I know that I need either PC3-8500 1066mhz or PC3-12800 1600mhz ram will work.

I have already tried PC3-10600 which supposedly works after a bios update according to one source, and was recommended by one memory scanner. However, that failed.

I have & a set of GSkill Ripjaws recommended by the 'tech specialists' at Newegg that I had to RMA for a refund, and the Google Trusted Stores consumer protection intervened to knock off the 15% restock fee, otherwise would have eaten a $35 loss to beta test the set on my system. As it was, still lost over $17 for the 3 day shipping & return label for RAM combined.

If someone has a Dell Optiplex 780 sff and can crack it open for me to look inside or lives in western NC and has a stick of each, even if 256mb keychain-fob worthy, I would appreciate it.

It's the one that takes the low profile graphics cards! (Yes, I think there may actually be a difference, as that is the simplest explanation for confusion, also different size dells do use different motherboards and have differing memory limits!)

... Mostly right... Except for the ram... Which I already tried!

You see, 1066mhz is actually PC-8500, however they list PC3-10600... And it MIGHT actually be PC3-12800

Someone saId it does support 10600 after an update to bios A30... Which is not available for download. So... More wrong...


Help!

Nice Title Btw.

 

Here is the Manual for it which says it uses:

Type: DDR3 Synch DRAM Non-ECC Memory

 

Page 9/40

the DIMM capacities for each slot is 2GB so 8GB max for SFF Dell Optiplex.

"Optiperplexing" - hah!  :lmao:

 

According to a manual I f-nevermind. Viper_Security got it first. The manual seems a little confusing. It says DDR3 is the correct type, and then lists a bunch of DDR2 modules.
