Memory installation problem

Voy06 · 17 Dec 2011 at 16:09

Hi, I am wanting to increase the performance of my laptop (HP550 Windows Vista) . It is currently running 1gb of ram and I want to upgrade to the max 4gb. The memory installed in the laptop now is 1gb DDR2 SDRAM, SODIMM memory slots. I have bought 2 2gb DDR2 memory sticks.

When I startup the laptop after installing the new memory sticks I get a blue screen stating windows fails to start-up. If I take out the new sticks and put back in the original 1gb stick windows loads up fine.

As far as I know I have bought the correct type or ram so just want your advice really why is this happening what can I do etc.

When I started the laptop after installing the new ram I was given 3 options, Save changes, ignore changes and Computer set-up. I chose save changes, is that correct?

Any help appreciated.

Well it's unlikely it's down to faulty SODIMM's and given your laptop only has two slots you had to take the old memory out (hence no chance of old conflicting with new).

Hmmm. Are the two modules you bought the same make and model? What's printed on their labels? Your laptop supports up to PC2-6400 which is also known as 667MHz DDR2.

Could be an issue down to not supports single sided or dual sided SODIMM's but that's also unlikely.

Hi, yer the two modules are exactly the same. The label on the new sticks say 2GB, 200 pin DDR2 SODIMM 256Mx64. (PC2-5300)

Did you try only one memory module of the new ram.

I don't believe I have but I don't think that will be a solution. I'll give it a go and see what happens.
