xfx rx480 8gb flashed to saphire rx580

The Sapphire BIOS P-States appear not to match the XFX cards power controller or some sorta of mismatch is happening? Going through and changing the voltage for each P-State (P5 to P7) with WattTool corrected the mismatched voltage to clockspeed steps for me. WattTool is unable to adjust the Memory clockspeed/voltage however so you would have to jump over to Wattman for that.

Afterburner works after I installed the 17.4.3 driver. All controls work as normal.
is it everything functioning normal? also i noticed you are using the 1450 bios. if that gives you trouble try the bios i provided.
 
i should also note that the only thing really working for me in windows 8.1 is just the driver. crimson control panel (or maybe its called catalyst?) does not install.

is the crimson control panel working for you? i am going to see if this is just a windows 8 occurrence due to their not being an official driver on amds website.

thanks
 
Just a reminder for anyone looking for answers, Please read the original post. I am updating it as new information is discovered.
Chances are that many of the answers you need are there.
Thank You.

Working like normal here for me. Not trying to rub it in btw.

Just seen your post after I already posted. Sorry about that. :oops:

its all good. im just waiting fr an official 8.1 driver from amd. glad to hear it works.
 
So the 1411 mhz isn't working for me, even with +96mv and +50% power limit. Not a surprise since I couldn't even get my card passed 1340 before. I'm starting to downclock, but started from the normal 1340 before, and without an extreme amount of testing, the highest I've gotten is 1360mhz with +96mv core and 50% power limit.
I guess I lost the lottery on this one :/

MSI RX 480 Gaming X 8GB >>> Sapphire RX 580 . Just flashed, no other tweaks. Before I overclocked the 480 to 580 clock speed to see if it works. Just played a CS:GO competitive match. Everything seems to work fine. for now.. Thanks a lot for this thread.

sorry to hear that. your asic quality is on the lower side so that might be why you are needing more voltage to get stable. are you able to get a higher overclock than before tho?

It is a little bit higher, by about 20mhz so far. Going to work the voltage down to compare the temps from before. If it's a decent amount hotter, I'll just go back to 480bios since 20mhz isn't worth the temp difference.

just flash.

i can cant really make out the photo. i assume the flash is working fine and the quality of the image just came out bad? if so mind letting me know the asic quality and model of card so i can add it to list of confirmed flashes?

thanks

fair enough. amd was saying that they refined the manufacturing process so i assume if peoples cards are already decent quality than this flash should work fine. good luck.
 
Isn't the RX500 series more than a simple rebrand? Thought I read somewhere that a few manufacturing tweaks were made at the node level. Surely simply flashing a BIOS isn't the safest thing to do?

they claim to have refined the manufacturing process and i do believe them. the rx580 bios allows more power draw and amd tweaked the voltage values inside the bios so that the card could run higher clocks. as a result the manufactures have updated the heatsink on many of there cards to accommodate the extra heat. their are some other tweaks that they made to also let the card more efficient when idle. i will need to confirm this tho.

So a RX500 series BIOS on an RX400 series card seems like a bad idea, then? Isn't it most likely the changes in the BIOS were made only because the node tweaks allowed for them?

to answer the first question, not necessarily. by refining the manufacturing process they most likely just made the overall quality of waffers they create able to run at higher frequency and except the higher voltages. this way they can make more higher quality chips at hopefully a lower cost and keep up with production. if they have a waffer that they want to use on a rx480 but it does not pass the quality control or make the cut they can often times disable many of the cores and use it in the rx470. this becomes a problem tho if your demand for rx480s is higher than rx470s and you cant meet the demand. many rx480s should be able to flash to the 580. they might need some tweaking to get stable but i believe most people who are going to be performing a bios mod might expect that. i personally did the mod for the higher stock clocks and, well now i have a rx580. i go over much of getting the card stable and making the necessary tweaks on the first page.
 
In my eyes, no, there was no refinement. RX 5xx series' ridiculous power usage is one that shows that.

The chip is pushed to its limit and it's leaking.

you might be right also. im going off of what i read. but the cores may be built completely the same just the manufacturing process was refined so that they could get better yields. they might have realized that the quality of the new waffers was good enought they could just overclock what they got and sell it as a new product. i did feel that the rx400 series launch was a bit rushed. heck, many of the reference 4gb rx480s could be flashed to 8gb models. theve had a while to clean the process up and the rx500 series might just be the result of that work. that would probably explain why i have not got a complaint from someone who had an asic in the 70s.
 
The overclock is really minor and it can already be done with RX 4xx. As someone on the board said, RX 5xx is AMD's Kaby lake.

i know that my card would not overclock 1350 but with this bios i am know at 1411. the 500 series bios allows more voltage by default. their are others on here who also are claiming the same. i agree that it feels like a kaby lake but some users have reported gains even when matching the rx480 clocks.

mtrai toward the bottom of page 2 goes over a perfect example of the voltage differences in the bios:
