Thanks dude, it works good yet my hashrate are still low. I guess i will have to reinstall properly my driver in order to have my hrate back to their level before Spectre update.


Best,

Bob

^^^ The Ethereum DAG is too big with those old cards. They have enough RAM but it's another issue that causes the hashing speed to slow almost in half. ETC has the same issue.

Mine a newer coin with a smaller DAG like MUSIC, UBQ, EXP, PIRL, ELLA, etc. and you'll get 25 MH/s. 30 MH/s with those mining straps.

Anyone experience with R9 380 ? I have 6 cards ( Sapphire Nitro and MSI ) and I dont know what`s wrong with bioses. I see on forum, people who get 25 mh/s on ETH with this cards.

I use hex editor and I copy string from 1500 MHz and put on 1625 MHz and 1750 MHz ... no success !
After that, I found some strings on "google" and I test few ... I found only one who works fine with Elpida and Hynix memory ( about +2 mh/s )

Stock 1500 Mhz string : 77 71 33 20 00 00 00 00 CE 51 6A 3D 90 55 11 12 30 96 49 09 00 4A E6 00 22 33 9D 08 74 01 14 20 6A 89 00 A0 02 00 31 20 15 0F 29 2F 94 27 31 16
New string : 77 71 33 20 00 00 00 00 CE CD 59 39 80 55 11 11 2E 15 89 08 00 48 C6 00 22 33 9D 08 6C 00 14 20 6A 89 00 A0 02 00 31 20 14 0F 26 2B 88 25 2F 15


OS : ethOS
Miner : sgminer
Stock bios : 18 mh/s ( ETH only )
Moded bios : 21-22 mh/s ( ETH only )
OC Settings : Sapphire card ( core 1140 and mem 1715 ) - 22.37 mh/s ; and MSI card ( core 1120 and mem 1630 ) - 21.27 mh/s  ; and other more OC settings Smiley

i could email it to you if you want it, i dont know how i can upload it to here,i will look into it and will post the bios here today maybe, need to know how
You can use http://www.zippyshare.com/ Just upload it there and post the link.
Thanks  Smiley

Hi, sorry it took a while, but here it is, Sapphire rx550 4GB Micron with 10 CU's; stock bios:
http://www79.zippyshare.com/v/lGcaFMLG/file.html

stock bios it does 280 hash, i put 1250 strap at 1750 strap and put memory at 1850 mhz, and got arround 380 hash.
You can probally do better then this, i tried one strap lower and the card would lockup, but ya, i only tried copy paste lower straps into higher ones.

Zippyshare tried to mine xmr, get me to date hot asain woman and call a tech support hotline in Nigeria just before locking then crashing my browser.

hi bro notbatman,

kindly need your assist on modify the bios mod, im trying to use polaris editor to change the strip from 1500-2000, but still not working.

GV-aorus RX580 8GB micron memory
http://s000.tinyupload.com/download.php?file_id=96432612022382752441&t=9643261202238275244160937


another tricky part is im using msi afterburner to set the memory clock to 1150, but it still run over the afterburner momory clock limit up to 1300mhz, and cause gpu hang. any solution to solve this? =)
pls help. thanks bro.

Did you try to unlock rx550 8 CU'S into rx550 10 CU'S yet?

Notbatman, Coinbasedgod,

I have searched all over the places for MSI RX570 8GB OC ARMOR with Hynix memory modded bios that will get a rate of 28-30 Mh/s.  Do you happened to have this modded bios?  I tried several mod files but not of them increased from the 24Mh/s I get from the original bios.  I see a bunch of modded bios for the 4GB GPU and other RX570 but nothing on the MSI RX570 8GB OC ARMOR.  Any help will be much appreciated.  Thank you.
Have you switched cards to compute workload? http://support.amd.com/en-us/kb-articles/Pages/DH-024.aspx

I do not see that option to switch to compute workload on AMD.  I am using the Blockchain driver from Aug 23.   Am I suppose to see the option to select compute?

also, one of my rx550's has 8 compute units, and  the other one has 10 compute units, i didnt modify anything to them.
gigabyte rx550 2gb has 8 compute units, sapphire pulse 4gb has 10 compute units.
Please upload the BIOS with 10 compute units. I have never seen before.

Yeah that's interesting, I'm guessing it's actually a 560.
Now, I read about the new RX550.
Saphire Model 11268-15-20G .... 10 CU !
https://forum.level1techs.com/t/sapphire-made-a-new-gpu-again-rx550-pulse-10cu/124326

Update:
The new RX550 (Lexa Pro) has 10 CU, but I only can find cards with 1500MHz VRAM. Not good for mining.

But maybe we can unlock the old RX550 with the fast VRAM  Grin .
Please upload the VBIOS !

If your card has memory heat sinks and a good fan then I can do a 550 mod, I'm doubtful it will work with the windows drivers though. The Linux beta mining drivers do support modded 550's.

Post your stock bios if you want.

i can put a custom heatsink on it and  memory heatsinks, i did it on another rx550 it doesnt gets over 45C while mining.

This Sapphire pulse 4GB  of mine has  10 CU, i have the memory running at 1850 mhz, i can get 385 hash out of it, more then the 300 hash i get from gigabyte rx550 2gb with 8 CU.
Could it be a rx560 with 4 CU'S disabled?

Anyone experience with rx550 elpida memory?
I put the 1625 strap at 2000 and got a LITTLE improvement, but still only have 280 h/s.
Trying more straps now but i dont think this elpida is the best memory.
Try this:
777000000000000022AA1C00315A5436A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715

Good luck  Wink

No succes, i tried the strap, but i cant even boot into windows with it, black screen.
