Inspiron 580s, dedicated video memory

Video memory cannot be changed or upgraded. 

Why don't you pick another user name? Not applicable makes us ignore your posts.

you can't do that.

you buy more ram,(DDR)

and install  64bit OS. go over 4GB....

that is what everyone does,

that chipset intel  H57 owns lower ram,  (owns it)

one of the oldest 32bit DDR3 topics on earth.,  truly.

when you put any card in any PCI-e slot that needs RAM or ROM address space, you lose more DDR.

3.4 million hits on google, more really.

DDR on this old PC is dirt cheap now used,  why run 4GB? really?

IBM invented all this, back in 1981.,  ROM maps low, and memory DDR overlap there goes off line.

rule one on RAM , cant have two memory devices using same address and data space, or DATA COLLIDES !

things that steal RAM are , GPU, RAID CARDs, SATA boot cards,  etc.(lots of cards do)

ANy thing that needs ROM space or needs RAM , in the PCI-e slot will steal from total DDR space.

until gen 4 and is less loss, not 100% cure.

buy a Dell 3020 used for better fun.

this is the oldest topic ever on PCs,  the 4GB limit,  millions of hits world wide, on topic, all with the same 1 answers are easy.  

The OS task manager tells you the truth, did you look there first.

you have only 1 stick of  DDR 4GB ,  Running in channel A only slow mode? why? (put in 2 sticks and load 64bit OS)

PC is 2009 PC, 10  years old now. 580s the 's'" means small. sized case.

first off no OS stated, nor if 32bit or 64bit OS,  (click system in the windows control panel and see that)

This PC uses CORE gen. #

The PC runs core i3 or i5, new in the box PC.

H57 chip set, and can run 4GB min to 64BG max,  with limits,stated clearly in your users guide.  4 DDR slots!

The H57 has the uses old generation GEN 1 CPU, like I3-530 is.  and the rules  of lower memory are dicated by that CPU, iGPU is inside the H57 chip, the CPU can not use, memory used by the iGPU.

per the data sheet on BOTH.

•
4 GB - 1 x 4 GB
•
8 GB - 1 x 8 GB
•
8 GB - 2 x 4 GB
•
16 GB - 1 x 16 GB
•
16 GB - 2 x 8 GB
•
32 GB - 2 x 16 GB
•
32 GB - 4 x 8 GB
•
64 GB - 4 x 16 GB

now the short story,

the IGPU steals DDR RAM to run VRAM

the adding of  new GPU card, will not erase that.

you need  gen4 CPU to gain this magic. years later the CPU has magic DDR "adaptive technology logic inside"

you dont have HASWELL CPU, Gen 4, so you dont get this. what we do  is buy more DDR.

see the magic word here RE-Claim , ?

Must use Dell or PNY or Gigabyte or MSI LOW PROFILE Single slot card. GT1030 is the only thing that will work.

When installing an after-market graphics card into a Windows PC with UEFI secure boot enabled, the system may not boot.  This is true for ANY PC not just Dell.
