Hi,

I own a Gateway GP6-233 computer with a PD440FX motherboard and 32MB of
Samsung memory.  The Samsung memory is identified as fully tested and
working with the machine (KMM5324104BK-6).  Its specs are as follows
(according to the Samsung part number decoder
http://www.usa.samsungsemi.com/buy/decoder/dramsimm.htm):

72pin DRAM SIMM 4Mx32 2K EDO 60ns Tin >7chips

I want to add another 128MB (2 64MB SIMMs) and found that the following
Samsung memory also works:

KMM53216004AK-6 (as shown in
http://www.intel.com.sv/design/motherbd/pd/pd_mem.htm)

72pin DRAM SIMM 16Mx32 4K EDO 60ns Tin >7chips
it is a non-parity 5V chip.

Not wanting to spend more than I need to I found a deal on generic
memory for $61.49 (http://www.asr-online.com/asr-online/memory.html)
the only caveat was that it was high-density and required a 4k refresh
rate and double sided.

Given the Samsung KMM53216004AK-6 specs and the intel memory spec for
the PD440FX the generic memory seemed to be 100% compatible.

However after receiving and installing the memory the following
happened:

First the machine booted and showed just 64MB of ram before writing
some small pixels to the lower left side of the screen.  I went into
setup and found that the bios (AMI 1.00.01.DT0T - Gateway specific no
upgrades available) recognised 160MB.  But windows wouldn't boot and my
CD-RW was not recognised.

So I removed the old memory and checked the new memory was in place and
rebooted.  This time the screen corruption was more noticeable and the
BIOS would not go into setup mode.  Plus the harddrive was not
recognised.

Fearing the worst I remove the new memory and replaced the old memory,
to find that everything was fine (once I told the machine that yes I
has lost 128MB :( ).


I have now returned the generic memory for the major brand memory
(costs another $100 but maybe this will work!).

My questions are:

1) Why did the generic memory not work?
2) Is there a limit to the memory recognised by the memory counter on
bootup?
3) Should the major brand memory work (given that the generic memory
and the Samsung and the major brand all have identical specs)?


Thanks in advance,

Mark Donoghue.
