XFX Dual BIOS Mining

Equipped for gaming and mining

We know enthusiast like options, our RX 570 and 580 graphics cards are shipped with a Dual BIOS. If you want optimal gaming performance just install it and go. For cryptocurrency mining, simply shut the system down and flip the BIOS switch on the card. Our mining BIOS is already tuned to give increased mining hashrates without hassle.

i grabbed a few gtrs this week alrrady flashed them but this sounds interesting to me anyone try those bioses?
or even know what cards have this?

Hmm, I have not read about that anywhere yet, but it sounds very appealing. No more risk of bricking your card and worrying about invalidating the warranty if it comes bios flashed/tweaked right from the manufacturer.

I have a bunch. While I haven't actually pulled the rom, the only thing I've seen it do is change the core clock
It does NOT change the timing straps or memory speed

That's pretty useless then if that's all it does. I figured it would at least be a simple strap copy and memory clock boost.

Waiting for tests from owner's.
But i am think peoples not trust the manufacturer and tweak bios manually. minimum I would check dump

I have my own Bios mod for these cards , but i cant get to the garage to check the bios switch till tomroow, ill have more info then on the bios

with my own rom i do 2135 mem and 1114 core , voltage and mem settings do not seem to take so i overdriven for those.

I have to say these are the easiest cards to mod , one mod works for EVERY card zero exceptions, i have around 10 of them 3 new ones added yesterday before i found this thing about the custom mining rom
I'll test tomrow.

If i could buy these cards in bulk i would because they are the absolute best Polaris cards out there.  They run stupid cool and half the time the fans don't even need to spin even dual mining
30mhs and 1100 DC or 90 lbr all at a wattage of 120 watts , basically comparable to a 1070 wattage wise.

One thing I don't understand is why they have a six pin and an an 8 pin power conector and unlike other cards you HAVE to connect both or the damn things wont work.

Only best buy seems to sell them atm and they are overpriced there $399 LOOOL , anyone have another source for these cards ? I'd really like to standardize on them regardless if the bios thing is BS or not

I think they could easily do 2200 mem but i like to have 1 rom for every brand of card and not have to fine tune each freaking card, I already have 20 rigs

I am fully agree with this position, and i think is better option for full stability of rig
