So, I took the (modest) leap and purchased a Dell p/n: 061p37. Maybe(?) the apparent incorrect performance spec is Dell's, but, then, the p/n on the spec sheet you linked to IS different. OTOH, this card I have is definitely a Nvidia NVS 510 2GB Video Graphics Card. While the RAM is 2 GB DDR3 (confirming Dell's hardware spec for, evidently, both p/n's), installed, the card (running Port 1 to my 4k / 60 Hz TV / monitor, no other outputs connected) will only crank out 4k @ 30 Hz. All other items in the "chain" (like the cable) have good reviews regarding bandwidth and should handle 60 Hz, so, I'm mildly disappointed. (I was hoping that Dell spec was right!) However, for my primary uses, the 30 Hz is sufficient.

Best guess is that 4k @ 30 Hz is the most the 2 GB of DDR3 can get ya' in any similar architecture card.

I did stumble into Nvidia specs indicating the "consumer" version, NVS 640, has been made with both DDR3 and (later obviously) with GDDR5, with the "GDDR5" tacked onto the end of the model number. So if 60 Hz becomes useful, maybe I'll look for one of those... (I can also drop to 2k @ 60 Hz if not working with small text or speadsheets.)

Interesting.

As another FReeper pointed out, unless it’s your job, it’s almost impossible to stay abreast of all the tech specs.

Even though IT is part of my own, I only delve into specs when it’s pertinent to either troubleshooting or procurement pursuant to a goal.

Your experience is just another level of 4k troubles I’ve read about anecdotally, my own video problems knowingly rooted in a laptop with now-known wholly inadequate video ability (a hand-me-down).

It was a point of humor when I recently observed an IT dept dealing with vexing hardware and video issues pertaining to an IP based security camera system.

Ironically, it all comes back to KISS.
