High Sierra on cMP (4,1 flashed to 5,1)

this explains how the GPU apple includes in the eGPU Box shows up with its proper name in High Sierra 🙂

its quite interesting how they do it, its good to see that the RX480 and RX580 have a proper frame buffer, its been a long time since Apple have given us a Frame buffer that matched/was meant for a normal PCIe GPU

This is exciting news, I wonder how this will translate to our cMP's

So it sounds promising that a Sapphire AMD RX 580 PULSE will work via a 2 x 6-pin to 1 x 8-pin adaptor in the cMP once High Sierra is released using the built in drivers without kext mods etc. ?

its looking pretty damn good 🙂

the way the card acts is interesting, its half way between a normal un flashed PC card and a fully flashed Mac card, not something seen before, might open some fun doors in the future to fun things 🙂 will be interesting to see what the gurus ( @netkas @Fl0r!an etc) can do with this stuff 🙂

The worst case is they will expand and continue to buy graphic cards on a massive scale, as each cards generates $, if there will be no mid-term Ethereum crash.

Doubled in the last week. Peaked at $400 and crashed to $330 today. Currently back up to $380. That's highly volatile. Bitcoin lost 20% in the last two days.

This isn't a stock, it isn't based on a real world commodity or product. Be careful what you pin your hopes too. I say that as someone wth Eth and two small miners.

The best time for mining was last year when you could earn 1 ether in a day with just one GPU. Now you need two good GPUs to earn an ether in a month. The difficulty keeps increasing and nobody knows if this will pay off or it's a scam.

I would feel very sorry for the people who are running out to buy many very overpriced AMD cards (and also the rig to install them in) and then quite possible never make their investment back.

In fact because these AMD cards are now overpriced on the used market, the best card you can get for the same price is GTX 1070. I configured two of them to pull 62MH/s at only 100w per card. Nothing AMD touches that.

Whoever has the dev kit, can you fire up that card in a windows box and use gpu-z to backup the firmware and post it here? Getting an efi rom up should be too difficult from there. I'd imagine it will be very similar to the 7950/280 rom builds...

Ps I checked today and eth was around 391.00 today. Still profitable to mine. And I've got 6 amd cards laying around I can mine with to make some spare money. And eth isn't the only profitable coin to mine ATM...
 
I have a supply of AMD Polaris and 2xx series. I'm going to unleash them on eBay at great prices so I can crash the people who are

you don't need to be netkas to do it
he explained somewhere about how to add the crc32 of 4,1 firmware into the 5,1 updater.efi

If I recall correct it's not his patch anyway. Someone posted it in his forum.
 
Guess I picked the wrong time to buy a flashed gtx970. Any word on Nvidia support for Metal2? Or are they going to stick with CUDA?

Also here's hoping APFS works with spinny drives, I just bought a 2TB internal drive as well.
 
Someone's selling an RX580 4GB on eBay for £700... RX480 going for £350... R9 280X for up to £150.

Edit: Oops wrong thread, but you guys can enjoy the information too!

Interesting, I can easily buy a RX580 8GB below $300. Who will pay £700 for that? It's the current generation GPU, available everywhere.

In my home town, Hong Kong. We can always easily get the most up to date stuff. However, little bit hard to get the one generation old stuff. And extremely hard to get anything 2 generation old from the local computer store.

I didn't realise this card is out of stock on the internet, because it's wildly available on the physical store, I didn't check the online availability.

May be I should buy them and then sell them on the net 😛

Off Topic a bit, but can someone explain to me what this 'mining' thing is all about?
I have googled it, but am baffled by the results.
This is the first time i've heard of it in this thread.

Pretty sure he was talking about bitcone mining.
 
It's when you make your computer crack a puzzle to get a reward. The reward is a token that some people trade for goods or money. Essentially it's video game money. People traded digital tokens and assets for real money for many years.

Mining ether will be finished by next year. Mining is horrible for the environment and it means those who invest in large scale mining obtain monopolies.

Mining Bitcoin is pointless without large ASIC farm. It had a head start but it will soon end up in a death spin.

There are small coins that will still have miners but 99% of them are scams designed to drain money out of other people.

The value of these digital assets are very volatile because they aren't rooted in real world economics. There's no regulation. It's like the Wild West and speculators and scammers jump on it.
