Kingston Value Ram --- information on chips

[Afrd2shtstrngerS]

OK then, let?s give a shot...

Right now in my hand I have 2x256 MB PC3200 CL3 184-Pin DIMM KVR400/256R Kingston Value Rams. My questions are:

1) Which chips are used on these memory modules? (such as TCDD, Infineon, Hynix...)

2) I find that one module has "Kingston" label on the chips. Are these just re-labeled from another manufacturer like Samsung, or really manufactured by Kingston. In either case, I need some details or specifications...

And here some clues that I find after my research and a phone call to Kingston:

1. MODULE:
KVR400/256R 740617076530 2.6V
Assembled in USA
Part number is:
99C5192-011.A00
1626522-0721467
Chips are labeled as "Kingston" (however no finding on Kingston chips in google). On top of the chips here is what I can decipher:
"Kingston
N422024W1C
0422NO1
D3208DX1T-5U"

2. MODULE
KVR400/256R 740617076530 2.6V
Assembled in Taiwan X01
Part number is:
99R0006-001.A00
P742261-0280573
Nothing is written on chips except:
32Mx8 DDR400
One more note: Chips on this module are almost half the size of the chips in Module 1, AND this one has two circular holes in the middle of the module.

why?

 

[Afrd2shtstrngerS]

why not?

that question, and especially this answer was worth of 100 points when I was in college

Lets just say curiosity and enthusiasm, and kinda hobby kinda obsession after some point...

If you can't see what you are looking for immediately, then contact Kingston. They might tell you what you want.
Tell them it is for a school project.

Otherwise,

Run every series of numbers through google.

I have the same DIMMs, in fact. Mine are labeled "Kingston" on the chips themselves, and the label says "Assembled in USA", and some of the other ones that I've seen (newer production?) just have "32Mx8" or whatnot on the chips, and say "Assembled in China" on the labels. I used to see some older production boxes with Samsung chips, and some with Hynix I think too. (Hynix = decent overclocker.)

I really don't know who makes the "Kingston" chips, but from what I understand, Nanya used to be Kingston's number-one OEM chip supplier, so it's very likely that they are Nanya DRAMs, IMO.

Run the numbers though, and tell us what you find out. I'm curious too who made them.

Here is the blanket answer that for sure I am not satisfied with...


Dear Onur,

We use many different DRAM manufacturers for our memory (including our own
chips which are made by us). These parts may be made with one of any number
of DRAM chips.

You should set the memory timings to auto. It is not recommended you
manually set any timings for this part number.

The differences in the modules are differences in design on the circuit
boards used. These boards will be different depending on what components
are used. But all the modules are built and tested to the same standards
and specifications.

Well, hmm. Why exactly do you "need" the mfg's specs? Are the modules not working according to Kingston's data-sheets for that part number? They are only CAS3 modules, after all, but if they don't even work at stock specs, RMA them. Otherwise, use them and be happy, I guess. Mine work fine.

If you want modules with specific chips on them, then you should visually inspect them before purchasing. To their credit, most of the Kingston boxes at least do have a window on them so you can see the chips.
