I have 40 GB virtual memory. It crashes with both included test bats, maximum time I got it working with 6 cards was 10 minutes. I tried intensity 30 but it doesn't help, just lowers hashrate. Also tried the #6 version you sent (it was faster at 900 total) but it does the same system crash after a few minutes (sometimes after seconds). I've been playing with the miner whole day now and I think it just uses too much CPU for 6 cards to work properly. I tried to run it with 1 card, the CPU load was around 70 % and it didn't crash the system but came up with an error "can't get block height" or something in 15 minutes. This causes a popup box and the miner restart loop doesn't run till you manually close the popup. I didn't shoot it up again but I think it won't crash the system with 1 GPU. However with 6 GPUs the CPU load is 100 % and I can't even open afterburner because the PC is so laggy. Seems that this miner doesn't work with low level CPUs with 6 GPUs or has anyone succeeded running 6 GPUs stable with G1840-like CPU? Why does it stress the CPU so much anyway? I would love to have a fix for this or a refund if the CPU is indeed limiting the miner because that isn't mentioned anywhere and I can't use it as is.

What TDP? Kinda misleading to market the miner doing those hashrates if you got them only with big overclocks on a good GPU. The opening post makes it look like those hashrates are just normal stock rates that you get off the box. I've got a full rig of 1070 g1 gaming cards and they wont overclock on core past +50 on 100 % TDP without the miner going crazy with ridicilous high hash numbers. I actually tried tweaking this on 6 different 6 GPU rigs (different brands) and couldn't get any of them working so all the GPUs would be over 9 Mh.
