Tell me then why I don't have any cpu usage with even 12 intensity with 2.1, but have all up to 100% on one core (with 1 gpu miner) with all other sdk's? It's the same bug.
If you posted your driver version, OS and GPU config someone could try to unravel your issue but this is hardly the appropriate thread. Proof by counter-example: a lot of miners moved to 11.11 or 11.12 driver and reported no CPU-hogging issues. Therefore, the major CPU-hogging flaw has been fixed. Computers and operating systems are inherently very complex subjects and great many things can go wrong. Unexpected combinations of drivers, SDKs and system libraries can still peg the CPU but it's luckily relatively uncommon. Mixing x64 and x86 code can be a real pain. EDIT:: Con, latest git works like a charm  The GPU order has changed on my Debian machines, though. I fixed it already, just said that he has the same bug. Sometimes it's a very minor cpu load with low intensity/aggression, but it's the same issue. Read this reply and 2 next ones. https://bitcointalk.org/index.php?topic=56740.msg718469#msg718469 And btw I use intensity @ 9 right now. |

This is the infamous cpu bug.
No it's bloody damned not. THE cpu bug would eat a whole core no matter what intensity/aggression you'd chosen. It was caused by AMD's driver fuck-up and has since been fixed. There have been some OS-specific CPU hogging issues, eg with Ubuntu. Do the research first and don't post misleading and inaccurate information, k? Tell me then why I don't have any cpu usage with even 12 intensity with 2.1, but have all up to 100% on one core (with 1 gpu miner) with all other sdk's (in case of Win7)? It's the same bug. It's a slight usage ~15-17% on one core, if I use buggy sdk and aggression 9, with 8 - zero usage. Higher intensity > higher cpu load with buggy sdk's, cept 8. |

when using anything above intensity 9 on my 5970 w/ 11.12 drivers. The cpu usage is pegged... 9 and below cpu usage is 0%
Any reason why its higher on I 10+? thanks

I run WRT54GL's with DD-WRT firmware, I have about 8 across my house, from router modes to wifi extenders and even vpn client/server. Works wonders and very cheap, you can also overclock their cpus  Funny you should mention that. I just ordered this one off of amazon. http://www.amazon.com/gp/product/B000BTL0OA/Gotta love their prime program! Wireless G. Ouch.  Pretty bad choice imo, even for a pure WAN router, because it's pretty unstable with high load and stops working after some time even with 5 mbit fully loaded connection, not to mention it's a dinosaur. Why not D-Link?  Rock solid stability even with 100 mbit download/upload and also support custom firmware, DD-WRT as well. And even cheaper, if talk about DIR-615. WRT54GL (200 mhz & 16 mb ram) = $49.99 vs DIR-615 (400 mhz & 32 mb ram + wireless N+ 300 dual band) = $38.21. |

Ok, I'm running 2.1 SDK now, but most of gpu stats (like temp, clocks, voltage, etc) isn't showing in gpu menu. However yesterday with 2.1.2 and 2.5 it worked fine. Using 2.2.0 now. UPD: oops, looks, like missing "[C]hange settings" option in 2.2.0. That happens when cgminer doesn't detect ADL support. For me it happens when using remote desktop. The change in driver version is likely coincidental. cgminer makes changes to cards and gets "stats" via ADL. Are you accessing the rig remotely? If not try a reboot and use cgminer before anything else. I have seen AMD ADL driver? service? crash and that causes those options to "disapear". No, I don't use remote desktop. ADL is working. Ckolivas has figured out the problem and made a temp fix. Read the thread a bit further. |

Do I need to enable engine clock autotune for "temp-cutoff" activation? Or it's active by default?
You need to enable --auto-gpu .However if you dont give it a range for engine clock speeds, it won't adjust any clock speeds, but it will still cut off the device if it hits the --temp-cutoff threshold. Great, thanks! |

But why 2.1.2 don't have such issue then?
It stopped after it found the first device. 2.2.0 finds all the devices and then reorders them correctly according to their PCI bus position. As I said you were lucky it wasn't giving you temps and fanspeed for the 4250 instead because it happened to put the 4250 second in the driver order even though you physically have it first in the slot - You can see it has a higher adapterindex in that list despite having a lower busnumber. As for a solution to this problem that is correct as opposed to "lucky"... I'm thinking, but I have no ideas apart from explicitly telling cgminer at this stage. This won't be the correct fix, but this exe should work around the problem for you for now (put into 2.2.0 directory): http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe Yeah, it's working, even with 2.1 sdk. Thanks! |

I hesitate to use 2.1 SDK, because I want to use the computer during mining.
Why you can't use it during mining with 2.1? Have no problems here, even playing in Skyrim without losing mhashes. I use internal 4250 to offload 5770 tho. |

Question: Can your other device (4250) mine?
I guess you don't need to answer that, I checked. So this is the problem. One device that can mine and one that can't. There's already nothing to correlate openCL devices with devices that appear in the ATI display library apart from "how many there are" and "in what order they appear". Put a non-opencl device in there (like the 4250) and it's a mess... GAH. Nothing short of some kind of massive whitelist will fix this. If it worked previously you were lucky it wasn't monitoring the 1st card instead. EDIT: This recurring problem of having no way of correlating opencl and ATI devices is getting seriously long in the tooth. Can we get a re-post of those facepalms please? But why 2.1.2 don't have such issue then? If it worked previously you were lucky it wasn't monitoring the 1st card instead. 2.1.2 hardware monitoring is working, right now, after I tested 2.2.0, without problems. So maybe just a bug in 2.2.0? |

Well that's interesting, you're getting the "adl found more devices than opencl" problem. How many GPUs do you have? Just one? Did you change anything in your driver setup at all? What output do you get if you use this http://ck.kolivas.org/apps/cgminer/temp/cgdebug.exe in the cgminer directory the same way you would use cgminer.exe and start with -T ? It will give more information about the devices with lines that look like this: [2012-01-22 17:31:58] lpAdapterID 20016752 iBusNumber 1 iDeviceNumber 0 iFunctionNumber 0 iVendorID 4098 strAdapterName AMD Radeon HD 6900 Series strDisplayName :0.0 lpInfo.strUDID 256:26393:4098:12583:5762
2 gpus. 5770 and internal 4250 (set as primary). And no problems with this setup and v2.1.2. Driver installed in XP is 11.12 and 2.5 sdk, nothing else.  |

Thats what I have with these parameters.  |
|
|
|
|
Err, hardware monitoring in 2.2.0 isn't working even with 2.5 sdk. Just checked with XP.
|
|
|
|
No idea then I guess I'll just switch to 2.2.0 and 2.5 sdk with XP, when I'm not around/night. Because gpu clocks/temp autocontrol is essential for me. |

Plus I can't use any sdk higher than 2.1, because of cpu bug.
By the way, "cpu bug" has nothing to do with SDK, only the ATI driver does. Others saying that cpu bug is in SDK, not in drivers. Plus, I've 11.12 installed (tested 11.6 as well) and I don't have this bug with 2.1 sdk, but with just switching to 2.3/2.4/2.5/2.6 the bug "suddenly" appear on W7 x64. Can you fix 2.2.0 version so I can use hardware monitoring with 2.1 sdk? It's working in 2.1.2, so why not in 2.2.0? Btw can I change for example phatk110817.cl on phatk 2.2 kernel from Phoenix, by just renaming it's kernel.cl to phatk110817.cl and replace the default one? It will work that way? Mystery. That does not make any sense about the SDK using CPU. I suspect you are actually having conflict issues with the files on your installation rather than anything to do with the SDK itself. Nope. I'm deleting from Win32 and SysWOW64 folders all sdk dlls (amdocl.dll, amdoclcl.dll, OpenCL.dll) all the time after sdk deinstallation and removing all remaining ati dlls and registry crap with Driver Sweeper. Maybe it's somehow related to enabled integrated gpu HD4250 on motherboard? Btw I don't have this bug with 11.6/2.4/2.1, 11.12/2.5/2.4/2.1, on WinXP (32 or 64 bit). But only 11.12/2.1 combo is working for me with Win7x64. And not only for me. https://bitcointalk.org/index.php?topic=61340.0 I hear that putting the .dlls into the cgminer directory on windows will allow you to run it with whatever sdk you want.]I hear that putting the .dlls into the cgminer directory on windows will allow you to run it with whatever sdk you want. If no other OpenCL.dll is installed into Windows folder. |

Ok, I'm running 2.1 SDK now, but most of gpu stats (like temp, clocks, voltage, etc) isn't showing in gpu menu. However yesterday with 2.1.2 and 2.5 it worked fine. Using 2.2.0 now.  And phatk is used by default or phatk2? Looks like phatk. Have lesser mhashes, than in phoenix, with same intensity/aggression - 222 vs 219. UPD: oops, looks, like missing "[C]hange settings" option in 2.2.0. You need sdk 2.4+ for full hardware monitoring support. It's called phatk for simplicity but really it's phatk2.1. I've 2.1 sdk installed only currently and hardware monitoring support is working in 2.1.2. Plus I can't use any sdk higher than 2.1, because of cpu bug. And why not phatk2.2? It's faster. |

i'm guessing it's megabytes (not megabits) right? see if your router can log the bandwidth used + # of connections.
When you order Internet connection service the ISP usually provides the speed in Mb not MB. Bandwidth is listed in Mb. Storage sizes are listed in MB. Usually MB means megabyte, Mb=megabit, for bandwidth as well. http://en.wikipedia.org/wiki/MB And as for router I can recommend D-Link brand. Even mine cheap D-Link DIR-615 working without probs by downloading\uploading for example, torrent, with 350 connections and 5-6 MB/s. |
