Re: [GUIDE][TUTORIAL][XMR,ETH,ETN]How To Mod Bios RX470/570/480/580 VEGA Mining 💰
Can someone PLEASE share modded bios for
XFX RX480 GTR 8GB (samsung)
I cant get it working... my best result is ~28mh/s on ETH and when I try to overclock the memory over 2000, system crashes.
Please HELP!

Never had an asic before.
How often should you restart your Antminer (even if its running fine without issues)? And how often do you shutdown it down and let it cool down for 5-10 mins?

You can skip this step by placing wet towel on top of it once a day
Re: Can't find R9 280 mining bios, no one is mining with it ?
LOL! you MUST flash moded bios to get 320+ sol/s on them. If just overclocked you will get 290sol/s. Bios must be moded by hand to get it working stable (some bioses have 1 or 2 or 3 memory types in them and they can be listed in different orders, so the best way is to modify it by hand) from my 15 280x's this sapphire dual x was the WORST model. Spent days trying to mod it (I was getting system crash every hour). In the end, I left them on stock bios and oc them.
Re: Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b)
on my 7970 I have 298H/s with 1100/1575, and it works without crash
but i can't improve my Sapphire 280x Tri-X OC to this results, I have only 286H/s in stable. What clocks are you used?
p.s. timings are 1250MHz

Strange
I tried to mod bios, but i did not achieve any increase in performance. Maybe you could share your bios domp of 280x? atm i get 245-260h/sFor save you card alive you must edit your stock bios file. Bios from another model of card can make a problem, or even brick card. There is a automatic patch to Tahiti.rom files, but it don't help me, because card pump to +500H/s and almost all shares was rejected)) May be it help you))
I wanted to open your bios dump in Hex Editor, to check memory timings and compare with my moded bios. thank you.

I also have a 7950 in another rig running at 285H/s
If you aren't getting these speeds, hack your memory straps, use 15.12 drivers, use windows 7.
The other 2 slower Tahitis are 1000mhz core clock because they are the crap Gigabyte windforce and overheat easily so I can't run them at 1100mhz, however chances are they would run at 330h/s under 1200mhz.
So the hashrate is clearly linked to engine core clock speed.
However for them to run at 1200Mhz you would need to run at stock voltage or overvolt and your power consumption would be in the Scrypt Litecoin power consumption terrority. I am talking about 300-350Watt per GPU at the wall. Not worth the extra speed boost.
Especially since the Gigabyte Windforce 7950/7970 were known to catch fire during the litecoin days.

Even at 1100 your crazy...that must be what in the 250 watt territory? I run my Tahiti's at 975 to keep them under 160 watts @ 270s/s. Don't think the extra 10-20S are worth the 50-100 watts per card.
At 1100 it uses 200 watt only because you can still undervolt them.
can you share your 280x bios dump?
