I currently have one RAM card which is 512MB DDR400 PC3200 and I wanted more
so I looked in my mother board maual and it says the max it can take is 3
DDR333 cards. So I recently bought a 1.0GB DDR333 PC2700 with the intention
of buying 2 more later. I swapped old for new card and the PC froze on the
first Boot screen so I turned it off and tried the old card and the PC booted
ok. So I tried with the new card again and the PC did it's beeping as if
there was no RAM at all. So I turn off make sure the card connected properly
and I got the beeping again. Then I tried both cards together and I got the
same frozen boot screen again.
At the moment I'm stuck, is there a special way of installing new RAM? Have
I got the wrong type of RAM? Please Help

You need to buy RAM that is specifically designed for your computer, and you
need to buy good quality (e.g. not from Walmart) RAM.

To choose wisely, go to the website of one of the quality manufacturers and
use their RAM selection tool. For example: Crucial (www.crucial.com).

In the bios of the computer there is a setting to allow the computer to
adjust according to the information that is embedded in the RAM stick. This
setting can/may be altered. If it has been altered to lock permanently on
PC3200 when you install a PC2700 stick you will be overclocking the new RAM.
The computer may well fail to even boot under this circumstance.

Use the old RAM, enter the bios. Make the necessary adjustments and save and
exit. Shut off the computer and put the new RAM in. It should now be
detected correctly and allow you to boot up the computer.

Thanks Urban,

Do you mean the CPU clock speed? If so I'm uncertain of exactly what to
change and if I get it wrong I think it can damage my CPU? I'd be greatful
for any more info as I'm not exactly an expert when it comes to changing the
BIOS

thanks

My FSB (front side bus) speed is 400 meg. If I tried to run my 1 gig of PC
2100 RAM at the synchronus setting I would, in effect, be trying to run my
133/266 RAM at 400 meg. I guarantee that my computer would not boot and may
even damage/corrupt the bios chip. The RAM just can't run that fast (a
severe overclock).

I have to be certain to have the RAM speed detected through the SPD - the
internal RAM information to set the RAM speed. If I choose to set the speed
manually I have to choose a setting which is a percentage of 400 that equals
266 (400 meg * .665 = 266). So, I am running my RAM at 66.5% of the 400 meg
front side bus, not in synchronization which would be 100% or 400 meg.

I hope I am clear. If not, someone will jump in to help out here! (-:
