Re: Official CGMINER thread - CPU/GPU miner in C for linux/windows/osx

I tried cgminer on a couple of my boxes last night and woke up to find 3/4 GPU marked as DEAD on one and 2/4 DEAD on another. Trying to restart the DEAD GPU doesnt seem to do anything on either machine (restarting the ones still running did seem to restart them OK). Both boxes have been running for weeks using poclbm without errors. Running the 1.5.3 binary on Ubuntu (3xHD5870 and HD6310).

Anyone else seeing problems with DEAD GPU that won't recover unless cgminer is restarted?

nice, but how is there no risk of short circuit with all that metal?



Erm, no water or bare wire all over the place?

Most computer cases are made entirely of metal, and have well worked that way for quite some time.

no, because those graphics cards look like they are resting directly on metal, and what is protecting the back of the motherboard from touching the metal frame?  this is not a computer case.

The MB/PSU are in the wooden base and the graphics cards are hung from the aluminium at the top and rest on a strip of adhesive backed foam on the bar.

Aluminium eventually turned up so I upgraded from the wood Smiley.

Everything should be fixed now.
Looks like there are still a few problems genjix (this is generated when viewing a request)
Code:
Fatal error: Cannot redeclare enable_errors() (previously declared in /var/www/britcoin.co.uk/errors.php:4) in /var/www/britcoin.co.uk/errors.php on line 6

and http://support.britcoin.co.uk/ is still showing the internal error.

Do what it tells you to do and remove siteconf.py, then re-run configure.py/make/make install.

It probably depends what else you're using.

I use pyopencl which needs to be recompiled against the SDK when it's changed, but other than that I only change the path to the SDK.

Maybe I'm just slow, but how do you insert graphics cards into those? Or do you further divide them with x1->x16 converter cables?

I currently use x1 flexible risers with a cut in the socket.

I use http://www.amfeltec.com/products/x1pcie-splitter3.php - I might have a couple spare if anyone would prefer to order from the UK.

How much for 1 + intl shipping?

PM me with an address and if you want std or priority shipping and I'll get back to you with a price.

OK site is back up now. Waiting for DNS to propagate.

Server migration happens at midnight. Should take 4 hours.

DNS cleared and the sites back up from here - thanks genjix Smiley

As a Nominet member and tag holder it isn't always easy moving domains around.  But I wouldn't normally expect any issue with the nameservers unless someone changes them   Undecided.

The old IP on http:// will redirect you to the domain on https which won't connect, but connecting directly with https://75.101.180.111 does give the site but openid logins don't work due to the different domain. Adding an entry to your hosts file and then browsing to it and logging in works as it did before for me.

You shouldn't see any problems, I'm using 3x HD5870 (via a PCIe switch) on a single x1 slot Smiley.

Re: Will Many graphic card on one mother board work?

What motherboard are you using?

Whatever POS that came with the an Dell SC440.

Were you crossfiring the cards? Or in Windows XP 32bit (I think). Crossfire is forced to 4 GPUs max. One version of windows is reported to also have that limitation.

No crossfire, running under Ubuntu.

As for PSU problem, 6 5870s can run comfortably on a 1200W with no worries. The biggest worry is still as I said frying the motherboard by running so much power through it.

I'd also advise thinking about how you're going to get power to the 6pins.

I tried running with 6 HD5870 on a single MB but I could only get 4 out of the 6 to work properly, XFX couldn't see any reason why but figured it was down to resource problems with the MB - I've since changed to use 3xHD5870 per MB.

Re: Flexible mining proxy

I have not tested with many versions, but others have reported that at least PHP 5.3 is required to use the proxy.  I will add this to the readme at some point.

Using my changes above I've been using it with PHP 5.1.6 with no apparent problems, do you know of any other reasons why it requires PHP 5.3?

I'm not using PHP > 5.3 yet (CentOS 5.x) so I had to make a little change to get it to run without the DateTime class.

Basically I've replaced (format_date function in common.inc.php)
Code:
$obj = new DateTime($date, new DateTimeZone('UTC'));
$obj->setTimezone(new DateTimeZone($BTC_PROXY['timezone']));
return $obj->format($BTC_PROXY['date_format']);

with
Code:
return date($BTC_PROXY['date_format'],strtotime($date));

I didn't bother with the timezone as it looks like it's only used to display but that might be fixed with something like

Code:
date_default_timezone_set($BTC_PROXY['timezone']);
