i just did extended mem testing all night over 8 hours, plus basic and standard testing, all no errors.
and frankly, i never never get any blue screen here which is usually RAM, since i installed this and i have a high performance Ram.
yeah you are right, you are like Sherlock Holmes hehe looks like i had that problem before.
and no, i am on Win10 64x.
only thing i can think of is that i have BTC core on ext usb 3.1 SSD drive (at that time it was not SSD tho). this one is faster now.
