Linux gives a better hashrate, also because of you can run it straight from the commandline so you can go ridiculously low with your memory clock.

Huh?, what's the linux command line option to dial down the memory clock? AFAIK the lowest memory clock speed (and the total range) is set in the graphic card BIOS, which can only be altered by reflashing.

Actually it will not just be the "curious" losing interest. There is an economic incentive now to stop mining and wait until the difficulty drops as it appears it will.

Simply put, it'll be cheaper to mine next week. It is an interesting test of the network stability to disruptive forces like the "mystery miner".

I've read that 2.1 is the best, and it is referenced here as a benchmark https://en.bitcoin.it/wiki/Mining_Hardware_Comparison

has anyone really tested?

Thanks, just trying to make sense of the data.

If things remain as they are it means that it is better to switch off your miner and start it again next week sometime (after difficulty drops) .... unless mystery miner come backs to stick the knife in again just before the next jump.

There is an omission in this tutorial that will send linux noobs astray on the driver install ...

at this point here

 
Quote
Open terminal and write the following command

$ sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
$ sudo apt-get install fglrx
$ sudo apt-get install fglrx-amdcccle
$ sudo apt-get install fglrx-modaliases

This should install Proprietary ATI Catalyst drivers.

Assuming a starting position as new clean ubuntu install, between setting your repository to ppa:ubuntu-x-swat and getting the drivers you'll need to issue a command to update the repository list in the machine else you will just go ahead and install the current fglrx drivers referred to in the default repository. (10.10) which is exactly what Mahkul got.

So it should read
$ sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
$ sudo apt-get update
### or alternately here you can open Synaptic and hit the "Reload" button, check ppa:ubuntu-x-swat is ticked as a repository in Settings->Repositories->Other Software ... also beware an "apt-get update will update your whole system which may take a while depending ....

and now it will get the drivers from ubuntu-xswat (if that is what you really want, I didn't use them)
$ sudo apt-get install fglrx
$ sudo apt-get install fglrx-amdcccle
$ sudo apt-get install fglrx-modaliases

Also here at the repository it recommends you completely uninstall all traces of any installed fglrx before trying to put another on the system ... and you can install a tool to do that (sudo ppa-purge ppa:ubuntu-x-swat/x-updates), so I guess they really mean it.

(also I'm a bit biased because I seem to have a speedy core that likes to run hot, fast and not stop ... it hangs when it ramps up after a getwork 1 in 1000 times??)

I have a fairly crappy net connection, so to deal with it I run one copy of poclbm with a -f of 30-60 connected to the pool and a second copy with a -f of 200+ solo mining. The second copy gets about 5% of the gpu power when both are running but it picks up the slack immediately if there is a delay in the get work.

Edit: I have a satellite internet connection plus I use a VPN to avoid the 250MB a day download cap, but that puts me last in line for getting any bandwidth. About the only way my connection could get worse is if i used Tor as well.

Hey Dude, thnx for your idea. I launched two processes on the problem GPU and it is now stable for over 6 hours (at best it was 1 hour before). If anyone is interested here is my convoluted launch process to get this thing crunching ...
in one terminal
$export DISPLAY=:0.(speedy GPU adapter number)
$fgl_glxgears
wait for some output to indicate fps are being crunched in gears then in another terminal (should have these commands ready to go with terminals and shells prepped)
$nice -20 ./poclbm.py -u miner0_username --pass=miner0_passwd -o mining.bitcoin.cz -p 8332 -v -w128 -f10 -d(speedy GPU)
and in yet another terminal
$nice -20 ./poclbm.py -u miner1_username --pass=miner1_passwd -o mining.bitcoin.cz -p 8332 -v -w128 -f10 -d(speedy GPU)
and as soon as processes report back hashing numbers kill (CTRL+C) fgl_glxgears.

Dirty hack I know but it works and is now stable, I can do a little script to launch this with a timer included. It was worth it because this core actually hashes 1-2MH/s quicker than other cores and wasn't worth sending back 5970 card for protracted warranty claim as it passed all the graphics tests anyway.

I think it is a problem with Xserver, (Xorg) fglrx kernel module and poclbm and a hardware weirdness whereby GPU doesn't like stopping and ramping up after a getwork pause but is fine if it is kept crunching maxed out .... maybe multiple processes can optimise GPUs in other ways ... -w 32 x 4?

8413  Bitcoin / Pools / Re: Cooperative mining (120Ghash/s) on: March 14, 2011, 12:55:04 AM
I am wondering if you had considered increasing the difficulty for your pool shares?, i.e. making it >1

It would reduce getwork calls across the internet, for the higher hash rate cards it seems to make more sense to be working on a harder problem, maybe a separate pool for bigger cards? They spend quite a bit of time waiting for the new work, taken in clock cycles versus wall-clock ...

Well, with well written miner, there is no reason why cores should wait on submitting shares; it can be done fully in asynchronous way (just send, don't wait - at least in blocking state - to response). Maybe the feature request to the miner developers? Wink Blocking getworks are another issue, but I'm working on it - its long polling and next stuff comming soon.

The higher difficulty for fast cards are good idea, it is already on my list for some time. It will definitely come, I have some algorithms to find 'idea' difficulty for given worker in my head; will see how it will work in real life Smiley. Keep in mind that higher difficulty does not mean only lower network overhead, but also higher variance in round rewards and maybe also some new kind of pool attacks, so it need some care to don't break anything.

Anybody know if the poclbm.py miner is asynchronous? (I'll ask m0mchill also I guess) It is apparent on screen that hash rate drops after a block is accepted and new one is begun but is that what is happening on the core?

I wasn't going to bother with overhead of solo-mining set-up just yet but maybe it is way to work around buggy fast hot core ... or maybe put two processes on same core so it is always doing something regardless of getwork calls ....hmmm, thnx for the ideas.

People sure like debt to be paid, violently if needed. This is why we got stuck in the fiat dollars regime.

Paying in Federal Reserve notes is not in fact paying the debt, it is swapping one debt for another since the federal Reserve note itself is a promise from the ruling oligarchic banksters to eventually pay the USA ... it is a gigantic debt-go-round and has been ever since Roosevelt screwed the gold pooch.

The end game is approaching fast now though and as the man, eventually all debts get paid, either by the debtor or the creditor. What's in your wallet, debt or credit?

Debt backed money requires continual inflation for the system to operate, and encourages ever increasing consumption because the longer you hold onto this kind of currency the less it is worth. In this way consumption is rewarded, but efficiency is not.

Couldn't have said better or more succinctly. BTC could easily be a net benefit for the "environment" (an ill-defined nebulous concept anyway) over the current dysfunctional monetary system.
