Re: [ANN] cpuminer-opt v3.19.1, open source optimized multi-algo CPU miner
Which argon2 algo should I select to mine TRTL (argon2/chukwav2)?
cpuminer-opt doesn't support that variation of argon2, you need a different miner.
No plans for future support?

Re: [ANN] TeamRedMiner 0.3.8 - CNv8 - Vega 64 2200+h/s Rx470 1025+h/s Low Power Draw
very good miner!my lexa rx550 saphire 2gb elpida memory 575 hash with my custom straps.baffin only 450hash on ethos.why low hashrate baffin?any idea?
We do have a few theories but need to do a separate project to sort it out. It is surprising really. We focused on the lexas this time though, 575 h/s for a 550 2GB is very impressive
.Yes, it's very impressive. For 1 month I was trying to fix the card BIOS and it helps a lot that her memory is Elpida. In Windows with CRYPTONIGHTV7 pi? Anei 550 hash with XMR-Stak 2.4. Respectively the Baffin 570 hash. In Linux the Baffin always had a low hashrate.
What Elpida straps do you use to get that hashrate? I've rx550 baffin 12CU unlocked, gets 520 h/s with 3+3

Mining CryptoNightV8 with the following settings will crash. Do you know the cause?
MSI Radeon RX 470 4G
MSI Radeon RX 470 4G
- Core Voltage -81
- Power Limit -30
- Core Clock 1160
- Mem Clock 2050
Try to increase power limit
My problem is with cryptonight normal v7, my 560s are capped at 540-550 h/s, i'm editing elpida/hynix straps with "some" knowledge but i can never pass the 540 h/s although the memory does that with 1950-2000 mhz, whatever i do to the timings, i cant seem to pass 550 h/s even with core to 1230 mhz (1150 mhz on 16CU 560 and around 1900-2000 mhz silicon lottery on memory, always gives 500-550h/s) I don't get 550s cause they are roughly almost the same cost! and they cnat mine ethereum or ethereum forks even with 4gb of memory cause of the compute limitations.
What memory strap/config do you use for Hynix MJR and Elpida? I'm stuck at 505H/s
Re: [CPU] JCE Miner Cryptonight/forks, brand new, super fast!
impressive tip from robminer80 who gives better advices than the dev !
Probably thanks to the repartition on cores 1 and 3
I postpone 0.29d to make more tests and add coin BLOC (another CN-Heavy coin)

Apu's L2 cache is 2MB + 2MB in two modules, Cpu 0 and 1 have access to the first 2MB, Cpu 2 and 3 to the other 2MB
Re: [CPU] JCE Miner Cryptonight/forks, brand new, super fast!
thanks for the test, it seems my autoconfig is bad on the A10, it allocates too many threads. I'll fix it, thanks.
The multihash (double hash is the 2-case, you can set from 1- to 6- ) is also called low-power in stak IIRC. It's about using, on one CPU core, twice the register and twice the cache to get sometimes twice the speed. The trick is that it let the other cores free, so it consume less power and allows the Turbo to enable, for CPU with turbo.
Technically, it's good, sure when you want to save power, but also when you run out of cores and not of cache. If you have a CPU with 2 cores but 8M cache, normal config would give only 2x2M = 4M cache used.
you may enable double-hash to use 2x2x2M cache = 8M of cache, and get some extra perf.
It works more or less depending on the CPU. It's very efficient on Ryzen, and not at all on Core2.
I looked closer at the A10, and yeah that's a little APU with little cache.
I give you an experimental config that could let you get some extra perf, but not sure, i cannot test, i've no A10.
"cpu_threads_conf" :
[
{ "cpu_architecture" : "auto", "affine_to_cpu" : 0, "use_cache" : true },
{ "cpu_architecture" : "auto", "affine_to_cpu" : 1, "use_cache" : false },

now finishing 0.29c, the last CPU-only version, with some updates.

Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v11.7 (Windows/Linux)
I've reached 15.758 MH with overclocking and undervolting with ease and no problem.
I've a rx560 Hynix too, which timingstraps/clocks do you use to get 15.8MH? I can't reach 15
So I have an I5 3570k (Overclocked to 4.4 GHZ)
32gb 1400mhz ddr3 ram (Possibly only 1333, but it should all be matching modules)
and for whatever reason, I can only mine 80-100 h/s
For comparison, I also have an i5 2500k running at 3.4GHZ that is getting 180-200
16gb 1600mhz ddr3
It's not thermals (I'm at about 60C on hottest core)
and task manager says its getting about 80% of the CPU (roughly the same % on both computers)
Win 10 with winMiner
I was just curious if anyone might be able to narrow down the root cause of this slowdown. I'm not looking for a lecture on the unprofitability of CPU mining (I don't intend to mine with them, I just got winMiner and thought I would try it out for curiosity)

You'd use 3 threads (trying no affinity or affinity on cores 1,2,3 leaving 0), check in bios if ram interleaving is ON, clock ddr3 and timings as much as possible (your 2500k has 1600mhz ram
)I use:
AMD A10 6300 @ stock clock, 3 out of 4 cores mining XMR @ 45-47H/s with Claymore_Old on MinerGate pool.
You'd have better cpu hashrate on XMR with 2 core setting affinity to cores 1 & 3
Hi! guys I don't know if these specs will make me profitable . I just wanna know if there somebody can tell me what is my hash rate using this computer ( specs ) . I wanna try to mine ETN

With your config you can try mining cryptonight coins using Xmr-stak with this settings: CPU using 2 threads affinity core 1-3; Gpu 2 threads Intensity 112 each, affinity core 1-3.
Overclock DDR3 if you can. You could reach =>250H/s with 2133-2400Mhz ram.
Re: Gateless Gate Sharp 1.2.17: Fastest AMD NeoScrypt Miner, ETH dual, CryptoNight
@zawawa
Can you make possible separate mining for each gpu? For example:
-GPU1 mines cryptonight on Nicehash
-GPU2 mines ethash on Ethermine
and so on...

Re: PhoenixMiner 2.5d: fastest Ethereum/Ethash miner with lowest devfee (Windows)
Been using this miner for like 6 hours now and it's amazing. 4-5 MH/s more than Claymore, which is great!
But I'm having this weird problem right now, I have 2x RX560's which are getting 14.7 MH/s each, but every ~10 seconds they both drop to ~12 MH/s for 2 seconds and then it goes back to 14.7 MH/s. My RX580's are not doing this and are keeping strong on the 30.5 MH/s mark. With Claymore I do not have this issue, I also tested this with Ethminer and the RX560's do not drop in hashrate at all.
Would be great if you could get that fixed somehow, other than that, this miner simply amazes me, keep up the good work!

Same here,wait for fix.
Please pay attention to this, 2.6 goes worse...
Re: [ANN]: cpuminer-opt v3.8.0, open source optimized multi-algo CPU miner
Could you update Windows compilation instructions?
A better way was found but it is compiled on Linux for Windows. This isn't practical for Windows usersas they would need Linux as well.
Unfortunately there is no good solution at this time for Windows users to compile from source..
I actually use the cross compile procedure on Ubuntu shell in Windows 10.
But it still does require some basic linux knowledge
Can you tell me how to?
Re: [ANN]: cpuminer-opt v3.8.0, open source optimized multi-algo CPU miner

Can you be more specific? The documented procedure is the one that works to compile on Wndows
for Windows. It's old but is the only one I've found that works.

That procedure results in use old version of GCC (I tried to update it with no luck, build not works). I need to compile march native for Kaveri architecture. In XMRig (for example) I have 10% boost on precompiled version and 20% boost compared to cpuminer-opt using cryptonight and cryptonight-lite algo.
