      If someone hands you a 7990, please don’t do the same overclock till burnout test… lol

      Lol i wouldnt do it with a 7990, and the overclock was stable, just the vrms weren’t up to the job lol

      If i had a 7990 id probably look into watercooling :P

      The R7 240 temps stayed pretty low even at 1.4v, only just above 70c, its designed for 35w TDP, i unlocked it to 75 in the bios, and overclocked the clappers off it, it *seemed* alright xD

          -e, --engine=N choose a NeoScrypt hashing engine
          0 integer (default)
          1 SSE2
          2 SSE2 4-way

          I was not aware of different ‘engines’ for hashing on CPU’s as I don’t CPU mine. What is the reason for them?

              What is sse2?

              It’s an instruction set for CPU’s, pretty much all cpus nowadays have at least SSE2, even my 7 year old laptop (from core 2 duo era) has SSE3

                    I tested the miner on my laptop (Pentium T4400 @ 2.2GHz):

                    INT: appears to be the old engine (gets same hashrate etc), 4.4kh/s

                    SSE2: a little bit faster, causes my laptop to heat up a lot more, 4.8kh/s

                    SSE2-4way: even faster, not as hot as SSE2, 5.8kh/s

                    Also on my desktop (i7-3770K @ 4.0GHz):

                    INT: again appears default, 27kh/s

                    SSE2: not much improvement, 28kh/s

                    SSE2-4way: a bit better, 31kh/s

                    it seems that the sse2 and sse2-4way engines helps alot with older cpus which do not have as much number crunching power

                      Thanks GhostLander!WoW! I had never seen a CPU hash faster than a GPU!

                      By the way, why do old graphics cards hash so badly with neominers? I have a 5970 (and everybody knows it is not a bad one) and it can barely reach 26 kh/s with two cores. Is there hope that this will be fixed?

                        Worked great here for me once I understood the flag setup to use. I saw about the same results as was posted earlier.

                        Great work! Thank you!
