Word of warning for those who are planning to purchase branded systems, specially Dell or HP workstations, specially Xeon processor. My only 3 GPU's (RX 480) are consuming like ~70 Watts each according to the GPU-Z, of course that it's not the right number if we take the wattage of the whole GPU, but still let's consider like 150 Watts for the whole card, providing me 27 Mh/s, haven't done very much overclocking, just a bit.

The system is consuming 400 Watts when not mining (in idle condition), and 800 Watts when mining. Meaning that GPU's are taking only 400 Watts and the remaining 400 Watts is being used by my Dell Precision T7500. Angry I'd not never suggest anyone to buy branded system, instead, build one. That should save lot's of power.

Please keep in mind that efficiency of PSU is also important. If your PSU is not efficient it might pull more from the wall than others. I do not think that HP/Dell put highly efficient PSUs into their Workstations.

Huh?
So many more factors to include in this.

You've got PSU efficiency, type of gpu, the way the rom is modded (power draw from the pcie cable or the slot (it makes a difference!)), the risers also pull some power, not every cpu is even efficient, same goes for the memory, etc...

According to WattTool topic starting post on overclock.net the most efficient mode is the default - when a lot of power is going from pci-e slot. Is it right?

Well, i will have a detailed answer for that either tomorrow or the day after as i'm testing that Smiley
Even if it's only a few watt saved. Less power is less power Wink

So at this moment, i cannot really answer that Wink

930w from the wall.
System : ~75w
=
855w

Split that on six gpus: ~142.5w per gpu from the wall @30Mhs

Still really good numbers. People should stop staring at gpu-z numbers because they are pretty much irrelevant.
The wattage presented in gpu-z is what the gpu itself are pulling, not the whole card.

The GPUZ number is 69W, the actual power consumption is 142W from the wall, or 125W for the card, so the difference is about 55W.

I am searching for an opitmized BIOS for Sapphire RX 480 Nitro+ 8GB (custom Card). I would appreciate if someone can help me out with this.
Thank you!


I'm getting some this week and I'll create a custom BIOS for them.

Well once you did it if you can share it will be cool Wink

Shall do when I've done enough to test it across all my cards and I'm comfortable with the outcome.

I would like to thank custom work XFX RX480 non-reference GPU's modded BIOS by Eliovp (Heliox)

6X GPU 182Mh/s, 63watt/gpu GPUz and stable more than 1 week (continuous operation 0-24)

So perfect job and perfect finish!!!

Thank you Eliovp  Smiley


wow - this is great results!

which rom did you use from Heliox?

Impressive 182MHs under 1000watts

He did not say 63watt/gp from the wall. It is from the gpuz. So the total wattage could be more than 1000W from the wall.

I think it is understandable:





impressive!

The wattage presented in gpu-z is what the gpu itself are pulling, not the whole card.

That is abut 4.8 J/MH. That is almost 60% better than the old generation R9 390 and similar to R9 nano.

I did some power tests last night on my PC which has 2 x 290x and 1 x RX480.

I was able to calculate the total power draw at the wall for the RX480 was 115~120w. GPUz GPU Power Only said 75w~

This is at 1120/2250 with VDDC at 0.925v, just fast enough to make 30mh/s.

6 x 120 = 720w. Add in a low power motherboard, CPU, RAM, SSD and an efficient PSU and I can see maybe even 820w being possible.

So to put this to test I'm just about to order six Sapphire RX480 Nitro+ 8GB and an EVGA 1300w G2(Alas, not the most efficient, but Platinum and Titanium PSUs are bloody expensive). Ready to build another rig Cheesy Targeting under 900w.

can you point me to the .rom File?


I'm sorry but this .rom custom work!

So not public share
please send me the link via PM

@pho130

63 Watt per GPU and in total with 6 Cards 930 Watt??

6 * 63 = 378 Watt

That means over 500 Watt for CPU, Mainboard, Harddisk, etc., that is a lot.


GpuZ it is different than on the wall. So actual power consumption: 930watt i use 1000watt PSU (Platinum)
