Hashrate on i7-6700K

[Morgon]

I'm running an i7-6700K (4.2 GHz) with 32GB RAM.

XSC suggested running 4 threads - one per each physical core - and I'm hitting between 240-250 H/s, which is about 60 H/s per physical core. Several benchmark sites claim this should be getting 320+.

"cpu_threads_conf" :
[
    { "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 0 },
    { "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 2 },
    { "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 4 },
    { "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 6 },
],

When I change my affinity to add the secondary threads ('odd' cpu numbers), my per-core hashrate sinks (20-30 Hs/thread), overall performance drops (~185 H/s), and my system starts to get unstable.

The sad part is that I'm running XSC on other machines without CPU AES support and getting a higher hashrate. How do I take proper advantage of my hardware? I am using hwlock and I don't seem to have any other errors in relation to the miner.

I have something similar, i7@2.2GHz giving 35-45 H/s per core. Benchmarks say I should get more.

Changing no_prefetch to true has helped quite a bit. Average around 315 with spikes to 325.

I have 10 cpu i7-6700k (stock speed) & 32GB RAM and surprisingly all 9 getting around 355H/s which is more than the suggested hashrate and 1 getting only 320H/s

seems like chip performance though

Hi all not sure if this ever got solved i wanted to share what im getting after some tweaks
