LTC config for R9 290:
On a reference cooled Powercolor R9 290 I came up with this as a "quiet" set up that allows me to sleep (55% max fan speed). tongue.gif
And it does an average of ~720KH/s w/o downtime, while feeding three displays, although in 2D mode.


Please note that in this image I started mining (02:13am) with the fan capped at 55% and when I woke up (about 7hrs prior to taking the screenshot) I allowed max fan speed to go up to 66%. Average GPU clock speed is about 941MHz with the current fan profile.


Here's what the batch file looks like:
Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://europe.mine-litecoin.com --gpu-platform 1 -I 19 --thread-concurrency 23552
The --gpu-platform 1 tag is necessary because I also have a GTX 680 set up in the rig.


GPU configuration:
vCore offset: -44mV [may actually go for less, was too tired last night]
GPU clock: 975MHz /effectively about ~885MHz after throttling @ 55% fan/
Mem clock: 1250MHz
Power limit: doesn't matter
Max fan: 55% for reasons stated above. About 65% fan should be able to keep the GPU @ 975MHz in an ambient temp of ~15oC.

That's what I came up with after about two hours of reading and fiddling.
So I figured I'd share with you guys. thumb.gif


Any insight? (Keep in mind I'm on reference cooling and that my head is ~1.2 meters away from the open case at night.)

Btw, an intensity factor of 20 is utterly unstable on my card, with this cooler at least. rolleyes.gif

 

I'd recommend buying an aftermarket cooler for that 290 when they come out. Give you some peace and quiet. :)

 

But I'd also thought I'd share in this thread that Litecoin is extremely profitable right now. (duh!) I'm making around $20/day after power costs with 1.5MH/s of power.

I will slap a waterblock onto it the very moment I scrape some cash. thumb.gif

You're telling me. First big payout has to pay for the cloud instances and a new windshield for the car. Got a gigantic crack going through it over the weekend. :\

Hold your LTC guys, it's making a mad climb past $25. Really need to make a dedicated mining computer now... the most profitable miner in my pool is making over 6 G's a month (hope you can manage 14 Mh/s)

Anyone know if there's a way you can monitor GPU temps and fan speeds from a remote machine? Other than using Windows' remote desktop access.. I feel it would be possible and very useful for cgminer to push that info online every once in a while and be accessible with an API.
