I had a Dell Dimension 8200 computer (a full height tower CPU) that I bought new and owned for a number of years, then sold. I recently discovered two memory chips (or what I thought were memory chips) that as best I could recall, I removed when I upgraded the computer memory.
The OEM memory of the computer was 512MB PC800 RDRAM (2x256). I posted the a description of two memory chips on ebay, along with a picture of the them, and sold and shipped them. I just got an email from the buyer claiming this: "What you sent is not memory at all. They are blanking chips to be used when only one chip of a pair has memory chips on it. What was sent has O memory total ... ",
I did a search for "blanking chips", "blanking memory chips", "blank computer memory chips", and so on, and don't really find any information. I have had quite a few computers, and don't recall ever having any "blank chips" in any of them, though often there certainly were unused empty memory slots.
The picture is of the two "chips" in question. Can anyone advise me for sure, one way or the other, if these are real memory chips, or is my buyer correct and they are blank dummies? The buyer wants a refund because he claims they are worthless "blanking chips", which I am willing to do if he is correct, but I want to determine what they are before I proceed.
Thanks in advance for any assistance.

requesting Tech Ping ... thanx
You owe someone some money back. LOL!
prepare to be barraged by morons.
good luck!
si.
They look like ‘place holders’. What does the other side of the chips look like?
the 512k memory was installed on the motherboard (probably). the chops shown are nothing more than blank place holders that are removed when memory is added. I suspect the buyer is correct and a refund is in order. it’s an honest mistake.
I think that he means banking, or just bank, memory, which is meant to be used in pairs, and the system board has to support it. You can tell by the way the little notches on the connector edge line up on the main board.
The first clue should be that there are no little black things on them.
Sounds like a parity issue - how old is the box?
Sorry, I didn't take a pic of the back side of the chips, and I don't really recall.
These are “dummy chips”, unique to RDRAM (which isn’t used much anymore. The original Pentium 4 used them but then went to DDR Ram.
See the Wikipedia article ref: CRIMMs.
What you have are “memory spacers” like these:
Purchased new from Dell, August 2002
A RAMBUS Continuity-RIMM (CRIMM), also known as terminator or dummy.
Are the memory modules on opposite side? If I recall correctly, memory sticks that were 256 only had them on one side, as opposed to 512 which had blocks on both sides. Although I am not familiar with RDRAM, so I could be wrong.
You screwed the pooch. lol.
Those are not memory chips. They are rdram terminal/continuity chips.
