What is the best GPU to mine XMR today(H/W)?

Hello guys
I have a problem when I mining monero  with amended bios

but When I do return to normal BIOS works well
I want to help solve this problem

Most likely something like Polaris Bios Editor. This allows you to load your GPU's bios setting and modifying. The "Strap-1500" method that people talk about is copying the long string of numbers under 1500 timing and pasting them over the existing values for the higher speeds then saving that nd flashing your GPUs with it.  BUT... timings are only 1 field of many in this bios editor, so yes, he has likely made changes to other fields to achieve the extra speed.

The other thing to be aware of is that mining is not 100% about speed.  Most smart miners work to achieve the best possible speed per watt ratio. There may be some exceptions to this but for the most part, you will make more profit by fine-tuning your rigs to get the best ratio, which won't necessarily be the highest speed.

Furthermore... yes, when you hear someone talk about a "custom mod" and they don't volunteer any further info, then it is very likely that they simply don't feel like sharing what likely took them many hours to figure out for free. Nothing wrong with this IMO but you will find others in this forum who don't mind sharing their settings and such.  Bottom line, you can drive yourself crazy trying to match the speed of others. There are so many factors involved and sometimes you can have the exact same hardware and setting but still not match someone elses speed (maybe you got a bad batch of GPUs or they got an exceptionally good one, etc, etc).

My recommendation would be to mod your cards with the well-known/tested method first and that will get you most of the way there.  If you have the gumption, you can play around with settings, bios, etc but be forewarned that it can cause tons of downtime and messing with bios could brick your card, especially if you are experimenting.  You have to ask yourself if it's worth it.  If you are already getting like 700 and maybe could get to 750 but trying to get there causes days of downtime and possibly bricks 1 or more of your GPUs, you could make a very good argument that the extra 50 likely isn't worth it.  But of course, everyone has their own thresshold for things like this, so good luck with yours .

I have the same problem

Download official wallet here:
https://getmonero.org/downloads/

Or use the beta GUI:
https://getmonero.org/2016/12/22/monero-core-gui-beta-released.html

on dwarfpool i keep getting json rpc error 2.0 lowe difficulty share anyone else seen that ?

How to get monero wallet? poleniex or monero.org?

Thanks Claymore for next great miner    Getting 1600 HS with 7990+7950, just wanted to ask you guys what setting are you using for gpu mining in msi afterburner or whatever you are using coz I heard somewhere that it's better to use bigger power limit + voltage for monero mining... Is that true? Thanks

I have a r9 fury (-800 h/s) and r9 290 (-700 h/s) but the combined speed of both when the miner reports in blue text is only 1383. Is that correct? Also it seems like the default hashcount for the fury is a bit high? My fury is using almost all 4 gb of ram it has. Whats the optimal hashcount setting for a r9 fury?

thanks!

How undervolt the card at bat file
What I must write for undervolt -90 mv

This is my 380 bat file:


I would change the clock and mem to 1050/1500 for 280x.

This is something I am quite familiar with.  When I was mining ZCash I modded all my 280x's and 380's.  The mods performed as expected as discussed in the https://bitcointalksearch.org/topic/hacked-modified-memory-strap-bios-database-for-zec-mining-1676474 Hacked Memory Mod thread.

I didn't bother to put them back to stock then started using this miner with those same mods, some of the cards performed in low 600's with 1050/1500 undervolted to 1100-1125, others were in the upper 400's range, most averaged around 570.  I re-modded those under-performing cards and now they perform like the others.  I have no idea why.  Needless to say, I believe that the optimal memory timing for Tahiti and this algorithm have yet to be disclosed.  Ask Wolf0 if he agrees.  

what i must write at bat file
for mining minero?

Claymore
Please make new miner for linux for AMDgpu-pro

Thank u. Do u mean he used hex editor? What really does modifying mean? How would it affect performance?

Please tell me afterwards miner vyklyuchaetsya! you need to create one? thanks to all

Given the price of XMR it is time for a new miner!!!

I'm mining with 2% in dwarf.

It was higher, now it's 2.5%

dwarf pool says the fee on this miner is 5%  is that right ?!
