Ram slot

Greetings my friend. Like 'Mike P', my dell has only two slots as well. There are several laptops that have four (4) ram slots. Lenovo, ASUS, some HP's and some dell's. I would suggest going to a website like newegg.com, or other computer accessory place,
and looking at their memory/ram selections. Reading their details should provide some insight as to the number of slots.

Of course, if your budget allows, the more ram you have, the better the laptop will be.

I hope this helps.

DIMM slot 1, 3 or DIMM slot 2, 4?


Page 1-23 in the manual;

System not detecting slot 1 with 4GB RAM.


I found the reason why the RAM in the other slot is not getting detected.
In laptop RAM slots the pins on the bottom connector are a little curved so that it can push the RAM to make contact with the pins on the top connector when we press-fit the RAM in its place. The fit is such that the RAM is held in place with all 204 pins in contact.
In my laptop, the pins on the second slot are not having enough curvature on the bottom pins. Hence, when I place the RAM in the slot and press it down, the pins never get connected to the top connector. Moreover the connection is so loose that I can easily slide the RAM out of place even after press-fitting it. So, the RAM is never detected! *Sad

Unfortunately my laptop is long out of warranty and nothing will be done by the OEM.
The only way I can now upgrade is to put an 8 GB RAM in the slot which is working fine (easier way) or get the RAM connectors changed.

Thanks for all your suggestions and help.
