16.12.2 drivers do not support modded bios. I have found patch only for 16.12.1. Have anyone seen patch for 12.2 or for 17.1 ver driver?

Guys. how much H/s you get with your RX 480 8GB?
50% load sweet spot? That can't be even remotely true. I agree that having some headroom is good but running 1600w for 800w load is just not a thing.
Why can't that be true? Because you've never heard of it? 50% - 70% is usually the best efficiency for a PSU. Depends on the PSU and curve. 85% or less is recommended for a longer life-cycle. I always aim for ~50% load on PSU understanding that demand usually increases.

Edit: And I currently have an 800W load on a 1600W PSU. So I guess it is a thing.
You are correct with the around 50% sweet spot, but the difference in the efficiency is so negligible that I wouldnt bother with it.
Personally I am fine with 90% load of the PSU.
You also need to remember that 1000 is the wattage PSU can dish out to PC, so 90% load will register as around 990W at the wall.
Every PSU with a certificate should be browseable on this site: (I am actually amazed how this site is not common-knowledge by now)

This link will take you to corsair PSUs.
Now lets take a look at RM1000i efficiency curve: https://plugloadsolutions.com/psu_reports/CORSAIR_RPS0010%20(CP-9020084)%20(RM1000I)_1000W_ECOS%204336_Report.pdf
As you can see it stays pretty much constant.
i use 295x2 to mining, now hashing at 560 sol, this normal?
I'm afraid so. Im currently working on one and i have a hard time getting it above 300 sol/s per GPU.
I got it up to 306 now. With claymore V11 -asm1 -i 5
Clocks 975-1375 @ 1.105v
Memory timings are 1250MHz strap.
15.12 drivers (still having problems with newer drivers mining software just crashes after a few sec)
Timings did the trick to kick it +20 sol/s per GPU higher.
Voltages are bios modded card seems game stable so its not at the stability limit for mining.
But somehow these cards wont go as fast as the 390X. I also think 290X with different Hynix modules and Stilt timings would do even better.
When i test oclmembench im at +- 250Gb/s a 7970 with stilt timings does +- 230 with 1375Mhz. And those cards do +- 270 sols with 1000-1375 MHz.
ASM is more effective for those cards tho. Without they would do 235-240.
Only thing i can do now is do the 390X MC bios MOD but i have to do a lot more reading on that. Not that simple to do. Took me some time to figure out the timings but thats easy compared to the MC mod.
i use 295x2 to mining, now hashing at 560 sol, this normal?
that seems to be low for 2x290s a single 290x is over 300 solsDid you do the mod yourself? or did you download a premade bios. I have seen those for the 290X but not for the 295X2. Not enough people owning those cards.
I do not have experience with the 295x2, but I can image you hit the limits faster than on single cards.
My 390s (non-x) are all running average above 360 H/s with OC and stock BIOS.
And yes - my modded 290X was even doing 380 H/s (!) - and also cooler than stock. I now reduced the clocks for stability as it's the primary card in a workstation, but it's still at 355-360 H/s.
I dont know Cooling is not the issue. Power delivery is also a non issue. It really seems to be localisations of the memory timings and controller.
Thats also what makes 390(X) cards so much faster then stock 290(X) cards. With a bios mod they are just as fast.
Seeing the stock hash rates compared to my strapped bios makes me think there is even more to gain.
Im currently underclocking the core but thats because i only have a 1000 watt PSU in that system. And it needs to run 5 GPU's. Stock the system with the 295X2 mining solo (other cards where connected but not mining) was already pulling 524 watts from the wall and with all cards i was hitting 1024watt so optimizations where needed. Core voltages stock are 1.25v way to high if you ask me. I got them down to 1,1v with a clockspeed reduction of 45-50MHz. (stock 290X is 1.2v if im not mistaken)
I might optimize the card more if i have time. But i only have 1 so the gain is not that big. Its mostly for fun
Can someone tell me the Max power draw for a stock Rx 480 4GB? Trying to figure out a PSU for a 6 x 480 rig.
Use nominal values from datasheet for this purpose (=150 W) and add proper headroom for overclock, spikes and working point at good efficiency.So a gold rated 1200W PSU for 6 x 480 + MB with Celeron-CPU and risers/SATA should be just fine in other words. Even without undervolting.
It is better to make farm with a reserve power supply for future algorithms, which can be more demanding. This is usually done so, it is considered necessary power of consumers and mount a 20% of the stock. 6 cards x 150 = 900 + 100 (system)=1000 + 20%= 1200W will be good.
Ok, going for EVGA G2 1300W to be safe. Should set my mind to rest.
The 1300G2 is an amazing PSU but it only has 6 6+2 pin connectors and 2 6 pin connectors, if I remember correctly.
Correct (I have 20 of them). There are 6 PCI cables. All 6 have a 6+2 pin connector, 2 of those 6 *also* have another 6 pin connector.
I have an 850 G3 and 1000 G3 coming in on Thursday. I can report back on my experience pushing furys. You may be able to find a deal on 2 850s for close to the same price as a 1300 G2. Or pick up vga splitters.

Here are the results after a few years, still very stable.
Basically the 7970 and 280x are faster or just as fast as a stock r9 290.
I had to revert the r9 290 back to stock clock since it started locking up at 1050/1450.

Can someone tell me the Max power draw for a stock Rx 480 4GB? Trying to figure out a PSU for a 6 x 480 rig.
I figure on the high end, about 150 watts, though from what I understand, it's much lower, figure 125 watt max while mining. In theory, you could do a 1000 watt psu, but that's pushing it. Def a 1200 watt psu to have some headroom.
Rosewill Capstone below for just $110 before a $10 rebate. $100 out the door for a 1200 watt psu seemed like a good deal to me, so I went with it, though haven't used it yet.

Would be too close for me. To max out the cards under all conditions my bet would be more at 1600W. You do not want to run the PSUs the whole time at nearly full load, even if it might work for a surprisingly long time with high quality models.
But that's one of the reasons I don't build rigs with more than 4 GPUs. It's much better to handle while having a greater and cheaper selection of components.
1600w? Their max TDP is like 160w, how can I get to 1600w with 6x?
It will not consume 1600W, but it would be a good choice for the PSU size:
Load working point of the PSU. Sweet spot of a gold rated one is around 50% load. So if you run it between 50 and say 75% you will have nearly highest efficiency, stability, reserves, lifetime and no thermal problems. From the technical view this would be the right way.
But if you like you can also use a 1000W PSU for a 1000W load. Should work on the paper. Maybe. For a more or less long period of time. As I said, I already tested a lot and I will avoid such combinations in the future.
And don't forget it's 24x7 load.

Hmm... Seems 280x got a massive speed increase, but my 285 is still at 165, vs 260 h/s from 280x. What's up with that? Otherwise, my 390 is ballin' at 355 sol/s and RX 480's are looking great as well!
R9 285 was one of the VERY FEW actual new GPU chips AMD added vs the HD 7xxx series to the R9 2xx line.
It has very little relation to the R9 280x or R9 290 at all other than process and timeframe of release - it's actually more of a R9 3xx precursor, as it supported one generation newer version of GCN than most of the R9 2xx series cards.
Yeah the 285 is basically Tonga crap like the 380. They were never good for mining but were a slight improvement for gaming with less power consumption. They generally have a lower base core/memory clock, and much less memory bus width.
With Tonga's your best bet is ETH since you can get around 20MH/s out of those.

I had my 470 4gb run at like 200watts before. This was one with very bad ASIC quality, ETH+SIA dual mining, under stock voltages.
VRMs were cooking at like 100C.
SO yeah they can use huge amounts of power if you don't under volt properly.
