miningpoolhub with 40k difficulty is too much for my i5-6000. I switched to pool.mineXMR.com port 4444 fixed diff 20k. It is stable for 30 minutes. 5-6 USD monthly with CPU. I think it is not bad since CPU is %90 times idle.

Four threads ? So it's better to use 4 normal threads than 3 + dualmine ? [heart broken] If that's what you say, so it's another proof the dual mine is useless outside the very rare case of a 2M-cache dual core cpu. Yes, indeed, he is right: 3T => 58 H/s 3T + helper => 64 H/s 4T => 70 H/s And that despite Deneb has only 6 MB L3 cache. But I forgot the special cache architecture of AMD systems. Intel systems have inclusive caches. So the size of the L3 cache is the maximum cacheable size, because the data in L2 and L1 are just subsets of a copy. AMD systems instead have exclusive caches, where no data is ever stored in L2 and L3 at the same time. That's why you can add L2 and L3 cache size. Deneb has 4x 512 KB L2. Together with the 6 MB L3 you get 8 MB cache altogether; or room for 4 threads. But it still can be helpful for non-AES Intel CPUs with limited L3 (Lynnfield) or for Phenom II X6 to use the last two cores, as well

The L3 cache of the G4400 is not big enough for 2 Monero threads. Use just one either or switch to a cryptonight-lite coin like TurtleCoin. Then you can use both cores without flooding the cache.

Dual mine forbidden with AES and Cryptonight Heavy. AES because it's always far worse than regular threads, Heavy because there's no longer smooth parts in cryptonight version Heavy, so threads have no longer any resource to share.
Dual is for non-aes, C-Night[v7], C-Light[v7], 32 or 64 bits.
I was aware of that fact, I tried because my CPU have 16 cores 8 physical 8 logical, if we use for example 4 each the flood cache happens, hash drops, so I thought if the logical shares the phisical core cache maybe it will work, was just a guess no technological knowlage.

There you go
Intel Core i5-6600 Processor - 26.5 watts average - mineXMR.com Monero - 20k difficulty
01:00:28 | Valid Shares found 30 01:00:28 | Total hashes 600000 01:00:28 | Miner uptime 1:00:46
AVG: 166 H/s
This is a nice addition to my current rigs. Free profit from existing hardware.

Still PhenomII X6 have better performance with 6T than 5T+helper, 153 vs 141. Could you please try the following config for your X6; just for interest "cpu_threads_conf" : [ { "cpu_architecture" : "thuban", "affine_to_cpu" : 0, "use_cache" : true }, { "cpu_architecture" : "thuban", "affine_to_cpu" : 1, "use_cache" : true }, { "cpu_architecture" : "thuban", "affine_to_cpu" : 2, "use_cache" : true }, { "cpu_architecture" : "thuban", "affine_to_cpu" : 3, "use_cache" : true, "dual_mine_with": 2 }, { "cpu_architecture" : "thuban", "affine_to_cpu" : 4, "use_cache" : true }, { "cpu_architecture" : "thuban", "affine_to_cpu" : 5, "use_cache" : true, "dual_mine_with": 4 }, ] THEORETICALLY, this must be the fastest config for Phenom II X6 What clock is your X4 running?
Phenom II X4 905e runs at 2500 MHz.

Processor i7 5775c Broadwell on XRM STACK gives ~ 380 h / s. On your miner is ~ 260 h / s Cryptonight V7. Here is the configuration:
[ { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false }, { "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : false },
],
Also your miner, in contrast, for example XMRIG is tied to coins from the list. It is not comfortable. On the XMRIG, the result is about 370 h / s. Remember, these processors generally have an L3 cache. Ryzen did not notice the increase. 1600 @ 3850 XMR Stack = 600+ h / s.

@Mind163 your Broadwell CPU not only has L3 cache, but even L4 cache Thats why XMR-Stak switched to double hash mode (there called "low_power_mode"). This feature JCE is missing so far, but the developer is just working on, if you have read the thread

Hi! I have a 4 x e7-4870 (4 x 10 core + hyperthreading, 30mb cache per cpu) machine. It won't let me set more than 32 threads with the -t command. I've had the machine up to 1400h/s on xmrig, but I just can't seem to get past 830 with this. Please help Straight from download, I get ~300h/s If I set 32 threads, I get about 820h/s.

This feature JCE is missing so far, but the developer is just working on, if you have read the thread I apologize. My native language is russian. It's hard for me to read the whole topic. So I decided to unsubscribe and send a configuration to help the author.

Jce now has a limit of 64 threads, from version 0.21 I have no dual cpu machine with so many cores so I couldn't test real life, but the 32 limit is gone. -t won't let you spawn more threads than cpu detected, on purpose. To go above, use config file.
A copy of the first lines logged, where it detects your cpu, could help.
I've had bad reports about perfs on i7 and other big Intel cpu. I don't own one so I cannot assembly optimize for now. I'm surprised of such a difference, but yeah it may be the lack of dualshare mode.
On ryzen I'm better but the difference is low, about 1% on CN, on v7 I'm about 2.5% faster. I reach 502 on ryzen 1600 while xmrig and stak max at 489

Is it a request? Jce already gives such info when pressing R. Btw, thanks Edit : I should detect L4 (not tested real life, my best cpu is Ryzen with L3) but yeah the perf gap seems to come from that dualshare mode. I'm currently writing the assembly, starting with AES 64 mode. Not sure I'll do a 32 bits code. Not enough registers

Will be equal to physical hashrate on the long term, mathematically after an infinite time Good idea, will be in next version

I note, those coins will be added in next version. I want to check coin for diagnostic and auto fork detection. Otherwise 99% of defect report are because of a typo in wallet or bad fork selected.
