Hi forjonny,

Shared means you're using the integrated graphics adapter. As long as that serves your needs, there's no reason to add a separate card. If you want to add a card, obviously the Optiplex 755 minitower is the easiest to add to. Is that what you've got?

Yes that is what I got and I have a DMS card with 256 ram on it. I have the video cord to use with this DMS video card for vga or dvi so this would give me more ram for the computer thru the video card. But do I really need it if my vga is being used and everything works fine? Would the 256 card help at all?

DMS card is not ADDING ram.  Even with PCI-E card and 8 gigs of ram installed the frame buffer is reserved. So you never get 4 gigs nor do you get 8 gigs when 8 gigs is installed.

If you want to have multiple monitors use a sapphire 7750.

That picture that you have is what I also have for a larger tower. They seem to have no memory on them. I guess I don't know what frame buffer is so I better read up on that.

I have a few of these: ATI Radeon HD-3450 PCI-E 256MB DMS-59 - the low profile for this Optiplex. So you are saying that these are not video cards or GPUs?

Well l thought shared meant that you are using memory from the system memory as well as any memory on the video card. Isn't that what shared means? Why would it mean that I am using the integrated video card? That does not make sense.

Its Shared but Its one way sharing like a gold digging girlfriend.  

You don't ever get the frame buffer back.

The 755 has onboard INTEL video. 

Even if you add a REAL GPU with REAL Ram that is NOT SHARED you

DO NOT GET the Frame Buffer Back into SYSTEM RAM.

I would recommend a specific sapphire Radeon HD7750 to improve Windows 7 Performance.

They make non GPU cards that Transmit from the PCI-E Bus that is integrated Video.

DMS is not a GPU its a video connector spec.

This card acts as a pass-through device between the attached display and the integrated video. It can also be used to configure a dual-monitor solution.

I do have 4 GBs on this Optiplex but adding this DMS video card with 256 mb memory would be better than using the onboard video card wouldn't it? It will use that 256 mb ram from the card won't it? Will it still use less system memory with this card installed? I am not going to use multiple monitors. We are getting off the subject. We're not talking about monitors.

DMS 59 is the Video Connector.  The Low Profile Radeon 7750 I linked is a MUUUCH Better Card.

The 3450 is an Obsolete Directx9 card and not supported for Directx 11.  Lowest card supported for Windows 7/8 (Directx11)is the HD5450.

The Intel Onboard Video in the 755 CANNOT BE REMOVED.(Integrated)

What is Dynamic Video Memory Technology (DVMT)?
DVMT is a concept used in the Intel® Chipset family wherein the optimum amount of memory
is dynamically allocated and de-allocated as needed for balanced 2D/3D graphics and system performance.

Pre-allocated (FRAME BUFFER) memory is the amount of system memory
(64 Meg or More) made available at boot time by the system BIOS for video.
Pre-allocated memory is also known as locked memory.
This is because it is "locked" for video use only (FOREVER)
and as such, is invisible and unable to be used by the operating system.

The maximum amount of graphics memory will depend on the computer's Chipset.
In most cases, the sum total will not exceed  224MB. PCI-E does not limit the graphics memory so users may see maximum graphics memory up to 1536MB used in some situations.

The latest Catalyst Drivers 13.1 DO NOT SUPPORT the Radeon HD3450 at all and will tell you that you do not have an ATI Card installed.

In order to Do Directx9 you will need the June 2010 Directx Patch Installed then the Legacy Catalyst Drivers for the Ancient 3450.

Yes, of course the Radeon HD-3450 is a video card. And you do not need a low-profile card for the minitower.

On Ebay they sell these ATI Radeon HD-3450 DMS-59 cards and they call them video cards. You are saying that they are not video cards. If a computer did not have an integrated video card onboard then will these ATI Radeon HD-3450 cards work as a video card as long as you have the dongle for one or two monitors?

Isn't Pre-allocated (FRAME BUFFER) memory adjustable in it bios? If so then why do you say that it is locked?

I am probably sell this Optiplex to a computer user that will not do anything fancy other than Internet stuff. So I am thinking that I can just take out the DMS card and use the onboard video card. It seems to run fine, do videos fine, it looks alright on the screen and doesn't crash. I am not keeping it for myself.

I have bought myself a barebones Optiplex 960 and put in a PCI-E 256 memory card and an Audigy card and two sata hard drives. It's a 3 Ghz, 4GB ram. I use it in my business of computing.  I just keep buying these smaller form factor Optiplex computers to sell. People like them because they are small and run fast. I get them around 2.6 ghz or higher and 4 gb ram with Windows 7. Seems like they all come with this DMS card in them and onboard graphics with the VGA port.

Maybe they used them in the airport where they have multiple screens.

BTW, nice chatting with you.

I know about the low profile cards. I have about 20 video cards in my collection.  Anyhow, I have another computer besides the Optiplex 755 with no onboard video card at all. I do have a PCI-E slot in that computer and AGP. Can I use this DMS card as a video card in the PCI-E slot and use a monitor and leave one side of the dongle hang unconnected.  I thought you need some kind of video card on the computer before these DMS cards would even work. I thought somehow they used the onboard video card and then uses itself for two monitors.  So if they will work without any onboard video cards then the DMS would be my video card, right?

The Suggested Low profile card comes with full size and low profile brackets.  It is REQUIRED because other 7750 cards use 2 slots wide will not fit into any 755 case.

The cards with the PCI-E connector and no GPU are for use with specific models but do not allow DUAL video from that card. DMS 59 is a Connector specification not a Video card Model.    Which Size model will depend greatly on what can or cannot be used.  The USFF can use None as it has no slots.  The TOWER versions are the ones with the most options.  Ancient Computers that use INTEL Graphics with Vacuum Tubes can set the Video Ram from 1 meg to 8 megs.  Later versions of INTEL Graphics DO NOT HAVE a bios setting to recover Shared video ram.  You never Ever get the frame buffer back.

The Silicon image cards act as a pass-through device between the attached display and the integrated INTEL video.  It is not DMS 59 it's DVI.

Ok, I got your answer 5 times. This forum is not working right because I keep getting sent back to this same thread with the last answer. So something is wrong. Besides you are not answering my question about using the simple DMS card for a video card. It looks like there is no ram on this simple card. It almost looks like a dummy but it does have some electronics on it. So again: Can this simple  DMS card be used for a video card? Do you need a picture of it?
