Need help finding a suitable low-profile video card for a Dell Optiplex 755 SFF

Like the title says, looking for a low-profile PCIe video card for use with a Dell Optiplex 755 small form factor system. I believe it has a stock 280w power supply. The system is equipped with a C2Q 2.4ghz cpu. The system will be used for mainly word processing, internet browsing, and Facebook. I know the integrated card would probably suffice, but I really want to put in a dedicated card if I can.

Best solution

Since you said the most intensive application for this machine is internet browsing I'd recommend

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

it comes with a low profile bracket and will run on you psu with no issues. It will also do all of those task with little struggle and may even do some light gaming.

Xroe,

I am trying to install a XFX Radeon HD6670 2GB low profile graphics card in my Dell Optiplex 755 sff and am struggling to get the pc to detect the card.......might there not be enough power from the PCIe slot (25w) to run the card? The fan is turning and so I assume it's getting power. Any help would be most appreciated.

Regards,

CG.

The first thing that I would ask is if you have installed catalyst. From there then I would begin to troubleshoot any other problems.

Hi there Xroe,

Thanks for the reply. Tried to install Catalyst previously.....version 8.0.915.0. Halfway through installation it fails, with the error message "Application Install: install package failure!" I have tried this with the card in and with the card out, and with the same result. Is it having trouble installing because it can't detect the card?

Also, with the graphics card located in the PCI Express slot, when I go into BIOS it states that there is nothing in the PCI Express slot (slot 1).

Regards,

CG.

The BIOS issue is strange actually, I can only assume that either your motherboard's PCIe slot is damaged or the card itself is damaged as I have never heard of the card being completely unrecognized. I would say to check device manager and see if it recognizes the card before agreeing with that conclusion though.

Yeah......I thought that too. Did buy the card second hand so maybe I got a duffer. Also bought the pc second hand so the PCIe might be bust too.....am planning to install the card into someone else's machine to see if it works. At least then I'll know a bit more.

If possible install it on a pc with a GPU already previously installed so you can know that it's PCI-e slot is in working order.

Thanks for the advice.

Have had a few issues with this new build where devices just aren't being recognised.....either by the bios or windows. Tried to install a replacement hard drive too, and have had to give up on that at the moment because when I connect that up to the second SATA port my pc doesn't boot, saying it can't find the first drive in the first SATA port!!!
I did pay peanuts for the pc, but looks like I might have bought a monkey......

Caj,

A Radeon HD6670 should work with my set up.........would have preferred a 7750 but am trying to do this as cheap and as good as I can.....

Have you disabled your embedded video chip in Device Manager prior to installation of 6670?
First you have to uninstal your video divers and catalyst, second disable embedded one, and last proceed with installation of 6670.
If this is not going to work let me know.

Hi Kisianik,

Thanks for replying. So you recommend I do the following:
1. Uninstall Video drivers for my Intel (R) Q35 Express Chipset Family in Device Manager (under Display adapters tab)?
2. Disable Intel (R) Q35 Express Chipset Family in Device Manager?
3. Reboot pc with Radeon hd6670 installed in PCIe slot?
Vista should then locate the card........
4. Install drivers from cd?

Regards,

CarelessGenius

Yes, something like this. When you are uninstalling Intel drivers, make sure you are uninstalling video drivers, and make sure that your monitor attached to Intel port.

When installing new card just follow instructions, disabling is a MUST, the rest is standard.

Hi Kisianik,

Uninstalled Intel (R) Q35 drivers, but then couldn't disable it cos it had disappeared from Device Manager. Should I disable it first, then uninstall drivers?

Two other things which are troubling me:
1. In BIOS, the PCIe slot 1 (where the graphics card is installed) is showing as 'empty slot'.
2. I cannot install the Catalyst AMD drivers as it crashes mid-way, stating "Application Install: install package failure!"

If my pc can't detect the card even in the BIOS maybe that means the PCI Express slot is faulty or configured incorrectly????

Regards,

CG.

Hm, interesting

You know, start new topic and drop here a link so I can continue thinking about it, in the mean time maybe someone else will come up with an answer.

You hijacked a topic, that is why you don't see others helping you a lot.

Having about the same issue... Optiplex 755 desktop, and I have an HD5450 that I removed from another Optiplex 755 tower. Card is fine, will not detect. Install of software gets 1/3 through and system restarts (Tried exe download, and the CD). Checked the BIOS and set to auto for video card detect (options are auto, or use onboard). Old card uninstalled as well. Wanted to use this as a basic media player but, not certain what's going on. Added video cards to 3 other Dell systems, had 0 issues.

EDIT - I right clicked the video card and updated the drivers that way using the downloaded file, said file wasn't readable or something, so used the CD and installed the drivers. Says installed, but when using something like HWINFO32 it shows that I am using the HD5450 drivers, but shows the onboard HD6370M/7350M/7370M...? But, now that it's using the proper drivers, I downloaded a new exe file from AMD's site, and did a full install no probs. Still shows the onboard card in HWINFO32 but assuming a problem with the app since I'm plugged into the card and drivers installed including audio... though started a thread because audio says its fine, but no sound.

THR,

My pc is a new build from a refurbished machine, and so in theory I should have no 'baggage' to uninstall first, apart from the generic dell stuff....however, the fact that the HD6670 is not being detected by any aspect of my machine makes me wonder if the PCI Express slot is faulty/broken, or it's a duffer card (I did buy it second hand off Ebay...).

I debated at first if my slot was dead or something as well, then realized if it was totally dead, I wouldn't be seeing anything on the screen. Though now that I have stuff running, the sound isn't coming through so... being that my system was used as well (off-lease) I wonder the same thing.

I have 3 Dell's here the family uses, another is a Dell 755 tower... I swapped the power supply out yesterday for a 430w I had laying around, and put my old HD5670 card in. The HD5450 is what I pulled out, it's only 4 months old and worked fine for my nephew who played games and such with it so, I know the card works in a 755. And no fan so, doesn't really need much power. That being said, in the 755 desktop I put it into today... it's been 6 hours of grief so far. :S
