Basically, I have a machine at work where I have an AMD Radeon HD 5450 and an ATI Radeon HD 2400 that I'm trying to get to play nicely together for a four monitor display, but I can only get one card to work at a time, and it seems like a driver issue. Any advice?
Here's the template information:
- AMD Radeon HD 5450; ATI Radeon HD 2400 (Microsoft Corporation WDDM 1.1)
- No overclocking
AMD Catalyst Driver Version, and Driver History
- I have tried both 13-9_win7_win8_64_dd_ccc_whql (which gets the HD 5450 working) and 13-1-legacy_vista_win7_win8_64_dd_ccc (which got the HD 2400 working, but not the HD 5450)
-Windows 7 Professional Service Pack 1 64-bit
- This is a machine at work; I would like to hook up four monitors for display. All I have at the moment are these two cards, but it looks like the Catalyst system doesn't have a version that supports both; so I was wondering if there was a way to simply get the drivers for one and not go through Catalyst.
-I currently have the AMD Radeon HD 5450 working with 13.9 Catalyst install; but the ATI Radeon HD 2400 has a persistent Code 38 (previous driver version installed in memory error); meaning that when I restart, it does not go away. When I uninstall it, it tries to reinstall, but comes up with a persistent message to restart my system, which does not work; when I uninstall 13.9 Catalyst and install the legacy one, it works, kind of, but does all kinds of terrible things to the AMD Radeon HD 5450.
- I'm wondering if it's even possible to have these two cards running in the same machine at the same time, or if I should just give up and put in an order for another card that's covered by one of the two series of Catalyst.
Motherboard or System Make & Model
- Dell Optiplex 990
- Working from home at the moment, so I'm not 100% sure.
Display Device(s) and Connection(s) Used
- Working from home, so all the info I get is the RDP Channel, but they are all identical Dell monitors; each hooked up through a DVI splitter and set to extended display, for whichever card is working at the moment.
Applications and Games
- Just base Windows; I can only get one card to work at a time.
- Intel i7-2600 @ 3.40Ghz; no overclocking
Motherboard BIOS Version
- Dell A07, if memory serves.
System Memory Type & Amount
- 16 GB
- Nothing that should affect this.
- I've run MalwareBytes, Spybot S&D, and the company's antivirus, all have come up clean.
- As they work one at a time, I know the hardware is good; I just want to get the drivers to work together so that they both work at the same time. Or have it on good authority that this is impossible.
