BitShares PTS / Re: fast AMD OpenCL PTS miner released
« on: February 17, 2014, 02:59:38 am »I have previously reported some windows updates changed some of the performance of the 0.1.4 version... but I got mistaken by the fact that I am using the second GPU for my monitor... and the AMD driver has a "flaw" (in my opinion...) that when the first card to be detected over the PCIe has no Display adapter connected to the RAMDAC... it does not "turn on the full potential of the GPU"...
I mean if you walk away from a computer and the monitor turns off, why keep things running and wasting energy, it is a brilliant energy saving feature 99% of people benefit from, except miners... you need a dummy plug that will trick it into thinking there is an actual monitor plugged in... I'm assuming your 270 card probably came with a DVI to VGA adapter of some sort, most seem to, you can use the website below and some simple resistors from an electronics store.

some people who use certain powered risers, won't need this as the pcboard they connector to their cards will have this built in as a feature...
