I am running 144 sapphire rx 470 8g and rx 480 8g cards and have been since Christmas. I have lost 5 cards in that time mostly due to running them too hard. I have backed down on my DCR production to reduce total amp load on the cards and have not lost any in the past month. If you have a rash of failures it is most likely due to a power spike or a variable power feeding your system and not a single power supply or set of risers, although cheap risers can fail at an alarming rate. The nice thing is that even though my cards run a mod'd bios the manufacture has replaced every one without question, so I continue to stick with Sapphire and I am expecting my first batch of rx 570 8g cards tomorrow to see how they perform. Has anyone had any experience with the new cards that they can share in regards to performance differences and set up changes from the rx 470 8g cards they have?
Hi people, first sorry for my bad english, my problem is that i buy 4 saphire nitro (no plus) RX480 8GB, and i think i did a very bad buy becouse this model
https://www.amazon.com/gp/product/B06VSWDK2H/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 it has only 1750 mhz of memory clock and i think that it dosent have doble bios option. I buyed becouse i did not know that there where 3 diferents models of nitros... my question is, how much less hashrate will i have with claymores miner? and does standart bios mod for nitro+ work in this version or do i need a different one?
PD: I read that peoples gpus are dying for using dual miner ether/+ and for mod the bios, i do not want to happen to me, does it really damaged your card to mod the bios and do dual coin mine?
- Its not a BAD card. Its is a cheap card. This is why you chose it in the first place. So you already saved some money. Why regret now?
- You still can mod Bios. But modify it yourself rather than use someonelse's. Follow step by step instructions bit by bit (can be easily found via google).
- You should ask questions on the forums where you read "that peoples gpus are dying for using dual miner". I did not see anything like that in this thread.
I bought 6 of these cards because I did not notice they were not Nitro+ cards, and I could not return them once I got them, so I run them at 24 MH/s on ETH and 1000 MH/s on DCR. Have you found a good way to mod them to get more, because everything I tried just made these pieces of crap trip out? So I use Claymore's program to adjust the voltage and clocks down and get what I can until the cards die. I would love to find a set up that is stable and delivers better performance.
