Hi @JCE-Miner!

I'm very very satisfied with JCE + Ryzen 5 1600 + Windows. Pretty high hashrate (1900~2000H/s mining CN-Lite). But I'm using HiveOS to mine some coins that doesn't have good miners for Windows. And in the HiveOS I don't have the marvelous JCE-Miner.

I know a version for Linux, but I couldn't create a custom miner. Can you make a integrated version for HiveOS?
Guidelines are here: https://github.com/minershive/hiveos-linux/blob/master/hive/custom/README.md
Some miners packed already: http://download.hiveos.farm/custom/

Thanks in advance!

For the new version;
I wanted to change the coin i was mining for 7-8 days to another profitable one but with the fcking version..
- when you refresh the page you need to login again(what a stupid thing!)
- more complicated than previous one (didn't like it)
- I changed the wallet (which was used by me and it was saved by me before the previous version) but it is not working. ANd you cant change it.
- When i create a new wallet it doesnt shnown "Flight Sheets"
- When i tried to delete a wallet it says "one of Flight Sheets uses bla bla"

And the result 2 of my rigs are not mining anything now and i passed to windows again !

You want for this shit $15 by month? F.ck OFF.


Yup. I have the same login-every-refresh-every-page issue.

Hi Doc!

I'll play with algo switching. It's nice to see it integrated in your SRB.

I have a little question: The "GPU-Z trick" for heavy/haven mining still needed? Or is there another way to stick hashrate at max? I hadn't needed it before, but now my 470 8GB fluctuates between 889 and 1000H/s, its pretty high variation.

Thanks in advance. Fastest miner ever Cheesy

About my lastest tests:

- Tried SEQ-MISQ1 and CAS from 1500 strap. Mining doesn't starts, bsod after closing miner.

for Deep diving though need to mod a 1625 or 1750 since base tCL is 19, thus 20 when you +1
If your elpida crashes at 1950 with whatever timings, that's similar to mine, whether solder/bga issue or power problems.


Now i fully understand the MR0 ,MR8 etc but the DAMN Binary bits relation to the 4 Hex characters! omg.
I think finally I reached my goal.

My memories are not Elpida, but Micron (not Micron-Elpida). BGA are not a problem, the ex-owner has 4 another cards the same model, and all are bad for memory overclock.

I changed MISC8 to 1500 base, lowered TRP_WRA a little and bumped tRP. To improve hashrate, I did RASMACT fine tuning (yeah, the "trial and error" way). Nice results. For now, 971H/s at 1200/1900. I think we have a "mission complete" for Micron, better than expected results, with much knowledge that can be used to improve Elpida and Samsung.

Elpida RX570 4GB is runing at 1200/2020. 985H/s. I think there is room for improvement over 1KH/s. Maybe getting closer to Samsung (at least in v7) Cheesy

I find it really strange that your max memory closk is that low, look how high my micron goes on RX560:

https://bitcointalk.org/index.php?topic=3052745.0


BTW, does anyone have working, stable straps for Hynix and Micron with TRRD=5? Seems Elpida has least problems with it


Me too. But maybe the issue is memory cooling. When the weather is cold, memory can run at higher clock. When temperature rises at 35C+, run at 2000 is a pain.

Quote from: QuirkSilver
Elpida is hilariously funny, glad i started learning with it, no rules (almost!) , so for example for most eplidas an easy solution for low frequency memory (will get hotter though/unstable) try dropping trrd to 4 on the one click strap or SRB bios editior's pimped strap and loosening reads slightly increasing tRFC substantially (thanks to Kueto again who helped with this!) it gives you more stability for negligible speed loss, clock memory to 1875-2025 however, most non cooled memory, will give errors above 1900, still will give 545 h/s -585 h/s (560, will be 1000 h/s++ for 570/80)

Yep. No rules. I'm tuning my RX570 Strix 4GB Elpida, and the Micron techniques are useless lol

1250 core should bump it over 1k.
Yes, but my RX570 is bad for core OC. At 1250 it needs around 975mv. Power consumption rose greatly. 1150~1200 often is the sweet spot. In opposite, my RX580 8GB Samsung runs at 1310 with 940mv rock solid <3

in addition, is good to improve by memory optimisation because when OC'ing core the performance gains will be greater Smiley

Good news i done it  Cheesy

Now what about OC settings for my Sapphire RX 580 Nitro+ rig?

What should be those settings?

Core Clock (Mhz):
Core State (Index):
Core Voltage (mV):
Memory Clock (Mhz):
Mem State (Index):

Try this :
Core Clock (Mhz): 1270
Core State (Index): 3
Core Voltage (mV): 930~940
Memory Clock (Mhz): 300 (or 600 if you notice some hashdrop)
Mem State (Index): leave empty

Why we need to decrease the mem. clock ?
Lyra2z isn't a memory-bound algorithm, so reducing memory you can save some power.

I'm quite confused, but knew how it works from the Jedec212 document. I can't set tCL to 20 or 21 to this garbage Hynix AJR even Hynix MJR straps are hilariously made as if hynix is trolling people not to have a soft spot for mining, MJR have 1750 strap (19 CAS) and behold the one next to it is (23 CAS) lol, because cryptonight is affected by writes, both WR, WL are in that MR0 binary inside the damn SEQ-MISC-1.
I tried to borrow straps from other vendors, but the tCKE parameters are different, not sure what excatly would work, then again have to experiment alot. So i rather find that CAS latency.
The lower frequency, i managed to squeeze 975 h/s from that (damaged elpida 570) @1860mhz surely with a tight 1425 strap didn't even hone it correctly though.

Hashrate 1 MHash/s
 Algorithm CryptoNote
 Manufacturer MSI
 Power Consumption
 Core Clock 1257 MHz
 Memory Clock 2000 MHz


The MSI Radeon RX 580 provides hashrate of 1 MHash/s for CryptoNote at Coreclock 1257 MHz and Memoryclock 2000 MHz.


 Gpu Specs

The AMD Radeon RX 580 is a graphics card by AMD. It comes with GDDR5 memory and has 256 bit memory interface or bus width.

Inside Radeon RX 580 there is an Polaris 20 graphics processor chip which has 2304 shaders. The base operating core clock speed of Radeon RX 580 is 1257 MHz and memory clock speed is 2000 MHz.


https://miningchamp.com/gpus/266/Sapphire-Radeon-RX-580-hashrate
A RX580 can mine cryptonight at 800H/s ~ 1050H/s (so, at 1,05KH/s). The hashrate varies depending:
1- The memory manufacter (Elpida, Samsung, Hynix, Micron)
2- The strap/OC
3- Driver (eg. Compute Mode disabled, old driver)
4- Miner/configuration

Any 580 can reach 900H/s+ with proper biosmod. But I really don't know what miner Nicehash is using to Cryptonight mining.

Lavritar, apologies for the abbreviation mistakes, i was writing quickly during night shift. the RASMACT timings are to compensate for having mixed strap i can't fully understand this, but you do that when you get the CAS timings (along with SEQ-MISC-1!!) from a higher strap, but drop tRC for cryptonight, the RASMACT is to compensate (again i'm not sure) when you do this, the equation isn't necessary, at least as long as the sum of rasmac+actr is in the higher than tCR side of course.
don't change tCRCWL, bump tfaw32 to 4 or 6 at least to try.
Nice. That information is useful. You don't need any apologies, your post helped me a lot.

tFAW32 is bumped to 4. No performance penalty. I'll try 6. About the CAS/SEQ-MISC-1 while we can't understand/decode, the best way to optimize is mix default timings for lower straps (to increase performance per clock) oh higher straps (to increase overclockability). Didn't Nerdralph's tool worked for you? (you mentioned some posts before).

Increasing RASMACACTWR to 69 and RASMACACTRD to 55 gaves me extra 20H/s. So, at 1150/1900 the RX470 is mining atr 938H/s. Yep, lowering tRC to 60 and TRCDW(A) to 13 gives me extra 4H/s, but I think the stability cost dont worth it.

Increasing RASMACACTWR in Elpida strap gaves me some hashes too. 946H/s at 1150/2020. It wasn't the goal, but good to see the Polaris shining. Nice Cheesy

Some don't clock as high as others do.  I have couple of cards that don't go above 1950 without causing lots of memory errors and eventually crashing.  
The core on these cards need higher voltage and the cooler isn't good on these cards either which makes it even worse for stability.  Both cards are from same batch so it might be just that.
MSI Armor RX470?
I really don't like the construction. Appears to be a board with 5cm of useless PCB just to make it bigger. Without it, the size would be compatible with a RX460.

Same as mine that goes up to 2300...but to go that high, cooling should be made
in such way that metal plate covers not only GPU, but memory, too (and replacing
usually bad factory thermal paste with quality one)

However, 2100 should be easy to achieve

Also, important is to find sweet spot between voltage and temperature (voltage increase
improves stability, but only up to the point where increased heat starts to be a problem)
I bought it from a miner, so it came with some thermalpads and a good biosmod, but not all ICs are cooled (only 5/8) because the other three arent in the cooler contact area. I ordered some heatsinks at Aliexpress but it will take a little time to arrive (3 months. Yeah, Brazil's mail is poor).

About the memory strap: The board came to me with Matthev timing. I tried many timings (heavyarms, yours, some for anorak's) and the original one (matthev) was best (at least at 1900~2000 clocks). I did some changes/tests and for now I have it:
777000000000000022CC1C00CE615C41C0571016B30CD50900400700140514207A8900A00300000 010122F3F9D2C3617

Is there a way to improve "performance per clock" for Cryptonight? (considering that it couldn't run at 2000+)
i do use thermal pads (these are quite good) https://www.aliexpress.com/item/ARSYLID-High-quality-100-200-1-0-2-0-4-5mm-Thermal-conductivity-3-6W-CPU/32835108024.html?spm=a2g0s.9042311.0.0.4fd54c4d3E82Yb
0.5 mm or 1 mm and a copper shim, 1 mm thick or more https://www.aliexpress.com/item/20-pcs-15mmx15mm-0-3mm-0-4mm-0-5mm-0-6mm-0-8mm-1mm-Heatsink-Copper/32826278552.html?spm=a2g0s.9042311.0.0.3dbd4c4dpaqYyI
I experiment with the thicknesses so that the stock heatsink presses the shim and the pad slightly without being thicker than the processor height (been there done that, and the GPU fan was squealing Smiley ) the more spacious the copper shims the better, however, i do this on rough estimates, that the memory die consumes 1-2 watts each (reasonable?) the shims not touching the aluminum directly is not a big problem, because copper blown by the gpu fan imho is more than sufficient to cool the memory. Most of the Aorus 580s i have memory cooled from the factory reach 2100-2200mhz (8 gb, 4gb all of them hynix) i found thermal pads being 0.5 mm and perfectly matched with the heatsink, but, as a consequence of mining these pads will dry within months (become brittle)

Do you really clock those elpidas to these clocks? lol? how do you cool them? what sort of timings for such clocks!?
Isn't Elpida memories, but Micron. Micron sometimes can be overclocked above 2100 (Branko's 560 can handle this)

I bought these ones (0.5mm): https://www.aliexpress.com/item/20-pcs-15mmx15mm-0-3mm-0-4mm-0-5mm-0-6mm-0-8mm-1mm-Heatsink-Copper/32826278552.html?spm=a2g0s.9042311.0.0.5311b90arAsvdv

2- tCR of the stock strap, needs to be loosened, its tied to tCL, tRCDR,tRP, tRRD are tied to tCR (not tRP in elpida, thats why you can have a very low tCR value) so any +1/-1 to any of those, must be subsequently, done tCR value.
example,
tcrdr 23, tRRD 7,tCL 18, tRP 22 tCR=68
trcdr 24 (+1), tRRD 6 (-1), tCL 18, tRP 22 tCR= (68)
tCR=68 should be tRC?

Here I'm with this:
TCRDR(A) 24, tRRD 6, tCL 22, tRP 20, tRC 65 (tried to low tCL to 20, but didn't worked)
24 + 5 + 22 + 20 = 71. So I would have to bump tRC to 71?

Quote from: QuirkSilver
3-RASMACTRD,RASMACTWR are tied to ACTRD and ACTWR by the rule, RASMACTRD(/W) + ACTRD(/W)= tCR+1 (check any stock strap, same thing) so when you drop writes (-actwr) you should increase RASMACTWR
Yep, I see some gains by loosening RASMACTWR.
870H/s at 50
917H/s at 63
921H/s at 66

But the formula you gave didn't fit here (or I dont understood):
ACTWR (18) + best RASMACTWR (66) = 84
tRC (65) + 1 = 66

Quote from: QuirkSilver
4- Raw Precharge time, tRP must be higher than tCL, it doesnt affect Cryptonight much so its one of the keys to attain high stable straps (by loosening it)
5-loosening tCL is the key to get a higher strap, but now that's the biggest problem, tCL in elpida isn't tied to tCR (that's why you see that one click strap, being good with a low tRC), however, CAS timings (tCL,W2R,R2W) are linked to SEQ-MISC-1
If you changed the tCL of the 1625 strap to the 1750 one without the SEQ-MISC-1 of the 1750 one, will end in BSODs or similar.
Micron one click, took, Elpida's 1500mhz strap and mixed it, so higher tCL mainly, and that works..
Nice!
tRP is at 20, tCL at 22. So I will try it at 22 or 23.

The 5th tip is intersting. Maybe the issue with tCL at 20 (I tried it today) can be linked with it. I will see the strap and find where tCL 20 are, and copy SEC-MISC-1.

Quote from: QuirkSilver
6-increase tRFC substantially, have minimal impact on CN speeds, but gives more stability (+25% or whatever, noticed no real rules here.)
tRFC is a controverse timing. It gives pain while overclocking memories since DDR2 ;p

About looseining it: considering I can't go above 2000 for while (maybe because memory cooling, maybe because the shitty ICs) lowering tRFC (from 157 to 129) was a solution to gain some hashes (around 10H/s at 1900).

Quote from: Branko
Micron and micron-elpida are quite a different story, both in timings and max clock.

Also, your estimate about memory chips power consumption is way too low,

"RX 480 uses 40-50W for its 8GB"

Source:

https://www.gamersnexus.net/guides/3032-vega-56-cost-of-hbm2-and-necessity-to-use-it

So for 8GB cards almost half the consumption goes to memory chips
Holy feijoada!

I don't understand why it comes to us without proper cooling, because it needs. Unafortunately lowering voltage needs hardware mods (could help sometimes).


I really want to thank you three for all knowledge! You are awesome!

If its micron -60 variant (have it in GARBAGE 560D by sapphire, 14 CU even 52% asic quality, even unlocked to 16 CU asic goes to nearly 50%) But at least in that 560D its stated that its a 1500mhz memory... still, the one click strap does 500-512 h/s and maximises at around 1925-1950 with occasional errors, i did mod one of them with thermal pads +a copper shim not much expected though... sometimes the case might be factory overclock "maybe" then your 470 comes with 1750 mhz out of the box, but will never pass 1900-2000mhz

Apparently is a Micron -70 variant. It runs at 1900 with zero errors. I'm trying to improve performance per clock and after I will try to find the sweet spot between 1900 and 2000.

D9SXD. Apparently is a 7Gbps IC



Same as mine that goes up to 2300...but to go that high, cooling should be made
in such way that metal plate covers not only GPU, but memory, too (and replacing
usually bad factory thermal paste with quality one)

However, 2100 should be easy to achieve

Also, important is to find sweet spot between voltage and temperature (voltage increase
improves stability, but only up to the point where increased heat starts to be a problem)
I bought it from a miner, so it came with some thermalpads and a good biosmod, but not all ICs are cooled (only 5/8) because the other three arent in the cooler contact area. I ordered some heatsinks at Aliexpress but it will take a little time to arrive (3 months. Yeah, Brazil's mail is poor).

About the memory strap: The board came to me with Matthev timing. I tried many timings (heavyarms, yours, some for anorak's) and the original one (matthev) was best (at least at 1900~2000 clocks). I did some changes/tests and for now I have it:
777000000000000022CC1C00CE615C41C0571016B30CD50900400700140514207A8900A00300000 010122F3F9D2C3617

Is there a way to improve "performance per clock" for Cryptonight? (considering that it couldn't run at 2000+)

Some don't clock as high as others do.  I have couple of cards that don't go above 1950 without causing lots of memory errors and eventually crashing.  
The core on these cards need higher voltage and the cooler isn't good on these cards either which makes it even worse for stability.  Both cards are from same batch so it might be just that.
Well, I did some "cherry-picking" with your, Branko and PBE straps and I'm getting 918H/s at 1150/1900 in V7. Well, it's greater than PBE one.

My last custom strap is there: 777000000000000022CC1C00CE615C41C0571016B30C150800408700140514207A8900A00300000 010122F3F812C3617
ACT/RASMAC/RD/WR/TRC from Ubermix/Heavyarms
tRFC from Branko
tRCRD/A and TRCDW/A and base from Matthev
tRRD from PBE.
tFAW32 increased to 4 (more stability with no negative performance issues)

MISC values from Samsung's Ubermix gives me BSOD before run miner. I'll try other values.

Well, Samsung, Elpida, Hynix, all of them is fine.

But I bought a RX470 that is making me to lose the hair (lol). Apparently it comes with a Micron low clock ICs. It doesn't run at 2000+ even with loose timings. With reasonable timings, I can run without issues between 1900 and 1930, but I can only reach 910H/s CN-V7 and 1000H/s CN-Heavy/Haven (at 1150/1920). Isn't a powerful result, right?

Wich timings I have to reduce/increase to improve performance in CN variants (maybe Ethash, but isn't the focus), considering the clock is a hard limitation? I have a little list, but I think is far from a complete list:
ACTRD/ACTWR, RASMACTRD/WR, TRCRD/A

But I'm not getting conclusive results. Is a painful pleasure to optimise it.

Is there another timing that I'm forgotting to change?


It would be nice to know exactly which micron is that, I have 1750MHz variant on my RX560s, and
no trouble to go over 2100, and even 2300 with loose timings

Yes, my RX460 4GB has Micron and go around 2100 (but has BGA issues). I will disassemble the RX470 to see the memory ICs to confirm (or not) my suspicions and take pictures to post here.

Hi JCE Miner,

first your miner is very nice and now supported by awesomeminer.

1 thing is not so nice, the masari hashrate is to low. Masari speed must be like cryptonight light v7.

Can anybody confirm this?
Nope

Masari is twice the V7 hashrate

Nope you are wrong. I have around 800 hashes with my RX550 and SRB 1.6.2 not tuned out on masari and cryptonight fast
Oh, we are both right.

I'm speaking aboud Ryzen's performance, you about the RX550 ;p
