Hi all,

I’m having trouble figuring out why my sapphire pulse 5700 xt is failing to flash/read rom. Weirdly, I was able to flash 8 of the same cards successfully. I tried to flash 1 more and both times gave me the error above.l.

I’ve tried:

-DDU to uninstall and reinstall drivers
-Connecting the GPU directly to mobo’s x16 slot
-Using different risers
-Using atiflash293plus
-Using atiflash normal
-Using  -AtiFlash -unlockrom 0 -Leaving only 1 GPU plugged in -Using different file paths for AtiFlash folder
- clean install windows 10
I’m not sure what do to at this point, anyone have any ideas?

my results

this is true? seen on reddit, users say it works and that by adding an 8gb ram gpu as the main one, you can generate the DAG and continue mining with 4gb cards

Recently realized in my farm that my 470 4Gb rigs, which were all 6 card setups at the time, were not generating the dag any longer for ETC and then soon after ETH dag approached whatever level it was that pushed my system over the limit. After a day of wondering what to do, I realized a 470 rig I have with 1 8Gb 580 in it was working fine with the other 5 cards being 470 4Gbs. I took apart one of my 580 8Gb rigs and replaced a card on one of the 470 rigs. Mined perfectly fine. Did this to the whole farm and split the gpus essentially so every 4Gb rig has atleast 1 8Gb card in it. As for now this works no issues. I have a p104-100 rig with 1 470 4Gb in it and same thing, generated dag and mines.

I tested this on 2Gb R7 200 gpus and works perfectly fine. Card generates the dag as long as the system has one available card that is able to fit the dag on it. This is identical to how the 470 rigs are operating.

The same goes for 470 4Gbs with rx 5700s.


Edit:
I  tried and  works. display GPU 580 8GB, others 4GB mining eth classic windows 10 claymore and phoneix without any problem



What kind of sorcery is this?

Memory 950
core clock 1200

Ethereum hashrate 26.5-26

power 70W-65w


I need more time for the tests. but it seems that the performance is not very good. maybe with some custom timmings ...

I expected more performance, maybe with some custom timmings I would improve a lot. at the moment the Navi bios cannot be modified.

remember that a rx 580 stock reaches 25mhs with custom memory timmings can reach 31mhs

I want to assemble new mining rig, the question I have is use the new radeon RX 5700 or the new nvidia 1660 super.
Nvidia is cheaper and consumes less power but has less hashrate. RX 5700 is more powerful but consumes more. And resale is worse.

Or maybe wait for the new RX 5500 or other series?


would be for ethereum mining  sorry for my bad english.

It would be interesting to see the hasrates and the power consumption of this gpu

Finally I bought gtx 1660 non TI. These are the results, Not bad for the price and the lower power.




less power only 69w

hashrates needed  

I read in this forum, there was a program similar to watttool but it worked perfect with the rx 500 series, but I can not find the thread, even I was on the author's page to download it.

Someone knows the program I'm talking about.? thanks

Sabéis alguna tienda online donde vendan mineros preferiblemente en europa o en España ya que me pongo, de momento solo he visto ebay aunque todo lo que venden me parece caro (S5 a 400€ tamos locos?)

fuera de eu paso de comprar tengo la suerte de que todo lo que compro me lo paran en aduanas

Buenas, busco Antminer S7 preferiblemente con fuente de alimentación.

Looking for two antminer S7 with PSU in Europe, Im from Spain.

PayPal payment only, reliable sellers with good reputation.

I value photos, date of purchase, batches, temps.

Thanks
