systems do not ship with a TPM(Trusted Platform Module) module, and instead, use PTT (Platform Trust Technology). PTT is a lower-cost solution that supports the same functions of the TPM 2.0

The Trusted Platform Module should show under Security devices in Device Manager.

8700 has PTT and UEFI CLASS 2.3.1 secure boot ability.

There is No option for TPM in BIOS Setting, which is under security, only INTEL PTT

There should be a setting for this in F2 BiOS.

Intel PTT is basically the firmware (bios) alternative to a the hardware based TPM. Intel PTT works on pretty much every processor/chipset since 4th Gen Core (Haswell) processors were introduced and it even supports Bitlocker. This is because Intel PTT supports all Microsoft requirements for firmware Trusted Platform Module (fTPM) 2.0

  • Some Latitude, XPS, and Inspiron systems ship with the Intel PTT

 

TPM Type Supported TPM Modes New Firmware Available Supported Platforms
OLDER TPMs (Multi-Vendor) 1.2 No All systems up to the Skylake processor generation
Nuvoton 650 (aka 65x) 1.2, 2.0 Yes (1.3.2.8 for 2.0 Mode and 5.81.2.1 for 1.2 Mode) Latitude xx70/xx80, Precision xx10/xx20, OptiPlex xx40/xx50, Precision Txx10/Txx20
Nuvoton 750 (aka 75x) 2.0 Yes (7.2.0.2) Latitude xx90, Precision xx30, OptiPlex xx60, Precision Txx30
Intel PTT 2.0 No (Part of BIOS) Dell Consumer system models and some Latitude/XPS tablets
STMicro 2.0 No (Current is 74.8.17568.5511) Latitude xx00 (generation 10)

The wise ones have given me this knowledge. It seems TPM's are not a CPU issue but are related to the motherboard and it's chipset. Apparently a TPM has to be soldered to the motherboard, look for a socket (aka header) for a TPM on your motherboard. It seems a lot of home builders didn't add a TPM but they probably have the socket. My m/board doesn't have the socket header. Expect a worldwide shortage of TPM's anytime soon.

I was hoping for a USB TPM but it seems that can't be done.

@Vic384  This requirement is a pain. I'll be keeping an eye on the situation as we get closer to the rollout and see if MS drop this requirement

Tap the F2 key when the Dell logo appears to enter the BIOS Expand the " Security " section, click " PTT Security ", and deselect Intel Platform Trust Technology NOTE: If PTT is greyed out as well, re-enable PTT by disabling Intel Trusted Execution under Virtualization Support. Click Apply and Exit to reboot

Its under security. tab PTT Security may require latest bios. cant jump from A00 to A14 in a single step

WONT be anything that says TPM in F2 bios.

Also wont be available in embargo'd countries.

@gartaudSame here, the A14 update didn't give me any new menu items.

My PC still performs well, it is not at all sluggish (SSD & 32GB RAM).

I don't really want to have to try and get a new PC during the current chip shortage.

June 25th, 2021 07:00

@Mary GThe only problem for me is the TPM.

My PC actually runs well, it does not struggle at all, I maxed out the RAM at 32GB so that helps I guess.

Surprising for a 7 year old box I know but I don't want to have to try and get a new PC during the current chip shortage.

June 25th, 2021 07:00

I have Bios A13 and there is no PTT (or TPM) option.

I wasn't clear in my original post, mine is a 4th Gen Core i7 (i7-4770) from 2014.

My query is really whether it will be possible to add TPM 2.0 as a module or something?

I will try the upgrade to A14 (once I have verified it is legit)

If you are wondering about running windows 11-- it is not possible on the 8 yr old model. Only processors from last couple of years can run it. My 8700 couldn't even run the test app. I knew that but wanted to see the list of complaints. It would not even run.

I have BIOS A14 and I do not see any option to enable Intel PTT in the BIOS.

I have upgraded to A14 a long time ago and A14 works fine for me but the settings in the BIOS are the same as what you posted for A13 (also using a 4th gen Intel CPU)

@Chainsaw Dude I have read that end of support for Windows 10 will be 2025, so hopefully, the current chip shortage will be over long before that happens. Windows 11 is not even available yet and your current PC is running just fine so there is no need to worry. Around 20% of PCs are still running Windows 7 even though support ended on 1/14/2020.

@Chainsaw Dude I will also be watching the TPM 2.0 issue, but another issue is the processor requirement, for a PC with an Intel processor it has to be 8th Generation or more recent, and if the TPM issue doesn't stop your upgrade to Windows 11 the 8th Gen processor issue may.

@Chainsaw Dude You may be OK if look at the document you posted but not if you look at this: https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-intel-processors

This article: https://www.onmsft.com/editorial/microsofts-restrictive-windows-11-requirements-may-leave-lots-of-not-so-old-pcs-on-the-sidelines

discusses hard floor and soft floor requirements for Windows 11. I think that if Microsoft makes those soft floor requirements actual minimum requirements they are not going to be happy with the number of upgrades from Windows 10. Like the upgrades to Windows 7, 8.1, and 10, Microsoft had to adjust the minimum requirements because of customer complaints that their systems would not be supported.
