Why can't i get the new memory to work. It works in the other slot so I know it's good. I had a 1 gig and a 512mb working so I tried upgrading the 512 to a 1 gig and now I can only get one slot to work. It doesn't matter which one but I can't get them to both work at the same time now.

Make sure it is the correct ram for your computer. If you just added one ram chip then try swapping them and make sure they have a tight fit.

To test the new chip replace the old one with it and turn on your machine. If it doesn't see it then it is either bad or not the correct one.

Let me know how it goes.

Evo n610c Laptop
Maximun Memory 1024MB Non ECC
Unbuffered CL=2.5. DDR333
2.5V.
DDR PC2700
Number of Slots:
Slot 1 Slot 2
Each memory slot can hold DDR PC2700 with a maximum of 512MB per slot

I have the same laptop

try removing one of the memory modules and then try it again.

You can put memory in one or both slots, max is 512Mb Per slot total 1Gb

Have you tried reversing the two ram modules? Or better than that, install two new 1GB modules. And if you do not want to do that make sure the Slot 1 has the larger of the modules. Do you know that the memory modules both work?

Is the mainboard capable of supporting more than 3 GB?

If it is then maybe you have the wrong kind of memory, or the slot is bad.

Take all your memory out and just try with the new stick in one of the good slots. If it works then we know the memory is OK so then try it in the "bad" slot.

Seems the memory is not comatable with the motherboard. Replace the old memory and visit http://www.crucial.com, they have a scanner tool which will confirm what mem can be installed.

Hi,
You Can Actually Upgrade This To 2 Gig Memory.
Each Slot Will Take 1 A Gig Strip.
I,d suggest Buying another 256 mb Strip, To Put Into Slot 2.
Or Buy a 512mb ( Half Gig ) Which Will Give you 750mb With your Existing Strip Already In There. ** Recommend 1 Gigabyte Max** 2 gig of Ram in This Baby Would Probably Start Glowing.
You Can Buy DDR/266/333 In 256/512/1 Gig Strips. These Are Commonly Known As SD-RAM-Modules.

Check the owners manual of your computer for the correct installation of 2 sticks of memory, this can be critical on computers with 2 banks of 2 slots, it will also tell you the maximum ram that will work. If you do not have the manual, go to the manufactures website and then go to the support link, and browse for memory installation. BPCS

i had same problem with mine, i have the acer aspire ast180-ud360a, dont put the same memory next to each other, u have to stagger it, so it looks like

------------> [1gb] [512mb] [1gb] [512mb] <--- correct setup

and not like

------------> [1gb][1gb][512mb][512mb] <--- incorrect setup
