Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[merc84]

Hello. I recently got the r9 290 card and it doesnt seem to work to it's full potential. hashrate starts out great like 27 mh/s but it will drop to 21...after it heats up to 94c (which i read is normal for these cards). the miner will show irregular hashrate for this card only. my other r9 280x are all stable hashrates. this one will sometimes hit 23... 25... 21... 20.. should i change termal paste? change clock settings? get a big ass fan and point it at it? i have also had a bsod issue but i solved it by forcing constant voltage. thank you

okay, while trying to figure this out i've noticed in gpu-z that, unlike the r9 280x cards, the gpu core clock for the R9 290 is always moving. i noticed that i get a more stable hashrate after mining a bit (it probably adapts) but it's always around 700-800ish core clock. if i set it to the default gpu core clock value (through the miner file) around 940 i believe, or maybe i can even put it a bit higher, I should see a stable and higher hashrate. this is what i'll try tomorrow but i'd love to get an opinion from someone more experinced than me before i do it. all input is welcome. thank you.

The 290 is throttling due to temp, is the card in a case or open air rig?

94c is NOT a normal temp!
Anything above 80 is risky in long term - you're reducing chips life

Add 120mm vent blowing to the card and/or open your case

Hi

Neoscrypt good profit today, new miner ETH+FTC is good idea!

i guess your r9 290 is a reference design, they have a switch that throttles fan speed and increase the fan speed in catalyst.

prepare your ears though  that thing is louder than 10 280x combined LOL

Is anyone here using any of the old Stilt's modified bios for the 7950s or the 280Xs?

Is it worth it?

If the answer is yes, will the mods work only for ETH or for other algos as well (for instance X11)?

Thx  

The ROMS I'm using on my 7950s were originally modified by Stilt. He only amended the 1251MHz~1375MHz and 1376MHz~1500MHz strap I think. But it definitely helped my scrypt mining performance. I copied the memory timings from 1376~1500 to 1501~1625 and 1626~1750 because it allows me to overclock over 1500 on the RAM without losing performance.

For my 7970 I couldn't find his version of the ROM anywhere, so I did it myself. The stock ROM was painfully slow for mining, it was actually slower than my 7950s! After tweaking it I got another 2mh/s. So yes, it is definitely worth it.

The timings were originally for scrypt performance, but it will also help any other memory bandwidth/memory latency bound algo.

Mileage can vary. As someone said above, it made no difference for them. I think it helps the cards the most that weren't setup well by the manufacturer. Some get it right! Stilt timing tweaks made no difference on my two 290x.

Currently I'm only mining Eth and want to test the dual mining feature.

What DCR pools exist where I don't need to signup?

Thanks

[Marvell1]

so whats the best pool so far for DCR ? i dont think i can handle the heat but i would like to test these modded nanos on DCR see if the heat is bareable

Its not wise to mine with more than 1 gpu in a case even with side off or case fan, the top gpu will always be hotter due to heat rising from the card below it. If you have absolutely no other option then it is a must to have the side off the case and u can point a desk fan or the likes at the gpu. Also it would be wise to play with undervolting memory/gpu clocks to help reduce those temps as stated above 94c is bad for long term gpu health I would even consider 80c too high I like to keep my gpus 70c or below but 75c should probably be acceptable. Also did you try the -tt flag it will adjust the fanspeed to try maintain target temp ie -tt 75 will adjust the fan speed to try maintain 75c on the gpu.

ok decided to try suprnova for dcr

according to the calculator a r9 nano should do about 1700 mh/s of dcr but im only seeing 440mh/s or so

the funny thing is in dual mining mode my Eth mining has gone up around 5% from eth solo mining lol now im confused.

here are my settings
EthDcrMiner64.exe -epool coinotron.com:3344 -ewal xxxx.113 -esm 2 -epsw x -allpools 1 -dpool http://dcr.suprnova.cc:9112 -dwal xxxx.113 -dpsw x -allpools 1

I also noticed a very slight increase in speed for eth when dual mining compared to just mining eth using r9 280x. 440mh/s sounds reasonable for dual mining my 280x get ~ 285mh/s each when dual mining.

You should increase the dcr intensity, especially for nano. It is easy - just press + or - in the mining window to find Your sweet spot
You can also set the -dcri parameter in the bat file.

well unfortunately dual mining comepllye killed my 7 nano box, now its in a crash dump loop windows 10, ill re-install tomrow and try again

i think youre right on the intensity, i could probbaly get close to 900 dcr and still get around 180mhs of eth with this miner assuming the box stays up next time.

I went from 173 mh/s solo mining with eth to 190mh/s and 3000 mh/s dcr 

I would be happy with 170 eth and 7500 or so dcr.

it-s an open air rig. temp control and cc does not work as card will raise above temp secified and under the clock specified also. i am now also experiencing freezes... after a few hours like 5. the computer will freeze i asume this is due to high temp. i will try to raise fan speed to 100%

this is the card https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTgfA-4gkR-AAtI2JqYStf_R9WOBog7R4tQ23zYTTT345TuOLjp8Vw-4Pk

What DCR pools exist where I don't need to signup?

Thanks

zpool.ca

just provide BTC address

[citronick]

so whats the best pool so far for DCR ? i dont think i can handle the heat but i would like to test these modded nanos on DCR see if the heat is bareable

suprnova has a big DCR pool but I switch to zpool because no registration needed just put BTC address as payout

Is it possible to add option to restart miner after some ethereum shares rejected?
Today I found my miner works, but something wrong occuers with stratum. And all shares that miner found after that was rejected.

ok, this helped a lote. temp is now around 86. i think this may fix the freezing issue, which was the worst part. still, should i change the thermal paste? I have never done that before... so I dont want to do it unless I have to or should! would that help? should i change core settings also now that the temp is lower? maybe higher gpu clock and lower memory? can anyone give me a specific value?

thank you for your help so far guys.
