If the memory type isn't the same, i can download the related Bios here:If they have the same memory type, then yes it will likely work. Find the memory type by using GPU-Z. Memory types include Hynix, Micron, Samsung, etc. Do realize though, that flashing the BIOS will void any warranty you may have.
If the memory type isn't the same.. well I believe that Micron and Samsung can use the same timings. If it's Hynix then you have to have a BIOS with timings specifically for Hynix. I see there are three different BIOS on there for the Strix TOP 8GB model, 2 for Samsung and 1 for Hynix. So, yes, you could download one from there if your memory is different. Again, if Micron then Samsung should work. If Hynix then you have to have Hynix BIOS. It says it on the details page for each BIOS in that link you provided.If the memory type isn't the same, i can download the related Bios here:

Am i right? About warranty, yes i know, i'll also open the cooler for replacing the tubing lights, and the thermal paste. For flashing i've to use antiflash. Am i right? Thank you.
I understand your point i just want the oc version as a top version, even fan settings and maybe something else are different, and maybe i'll be able to an higher threshold of OC, if i flash that graphic card. I see so many people, flashing rx480s to rx580s without problems, so i don't think will be a risk, doing this thing... Maybe, if memory type is Micron, i'll avoid this.If the memory type isn't the same.. well I believe that Micron and Samsung can use the same timings.

And yes, ATIFlash is what I used to flash many BIOS a couple years ago. There is a chance it will not work and will "brick" the GPU. That happened to me a few times, but I was able to un-brick them using command line interface + atiflash.exe with a force (-f) command to force a bios flash. Even then it wouldnt' work every time and had to attempt it multiple times.
Honestly, you could just overclock the card and not worry about flashing the bios.
I saw them and they look the same to me. I don't know what the difference is.I see 2 version for samsung, but they looks the same.. Are them different?
I'm not in crossfire, i'm using them separately. I want to flash the oc version for getting same default settings as a top version. That means, increasing voltage, greater voltage limit from msi afterburner, same fan and external fan settings ( the oc version is more loud than top version) and maybe something more, i've to seee both bios. Probably, i'll sell one of them, so i want to get the one who gets better OC performanceBut....why?
The reason people flash RX480's to RX580's is that RX580 BIOS'es allow greater voltages. In your case, you have two RX580s. Just go into WattMan and tune the slower card up to match the faster card. 1411MHz is probably going to require about 1160mV.
Do yourself a favor, set voltage to Manual and undervolt both cards while you're messing around. Here's a guide and I can give you voltages to get started if you list out the frequencies of all 7 performance states.
Ok, i'm trying to use wattman now, I put directly the maximum allowed voltage (1200) and I start testing with Unigine. I also have a 120 fan on front of my graphic card, linked directly on the graphic card connector. If i install Asus Gpu Tweak to handle that fan, will it have conflict with wattman? I'm working on last state directly, to tweak the maximum frequency. The rest doesn't matter. Am i right?
- See the graph at the top of the WattMan tab page
- I honestly haven't played with fan curves since the default 75C target works for my needs. On my personal RX480 @ 1300MHz, that's usually = 1400rpm under full load.
I'm at 1500mhz with 1162v on asus gpu tweak 2. I'm using asus software because i want to handle the linked chassis fan as i want to do, and i'll use amd wattman for changing memory timings only. Can i do that? I think i'll not cause any software conflict.. I thought it was a safe operation, flashing the top bios in the oc version, however, as you say, it is better not to risk it. I will only use software like asus gou tweak to overclock them. Anyway, Asus Gpu tweak, allows me to get an higher voltage then wattman, over 1250v.The rest of the states matter once you start using power saving tech like "power efficiency", "frame rate target control", "chill", OR if the GPU starts to thermal or power throttle.
1200mV is probably good for 1450MHz give-or-take.
Monitoring the frequency and voltage on your TOP card will be a good indicator of what auto conservatively wants to apply at its default 1410MHz, then you can test voltage down from there.
I'll try to reach 1550mhz. Now, in Unigine Heaven i reach 1500mhz with 1187mv under full load, totally stable. I've to try with memory frequency now. My question is:IF 1500MHz is stable at 1162mV then you're pretty lucky based on my experience. Perhaps some sort of record! IIRC, ~1500MHz is pretty close to the max for Polaris chips.
I'd have to dig back into it to confirm, but increasing the "Power Limit" slider on WattMan may allow you to set >1200mV.
Yes, it is... Anyway, the last version of asus gpu tweak 2 is pretty good, gpu voltage control is a bit bugged, but i can easily fix it. I'll use wattman only for changing memory timings. What's the better value? Level 1 or Level 2? Do I have to change the timings first and then find the frequency in OC, or is it not important? Thank youIs the 120mm fan actually changing its RPMs during testing? May want to confirm this since it would seem that's the only reason you're sticking to Asus GPU Tweak. The benefits of adjusting a fan(s) speed based on GPU temps is obvious, but it needs to actually work....
I've found thisLevel 2 is better/ more aggressive.
Memory frequency vs. timing is going to be a give-and-take at the ragged edge where you're targeting, just like regular system RAM. Each timing setting will have a corresponding max frequency. At some point, you'll find that dropping to "Level 1" or "Auto" (loosening the timings) will allow slightly higher frequency, but I honestly don't know what balance of frequency and timings is going to produce the best FPS. AMD unfortunately doesn't expose (to my knowledge) what timings are being adjusted when you select "Level 1" or "Level 2" and I'm not even sure if there are any monitoring tools to see this either. If we knew that information, we could mathematically determine what the best combination is, similar to system RAM.
