Which Dells have UEFI
Is there a list of which Dells have UEFI? This is important for matching newer aftermarket video cards to older computers. I know the Ottiplex 780 was UEFI, but the 760 and older are a mystery. Right now I need to know about the Optiplex 360. But since I answer questions about Dells at Tomshardware Forum I could use a resource for this. It doesn't help that GPU sellers don't always provide this information about the GPUs they sell.

Zotac Geforce GTX 1050TI MINI cards and higher work in older BIOS Dells including Dimension E520 and Optiplex 755 AMD cards in the R series however do not seem to support DOS VESA Video mode 103 and therefore do not work in older dells. Earlier Legacy
Radeon HD 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000 series works fine. UEFI bios is NOT REQUIRED. CSM DOS/XP/MBR bios compatability of the Video card aka VESA 103 mode is required.
So Ancient DELL $6 cpus can run $160 GTX 1050TI Mini Pascal video cards.

Sapphire Support for Radeon R series on the otherhand is not happening.
The machines that have non working issues with GTX 1050/1060/1070/1080 are PCI-E 1.0 systems like the Precision 490 and 690.
These do not work at all with PCI-E 2.0 and 3.0 Video cards.

William P,
Unfortunately, there is no list of all the computers that have UEFI. The Optiplex 360 does not have the UEFI. It is from 2008

Perhaps it would be easier to make alist of those that don't have UEFI. LGA775 computers would be a good place to start. thet's when the switch occured. It owuldn't need to be updated either.

I wonder if all The LGA775 65nm computers can be assumed to be Legacy BIOS? That seems like a safe assumption. Optiplex 745, Dim. E520,510, Dim 9200, XPS410 etc>
Then let's take the DDR3 computers like the Optiplex 780, which is UEFI. Is that a safe assumption also?
That leaves a few 45nm DDR2 machines in the middle Opti 755, 760, T3400,T5400,T7400
It might be too convenient but maybe DDR3 and UEFI happened together?

I marked this unanswered to continue the UEFI discussion. The Optiplex 360 answer was very helpful.

Hey William P
The DDR3 memory and the UEFI Bios did come around close to the same time. Also, you are correct in your assumptions about the Opti 780 having a UEFI BIOS. and the ones with the Legacy bios too.

UEFI came out in 2011 and UEFI systems with Secure Boot came out in 2012.
The OptiPlex 360 (September 2008) and OptiPlex 760 (October 2008) have a Legacy only BIOS.
The OptiPlex 380 (December 2009) and OptiPlex 780 (September 2009) have a Legacy only BIOS.
The OptiPlex 390 (May 2011) and OptiPlex 790 (April 2011) have a UEFI BIOS but without Secure Boot.
The OptiPlex 3010 (August 2012) and OptiPlex 7010 (June 2012) have a UEFI BIOS but the UEFI BIOS must be updated to the latest version for Secure Boot.
Some more details are available here (the SMBIOS version can be used to determine if the BIOS is UEFI or Legacy):

DDR3 came well before UEFI 2.3.1 with systems from 2009 LGA1366. UEFI Class 2.3.1 in 2012(Secure Boot) is windows 8 and 10
Dell Studio XPS 435T / 9000 uses DDR3 and DOES NOT HAVE UEFI or Secure Boot. 6 slots 24 gigs max.

ACPI is used during Operation and UEFI is used mostly at boot.
CSM is Compatibility Support Module. Aka WINDOWS 7

Thank you all for replying to this. While it hasn't produced a concise list of what does and doesn't have UEFI, it has given some useful guidleines that didn't exist before. And the Radeon issues I was aware of but thanks for adding that so others that see this will know that exists also. I will mark this answered now.

UEFI is not an all inclusive always forever all models all years all features all windows. ALL MODELS from 2009 and earlier DO NOT HAVE UEFI. 2010 and 2011 is a grey Area with CLASS 1 UEFI 2012 to 2013 is UEFI Class 2.3.1 WHICH CLASS UEFI? There are systems with Class 1 that go back to 2010. After 2012 Windows 8 Secure Boot UEFI Class 2.3.1 was the norm. There are also Many Model Series AKA VOSTRO, DIMENSION, INSPIRON, PRECISION, OPTIPLEX etc.

You have given no reason WHY you need this information but its not hidden.

The reason is that some video cards require UEFI to run. It varies from one card mfg. to another with the same GPU.
I go to Userbenchmark,com (not much of a benchmark) to see which cards have actually run on which systems.
