Title: How to undervolt RX480 8GB using Wattman Post by: frukissa on March 23, 2017, 03:29:09 AM the title says it all guys, how do i undervolt my rx480s. i am currently running 4 rx480s in one rig with an EVGA 1200P2 SuperNova.
in the coming days ill be getting 2 more RX480 gpus ive been reading in the forum that it is safer to undervolt the cards for it to work well with the PSU im using. does undervolting decrease the performance of the mining power of the card? any help is much appreciated. im looking forward to build more mining rigs, would you rather recommend using 2 psus for one rig of 6 rx480s. If thats the case which psu would you advise me to get.

Don't use two psus for your rig Look at my Mining thread here . I have three threads started last April 2017 If you Will take time to read the three threads you will learn a lot Title: Re: How to undervolt RX480 8GB using Wattman Post by: Marvell1 on March 23, 2017, 05:19:29 AM the title says it all guys, how do i undervolt my rx480s. i am currently running 4 rx480s in one rig with an EVGA 1200P2 SuperNova. in the coming days ill be getting 2 more RX480 gpus ive been reading in the forum that it is safer to undervolt the cards for it to work well with the PSU im using. does undervolting decrease the performance of the mining power of the card? any help is much appreciated. im looking forward to build more mining rigs, would you rather recommend using 2 psus for one rig of 6 rx480s.

Also wattman can be run after the miner has started , for afterburner since it usually autostarts it can mess with the miner stsrtup process if the undervolt is too high. Also wattman can set offsets lower that afterburner Title: Re: How to undervolt RX480 8GB using Wattman Post by: pikachuy on March 23, 2017, 06:39:08 AM I say watttool wins hands down.

I assume you are using it in a batch file? Got an example of a multi-gpu command line or set?

I tried this Quote cd\ cd watttool start WattTool-0.7.exe voffset(0)=-16 ping 8.8.8.8 start WattTool-0.7.exe voffset(6)=-16 ping 8.8.8.8 start WattTool-0.7.exe voffset(12)=-16 ping 8.8.8.8 start WattTool-0.7.exe voffset(18)=-16 ping 8.8.8.8 start WattTool-0.7.exe voffset(24)=-16 ping 8.8.8.8 start WattTool-0.7.exe voffset(30)=-16 pause Doesn't work. Just loads the program Title: Re: How to undervolt RX480 8GB using Wattman Post by: Truthchanter on March 23, 2017, 03:47:40 PM I prefer Win10 over Simple Mining OS. However if your gpu is already bios modded, especially a bios mod with undervolt, then simpleminingos may be prefered as it seems easier to set up and maintain (although may have slightly lower hashrates than windows).
I prefer WattTool over all the other overclocking/undervolting tools for windows. With wattTool you can directly set the voltages or use and offset (or both). I prefer directly setting the voltages.

Is bad for the cards? I am working on a rig that will use 2, 750W PSU's The reason being that I am also running storage on the rig. so need to power 5 HDD's, 5 GPUs + fans Just curious why you say no 2 PSU, Title: Re: How to undervolt RX480 8GB using Wattman Post by: philipma1957 on March 23, 2017, 09:08:41 PM What makes you say don't use 2 PSU's?

I am working on a rig that will use 2, 750W PSU's The reason being that I am also running storage on the rig. so need to power 5 HDD's, 5 GPUs + fans Just curious why you say no 2 PSU, more complex and prone to bad wiring causing a short. I am looking at it from the viewpoint of running many rigs not one. https://bitcointalk.org/index.php?topic=1799555.msg18301758#msg18301758 Title: Re: How to undervolt RX480 8GB using Wattman Post by: Marvell1 on March 23, 2017, 11:12:09 PM I could never get the command line to work properly.

you have to use the latest version of afterburner , really anoying i wish the dev would fix Title: Re: How to undervolt RX480 8GB using Wattman Post by: frukissa on March 24, 2017, 12:33:05 AM I could never get the command line to work properly.

I dont have those cards |
