Title: Low hash rate with 2 RX580's Post by: Reptar0nIce on June 11, 2017, 03:59:49 AM Hi all. I just set up a couple GPU's in my PC (figured I'd start small before jump into a 6 GPU mining rig, and you can't find cards anywhere). Right now I'm pulling 45ish Mh/s, but after researching I feel like I should be able to get 55-60. I've already done the bios mod (changing the memory timin I believe). I followed a couple guides, yet when I down clock my core clock, and increase my memory clock I only get 11 Mh/s per card. I'm not sure what steps I'm doing wrong. Any help would be greatly appreciated!
ETA: sorry, forgot to add some info. I'm trying to dual mine using Claymore (latest version) ethereum and siacoin (my siacoin hashrate is 1400 Mh/s, don't know if this is good or not). I'm on 17.4.4 AMD drivers. I'm pool mining on Nanopool. And the cards are both PowerColor RX 580's. One is a Red Devil and the other is a Red Dragon.

That seemed to help a little, but I'm not able to really get over 48=50 mh/s. I've tried upping the memory clock, but I seem to get a BSOD when I push it up to 2200. Anyone have other suggestions? I'm currently mining just ETH, and still seeing the same hash rate.
Title: Re: Low hash rate with 2 RX580's Post by: Jackblow33 on June 13, 2017, 10:18:15 PM Maybe, starting up from scratch could be an option.
-Try with just one card first. -Uninstall driver with: [Guru3D.com]-DDU -Install latest drivers, Im using 17.5.2 -Reboot -atikmdag-patcher-1.4.5 If it still the same after that steps, questioned yourself about your modded bios? Wich brand of ddr your gpu have? GPU-Z.2.1.0 to identify your ddr. Mining Eth +SC now with pretty conservative settings (Ulta-stable) and got on my test pc Eth=57-58 mh\s, SC= 865 mh\s with just rx570 4g, could go up to almost 60 but lose some stability. Guess you should have 60-62 easy with your rx 580. Im using -dcri 15 with Claymore 9.4 and it doesn`t affect my Eth hashrate. Just take a look at my settings and see how my cards are not pushed that hard and still produce result with 100w. http://imgur.com/a/ituG3 (http://imgur.com/a/ituG3) Here is a batch file that is working: setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100 EthDcrMiner64.exe -epool us1.ethermine.org:14444 -ewal Your_ETH_wallett_address.Name_of_your rig -epsw x -dpool stratum+tcp://us-west.siamining.com:7777 -dwal Your_SC_Wallet_address.Name_of_your_rig -dcoin sia -dcri 15 Just choose the pools you want and edit the batch file. Good luck! Title: Re: Low hash rate with 2 RX580's Post by: va23boam on June 13, 2017, 10:36:12 PM I tried your suggestion and lowered the intensity for sia.

I'm currently mining just ETH, and still seeing the same hash rate. 1. load gpuz see what memory the cards have 2. Make sure u have edited the correct timings some have 1: some 1: & 2: 3. Load amd go to wattman global reset all settings. 4. Run msi afterburner and overclock/underclock select run windows startup 5. Possibly reboot and test with claymore 9.4 6. try connect monitor to gpu then close restart claymore 7. Use -dri 10 for dual siacoin dual mining so eth isnt effected Title: Re: Low hash rate with 2 RX580's Post by: Reptar0nIce on June 13, 2017, 10:50:59 PM Thanks for the suggestions. I'll give them a try when I get home. The RAM on the cards I have is Samsung.
Title: Re: Low hash rate with 2 RX580's Post by: Reptar0nIce on June 14, 2017, 03:19:42 AM Got home and played around with things a little. I started with the Red Devil card. I verified that the straps were set correctly. I was able to get 29 mh/s with this card by itself! Core was at 1100, and memory at 2100. Upping the memory to 2200 seemed to drop hashing down to 11?
Then I moved onto the Red Dragon. It looked like I missed changing the memory straps on this one. After making the changes I tried mining with it alone and am only getting like 18 mh/s :(. Looks like the memory is Hynix? Is that the reason it hashed so low? I might have to just sell the Red Dragon I guess and try to find another Red Devil. ETA: The Red Dragon seems to be all over the place with the hashing power. It varies from 5 to 18.

ETA: The Red Dragon seems to be all over the place with the hashing power. It varies from 5 to 18. Nope dont sell it its definitely a setting somewhere. All 570 and 580 hash around the same With 2 diff cards maybe try use the amd tool to over clock. Or turn the sia intensity down with the +/- buttons on num pad (claymore 9.4) After you do an overclock with msi afterburner/amd wattman always close/restart claymore. Out of interest whats the siacoin hash? Is it the same as the red devil or more as this would indicate an intensity problem. Otherwise id suggest the over clock has only been appied to the 1 card. U can select the red dragon in the gpu option in msi after burner and confirm the over click is applided to it? Title: Re: Low hash rate with 2 RX580's Post by: stna1981 on June 14, 2017, 11:20:44 AM I have a similar issue. With a Sapphire ITX RX470, I only get around 22 MH/s at stock speed and maybe 23 Mh/s with memory up to 2000. How much would other memory timings / BIOS mod affect the result? I've read about people getting up tp 30 Mh/s out of a RX470, is this also possible for RX570, and is this only becuase of the changed memory timings?!?
Title: Re: Low hash rate with 2 RX580's Post by: Ahead on June 14, 2017, 12:16:19 PM Hi,
First of all, start with ETH only mode. Not dual mining. Once you are happy with the results in single mining mode (ETH hashrate), then start to experiment with dual mining and whatever coin (DCR/SIA/etc...) Trying to fine-tune both coins (dual mining) from scratch is a pain... since you don't have a reference of what is the maximum hashing power of each card on ETH. Title: Re: Low hash rate with 2 RX580's Post by: stna1981 on June 14, 2017, 12:21:47 PM I did not use dual mining to get my first results, so all figures are ETH only... :(
Title: Re: Low hash rate with 2 RX580's Post by: Ahead on June 14, 2017, 12:29:43 PM I did not use dual mining to get my first results, so all figures are ETH only... :( My reply was for the person that started the thread, but it may help others too. Since I have a 7x rx470 rig (asus strix OC 4G), I can share some settings with you. Did you made bios mod on the cards? (copy 1500 timings to all the boxes under 1500 in polaris bios?) If yes, then the setting's I'm using on MSI afterburner are as follows: Core Voltage: -96 (can't go -100) Power Limit: -50 (ETH only mining) and +0 (for dual mining) Temp Limit: 90 Core Clock: 1110 Memory Clock: 1950 Fan speed: Auto I'm getting 27,8 Mhs for ETH only, and 20,1 Mhs ETH + 605 Mhs SIA (dual mining) Hope you can replicate the setup and get your hashrate up Title: Re: Low hash rate with 2 RX580's Post by: stna1981 on June 14, 2017, 12:52:40 PM Is it really the lower timings that is responsible for the almost 20% higher hashrate or also other factors?
Title: Re: Low hash rate with 2 RX580's Post by: Ahead on June 14, 2017, 01:14:23 PM Is it really the lower timings that is responsible for the almost 20% higher hashrate or also other factors? My cards with stock bios and settings are hashing at 21,5 Mhs Modded bios let's you push the cards and lower the power consumption It is up to you if you want to do it or not. (since it voids warranty on the cards in many cases) Also the memory manufacturer of the cards is crucial. My Elpida memory cards are hashing a little higher than the Hynix memory cards (1-2 Mhs) One other thing you can check to see if your overclock settings are working OK is to check for memory errors (card memory errors) To do so, I use HWinfo (google it and install it, it's free). Start the program in "sensors only mode", scroll to the bottom (or almost the bottom) and search for the "memory errors" field for each card. (each card is listed in it's own set of info) Check if you get too many errors there. If so, try lowering the GPU memory clock until you get 0 errors. Also keep in mind that when you change setting in MSI afterburner (or whatever program you use to change overclock your card) the mining software should be stopped (closed) And between tests, restart the rig (just to be safe that everything is starting from 0 on your tests) Title: Re: Low hash rate with 2 RX580's Post by: va23boam on June 14, 2017, 03:53:48 PM I did not use dual mining to get my first results, so all figures are ETH only... :( My reply was for the person that started the thread, but it may help others too.

I copied the timings from 1500 to everything under it, yet it's still hashing at the same rate. I even copied the 1750 to 2000 as well. When I try to raise the memory clock up to 2100 it goes DOWN. This is one ETH mining only. Maybe I got a bum card?

On 8GB cards you only copy the 1750 timing value to the 2000 timing value. Watch this video for more info.. --> https://www.youtube.com/watch?v=JKM60VVIfRg (https://www.youtube.com/watch?v=JKM60VVIfRg) Remember to make changes to the factory default bios, not to the one you have already modded!

Use performance timings like Uber-Mix. In my signature there is link to the guide how to easy mod the bios with Uber-Mix timing for Samsung memory.Title: Re: Low hash rate with 2 RX580's Post by: machinegunate on June 17, 2017, 07:48:51 AM I'm having the same issue with all my cards.

I think this is the best you can get with stock bios. Also Hynix memory is not the best. I have rx470 with Elpida memory and with Hinyx memory. Elpida is doing 1 Mh more than Hinyx cards, and it can run memory at higher clock speeds (50-100Mhz more) Title: Re: Low hash rate with 2 RX580's Post by: va23boam on June 18, 2017, 10:09:51 PM I really for the life of me can't figure out what the issue is.

I have 1 Sapphire RX 580 8GB NItro+ HiNyX card that won't get past 22mhz dual mining - ETC & LBC - no matter which bios I try, and any OC settings just make the hash worse. I have tried 4 or 5 different ones. I have tried and double checked everything...My RX480 8GB Nitro+ Sapphire runs at same speed. All threads to this problem seem to dead end, so I'm replying to this dead one in hopes someone found a solution? Or were we lucky to get a bad batch of the last of rx 580 hinyx boards? UPDATE: I have discovered some of these cards have *2* different mem manuf. - mine has BOTH Samsung & Hinyx - also had to use another version of Polaris Editor - SRBPolarisV3 allowed me too see the correct memory straps for each Samsung and Hinyx. Since none of the bios I downloaded made no improvements, I would try manually adjusting. I could not do this before, so I tried editing/copying the straps ... a few different combos tried on each pair. No improvement. Stuck again at same 22mhz hash rate ... no matter the strap copy combo... hash is even lower on the stock bios setting btw. 19mhz. Title: Re: Low hash rate with 2 RX580's Post by: TotalChomper on December 02, 2017, 05:30:52 PM I'm having the same issue - can't get past 16 MH/s with a Red Dragon RX580 8Gb Hynix!
Interestingly enough, I can only get 33 Mh/s with a Vega 56 which seems like 50% less than anyone else. Are there any other settings which may be bottle necking this ? This applies to ETC / ETH single and Dual Mining in Claymore, standard drivers, no BIOS mods.

I just tried backing up to the suggested drivers (17.11.4), but the hashrate did not improve, and Afterburner wasn't able to measure GPU temp on either card or voltage on one. Possibly an incompatibility between latest Afterburner and the Nov 27 drivers. I keep reading that stock, out of the box, I should be getting >22 MH/s with these cards. Using Afterburner prior to this, I was able to tweak it from 17 MH/s to 20 MH/s on the RX580 card. No BIOS update or anything more. I'm running on Win 7 64-bit. Noted that Dev Mgr reports a completely different driver series number, but the installer reported the expected number when it completed. Now back to the latest driver (17.12.2, I think).
The RX480 has Samsung memory. The RX570 has Elpida memory. When I only had one card (RX580) I wondered if running the display on one of the cards was taking up some of the processing power, but I've got both cards now, and the display is only running from one of them, so that can't be it. (And nobody has said that this affects the hashrate.) I'm stumped. I should be able to get to at least >22 MH/s without doing any BIOS updates, right? I'd like to just solve the base issue for now.

Thanks Gotta run Windows 10 - 64bit ...Windows 7 will not allow the speed&x lanes needed Title: Re: Low hash rate with 2 RX580's Post by: Kofik7 on January 12, 2018, 10:49:16 PM That's my recent setup

I have installed fall creators update, lates amd mining drivers, copied the straps 1500 to 2000, it did bump speed a bit but currently 22 MH, no where near what everyone claiming to be 28-30 Mhs. Using power color 580 red dragon 4gb with hynix memory. Did overclocking with msi after burner as well but not much help. Title: Re: Low hash rate with 2 RX580's Post by: surferdudemi on January 23, 2018, 06:45:55 AM Switching to Win 10 partly fixed the issue. Switching to Compute instead of Graphics in the utility boosted the rate quite a bit. What helped even more after that was turning off Crossfire! The first time I tried it, the system crashed. Perhaps that was with Win 7 - don't recall. But this time it worked fine and I was able to control the cards separately and get to about 23 - 24 on each card.
Thanks for the advice. Title: Re: Low hash rate with 2 RX580's Post by: alforro on May 07, 2018, 11:20:39 PM anyone with this issue on simplemining? I have 4 rx 580 asus strix 8gb, two of them are mining eth at 27mhs but the other two are only at 22mhs, non of the cards have OC nor bios mod.
Title: Re: Low hash rate with 2 RX580's Post by: miningchamp93 on June 28, 2018, 12:05:24 PM Hi all. I just set up a couple GPU's in my PC (figured I'd start small before jump into a 6 GPU mining rig, and you can't find cards anywhere). Right now I'm pulling 45ish Mh/s, but after researching I feel like I should be able to get 55-60. I've already done the bios mod (changing the memory timin I believe). I followed a couple guides, yet when I down clock my core clock, and increase my memory clock I only get 11 Mh/s per card. I'm not sure what steps I'm doing wrong. Any help would be greatly appreciated! ETA: sorry, forgot to add some info. I'm trying to dual mine using Claymore (latest version) ethereum and siacoin (my siacoin hashrate is 1400 Mh/s, don't know if this is good or not). I'm on 17.4.4 AMD drivers. I'm pool mining on Nanopool. And the cards are both PowerColor RX 580's. One is a Red Devil and the other is a Red Dragon. https://miningchamp.com/gpus/91/Sapphire-RX-580-Nitro+-8GB-hashrate Title: Re: Low hash rate with 2 RX580's Post by: RudysoRudy on July 17, 2018, 06:27:43 PM looks like i am having a the same issue. I have 3 rx 580 8GB cards one hashing at 27.5 and the other two at 22.5. when i try and overclock them i get no result but if i raise the memory clock high enough my mining rig crashes. i also have gtx 1060s 6GB and i can get up to 23.5 just fine. i can use the MSI after burner to raise the hash rate but i can not do that for my AMD cards.
if anyone has a solution please advise thank you Title: Re: Low hash rate with 2 RX580's Post by: swogerino on July 17, 2018, 06:57:04 PM looks like i am having a the same issue.

For example the latest version 4.5.0 of MSI can recognise the latest Adrenaline driver and also the Blockchain driver differently from previous versions which cannot recognise both. Check which driver are you using and if you see Adrenaline and not Crimson Beta make sure to 1. Right click on empty space on desktop 2. Choose AMD settings 3. Global Game settings 4. Make sure you change from Gpu workload graphics to Gpu workload compute. Also remodify the bios if you haven't already done so.
