Identifying PC memory?!

[Capn Trips]

I figured this is as good a place as any to ask this non-remote, non-JP! question.

I have scavenged a few DIMMs from computers being replaced/upgraded and was aondering if anyone can help me to identify their specs. Information on the DIMMs is as follows:

(1) The easy one:
It's a DELL with eight chips, each chip has the following markings

0212 3-1
MT 48LC16M8A2
TG -75 B

with

XB3T

sideway across the chip.

What makes it easy is the Dell sticker on the DIMM that says

MT8LSDT1664AG-10EB1 PC100-222-620
MY KP0237153 200237C
128MB, SYNCH, 100 MHz, CL2

so how does all of the other info on the chips tell me that this is a 128MB DIMM (since my other ones do NOT have a convenient sticker to that effect)?

(2) The next one:
Eight chips, each with some kind of stylized "H" plus:

HY57V1298020
LTC-8
9928A KOREA

There is a sticker but it tells ME little:

409457 PRD
A3VB-CH05DQ
S-DRPC128HYTD

Can I presume this is a 128MB DIMM?

(3) Finally, a DIMM with 16 chips, each with:

LGS
GM72V66841CT7J
9908 AG7 KOREA

and a sticker:

GMM26416233CNT
G-7J 9091N
PC100-322-620

Any idea about the speed and capacity of this DIMM?

Thanks in advance.

Crucial Memory will tell you what you've got in your system and from this you can infer what you will need if you are planning to upgrade:

Register (free) with IC master and their site lets you type in a part number and does a search of over 50M parts:

Your Korean part looks like it is a lowly 8MB

[120240VAC60HZ]

Can you put them in a computer? If so that would make them easier to id as there are several system Identification tools out there. Such as CPU-Z, Everest, SIW (System Identification For Windows), and Belarc advisor. and also BIOS Should tell you the amount of ram in the system when the system posts

From looking at the serial # I think they each are 128 mb. The 1st and 3rd are micron, The second is a generic hyundai.

If you can understand the numbering on the IC, you can deduce the capacity of the entire module. I used to be good at that, back when we used 72 pin memory.

For the last one, GMM26416 is 16 MB, at 64 bits, which is 128MB .

..uhhhh, thanks a lot fellas, but reviving an 18-month old thread? I'm way past this question.

Thanks anyways.
