How are those aliexpress thermal pads comparable with real stuff?

Are nothing. Big diference from a generic shit to a good product.

About the tests:
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

Elpida

[QuirkSilver]

Its not a generic shit, the Fujipoly, Laird and Arctic etc. have higher heat dissipation, although i also thought each chip barley consumes 2 watts, but for lower end GPUs anything is better than nothing at all, the ram die is non heat conductive, imo , roughly, anything of 6 w/k-m +++ is useful if its attached to the heatsink directly, thats why i really like those gigabyte Aorus, not expensive but memory have an engraved spot in the heatsink and a thin thermal pad is there.
Those Hynix 4gb 580s (3 of them) with one click strap, can go 2100-2200mhz (although the strap is bad) compared to MSI gaming X 570s, same memory not cooled, they do 2020-2090 mhz.
The generic or high end is useless unless heat is dissipated somehow! also i would use thin layered (0.5-1 mm) thermal pad + a bigger shim or heatsink if you have your own idea of attaching thermal pads+shim or whatsoever to the gpu heatsink then thats perfect.
Those generic thin silicon pads are for cheaper GPUs 560, however i will get something better but with fair price/quantiity ( i have 15 GPUs in total half of which are 560s, so I'm a poor miner )

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.
Do you do BGA reballing? i have got almost everything for GPU modding (but damn, to buy 1 DIE of Samsung memory, its better just to buy a full 580 8gb Samsung going 220$ here used on ebay)
I have a gpu that BSODs at anything higher than 1865mhz.. its an Asus strix 570 its NOT memory errors, i never get any errors at whatever timings at this frequency....it also shows VDDCI amperage 208 amps in HWinfo!
another is 560 2gb hynix, that crashes and gives errors with whatever timings barely makes 1850mhz!!


Appreciate if anyone can tell me how to decipher those MC-SEQ-1 reading a post by laik from 22nd march 2017 in this thread, still struggling with the crap.

Yup, these brands are known as good. But I bought really generic shit (lol)

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).

Let's try to find the limit at lower clocks  

[QuirkSilver]

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.

Is tCKE linked with SEQ_MISC1?

Nice hash from damaged elpidas

About my lastest tests:
- No matter what I do with straps, at 1950+ I have incorrect ETH shares or compute errors in CN mining). 1930 is fine;
- Tried SEQ-MISQ1 and CAS from 1500 strap. Mining doesn't starts, bsod after closing miner.
- Tried tFAW32 bumped to 6. 12H/s loss. Sticking at 4.

regarding tcke, not exactly sure, but 90% it is indirectly dont forget there are other Misc lines not shown. What works though and confirmed by wolf (or thanks to wolf) tCL can tolerate +1 extra difference over the corresponding MISC-1 value. Also, you can change r2w and w2r freely for stability, that makes rules much different and easier, found a 1kh/s hynix (based on 1500 mhz strap though) with this way stable on hynix, non cooled at 2125 (few errors) this card used to do loads of errors @ 2025 mhz! and give 912 h/s with one click.
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)

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

This is the first time I've seen this utility. I’m already using OhGodAnETHlargementPill and I’m satisfied with results. I hope that OhGodATool also has such a quality and will help to increase mining performance. Have a success in your great job!

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.

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

[QuirkSilver]

So busy with the mass availability of 8gb Polaris in perfect conditions for less (as low as 290 Australian dollars, thats nearly below 200 usd.... for GOOD variants) also waiting for the Launches next week hesitant on buying some of those Polairs or not..Its not a gamble since prices can't go any cheaper lol.
Anyway, did decipher/experiment with MR0/8 etc. But for ,Hynix Specifically, you need more than that. Some timings are in Nanoseconds, others are based on tCK. I think RASMACTWR is tied to tRFC but funnily until now i'm not sure what rules bind tRC and tRFC in hynix (increasing tRFC and RAS2RAS substantially without adjusting other stats, adds some stability yes but not sure if thats the right thing.)

MISC1 for Hynix AJR 1625 First change the Hex to binary
0x20140475 >> 2014 and 0475 2014 is the MR1 and 0475 is MR0

MR0
*0475> 010001110101, now starting from the right hand side-you need the JEDEC Lookup table from the standard- Write Recovery values are the straight decimal values (101)= 5 so Write Recovery is 5
*The 4 bits after write recovery are CLmrs its equal to tCL-1 , lookup table here doesn't start from zero, but starts at 5, so for our strap, 1110 is 14 adding +5 its 19 but thats CLmrs so tCL is 19-1=18
That was for tCL up to 19 more than 19 is supplemented by an extra bit from MR8, the A0 bit specifically and its added to the left.
*The next bit after CLmrs is useless (TM) ignore it, then the next 4 bits are Write Latency which is also a table lookup and also has an extra fifth bit added from MR8 (because WL values are usually above 20 so the 5th bit is mostly in use) WL  0100 with the 1 bit from MR8 10100 WL look-up table starts from 4 so the decimal value of this Binary (20) is combined with (4), so WL is 24
Hynix doesnt like 20-21 tCL though (changing the binary) for some reason. The higher Hynix straps start with 23

will continue later have to finish my shift!

[Satunaimrotes]

I do have the 4gb version too which i can clock to 30mhs no problem. Just the 8gb which is being a pain.

XFX RX 470 4GB Elpida with eliovp's strap that's around the forum for long time with equal TRCDR/A fix, I make around 850h/s with claymore xmr 10.2 , and about 920h/s with gateless gate at 1170core/2000mem/875mv , at about 2-3-4 errors per hour. With claymore xmr 10.2 hashrate is stable with rare low fluctuations to 800-820 , with gateless gate 0.1.3-pre6b fluctuations are a bit more , but averages at about 920-925 , new gateless gate sharp gives me almost the same results , old gateless gate is based on sgminer , so hashrate is about the same as sgminer, for me a little bit more than sgminer-5.5.5-gm-nicehash-8.

edit: With the same strap, same 1170/2000/875 on ETH make 29.5mhs , eth and xmr are stable with these settings , memory can go up to 2050 before significant error rate , but stability goes down with it. Claymore xmr 10.2 settings -h 928 , gateless gate settings 896/8/2 , claymore eth 10.2 -dcri 8

Hello GUYS!

I have searched like idiot, really Reading every line of every page, googeling line retard and still havent found something good.
I use 'One click straps' on Polaris Bios Edition and modded my cards.
Running on 1200/2200 and can get only about 800 h/s on Crytonight Heavy when others get 1000 h/s+ with lower settings like 1150/2000 and RX 470/480 or something. ( I dont know what i do wrong )
I have tried everything, but it seems there is a diffrence between ETH and XMR mining timing straps? (Cuz i have ETH i Think)
I have tried to copy 1750 to 2000.. or 1500->2000 but still I dont manage to go over 800 what ever i do.
My ASCI percentage is around 70-75% on those GPU's and i run them at 1150-1250 and 2200-2300 without any errors but it gives like same results what ever i do, cant manage to go over 800.

I have one rig with 8x Sapphire RX 580 8 GB.
3 with ( K4G80325FB, Samsung - H5GQ8H24MJR, SK HYNIX )
5 with ( MT51J256M32, Micron )

If you can please PM me some timing straps, or I can send you BIOS file you can mod it for me that would be awsome.
I wouldn't be asking this from you if I found my self. Ty guys

Sounds like its not straps that are your problem, but your cryptonight miner settings
