MSI R9 290 starved

[Huginn]

I have 2 MSI R9 290's running on a Sabertooth 990fx and the bot one is fine while mining, but the top one keeps getting temps that creep up to 100. One time I didn't pay attention and my pc just turned off.

Is there a way I can set the top one to mine with lower intensity?

 

sgminer config file (without pool info)

 

"intensity" : "20",

"thread-concurrency" : "32765",

"gap-length" : "2",

"expiry" : "120",

"gpu-platform" : "0",

"gpu-threads" : "1",

"worksize" : "512",

 

"gpu-powertune" : "40",

 

"auto-fan" : true,

 

"temp-cutoff" : "95",

"temp-overheat" : "85",

"temp-target" : "75",

"scan-time" : "60",

"kernel" : "scrypt",

"scrypt" : true,

"failover-only" : true,

"api-port" : "4028",

"api-listen" : true,

"api-allow" : "W:127.0.0.1",

"kernel-path" : "/usr/local/bin"

}

 

So one fan is doing fine, stable at around 80-85°C, the other is being a pain. I'll end up watercooling them in the summer, but for now it's the stock cooler that'll have to suffice.

get some PCI-E risers, save your gpu's before they die -.-'

Had no intention of letting them die, turned miner off as soon as I saw those high temps. I already thought of buying risers, but is there no way to mine with reduced intensity on that single card?

i'm not into mining , but i guess you'd have to run 2 mining programs and run each off 1 card with different settings?

[Huginn]

"intensity" : "16,20","gpu-powertune" : "-20,40",

 

Figured the intensity out, but I have to put it at really low rates 14,7, so I'll buy a PCI-E riser ^^. Thanks for replying!

Okay, what do the PCI-E risers even do? Like, what's even the point of using them?

[Kyuubixchidori]

moves the placement of the graphics card, so you don't have them both right on-top of each other. Giving the both cards fresh air. Im guessing the second card is pulling in hot air. Moving them apart would fix this issue

It's more like this. They blow away hot air from the bottom, so the second card is getting hot air blown on him from the top card. As a result it's overheating.

Same question to both, since I have little to no experience with risers. http://azerty.nl/0-1216-625499/hicom-pci-express-riser-card.html, does this look good? Will I have reduced performance when not mining? I'm mining when I'm not gaming, but don't want gaming to suffer from it.

Holy hell you got a nice all-round rig...

not into mining (not worth it in UK) but if your cards are right next to each other...."there's your problem" but with that board im guessing they're not in which case get a 120mm fan aimed at thier intakes and turn town power tune as low as you can while still stable, power seems to be like "auto voltage" on motherboards where it can really affect temps by plowing in a load of voltage wether nessesary or not (my 7770 increased temps 5*c and that wasnt a power hungry card, didnt get more stable).

Airflow, Airflow, Airflow.

edit; post a side pic with the panel off.

Clear enough? Thanks for the response.

Quick edit: If I place my fingers between the two cards (to sense temp), it's really hot.

nice..

either they cant get enough cool outside air in, that case has 2 front fans but how much do they actually bring in? probably not a ton with those hard drive cages there, same goes for the bottom mounted fan, better than nothing but increasing its speed will lead to diminishing returns as it starts scavenging for air.

If it was me personally i would..

1-overlook my cards fan speed and power profiles, with power id run it at 0% power tune, it will likely cut off a few degrees and id increase fan speed in 5% steps to find the point where the noise starts to become annoying and set it so that it reaches that fan rpm during gaming load, id then set a temp maximum limit where if say the card got full of fluff the temp would hit amds rated 95*c at say 65% fan speed (cant say for sure, i dont have those cards).

2-see if i can mount a 90mm (or so) fan behind the hard drive cages close to the gpu's like you can with some nzxt phantom cases (dont like them but its a good idea) to make sure the air coming in through the front doesn't just stall in the HDD bays.

i'd probably have a fan profile like this obviously different because I dont know what those cards are like but have a 10*c wide point where the fan speed is constant and bearable at a temp that your comfortable with. its all about balance

and sure those cards may get a bit more air if they were spaced 1 more slot apart but i wouldnt worry about it, its not like theyre right next to each other, they can get some air still but im guessing there's not a ton coming in.

fwiw which is your hottest card? id guess the top one because cool air would come in the bottom cool the lower cards then the warm air would be blown out the sides only to be brought in by the top card making it run a few degrees hotter...

Not sure the nice is sarcastic or not, but hey! Thanks either way, and really appreciate the input you're giving.

I was mistaken, it's indeed the top card that runs hot.

I've seen that design too on the NZXT cases, I like the idea. Might ghetto mount a fan in the same position. The front intake fans are indeed not reaching that far, unfortunatly.

The top card runs about 15°C hotter than the bottom one, when idling. I'll fiddle around a bit with the settings in Afterburner, and for mining I'll just use 1 card then. Still pulling 875 KH/s out of it at 75-78°C.

It was serious, nice all round rig (see so many sketchy ones on here), might look into those cards

thanks buddy ^^ it's been a WIP for atleast 6 months now, but almost finished, just need to get a replacement h100i, since the pump died

Reason I got the cards was that 2x R9 290's are equal to 1 780 Ti in price (where I live). And the 2 will outperform the single 780 Ti. And they look quite good imo If you want to watercool, an EKWB worker confirmed that they're developing a waterblock for it.

[orangecat]

Possibly open a window to cool down the room they are in.

[Huginn]

It's a bit off topic, but EKWB will release a full waterblock for this card this wednesday! http://www.overclock.net/t/1474896/what-water-block-will-fit-my-msi-r9-290-twin-frozr/20

Will probably have to wait a bit longer until I can get my hands on one

I thought all the recent high-end MSI GPUs came with Twin Frozr Propeller Blade cooling, which is much more sexy and efficient than this?

[NInety]

They allow you to move a card out from underneath and/or above other cards for better cooling.

Nope, this is the "high end Twin Frozr", it cools nice, agreed. But the top card gets hot air from the bottom card so...
