Title: Dual HD 7950 problem Post by: CR7xMarcelo on February 02, 2014, 03:42:00 PM I have with two sapphire's HD 7950's...
My pc randomly shuts down and my asus mobo tells me it detected power surges. At first i thought it was a faulty psu but now i changed it for a 850Watt gold corsair psu and the problem still occurs. Two cards bricked because of this random shutdown happening to often and luckily i could change them with warranty. This is my cgminer settings when im using the pc: , "intensity" : "12,18", "vectors" : "1,1", "worksize" : "256,256", "kernel" : "scrypt,scrypt", "lookup-gap" : "2,2", "thread-concurrency" : "16384,16384", "shaders" : "0,0", "gpu-fan" : "35-85,35-85", "gpu-memdiff" : "0,0", "gpu-powertune" : "20,20", "gpu-vddc" : "0.000,0.000", "temp-cutoff" : "90,90", "temp-overheat" : "80,80", "temp-target" : "65,65", "api-mcast-port" : "4028", "api-port" : "4028", "auto-fan" : true, "expiry" : "120", "failover-only" : true, "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "30", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin" } Title: Re: Dual HD 7950 problem Post by: CR7xMarcelo on February 03, 2014, 12:55:07 AM Bump i still have the issue..
Last setting: i 17,17 engine 1020,1020 Got 2x 600khash but surge detected by mobo after couple of hours Title: Re: Dual HD 7950 problem Post by: stacksmasher on February 03, 2014, 01:01:08 AM Take out most of that stuff... Lookup Gap ---- take it out hotplug.... ??? If you are having issues take out the "thread concurrency" until you get it stable Title: Re: Dual HD 7950 problem Post by: CR7xMarcelo on February 03, 2014, 05:17:21 PM Those settings are alwayse there when i save a config file?
