Hi folks,

Anybody got some tips on how to dissipate heat from mining rigs?

the cards are reporting about 55-60C but it warms up the space quite well.

Normal room temp is about 10-20C over here.

Goes up to about 23-25C.

Thinking Im doing something wrong. Been running a fan at the rigs 24/7 but heat seems to get trapped in the room.

Saw some youtubers with air flowing thru across the room. No AC.

How do you guys deal with heat issues?

Is it necessary to run an AC when the temps go up to 20-30C ?

Thanks in advance, folks!

Hi all,

Instead of Afterburner, I tried to change voltage by adding -cvddc 900 to claymore command, but my GPU is not responding to it.... in fact the GPU remain idle while claymore is running with -cvddc and it was producint 0 MH/s.

RX580 card was bios modded with polaris one click option.

any idea whats wrong? is -cvddc not supposed to work with RX580s?

Hi guys,

Total noob here... Finally got my rig up and running with 6 rx580s... btw, thanks to all those who helped me out along the way.

I ran my rig for a few hours and am getting into an issue with temperature readings. Some of the cards run at a higher temp than others.
As far as I checked, the spacing and physical location doesnt really change the temperature read outs. I keep them all fairly separated.

Most of them average at 66C, but there is one card that runs like 72C. Is this normal in your rigs?  or should I do something about that card that runs hotter than others?

They all average about 29.5MH/s with about 15-20% undervolt thru MSI AFterburner

Hi folks,

What are your true mining return vs expected return calculated by sites like CryptoCompare?

Their return numbers are very good right now due to recent rise in ETH prices, but how much should I take off the calculated numbers? Are they calcualted based on best-case scenerios?

Thanks in advance...

Hi folks,

Putting together a 6 gpu rig that hopefully run 24/7....

I'm wondering if I need to replace the PSU's #18 AWG pcie 8pin + 8pin pigtail, to 16 AWG ones?

Would it make a big difference? I will be using the same cable with PCIE 8pin on the gpu and the pigtail with extension cable will go into the 6pin on its riser board. The pcie cables that came with the psu are 18 awg.

Guys, got a general question regarding RX580 varieties.

Is it better to cryptomine RX580 cards with 8+6pin power input ? or get the ones with only 8pin power input? I see sometimes the same brand offer both varieties.

TTheoretically 8pin would draw 150W max and 75W from 6pin cable. The riser board also need 75W to feed the graphics card thru PCIe slot. Would 8+6 ease the power load from the risers?

Can anybody explain how all this is supposed to work together?

Hi Folks, thanks for maintaining a great site with a wealth of knowledge. I'm still a bit confused after searching around for answers, so I thought I'd post a question here.

I planning to build a RX580 gpu rig, starting out with 6 gpu cards and 1x/16x powered riser boards. The RX580 has 8pin pcie power slot and is rated at 185W by manufacturer. I'm using a modular Corsair 1200W PSU with six 8-pin PCIE sockets and six 6-pin "peripheral & sata" sockets.

1. I ordered risers with 6-pin power connectors. They come with SATA-6pin adapter cable, but as far as I read I should not use those? Is it safer to use a PCIE power splitter cable, and connect the card/riser pair to the same pcie socket on PSU?

2. The cards are rated at 185W but 8-pin PCIE cable delivers 150W, is it safe to split the cable for both the card and riser? Is the riser supposed to deliver an additional 75W thru the PCIE slot on top of the 8-pin power source? In that case, shouldnt I power the riser from a different PSU socket because 8-pin PCIE is rated for 150W ?

Also, any other suggestions/tips on how to split the power among two PSU would be appreciated. Thanks in advance.
