Help! Need to find out mem type??

[wmabern]

Hi folks,
I've got some old 72 pin mem chips (lots of em!) of different types and am trying to fill up an old Pentium 233 with as much as I can to keep it serviceable.

Right now it has 128 meg in it. I have 2 more slots open (another bank) so I need to find out what I have and if I can match the chip types, speed, etc in the last bank to fill her up.
I hate that it is not clearer on the chips EXACTLY what they are!!!! Anyway, can someone help me with codes on the chips? Or point me in the right direction to find out?

1 of the chip types has this on the modules:
LGS
GM71C17400bj6
9623 KOREA
There are 8 modules on a single side and under each module it has: U1, U2, U3 etc.....

The next chip type has this on the modules:
9332 K USA
MT4C001JDJ
-7
There are 8 of the modules also on a single side. The chip itself has 20VD on 1 end and GT-7243 on the other end. Any ideas?

Thanks for any help.

Well. I have found out that the MT is Micron Memory, that the 9332 means the 32nd week of 1993 and -7 means 70 nano- sec ram.

As for the other chip 9623 means the 23rd week of 96. I have no idea about the LGS or any of the other numbers.

I think I'm just gonna put 2 of the 1996 chips in and see what happens. The reason I haven't just done this to begin with is that I have to pull the whole freaking board out to get to this bank of memory and that means pretty much dis-assembling the whole thing... So I just wanted to go with what I had that was best the 1st time. I'm sure the 1996 chips are of a higher rate than the 1993. Heck, I barely remember 1993 or '96 for that matter much less what kind of chips I was buying then!
I have a sneaking feeling however that the '96 chips are 16 meg chips... Who knows? I don't, But I'll find out! Later.

Yep, those 1996 chips were 16 megs. Popped in 2 of those in the last bank. I now have 160 megs in that old thing. I think that will keep it churning a little better for a bit. I use it as another terminal/storage device networked with my main system. I have em connected through a hub and linked to Road Runner. The main box is a t-bird 1.2 w/512 of 133 sdram. That's a big leap up from 160 megs running on a 233 pentium! Best to all.

Generally speaking modules with 8 chips are usually 4MB or 16MB. 16-chip modules are usually 8MB or 32MB. Put a matching pair in and see what it says!
