Windows 7: Dell Inspiron 1721

Dell Inspiron 1721

Hello Again,

Most of you know and remember me from the Dell Inspiron 1721 problem installing Windows 7. I was successfully able to install 64 bit Windows 7 after working around some things, but now I have a new question.

I have a AMD Truion 64x2 processor and currently running 3 gigs of ram, (2.75) usable. My question is...

How much ram can my 64bit laptop recognize and use?

Would like to know before I buy more ram.

Since you are running a 32bit OS, your OS can recognize all the 3 GB RAM. If you add one more gig, it may not recognize as 4 GB. Instead, it will recognize
Total RAM-Video RAM.
For ex: If you install 4 GB RAM and you have a 512MB Graphics card, it will recognize 3.5GB RAM.

You can install up to 6gb on the Dell Inspiron 1721 laptop

While Dell indicates an official max of 4gb for the 1721, through much investigation, I had learned that the 1720 (based on the Intel chipset vs the 1721 AMD chipset...otherwise same chasis) could actually work with a 2gb chip + 4gb chip in either memory slot. I had 4gb of RAM installed upgraded some time ago from the original 2gb when the machine shipped initially. Trying to speed up this older laptop as a secondary machine, after removing Vista (which was so bloated, I could no longer use the PC altogether) and loading Windows 10, plus adding an SSD as the primary drive (keeping in mind that you will only get 1.5 read/write speeds from the SATA I hardware configuration, not 3.0 as with SATA II or even 6.0 from SATA III; still, the numbers show 4x increase in speed read/write improvement over a standard HDD), I had decided to purchase a 4gb DDR2 chip, installed it in RAM slot 2 (easier to get to it on the bottom of the laptop rather than removing the keyboard for slot 1) and after several tests, the total 6gb is fully working and the system recognizes it well while able to utilize all but the 256mb reserved for additional graphics memory. It apparently will not work with 8gb from what I have read in the that the bios and hardware support just shy of that and there are no other memory configurations in between 6gb and 8gb. Still, the extra 2gb beyond the 'supported' max makes the machine run that much smoother!

No, they actually never did. If you start with a Google search and hit Wikipedia, you will see under the Inspiron 1720/1721 specs that the 'unofficial' specs do support 6gb...Dell has long since retired the machine and their last specs remain the same at a total of only 4gb supported. FYI---I am using the last BIOS update of A07 for the 1721.
