LOOL I didn't know they had a binary up for EQhash lol good one i'll send a donation your ways anyways for the honestly hard to find in this dog eat dog world
also I've been doing some testing with the i7 6800k and with an OC to 3.7 MHz it does around 20h/s on lyra2z , basically double the hash rate of a 6700
I have a feeling I could get more out of it but I tried a higer OC and I didn't see much benift, hash rate acurally went lower /shrug

Thanks.
If higher CPU clock didn't help then your mem bandwidth is maxed out. Did you try to OC the mem?
Not yet but I have XMP set up it should already be OCED I thought
performace actually seems worse with mem oced

I will look at it.
id donate .2 btc myself if you can add it so i cant test it on the zcash test net
I was tempted to copy the Nicehash binaries and offer them to you privately for .2 BTC.
https://github.com/nicehash/nheqminer/releases
First impressions:
I haven't tried the binaries and can't compile on Linux because I have an old version of QT. I don't want to risk breaking my
cpuminer compile environment.
nheqminer is a completely different from cpuminer, all c++, different SW architecture, different build process. Merging it with
cpuminer is not going to happen.
The algo has similar issues as zcoin, it is extremely memory hard so the limiting factor is memory bandwidth, not compute capacity.
It is already acknowledged by Nicehash that 6 threads are all that are needed on a i7, so mem bandwidth is already saturated and
it wouldn't benefit from optimizing.
There are opportunities to promote some SSE4/AVX code to AVX2 but the potential benefits are very limited. The i7 is already I/O bound
so it won't improve with AVX2 (as seen with zcoin) but i5 and I3 may see some improvement. With only 4 threads there may still be some
memory bandwidth available that could be exploited with more efficient code. How much it will help is anyone's guess.
Given the amount of work involved, my lack of experience with qmake and c++, and the limited potential benefit I'm going to pass on it
for the time being.
If anyone wants to pick it up I can help with the intrinsics but it looks pretty straightforward to migrate from AVX to AVX2.

ok this makes no sense :
intel G1820 using cpuminer-core2 is getting 569h or 10h/s
the G3250s using cpuminer-core2 are also getting ss high as 500 h or 9.8 h/s
and a brand new skylarke I-7 600k using cpuminer-core-avx2 is getting a max of 580 hs or 9.9 h/s cores hash faster but max out at aroun 90h
a core i3 4170 using cpuminer-core-avx2 gets only 450 h or 8.9 hs/s - slower hash but each core does 120 h
any ideas as to why the i3 and the skylarke under perform so much on lyra2z

Yes, I have discussed it extensively. It all about memory bandwidth, not compute power. For kicks try reducing the number of threads
on your 6700K until you see the total hashrate drop. Hint: it's less than 4.
At my local store that had some broad well - E cards 6 core ones for only $100 more I exchanged my 6700 for a 6800k are boy were you right , even with like 50% usage on the cores I'm seeing speeds
of like 10000 h and 30 h/s I guess these cards have 28 pc-e lanes vs the normal 16 ? I cant image the higer end ones wit 40 pc-e lanes thoughs could probably do a sold 60 h/s , crazy these are only $100 more than the i7 6700k I did need to buy are more
expensive mb though.
ok maybe this was a fluke after windows 10 updates run seems to have slowed down a ton trying to figure out whats what
**edit no fluke
got the same high hash rates agin but for some reason after a while the miner just stops when it hits those max rates of 9k h or more any ideas ?
seems that the pool kicks the rig off due to shares being such high hash rates ? I get stratum timeouts when it gets to the higher rates
Stratum problems are a pool issue.
Yes I switched to pool.mn but now the hash rates is around 1000h or 17.5 h/s weird though none of my other rigs have stratum issues on suprvova

I've seen wolf reply this: https://gcc.gnu.org/onlinedocs/gcc-6.2.0/gcc/Invoking-GCC.html#Invoking-GCC to someone asking what special flags he use on his zcoin miner (top 3 @ Suprnova) Maybe there's good info for performance optimisation in there..

Wow youre rate basically the same hashrate with 3 cores running, but I notice that shares seem to be submitted slower with less cores
or is that just a display issue ?
basically this CPU is useless for mining this and zcoin which is why I got it what a wast of $299

I think there were errors before this, I need to see the first ones. Also please provide some of the more mundane
info like the version, where you downloaded from and the build commands you used.
Edit: Try uninstalling jansson-devel. It looks like there is a bug in configure that can't handle when jansson is installed
on the system.
without jansson-devel got 1 warning but working, thanks
