changed ratio to 1022/1244 and bam! running at a stable 725 kh/s with 82temp still in case!!! Going to still take it out as a 2nd GPU will be added soon and then it will be a whole new ball game in temp. but yeah..planning on getting powered and well molex im not even sure how to hook that up but that lesson will have to be learned another day. My brain needs a few days off
Thanks for your help and everyone elses! If anyone needs a little help on tuning a GIGABYTE 7970 give me a hollaThe molex is connected to the riser, so as well as having your 6 and 8 pin PCI-E power plugs to the cards themselves, you plug another molex power plug from the PSU to the riser's molex connector. Easy peasy japaneasy
...I wouldn't worry about utilizing the molex's for 2 GPU's.. you should have more than enough power delivered from the mobo to the cards. Still get the powered risers for future proofing
Glad it's all working out for you in the end man - take some rest and let your baby hash away for a while
