Use -cclock and -mclock, check FAQ of Claymore miner for more information.

If I had the card in front of me I would keep going even if that ment I had to start digging into hex. However I had to put together a separate machine running 16.11.5 to flash some of my samsung memory cards then when put back into a system running 16.9.2 they worked perfectly. Side note if none of them work your not out anything however if they work and you chose to send me a tip that would be cool.

Hynix won't be stable over 1950 MHz with the common timkng straps. Even with custom straps you are lucky if you can go over 2000 Mhz. 1950Mhz with 1500 timing should bring you about 28 mh/s.

You won't need any wattool,wattman,afterbuner,trixx or any other software of that type, i set everything in the bios like Insider00 did with wattool, so : Def gpu clock : 1144 Mhz Def mem clock: 2150 Mhz Mem straps 1625 VDDC (gpu voltage) set at 925mV TDP 120w Set fans to hold cards at about 70c, so you don't need fan regulation either Before flashing remove ALL software that you used before for manipulating (wattool,wattman,afterbuner,trixx...).

Hynix won't be stable over 1950 MHz with the common timkng straps. Even with custom straps you are lucky if you can go over 2000 Mhz. 1950Mhz with 1500 timing should bring you about 28 mh/s. yeah my hynix 480 and 470 cards i just used 1900-1925 some even as low as 1850 just to keep them stable my feeling is 1 or 2mhs more hash is not worth me rebooting a rgig once everyday Title: Re: BIOS and mods for Sapphire RX 480 8gb Micron Memory - 0.25 ETH reward for help Post by: GPUM1ner on May 01, 2017, 06:29:05 AM Thanks doktor83!
Your rom allowed 4x Sapphire Nitro 480 8GB reach 29.3MH/s (Micron). I tweaked the settings a bit, but I mostly needed the straps as PBE wouldn't work. 1100 GPU/1000 mV 2050 Memory/1000 mV Fan minimum 50% makes them run smooth. I can't confirm his rom is best, but at least the straps are changed. What strap mod did you perform?

First of all, thanks for the BIOS Doktor83. I have a strange issue: Doktor83's bios has the temp settings: med temp - 45 high temp - 56 max temp - 73 And in MSI Afterburner i can see the max temp limit is 65. Of course after my cards reach 65c - reboot. But the original bios: med temp - 65, high temp - 85 max temp - 109 AS for me, that is some kind of bug. Any suggestions ? Should i change the temp settings via POlaris and than flash the cards again? Thanks!

i have Sapphire RX 480 8GB Micron (NON PLUS) It is better to copy the 1500 strap or a other one? what is the diffrent and what is the best bios mod for my card? Update: i have this night moded the bios and set Mem: 1160 Powerstage: 3 Memory: 2150 and get 29,4 mhs :-) Link: http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-480-8gb-oc-micron-memory-30-mhs/ Regards Willi Title: Re: BIOS and mods for Sapphire RX 480 8gb Micron Memory - 0.25 ETH reward for help Post by: Vaas on June 03, 2017, 06:52:03 PM For all of you guys i made a custom bios from the one in the main post. You won't need any wattool,wattman,afterbuner,trixx or any other software of that type, i set everything in the bios like Insider00 did with wattool, so : Def gpu clock : 1144 Mhz Def mem clock: 2150 Mhz Mem straps 1625 VDDC (gpu voltage) set at 925mV TDP 120w Set fans to hold cards at about 70c, so you don't need fan regulation either Before flashing remove ALL software that you used before for manipulating (wattool,wattman,afterbuner,trixx...). Then clean all video drivers with DDU. Flash bios. Reboot, reinstall video drivers. Test. Enjoy ;) http://www.filedropper.com/s480-8gb-micron (http://www.filedropper.com/s480-8gb-micron) worked great but my 480 nitro still keeps the fan at 0% any insight in what might be happening? also the newest driver didn't recognize it, can the ATI pixel clock patcher solve this or not??

A little help needed here :) My card is an ASUS RX470 STRIX GAMING 8GB OC with micron memory, and I'm doing dual mining ETH+DCR with claymore. And using afterburner for tuning. I tried a lot of variations but my best was 25MH/s ETH + 780 DCR. (or 26MH/s single) drivers: 16.9.1, 16.9.2, 17.5.2 gpu: 1000, 1025, 1040, 1050, 1100, 1150, 1200, 1250 mem: 1750+ straps: 1500, 1625, 1750 At the moment I'm mining with 16.9.2, 1100gpu, 1900mem, 1750 straps (this seems stabile and the best so far) Highest was 28.5MH/s with 17.5.2, 1200gpu, 2100mem, 1750straps, but GPU failed over and over again. Also tried WattTool, and copied the settings Insider posted, but could not get better result at all, and most times my pc crashed. There you go :) Follow this steps in screenshots -Wattool Setting http://prnt.sc/ep7nfg , http://prnt.sc/ep7ly0 MODDED BIOS : https://www.dropbox.com/s/p87dtcrv5yh733u/m.rom?dl=0 Wattool download ( http://www.overclock.net/t/1609782/watttool-a-simple-tool-that-combines-overclocking-with-vrm-monitoring-tweaking-for-rx-400-series ) This u will have to keep in start.bat Wattool commands to write in start.bat TIMEOUT 2 start WattTool-0.92.exe 1 2 3 4 5 6 TIMEOUT 5 I have sent everything to BuriedONE Blockchain Youtube channel, he will make video for it soon Good luck :) My goal would be 28-30MH/s if possible.

PM, me. Title: Re: BIOS and mods for Sapphire RX 480 8gb Micron Memory - 0.25 ETH reward for help Post by: Intellion on June 08, 2017, 08:55:17 PM Guys, I'm in search of advice. I have a Sapphire Nitro rx480 card (non plus model, Micron memory) 11260-20-20G. All the modded ROMs I've ever tried make the Claymore's miner work for about a minute or two at 30+Mh/s before crashing the Windows 10. The recent one from this thread (thank you, doktor83!) worked for about 15 minutes at 29-30Mh/s before crashing the drivers and rebooting. So, can't make it work in stable mode.
I also have a strange problem - the Watttool 0.92 doesn't show anything for my card, everything is zero. Also, neither Trixx nor the GPU-Z show the GPU temp. The latest version of Windows 10 with Crimson 16.9.1 drivers (newer drivers do not recognize the card with the custom bios for some reason). Also, what is the reason that some of the modded ROMs are 256KB when the original ROM dump is 512KB? I need to know if it is the problem with the card or I'm doing something wrong. The card is hashing at 25Mhs on default ROM (see the link below for the original ROM). http://wikisend.com/download/708788/RX4808GBOCnonplusOriginal.rom Title: Re: BIOS and mods for Sapphire RX 480 8gb Micron Memory - 0.25 ETH reward for help Post by: Mattthev on June 09, 2017, 10:39:49 AM Guys, I'm in search of advice.

I don't know what's going on with my GPU, maybe the room temperature for our place is too hot, It's very unstable to run at 2150mhz for me. but solid stable at 2000mhz. ------- Update: I got it limits @ 2000mhz by using PolarisEditor for micron memory from this website. http://forum.ethereum.org/discussion/11855/rx480-micron-memory-not-the-worst Title: Re: BIOS and mods for Sapphire RX 480 8gb Micron Memory - 0.25 ETH reward for help Post by: AlainC on June 21, 2017, 06:12:27 PM It is hot weather in france and I have prepared dozens of bios with 10MHz steps, and 5W TBP/Maxpower, and my miner got few memory errors, and stepped back to 40MHz less, or to 10W less in TBP/MaxPower... it is happy now.

If I had the card in front of me I would keep going even if that ment I had to start digging into hex. However I had to put together a separate machine running 16.11.5 to flash some of my samsung memory cards then when put back into a system running 16.9.2 they worked perfectly. Side note if none of them work your not out anything however if they work and you chose to send me a tip that would be cool.
