AMD Help in underclocking or modifying 5500XT bios

[lordaine]

Hello, I thought it was the problem of the AMD drivers that most of my games crashes and it turns out, it was the boost clock of my msi 5500xt oc 4gb. When I underclock it to 1750, everything works fine now. No more issues at all.

Please, if anyone can modify this bios below, any help would be greatly appreciated. Just lowering the Boost Clock from 1845 MHz to 1750, or anyone can please point me to the right person. Thanks!

RBE doesn't support 5500XT for now

You may have a good day,

I will have a look at it,

At the meantime, after further research I found that the cause that prohibit flashing modified vbios is the RSA signature, unfortunately there is no easy way to modify this that is why the RX 5500 series is not supported by RedBiosEditor until now,

If I have succeeded in finding an easy solution I will update you whenever it is possible.

Hi,
were you able to look at my file?
In the meantime, I tried to change the straps the hiveos modified rom doesn't see it.
As I put back the original rom restarts.
Any suggestions ?

Hi,
Your file is fine however due to digital signature implementation by AMD, any changes in the vbios is not acceptable unless we modify the digital signature which requires skill, knowledge, time and effort.

do you know how to make these changes?
what software do you need?

Actually I am trying to locate the digital signature locations inside the vbios,
Please do not worry I am working on it,
I will update you if I have succeeded or if I get any information regarding this matter whenever it is possible.

a question, can you understand from the hex editor what the 1500 MHz straps is?

Somewhat, I found to be stable at 1600mhz and in the other hand disappointing cause I can't maximize the true potential of my 5500xt card.

I will send you settings that may change things for you to the better.

I will send you the hex offsets for the memory and their location, after that use the amdvbflash 2.93+ to try force flashing the vbios using -f to bypass the rsa signature as the 3.04+ doesn't support -f command, and do not worry 2.93+ support Navi 10 and 14 as well.

Ah, then I can't thank you enough

You are very welcome,

After I finished I will send it to whenever it is possible, I am going to work on them now.

Have you made any changes in the MorePowerTool as I see there is no changes in the .mpt file that you sent me.

No, for the moment i need to change only straps for mining

For testing we need a simple modification in the MorePowerTool like increasing the memory maximum clock from 930 to 1000 under overdrive limits tab.

Greetings,

Thank you for the files,

I might have figured out a solution however I need your help to verify it by testing the modified vbios files with optimized memory timings, if it is a success that will be a great thing,

I will update you whenever it is possible.

I am happy to help. I don't like to exploit others; I like to understand what to do and understand how it works.

Please do not worry, everyone has the right to get the knowledge, especially for those who knows how to use it properly like your kindself, I will explain things after verifying it is working.
