Ethereum 30% hashrate drop for RX400/RX500 incoming soon?

[jpoker272727]

The Claymore benchmarks figures show a progressive gradual drop of up to 25% through epoch 160, which I found to be overstated compared to the actual epoch drop. Even if not fixed, adding a single $220 RX 570 4GB card can offset most of that drop. There are also indications from one of AMD's lead developers that the issue does not affect SGminer in Linux with OpenCL 2.0.

Thanks for sharing these detailed change with the latest EPOCH, but how often does the epoch change?

When will we see epoch 140,150,160?

I see there is a drop also in the dual mining mode, from your stats there is a drop from 2-3 MH/s in DCR.

P.S is DCR more profitable than SC? Can you share your configuration please, I'm using -dcri 16 and is not affecting the ETH hash rate, or dcr is more profitable than sia?

Is this JUST with claymores miner? I saw the BBT video but read through the thread, are other miners not affected by this?

Be interesting to see if Claymore is actually speaking with AMD.

Also, with the new AMD cards coming out, to see if it affects them too(because I have 30 of them on order).

Like it explains in the video, the epoch changes about every five days and by the end of the year we will be in the 160's epoch. The DCR dual mining hashrate drop was about 0.4% as well. I use -ethi 8 and -dcri 25 for DCR with a core clock of 1150 MHz and a memory clock of 1975-2075 MHz depending on the card. I don't mine SIA, so I don't know if it's currently more profitable. You can check which coin is more profitable to dual mine with the whattomine ETH calculators.

There are conflicting reports as to whether SGminer is also affected. Part of the problem is AFAIK, you can't benchmark future epoch's with SGminer like you can with Claymore's miner. Claymore has confirmed he is talking with AMD about the issue.

Ahh nice one, thanks for the link.

Well if it doesn't get resolved, then it doesn't get resolved. I'd like to know for future reference, if anyone else is having the problem on another mining platform?

We are Nvidia/AMD 50/50 mine, so won't hurt us too much, but would like to know sooner rather than later so can go Nvidia route instead

You can benchmark future EPOCH just by switching mining between ETC and ETH which are on different epochs.

For everybody freaking out, who cares about the 0.4% drop when in 5 days we had a 7% difficulty gain.

We are all on borrowed time when it comes to mining so lets just enjoy it while it lasts, all our GPUs are already paid off and then some.

Guys I have preordered 7x570 4gb which will be shipped 10th of July should I just cancel and switch to gtx 1060?

Yeah, cancel and get the 1070 instead. Even if you can only get 5-6 of them instead go the 1070 way

Anyway, don't believe AMD care about hashdrop at all, even less that they work with claymore for resolving this.

now that amd has miner edition cards i think they would want to fix this. otherwise they are handing nvidia customers as nvida has ming cards also.

See that is the thing, did they fix on tonga up to r9 280x? no, dont expect amd do much here, perhaps tonga and polaris arch make this happen, this flaw is by design, maybe there is nothing amd can do, although the mining community is larger than before, which means they might do something about it if only there is something really to do.

... well said.

Vatalik welcomes you in the ICE-AGE at about mid. JAN 2018.

@adaseb - when do you start waving PASL instead of Furtune-Jack FLAG ?

Why even bother with these cards. They will release Vega and Polaris 20 soon.

How soon until the mining specific cards come out for AMD and Nvidia?

[LoneRangir]

Is this affecting EXP and ETC with the same rate of impact?

[Metroid]

They have been for a while in few countries, even newegg was selling some rx 470 mining specific cards.

Mining cards do not help much with a POS coin. ice age will kill eth mining regardless of the card. So for eth all these new cards are not worth the investment. All current gpus switching tot other coins will kill these other coins as wel. Overcapacity. Only ppl with free electricity will survive

found this: Ethereum mining: hashrate drop for Radeon RX400/RX500 GPUs incoming
Only RX cards are affected, not the older ones like 290x. Also Nvidia Pascal seems to be on the safe side...

why the f is that the case that only RX series cards are affected, this is crap i tell u

Hmm... Looks like this issue indeed affects ETC, too

Yeah. The ice age is for the entire ethereum mining community. I too dont understand all this crap against AMD's RX series. More likely, it will depend on the memory of cards, 4GB cards will soon be too low to handle DAG.

Correct about iceage incorrect about the memory. It's not the amount of memory but the memory architecture and how it is addressed by the miner software. Still unclear about all statements being made.

We will never see a DAG bigger than 4GB in ETH PoW world. DAG increases by a factor of 0.73 per year.
