4 gold finger ram (see 2)
3 gold finger cards (barely)
2 gold finger ram (see below)
1 peripheral (smart to just trim these to fingers)

4 has me confused a bit but 2 definitely looks like system powered vRAM drive boards. 4 has a SLC ram chip som MLCs, a controller? . I’m going to go with ram on both.
For general purpose note this grade is for this set of pictures alone.

its got a sandisk on it but micron too...i think its more storage yeah but not ram. looks like a plug top left corner too. i am not a computer engineer

edit

"HP DL 360 G3 64MB Raid Cache Module "

raid cache, so would that be more ram-like.

I come across stuff like this every now and then. I always preferred to just make my own at a fraction of the cost (ram + 2 8-gage wires + 9volt + resistor) but commercially available units exist.
It’s ram with a power source. Using ram as a drive with a system PSU trickle vamp to hold data on shutdown.
Coming across this stuff isn’t all that common. These boards (in general) cost a fortune new and nobody will pay a penny for them used. Not worth the risk as they’re known to die out.

In printers you’ll find it as semi-volatile storage for fonts or layout translators. In the early days we used ram on breadboard with batteries to create super fast drives. If you dig you can find ‘ram-drives’, or the board kits to build them, on amazon.
