Upgrading Ram memory in Laptop: Need help

What operating system are you running? Also, does your BIOS detect 4GB RAM? Also check if your motherboard allows the memory remapping option in BIOS. If the BIOS does not report 4GB, you will have to check whether you have installed the new chip correctly.

If your operating system is 32bit; it will not detect 4GB RAM; I think it maxes out at about 3.25GB (needs confirmation).

If none of that works, you should test your new chip and ensure that it's working fine.

Its windows 7 os 64 bit... and bios says 2gb only... @#-Link-Snipped-#

I checked there is nothing wrong with the Stick... its working if I use in primary slot. @#-Link-Snipped-# how Can I check motherboard support or not and I checke many sites and dell as well. Everyone says dell vostro 1015 supports 4gb in 64 bit system.

Then may be there could be something wrong with your slot. What you can do is, remove the stick from the slot which detects the stick properly and just boot with the stick in second slot where you're having the trouble.

The limitation is on how much RAM 32 bit OS can use. Despite, it'll show the available RAM even if its not usable.

Yes, I think some thing is wrong with the extra slot...as I tried to boot with this extra slot by putting a 2b stick in it... and system decline to boot as it was unable to detect the ram... SO now I am damn sure that....

1. Either something wrong with the extra slot

or

2. the this extra slot can only take 1gb or other type of ram....??

Now I need to know what should I do...???? Please help @[Prototype]

I can provide you the extra information ..

its Dell vostro 1015
service tag is 8x81dn1

Well, the laptop should ideally support upto 4GB of RAM. However, in any case, restricting a slot to have particular amount of RAM is not possible. The slots are standard DIMM slots and doesn't impose any such restrictions. The restriction is put by other factors including the processor, OS etc.

So, if you're just putting 2GB of RAM in either of the slot, it should work. If it's not, there's certainly something wrong with the other slot. I doubt that your laptop is under warranty as its pretty old model, so you may take it to a local repair shop to get it inspected.

Where are you looking for usable RAM? If you could provide a screenshot it'll help.

Are you using windows 7 starter??

No its windows 7 basic 64 bit and it showing in system properties...

@#-Link-Snipped-# its w7 basic 64 bit...

Never noticed it showed that... 😀

Anyways, go to msconfig -> Boot -> Advance Options and check if you've checkbox ticked in front of "Maximum Memory". If it is, then uncheck it.

Both are like similar. These OS don't support more than 2GB RAM (on certain platform). You should better upgrade your OS to higher version or Linux 😎
