adding ram to this computer

[laserman2005]

I want to upgrade the RAm in this compuuter. I purchased 2 sticks of 4gb of ram and when I installed it and restarted the computer it wound not start. Is there anything I should be doing before I install new RAM?

Thanks for any help you can give me.

Hi Jim,

Did you get DDR3 1333 Mhz RAM?

Try placing only one stick. Does it boot? Try the other stick.

Let me know,

David

It will run 8 gigs of RAM but its an i3-350M and HP laptops with that first generation of Intel Core processors are very very finicky about their memory. Most DDR3 memory you find in stores or easily available online will not work. It needs DDR3-1333 1.5 volt and it requires low density modules which means 8 black blocks on the side of each not 4.

This would work even though it says for Mac...no such a thing as Mac memory:

I did not have the DDR3 1333 I had the DDR3 1666. I am reording the correct DDR3 but want to know if the PC3 number is important. I have seen PC33 10666 and 10600. Is this an important aspect.

Thank you,

The PC number is just another way to state the speed. DDR3-1600 = PC3-12800...same stuff. You need DDR3-1333 = PC3-10660

[laserman2005]

Will PC3 10600 or PC3 10666 work?  It seems that is what is available.

Yes those are both the same as DDR3-1333 but remember what else I told you. Has to be low density 8 black blocks on the side of the module, not 4.

Thank you for all of the valuable information you gave me regarding the ram on this computer. I initially purchased the wrong speed and density and was rewarded with a screen that told me something was wrong but nothing else. You heve enlightened me and I want to thank you for that.

Thanks again,
