Ethereum GPU mining?

[Madpacket]

claymore cryptonight vers 10.2 is out. I'm getting 1000H/s per vega64 with 17.9.3 drivers, stock settings.

Nice. What's with all this chatter of the Vega 56's hitting 1800H/s mining XMR? Anyone mining Monero and can confirm their Vega numbers? Something to do with XMR-Stack-AMD....

Starting to look like we need a Monero mining thread.

i think rumor is wolf0 in the bitcointalk folder does, but he's not releasing his code.

Honestly, i think these threads should be in the the distributed computing forum. it's were a lot of us older anandtech members started from.

 

[DrMrLordX]

DC crowd hates mining though. It's a corruption of their hobby. I don't blame them.

We could start an XMR thread though. We have a ZEC thread kicking around here somewhere . . .

sounds good to me. ive been off eth for a few weeks now, its xmr on amd and zcash on nvidia.

What happens if a Bitcoin transaction doesn't get enough confirmations? Does the transaction revert the bitcoin back to sender, or does it go into a sort of limbo?

And can this happen, if you put in too low of a transaction fee?

I tried transferring the bitcoin balance from my PC's wallet, to coinbase, and I first put the exact amount of bitcoin, then it said that the transaction fee was a minimum of 0.00000xyz, so I had to subtract that from the total amount, and then send.

It seems to have sent it, but it's showing 0/unconfirmed. Coinbase says it's "Pending".

Did I screw up by making the transaction fee too small?

 

[thilanliyan]

It takes longer with a smaller transaction fee I think.

 

[VirtualLarry]

But it's going to eventually transact, right? It's been three hours.

Edit: Now I read the *correct* tooltip...

I'm using the official "Bitcoin Core" client, on a Windows 10 PC.

Anyways, it warns that paying the minimum, may result in a NEVER CONFIRMING TRANSACTION, if there is more demand for transactions on the network than...(something something).

Seems like kind of a bug in bitcoin.

I thought that the idea was to be able to send money without fees from middlemen, credit-card processors, etc., but now I get the impression that the network just doesn't run unless you sort of "Grease the skids", like slipping the bellboy a $20 when you check in every time.

I didn't think a transaction fee was necessary, as I was sending bitcoin from myself to my other account.

Where and who do these transaction fees go to? As block rewards, added up between the transactions recorded in a block, to those people hashing? Is that how mining continues, even as difficulty goes up?

I don't pretend to fully understand this stuff.

Edit: If this is a scheduler / queue-theory problem, look at how the Windows NT scheduler handles low-priority background tasks... every so many seconds, they get a basically guaranteed scheduler quantum, and their priority is temporarily boosted. I foresee the need for something like that for Bitcoin, so that transaction processes don't get semi-permanently "stuck", when the system is under high load. Just like those processes would be, if they didn't get any compute time at all, because the system was never truly quiescent.

(Incidentally, this particular aspect of the NT default scheduler, is why I believe that dual-cores, and now quad-cores, that eat a full 100% of CPU time during gaming, will "stutter" every few seconds, because the background tasks get to run, and interrupt and cause latency to the game threads.)

Yes. It can take a while depending on how busy the network is, but it should go through. It's not uncommon for it to take a few hours on bitcoin.

 

[DrMrLordX]

Bitcoin had a lot of lingering unconfirmed transactions that were piling up before the segwit hardfork. Not sure how many of those they have left now. It was a growing problem.

 

[[DHT]Osiris]

They can also take a pretty long time even under the best circumstances. If I'm transferring BTC from Coinbase to Steam (I do semi-regularly) it can often take multiple hours, like 6+. It's a flaw/shortcoming in BTC itself.

 

[VirtualLarry]

been 12 hours, still 0 confirmations, and the transaction hash, can't be found on blockchain explorer sites

Edit: Got up today, went to appt., came back home... FINALLY, nearly 20 hours later, the transaction seems to have confirmed.

if a transaction does not confirm in a certain amount of time (forgot what that was, it varies, basically it falls out of all nodes mempool after a while) it will just wind up back in the sending wallet.

Are bios-modded gpus still stable for gaming?

Are bios-modded gpus still stable for gaming?

Depends on what was done in the particular bios mod, but typically the answer is no.

 

[DrMrLordX]

I had a BIOS-modded 390 that was unsuitable even for simple display duty. It worked after I flashed it back though.

 

[Chicken76]

Depends on what was done in the particular bios mod, but typically the answer is no.

I was thinking of replacing the memory timings for the top frequency with the ones from the second-from-the-top. (like using the 1750 MHz timings for 2000 MHz on 8GB Polaris cards with "8000MHz" Samsung RAM)

yeah if all you do is bios mod the 2000 memory timings (on polaris) and leave everything else stock, you can game at stock memory clocks as they are unchanged and mine at the 2000 clocks. but some mining bios mods go all out, core and memory timing and voltage changes, those give great power savings/increased hash and such for mining but gaming is hit and miss.

if you have a dual bios card you can change one for mining and keep the other stock. just hit the switch and reboot. bit of a pain though.

Would you say there's a good chance the card will be stable while gaming at 2000 with the 1750 timings? And if not, would a small bump in memory voltage make it stable?

unsure. only way to find out with certainly is to try it and see a bit of a memory voltage bump might help but i dont mess with raising memory voltage on video cards as i worry about memory cooling.

Bitcoin's Price is amazing

Bitcoin's Price is amazing

No kidding, I've been watching it since this morning, curious as to whether or not I should sell some of my mining proceeds or HODL more =|

 

[DrMrLordX]

Everyone wants that free Bitcoin Gold. I can't see this going well though. They can't just relive Bitcoin Cash over and over again.

 

[DrMrLordX]

Difficulty has spiked like a sonofabitch. Is that related to the upcoming hardfork somehow? Despite the ETH rise today, my profits are in the toilet as indexed in USD. Only reason to keep mining now is to reap the rewards of upward price movement.

Nicehash has been holding roughly steady over the last 2-4mo, maybe a 10-20% drop in profits, give or take. Still nowhere near what I was making at the beginning of the year though (4-5x as much then).

Nothing to do with Metropolis, just the natural effects of the Ice Age. It will be interesting to see how the algo change effects things. Block times will be reduced, the ice age removed, but I haven't seen any information on a reset of difficult, etc to calculate profitability. I have a feeling margins will be very slim from here on out unless ETH rises above $500, which I honestly don't see happening anytime soon thanks to the downward sell pressure from ICOs. We're talking billions of dollars in ETH that are in the hands of ICOs and quite a few like EOS have been dumping every time ETH starts to creep up.
