It looks like power managment works fine, fan on my RX 550 slowed downed and now I have almost completly quite computer :).

I'm considering to get Radeon HD v5 driver, but I can't add it to the cart at AmiStore (I found it by searching for it, but when I add it, and try to check out it is not in my "bag" anymore). Strange.

If I can get my R7 240 (or 250) work (v5?) and there will be power managment for it I think right now it will be best choice, since I can have Uboot and possibly I can try to make Linux/MorphOS work on my Sam.

@Spectre660

Is there a way to get V5 for Sam460? AmiStore only have versions for X1000 and X5000.

Another quick update. I got RadeonRX 550 and it works well and power management works - I mean I HOPE it works, I can select options, but I'm still getting error about "configuration being wrong or something similar to that) :).

I still can't get my R7 240/250 work under AmigaOS, but there is a chance it will work with new driver (is there any way to test it before purchase?).

I'm thinking to try Linux so for that it would be nice to have R7 work under AmigaOS, so I will not need to swap graphic card constantly :).

Beside that it is quite nice AmigaOS machine :). Now, it is time to install software, configure it, etc.

I will bother you later ;).

@Spectre660

Thank you! It works now. Looks like installer from Enchancer did not add this line to kicklayout file, driver was copied there already.

So, RX 550 works great, all my Radeon HD works fine with exeption of three R7 240 and 250 will not.

So, I got MSI Radeon RX 550 and it will not work with my Sam460. Black screen. System boots fine if I swap to my 7750.

Is there anything I need to change in a Uboot/AmigaOS before swapping GPUs?

@Hans

I'm little surprised that various software/driver developers don't have a donate "button" next on thier websites.

I was wondering if Os4Depot could add "donate" button next to download. I'm using e.g. driver for Sound Blaster or it become to complicated due to various issue due to donors wanting e.g. refunds), sure it free but even if I wanted I have no way support it. Or take e.g. ignition development.

Not my area of expertise.

Your work (I hope!) is supported by sale of Enhancer /v5 driver, but what about supporting RadeonRx development? Is it going to be sold separately as RadeonHD driver?

@Hans

Can you set up Go Fund me, Patreon etc? or something.

Again, thank you your advices. I'm thinking of getting serial cable, just for a sake to be able diagnose things, and post here.

BTW. Radeon 5450 is like $15, it's basically price of the cable, sure i need to swap graphics cards, but with a cable I need a whole laptop 😋.

@Hans
I have the solution! Just make a graphic card for AmigaOS from scratch and charge for drivers development when you sell this graphic card. Genius idea! 😁

@K-L

I think it's a cost of improvement.

@kas1e

I don't mind not seeing Uboot, there us not much to do after it's working. I actually would not mind to have an option not to see it at all, I guess Rx 550 should fix that 😁.

Its like on a PC, new bios basically allows to skip all this "essential" technical data. I'm so happy I don't need to wait for memory test to be done before boot!

@geennaam

Great, thank you letting me know. I think it is going to be little more future proof 🤔.

Hopefully there will be more development of drivers for RadeonRx. Why would not everyone use this instead of Radeon HD? Linux? Morphos compatibility?

OK, thank you for correction.

I purchased rx550 yesterday, so I'm keeping that one. I will let you know how it will work when I will get it. I think I gave up on Linux/MorphOS on Sam so RX 550 will do.

I just want to have a power management, 55W TDP is not bad, but doing literally nothing and using that much electricity is little to much.

BTW. rx 550 is such a overkill for Sam460 🙄.

@Raziel

Im using Sam460.

@Amigo1

Thank you.

I have to say this is the most confusing thing EVER.

Is there any place where is this described? What is supported or not? What features or not?

I don't mind getting v5 but if I will pay $50 and both of my cards will NOT work, can I get refund? 🙄

@328gts

I tried. I burned CD, I made SFF/00 boot partition, copied the ub2lb as boot loader, I clicked Install Ubuntu Mate 16.04 - Sam460". It will start booting from a CD but after a while it will reset and start again.

Thank you for suggestion. I literally tried that yesterday night (was reading the Radeon v5 thread), same issue persist.

I'm getting rx550 most likely.

OK. It seems that rx550 will be my best route. My understanding iż that RadeonRX driver from Enchancer 2.2 will be sufficient for this card? No need for Radeon HD Driver?

Also, just to confirm with rx550 I will not have access to Uboot menu? I think I can leave without it 😉

Will power menagment work for Radeon 7750? Right now it seems to give me an error and no any settings are visible (I saw some screen shots with Balance, Performance etc. not for me). It looks like GPU is running on max clocks just running desctop.

Do I need to reinstall something after replacing Gpus constantly?

Also, I can't get r7 240 or 250 work with 3.7 driver, system will freeze when I click on an icon or dock.

Should I get rx 550 for my Sam460le, to have power menagment and better overall compatibility?

Also, will v5 help with 7750 and or r7 240/250?

Good to know, I'm just hoping it's not my Sam460 having some issues.

RadeonHD 3.7 and RX I think 2.12.

Side note: When I used drivers from Enchancer 2.2 on my 5450/7750 Candi was using about 15% CPU for both GPU. When I updated drivers (there was newer version online) when Candi is running on 5450 the CPU usage it's ~90% (!?), but when I switch to 7750 it's ~15%.

@Spectre660

I tried to boot from SD card. I belive this is the most "clean" AmigaOS4.1 (just added the drivers) and still the same issue. I can click window to start Amiga "live CD" and it will load properly and after that when I try to click on something, system will stop/freeze.

So, should I get version 5 of this driver? I'm not sure, if I really need it (?). Right now I'm using 7750, I'm not sure if I will "gain" much more from RX. Only thing I can think of right now is power efficiency.
