Sapphire Radeon HD 6450 FleX 1 GB DDR3 PC: no signal Inspiron 660

Hello

replaced before the first start the connected with my Sapphire Radeon HD 6450 FleX 1 GB DDR3 PC (3 displays were used in parallel) which worked fantastic in the previous Inspiron 570. When you turn it on, no signal on one of the three appears.

My old system was a power of 300W power made a new one. Despite the support recommended 500W power supply I doubt that that will be the question.

Can anyone recommend to me what to do, please?

Thank you very much in advance!

If your computer came with Windows 8 installed and your aftermarket graphic card isn't UEFI firmware, you must configure your computer as follows:

Turn off your computer and connect your monitor to the original video release came with your computer.

Restart your computer. During the POST, when the DELL logo appears, press the F2 key several times until the Setup menu is displayed.

The arrow keys, go to the Startup tab.

Change of control of the Secure Boot to disabled.

Legacy OPROM support must be enabled.

Press F10 to save and exit.

Turn off your computer, connect your monitor to the graphics card of aftermarket and restart your computer.

  • Acer TC - 120 - PCI-e Sapphire Radeon HD 6450 1 GB working?

    Hello.  First post.

    I have a TC-120 Acer desktop computer, it works fine, but as I wanted to play a new generation of games I tried to install a graphics card, the Sapphire Radeon HD 6450 1 GB.

    When I have it insert into my PCI e slot I have no release the map or graph on the PC.  The turn came with a power supply to about 240 ~-300 W, I upgraded to a POWER 600 W PSU, but still the new GPU will give no output.

    The bios does not appear to include all the options of GPU or PCIe cards.

    Any help is appreciated.  Thank you people of Acer.

    aj8787,

    Your graphics card seems to be a riser.  Your BIOS is UEFI.  My advice would be to buy a UEFI graphics like gtx 750 or 950 gtx, but you will need to do some measure and research to see what card will fit as they come in different sizes. Some may be too big and not suited.

    To get your card HD 6450 inherited to work, some people have had success is UEFI/BIOS settings and disabling secure boot and activating "launch MSC always."  But do not know if it will work in your case.  And there are obviously some added security risk when you disable secure boot.

    Your computer works best with a new UEFI graphics card.

    It is also possible that you may need to update your BIOS. I'm not sure.

    Edit: I do not work for Acer and I don't have your computer model and I do not know what operating system you have.

  • What are the cards Radeon HD 6450 will work in a 620 Inspiron?

    I recently bought a MSI R6450-MD1GD3/LP for an Inspiron 620.  Well as I understand that the Radeon HD 6450 is a graphics card supported for the Inspiron 620, my PC won't start when I have this installed card - fans (including one on the graphics card), but the optical drive doesn't spin, USB devices don't you power, nothing.  Are there other Radeon HD 6450 - based cards that are known to work with the Inspiron 620?

    The ASUS EAH6450 Silent works in every Dell I've ever tried including the 620.

    The card has done a great job and has no problem playing here, to this day.
    I expect my system would be a bottleneck for the card but it works fine even with the PS of 300W.

  • Pavilion p7 - 1270t: Nitro Sapphire Radeon r9 compatible card 380 mother IPISB-CU of carmel2?

    I'm trying to update the graphics card on my computer Pavilion p7 - 1270t product # A5T37AV #ABA. The motherboard is the IPISB-CU Carmel2. What I have seen most of the new NVIDIA cards will not work on this motherboard because they need UEFI rather than old BIOS, I'm looking at AMD cards. My question is if the Sapphire Radeon Nitro R9 380 will work on this motherboard. Sapphire says that the card supports UEFI and BIOS legacy. I will install also a 600 Watt power supply which should be more than enough for this card.

    Update: BIOS version that I have is CAR_716.ROM vCAR7.16

    You are welcome.

    No, I'm not aware of such a list. at least HP.  It would be almost impossible for them to make such a list.  Even the manufacturers of video cards are not entirely sure that a card will work or not.

  • can I put a sapphire radeon HD 6670 2 GB in my HP Pavilion p6 2442ea?

    I'd like to update the graphics card in my HP desktop computer and I was wondering if it is possible to replace the Nvidia GT620 with a Sapphire Radeon HD 6670 2 GB? I understand that the power needed for the replacement of the card is a concern, but I have a 500W PSU on-site, just in case.

    Hello:

    I don't think it's your problem.

    With 8 Windows PC, the problem is that you go into the BIOS and change some settings when you add a video card no HP.

    Since you have your collaboration with the motherboard and the new P/S video, you should be able to change the settings and then add your new card.

    Don't forget first uninstall the drivers of card/video card nVidia current in the Device Manager, shut down the PC and install your Radeon.

    This link below will tell you what you need to change the settings.

  • I get the blue screen in the LR development mode, even though I have updated the driver for the graphics card on this new laptop. It's an AMD Radeon R5 M335 4 GB memory DDR3, core i7 6th gen processor. What should do?

    Hi guys, I get the blue screen in the LR development mode, even though I have updated the driver for the graphics card on this new laptop. It's an AMD Radeon R5 M335 4 GB memory DDR3, core i7 6th gen processor. What should do? Thank you

    This Eizo has a normal resolution of 1920 x 1200 pixels. I expect not to see a lot of benefits of using the GPU. You really see the advantage to screens that are at least 4K (3840 x 2160 pixels) or more. On small screens, you can see some benefits with smoother updates if you ONLY use the base sliders to develop. If you use brushes, turning on the GPU can actually slow you down a bit. In most cases, loading images in develop is also slower when you activated! There are a few illustrative notes to an engineer from Adobe that you can read here: notes for Lightroom CC GPU (2015) in order to better understand what is happening. Currently, in most cases, I recommend leaving off the coast. I think that Adobe is trying to improve and have more cards supported, but it is not yet completely there.

  • Radeon HD 7570 vs 7750 for Inspiron 660 s?

    I want to update my integrated Intel HD Graphics 2500 on my Inspiron 660 s, which has an I3-3240, 4 GB of RAM (which I intend to get 4 GB more), PSU 220w and Slim Case, a Radeon HD 7570 or 7750 which I just wanted to know which is safer to have with my diet and the profitability of this one. Thank you for your time and your response.

    None is validated and both use more power than a 6450 either kill your diet.  If you want to upgrade you must have obtained the mini lathe with minimum power 305 w.

  • Dell Inspiron 660 AMD Radeon HD 7800 series BSOD

    Recently, I have put my Dell Inspiron 660 with a new graphics card, an AMD Radeon HD 7800. At the same time, I improved the power source to a Corsair Builder Series CXM modular 80 PLUS Bronze certified ATX/EPS power supply 500W.

    I installed the card, update drivers and disabled the integrated graphics card. I tried to disable the onboard graphics via BIOS but there is no option to disable it in the BIOS, the AMD Radeon also is not running in the BIOS. If I uninstall the onboard graphics, the computer just re - installs on reboot.

    The card works for everyday tasks, but whenever I try to launch a game, it works fine without any problems for a few minutes and then crash with a BSOD. Then, the computer restarts and is as usual.

    The Inspiron 660 comes with the processor intel core i3-2130, 4 GB Ram and a 64-bit operating system.

    Any help at all would be much appreciated.

    Then, you need to get a more expensive food.

  • Sapphire Radeon problem

    I am running the latest OS El Capitan with a Radeon Sapphire 7950 GPU 10.11.6.

    I used a 27 "Apple thunderbolt monitor for more than a year with the GPU Sapphire and everything was really great.  However, I tried two screens.  So, I just bought a second monitor Apple thunderbolt and the second monitor turns with the above system.  If I try the new monitor by itself it will not work with the Sapphire card.  However, the new display will work when it is connected to my Mac Pro computer laptop running El Capitan. I did a disk repair system, compensation of LANDAU and a reinstallation of the system.  I tried changing the switch on the card, does not.  I had to connect with Radeon and hope they can find a firmware fix.

    All ideas are welcome.  Thank you!

    I'm confused on this monitor (s) you have.

    You say Thunderbolt, but the only Mac Pro which supports a Thunderbolt monitor is the end of 2013 Mac Pro.

    Note that the Thunderbolt plug will connect on a mini displayport mini displayport video signal being a subset of Thunderbolt

  • XPS 8700 and Sapphire Radeon HD 7870 OC graphics card

    I saw a thread on here stating that the AMD Radeon 7870 was compatible with the XPS 8500, so I guess that the overclockee of this card Sapphire version would work in my XPS 8700.  I inserted the card into my computer and connected the two power connectors 6 pins.  When I rebooted the computer, he made five beeps short and then put under tension (without the Dell splash screen, I think).  Restart again (and hear the same five beeps), I pressed F2 to enter the BIOS, but it wouldn't let me get into the BIOS.  The third time that I restarted, I just let it start and then after about half an hour of use, the computer is frozen on a blue screen (not BSOD). I turned off the unit and do not have reverse.

    I chatted with a few guys from Dell, which said that the five beeps meant that it was a problem of compatibility of video card, but he could not say more than that and pushed to me to contact Dell sales to buy a compatible card (no thanks).

    Anyone can check that the five beeps are told?  I hate to have to return this card to where I bought it and I'm not sure I can.  I get beeps if there is a driver problem that I'm missing?  Or beeps always mean a hardware problem? I'd get a beep if my diet was too weak?  Other thoughts?  Someone at - it no good they know maps work on the 8700 XPS?

    There was many problems reported with some video cards and the XPS compatibility 8300, 8500, and now the 8700.

    Make sure that you uninstall the drivers for video cards before you remove them and put in a new card.  Make sure that the power supply is disconnected and you have pressed and held the power button for at least 15 seconds.  You can also try to remove the CMOS battery.  Then install new video card, replace the battery and plug it back the power cord.

    In addition, connect the monitor to the integrated graphics card and restart.  Press F12 or F8 to access the Start Menu. Under the Start Menu, there should be a 'Change Boot Mode Setting' setting. This parameter will have the possibility to turn UEFI Secure Boot on or Off, change it to Off.  It is a common problem in Windows 8 that occurs when you try to add another video card due to conflict with Secure Boot and new motherboards UEFI where you post or get the beep codes.

  • Is the Radeon HD 6450 A 24/96 or 24/192

    I reformatted my Lenovo Q 180, and it is to show the supported audio 24/96 bit sound on HDMI. I think if I remember correctly, I saw HDMI support for audio 24/192. But I don't recall. Support 24/192? And if it supports 24/192 bit sound how to set up for 24/192bits? Help, please

  • An XFX Radeon 7850 will work on my Dell Inspiron 660?

    It is not the slim version. "The size of the graphics card are 7.8"x 4.4"x 1.5"
    I noticed that the hard drive uses space and limit to how long something in the PCI slot can be, but I did some steps and 7.8 length must adapt. However memory modules are worrying me. will they get in the way of the graphics card as they are really close to the end of the PCI-E slot? I already know to pass the power supply, so I have a Corsair CX 750. In addition, the graphics card will work on the PCI-E to inspire x 16 slot if the interface of gpu said PCI-E 3.0 x 16?

    Hi crayolaboy18,

    Thanks for the photos and links. They were very helpful.

    Modules of memory will not impede the map, so you can go ahead and get the upgrade. Its good that you upgrade the PSU too. Here take a look at the photo below, the graphic card XFX begins to protrude out of the base, which means that the body of the bulges of the slot card Express for PCI card locations. Thus, he will not come in the way of the memory modules.

    The red highlighted area above is taken by the card. And the answer to your PCI express 3.0 application is in the image below:

    I hope this helps.
