2.7.4 is saying that it's 2.6.6 and it won't start properly for me.

Re-uploaded with correct binaries.

New unstable version: 2.7.4

Fixed some shit. Added some shit. Will only call it stable once it's tested by others.

Full changelog

I upgraded from 2.7.0 to 2.7.3.  Two of my miners crashed w/o me noticing it.

On 2.7.4 now.  First thing I noticed is the efficiencies are consistent now across my miners.  Instead of some being way of the charts, and others just off the charts, now they are all off the charts like they are supposed to be.

All using local instances of p2pool.

M

Yep and true efficiency should be higher than ever.

What a rotten day 

You really need some rest.

Thanks. Plan to once a stable release is out.

Stable? 2.7.0 has been fine for me!

Thanks. Plan to once a stable release is out.

2.7.4 gets me ~10% less hashrate than all recent versions (including 2.7.1, 2.7.0 and 2.6.5 for fresh comparisons) on a 5870 with SDK 2.1 (ati-drivers 11.6) on Gentoo amd64.
Didn't test 2.7.2 or 2.7.3.

2.7.2/3 will not even work on sdk2.1. It appears the kernel changes are not so great for sdk2.1. Oh well.

I always got less with cgminer on 5870s than I did with phoenix.  Atleast that's how phoenix portrayed it, I'm not sure it was accurate.

Just succeeded in compiling 2.7.4 finally. Took me a while to figure out how to compile with ADL support.

Everything is running great so far and my WU has increased 0.4 from 2.7.3. I noticed one weird thing though; I tried accessing my pool info through the API and it keeps giving me this error:

Code:

Error: Could not find or load main class API

I'm not sure if this is because of something I missed when compiling though.

That just means you don't have the API.class file in the directory where you are trying to run it

Edit: and thanks immensely for whoever this was

Ahh, I was wondering how that worked. I'm still trying to figure out the whole API thing.

Don't forget to read API-README - it contains a whole section at the end about using miner.php
That will give you a web interface to the API - reporting and changing cgminer settings.

Yeah I've been meaning to try and get that set up. I'll have to take a look when I get back to my miner.

2.7.2/3 will not even work on sdk2.1. It appears the kernel changes are not so great for sdk2.1. Oh well.

There's a suggestion from IRC that those with ultra low memory clock speeds on sdk2.4/2.5 are seeing this, and going from say 150 to 250 is enough to recover it. Perhaps it's not the SDK at all but the memory speed.

EDIT: Just to further explain why these changes have been made to ALL the kernels. Basically there are some small probability scenarios where some shares are missed by the existing kernel designs. It's not a lot, but given btc mining is entirely a probability game, we need everything on our side.

Hello all. Can anyone help with configuring cgminer in ubuntu to automatically start?
ThiagoCMC in post answered but I don't now how to implement this. Is there any more detailed guide?
Thanks.

I have been in the same position and asked the same question. I got no easy answer an eventually figured it out for myself. Not before it cost me 2 dead 5850's. So go to the thread below. I will post how I did it in Xubuntu 11.04. It should not be a great leap to do the same in Ubuntu.

- Pick worksize 256 with Cypress if none is specified.

I wondered why recent git versions have been slower on my 5870, about 414 vs. 421 Mhash/s. Using worksize 128 brought it back to the old speed. (Using fglrx 11.12 and SDK 2.5)

I knowh you have scrypt... but 274 on scrypt on p2pool still not counting "Q:" correctly (stuck on 1 no matter of longppols and new blocks).
Using your latest binary form #1 post. Win7 32.

Yep, looks like the counter is broken just in scrypt mode.

Yeah sorry, it seemed that most people using 58x0 were using very low memory speeds and 2.1 sdk which does better with worksize 256.
