StrangeAtoms

Looking awesome! Seeing how you set yours up gave me some ideas on how to improve mine so thanks! :D

Looks good, thats going to be one kick ass rig! I run my matrix 280X all stock clocks and volts, 720khs @ 99% load, 65% fans and steady 63 degrees celsius with ambient temp of 20 C.

Nice 8).
What would the temperature be like when you set up 3 cards per rig ?

nutnut has around 65@760khash if im not mistaken.
however he has the platinum edition with 1100/6400 stock settings.

platinum is on backorder…have ordered 5 of those to :P

What kind of Psu are you running for 4?

Congratulations on the new arrivals ;)
You setup looks nice. I too am getting inspired :P

How are the 280X compared to 7970 in regards to power efficiency? Are they to be preferred?

Ernesto

no this is achieved here :(

svennand

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

7970/280X gives about same hashrate and power consumption

[me=Calem]drools a little…[/me]

Nutnut

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.

So what is the reason to buy 280X then??

Nutnut

coz 7970 it now end of life

No point upgrading but when you are just buying more…

oooor you have 7950’s that you dont like:P

HizzleFizzle

Alright. Good to have a few more cards to choose from :)

kojima18

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

svennand

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.

im 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
