Yes, sure, 520 H/s on 65w sounds a terrible deal, but, hey, that's how idiots work.
Anyway, I do mine Cryptonight Lite with Ryzen, you get almost 4x the hashrate with same power consumption.
But do tell me how to get 400 H/s on a Xeon e5645 stock, that's the first time I hear it.
200 is more like it....
Perhaps you're running 12 threads and trashing the cache?
If so, try limiting it to 6 threads instead of 12.
No, 6 threads only (12 Mb Cache)
Here is my cpu.txt
"cpu_threads_conf" :
[
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 2 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 4 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 6 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 8 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 10 },
],
But what I get is what I see reported for Xeon e5645 on Cryptonight. It's an old CPU, but it support AES, with 6 cores and 12 Mb L3 cache one should expect higher performance. It was a disappointment.
