this is my rom if i messed up somehow above copying them manually https://drive.google.com/file/d/1BfGFmzANLC630SgTCw5UY2sCHl4SsctE/view?ths=true

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.

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.

Aah well, cryptonite benefits more from looser timings and higher clocks, than dem tight ass timings.

Yeah already running the Stilt bios for the 290. Doesn't seem to make much difference from stock with XMR.

It helped during Litecoin days.

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

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?

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.

What tool are you talking about?

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

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  

Told you it was available. And yes, they will tell you EXACTLY what you wish to know, though - this translates to the register more or less directly, which is why I gave you the hint.

Hi

Currently I have HIS RX570 4GB with Elpida EDW4032BABG. Default straps is below:
1500: 777000000000000022AA1C00315A6B3CA0550F15B68C1506006AE4007C041420CA8980A90200000 01712262B612B3715

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

You can download JEDEC GDDR5 datasheet from their web

Stop looking for the info on a silver platter, and start getting creative. In this case - you don't even have to get creative, such as looking in the AMDGPU driver code, because it's in the GDDR5 specifications from JEDEC.

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

SEQ_MISC8 can be useful - but you need to be careful, because not all GDDR5 ICs support the optional features which is can enable/disable.

What is umr ?  

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).
