Newbie question. I've set up a machine with BitMinter 1.4.0 and three GPUs (7790,7870, and 7950). The tachometer for the 7790 is nicely in the green part of the dial (272Mhps), but the other two are below the green. Does this mean I can get better performance with these cards? Is there a good guide somewhere?

Thanks for help.

do you use msi afterburner to set cards? 

 
 what are your cards getting.

  a 7790 maxed can push 305 

 a 7870 can run over 440   

a 7950 can go up to 550 pushed

My 7790 can do 330 (unlocked settings in Afterburner, core 1285 MHz)

Sorry, I didn't make myself clear. I wanted to know the meaning of the green bit on the tachometer, is it just eye-candy, or is it telling me something useful? If the latter, then what?

Watch the numbers, not the tacheometer... only them talk clearly if your setting are in good shape or not...

Question is  viesheateur at 355Gh cloudhasher? 

  I have my contract from them  they sent a nice email today. Here is a small piece of it.

Announcement - June & July Contracts

Hello Everyone,

As you are already aware, we are now in the month of July. This is the month where your contract starts paying Bitcoin to your Bitcoin wallet (some of you still need to set up your wallets).

In this quick newsletter, we want to address some common questions.
When does mining start?

Mining should start sometime this Month. We will surely keep you posted once a concrete date has been established. Many of you have not added your Bitcoin wallet address to your account. Please enter a valid wallet address as soon as possible. This can be done through the dashboard.
 

How do I add a Bitcoin wallet to my account?

Some of you still need to login to the site and setup your wallet. It can be found under 'My Dashboard' in your profile settings. Once the statistics and new site features are in, it'll be in a mining contracts section as well so you can see and configure all your stats in one place. ...

 >>> Seems  to be encouraging.

I am Hoping They start hashing really soon as my house is too hot and my gpu farm is about breakeven.

If I understood what you're talking about, the green bit is an indicator of the highest value since the tachymeter is displayed.

  In theory  if you are in the green you are in the ideal speed.

It is  Not always true you need to take into account:
 watts per hash use a kill a watt meter.  A really good gpu setup can give you about 3 hash per watt.

 3x 7970 underclocked to 500 hash for a total of 1500 hash can pull under 450 watts.  they would just touch the bottom of the green .   

lots of factors for best speed:
 your psu
 your mobo
 your cpu
 your room temp
your cards.
your cards temp
your price per watt of power.
BTC price .
If BTC is 200 usd a coin you could overclock and still make money even though  you waste power.
If it is the winter mining helps heat your house and lowers your heating bill.
 If it is the summer mining raises your ac bill

  At the start of green with a little bit of under clock  my setups get the best watt per hash.  Really important as I pay 17 cents a k watt.

 Summer power  bill was very high 641 usd. For June and it was estimate it should have been 700 or 720 usd.  Last month I earn 11.5 coins I sold them all at about 100 each so I still made money.

With my 7950's, I can get 590 on each @ 1120mhz and its stable.

Under the tune and tweak options if I uncheck manual vectors it increases hash speed considerably.  I haven't checked that against completed work units to see if more are actually being done, but I assume the increase in hash speed by unchecking manual vectors is better?

no more speed is only better if the watt cost is worth it.

 I can get 660 on a 7970 but watts will be  over 270.


 same piece of gear down clocked to 500  say .90 volts/ 880 core  1.5 volts 685 memory  will burn only 140- 150 watts.   so yeah 680 sounds good compared to 500 but not if i pull 270 watts vs 145 watts.    now my watt cost is 17 cents a k watt.  lots of are  people lower then me so oc may make sense. 

 In the winter I got a shit load of free heat so I oc'd and my winter heating bill went from 230 usd to 130 usd.  now the summer oc make no sense as my ac bill jumped so I underclock

Smart thinking, but not every 7950 can change volts I think ?   On stock I can concur 590 or more is possible, with watercooling maybe over 600 but Im not sure what work or score that should resolve to per shift


What drivers work best with this client, I have the latest but I read 11.1 are fastest.  I tried and failed to get it running on a few machines, its ok with any java I guess

[vince120]

I misunderstood for the colored bit : green area in then tachyometer of the bitminter client is ideal conditions whereas I thought you were talking of the colored plot on the website's liversats which indicates the higher value... Sorry.

It is possible, you can use one of the tweakers provided by other vendors.

For example, I have a Sapphire Vapor X HD7950 and I managed to tweak it with (in chronological order)
- ASUS GPU Tweak (http://support.asus.com/download.aspx?SLanguage=en&m=gpu%20tweak&os=30) whose graphs/sensors stay pertinents
- AMD Catalyst
- MSI AfterBurner (http://event.msi.com/vga/afterburner/download.htm)
- Sapphire TRIXX (http://www.sapphireselectclub.com/ssc/TriXX/TriXX.aspx)

They all work, some are slighty different, I prefered ASUS's one to do the first tweak and now I only check with Catalyst (because too high overclock uses more power and is less efficient if we look income versus cost)

some 7950 and some 7970 are locked

I have 2 kinds of 7950, the 3 of the Sapphire 3L's and one sapphire single fan model.  The 3L's have a switch on them to run at 1.169v or 1.25v.  I run them at 1.169 and get about 640Mhash.  Another machine with the exact same hardware only gets 615Mhash.  They both are xubuntu 12.4 and the only difference is one has Catalyst 12.8 drivers and the slower one has 13.4 drivers.  Besides that they are identical.

/edit  I'm running cgminer 3.1.1 on both. 
The other cheaper 7950 is locked at 1.25v an gets 630Mhash.   

I've managed to get all three cards up into the 675 range, but they aren't stable running that hard.  Only last a few hours before they hard crash the machines.

Nice to see the hash rate of the pool steadily climbing all week. Things have been really solid. Thanks for all your work, Doctor !

[mruiter]

Hash rate downbig time again to some funny crash in mint server.

I was just to late to see what was going on, but hashrate dropped big time on page, my ccminer switched to backup pool and was when i was looking switch back.

No server crash. But I see there has been two big traffic spikes. Perhaps DDoS attacks were able to make the network unstable for a moment before Black Lotus could mitigate.

[DrHaribo]

Black Lotus confirms small DDoS attacks that were easily mitigated. But you may have experienced short connectivity issues as their traffic scrubbing kicks in.

Hash power Climbing slowly again.

[vpereira]

what im facing the whole week are problems with myopenid. are they as well under DDoS attack? as soon as im able to login with it, i will try to change my authentication provider.. is that possible?
