Title: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: kilo17 on October 21, 2016, 04:07:44 AM Looks like some people just think they are better than others, that shit bores me. I thought I would create a thread and help people with ROM's that are like me, less intelligent than the "almighty" ones here on the forum.
This is a mod I made today. It gets 125w at the wall. Stable for a 6 hour run. I have tons of different 470 and 480 cards and will try my best to help people. I have a few rules I will apply: 1 - I will put people I know and those that contribute to the community in a positive way first. 2 - Higher rank accounts will get precedence over noob accounts. 3 - I have a life and will help as I can. 4 - I do NOT use DUAL MINING and do not test it. Tips are appreciated but not required. I ask you not to share the ROMs I provide. Thanks Proof is in the pudding: https://picoolio.net/images/2016/10/21/Screenshot_35a960.png Title: Re: RX-480 - 31.3 mh @ 125w Modded ROM Post by: hendra147 on October 21, 2016, 04:16:27 AM i will apreciate if you can share more detail to me in Private message for trying your setting, and post the result. of course i will not share the room.
i have some vga, powercolor rx 470 4gb , saphire nitro rx 470 4gb and 8gb, and rx 480 refference. just asking, your mod is running smoothly in all card ? because each card have diffirent assic stat's Title: Re: RX-480 - 31.3 mh @ 125w Modded ROM Post by: kilo17 on October 21, 2016, 04:16:55 AM If you have a large farm and would like a good software to manage it, please look at AwesomeMiner. It is easy to use and manages up to 5000 rigs. Also you can load any mining software you want with it.
I bought the software and use it but have zero investment other than trying to help patrike that puts a lot of work into it. https://bitcointalk.org/index.php?topic=676942.0 Title: Re: RX-480 - 31.3 mh @ 125w Modded ROM Post by: kilo17 on October 21, 2016, 04:21:40 AM i will apreciate if you can share more detail to me in Private message for trying your setting, and post the result. of course i will not share the room. i have some vga, powercolor rx 470 4gb , saphire nitro rx 470 4gb and 8gb, and rx 480 refference. just asking, your mod is running smoothly in all card ? because each card have diffirent assic stat's Please communicate as much as possible here so others can learn. I will swap ROMS etc by PM. Most of my ROMs are meant for mass use at my farm and run stable. I would recommend letting me get a couple together like the Reference ROMs and let you try it out and see what you think. Give me a day to put that one together. The ROMs I do I typically keep to myself but I am angry about the way people are treated on this forum by others.

I certainly will, Nitro are easy ;D True, they already have standard global VDDC. So if you know how to open a HexEditor and know your way ove rto overclock forum. Then yes, this is easy. It's those that don't have global vddc, those are the interesting roms :) This is indeed childs play :) Also have i been able to add support for multiple memory types: as in 1 rom for both Hynix and Elpida for example + being able to boot headless into windows ;D I wish you good luck and it's nice what you're doing for the community! Greetings! Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: kilo17 on October 21, 2016, 07:32:56 AM Let me clarify, I will help people learn to do their own ROMs. I am not looking to do 100 different ROMs, I don't have that kind of time.
As Eliovp has pointed out they aren't the easiest thing to do and take time to do correctly. If someone wants to help themselves I will help them. Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: dexxa05 on October 21, 2016, 09:15:45 AM Hi,

Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: 64dimensions on October 21, 2016, 12:43:23 PM Would it make any sense to approach this from a different direction and just say XYZ brand 470s and 480s are the "easiest" ROMS to work on?
Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: Tmdz on October 21, 2016, 02:13:59 PM I think sapphire Nitros are the most popular, I have 2 470's coming today.
For the most part running a modded rom is pretty simple stuff the average technician can do. All we do is configure the options and flash the rom to the gpu, then start mining. Now where things get tricky is with that elpida 470 ram on the nitros where PBE will corrupt the rom, so you have to edit it in a hex editor and create check sums.

If you have time to educate me on how to modify my gigabyte 480 bios, that would be great! Thank you :) Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: niksdt101 on October 21, 2016, 07:55:08 PM is the msi 480x card better than sapphire 480 nitro card ??

I am willing to learn how to my rigs using Hexeditor method. So far I hadAs Eliovp has pointed out they aren't the easiest thing to do and take time to do correctly. If someone wants to help themselves I will help them. 3 full rigs of RX480 8GB ref 1 rigs of HIS IceQ RX480 8GB. Link: http://www.hisdigital.com/un/product2-933.shtml They had same heatsink design as XFX RX480 GTR. But not sure about pcb side. 2 rigs of XFX RX480 8Gb GTR. All these cards using Samsung memory chip. So I guess they all had same timing right? So far I manage to using Hex editor, locate the memory timing. I think i can replace the timing. But I dont expert enough to modify the VDDC for these. Willing to learn how to do it. Thank you for sharing your knowledge to the community.

This is not a ROM you just post and flash. These need to be fairly card specific. As explained previously I am willing to help others to learn to make these types of ROM's but unfortunately I cannot just sit around and make ROM's for people. I am willing to help people help themselves.

I thought I would create a thread and help people with ROM's that are like me, less intelligent than the "almighty" ones here on the forum. Hey, i never understood why, after i invited you to ethOS (we were chummy then), all i heard is you threw a fit and asked for a refund. (And you started ignoring me) Then while we discuss stuff in another thread, you come and invade my thread and then create your own, insulting/denouncing people publicly. I would ask you stop twisting things and creating drama out of it. Now, i congratulate you for being willing to take your time to help small users for free, like we have been doing in #ethereumOS for months. It's the support channel for ethereum mining distro, but we spend 99% of our time actually helping people set up their rigs and get the most from their cards, several hours a day, everyday. I'm probably just wasting my time, trying to patch things up, but i had to try. Regarding the voltage offset set in BIOS. Small time users can just use wattmontool or a pletoras of tools to make it happen. There is no need to have them risk bricking their cards. I believe it is only of interest to users whom have a large farm, that can't tweak cards one by one. Using this mod, they will save thousands of dollars (maybe even per month), and you denounce people for asking a little something in return. For example, the last mod i sold, the guy ROI'd from the saving i gave him in 2 weeks. I guess i'm selfish, but if i'm going to save someone 20k USD per year, i'm going to ask for a BTC or something. If you're willing to help them saving that much money without getting something in return, then i applaud you. Actually I complemented you on the ROM in your thread and questioned the cost/benefit ratio. I have no problem with you but it is apparent you are upset. You took my quote and put yourself in it when it was not directed at you at all. Secondly, in regards to Ethos and Kotarius, I participated on the channel helping people and told him that I was running more rigs than I paid for and would send him the money. He said no problem but then later cut me off from accessing my miners and WILL NOT give me access to the 12+ licenses that were paid. Essentially he stole $360 from me. At this point it is a moot point. I am much happier with AwesomeMiner that allows me to control as many rigs as i want, install other miners not supported and allows me to mine whatever coin I want.

As Eliovp has pointed out they aren't the easiest thing to do and take time to do correctly. If someone wants to help themselves I will help them. If VoltageObjectInfo has an initialization table for the VRM, it can be added very quickly. You can automate most of it. Probably easy for a programmer of your caliber but unfortunately my programming stopped with Pascal in the '80's :-\ . I will definitively look into it. Thanks for the idea. Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: bobben2 on October 22, 2016, 04:27:15 PM All,
If you happen to have the Sapphire RX 470 card you can BIOS mod the core voltage quite easily using a hex editor as described below. Possibly, this method can be used on other cards, too. If you mod your BIOS it is at your own risk. I bear no responsibility. I used HxD to undervolt core of my cards. I found a recipe on overclock.net on Polaris Bios Editing - http://www.overclock.net/t/1604567/lightbox/post/25523158/id/2873391 (http://www.overclock.net/t/1604567/lightbox/post/25523158/id/2873391) Open the ROM BIOS file retrieved from your card in HxD. Search for string FF 00 01 07 0C 00. Locate the four bytes just preceeding the above string. If the first two bytes = 8D 00 then the next two bytes is the VDDC. Say you want a -75mV undervolt. Then store the value F4 FF in the two bytes. The actual value is FFF4 hex, which is -12 decimal. (-12 x 6.25 = -75) After edit your BIOS should read: 8D 00 F4 FF FF 00 01 07 0C 00 Save the file and open and save it with Polaris BIOS editor to update the checksum. Then flash your card. After reboot you can verify the lowered voltage using the TPO GPU-Z sofware. Good luck!

It's possible on every other model, but you'll have to add those offsets yourself ;) Which is perfectly possible :) Title: Re: RX-480 - 31+mh @ 125w at the wall - Modded ROM - HELPING OTHERS Post by: kilo17 on October 23, 2016, 02:33:30 AM All, If you happen to have the Sapphire RX 470 card you can BIOS mod the core voltage quite easily using a hex editor as described below.
