Hey peeps, I built a 3 card gpu mining rig with an r9 270, r9 390, rx 480, Ive been trying to mine monacoin using the mkx lyra2rev miner with windows 10 but Ive been having so many problems that I started to mine other coins that are cryptonight since I dont seem to have many problems with that,
now before I built this 3 gpu rig I was just using the r9 270 with the mkxminer on windows 10 and I had 0 problems, I was getting 14mh steady and up to 16mh if I pushed it, now that I added all 3 gpus I can barely get it to run for more than a few minutes without it crashing, no overcloaking, for the few minutes that it does run I get about half the mhs I do when I run them solo, I tested all cards by them selves and the rx 480 gets 28-30mhs and the r9 390 26-31mh and the r9 270 14-16mh, but as soon as I add all 3 together I get nothing but problems, they all get really hot super and if I crank up the fans to 100% the stay cool but it all still crashes, Ive tested both windows 7 and windows 10 with the same results, any help or suggestions would be much appreciated, thanks in advance

Are these GPUs all in the same closed case? That could be creating an issue with overheating that you may not have with Cryptonight (since it's allot less intensive on the GPUs). As for crashing and lower hashrate, have you tried increasing the virtual memory size (page file) to equal that of your combined VRAM plus a bit extra?
hey thanks for the reply, all the gpus are in an open air rig by an open window with an extra fan on them, its really crazy My xfx rx 480 goes straight to about 76 degrees c, I can get the temp down to around 68c if I under volt to around -80 to -99 but its not stable and another thing is that the temps on all 3 gpus show wild fluctuations from 40c to 78c, just constantly fluctuating, Ive uped the vmem and have tried everything I can think of, I am reading on these forums and it seems that lots of people are having issues with this miner, I just cant seem to figure out what the deal is and I guess until then Ill be using other miners, thanks again
