hi
I have just started mining with 5 x sapphire rx 470 nitro 8gb in windows 10.
here is the info of the cards:
gpu 1 : temp 74 c fan speed 38% , 109watt
gpu 2 : temp 74 c fan speed 40% , 106 watt
gpu 3 : temp 74 c fan speed 36% , 99 watt
gpu 4 : temp 74 c fan speed 38% , 106 watt
gpu 5 : temp 74 c fan speed 43% , 110 watt
my average hashrate is 128mh
Is the temp ,fan speed ,hashrate and the power consumption of the gpus ok ,or do i have to tweak(fan speed,voltage,...)
Thanks

at voltages can not help you, my rigs 470 4gb nitro run at 1870/870 1060/870- 50,58 degrees
I've had GPUs running for over 3 years like this without a single GPU failure. I have had to replace a few tri-x fans tho, and I definitely wouldn't say that was cheap.
Hey guys my are Rx 480s are doing 80W at THE WALL and 30.2 Mhs/s .. yeah sure they do.
SYSTEM WATTAGE(From Wall) * 0.94 - SYSTEM OVERHEAD(Control reading from wall) * 0.94 = GPU WATTAGE USE
Achieving this is very easy. You simply need to do some memory timing optimizations (With a hex editor and not just copying memory straps). Then a slight overclock on the memory on the memory from within the VBIOS itself. And most importantly ETH is memory heavy and not computationally heavy so you can under-clock the CORE drastically with 0 performance issues(This is where you see you major wattage savings). There is no need to mess with voltages. Anyone can achieve this. I can't wait to get 30 RX 480's to start playing around with them. This is also where the trial and error comes into place. Getting the memory clock as high as that card will allow while still being stable and then slowly reducing your core clock as low as you can until you reach the perfect mathematical balance for profitability between wattage and hashrate. On a typical card I may go through 30 VBIOS revisions to find this golden ratio because it is different for every card. There is no such thing as a "One Bios Fits All" solution. However, @wonderfullife I am not going to get in a troll conversation with you about my performances. When my RX 480's come in i'll do a custom rom for them and send it over to you and you can see for yourself (You mentioned you have RX 480's so that's why I said that model). Once I send it to you I sincerely hope it helps you increase profitability and have a "greener" mining operation.
@work I agree with you on the fan speeds, I have since updated my software AMDGPU-PRO-FANS which is available on github for linux users with an auto adjusting algorithm that uses wilder smoothing techniques to filter out random noise in the data so the speeds aren't constantly jumping around. After I've tested it for a bit I'll upload it to my github... With the auto algo it seems to like the fans at about 35% given the current temperatures outside. Thanks for the advice, it motivated me to work on my project some more that i had put on the back burner for a while. I look forward to pushing the commit to github for anyone using Linux and amdgpu-pro drivers. The current version is just the script that set's all the fan speeds to a fixed speed for all of your AMD cards. This new version has many more features so I think anyone who uses it will like it a lot. I wrote it in pure BASH so it is cross compatible across all versions of Linux.
@ober that's one heck of an idea!!! As miners we have to keep ourselves budgeted dont we
Some times the most redneck solution ends up being the best. I.E. I've seen people spend a lot of time building fancy rigs and i've seen rigs where cards are litterally hanging from zip ties on a $20 rack shelf from sams club. Post your funniest rig pictures below. I am an engineer so I dont have any "ghetto rigs" but perhaps i'll throw one together later today just for fun. I have 6 unopened rx 470, MB, memory, processor, hd, and platinium power supply sitting in a box upstairs so i'll have fun with this.
If you send me a better bios I'll certainly be gratefull.
Never had a reference blower fan die in me - those things are workhorses that never quit!
I was thinking about selling all my Tahiti cards before warranty expires, then this ZEC pump came and I decided to keep mining with them. Pure profit from already ROId hardware
Hi Haslux, can you guide me on setting up rig with Linux? thanks!
