Do I need to do anything to see new Ram in a Windows XP machine?

Do I need to hold down a key at startup or do something else to get
the computer to see the Ram?
I got some 2 X 256MB Non ECC Non Parity Unbuffered SDRAM
PC Rating: PC133 EDGE Brand 168PIN. I assume it is what my HP
Pavilion 7915 Desktop PC, I replaced the 128MB with two 256MB and it
would not boot. I put the 128MB back in with one of the 256MB and tit
booted but only showed the 128MB in the system control panel. I tried
the other Dimm with the same result,

Do you get a screen at all so that you could possibly get into the BIOS?
Perhaps you need to look into the manual for your computer and see how to
reset the BIOS by using a jumper on the motherboard.
Have you tried the original ram in both slots (one at a time of course) to
make sure both slots are good?
Check out this link:
http://www.tomshardware.com/forum/10068-2-upgrading-pavillion-7915
According to that , high density ram will not be recognized by the 7915,
only low density ram.
Count the chips on your new ram to see if there are 8 or 16.

PS: It should just recognize the memory by itself, if the memory is the
correct type for that motherboard.

You have to check the Slolts of Your RAM. It may happen that slots
will not read the RAM. Will your Computer Boot with single 128 RAM
slot.

I actually tried to post this yesterday, but it never showed up, so I'm
trying it again.

The computer beeps a few times which is new and the monitor lamp stays
yellow so no screen of any type. And have tried both slots with the
old 128MB Ram and they both work.
Ok HP says nothing that I found on the spec page as to low or high
density Ram and yes the Dimms only have one side of 8 chips on the
board! So I think you have narrowed down the problem wouldn’t that
make them a Simm? And thanks for even finding a Ram seller that has
what I seem to need.

The beeps can tell you a problem. You can search for what they mean
according to the maker of the BIOS. (Google beep codes )
I really believe that the problem is that the ram you bought was 'high
density' and that is what the problem is.
Hopefully the return shipping charges on the ram you bought aren't too much,
as I noticed that the ram 'may' have been guaranteed to 'not be defective',
but I'm not sure it was 'guaranteed to work on your computer'.
Post back if you do get ram that works and if you think the increased ram
helped a lot.

There are probably better prices on the ram you need than the link I
included in the earlier post.

I suggest scan your computer with Crucial tool by going to here:

<http://www.crucial.com/uk/?click=true>

Or you could download CPU-Z tool from here:

<http://www.cpuid.com/cpuz.php>

The latest version of CPUID is: 1.53 and it will tell you everything about
Mobo and Ram.

Make sure the sticks you buy are stated as being low density and NOT
high density.

The lower the CAS value the faster the chip. Most of the PC-133 chips are
either CAS 2 or 2.5 or 3. (2 is the best, though I doubt you could tell the
difference in real computing time though. If you plan on overclocking the
cpu however, then it is worthwhile making sure the ram is CAS 2.

If you are in the US, here is a link for low density ram with free shipping
for $7.65/stick of 256MB. (it said free shipping on the Pricewatch.com site)

http://www.upgrade-solution.com/detail.cfm?show=yes&PID=107&add=yes

But beware of real shipping charges and burn-in charges that may apply.
Please read carefully before agreeing to buy from any site.

Here is another site for $4 sticks with $4 shipping for a total of $12.

Can't vouch for any of the sites which my links point to.
