Topic: Radeon released RX 480. (Card is Released) - page 29. (Read 60193 times)
A R9 280x at 92 when mining is nothing unusual - it's just the card is a hot running card - and it probably thermal limits around 95ish.
It is actually 102c where it reaches thermal limits and shut down the computer.. tested it
I probably should have said "thermal throttles" not "thermal limits".
My R9 290 Sapphire Reference cards start throttling at 94, not sure what their shutdown temp is as I don't think they ever reached that.
Same here I have a reference card that stays at 94 constantly while mining and throttles down to stay at 94 but I noticed that the system reports the fan at like 40-50% only. Is there some special trick to make the fans go to 80?
Great news if this turns out to be right, 72 isn't too hot ...
He said later, "Room temp 2°C - 4°C, is winter here"

I'm waiting for july 1st when Discover has 5% cash back for amazon.
I'm beginning to wonder if not getting it day 1 means not getting it until half way into august. I may have to just buy it right away

I can see the newegg prices right now.
As of right now the newegg prices are $239 to $269 for the 8gb 480 version on newegg.
There is only one 480x - 4gb card for $199 on newegg. I see a few 4gb cards for $239.
Newegg usually sets the lowest price for GPU's when they are released. I expect the $200 cards to be limited supply and sold out quickly.

waw 28mhs for $200 card?
price levels will be really dump later, and so many gamer will be angry of that
no this is producer (amd) price.. price levels will be really dump later, and so many gamer will be angry of that
Real retail price will be about $250 or more I guess..

Great news if this turns out to be right, 72 isn't too hot and almost 30mh/s is great for $200, I can't wait to see the vega cards as well, we might be seeing 50mh/s for 250w per card. Koody Member Posts: 11 ✭

If that is true, the 480 RX will be sold out as soon as it is on sale. I will order a few of the 480 RX. that is very good.

The product is Still not on markets and i am still waiting for that. And waiting for review

Sounds great! Does he provide any screenshot? And if is it overclocked? I wonder what will be temp in rig by 6cards (i suppose it is much hotter) Koody Member Posts: 11 ✭

How many people running 90c temps have good computer cases on?
Some cards run hotter, even with massive airflow through the case.
R9 290, R9 280x, and especially the R9 290x were notorious for running hot - and lasting a long time anyway.
My triple-box with 3 R9 290s (Stilt bios, dropped temps a LOT then I overclocked and brought them back up some) has 2 Delta 120mm 250CFM fans in front, the 4 stock 200 (220? 180? something crazy-big) fans on the side, and a low-flow 140 in the back I couldn't find a good place for. My 290s run anywhere from 75-85C even with THAT airflow at 90% fan setting and space between them - but they're also pushing 1060-1100 Mhz core clocks and that's in a room with ZERO a/c and decent airflow, but still pushing 95F inside-the-room ambient temps the last couple days (heat wave seeing highs around 90).
My older HD 7xxx series cards I can generally keep under 70C, the various NVidias I set target and custom fan profiles on to keep them under 75C - the 7750s are an extreme, they all (except the Sapphire with it's GOOD original fan) have Delta 60mm screamers twist-tied to them and never see 60C.

We must admit that for etherium mining rx480 is just tonga (380-380x) moved to 0.14 fab and with faster 2000mhz memory.
With slightly lowered power consumption.
Tonga 850/1650 with samsung or modded bios elpida mem can do 24mh/s with moderate power draw, so 28-29mh/s with 2000 mem is not a surprise.

I was reading on the Ethereum forum that one of the folks who was testing one of the rx480's was stating that the GPU temps are running really hot, like 89c or something. That is a concern. I hope that isn't the case.
My 280x is running at 92 now while mining.. I see no issues with it..
The above is key information for the following issues:
1) In going from "28nm" fab technology to "14nm" fab technology, the the chip area has shrunk by about 1/2 to 1/4 of the area of a roughly similar 28nm fabbed device.
2) Say you have a 100W chip. If you shrink its area by half and everything else is the same, the amount of thermal energy per unit are that has to be dissipated has doubled. The problem is that you may have to use a technology such as water cooling to handle this increased heat dissipation per unit area. The thermal heat transfer properties of passive radiators using metals in conjunction with thermal grease have their own limits in
terms of how much heat flow they can sustain.
good point, may wait a few more days to see more testing results for the x480.
yeah 90 deg wont cut it at 14nm, maybe he was running bad fan profile or something who knows

I found with my PC case I had to remove the side cover and direct some fans at it to keep the 390x's from going nuclear and melting a hole through the floor! ROFL So the RX480 or possibly RX490 are prime candidates to replace those 390x's.
If your going to run these in a PC then the low power consumption cooler cards are a must IMHO. Had I known what I know now I would never have gotten the 390x's and would have kept my focus on the low power and more efficient cards. Not just for the power consumption, but also for the summer heat. Trying to keep things cool is a challenge.
Longer term as profitability dwindles for coins like Eth, those who will be able to continue mining the longest will be those rigs with the greatest efficiency. There are a lot of GPU miners right now and as Eth profits dwindle they will begin to flood the other alt coins and things will probably get pretty grim for GPU mining for some time. So file that way in the back of your mind that the time frame for profits may be short. Plan accordingly.

I've never mined before, but neither have I gotten over 75c with my case that gets good air flow, very well optimized air flow at that.
