I just control the voltage controller directly through i2c command, also added the offsets directed to the BIOS for a more permanent solution.

Ok I lied, thats not the best card...check out this one I just got in (GPU1 in Claymore)...100 watts at the wall on a -275mv offset!!!

I guess these really do have way better silicon.

Where have you guys been?? They have already added over 2000GH to the network in a span of a month, and don't seem to be stopping until they milk this cow dry. I wouldn't expect them to stop until the ROI on these things are in the 10-12 month range. So at current prices were looking at a network hashrate of 15 TH by the end of the year.

60c @ 55%

There is no reason to go with a 8GB card for eth mining. It will perform exactly the same (there are variances between different memory types but thats about it). Eth will also be POS by the time the 4GB limit is reached.

I don't see any scenario where a vega card can beat out a 570.

2x570 = ~60 MH / 280 watts / $340

High end Vega w/ HBM 2 = ~40-50 MH / ~250 watts / ~$500-600

Low end Vega w/ GDDR5/x = ~30-40 MH / ~200 watts / ~400-500

The only way I see the low end vega outdoing the 570 is if it under-clocks/volts really well, and you can fit two of these cards in the same power envelope as 2x570, and be able to kick out about 80 MH using < 300 watts. If they go aggressive on pricing and its under $400 per card then that would make sense.

Your doing something wrong, I have this card at 29.5 MH @ 130 watts. Definitely the best bang for buck for the current 500 series line.

It won't be compatable with any current off the shelf MB, it's just a switch (like the 3 port one that's been around forever...this just has 8 ). I was thinking of going this route with my 16 gpu solution, but the switch aspect is only half the story. You need a motherboard that can actually handle more than 6-8 GPUs

So beware if you think you can buy this and magically post more than 8 GPUs on off the shelf current gen mothboards most of you use for GPU mining.

No I bought a few in the May batch, but the April guys should have been shipped out by now, since they are supposedly paying out daily till delivery.

Anyone in the April Batch get word of whats going on yet? They still having "firmware" issues even though they have already chipped out 1.5 TH worth of miners to their chinese pools?

Never understood why people buy the 480/580 for a $100 premium when you can pick up the 470/570 for 170-180 and it hashes the same.

^this....no one is denying that Bitmain are not cocksuckers. They have been playing everyone since the start...their own customers, the markets, and even Charlie if they don't end up signaling in the next 24 hours...

Looks like the May batch was quite the Deal if they ever decide to ship them out.

The BIOS just contains memory straps for both Hynix and Elpida memory.

I hacked together a prototype tank for some testing a while back. This is just a simple open loop design (just runs and dumps cold water through the coil). Have some more ASICs coming so maybe ill modify this with a real closed loop design.

I PMed you.

Anyone who bought these miners from them should be screaming bloody murder. He is using your money and machines to destroy the coin and your profits all for a personal vendetta.

Ive been in crypto for a while, and have seen my share of disgusting behavior...but this has to be near the top.

Except you wont have polarisbioseditor to do it Better start learning how to do it by hand.

They already have, its called LTC1BTC. This is why the only non segwit signaling pools are Antpool and LTC1BTC...

Based on my estimated size per chip, they are probably producing 100k chips per wafer batch. So about 300-500 units per batch. This is inline with the first L3 batch that bumped hashrate up by about 200-300 GH. To be safe figure they are producing 500 per batch, for a total of 1,500 units for the 3 batches. Your looking at least 750 GH of hashrate added to network. So at least 3.5 TH by July. I would base any ROI calculations on that.

And of course you can assume they'll do what they did with the L3 buyers that got screwed...sell double the hashrate miner for half the cost in july again
