Hi my pc uses pc100 ram, i have 2 slots , that occupy 2 sticks of 64mb
totaling 128mb, recently i recieved a 128 mb of ram stick the only problem
its pc133, the 1st thing i tried is taking out all of the ram i have in my
pc and install only the new pc133 stick, it did not work, second thing i did
is leave on of the 64mb of ram pc100 in the slot , and in the remaining
slot insert the pc133 ram, did not recognize the pc133, and then i tried a
combination of swiching ram positions. Can some one tell me if this is even
possible, or should i just sell this pc133 of ram on ebay, thanks in
advance.

Well if you do sell if on ebay you will have to sell it as untested and
I doubt you will find a buyer.

I assume the ram woud have worked, but I am no expert on ram.
In which case you woul have to sell (or rather not sell) it as faulty!!
 
133 should work, if it was the wrong density, it
would only be partially recognized. The symptoms
you quote are that it is defective.

I think that RAM needs to be inserted in matched pairs. Both slots need to
be the same.
 
Ok, im planning on buying a stick of pc100 128mb from a friend of mine, the
stick has been tested and works fine on his PC, will it work ok along a
stick of pc100 64mb and that way i would have 192mb of ram ?, Thanks in
advance.

I highly doubt that is the case. Aside from RAMBUS memory, you haven't
needed to fill matching banks since EDO RAM.

Not "pc100/pc133" RAM. Take a refresher or refrain from advice on things you
don't have knowledge of.

It should do, although HP's can be fussy. If he's a friend he'll take it
back if it doesn't work.

Let me guess, the new PC-133 stick has 4 chips on it, and your existing ones
have 8 chips? If so, it's a common problem I have run into in both PC-100
and PC-133 SDRAM modules lately, and older systems, especially those with
the old 440BX chipset, and the 810/815 chipsets. Your system may well
support PC-100 or PC-133 modules in 128MB capacities, but some older
motherboard chipsets do not support the newer 256Mbit density chips commonly
being used today. On a 128MB module that uses 4 256Mbit chips, each chip is
32MB for a total of 128MB. The older 128MB modules with 128Mbit densities
had 16MB per chip, and used 8 chips for a total of 128MB. The best advice I
can give you is to go to Crucial.com and plug your model# into their
configuration matrix, and let them select the proper type of module(s) for
your system, then purchase it. More than likely you will see a warning
message that your system takes a specific type of SDRAM module. Looking up
the specs on your machine reveals that it does indeed use an Intel 810
chipset, and thus needs modules with 128Mbit chip density. If you don't
order from crucial, look for modules with 8 chips on them.

How many chips are on this 128MB DIMM, and what are the part numbers on the
chips and DIMM?

Does this 128MB DIMM only have four chips? If so, they are 16Mx16(256Mbit)
chips. This system will not support 128MB DIMMs with only four chips.

This system uses an Intel 810 chipset. It supports memory chip densities up to
128Mbit. It will support 256MB DIMMs that use sixteen 16Mx8(128Mbit) chips. It
will support 128MB DIMMs with either eight 16Mx8 chips, or sixteen 8Mx8(64Mbit)
chips.

Maybe your motherboard doesn't accept PC133? The RAM may work fine, but your
motherboard doesn't support it.

Thats what it sounds like to me.

And with *some* RAMBUS/RDRAM motherboards, filling both slots may entail a
RIMM in the first slot and a (non-matching) Continuity-RIMM (CRIMM) in the
second - ie only one stick of memory is essential and the CRIMM is basically
a blanking module to terminate the memory bus. An example is the Asus P3C-E.
