Keeps crashing after a period of time #8

I've been using a different version of CCminer to mine LUX without any issues on any of my rigs.

However mining RVN it seems like the miner is always crashing after 4hours at best.

Sometimes it doesn't even give me an error message, this happens on my rig with 24 gigs of physical memory. Sometimes it says: "An illegal memory access was encountered" - This happens on my machine with 4 gigs of RAM and 16 gigs of fixed virtual memory only.

Here are my settings:

ccminer -a x16r -o stratum+tcp://miningpanda.site:3636 -u (wallet) -i 19 --donate 1 c=rvn

I'm going to happen here, too

This seems to be a GPU memory-related issue with ccminer. Try lowering your memory OC or even underclocking memory a bit to achieve stability. x16r is not memory-intensive, so the lower memory clock shouldn't affect your hashrate much.

I'm running my 1070's / 1070ti's at -300 (in words: minues three hundred) on the memory.

Core overclocks are relatively tame (about +200) and have been tested with gaming workloads (Heaven and Firestrike) to be stable.

I'm going to try and run the core at stock next though .

Just to report back for people who might experience similar issues:

Make sure you have enough memory (physical / virtual) in the machine. Try running the cards at stock first, because apparently this algo is running unstable with overclocks that would be stable even for FireStrike.

I found that most 1070's / 1070 ti's are stable at a +125 Mhz offset on the core.

tpruvot had released ccminer2.2.5
