Memory Compatibility for Optiplex 780
HI,
I'm having a problem trying to upgrade the memory for my Optiplex 780. Short version: this Desktop only have compatibility with "DELL" Kingston memory and other "NO DELL" Kingston memory with the same exact specifications don't work. I have the last A15 Bios and I've tried both memory models in all combinations but with the new memory inserted (and no, it's not a defective memory) I get green 3 & 4 lights with no boot just connecting the power.
Question: Is there a compatibility solution? Can we have a new A16 Bios to fix this?
THANK YOU!
Additional information:
- The memory is 4GB DD3 1333 MHz PC3-10600 1.5v CL9 Non ECC 240 pin. The manual "optiplex-780-tech-guide.pdf" says it's ok, and it's the same specification that a working "DELL" memory.
- Kingston lists that both models KTD-XPS730A/4G (1066 Mhz) and KTD-XPS730B/4G (1333 Mhz) are discontinued (see link below) and it's hard to find in my country any Kingston KTD model, so that's why I need to use a similar memory.
- This are the specs of the working "DELL" memory:

- This are the specs of the "NO DELL" non working memory:

Have you tried using Crucial UK?
The OptiPlex 780 has several different versions:
Mini Tower
Desktop Computer
Small Form Factor
Ultra Small Form Factor [USFF]
Here are the Dell OptiPlex 780 Mini Tower compatible upgrades:

If you have a different OptiPlex version, other that the OptiPlex 780 Mini Tower, compatible memory for them can be found by, clicking 'Store' at the top of this page.

Thanks for your answer, shesagordie!
The link you gave me (for the Small Form Factor version) lists different memory models I will try to find in my country. Besides, I see that these are all "taller" than the Kingston I bought. I don't know if this is the problem.
They are listed as "Form Factor: UDIMM" but I don't know if that is related to the "height", and if this can cause compatibility problems. I post below a comparison between a working and a non-working sticks. I will try to find some of these models and I'll post again.
Thanks!
