Topic: AMD 7970 LTC Mining, CGminer, Crash on LTC, not on BTC - page 2. (Read 11716 times)
From what I understand LTC is more memory intensive and BTC mining. When I OC my memory on my 7970 and they are watercooler my VRMs I say get to hot for my liking. Iv seen them in the 70c range or close to it. Sounds to me vrms or memory are overheating. I used HWinfo64 to get those stats.
Hi everyone.
I have a new Gigabyte 7970, the big version with 1100mhz core clock.
Card gets up to 730mh/s with cgminer on Bitcoin with 1180/1030 with temperatures above 90°, probably enough to make an omelette. Core voltage is unfortunately locked at 1.256v.
I have used this setting before for LTC on cgminer:
cgminer --scrypt -o http://eu-pool-d.give-me-ltc.com:80 -u Schrankwand.1 -p x --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256
I have MSI Afterburner running and set core clock to 1100 and increased Memclock slightly to 1600 stable. But that seems to be it. I get about 600kh/s and it does crash after some minutes.
I believe this card should be able to run at FAR higher ratings than this, especially considering that it is voltage locked at 1.256.
Problem description: While card runs stable at high hash rate and above 90° core temp at bitcoin, it near crashes on LTC within 5 minutes, showing complete screens in blocks, sometimes in blue, sometimes in white. Stripes, vertical, actually. On LTC it never even reaches high temp, maximum is 70° before crash.
Any help? Something I am totally fucking up here?
Drivers version is 8.982-120727a-144338C-Rage 6.
System is running on windows 8.
