Is my ECC-RAM broken?

[DahGamingNinja]

I own a Dell Precision T1600. I recently purchased 16gb of used ECC RAM for my precision, seeing that it supported up to 16gb of ECC RAM. It was 30$ USD so, a pretty good deal.

(Link to T1600 specs)

(Link to original ECC RAM listing)

I received the RAM today and plugged them both into my mother board. The mother board beeped twice then beeped in sets of three. It did not turn off but nothing was displayed on my monitor (no start-up, no bios, etc.). I then plugged in my original RAM along with the two new ones. It turned on and worked as expected. I then ran a system & components scan to check if everything (including the new RAM) was working as it should be. Everything checked off as 100%. Entering my system settings I found that only recognized 8gb of installed memory. My motherboard supports ECC RAM and the components check resulted in no error. So my question is, what the heck is wrong with my setup?! Is my RAM broken? Is my motherboard lying to me and actually not compatible? Please inform me.

Thanks,

It actually lists 4 DIMMs up to 8GB Non-ECC or 16GB ECC. Given that we should deduce that it supports up to 4GB ECC modules, and it supports up to 4 of them at once to achieve 16GB. Installing a pair of 8GB ECC modules is probably just memory that it doesn't recognize because the density is too high. You would need a 4x4GB ECC set not a 2x8GB ECC set.

Are you sure, this is a Dell Precision and implying that they only support 4x4gb of ECC RAM sounds a bit too retarded for a workstation. Is there anyway to force it to recognize the RAM since it supports it?

Doesn't support 8GB sticks, this is an early 1155
