Your miner with CN-heavy is solid ! I have better hashrate on 24avg than cnv7 !
Speed of heavy algo on 8Gb+ cards allways faster than on V7. It's normal. I thought it was 1,5KH/s on CN Heavy (Vega 56/64) and 2K/s on V7. ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Vegas took a hit. RX4/5XX 8Gb got a 5-10% bump from heavy.

I don't know it's a bug or not!my miner work find on cn-saber with 8K,but after a disconnected from pool and reconnected again,the hashrade drop to about 7300 and won't restore to 8K,i have to restart the miner to get 8K again... here is the log

You can see a Connection interrupted and reconnect at 05:04:11, then the hashrade drop to about 7.3K!This happend on all of my miners so i think i have to report this!

it's known issue for Heavy variant after reconnecting JCE not doing warm up again. what I do is put watchdog and if miner close then restart rig.

Hi JCE, i updated my 3 Rigs to JCE Miner. It works great, effective hash increase, but i have a problem. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Ffs1.directupload.net%2Fimages%2F181008%2Ftemp%2F45d2llir.jpg&t=665&c=FjQZg1ybPtRwEw) At around 3:30 o´clock all 3 rigs deliver stale shares for around 1.5 hours, 5 days in a row. Other people in this pool don´t have this problem, other miner (for example SRB) don´t have this problem. If it is on 1 Rig then i say ok to much OC, but 3 realy different rigs with different cards and different drivers make the same problem? i think it is a jce miner problem. A Ryzen R5 1600 delivers also stales shares and with the older version 0.32m it works. I use jce 0.32q at the moment. Any solution or other guys with this problem? JCE there is a problem in your code or something like this. Rig1 with JCE 0.32q mining on nanopool normal port -> all fine Rig2 with SRB 1.6.7 mining on nanopool ssl port -> all fine Rig3 wtih JCE 0.32q mining on nanopool ssl port -> from 3:30 to around 5 o´clock only stale shares, tested 3 days in a row Test GPU with JCE 0.32q mining on nanopool ssl port -> from 3:30 to around 5 o´clock only stale shares, tested 3 days in a row

Maybe nanopool did something with ssl port in your pointed time?

Hi all!
Again I do very little support, i'm focusing on the v8 assembly. I've one that works, but i'm not satisfied with the performance yet, so i need to improve it. If i'm really stuck, i'll write some parts in C and rewrite to ASM later. I also need to keep room for the tests. I'll skip the formal performance benchmark against other miners like I did for V7 in april, i just have no time.
About the hashrate drop every 24h: i still did a quick review of my netcode, and really found nothing with a 24h period. Could it be some bottleneck with your wifi or ISP? The fee session period is ~100 mn, like Claymore or SRB, but really not 24h. Also, stale shares are amplified by a high ping, hence why i suspect your network. The symptom may not arise on other miner because we have different stale share aggressivity, JCE is mid-high aggressive while Claymore is smooth, so this latter provides a lower effective hashrate, but is less sensitive to bad ping.
Bad warmup: yeah it's a known problem, but can by avoided with a combination of Watchdog and script (.bat) that restarts the miner in case of disconnect that makes it slower. Also the option -q quits the miner at first network problem, it can be used in place of the watchdog, or even both. Since JCE starts in a few seconds now, it's an convinient workaround.
What's sad is that is would be very simple to re-trigger the warmup after a disconnect in my netcode, just that v8 forks eats all my dev time.

My CPU code is now ready, version 0.33a to be released soon, with: Monero-v8 (enabled by default for XMR and WOW), that's --variation 15 32-bits and 64-bits support Windows and Linux Fix a bug that could make high multi_hash (x4 to x6) produce bad shares on Electroneum. More shitcoins (Tritanium, Zelerius, HospitalCoin, PyrexCoin)
Now entering test phase, planned release in less than 24h hours Threadripper 1920X Your config lacks some multihash, with 32M cache and 24 logical cores, you can achieve more performance. For monero, enable 16 threads, on logical CPUs: 0, 1, 2, 4, 6, 8, 10, 11, 12, 13, 14, 16, 18, 20, 22, 23 For aeon, AMD cpu are more complicated, enable all logical CPU as you did, plus turn some as multi_hash:2 try turning 0 and 12, and if you get more perf, also try 6 and 18, then also 3 and 15, and finally 9 and 21

Some times miner say "low difficulty share" and "rejected by pool"
my setting
jce_cn_gpu_miner64.exe --auto --any --no-cpu --forever --variation 12 --low -o %POOL%:%PORT% -u %WALLET% -p %PASSWORD% %SSL% %*
in other miner programs, there is no such problem
exp: SRB Miner
whats wrong ?

whats wrong ? Are there messages before the reject that say "stale share, may be rejected by the pool" ? If yes, so here's the answer. We all have different netcode aggresivity about stale shares, it's very possible JCE is more aggressive than other, like Claymore or SRB. Please look at your pool to see if your effective hashrate is better with JCE, even with the rejecteed shares, if yes, so it's still a good deal for you. Also try to lower the multi_hash parameter, it sometimes helps, but may also make the miner slower, so do the math if it worth to be changed. CPU version to be released very soon, i'm testing it right now. GPU will come next.

Thanks. i get lower hashrate with that 16 core config as below on xmr (~750). Perhaps due to dual channel ram. { "cpu_architecture" : "auto", "affine_to_cpu" : 0, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 1, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 2, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 4, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 6, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 8, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 10, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 11, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 12, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 13, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 14, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 16, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 18, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 20, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 22, "use_cache" : true }, { "cpu_architecture" : "auto", "affine_to_cpu" : 23, "use_cache" : true },
for cn-lite I already have enabled all logical cores and multi_hash:2 for 4 core; 0,6,12,18

Check the github for suggestion with your card.

Hi! The Windows Monero v8 CPU version is out!https://github.com/jceminer/cn_cpu_minerversion 0.33a I expect it to be the very fastest on 32-bits and non-aes, and in a lesser extent in 64-bits AES, the major assembly. The Linux build comes next, then i focus on GPU, i'm getting very late now. I read the report about the bad OpenCL. JCE openCL is generated, unlike SRB which is precompiled or stak which is static. It allows wider optim support but in case of failed build, which is very possible with generated code, please give the GPU detection log that is displayed at start, so at least i know what GPU you use. I tested the current code (the future v8-capable) on AMD HD7000, RX, Vega and even Intel Graphics, and it compiles. I expect the failure to be caused by a different GPU or different driver version that i tested on. However i still do very little support for now, must stay on the v8 support. edit: The Linux Monero v8 CPU version is out too!

I'm doing it right now. I'll first provide a simple implementation based on the on from the official Monero team, then i'll optimize. It will also contain a little optim for Heavy/Tube (unrelated to v8, just i'll release it at the same time). If you wonder why it took so long just to make the CPU version, so that's because 1. v8 is completely different from v7, i couldn't reuse anything but the implode/explode parts 2. I support 32-bits, and the 32-bits version was hell to make, because i run out of registers everywhere 3. Every x1 to x6 multihash has it own assenbly 4. the uncached version adds two more (for 64 and 32) 5. each time, there are specialization for some CPUs like core2, nehalem or ryzen so that was about one hundred asm to update, bench and test ![Cry](https://bitcointalk.org/Smileys/default/cry.gif)

Just 1 simple question regarding v8 algo setting.
Will it have the same intensity, workload, etc on Vega?
Thanks

Probably not.
First, it will consume more power. I've even burnt one of my PSU during my tests, because my already power-hungry HD7950 pulled a lot more power when mining v8. So, if like me, you have ultra-fine tuned overclock and PSU, better redo all your tuning as if it was your first rig. v8 is very different.
v8 was obviously made to run fine on AES x64 cpu (because all steps are one-instruction there) and run not fine on GPU, because it involves steps GPU are bad on, typically division and random memory reads. Don't forget a GPU has something like 8G of strachpad and only 512K or 1M or 2M of cache, so all accesses are virtually uncached, and verrrryyy slow.
GPU are good to blit 128M of textures in a row, not to random access chunks of 16 bytes. That's what make CN (and still more CN-v8) CPU friendly, and GPU resistant.

So, when I use auto config, how much is the intensity you set on Vega?
