Help me identify this RAM

[brikis98]

I found some RAM packaged in an anti-static bag at work and I can't figure out all of its specs. Here's the info I can find:

Sticker on the stick of RAM itself:
* Viking logo
* PC2100 Compliant
* 144297324
* VI4CR327228DTH01
* PC2100R-25330-Z

Sticker on the anti-static bag
* Various information about Viking components
* 1 Per Ser: 144297324
* 14284619 VI4CR327228DTH01
* 4B02 SAMSUNG 1B07

From this, I've been able to figure out the obvious: this is PC2100 RAM made by Viking. I'm also guessing it's server RAM (ECC/Registered) as most of the RAM at work is, but I'm not sure. Given I have no computer I can put it into to test it, how can I figure out:

* The capacity
* The timings
* If it's ECC and/or registered

Did a Quick google and found
Link
Which says that PC2100R-25330-Z is a 256mb pc2100 ddr registered ecc ram

thx for the help.. unfortunately, that link also shows PC2100R-25330-Z under 512mb and 1gb of pc2100 ddr registered/ECC... assuming the server RAM is correct (which it prob is) how can i be sure what the capacity actually is?

If you can plug it in to a system, try running Everest Home Edition (a free program) to identify it.

i don't have any systems that support pc2100 server RAM, so that's not an option...

It seems to have a CAS latency of 2, but only if the PC2100R-25330-Z chips all have the same value. The stick in the link is a 1GB model. Both Micron and Corsair manufactured memory from PC2100R-25330-Z chips, but I can't seem to find much info on them.

Corsair: CM74SD1024RLP-2100/S 023713 PC2100R-25330-Z (1GB PC2100 ECC)
Micron: MT36VDDT12872G-265B2 PC2100R-25330-Z BZABTFE002 200252 (1GB PC2100 ECC)

Good luck.

thx for the link... the stick of RAM i have looks similar to the one in that picture, but not quite. For one, the picture has a Micron (i think) sticker, whereas mine is Viking (although the actual parts are prob. made by the same company).

more importantly though, both sticks appear to be single sided and have the same number/arrangement of the black "chips" along the module (4 vertical ones under the sticker, 5 vertical ones to the right of it). however the horizontal black chips in between the vertical ones are different in the picture than in my stick of RAM... so, i'm still uncertain...

is there any way to tell the capacity based on the number of these black chips on a single sided stick of RAM? or any other ideas?

You can tell the capacity by knowing the width and depth of the chips on the stick of ram.
Post the numbers on the chip or google them to find out.

how do i tell the depth and width of the chips?

i can read on each chip:

Samsung 504
K4H560838F TCB3
H56 B CFL281DBC

There are 8 of these chips and the RAM is single sided.

Sounds like it may not have ECC or Full Buffering if it doesn't have a 9th chip.

Question
How do I identify what type of memory module I have?
Answer
If you have a Viking Components' memory module, there should be a white bar code sticker on the module with a number under the bar code. This number may start with an "E" if manufactured in our European facility. With that number, our technical staff can tell you exactly what memory module you have. If that sticker is no longer on the module, we may be able to assist you with other numbers on the module, providing that the Viking Logo or Viking Components is silk-screened on the printed circuit board of the module. A memory module is composed of a PCB (Printed Circuit Board) with rectangular memory chips, or IC's soldered on it, and various resistors and control chips. There should be a 7-digit number starting with a '9' or a '0' silk-screened on the printed circuit board (9xxxxxx or 0xxxxxx). We would need this number. We would also need to know how many chips are mounted on the module, counting both sides of the module as the total, and the identifying number that is engraved on one of the memory chips. This would be a long number starting with one, two, or three letters, such as D, TC, KM, HYB, etc. This would allow us to tell you the size and type of memory that is used on the module. If it is a proprietary circuit board, we might be able to tell you which computer it is used in by the 7-digit printed circuit board (PCB) number. 72 pin SIMM's will also have four solder points labeled as PD0 through PD3 in one corner of the module. Resistors soldered on these points will determine the speed of the module. We would require this information to tell you the speed rating of the 72 pin SIMM. If there is not a white sticker and no Viking logo or Viking Components silk-screened on the module, we would not have the information needed to assist you as it is not a Viking Components' memory module. You can email this information to our technical support staff by clicking the "Ask a Question" tab on this page, sending an e-mail to techsupport@vikingsupport.com, or you can give us a call between the hours of 8:30AM and 4:30 PM Pacific Time, Monday through Friday, at 1-800-845-8777, with the module in hand.
