      ############### Update ###############

      API page working!

      All entries info: http://hw.neoscrypt…gethardwarelist

      Individual entries: http://hw.neoscrypt…ualhardware&id= where is the entry_id found within gethardwarelist

      Search entries: http://hw.neoscrypt…rdware&qstring= where is your query (e.g “HD 5870”), the search is fulltext, and will pull any entries containing any of the search terms, and will order them with highest relevancy first.

      Currently the output is formatted in pretty json mode with

       tag.

      This will be changed back to block text json once i have written a guide page for it.

      ############### Thanks ###############

        Thanks, i will add this entry now, just got home from athletics competition, did shit, as ive just started getting back from illness, but its a start :)

        It seems theres a HUGE difference between wolf0 and normal kernel for amd cards with sgminer, with nvidia cards, it seems its pot luck whether sgminer actually works, and if it does work, its hard to get it working at any speed comparable to cgminer.

        seems sgminer + wolf0’s kernel is best for AMD,

        and cgminer + wolf0’s kernel is best for nVidia,

        i did get my i7’s HD 4000 running with cgminer pretty well, and it actually did produce an alright hashrate (11.68kh/s @ 1700MHz) and gave about same h/w as a 750Ti, i did not test with sgminer unfortunately, which perhaps i should have tried, ohwell maybe another time

        i hope a cudaminer for neoscrypt is released, as it would probably boost performance and efficiency on nvidia cards by alot, we all know nvidias opencl performance is pretty damn poor, but cuda actually is not that bad, cuda with scrypt gave me 350kh/s on a 660Ti, whereas using cgminer i got around 65kh/s, big difference!

        anyway thanks for the submission

          Hey Spartan. No idea about power + screen shots are a bit impractical but here’s all the relevant info.

          Type: GPU
          Hashrate: 254.1 Kh/s
          Vendor: AMD HD 7950
          Model Specific: XFX Double D FX-795A-TDJC
          Est. Power: n/a
          Miner: sgminer-5-dev-neoscrypt
          -rI 4584 -w 64 77c

          Extra info: Shaders: 1972, Core Clock: 800, Mem Size: 3072, Mem Clock: 1250, Mem Type: GDDR5, Bus Width: 384 bit, Mem Datarates: 240 GB/s

          Notes: Raw intensity gives me the best results by far. -rI 4584 is my sweet spot. Any deviation above or below that gives reduced hashrates.

          Important! Using **Wolf0’**s kernel is the biggest single factor in getting optimum hashrates.

          Thanks for the heads up on RL. Changing from I 15 to your RL 4584 added 30Kh/s to my XFX 7950!

          Hashrate: 216.91 Kh/s (12-hr Avg)
          Model: XFX Core FX-795A-TNFC
          Est. Power: 200-215w
          Miner: sgminer-5-dev-neoscrypt
          -rI 4584 -w 64 79c

          Shaders: 1792,
          Core Clock: 980,
          Mem Size: 3072,
          Mem Clock: 1375,
          Mem Type: GDDR5,
          Bus Width: 384 bit

          +1 for Wolfs kernel. Took this card from 78kh/s to 200+ Kh/s.

            Wolf’s kernel took my 290’s from 70 to 330, and my 290x’s from 70 to 302… (%^@$^ Elpida memory)

              Will get this added asap, having a few delays with stuff, usual festive stuff with family and being unable to access a fully working pc to actually do things on

              Recently tested an R7 240 (its pointless dont try)

              Got the core clock to 1300 MHz (default 780), and the memory from 800 to 1300 also (tried upping the voltage from 1.15v all the way up to 1.4v but still couldnt push past that 1300mhz), huge boost in hashrate, from around 12kh/s to about 20 kh/s, this didnt last long sadly as the cards VRMs blew after just 3 days, poor thing, ohwell was a free gpu :D

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

                  You can bump the sapphire R9 290 Tri-x OC up from 333 to 340… The GPU’s came back from warranty replacement, and can get the juice cranked up a little with fans that aren’t failing…

                    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?

                            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!
