Finally the Asus Matrix 280X has arrived! at least some of em
-
no this is achieved here :(
-
i use seasonic x1250 for all my rigs now:)
according to my wattmeter one rig with 4x 280X uses 1300w
withdraw 150w for system and it shows that each 280X use 287,5w -

Congratulations on the new arrivals ;)
You setup looks nice. I too am getting inspired :PHow are the 280X compared to 7970 in regards to power efficiency? Are they to be preferred?
[/quote]7970/280X gives about same hashrate and power consumption

[me=Calem]drools a little…[/me]
-
Yeah - i run the platinums. Nice thing is that the stock clocks are 1100/1600 so to run the best settings (1100/1500), i have to UNDERclock the cards! ;D
765KHs ~75c at ~60% fan (1800rpm). They are nearly silent.
Only running 3 per rig though as i cant find any damn x1250 PSUs in the UK. Had to settle for a x1050.

[/quote]So what is the reason to buy 280X then??
-
coz 7970 it now end of life
No point upgrading but when you are just buying more…

[/quote]oooor you have 7950’s that you dont like:P
-
Alright. Good to have a few more cards to choose from :)
-
Scarcity… so hard and overprice the 7950 are right now in Europe at least.
-
So pc crashed about 5 hours after running those settings. Running again to see if it was a fluke
-
Found out that those cards do NOT like to be stacked in height. most of the air gets pushed out the side of the card (up). with a plate above the air gets really trapped.

Thread 4: 375.9 Kh/s Enabled ALIVE
Thread 5: 373.7 Kh/s Enabled ALIVEim pleased with this. will continue my expansion of having 4 280X rigs with three card each.
should yield 9000Khash
On top of that i have my old rig of 4x7970 + 1x7990, which should give me an extra 4300khash.
Oh and i have two spare 280X for an small rig that also hosts my 67 asicminer block erupter usb’s so that should add another 1500khash.
By the end of the day i should have a total of 14800Khash scrypt power, and 23Ghash of Asic power.
Think i gotta stop then (unless i get myself a cheap caravan for better cooling/mining solutions, then i can set up technical power from house and have better cooling)
told the misses earlier today, she wasnt that happy tbh ;D -
Haha, rock on, svennand! Veldig festlig! ;)
Are you racking up diesel generators out back as well? 8)By the way, maybe the “CoolerMaster Silent Pro M2 1500w” would be interesting. I guess you could cram 5 video cards into one rig with that bad boy, right?
The description is “Silent Pro series is a single rail power supply from Cooler Master that’s addressing a growing market demand for powerful single rail PSU. With up to 50 A on the 12 V rail, the Silent Pro series delivers where it counts and won’t have any problems powering even with the most demanding SLI or CrossFire systems.”
In Denmark it costs 2,251dkr (412$), so it’s not cheap, but CoolorMaster usually makes good products (from my experiences with their CPU coolers), so it seems resonable.

[/quote]Well their lying, according to the spec sheet of that psu it has two 12v rail, one that handles up to 70A and one that handles up to 55A, which means 840w + 660w.
That just gives me goozebumps in the wrong way.
My cards consume around 287w each, so i could fitt 3 of em on the one 12v and two more on the other 12 volt.
Also you would have big difficulty getting 5 cards with enough spacing on one rig, all the cables WILL be to short unless you are able to place the psu in the middle of them. hows that for a cooking… ;)A word of advice, dont skimp on the PSU. Seasonic X1250 ftw! i just love that psu, able to drive 4x 280X clocked at 1100mhz core and 1.256v (standard) on a single 1250X.
Been running the same setup with several rigs of 7950 and 7970 without one single hickup that was the psu’s fault for about 6 months! -
Hmm… odd that the CoolerMaster is marketed as single rail then. But I found it on the American website and see the same specs you found, so I’ll stay away from that.
Actually, the Seasonic is cheaper as well, so it’s no problem.
By the way, by pure luck, my choice of PSU was the XFX ProSeries Black Edition - 1250W. Only thing unlucky is that the Seasonic would, again, have been cheaper… I’ll order one of those when I get money back for the ASUS 7990 that I’m going to send back to the shop tomorrow. That thing is just too hot. I don’t think there is any way it would ever run cool enough without water cooling or something equally radical.

[/quote]luckily the xfx is a the same psu as seasonic, just with a shittier fan.
still not a bad choise:) -
Woke up today to a smell of really well burned plastic, i was like NOOOOO!
Went down to the basement and was like a narcotics dog, sniffed all the cards but couldnt locate the source.
Checked my monitoring app to see that my 4x7970 rig was down, so i started investigating it over and over. everything seemed fine and i restarted it back up (phu, it wasnt one of the 7970 cards).I then realized that that burning smell came from the ONE bad PSU i got (apart from the Enermax), A one month old Corsair TX750,
that construction consist of a mini atx mobo with amd LOW end processor and 1ram+128gb ssd and two 280X.
Sooo powerwize i should be fine! Apparently not…Will see if the burned smell goes away. but im ordering a Seasonix X1250 as we speak cause that Corsair gotta go!
-
Ouch man… That woulda been a short period of panic followed by somewhat relief.
-
had to move stuff around and reuse my Enermax 1500W that had been collecting dust. So now that one runs 2x 280X and the shitty Corsair one will be running 1x7970 instead while i wait for replacement PSU.
Was gonna order me more 280X cards today, but my god the marked is completely sold out of ALL 280X disregarding brand/shop! amazing :-\
-
if the PSU was the source of the smell(got fried) how did you manage to turn it back on?
or is it that it just overheated and melted some plastic without actually damaging its board/components?from the moment i started mining i have this anxiety and fear of burning my rig :-\ . hopefully that day wont come.
