RAM problem

[cegparamesh]

My friend bought a Tiger Direct computer about a year ago and just
recently decided to upgrade the ramm from one gig to two gigs. The
computer uses is 2700 333Mhz ram. I removed the two sticks of 512MB and
replaced them with two individual sticks of one gig ram. The computer
turned on but did nothing else. When I replaced the new ram with the
old ram the computer turned on and worked fine. I then decided to put
all four sticks of ram in and the computer did not acknowledge the two
new sticks. What am I doing wrong?

Even though I probably won't be able to provide the ultimate answer, it
would probably be helpful to mention the type of cpu and mainboard in the
computer. I suppose it is possible that the motherboard is not able to
access 1GB RAM chips, or that it needs a bios update in order to be able to
do so. The manual for the mainboard would be the first place I would look
for an answer. Hope this helps. Good luck.

At a guess I'd say you bought "high density" chips? Only a very few
computers will use it. Most will detect half of it.
eg. 1g stick shows as 512megs
There's a chap in Hong Kong despatching mega-loads of the high density ones
without much information. Be careful!

Likely the 1GB sticks are higher density than the board
supports.

For future posts, it would be more useful to know the
details of your system, since "Tiger Direct computer" isn't
so useful. Details such as motherboard make/model, CPU (as
it relates to memory bus), and motherboard chipset are
relevant in this context.

For future reference, it would be better to buy PC3200
memory as it is compatible but has more stability margin
than PC2700. I suggest you visit http://www.crucial.com and
use their memory advisor tool to determine what's needed,
after the motherboard make/model has been determined.

You are trying to use memory that the computer can't access - it might be
limited to 512MB per slot, or it might be limited to low density memory
modules. Give us the motherboard make and model and we can probably advise -
or check the motherboard manual, or search on Google for the motherboard
model and see what the online manual says.

That motherboard apparently is not designed to use 1 GB sticks. It is
limited to 512 MB sticks.

I read the box that the computer came in and it says it has a D865GLC
motherboard and a P4 3.0 processor. I went on the web and the
motherboard supports up to four gig of ram. It also says it supports
333Mhz and 400Mhz but the computer box sent 333Mhz ram. Is it possible
to move up to 400Mhz or does it depend on other equipment in the
computer? It also said the memory to use has to be non-ECC.
