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.
http://m.ebay.com/itm/272240256121. Ah, another failure!
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...
+1 for 12800
