OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Marrs]

I have a question, if someone maybe can answer.  I wouldn't not have thought this a valid question, but have run into it myself.  

--How does "System RAM" connect / associate with "GPU RAM" and "TC" in CGminer?

Example similar to what I ran into;

System mining LTC with 1024mb system ram, with say a TC- 10752
Change
System mining LTC with 512mb system ram, with same TC - 10752  <<<Error -5: Enqueueing kernel onto command queue. (clEnqueu
eNDRangeKernel)

Anyone have thoughts on how / why / what is making the connection with system ram?  Thanks in advance for any help.

The problem is with OpenCL being unable to allocate the gpu memory on a system with less system memory than it wants to allocate.

I'm not sure if there is any way to work around that, other than to add more memory to the system.

After 9 months mining, I fried a 6770 and 2 * PSUs. The 6770 has no physical signs however when mining it was reporting sick/dead after 10~20minutes for about 3 weeks. The PSU blew so I replaced it then it blew too so I ripped out the sick 6770, added a new PSU and things have booted up OK except for....I can no longer mine!

Upon starting up CGMiner reports that a card is already overtemp yet I am monitoring the card temp using a 3rd party which has it as 40ish degrees C when idling.

Ideas on how to fix...?

Someone please help me, I just built a small rig and got a Gigabyte 7950 in it.
I use all the settings suggested for varying hash rates on the charts and I cannot get it to work.

First off if I change the Memory clock either in the CGminer window or in the .bat and load it, my screen goes black and it all just locks up and I have to reset my PC, every single time.
Also, I cannot raise the thread concurrency beyond like 10600, it just gives me the GPU/thread disabling kernel error message, even though I did the "auto tune" test and it suggested 22400, I have no idea why, do I need more RAM possibly?

The only way I can get it to work now is leave everything default (1000/1250clock) and just put the intensity at 18....but it gets too damn hot, its open case with a bunch of exhaust fans, Its around 85-90 C right now depending if I just Accepted a share, it gets hotter, and this is only at a K/hash rate of like 570-600, can anyone help why my card is getting so damn hot?? and all my other issues I tried 20 first and it got up to 95 and just shut the card off similar to how it reacts when I increase the mem clock....

25 LTC to anyone or a group of you guys that help me solve this problem

Also in my pool it says I am only getting 46 k/hash on the card

At a wild guess - your config file may still be setup to include the other card?
(and thus the GPU settings are going to the wrong devices?)

[dbabo]

<cut off>
well, the intensity was set a -1 on the little machine that i am playing with. moving it to 5 raised the hash rate from 6Mhash to 10Mhash. moving it to 6 looked like it  caused the rate to drop a little, so 5 it is.

10Mhash/s? how do you get the Mhash ? ty

Did i mislabel? isn't Mhs, Mega Hashes? I've only been into this for about 2 weeks so it would be easy for me to mispeak.

eee, stop and reload..
you are talking litecoin? you are talking GPU mining?
may i ask how a tiny rig gives you Mega Hash/s? the top listed here is 7970(x2) in low megashas/s...
// i'm obviously missing something obvious. sorry about it.

I deleted the 2nd cards Intensity rating from the config and boot shortcut...hmmm...will go back and have a look at removing all the secondary settings within the config files...

If it works...some compensating BTC or LTC will be shelled out

Please please someone help me out here, btw I have 2 gigs of system RAM.
Also when I launch CUDAminer, cause I want to use my 570 (which is the primary card) to mine as well, it takes away from CGminer and my hash and everything starts going down. Why is that? I could have sworn you could run both programs at the same time to mine both cards, help pl0x!

heh, we are talking bitcoin GPU mining. If a good  video card can give 600+Mhs ( like a 7850), then a small rig churning 10Mhs isn't all that impressive. I'm not sure what you consider "low megahashes". everything is relative.

Wow - that's overclocked

Apparently you can get ~370MH/s out of a 7850 but I'd wonder how long it would last ...

my bad, that's a 100Mhs card, i got confused. I haven't had the chance to memorize the entire Hardware comparison chart yet. i occasionally get things mixed up.

yeah ipv6 doesnt even work

One question, if you launch your cgminer with "-s 5" what's meaning? I'm lokking in the readme file but i don't find nothing.

Dafuq... thx you very much. I was reading scrypt-readme T_T

Out of curiosity, what version was the last Linux binaries to support CPU mining before it was removed?

Thanks

None available. I am actively doing whatever I can to discourage anyone from finding a way to CPU mine if I can help it. It's bad for bitcoin, it's bad for the reputation due to illegal botnet virus associations, and [insert lots of other reasons I can't be bothered repeating here]. Spending $1000 in electricity to earn 10 cents unless someone is getting ripped off is bad for someone.

CPUmining ist not welcome here, if you need a miner get the best one: https://github.com/pooler/cpuminer/
since u got ur tool, dont talk about CPUmining anymore in here

EDIT: ck, if you want il remove it

Reading the script-readme is great and I'm sure the author appreciates it.  But the other readme's and the top post have allot of general info that applies to mining generically.  So it's probably good to start with the generic and then move to the specific.

It's allot to digest I know.  I have gotten my share of RTFM suggestions too
