Title: Can't use high TC, SMOS linux does not detect correct RAM size Post by: Valansch on February 22, 2014, 02:17:44 PM Hello!
I am using cgminer 3.7.2 and a R9 290 my cgminer.conf is this: Quote { "pools" : [ { "url" : "coinotron.com:3339", "user" : "Valansch.d1", "pass" : "1" } ], "device" : "0", "intensity" : "20", "vectors" : "1", "worksize" : "256", "lookup-gap" : "2", "thread-concurrency" : "32765", "gpu-engine" : "1075", "gpu-fan" : "40-100", "gpu-memclock" : "1470", "gpu-powertune" : "20", "temp-cutoff" : "99", "temp-overheat" : "95", "temp-target" : "90", "api-port" : "4028", "expiry" : "120", "failover-only" : true, "gpu-threads" : "1", "log" : "5", "queue" : "1", "scan-time" : "60", "temp-hysteresis" : "3", "scrypt" : true, "kernel" : "scrypt", "kernel-path" : "/usr/local/bin" } Whenever i tried to run it it gives me this: Quote Maximum buffer memory device 0 supports says 1073741824 [2014-02-22 15:05:45] Your scrypt settings come to 2097152000 [2014-02-22 15:05:45] Error -61: clCreateBuffer (padbuffer8), decrease TC or increas e LG [2014-02-22 15:05:45] Failed to init GPU thread 0, disabling device 0 [2014-02-22 15:05:45] Restarting the GPU from the menu will not fix this. My system run makes no difference, i tried 4 and 8 GB. Can anyone help me? :( EDIT: I tried the command free It gave me this: Quote total used free shared buffers cached Mem: 2568836 545068 2023768 0 46168 238860 -/+ buffers/cache: 260040 2308796 Swap: 0 0 0 No the strange thing: I have 1*4GB of ram and 2*2GB. Right now the i have the 4GB plugged in, but changing it does not change the output. Any help? :( Title: Re: Cgminer error -61 Post by: Starscream on February 22, 2014, 02:51:28 PM Error 61 is occurring because of memory issues. Depending on how much RAM your system have, you might need to lower your TC value.
I got 4GB of RAM and the max TC I can use is around 24k~ Also make sure your batch file has the following lines included: "export GPU_MAX_ALLOC_PERCENT=100" "export GPU_USE_SYNC_OBJECTS=1" Edit: Also, you might wanna try sgminer. Title: Re: Cgminer error -61 Post by: Valansch on February 22, 2014, 03:04:40 PM Sorry i was missing some information:
I do know that TC is the issue, but lowing my TC, can't be the solution since i get less hashrate. I'm using SMOS linux, and my system should be able to hand 32k TC easyly, but it only detects 2.5 of my 8 GiB. Any ideas? Edit: With 2.5 GB of Ram i can support a TC of 15k Title: Re: Cgminer error -61 Post by: Valansch on February 22, 2014, 04:02:58 PM My Bios detects the Ram:
