Claymore's CryptoNote AMD GPU Miner v11.3

[kqpahv]

@mirny GPU-Z - Graphics card tab (the default tab that opens) on the left hand side 10 or so rows down is the field "Memory Type"
Mine says GDDR5 (Elpida). I would assume yours will say GDDR5 (Hynix).


I have an update for people as well with the 280x issue. I have found a repository of STILT's BIOS for the 280 cards here:

https://mega.co.nz/#!45pk0ZiB!UXqe0mwS4HepxmIKAOpNtWNNRyoci_jD-bo49DTRb6o


Also, I confirmed that the flash was successful using GPU-Z and the card performed slightly worse and REALLY bogged my system up so that it was definitely unusable while mining. SO STILT'S BIOS is not working for me. Or perhaps the BIOS was not actually STILT's but the flash was successful according to the difference in BIOS enumeration and the fact that the BIOS loaded. I tried another BIOS I found online and it wouldn't even flash.

Anyways, that's all for my update. Anyone else having issues with the 280x feel free to try the link I provided and see if the BIOS in there works for you. I used the ATI flash utility to flash it. That I found here:

My GB 280x's are also with Stilt's bioses and I am still getting 360h with them...

Hello, sorry to say but v3.4 still seems to have the Monero pool disconnect issue, been testing it against my pool (cryptonotepool.org.uk) so I see from both ends

Please send me complete log so I can check it in details.

Hello, sorry to say but v3.4 still seems to have the Monero pool disconnect issue, been testing it against my pool (cryptonotepool.org.uk) so I see from both ends

Running cpuminer-multi and GPUminer 3.4 on same Win8x64 PC, with 270X

The stratum stops responding for about 10 secs whilst it waits for the daemon to backup its blockchain. Claymore miner doesnt report disconnect at this point, but stops hashing shares, 30 minutes later it says "no new job received for 20min", despite having received jobs for last 30min and not doing anything with them I then restarted the pool which caused a proper stratum disconnect, which Claymore registered, reconnected and then waited 30min before reconnecting and receiving new jobs, but not hashing any shares. Throughout that period cpuminer-multi only complained when the pool was restarted and it had to reconnect.

Looks to me like the problem is caused by it being unable to submit a share, but I'm not sure, since there is a logfile here are relevant excerpts, please let me know if you need more details.

Thanks!

I had the exact same problems, but found them gone once I started mining without overclock. I've 290 cards though.

@trip96
now I see, I had old version of GPU-Z, so I've seen just GDDR5 in memory type,
so I can tell you now, that most of cards are with Hynix memory, just two Sapphires are with Elpida memory.
All ASUSes 280x, Sapphires 7970 have Hynix, but Sapphires 280x, comes with both types of memory.

@kqpahv
I don't know your clocks, but when you set memclock to 1700 it shoud be better,
let me know then, because I have one GB 7970 and with stock (1375) or even 1500 Mhz it was slow,
but after that increase, I start to get normal hashes.

Thanks for the suggestion but that utter crap Elpida memory Gigabyte always uses will never be able to do 1700Mhz  At least not on my cards.

After some research I can confirm that the reason of bad performance is Elpida memory type on GPU, not only 280x is affected but all cards.
I compared several 290x cards with Elpida and Hynix memory:
Stock 290x Elpida - 650 h/s.
Stock 290x Hynix - 740 h/s!
The bottleneck of CryptoNote PoW implementation on GPU is memory latency, Hynix memory is really much faster than Elpida. Latest GPU-Z shows memory type so you can check it easily.

Yea, it's really cool news!
Claymore, say please, and how much memory do you have (2, 4, 8 gb)? And what is bandwidth hynix in mhz 1600, or more?

I get 740 h/s on 290x 4Gb Hynix, 1000 core 1250 mem.

[Palad1n]

Thanks! OK. And what is type of memory hynix? DDR3-1333 mhz, or DDR3-1600 mhz?
Maybe it's not the most memory, and its type of frequency?
For example there is a Corsair memory frequency DDR3-2400mhz.
Maybe the more mhz is better, 2400, than 1600, what do you think about it?

increasing gpu ram speed help to get more hash?

edit:it does but not too much

[trip96]

Bummer about the elpida memory. Also sucks that stilts BIOS does not work for me either.

Claymore, Anyway of getting around this via programming? Perhaps another BIOS would work or are we simply SOL?

[cava]

The linux version please!

[dunchy]

Wha's the average power draw of r9 290 ? Above 300W ?

...what?

GPU ram, not system ram.

Claymore, please check 14.6 driver for AMD. I get 385 h/s per card. I use 3x270X (Sapphire Toxic)

[Palad1n]

Mining MCN on minergate needed...
Minergate added MCN.
Currently 3.4 miner not support MCN.

it was a problem of the pool instead of miner.

Yeah, i got 1160 h/s for 3 - R9 290 on 14.4 (Win 8.1 64 bit).  So almost 400 h/s each one  

I'm gamer sometimes, so 13.12 for me is impossible...

[Claymore]

It's very easy to make miner use 13.12 even if you have installed 14.x:
https://bitcointalk.org/index.php?topic=638915.msg7196535#msg7196535
Just copy "amd_opencl64.dll" and "amdocl64.dll" from v13.12 to miner folder.
Probably I need to put it to OP.

Can you post your *.bat file for MCN mining on MinerGate???

That don't work for me, still poor hashrate (i have 14.6 on one computer only, but still)
