Running a 12 core system with a 970 GTX, and trying to figure out if I've done something wrong. Windows GUI is reporting ~200H/s for CPU and ~15H/s for GPU. I'm used to running GPU only mining (was on YAAMP forever), but its been my experience that GPU should be faster than CPU. System is fully updated on latest software / patches / drivers. Everything runs as expected against YAAMP clones, and SimpleMulti, so I'm 99% sure its not my hardware.
I've also got roughly 40% bad shares, and none of the logs will open from the menu for me to try and do any of my own troubleshooting.
Might help to mention that I'm using the GUI miner, set to Smart Miner, which at this time has been on XMR for both CPU and GPU, with FCN set for merged mining.
Anyone? Opened a ticket as well, but thought I might get better / faster information from here.
thanks!
UPDATE, setting my GPU intensity (unsure how I missed that) to 2-4 dramatically improves the GPU speed, however it causes alot of GPU kernel crash and recoveries. Because of the frequency of the crashing, I got a warning that the miner has been blocked from accessing my GPU.
Looks like I'm running stable on Intensity 2, but the GPU speed doesn't appear to be stacked with the CPU when looking at the website dashboard, so I can't tell if it's actually doing anything. Still having issues with high failures, and can't use the logs in the menu. Calling it a night and will hope its better tomorrow.
Smells like a power supply issue to me. Are you sure your PSU is capable to handle the load of both a 12 core CPU
AND a 980GTX, at
FULL throttle? If there's not enough juice the issues you've mentioned are the most common for someone to observe. If you want to test this, just run only the GTX for a couple of hours (rise the intensity at the highest level possible) and see if it comes up with errors. Then switch to CPU mining only, without the GPU. Observe the results.
FYI: I'd go with at least 1KW PSU for such a setup if I were you...
I don't have a 980 GTX, I have a 970 GTX which is MAXWELL based and uses quite a bit less power than a 980 GTX. I'm also only running a single card, no SLI. I had no optical drives, only SSD, water cooling in an A/Ced house, and minimal accessories via USB. This machine is designed to be cool and quiet even under load.I've got an 860w Platinum certified active PFC power supply. This system has been completely stable for the last year or so I've had it mining and gaming concurrently, it never crashes, and only restarts for updates. Based on the measurement of my battery backup system I'm only hitting ~250w usage while the mining is running @ 6 Cores with GPU intensity 2. I never said full throttle, you did. This is well within stable specs.
I've still got plenty of other questions about this thing though, so please don't get hung up trying to troubleshoot the GPU.
1) How do I get to the logs to try and troubleshoot or offer feedback when asking for support? The log's menu does nothing when I click.
2) Why doesn't the GPU hashrate seem to appear added to my CPU hashrate on the website's dashboard?
3) Why are 40% of the shares I'm submitting bad?
