The reason I update these to Bios A11 has several reasons.
Fixes
- Fixed SMBIOS memory reporting for systems with 2 DIMM slots.Enhancements
- Added support for Cedar Mill/Presler D0 step processors made in 2006.
- Enhanced internal hard drive diagnostics tests reporting.
- Enhanced hard drive password functionality.
- Enhanced support for mismatched memory.
- Enhanced module bay functionality.
- Enhanced OROM shadowing into BIOS.
- Enhanced PCIE read completion boundary function.The GX620 is a very special machine because it runs everything from MSDOS all the way thru Windows 10. It also supports all Drive types including both SATA and IDE on the same box. This makes it a wonderful data recovery unit.
1. Pentium D 900 series is required for windows 8.1 or 10.
2. Windows 10 will be 64 bit only from now on.
3. Video Cards like the GT1030 are now required to run some games.
Newer R Series Radeon cards and Newer RTX Nvidia cards will never work in these systems because UEFI bios is required for those.
Every other Card up to GTX 1080 TI will work but you may need to get bigger power supply and you must use X16 slot extender because full length cards do not fit into the GX620 case. There are no issues with XPS400 which is the other model of the same vintage.

That is a 13 year old system and why risk fate. There have only been 2 BIOS updates according to the support page and the newest is labeled optional. I never suggest a BIOS update just to have a newer update. If you are having a problem that the update addresses that is another matter. But for a system as old as you have and assuming it is working as well as a 13 year old system can work, I would leave it alone.

y2e2, what problems occur that you need to update the bios?
I think @speedstep may have one of these old machines or a similar model, and will probably see your post early tomorrow morning. Until then, don't try to do any update.
Some dell bios updates have been known to crater the motherboard. Dell will only help if a dell support person directed you personally to perform the operation.

Hello!
I have a question about the BIOS GX620A10 date 04/06/2020
Is this the BIOS update from 27/10/2006?
Should I have a BIOS A10 from 2006, should I update? what is the difference between these two BIOS from the description can be inferred that they are identical, but the difference in the size of the EXE files.
Thank you.2454

GX620 requires XP or MSDOS floppy to update bios.
A11 is the last version.
CANNOT BE RUN FROM DOS WINDOW INSIDE WIN7
Must be run as administrator.
ANTIVIRUS SOFTWARE WILL BRICK THE MACHINE IF ITS INSTALLED AND YOU TRY TO UPDATE BIOS. iT WILL CRASH JUST AFTER IT ERASES THE BIOS AND BE DEAD AFTERWARDS. 1.44 MSDOS FLOPPY is the safest way to update this specific bios.
Main reason to install A11 is updated memory timing as well as supporting pentium D 900 series and windows 10. Pentium D 915 processor is very cheap.
