I have a backup desktop that I use for managing files across my network. It is an old system but recently added 4 GB of ram and have a 980 I put in it to upgrade the 720 that is already there. It would not post with the 980 in it. The 980 is not on the official supported CPU list. I've googled this and even contacted Biostar concerning this question. Biostar was of no help. Nothing helped on my google search. I can live with the 720 but I know the 980 will be a bit more snappy. I'm running Linux Mint 21.2.
Question Anyone know if I can use a Phenom II 980 on a Biostar TA790gx 128M?

TDP of CPU versus TDP of socket on that particular mobo, vis-a-via the VRMs? I suspect the 980 might be "locked out".
It says it supports 125w CPU's. There is a BIOS update for C3 stepping CPU's. I'm 99% sure the CPU is good.

Did you update the BIOS? If you did and the system wouldn't post, you could try either looking for a modded community BIOS for the board, or possibly take out some of the RAM and see if the system would initially post with minimum components.
I haven't updated the BIOS yet, I'm always worried about bricking the system. When I tried the 980 I hadn't added the additional ram yet. I had 2x2 GB installed.

I would update the BIOS with the known working CPU, and then try swapping in the 980. As long as you are careful and patient when updating the BIOS, it shouldn't be that risky, especially if you have a UPS. Of course the method depends on the board, but generally it should be doable from within BIOS itself, or within a bootable DOS based application.
It looks pretty straight forward. I have the BIOS file on a thumb drive and plugged the computer into a UPS. I won't have time to get to it until after Christmas.

AMD Phenom II x4 980 Black Edition Review - Overclockers
Just when you think they're done, AMD ships another Deneb-based chip, saying "hey, we're not abandoning you just because Bulldozer is coming!" Clocking in at 3.7 GHz, the Phenom II x4 980 Black Edition is a speed bump over the previous x4 975 Black Edition.

Is it that chip?
Yes it's a 980 pretty sure it's the BE. I think they were all BE's.AMD Phenom II x4 980 Black Edition Review - Overclockers

Flashed the BIOS and installed the 980 and now got a sweet new top end Phenom II system.
Unfortunately it still can't handle 4k video playback. I have an old 5850 1GB in it now. Would a 7970 3GB help? It's running Linux. How can I tell if I'm getting hardware playback support?

I wonder if there is a possibility of using a 6 core Thuban Phenom II like the 1100T. From some quick searching, it appears both the 980T BE and the 1100T BE are 125W, so it might be worth a try to see if a Thuban would work. Though checking on ebay, I only see a few Thubans for under $50, which kinda surprises me.
As for hardware video playback, I am not sure on that. And I do doubt using a Thuban would make a big difference, I just figure it would be cool to have the 2 extra cores.

I also came across this thread https://www.overclock.net/threads/biostar-list-of-biostar-amd-phenom-ii-x6-ready-motherboard.707310/ Thubans are certainly not officially supported, but if you want, you could try one with the latest BIOS or with a modded BIOS.
I don't want to put much money into this system. I already had the 980BE which I had pulled from an old system so I popped it in.

It would be kind of cool.

Probably the 95W 1045T. You can sometimes OC to 3Ghz, with a good tower cooler.
Not exactly a higher-TDP "gaming" model.

I have 4 other upgrade projects going right now so probably going to leave it. As cool as a Phenom II x6 would be, I don't think there is anyway to get it to run 4k video smoothly. I'll try the video card upgrade just because I already have a few.
Why are BIOS's so stupid? After installing the Phenom II 980, I thought the system was just too old to handle 4k video. I have been using it for some simple file transfer tasks but it just seemed sluggish. Running Linux Mint 21.2. So I ran Speccy and CPU-Z and low and behold both show that it is set at a multiplier of 4x. So my stupid motherboard default set the CPU to run at 800Mhz instead of 3.7Ghz. Might have something to do with it's subpar performance. I have to get into BIOS and figure out how to get it running to spec. I'll still probably replace it but I might need it for the office at some point.

Without the help of GPU hardware accelerated decoding and encoding, processing videos especially HD, 4K Ultra HD videos, or 3D contents will place a heavy burden on the CPU.
Also you should expect complications if you are running an unsupported CPU. Seemed like that might be the case.
It is supported after flashing the BIOS. I have a 5850 in it now which supports the following. I have a Quadro K2000 not sure which would be better.
DivX
H.264
MPEG 1
MPEG-2
VC-1
Well you would need to know how your video was encoded.
H.265 is notably absent...
There was a program you could run to check encoding, I'll try to find it.
Most are H264 since I encoded them. I couldn't find what codex the K2000 supports. I'll look again. I don't want to spend anymore money on this system so looking to use what I have on hand. I have a GT610/GT710/K2000/4850/5850. The K2000 has 2Gb ram all the others are 1Gb.
