I'm just flashing cards as preparation until mining motherboard arrives next week.  But I will use patch because want to see how much MH/s each card can do after flash. If i patch and restart after first card flash then I can just take another card from package and I don't have to uninstall anything to flash it?   Thank you.


Anybody know what memory timings I have to replace? 1750 mhz memory timings to 2000 Mhz and thats all? Or it depends on memory manufacturer??

Hello,

I have done research but still have couple questions about flashing gpu.
I do not have integrated graphics on motherboard is it okay to use RX580 with monitor during BIOS flash?

1. Clean W10 1607 64bit RX580 is already installed during Windows installation and monitor is using that card aswell
2. After W10 installation download latest http://support.amd.com/en-us/download/desktop?os=Windows%2010%20-%2064 driver​ and install
3. Restart
4. Download and install ATI Flash tool https://www.techpowerup.com/download/ati-atiflash/
5. Save Default bios to Desktop with ATI Flash
6. Open Default bios file from Desktop with Polaris Bios editor and change timing straps (not sure what timings i have to replace)
7. Save modified Bios to Desktop? In some videos people save modified bios file to the same folder where is ATI Flash Tool. Is it required?
8. Open ATI Flash tool. Load edited Bios file and then program.
9. Install patch
10. Restart computer and card should be flashed.

I do not have to uninstall anything between flashing cards? After first one just shutdown computer, take second, save bios, edit and program?
Any suggestions? What timings I have to replace on Sapphire RX580 8GB Pulse?
Do I miss any step?

All RX580 320€ are sold out now. There is a still possibility to get RX470 8gb, GTX 1070 and GTX 1060 6GB. Gainward 1060 6GB good option for 270 - 20%? I think I would go 7 of them. 1070 is good choice but 4 cards are not enough to mine ethereum. If 7* 1060 makes ~ 140-170? And I can also mine Zcash if etherum is too hard to earn.

Do RM1000x handle 7 RX470 or 6 RX580-s with motherboard and other stuff? Or should I buy 400W PSU for motherboard and connect RM1000x only with risers and GPU's?

Corsair RM1000X can power both combinations 7*470 or 6*580? I think will choose between them. Sapphire R580 Pulse 8GB or XFX AMD Radeon RX 470 8GB which has better cooler? I think 7*470 cards will make more noise? With 6*580 cards I have couple extra pcie slots to expand.

Any stable PCIe risers from China or Europe to recommend? SATA powered risers are not reliable?

You guys both mention 470-s to buy if we talk about eth. 1* GTX1070 can do about 27 MH/s or even 30. Then 4* 1070 can do about 120 MH/s Eth and we have 6* RX580 in same price range but they can do about 160-180 MH/s. Why should I even think about 1070-s? I don't get it.

470 takes less power than 570 and 580? Why 470 is good option?
I'm really confused. As beginner I thought about 570 or 580 because they are newer models(bigger power bills??) and maybe easier to sell gamers if mining world collapse.

Ofc. there can be availability issues. I would like to have backup option. Mixing different cards in same rig is not good option because of drivers issues?

Hello,

I will start building my first rig and can't decide what GPU's to choose. I live in Eastern Europe and prices are pretty high. Budget about ~1,9k €

These are not final prices, will get 20% off.
9* INNO3D GeForce GTX 1060 3GB Compact 2 - 210€ - 1890€ and 6gb card price starts about 300€
7*  XFX Video Card AMD Radeon RX 470 8GB - 280€ - 1960€
7* ASUS Radeon EX RX570 O4G 4GB - 280€ - 1960€
6* SAPPHIRE VGA PCIE16 RX 580 Pulse 8GB  - 320€ - 1920€ or 4GB model? 290€ per GPU
4* ZOTAC GeForce GTX 1070 8GB - 480€ - 1920€
GTX 1080 is over 600€ per card

Or something else?

Other hardware:

INTEL Celeron G3930
BIOSTAR TB250-BTC+ only with 8 PCIe slots for GTX 1060s have to choose motherboard with 9 slots at least.
4GB DDR4
120GB SSD
Corsair RM1000X? Something else in ~170€ price range?

Is Chinese PCIe risers trustable?
