memory upgrade problem of Dell 780DT

 I have ordered and bought two Kingston ram modules 2x4Gb in order to to upgrade my Dell780 DT.

The Ram Type is KVR13N9S8K2/8 (8GB PC3-10600 CL9 240pin kit).

According to Dell's document http://i.dell.com/sites/content/business/solutions/engineering-docs/en/Documents/optiplex-780-tech-g... (Page9) this memory kit should work on my system (after upgrading BIOS to A15 also) but unfortunately DID NOT.

I have the lights 1 & 3  litted with a buzzing sound without booting.

Reading a numerous posts i saw that there are many posts concerning memory incompatibility of Dell780.

Can you find me any solution about my problem?

Why at Dell's guidebook page 9 you report that this machine can operate with 1333Mhz memory types?

I contacted  the memory seller and can't accept any return of the memories i purchased, since they are not sealed anymore.

Do you have any plans to update the  BIOS to a compatible memory upgrade version if this could be  a solution, otherwise to look for selling my memory kit as used and buy another.

Thanks in advance.

RE: memory upgrade problem of Dell 780DT

The Kingston Ram is too slow.

It also depends on the form factor of the Optiplex 780.

The minitower Optiplex 780 accepts 4GB RAM modules as indicated by crucial.com, but the ultrasmall form factor Optiplex 780 only accepts 2GB modules, again according to crucial.com.
