Anybody have A2MEGA 110mh/s?

yes i had the same problem exactly like you said. i had tried to adjust the clock manually via ssh to force higher clock but no go, the driver pre compiled in the cgminer 3.9.0 its giving less work to the chips if u clock higher. Best is running 1200mh/s i get around 90-95mh/s at wafflepool. make sure difficulties set at 2048

i just received another similar 12mega from insmart its running 110+MH/sec because the miner able to adjust clock rate, voltage mV of the chips manually. It's far more powerful than the unit from innosilicon but i get a lot of heat from it. A2 from inno is running around 39-42c but the insmart unit running 50-57c big difference. well, u get more than 10mh/sec average ofcos it does came with 1150w PSU opposed to the 1000w from inno.

Inno A2 mega, 3 intake fans, 2 exhaust fans from delta.
Insmart A2 only has 3 intake fans but compact case airflow is ok.

thank's for reply in http://clevermining.com/ i have better hashrate 250-260mh total. At this moment in wemineltc i have 78205 on a2mega 110mh/s :/

Not a problem looking at wemineltc they look a little old as far as servers. Clever has a lot more money going for it. You can look at https://www.litecoinpool.org/pools to see how your pool ranks on being big.

I'm from Poland i use EU ASIC Only Server (1000 Locked Diff): stratum+tcp://asic1.wemineltc.com:3333 and i get

I have 2x Zeus 44mh/s , 1 x 30 mh/s, Gridseed set 42mh/s and a2 mega 110mh/s, a2 mega whetever pool i join is slowly :/ than 110mh/s

Once in suchpool i have 100mh and suprnova. Theoretically, this should be about 250-260mh and is 220mh / s (wemineltc) on coinotron I had 240mh / s Regards

Edit : i have second image http://www.iv.pl/images/48389080574969724082.jpg

Please help me! WUtility told 90mh/s AVG 110mh/s :/ http://www.iv.pl/images/48389080574969724082.jpg

Sounds like

You might try http://clevermining.com i know I have used it a decent amount with a few others (i tend to mine at multipools). Look into the difficulty and try a few out. There is a good explanation at clever on how to set it up in password http://clevermining.com/faq also make sure to mine to EU not US with it.

It sounds like you have the closeness down on pool. Check different pools, and different difficulties. If that does not do it I would contact seller and see what they say. If you are getting 90MH that is almost like one blade is not there, so might make sure gui sees all blades aswell.

Minereu do not lie, you have a lot of messages and even he admitted that Zeus does have a better machine. I've tried wemineltc ASIC port asic coinotron port (in this case at all kicking me 70mh / s) I am using the A2 mega with this link https://www.dropbox.com/sh/g8eg3goi11jkot4/AABbzkuI-dBTFX5sdqrRigMga?dl=0
Liteguardian asic port it's the same problem :/
Do you have any ideas what to do? Chips walk on 1200mh.

On suchpool.pw and suprnova i have 100mh/s for a moment :/

At this moment i change to stratum+tcp://asic1.wemineltc.com:3333 ane we see what's happends.

Are you mining with a pool close to you? What country is miner mining from?

Hello i have buy one A2MEGA from MinerEU.com and i have 110mh/s on scripta a2 / new a2 terrminator image but for pool like coinotron.com, liteguardian.com plncoinmining.org, wemineltc.com and i get maximum 80-90mh/s on pool. I have some Zeus 30mh/s and 40mh/s and i so better than A2. Manufactured told A2MEGA got 110mh/s and get 88mh/s always but Zeus told 40mh/s and i get 44 mh/s. Best wishes and maybe somebody have resolved for my problem?

Did you use the dedicated ASIC port at wemineltc?

At what settings are you running your A2MEGA? And which firmware do you use?

Hi,

Mining on some pools that are not optimized for ASIC miners could be a problem for higher power ASICs. multipools as well could have less hashrate due to coins with very low difficulty.

if the network connection is pool, e.g. Connect a miner from China to a Pool in Europe, it can be a problem.

P.S. we have not received any support ticket from any customer regarding this issue.

Thanks.

Did you try contact the manufacturer to see if it is your setting's problem?

I really don't know if you can say zeus is better then A2 chips. It's like apples and oranges. Zeus you can get at a low rate but you will have around 3 times the watts needed as a A2 chip.

I cannot say on A2Mega, but the A2Mini i would never trade its been a great machine and uses around 1/3 watts of zeus.
