Yes Lonerangir , that's it!
Thanks Phil but I don't want to change my case or fans, they are average gaming quality, and I just want to make profit of the PSU when not gaming.
That's why I added two R9 290 got for cheap but don't want to proceed deep changes on this unit.
Being able to manage heat and noise would be very appreciated for the time we are near the computer ! (at the moment , I just can stop mining instead)

NB : I'm currently with genoil ethminer , but will try claymore soon

NB bis : good idea for the silverstone Phil, I might take the one I have on my silent S3 to improve computer for free and without lot of work.

to try another method. strip out the drivers.

put in 16.7.1 go to watt man and set the power to -30 or -35 it should help you mine lower heat noise and fans.

or not since I only tried it with rx 480s and claymore .

worked really good for them.

Guys,

To connect second R9 390 should I simply plug it in and connect to PSU power output?

Or do smth with CrossFire?

Thank you!

anybody using deepcool quanta dq1250? any comments?

http://www.deepcool.com/product/powersupply/2014-02/10_796.shtml

bought a brand new at a huge discount, only 145 $

5 year warranty 145 usd seems to be a good deal.

it is two rails 1 is 45amps the other is 65 amps

http://www.deepcool.com/product/powersupply/2014-02/10_796.shtml

click output to see this

AC INPUT     VOLTAGE   CURRENT   FREQUENCY
100-240V   15.0A   47-63Hz

DC OUTPUT   +3.3V   +5V     +12V1    +12V2   -12V   +5VSB

CURRENT(Max)   25A     25A    45A     65A      0.8A    4A
OUTPUT(Max)     150W     540W     780W     9.6W   20W

TOTAL OUTPUT   1250W

so proper setup for more then 4 cards may not be possible or at least tricky

I think he's looking g for a way to throttle to mining app. Do any of the miners have a command line switch to artificially limit the hash rate? A way to not just run at 100% capacity.

Personally I have used Seasonic and EVGA PSUs.... but I saw a good deal for Corsair PSUs (used for a month AX-1500i & brand new HX1200i) and want some feedback before I invest one or two for my next rig.

Reason for me to consider other brands is EVGAs are expensive and I wouldn't mind using it for high end GPUs. But I am setting up a rig for the recent 370s that I got cheap from a friend, and would not want to use an expensive PSU.

do you guys know a way to reduce GPU usage while mining with home computer ?
The 2 gpus family computer run at 76°c with almost 100% fan (less than 100% fan make heat go up).
Power limit 50% or less voltage -100mv do almost the same : -100w but not less heat and no less noise ... (but -100mv doesn't reduce hashrate , power limit reduce it)
Any advice ?
The 2 R9 290 provide 50mh/s hashrate , I would agree with a light reduce of hashrate if it can protect my ears !

you have 2 290's in a pc case correct?

what are your case fans?

what is your case make and model?

what do you mine with claymore qtminer or another?

case builds do run hot.

better case fans help a bit.

if you can get 2 of these in the case one as intake and one as exhaust they may help

I've had VERY good luck with Seasonic over the years, especially their recent "X" series.
When they DO die, they tend to get it out of the way VERY early on then last bloody near forever - or they get hit by nasty surge stuff when they're VERY old and finally bite the dust.

My EVGA experience is minimal, though I did run some of my S5s from a couple of 1300 G2 units that have had no issues.

Both Evga and seasonic have been pretty good good for me.

I have been using this psu for 2 and 3 card builds.
http://www.amazon.com/SilverStone-Technology-Strider-Titanium-PS-ST70F-TI/dp/B01CE7NUIU?
my 2 card build is a r9 380 + a r9 390 hash at 45mh uses 350 watts
my 3 card build is 2 r9 390's + a r9 nano hash at 77mh uses 630 watts

undervolted to -100 or - 75 for the 5 cards

so two pc's total 122mh and use 980 watts

I actually recycled the Seasonic and built a i5 gaming system with GTX970 for my son - no issues there and still going strong.

IMHO, a rule of thumb is, for a 5 or 6 GPU rig, is to get a decent 1200-1300w PSU that is above the "100$" range and Gold (at the least)... above that, very good and reliable - nice to have - like Platinums but horrifyingly expensive.
I think in the next few months, with newer GPUs (490?) with low power, I don't think we need to get more than 850w or 1000w.

I got a few of those EVGA-G2-1600w early this year... no.. I wasn't crazy, I was just celebrating my very first solo block reward at solo.ckpool and with the help of kind members, I built my very first "1520w 5x390s 150MHs" ETH rigs.

I used to use Gold power supply. But all my new rigs are built with Platinum power supply to save 2% energy.

I've been following your thread for a while... thoroughly enjoying it!

I've been researching different cards lately and and looking forward to the 1060 (July 19th) and the 470 (release info coming soon). I hate to wait haha

Good luck guys with your RXs , they seems to be complicated ...

In the same time , I'm looking after the Stilt Bios.
Informations here :
https://litecointalk.org/index.php?topic=12830.msg121827#msg121827

And files here :
https://drive.google.com/folderview?id=0B2XVfIhkHZlfcVR0QzhlQlhJYTA&usp=drive_web#list

I'm just not sure how to choose the good file for the 290.
As it seems to be the best choice with ethereum, I would like to take the bios with less voltage, but not sure to understand which one it is from the list here:
https://litecointalk.org/index.php?topic=12830.msg121827#msg121827

I think this one is with highest voltage : MBA_C6711101-100_K2_AGR_STILTMP_V34.zip (DPM7 - 1.2250V)

and this one the most undervolted : MBA_C6711101-100_K2_AGR_STILTMP_V48.zip (DPM7 - 1.1000V)

Could you guys confirm you understand that as me ?

You need to try each one going from lowest to highest voltage until its stable. One of my 290 is very stable the lowest voltage, another one is only stable at the highest voltage. Check your ASIC quality in GPUz

Thanx for trying to help.
For my home computer , mining with two gpus , I would like to get the less noise possible , so I need the lowest temp , that imply lower voltage I think.
Could you confirm my understanding in the reading of the files name ?
=> MBA_C6711101-100_K2_AGR_STILTMP_V48.zip (DPM7 - 1.1000V) is the less voltage available.

For the mining rig ,(whose noise is not a problem) , I'll do as you suggest to try to get the best hashrate.

this one is on the way

http://www.amazon.com/EVGA-SuperNOVA-PLATINUM-Crossfire-Warranty/dp/B010HWDPKW?

this will be a build to put into my friends shop in the brooklyn navy yard

an i5-2500t cpu used ebay = 100
a new mobo http://www.provantage.com/gigabyte-technology-ga-b75m-d3h~7GIGB0HU.htm = 75
an old 2.5 inch hdd = free
a old pair of 4gb ram sticks = free
the psu above = 100
windows 7 = 25
case = http://www.provantage.com/corsair-cc-9011056-ww~7CRSC016.htm 60

335 + 2 r9 380 cards = 750 will do just over 40mh at 340 watts he has 8 cent power but we will just split coins.

follow up i turned off the r9 390 pc and I am running just the rx 480 pc with 2 480s.

i show 45-46 mh in house

but at the pool the line shows the hash and no credit or miner

you can see the r9 dropped off
you can see the rx pick up but i do not get any credit for it.

this is happening on 3 different pc's all windows 7 with the new 16.6.2 and installed

Phil - are you using qtminer?

Try changing to Claymore. I was using qtminer before then changed to Claymore, and working fine at ethpool.

I forgot to give you credit as I did just that all is good now!

Ah... that's great news!

I was worried for awhile because, I have 12 more 480s coming my way to get 2 x 6 x GPU rigs up this week.

Claymore Dual Miner (CDM) has so many cool switches that you can configure it to kingdom come.

I have also suggested a few features in his solo-mode and monitoring utility, in which Claymore has incorporated in his latest versions.

If you go to the Claymore thread, many members have contributed the many cool features the v4.7 have today.

Also due to lack of OC and underclocking support for 480 (I can't get AF or Strixx working with it), it's worth looking into CDM's features that does these power controls from CDM command line.

You are the people (miner) who drive up the mining difficulty. You must have very cheap electricity.

I deleted your post it does not belong here. Here is why: " the sky is blue " obvious correct? yes it is obvious. and that means you were making your post count bigger for your signature.

I use EVGA-G2-1300s, 5 x 390s no issue for ETH mining only (1290w~1350w) with -100mV undervolting.
6 x 390s will be a stretch for the G2-1300 but the G2-1600 can handle them easily with -100mV undervolting.

I find the EVGAs very reliable compared to the previous PSUs I use, Seasonic.
