is there any topic for beginners?
is there any topic that collect best timing for each card
i have sapphire rx470 4GB Elpida and on ETH have 29.5Mh/s
is it the best result i can have?

I recently decided to take another look at RAM timings now that many people have been playing with custom timings for several months.
Instead of zeroing FAW/32AW as I do in my strapmod utility, I think it is better to set them low. 7/10 seems to be standard for Hynix straps, while 6/8 is typical for Samsung. My testing so far using 6/8 on Hynix gives the same performance for eth mining as 0/0, while potentially being more stable at higher memory clocks.
I also suspect the field labels may be reversed, so FAW is really 32AW, and vice-verse. In my testing, when I set "FAW" to 8 or 10 while leaving "32AW" to zero, I see no slowdown in ethash speed.
I may update my strapmod when I'm done, but my goal is to finally finish a Linux tool I started working on last year that tweaks timings at runtime. This allows for tuning the memory timing for ethash, equihash, or cryptonight without reflashing the BIOS and rebooting. It has already greatly improved strap testing, as I have been able to modify timings on the fly while mining; I don't even have to restart the miner. I still crash the GPU a lot, as dynamically switching between two sets of good timing will still cause a hang depending on which timings you switch in what order.

It's a complex topic, so it takes a lot of reading and research to understand. At 29.5Mh/s for eth, you're not going to get much better than that anyway. |

So you've been playing with umr  Are you going to release your tool for the public or keep it private? I myself have similar tool that does that but only for private use. |

I started playing with umr last year shortly after it was publicly released, but only tried a few of the many dozen gmc81 registers. I had shutdown my mining gear for the summer, and had some hardware issues when I fired the rigs up in the fall. Right now the tool is just a script that uses umr, rocm-smi, and ohgodatool. I'll likely keep it semi-private, as I don't want to support it. When it's integrated into miNR (that's what I'm going to call the miner I'm writing), I'll probably release it open source. Most of the configuration will be automatic, so users won't be able to mess with global/local work sizes, and so it should be mostly idiot proof (at least for those with enough clue to run Linux). |

is there a topic or help file that explain each value of the strap? i use SRBpolaris and its strap editor and can see binary value but i have no idea what are they and what is the result of changing them |

Hi
Currently I have HIS RX570 4GB with Elpida EDW4032BABG. Default straps is below:
1500: 777000000000000022AA1C00315A6B3CA0550F15B68C1506006AE4007C041420CA8980A90200000 01712262B612B3715
1625: 777000000000000022AA1C0073627C41B0551016BA0D9606006C060104061420EA8940AA0300000 01914292E692E3B16
1750: 777000000000000022AA1C00B56A7D46C0551017BE8E1607006C07010C081420FA8900AB0300000 01B162C3171313F17
2000: 999000000000000022AA1C0018F77E4FD055121946501708006C07011D0C1420FA8980AC0300000 01E19323781364718
I am copying 1500 to 1625, 1750 and 2000. By setting memory clock to 1950Mhz (1040mhz core), I am able to get 750hash/sec cryptonight or 28 Mh/sec Ethash. Any idea if this can be improved further?
Thanks

What mining software do you use ? Try this strap : 777000000000000022AA1C00315A6B3CA0550F15B68C1506006AE4007C041420CA8980A90200000 01914292E692E3B16 or : 777000000000000022AA1C0073627C41B0551016BA0D9606006C060104061420EA8940AA0300000 01B162C3171313F17 maybe : 777000000000000022AA1C00315A5436A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715 ( 990h/s on my card @1250,2075 ) Please report the results. Good luck |

Hi, I am using latest claymore cryptonight. Between the three, I am guessing that the bottom one is the most aggressive timing with best results? So I tried that @1208,2000, 963mv vddc (higher than 2000 makes it got too much memory error count in HWInfo64, and I now got 910 H/sec cryptonight each card. Thanks for helping  |

Do you mind to also help me with tweaking these card? Anyone? Currently only getting 800 hash/sec cryptonight with just copy paste 1750 to higher.

Any old timers here get any good results with legacy GPUs.
7970/280x I get about 620 H/s
290 I get about 700 H/s
R9 270 with Hynix I get about 530 H/s
Anyone play around with their memory straps to get faster speeds?

You get The Stilt's straps for those, hes the original bios memory strap modded. Check out the overclock.net forums. |

For R9 290, its seems more limited by core. Increasing core from 945 to 1050mhz gave me 850h/s with stock memory straps at 1500mhz mem. Also, this was way back, when the compute drivers still werent released.

What equihash coin are you mining? I've been mainly mining EXP with my old Pitcairn cards (mostly R7 370s). I get about 18.5-19Mh with minimal timing tweaks, 1150/1550 core/mem. On equihash I get about 190sols/s, which usually makes less than EXP. |
