I'm trying to find the manufacturer of some 4GB DDR3 PC10600 registered ECC DIMM, but Internet searches for any of the markings on the label turn up nothing valid:
P/N: 34RS13JRMFJ0010 0016456
P/C: 34-04-00020-R
Desc: 4GB, 512Mx72, PC3-10600 9-9-9
It has Micron chips on it (but is definitely not a Micron or Crucial DIMM) and an Inph brand register chip.
The logo is a pyramid with horizontal stripes on one face:
Maybe here....Paul
This link seems to indicate 'exactly' that ram and the part number is 'Micron' - but the site's listing doesn't say Micron Tech or Micron Technology tho'.
But... Micron Technology doesn't have that logo and the micron website seems to say to me that all of their part numbers start with MT.
That is very confusing to me, and also, I've seen that pyramid before, but I can't remember where or what.

The module is major on third.
The link found seems correct, right down to the logo shown top left of the web page.

The module is Legacy Electronics branded. Legacy is a small company that *makes* memory modules. The web page in question isn't just reselling someone else's module. (One financials web page claims they have 50 employees, but that can't be right). The pyramid logo seems to be theirs. The chips on the module may be Micron chips, but the brand of the finished module is Legacy Electronics.
Just about anyone can make modules if they want. There is one company that sells PCB blanks for DIMMs, if you want to get into the business. You buy a soldering production line, plug PCB blanks and memory chips into one end, and DIMMs come out the other end. You come up with some kind of crazy testing scheme for the products (test them in desktop motherboards for example), put them in a blister pak and you're in the memory business. Your business fails, because margins are so thin.
You can see a movie of the dudes at Legacy, doing just that. Unzip and play in Windows Media Player (about 29MB). I got the movie, just for the sound track :-)
The reason a company like Legacy is around, is not because of that particular module. They are one of the companies that makes specialized memory modules. There are ways of mounting chips on top of one another, to make double capacity DIMMs and the like. For a lot of money, a company that wants to fill a server with memory, could buy some of those higher-than-normal capacity DIMMs. And that is what would keep a business like Legacy around. Making ordinary DIMMs would be pretty pointless, as the Chinese or Taiwanese would eat your lunch. Still, if you need to keep your production line running, you might fill part of the capacity with ordinary memory products, even if you weren't making money from it.

Ah, so. I get it now. Doh. I neglected the legacy pyramid.
Yes.
Gotcha.

Micron makes the memory chips... Legacy assembles the unit.
That's it! Thanks, Paul.
Funny, but I have an 8-year-old 256MB PC133 module from them, only there's no triangle logo on it. It's made with 16 wierdo 32Mb x 4 chips, not the usual 16Mb x 8 chips, so it's not fully recognized by many older motherboards. It was included with a $50 Black Friday Maxtor 80GB hard drive.
Your're welcome. Trick I use is to first search on the whole number. If you get few or no hits, delete the end digit one at a time until you a good return.....Paul
