How is my new baby?
Nice!!! I like it!
What are the difference when the upper fans turned on or off in temperature?
I was wondering to do that but not sure of the results, as every fan I put in my gear no matter where, it only make it worse.
This rig is a beauty. planning on building something similar. just two questions:
- You used two mobo on this rig. does that mean they are connected to two monitors?
- If they aren't, how do you connect both mobo to one monitor?
One at a time, get one set up and mining then just unplug the monitor and plug in the second computer. You don't need a monitor to mine.
How do you tackle the GPU's going idle? and also what PSU do you use? and how many PSU do you have installed per mobo?
They don't go idle, dealing with that problem hasn't been an issue for a while due to newer drivers. A single 75 ohm resistor in the right place is enough to "dummy" a GPU into running, otherwise.
What PSU? Any will work, though I suggest you spend money here. Cheap power supplies will cost you more than they save up front. Running two or more per motherboard is not a problem, depends on the PSU prices and line voltage in your area as to which would be the best/cheapest choice (1 or two PSU.)
Line voltage in my area is 240v. What do you think about using Enermax platimax 1500W per mobo? Also on close lookup at your gpu, you didn't use any ohm resistor.
I think Enermax makes a good power supply, here in the US I tend to use Corsair, EVGA, and occasionally cheaper supplies. If it is a good brand name it should be OK and capable of it's rated wattage. Cheap no-name power supplies often can't supply a steady wattage close to their rating, sometimes as much as 20-40% overrated in my experience.
You should try to load the power supply no more than 85-90% full, your mains voltage being 240V means you can probably run 5 250W cards on one PSU. Here in the states line voltage is 110V and generally 15A, so most power supplies are made for 1200W max, or 110V x 15A = 1650W - power supply losses = 1200W so no 5-6 GPU single PSU rigs. If your line voltage is 240V and the circuit can handle 8-10A (240Vx8A=1920W) you should be OK.
I do not have resistors because I do not need them, even in linux.
