Custom RAM Timings for GPU's with GDDR5 - DOWNLOAD LINKS - UPDATED

[bardacuda]

You only need to edit the one corresponding to the type of memory ICs that are on your card. That said, if you're not sure, it doesn't hurt anything to do both unless you plan on desoldering your mem chips and putting on different ones

Hi!

Can u help me with optimized timings for the XFX RX470 4GB GDDR5 with ELPIDA memory ?

Code:

1500        777000000000000022AA1C00315A6B3CA0550F15B68C1506006AE4007C041420CA8980A9020004C01712262B612B3715
1625        777000000000000022AA1C0073627C41B0551016BA0D9606006C060104061420EA8940AA030004C01914292E692E3B16
1750        777000000000000022AA1C00B56A7D46C0551017BE8E1607006C07010C081420FA8900AB030004C01B162C3171313F17
2000        999000000000000022AA1C0018F77E4FD055121946501708006C07011D0C1420FA8980AC030004C01E19323781364718

My card default mem clock is 1750 (2000 freezes pc)

What i've tried so far is to copy 1500 values to 1625, 1750 and 2000 and managed to increase XMR hashrate from ~560 to ~614.
But i cannot get the ~860 hashrate from the first post.

Thanks !

Strange, thats not much better than my RX560

I dont know if this offtopic but i got a weird bios flashing experience. I accidentally flashed a bios intended for sapphire rx 480 4gb nitro plus (my card is non plus version). Now i can oc the mem to 2070mhz (on my default bios, artifact appearing and pc crashes when ocing beyond 1850mhz). Whats the reason for this 

[yoonline]

700$ for a bios mod? LOL

The worst part is that I want to buy it for a while but it does not answer me how can I buy

is your tool fully automated, like is it recognizing the controller and using the correct registers, or you still have to do this by hand editing ?

The wolfamdvolt/ohgodavolt? Full automation - it dynamically opens up the I2C interface of each GPU and runs a detect function for every supported VRM, which will find it if it's there. Once found, that VRM's functions are used to get/set shit as requested.

that is awesome

I2C seems simple enough, maybe I could dedicate one GPU for experimenting...but learning low level programming
on x86 could pose problem, didn't do that since Z80/6502 days

[Branko]

After lots of playing with various RX560 cards, I must say that GDDR5 cooling is one
of main factors deciding how high you can go

My Gigabyte RX560 with micron memory on average reach 100-150MHz more than other
cards just because metal plate extends over memory too, not just GPU.

And got another 50MHz applying Arctic Cooling MX2 paste instead some strange
goo that Gigabyte put there


Anyone else noticed the same on higher end cards?

Can anyone help?

I have 5 sapphire nitro rx470 4gb elpida, model 11256-21-21g with dvi-d conector (the new model, supposedly for mining)

I am using Simplemining and claymore 9.8.

I used ATIFlash and GPUz, copied straps from 1500 to above and kept TDP(W) in 85.

On simplemining, I m using core MHz 1100, memory MHz 1850, power stage 3 but cannot get more than 24MH/S per card

My power consumption for 5 cards is 780W.

Can you help me to increase haste and decrease power consumption?

1850 sounds like extremely low frequency for memory

best thing i ever read in my life that amd alwys screwing things up not only and the codify for what that other ppl can fix there crapy work.thx to the real PEEPS who sped so much time to bring this up...
im gona follow and see how things gona goo whit Custom Ram timings one gddr5 that very very very good i wana burn them muwhaha

[jeanvin]

@Branko I've got a new modded bios and now I`m getting the following results with 5x Sapphire Rx470 4gb elpida (11256-21-21g):

27,1MH/s per card
power consumption (on the wall) 850w (5cards)

core: 1200MHz
Mem: 2080

It`s very stable, but I thin i could improve hash rates and reduce power consumption, however, i have no idea how to do it...

Can anyone help?

tks a lot!

[keksik]

hello guys,
i have this version of gpu
http://xfxforce.com/en-us/products/amd-radeon-rx-500-series/rx-570-rs-4gb-dd-blackedition-rx-570p4dbd6

it use 4gb memory EDW4032BAB and H5GC4H24AJ. In my case it uses elpida and not hynix. i used custom timings from this threat and pasted it into 1750/2000:
 
777000000000000022AA1C00315A5436A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715

this is my custom bios settings:


this is my gpu Z


and hwinfo


my results in dual mining eth+lbs is 28,5 + 82 and my questions are:

- how much further i can go? using 2050 or 2025 mem is getting me mem errors in hw info...so is this maximum fort this memory?
- i can see in gpouz that VDDC power draw+VDDCI power draw is giving together  gpu power draw  value. how can this be changed? did i well to use stages in bios as above? does it have impact on these two values?
- what about only VDDC number? is 0.9313V good for 1200/2000? is possible to have less? my ASIC quality is 77%
- VRM Efficiency 99% is ok? or too high or almost perfect? im trying to udnerstand what i should achieve as best result as my gigabyte rx 580 XTR aourus 8GB is having 79% efficiency but ASIC quality is 83%

thank you

How is that different to solution presented by ethos? I mean does your tool give more control?

ethOS bought the tool FROM wolf to implement in their OS ...

So it is actually same tool in ethos?

edit. It is certainly not the same thing... New driver just work with simple voltage table edits. You can do it with polaris easly. With old driver it simply didn't work.
