I've used the AMD switcher app to do that because I don't seem to have that option in AMD settings.

I've just reinstalled drivers and it worked! I'm back at 30mh/s, very strange as I did re-install drivers previously without success, this time it worked though

Thank you all!

Thanks,

I'm using Windows 10 (64), RX580 4GB with the blockchain driver 17.30.1091 and everything was fine for many months previously. Thank you for your suggestion about switching them to compute mode, I did the switch but nothing has changed unfortunately.

Other Ethash coins still mine at 30mh/s

Hello,

I'm having a very strange issue, never came across it before, any help or suggestions will be greatly appreciated.

I'm mining Ethereum and one day I have noticed that every GPU on my rig slowed down - instead of usual 30mh/s I'm getting only 17mh/s now! I have tried different pools, servers, Claymore versions and even different miners altogether including Phoenix and Ethminer... same effect, I can only get 17mh/s. The weird thing is that other Ethash coins will mine at 30mh/s! So Pirl, Musicoin, Ellaism coin they all mine at 30mh/s, only ETH stuck at 17mh/s. Any suggestions please?

Thanks! 

Hello,

Yes, they are legit and reliable, had ordered 2 x PSU for my antminers and everything went smooth without any issues so I can fully recommend them.

Thanks

Found it on 1stminingrig, post from Otto, I'm just pasting so all credits to him:



Hi all!
After testing all day Im found one solution for undervolting with new beta driver which one works:) Maybe its a little bit primitive but working for sure for those who has rx5xx series cards. First I share my hardware. I have 7 pieces Sapphire rx580 Nitro+ 8gb limited edition in one rig. Here are what Im do:

- I have moded bios that one that Cirpian V. share with us in his blog.
- First Im remove the old one driver from the system with DDU in safe mode.
- Than I put the new one beta driver http://support.amd.com/en-u...
- Than Im install the new beta 4.4.0. 16 AB.

As many people than I have problem with undervolting. All my cards consume much more energie than before (1030-1080 mv / card with settings cc1200 mc2225) and I have also problem with heating. After all that Im do next:

- Im open WattMan in AMD's software than I click on Gaming / Global Settings / Global WattMan and chose the first card. Than Im going to change to MANUAL on voltage control and than APPLY in right top corner of the screen. Than again change it to AUTOMATIC and than apply. To do that is really Important. Than you can check in AB the voltage low down to 830-840mv. You have to do this with every single card. Also important to do this all when claymore was runing!
The only problem with this that if you shut down claymore ,or you restart your rig WattMat forget all setting and you have to repeat all theese setup. Try it, it WORK's.

If you have any questions with my setting do not hesitate to ask. If you try it and it's work than buy me a beer ))))
ETH:

Same situation for me. I've followed all the instructions very carefully and all my 3 rigs (RX570 and two RX580, all 7 GPU's) draw about 200W more per rig. Afterburner does work in a way that it reduces the power draw but still I can't come nowhere near as on the old drivers. I think the cause of it is that Afterburner Beta 16, at least in my case, doesn't undervolt all 7 cards in a rig.

I've looked int GPU-Z and yes, first card have lower mV and responds to whatever settings I use in Afterburner, but another 6 cards draw a full power from my PSU hence overall I'm 200W worse than before.

Seems like we need another way of undervolting it, Claymore doesn't do the job for me and rig is very unstable.

Hi,

Can you do review of any cards suitable for ETH users, please? 

I've just done my first deposit to uquid and I'm extrmely dissapointed. Sent a test 0.1ETH to my GBP account, various exchanges were showing this as roughly £31-£31, uquid estimate was showing as £30.10 and I thought it's acceptable and proceed. 20 minutes later my uquid account has been debited with less than £25! It's a daylight robbery in my opinion and I'm glad it was only a 0.1ETH.

I'm waiting to see what Monaco will look like, also have tried Wirex card, it's highly reccomended by you but it came out even worse as they do ETH->BTC->GBP and from my 0.1ETH I've received even less. 0.1 ETH was on exchanges worth about 0.0135 BTC, after wirex exchange I got only 0.0105. Suddenly my £30 worth of Ether became £23 and then Wirex obviously still wants to charge me to transfer that into GBP, so finally it would be £22.

Maybe there is no good card on the market yet and best way to spend crypto is to use Kraken and withdraw in EUR to UK bank?

Thanks for all the help!

Can you reccomend any other GBP cards to spend my Ethereum please? I'm waiting to see what Monaco will look like, also have tried Wirex card but that's even worse as they do ETH->BTC->GBP and from my 0.1ETH got even less.

Creepas is a great guy, extrmely helpfull and knows his stuff. Met him personally a few weeks ago so I know he is a real deal, keep it up!
