  Sorry for the late reply, I totally missed this thread.

  Anyway, specifically which model are you talking about? What's its SKU#. Sapphire make several Radeon HD 7750s, and just because one works fine doesn't mean that another will too.

  Which output have you tested? VGA? DVI/HDMI? Or both? If you haven't tried them all, then it's worth testing the various different outputs, including VGA from the DVI ports with a DVI-VGA adaptor.

  Do you have sam460ex_setup installed? If so, then its worth disabling it; if not, then try installing it (and adding it to your startup-sequence). Mozzerfan reported that removing sam460ex_setup solved his intermittent black screen on booting problems ( http://hdrlab.org.nz/forums/amiga-os-projects/show/105?start=16#post554 ).

  Unfortunately, there is no way that I can guarantee that all models will work. So, if you cannot get your card to work, then I'll add it to the compatibility list as a card to avoid (once you've given me the full details). You may want to have a look at the compatibility list, and choose a different card. You'll find that list at:

  Okay, please try installing the sam460ex_setup program, and let me know if that makes a difference.

  Also, I really do need the full details of your card, and by that I mean the full card name and SKU# (as requested above). See the compatibility list for examples of the information that I need. I cannot add your card to the list otherwise.

  Sadly, there is little that I can do to help you with this card at this time. Figuring out why your card doesn't work is like finding a needle in a haystack with the added complication that you can't see the haystack.

  Im thinking to buy another one videoboard ... about of your experience how will be the best choose for fast rendering 2d and 3d and future warp3d compatibility?

  The Warp3D driver that is under development will be for the Radeon HD 5xxx-6xxx range (excluding the Radeon HD 69xx series, as those are too different). Exactly which card depends on what you want, but I strongly recommend getting a mid to high-end card such as a Radeon HD 6670. The Radeon HD 6670 is noticeably faster than the 6570, and I have one that fits into a single slot: Sapphire Radeon HD 6670 Low Profile (11192-18-40G).

  hi Hans thank for your reply.
  Ok My card is

  Sapphire Radeon HD 7750 2Gb DDr3   Cape Verde/Pitcaim (Ranger info)
  sku: 11202-13-20G

  My motherboard is a Sam 460ex 1017ghz. Revison B (the redone)

  Uboot boot can see the bios loading and the setting setup ... but after loading the kicklayout modules the monitor goes in stanby and nothing more.

  Have you tried setting your sceen mode prefs to 1024x768 with your radeon HD4650 and saving them at this setting then try the HD7750 ?

  yes spectre , i change the resolutions , and try all the video exit on the radeon but nothing to do looklike the "vitualized amiga os 4.1 kickstart" crash or dont do the post... i dont know of to explain...

  I know there are too much variables , can be incompatibility with motherboard, with sam x86 emulator , with the radeon.chip too much variables...
  hope this can help hans do optimized his job for the future guys who will buy my same videoboard .
  I today ordered the hd 6670 low profile just because warp3d will be compatible with this videoboard and not whit 7750 ...

  I asked because I have only had two cards out of about 10 that did not show any Uboot with any output option or work at all on the Sam460ex. One of these two would show Uboot on a Sam440ep-flex but only work if workbench was 1440x900 or less. A third card works ok on the Sam640ex but would only show workbench on the Sam440ep-flex using a vga to dvi converter or if the monitor was powered off during AmigOS 4.1 boot and then turned back on after the boot jingle was heard. none of these were 7000 series cards though.
  The 6670 is a good choice for the Sam460ex The composite score on the 2d benchmarks are very good and I could feel a speed difference when I turned back on my Sam46ex after installing one for the first time. My OEM (HP) HD6670 model is quirky with the Uboot display. Uboot will only display on VGA output.I have both VGA and HDMI connected to the Monitor . Looks like it uses VGA output for Uboot and then switches to HDMI when Workbench loads.On My Sam440ep-Flex dvi output works perfectly with the same card showing Uboot and Workbench.
