Claymore's CryptoNote AMD GPU Miner v11.3

[gregor12]

Anyone else got problem with 280x rig? when i run single card it works fine, but when I add 2nd card it keeps crashing after few
hours of mining(6-18h). I get notice about virtual memory, i tryed to set it to 16gb and 32gb, still crashing. I got 8gb of ram and
280x toxic, on stock it works ~840hashes (1150engine 1600mem), if i downclock to 1100engine, 1500mem it works 860 hashes and
i still get crash after like 12h.
This is the msg - GPU memory allocation failed. Try to set at least 16 GB of Virtual Memory: Computer Properties / Advanced System Settings
 / Performance / Advanced / Virtual Memory

nope.

running 5 cards on 8.1, no problems.

it ran for 4-5 days before i restarted it.

How much is ur virtual memory 16bg?

Guys for anyone who wants to mine on xmr.farm with claymore should use port 5555... thank you

[spiffcow]

you guys seen this?

https://bitcointalk.org/index.php?topic=671784.0

Yup, hopefully it will be done soon. Nice to see an open source miner come out.

Guys, do not rejoice. It's more bad than good news. Now this adgoritm will be available not only for window miners, but also for Linux Miners too. So again significantly increase the diff of the network, but it is much worse than dev fee.

Wow greedy guy over here. I expect as the development of Cryptonote coins continues, the exchange rates will rise. I think this is good news as it means development for Cryptonote is advancing. I could be wrong though.

Unfortunately history has shown that there's not much correlation between hashrate and exchange rate.  For instance, BTC's hashrate is far above what it was 6 months ago, and its price is far lower.

Why is so small performance gays between my 270x and 280x ?
Both are 6x rig.270x get 2230h/s  but 280x only get 2800h/s

what this? -

07/01/14-19:57:13 - SHARE FOUND (target 62000) - (GPU 0 of 3)
WATCHDOG: Thread 8286904 hangs in OpenCL call, you need to restart miner
WATCHDOG: Thread 8286904 hangs in OpenCL call, you need to restart miner

It means that miner is unstable on your system. The best solution is to use "-wd 1" option to close miner in such cases and use script to restart it.

I got only 2500h/s with 6*280x @1160.What's wrong?To compare,My another 6*270x got 2230 h/s.So little gap.

Probably you have Hynix memory on 270x and Elpida memory on 280x. Elpida memory is slower, memory type is important.

Yes.My msi 280x does have elpida memory while my 270x have hynix memory.But when I calculate the profit( I mind at the same pool with different usernames).The 280x rig have almost triple the profit gained by 270x.Is that means the h/s is not that important?

only 8 gb lel.

h/s is important. Your question is related to pool, not to miner, pool mining for CN is a bit tricky about payments if you mine for a short time period. Leave both rigs to mine for a few days and you will see that profit is related to h/s. Or learn/ask details about pool payments

If you say so,it's not profitable to mine with 280x packed with elpida memory.
Why is that significantly important of memory type for cryptonight?

[mapleshadow]

280X is also not optimized or not fully support? Efficiency is too low, compared to other graphics card

[hero18688]

How about 290(X)

[Claymore]

CN PoW requires a lot of memory access, memory latency is very important in this algorithm. Memory size is important too.
290x hynix has 44 compute units, 4GB memory and gets about 740 h/s.
280x hynix has 32 compute units, 3GB memory and gets about 460 h/s.
Miner optimized for both these cards.

There are still plenty of space for improvement
My rig of 4 280x with hynix and 2 with elpida only got about 2800h/s.Not so good compared to my 270x-rig at 2250h/s.

Doesn't seem quite right when I can get my 7870 cards (hynix AND elipida) to mine at 350 h/s each.

Something doesn't make sense here.

[qqqq]

Claymore, do you plan solo version ?

What's wrong? Do you have same speed for both hynix and elpida?

[Claymore]

Claymore, do you plan solo version ?

May be later, I'm busy with new update. Right now you can setup private pool for that.

Ok i see.

[Sglasio]

Rig 3*R9 280x Vapor-x (Elpida) = has 1080 h/s
wtf(((
Maybe voltage or memory must be up?
Now 1.200v, engine 1070, memory 5500
