Hi Guys,
Here is a very strange problem.
I have a bunch of MSI RX470 ARMOR 4G cards, I bought them about a year ago, all came with samsung memory.
All works fine hashing 28+Mh/s on ETH+DCR. However fans started to die on couple of cards. So I sent them back to MSI.
Instead of replacing the fan they sent me an another card(serial number is not the same).
Also came with samsung memory, the first thing that I noticed is the different bios.
original one: 113-V34121-F1
replacement one: 113-V34121-X2
So I did the same 1750 strap change in this "X2 bios" as well, however these cards don't want to hash with more than 24Mh/s
I tried the 1500 timing too, no matter what I do, the maximum hashrate that I get is 24Mh/s.
I have 3 cards like this.
What is different on these cards?
Have you seen something like this before?
Any idea?
Thanks in advance,
