Latest Radeon driver for dual graphics support (APU plus GPU crossfire)
Latest Radeon driver for dual graphics support (APU plus GPU crossfire)
Everyone,
Initially I understood this technology is outdated and there are superior alternatives available. However, I had components reserved specifically for constructing a Dual Graphics machine equipped with an AMD A10-7890k APU and an R7 250 GPU some time back, and I'm only now assembling it. This approach can be seen as exploring something obsolete.
My inquiry: what is the latest driver (Windows 10 64-bit) that supports Dual Graphics, also known as hybrid Crossfire?
Background: I am certain the most recent version of Catalyst Control Center will likely function, but I aim to stay current. Searching online yields few helpful responses, and my communications with AMD were not very productive. I’m uncertain whether normal Crossfire support was discontinued simultaneously.
Thank you very much!
I haven't reviewed the release notes for these drivers yet, but perhaps some guidance is available.

Also remember that if a crossfire driver isn't available for Windows 10, you could use a Windows 7 64-bit driver in compatibility mode.
It should be possible to crossfire it, though it isn't a big option—it might feel a bit rough.
Someone managed to get it working on a laptop.

I wanted to inform everyone about the latest progress. I tested the previous versions of each "flavor" in the Radeon driver, starting from Adrenaline 2019 up to Catalyst, but nothing worked. The BIOS was configured for Dual Graphics, and I experimented with different cable connections (GPU or motherboard) and VRAM settings (auto or 2GB). I think the MSI R7 250 2GB OC might behave differently than a standard version. I’ll try again with a simpler card and update if I discover something better.
Here’s a revised version of your text:
A brief note for everyone, especially those planning to dive into retro PC building who might face this challenge:
there are two versions of the R7 250—one using the Oland codename with 384 shaders, and another based on Cape Verde with 512. From my research, only the Oland models are compatible with dual graphics cards.
I’m not sure how people used to distinguish them back then. I’ve tried two cards that turned out to be Cape Verde (verified with a GPU Z), but they didn’t work. I have an R7 240 coming soon for testing and another 250 from ASUS with just 1 gig of GDDR5. It also supports VGA output, which could be helpful. I’ll update the thread once I find a driver that works with this setup.
I understand this detail is old-fashioned and may not matter much, but I’m aware there are still many PC lovers who value classic hardware.
Final update and exciting news!
I discovered a 1gb GDDR5 model of the ASUS R7 250, which was Oland.
Additionally, the latest driver compatible with the A10 7890k still supports dual graphics/crossfire, and even lets you tweak the crossfire settings.
Version 21.5.2 was released on November 5, 2021.
For those interested in this route for enjoyment, I suggest checking R7 250 cards with either 2 gigs of GDDR3 or 1 gig if using GDDR5, without any overclocking mention, and include a VGA port. No assurances, but it could be useful.
Thanks to everyone for your support. This system, though outdated, is performing well—especially in crossfire games.
