Ahhh, I had no idea. I just checked and it is legacy! I found a guide here (http://windowsreport.com/install-windows-10-using-uefi/) and I'm familiar with Rufus so I'll give that a bash when I get time.

Thanks a million for the help - I'll let you know how I get on

How do you find the 170 then? Lot of people slagging it off from what I've read

open the run thing and type msinfo32.. on that page look for bios mode.. If it doesn't say UEFI (it's uefi or legacy) then you need to reinstall and 7gpu (maybe even 6gpu too) won't work (there are guides to install the uefi version you may need the rufus program)

I have to reinstall windows 10? I've never read that anywhere else.

Can't see any settings in my BIOS for pcie lane timing or peg0/peg1. I set pcie to gen1 but no difference. Just get spinning fans a few times while the PC tries various configurations to boot up but none of them work. Nothing ever somes on the screen so it's like the onboard graphics just won't work with 6 cards in there.

 I have z270a win10 with 8gpu EUFI mode, rember also not use last driver with signature check or if you try to patch them then window not will start cause it is in EUFI mode, in legacy mode they will start but you can't run with more 7 gpu. i use also gen 3 but i don't see different between 1/3

I appreciate the answer. It helped a lot. Thank you

Do you have above 4gb decoding enabled and have win10 installed in eufi mode? also try pcie lane timing thing from 32 to 64 and peg0/peg1 to gen1 or auto.. I have 7gpu working on my msi z170a pro gaming carbon

Hey guys, I really like this thread and the general vibe. Some awesome projects and I've learned a lot in the last half an hour.

I'm from the UK am currently building my first proper AMD rig, and I bought a Gigabyte Z170 Gaming K3.

Have managed to get 5 GPUs running by updating the BIOS, but the 6th one is proving difficult. I want to know if it's possible or not as a lot of people are saying that chipset is junk and can't handle more than 4 or 5 cards simultaneously.

I have been reading around trying to understand PCI-E lanes... my mobo has 20 apparently and my CPU supports 16. Is that 20 the hard limit (5x4 lanes) or can I run 6 cards somehow? I've heard that if I set PCI version to 1 in the BIOS that might work, as it forces all lanes to use PCIE1x. Is this true or can anyone offer any advice please?

I need to get this one working, or buy a different board before I build my next machine. Planning a tiny (3-4 rig) farm initially

Thanks, and happy mining.

First, welcome to mining. This is a great community where everyone helps.

Your questions suggest you're quite new and still have a lot to learn. I doubt the OP has time to respond, so I'll give you some brief answers but also suggest you continue reading other threads and searching keywords on Google to keep learning about these topics.

1. As far as I understand risers helps us to connect more gpu to the mb, am I right? That's why you guys use?
Yes. Most motherboards used for mining have 6~7 PCI-E slots. If you want to use all slots you absolutely need to use risers to connect the GPUs. Powered risers are the standard these days. Google "usb powered pci-e risers" and you will find lots of information on risers.

2. What about PICO? What is that and why should we use it?
A PICO is a device that allows you to use a server PSU with a regular ATX motherboard. Server PSUs don't usually come with the 24 pin ATX power plug required to power motherboards. So a PICO will get power from a 4 and/or 6 pin cable from the server PSU and plug into the 24 pin motherboard connector.

3. Why do we use pci-e cables, what for?
PCI-E power cables are used to power GPUs from the PSU.

4. How non-reference or reference cards effects mining hashrate? Which one should we choose it and why?
Mining hashrate doesn't vary with the reference/non-reference design. When a new generation of GPUs is released, reference cards are released first. These cards all carry a cooler that was designed by the GPU manufacturer (AMD, Nvidia etc). OEM have their proprietary GPU cooler designs, also known as non-reference. Reference coolers tend to be blower type, i.e. they blow hot air out one direction. Non-ref coolers tend to have better cooling performance.

5. What is breakout boards for?
Server PSUs, unlike ATX PSUs, don't have the usual power connectors required to power motherboards and GPUs. Breakout board plug into the server PSU and "break out" the power into multiple 6 pin PCI-E output connectors. Look for the threads about breakout boards on this forum to learn more.

6. I'm keep seeing "I'm Pulling X watt from the wall" What is the wall reference is here?
The wall is the wall! The electric socket in the wall. Miners usually use a watt measuring device or wattmeter, like Kill-A-Watt, to measure how much power their mining rig is pulling from the wall. Google "Kill-A-Watt" to learn more.

7. What is the difference between ATX PSU and Server PSU?
ATX PSUs come with various connectors and cables to build an ATX computer and power various components. Servers PSUs don't. Also, server PSUs tend to have higher reliability over long term, because they're designed to power servers that run 24/7/365. Server PSUs are also generally rated Platinum or higher in terms of efficiency, and can be purchased second-hand or refurbished for much cheaper than ATX PSUs.

8. Why PSU efficeny is important?
Because the more efficient the PSU is, the less power you lose when converting electricity from your wall to the 12v power your GPUs need. Google "PSU efficiency" to learn more about it.

Simply incredible mining operation, very cool and I'll have some questions for you over the next month

very good results with the mod )
how do you mod these 580, with polaris bios editor?
[/quote]

what the brand of 580? what mem clock at 30mh? memory brand?

not so good is all i can tell..

ahhhh mr. AMD just released a new driver ?

me was on da press version of driver, rx 5xx will NOT work on older drivers sadly

installing new driver & let's see. some results :

so far 2 diff brands of rx 570 4gb comes with ELPIDA memory

without a proper driver, gpu will not be detected properly

stock is just like a regular rx 4xx series BUT with cm's v9 the dcr settings needs to be higher hence higher dual mining results

power wise, SMOS is roughly 20 Watts more than win10 & on win10, more hashpower can be squeezed out n saving a little more power.

brand "S" is a little faster but a little more "jumpy" than brand "GB" but brand "GB" is more stable

SMOS off the wall is about 208W & Win10 is around 182W this is based on brand "GB"

ah an very interesting discovery too brand S wont be able to fully use WattTool, no mem control, no offset but for brand GB everything works just like rx 4xx *correction NO mem control*

avg speeds are roughly 25.5-26.5 mhs on ETH, DCR is around between 790& 800 for both

580 8gb to come

btw, both are modded bios, just basic mod. new drivers have bios signature check !

as for now, stick to win10 & deal with the lower hash from the rx 5xx series, i'm sure there will be lots of improvements coming soon.

pix to come soon. back on the bench for the 580 8gb.

those who are curious, they all look the same as the rx 4xx with minor differences.

FINALLY, something decent ! just small changes, not much done yet but i'm sure more to come soon. time for the capt to go bed. been a long day.



off the wall



STOCK



ENJOY & happy mining to all

Eager to see the numbers

interesting day . . . but SUPER busy. more to come soon. hopefully.

 



tbh, not so much fun yet with this series but i'm sure more will come.

Somebody had made some experiment with mineral oil only for gpus?

Hey Guys,

I read all the comments part 1 thread and I'm currently at the 15.page of part 2.  I couldn't wait more to ask a few questions;

1. As far as I understand risers helps us to connect more gpu to the mb, am I right? That's why you guys use?
2. What about PICO? What is that and why should we use it?
3. Why do we use pci-e cables, what for?
4. How non-reference or reference cards effects mining hashrate? Which one should we choose it and why?
5. What is breakout boards for?
6. I'm keep seeing "I'm Pulling X watt from the wall" What is the wall reference is here?
7. What is the difference between ATX PSU and Server PSU?
8. Why PSU efficeny is important?

I know these are beginner questions and I know that if I search google little bit I can find what they mean but an answer to these questions from a miner perspective, will help me to understand more easily.

Also, I would like to thank jun, philip, finsky and all the others who made the part 1 and part 2 amazingly useful. I've learned a lot and will keep learning more.

there are about 25  really good threads

read my three threads  started about a year ago.

spend the hour plus to read them all the way through  it will give you a feel for how much change can happen in 12-13 months.

If you can give me the links i'll read all of them with pleasure and will be very thankfull

How about you read through the already existing posts about the topic?

Thank to all you guys for sharing your ideas and experience. I'v readed full topic and amazed with all your works.

I still have one question. I'm new with gpu mining and going to build my first rigs. It would be great if i use your experience and don't waste money&time for researching and experimenting. Right now i'm interested wich card is better to go with. I'm considering between rx470 & rx480 also what is the difference for mining between 4GB and 8 GB versions? Which brand and model is better to use for mining ? Which one is more reliable and user friendly in maintance, upgrading, etc...

Let's discuss cards and get finall solution for me and for other interested beginners...
