R9 280X Buying Advice

[Nullu]

I'm looking at purchasing an R9 280X for mining. Any advice? Any cards I should look out for? Any to avoid?

Any advice would be much appreciated. I'd hate to make an impulse purchase and end up with a lousy hashrate. I plan to add one more in the near future also.

I am using 2 x Asus R9 280X and very happy with them. Get a hash rate of 720 Kh/s each and temp of 72%, not pushing it too hard and doesn't make too much noise. Using a 12 inch riser cable with it.

You can't go wrong with either sapphire or asus.  I have 2 rigs with 4 asus 280x each which gives me 3MH per rig and its very stable.  Just make sure you get a good PSU.

asus r9 280x directcu ii will give you and easy 750kh/s. can do 740-750 range with 60-65% fan, and not get above 72c, but i'm sure this all depends on ambient room temp.  not sure how they'll do in the summer months. 

runs smooth at 770-775kh, in the high 70c's range, but need the fans cranked up over 70-75%.  fans are NOISY when over about 65%, so i turn it all down to lower the db level.   once i get it all moved out to the garage, i may just crank em up and let em run. 

giant cards- like 2.5 slots each, so if you plan on running more than 2, you will need risers.  try sticking more than 2 on a board and they're too close together and cooling could be an issue. 

like stated above, a good psu is a must, as they suck up the juice.

other than the noise, they are solid cards, and at this point i wouldn't consider any others for my rig. 

now to find them at a decent price.  lol  i got a couple "on sale" for $329 each.  currently $419 on newegg, but in stock.  yikes!! 

just my experience.  YMMV.

buy cheapest reference 280x such as PowerColor, then replace with water cooling you will get ~850 kh/s easily

I'm happy to watercool, so will only get a reference design 280x anyway. Everyone seems to be happy with the Asus cards, so I'll get those and watercool them.  

Maybe get a fan controller and stick a nice meaty 1080 rad outside my case.

Edit; how about; http://www.overclockers.co.uk/showproduct.php?prodid=GX-225-MS

Reference design. Price seems decent. What do you think?

I am also considering buying 280x ones for my setup. What do You think about Gigabyte or MSI cards? Especially Windforce edition?

Got proof? haven't seen a 280x  770kh/s personally...I'll watercool my rig soon, so it would be really nice to get more than 800.

I am running msi/his/asus v1 and v2 280x

Asus performance for me is nice and is the card that I have used for the majority of my systems.

I've got the MSI Radeon R9 280X OC and I've had no problems with it..
If I'm honest, I struggled a bit getting it set up and running at 740-750 khash/s because when I first put it in I got 580 khash/s average.
Although I am running it on the same board as my NVidia GTX 770 and that was probably one of the biggest contributing factors to the problems I had.
It's got the default cooler on and running at 75°C average with the fan at 100%.. Honestly it isn't that loud (no where close to as loud as my 770 at 100%).

Here is my config for when you get it:

Code:

"expiry" : "1",
"hotplug" : "5",
"no-submit-stale" : true,
"queue" : "0",
"scan-time" : "1",
"scrypt" : true,
"shares" : "0",
"gpu-threads" : "4",
"gpu-dyninterval" : "7",
"gpu-engine" : "1080",
"gpu-fan" : "100",
"gpu-platform" : "0",
"gpu-memclock" : "1500",
"gpu-memdiff" : "0",
"gpu-powertune" : "20",
"gpu-vddc" : "0.000",
"intensity" : "13",
"temp-target" : "75",
"temp-overheat" : "85",
"temp-cutoff" : "88",
"temp-hysteresis" : "3",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "0",
"shaders" : "2048",
"thread-concurrency" : "11200",
"no-pool-disable" : true

For some reason it is important to run it at 13 intensity and OC it to 1080. Anything above and I lose khash/s exponentially.

What is the power consumption of the asus or sapphire?

Any major brand is good, If you haven't heard of it then don't buy it.
Personally I run 6 MSI R9 280X on one single board, each card is pulling roughly 700-705 khs.
After adding the fourth + card I have to restart the machine once every few days or the khs will drop to around 650-675 per card.
Settings are key as well if you choose msi then I can help!

People can complain. but I use GUI miner with updated files and config.
It works fine for me, you can pull up cgminer and you will see the estimates are accurate.
Currently running two 7970s MSI as well. Cannot get the right settings for the life of me, both hashing at 700khs.

Cards are all around 75-80C I cool them with two box fans one in and out the in has a custom built air filter i placed over the front. Run in my furnace room so its mighty cold.

Asus, sapphire, xfx(sometimes), MSI, are the top brands i think.. In no order

Running 1 rig with ASUS cards right now and super happy with them.
