I am using the pre-compiled cgminer 3.7.2 - however I notice that it is no longer available, which is probably the reason why you needed to compile it.  When you compile, you will need to enable scrypt - check the readme.txt file - you need to have --enable-scrypt when you compile, because it is disabled by default.

[Edit]  If you still have trouble, I should have a copy of the bz2 file on one of my mining rigs that I could put somewhere for you.

That is correct.  When you see the games performance gain with crossfire or sli, it isn't +100%, but generally +90-95%.  However, each card is different, and it must be possible that in some cases, crossfire actually performs better than individually.  I know that my cards don't do the same as reported by others - I have to set different intensities to get the same hashing rate across the cards, so either something in my configuration is doing this.  By the way, some people say that we must use dummy plugs, and others say it isn't necessary - I only have a monitor connected to the first card, and nothing on the others - maybe I should try the dummy plugs, anyway, just a thought.

Definitely!  Even though people use the same configuration, each card actually is different.  For example, when I was running 3x 7950's at default clocks, each 7950 would give me 582Kh individually, but together - only the first gpu gave me 582Kh, the other two only got 530Kh or so - when running at intensity 18.  However, if I bump up the other two cards to intensity 19 each, then all three would give 582Kh.  With overclocking, they can get 630Kh without getting two hot, but here in Australia - it is summer, so I don't like the gpu's getting to 90 degrees, so am keeping them under 85 degrees - once we get to winter, I can run them harder.

[Edit]  Also, the cgminer version does make a difference - the latest is not always the greatest.  I am running 3.7.2 - the last version to support gpu's.  I feel that 3.6.6 was giving me slightly better hashing, but am staying with 3.7.2.

Cgminer and other miners will utilize all gpu's installed in the system - those that are configured, that is.  There is no need to use crossfire to combine them - actually this might make it hash less.  I did have 3x 7950's on one machine running Linux, all hashing well - until one 7950 decided to have a fan failure, now waiting on a replacement.

If you were gaming under Windows, and wanted more performance, then yes - crossfire them.  You can still use the machine for mining when not gaming.

I started mining at xtrapool.com (8th January) then noticed that the pool wasn't confirming coins even after many times the confirmations required.  I stopped and soon after found that I was getting login errors on other pools where I had used the same username.  xtrapool is no longer around so maybe this is where it started.  Lockouts started happening on other pools like n0nplusultra.net and valid-error.com soon after I had registered with xtrapool - I have since created new accounts so that I don't use the same username - a pity, but it appears that it is a necessity.  I like the way that other pools now require you to login with your email address, but displays the username if you don't set it to anonymous.

BtcLtc is the only exchange I know of that lists PPL.  Current value is 0.210010 CNY - not much, but it is possible to solo mine, and you get 1.25 PPL for each block.  Average network hashrate goes from about 1Mh to about 10Mh.

Still no word from coinmine as yet - some of my NBL should have reached 120 confirmations by now, but balance is zero for both confirmed and unconfirmed.

Anyway, we are at block 39314, difficulty change in 1006 blocks.  Sorry it has been slow going lately - I had issues with my mining equipment with a 7950 being replaced with a 7970 that runs the fan at full speed and keeps getting throttled by cgminer and gets less hash than a 7850.  The 7970 is now sitting in its antistatic bag waiting for my 7950 to come back.  Have built another 1Mh miner, but need to wait for a case to come in so that I can run it properly.  I don't want to run an open rig like I have been doing previously so want to put the miner into the garage so that the heat and noise doesn't bother us.

All is good now.  When the sync finished with the 1.4 client - my balance showed 50K+ but a lot of other transactions were confirmed, so ran the repairwallet - got me back the other 110K+ plus the other transaction that I was checking on - so everything is fine now!

I hadn't run my Grain client for nearly two weeks - when I ran my client, it eventually sync'ed, but was still many thousands of blocks behind.  Then I realized that I was running the old 1.3 version.  I downloaded this 1.4 version but it still wouldn't sync so have decided to reload the blockchain from scratch.  Hopefully my coins will come back when the blockchain has fully downloaded - all my transactions now show unconfirmed (160K+ GRA).  The old client must have gone onto the wrong fork.

I sent in a support ticket for coinmine.  I logged in today to check on how my coins are going - all of my unconfirmed NBL are missing - not showing up anything at all.

Great!  Thanks!

Hi - I am just passing on information from other forums, that the developer has submitted.  You can see yourself at:

https://cryptocointalk.com/topic/3464-its-nearly-block-417000-please-update-to-orb-version-13-once-reached/

It looks like 300 more blocks before mining can work again.

xtrapool is gone - no longer on the network.  Anyone mining there (including myself) has lost their mining time.  I was mining CAGE but moved elsewhere when the pool stopped confirming blocks and started to lag everyone else.

I recommend that if you mine with new pools, have a look at the statistics and routinely log in to the dashboard and keep track of what is going on.  Sometimes pools hang and stop confirming - it is best to open a support ticket, if it allows, then mine somewhere else until the problem is resolved.  That way, you don't spend a whole day mining and find that the pool had crashed.

If your wallet address starts with K then it is a NYAN coin address, but if it starts with a 9 - it is a NYN coin address.  Bitember is mining NYN coin - you will need another wallet.  I will check where I downloaded it from and post it here.

[Edit]  Wallet link for NYN coin can be found here at this page

Great - good to see you add your hashrate to the pnw pool.  I am waiting for this block to finish so that I can make a hardware change on my main mining rig - swap a card.

I am connected to these two nodes, then you can try myself - usually the nibble client is running 24/7 unless the laptop gets rebooted.

addnode=77.251.56.232
addnode=54.200.132.23

Mine would be

addnode=124.189.53.150

Thanks!

Does anyone know who to contact re bil.cipherpool.com ?  I have been locked out for several days, the support link only says that the product is as-is, so how do we get support?

After I replied, I did try solo mining.  The problem was the cgminer reported a high difficulty.  The share required was 401K (at the time) which would take me a couple of hours unless I was very lucky.  Then the PoS blocks were coming through every 32 or 31 seconds like clockwork - each time cgminer would then work on the new block, so in reality the block time is 30 seconds or so, but the difficulty is too high for solo mining - at least for me with only up to 2Mh.

Thanks!  The last sentence, are you saying we should or shouldn't solo mine?
