[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

The pool software that slush wrote does a variable diff check every 30 seconds . Assume his pool would do something similar.

What does does a variable diff check mean?
How is that related to the previous discussion / to my last post?
Can you post a link that confirmes/explains what you've written?

[tiktoc]

It does what you mentioned in the last section of your second to last post.

https://github.com/generalfault/stratum-mining/blob/master/conf/config_sample.py

scroll down to the Pool Difficulty Settings

It actually checks every 300 secs to see if the miner is doing at least one share per a 30 seconds. Was on a phone before when I posted, so sorry for not meeting the aggressive citation and link checking for your needs.

Now all the computers are litecoin mining exempt one which is dual mining with litecoin and bitcoin at the same time with one cgminer software

Another issue which has arises is one 7970 is only mining at 557 KH/s every other card is hashing higher, I am currently setting up a bios flash to get the PowerColor to the GHz edition to see what happen. Wish me luck.

What does this have to do with Slush Pool?

Nothing But I still mine on slush

Let me know how this turns out. I have the GHz edition and can't get any faster than that.

Ckolivas said it's a known issue with GHz cards. I can't get my Gigabyte GHz card past 550KH either. If you want to LTC mine, you gotta buy a ref 7970.

Weird how my other 7970s of the same brand and model mine more than this card and I did nothing to the cards. One of the 7970 Powercolor V3 is doing 735 KH/s!!

I have not check the bios on all the 7970 and I am not at home to do the BIOS flash, so it will be a little later tonight.

Also none are GHz Edition all are standard clocks and all.

Oh joy.

Well the bios flash did not help....... at all. The Bios flash was successful itself but hashing wise no improvement..... I will continue to try other bios similar to the PowerColor One


Update: just look at the bios of the PowerColor that is running at 735 KH/s and I saw the bios is not on Techpowerup so I copy the bios and flash it on to the card in question.

Update 2: Switch Powercolor cards and the card with issues is now hashing 650 KH/s....... -_- I think I need more ram on the computer only have 2 GB atm.

Update 3: My hunch was right. Got it to mine over 600 KH/s (647 KH/s) Just needed to add 2 GB ram with a total of 4 GB on 32 bit OS.

I wouldn't have guessed RAM was the issue. I get the same hashing out of a vcard running in my AMD Sempron machine with 1 Gb of RAM as I do on my server with 2 quad core processers and 16 Gb of RAM.

Scrypt mining is weird alright, the computer above the computer I worked on, is working fine with 2GB....

also thread concurrency is 8192 if system only has 2GB, after I upgraded to 4GB I can go over 20000 thread concurrency no issues.

hah

ooops nope DIFF up!
Current Bitcoin block, difficulty:   245955, 26162875

[Binford 6100]

wow, round from hell ; )
7 hrs w/o a block
i know variance and luck/probability, nothing to worry, but it's interesting to watch

[roobkoo]

This block is a really bad joke :/

[bitzip]

Processing the current block for 8 hours now.  When will it end?   

[Smithers]

Has a block ever lasted this long before?

[cosurgi]

yes, there was at least one 12h block IIRC
