Ok, I will simplified for you. 750W Seasoinc (CM M750) 85+ is not enough for 3x R9 380, even all algos work fine, never had any problem? One more time, all algos except your no problem.

Let me simplify it for you. I could run 3x R9 380 on a 350W PSU if I only used it for light browsing and never mined. If you can't understand that more usage uses more power, then I don't know how to help you.

Hehehehe Wolfo or RobertD Cheesy, you are so funny, we are speaking about 750W not 350W, and in your case, your miner is pushing R9 380 VGA above 220W, which is VGA "harassment" hehehe. If you don't agree that 220-250W for one R9 380 chip is not to much, in that case you have totally wrong picture mate.

One more time PSU is not a problem, it can be 3K W unit, but VGA consumption is so high above real max manufacturer declaration, which will lead to GPU degradation, and at the end chip death!

OFF and OUT!

Stop embarrassing yourself Spacemarko. Grab a power meter and measure the load of the miner at the wall socket.

Each R9 380 takes 150W-300W at the wall. That's 450W-900W for the graphics cards + 50W-100W for the rest of the PC.
My guesstimate for power usage of this system at full overclocks is 700W mining Ethereum, 850W mining Ethereum + SIA.

You might want to also check the temperatures of the graphics cards. If you're getting such low profits, the cards a probably throttling down due to heat.
Please tell me that the 3x R9 380 are not inside a single PC case.

300W?! Robert, Robert, newcomer Smiley Cards are fine, cooling of the whole farm is fine. Wink We are not speaking about one single PC, we are speaking about 100 rigs (300 VGAs) in one farm (rigs not pc case). The problem is not with VGAs, the problem is that three PSU died, and VGA consumption is way a bow manufacturer max consumption. So please do not speak about PSU, we can take 2000W PSU in stead, but next step will be how to save VGAs from this miner who obviously is not designed to save life of VGA.

not all algos...try scrypt, or raising dcri in claymore dual miner (making the gpu core hotter-more power consumption) i don't own 380 but i have 280x, scrypt is an old algo and miners are already optimized for it.

i bought 850w psu (not 750w) back then for 2pcs of 280x so when i upgraded to 290 the psu can take it. and here comes the 390s, the 850w psu is doing the 2x 390 just fine now...

always have an allowance, know that in time you might be plugging a more power hungry gpu.

a gpu can only go as far as its maximum power consumption it is rated..let's say a 280x max power draw is 300w...no miner/software can tell that gpu to draw 350w or 400w of electricity. so always think of the max power draw a gpu and do the math when building mining rigs, choose psu's carefully (read reviews) etc. etc.

ETC+SIACOIN dual miner is giving more than LBC coin with AMD VGAs, even with woolf "special" miner, who I don't recompensed at all. After 6 month of mining, and just one week using woolf miner and LBC with R9 380 VGAs, my friend/partner lost three rigs, to be precise thee PSUs CM M750 burnout/dead.  Angry

LBC is nvidia's territory..specially now at low prices and higher network hashrate.

should have bought w0lf's miner early, dump mined LBC for ROI of the purchase.

your PSU is the culprit. don't cheap out on that.

I have better in development.

any stats?

buyers of previous version have discounts?

Well, the fact that guy doesn't know how much power his cards take with different algos (and more intensive miners) - AND the fact the dipass didn't upgrade the PSU on the last one after two others died of the same cause - hardly is my fault.

It is not your fault. Any miner have choice, to buy or not to buy your miner. All PSUs died at same day. And positive think is that he react on time, and save other rigs. Also your algo is killer for AMD LBC VGA lifetime, let face it. So we can speak about consumption, or what ever you want, whole day, but the fact is that your miner is making VGAs and PSUs to consume more power, and health of both components are in "dangerous zone".

I don't know how the 380 is but the 7970/280X when running them flat-out or Scrypt mining they can pull about 300Watts from the wall.

So using 3 of them with a 750Watt PSU is not recommended. I don't even think most 750Watt PSU have 6 PCIe to power all 3 of the 380 cards.



yeah i remember scrypt mining with my 280x's

choosing PSU for mining should put into consideration the highest power consumption a GPU can do...so you can switch to any algo anytime (worry free). the guy with 750w is fine with eth(dual miner too) but lbry miner(optimimized-higher power consumption too) put that PSU to rest.

Seems he isn't picked the right PSU's... I think these M750 is little outdated... Smallest PSU i use is 1200w and usually i have EVGA 1300w for every rig with 6x 280x or 5x 390... But i prefer to use 1600w EVGA in rig's with 5x 390... Maybe your friend has'nt think twice before get decision to use that small watage PSU's...

I always been curious about these 8 pack PSU's... Do they sell them in package of 8 pcs or what Huh What this 8 pack means ?

Mine PSU is better Cheesy


Yes when you say Grin. You have the power supply Leadex of 650-1200 W Tongue, compared to my Leadex Platinum 2000W (8 Pack). For my beast to be hydropower, your lamb can be powered with a bicycle dynamo Grin.

It was joke Smiley I hope next time you will realise that Smiley
