Graphics Card Upgrade - SAM 460

@Spectre660

Received my Single slot low profile Rx550 yesterday.
Lower performance than my other card but should be adequate .

I try a sapphire R7-240 with 4 GB pci-e graphic card in a SAM 460.
Got the u-boot to appear,then the Workbench main screen then it crash when you use the mouse.

@Tuskagee

AFAIK those 240 models don't work properly on SAM460.
I have a 250 model and it doesn't work niether
I bought a few months ago a RX550 (polaris 12; see previous post on this thread for exact model) works ok, no Uboot output, but Workbench shows without problems.

I asked AmigaKit to help me find a new graphics card for the SAM460 and they've sent one in the post. Will I need to install drivers for it in my current system before installing it physically? They sent me a Radeon R7 240, but after reading here I'm worried it won't work, although I doubt they'd send a card which was not supported. I presume I should get one of the Enhancer packs for this one? I still find the whole thing with the different Enhancers and Radeon drivers and the lot quite confusing, even after reading thread here on Amigans. Thanks in advance. :)

Unfortunately with video cards "Supported" and "actual working on every AmigaNG model" are not always the same thing.

@Spectre660

Thanks for the info on the cards.

I've tried the card now. It is a VTX Radeon R7 240 with 2 GB of RAM.

Have the Enhancer Plus (the one available now) with the RadeonHD driver installed.

The OS boots to Workbench, but after a second everything freezes.

When booting with no startup sequence, I can type in commands etc., but as soon as I try to run a program it freezes again.

Have tried VGA, DVI and HDMI.

Only thing I haven't tried is buying and installing the latest Radeon HD drivers from the upgrade pack they are offering. This pack contains RadeonHD 3, while the one with enhancer is RadeonHD 2.

Now I'm back to the old card, which works well except for 3D. :)

@BobSacamano

The Freeze is known and subject of an old bug report.
Current suspect is the Sam460ex U-boot.

I have an AMD Sapphire Radeon 6450 in a Sam460ex with Radeon HD driver 2.22. It works nicely so far, it's half height and passively cooled but I don't think it works with Warp3D Nova. Everything else works though. Does anyone know a better card that is still passively cooled (i.e. silent) and half height/low profile?

The main problem I have is just HDMI port does not work, but DVI does so I can still use that.
