Topic: My second ZEC + XMR+ ETH thread builds info links thoughts and photos. - page 83. (Read 147923 times)

Well, I continue to try and tweak my clock speed and voltage settings on my 4 RX 470 rig.  At last check, I had finally got all 4 cards up slightly from 20.75 to 21.45 Mh/s by setting clock speed to 1700 (max amount in my Wattman for some reason...Afterburner allows all the way up to 2100 so not sure why the disconnect).  Unfortunately, this increased my wattage at the wall to ~730-740 (from ~625 before the tweak). Obviously, this was a net negative trade-off, so I went back in and tweaked some things a bit earlier today.

First thing I did was reset everything on all 4 cards. I wanted to get back my power savings first and then start to mess with clock speeds.  Looking only at the GPU mV by state, I first took a crack at lowering state 4-7 of my 2 hungrier cards. For what ever reason, these 2 suck like 15% more power across the board than the other 2, so I chopped them down a bit. Unfortunately, I must have lowered it too much as 1 of the cards crashed, then my system crashed and rebooted. So, I dialed back the reductions a bit, as well as lowering the other 2 cards. This time all 4 cards were stable and I was actually showing a bit lower total wattage than my original low at about 615.

From here, I upped the clock-speed to 1700 on only 1 GPU to test the result. The HR did go back up to 21.45 and surprisingly, Afterburner was showing almost no increase in wattage pull!  BUT... when I checked my kilawatt, the wattage had jumped up about 50W!  So... 2 questions here:

1:  is a 50W bump for only a measly 1650 to 1700 over-clock reasonable?  I never OC'd before but this seems high for such a nominal increase

2:  why would Afterburner still show the wattage on this card at around 74 both before and after the OC, but my overall wattage pull increased by 50 at the wall?  Does this sound "normal" or is there possible something wrong elsewhere in my system?

I also did some benchmarking on other system resources finally. At boot up with nothing running (except windows of course), I am at 95W (not including monitor that is not plugged into my Kilawatt unit).  Then I launched MinerGate, that I have 7 cores of CPU mining XMR.  This added about 45W. That CPU is hashing about 260 on XMR so that's a semi-decent side-profit of about $10/month lol.  

open amd wattman

reset every card to stock.

then check watts and mh

then open wattman go to bottom  leave gpu alone leave volts alone.

set power to - 20 on all six cards

set fans  at say 2000 - 4000   if they don't go to 4000 set at 2000 - 3000

set gpu temp to 72 - 70    you can do 68-66


only that bottom section gets set.

let us know mh and watts    watts for 140mh should be 950- 1000-1050

question is.. what would you like to do?

UPD. 1 - I tried. This card hash dropped from 24.8 to 4.22MHs. And is not going back - have to restart

UPD. 2 I've undervolted all of them by -50mV and now getting 1130W

UPD. 3 Tried to increase mem clock from 2000 to 2100MHz - system crashed

Do you at least turn down the power by 15 to 25℅? That should help.  What is your power as reported by GPUz per card?

To community:

It looks like my rig is super unoptimized

I have

3x RX 480 Sapphire Nitro+ 8GB
2x XFX RX 480 8Gb references
1x MSI RX 480 8Gb

My total hash rate is ~148MHs (ETH only, CDM)
Wattage from the wall: 1200W

All stock values no OC, flashing etc. Win 10, last drivers

Any ideas?

So with 150 mh, I should get 6 more cards to mine at ETHPool ...

LOL !!!  

Thanks to all of you, my rig has been up for 18 hours, rock solid.

EDIT: Anyone tried to get a replaced with a card with a "bad ASIC" ? 69.1% Anyone has a lower ASIC then that ?
EDIT2: I'm 4 days away from my first block
EDIT3: 150.0 MH/s | 164.0 MH/s | 140.0 MH/s (Getting there !)

Thank you for the information so far.  

I would also like to know where to hash between Ethermine or ETHPool?  Has anyone evaluated this with numbers?

1) Which pays out most profitable?  
    -Ethermine pays out Minimum: 0.1-10 Ether;  ETHPool pays out at 5 ETH.

2) Has anyone seen Uncles on Ethermine?
    -Both pay all Ethereum rewards (Blocks, Uncles & Fees).  I do see that many have seen profitability of Uncles with ETHPool.  
    -Ethermine advertised 0% fee although I see 1% on their home page; ETHPool is 1%

I am at 300Mhs.  Any recommendations?  

Another Question: What Wallet do you use?  I currently use Jaxx that has BTC, ETH, DSH and DAO.  It can change ETH to BTC inside the wallet for 2%.  Does someone have a better option?



By the way, Thank You Phil for getting into this and providing this information.  I have valued your posts all over the forums!

yeah I would switch to ethpool if I were you.

650 will earn the full block fast enough.

Guys, I asked few month ago where to mine with 160mh/s and I went after disscussing with you to ethermine.

Nowadays, I manage 650mh/s, and everything is still at ethermine.
Would you advice to change ?

Ethpool is like PPLNS pool - this is my primary pool using Claymore Dual Miner.

My 3.8GHs farm mines up to 3 blocks per day. Used to be up to 4 blocks but with crazy diff levels it's hard keep up.

If you have more than a few hundred MHs, ethpool will be more worthwhile.

It takes longer to get the full block reward due to higher difficulty now but nevertheless, if you have big hash, ethpool is ideal.

ethermine pool is also created by the same guys at ethpool.

If you like PPS like pool, then this is a good one.

Simple and consistent both pools. Nice stats and Android app support. Just plug in your ETH address and off you go.

Pool op (Dr_Pra) is also active at ethereum forum.

Ethpool is great if you have good (doesn't need to be great or amazing) amount of hashing power.
Uncle payments and big blocks are what you are looking for on ethpool. You will get one it's just a matter of time

Ethpool pays uncles.  They pay a full block so you need a while to earn the block.

My 450 mh takes three days to earn a block.

But when I get an uncle or a megablock I get as much as 9 coins vs 5 coins.

I have had seven extra payouts maybe 25 coins since April

It's really great except that it reset the settings upon any crash I have.

If I could save/load profiles, it'll would be a nice workaround.

Does anyone have a preference to Ethminer or Ethpool? Why?  What is the difference?

just by strapping them together (pcie riser usb cables) with a zip tie or wire strap(of any material) can give a bit of sturdiness to each connection. never had a problem with them getting loose, to add that these are old boards.

back to 20 cards  I got the asus to do 3 slotted and 1 with a riser.

It can be very counter-intuitive, at times.  I've seen where I increase the memory frequency and my hash rate goes down, because the gpu clock goes up to where it wants to be (to maximize the power budget) and the overall power budget gets dominated by the gpu instead of the memory.

Voltage is the biggest lever we have to play with, because power is reduced by the square of voltage, and is only affected linearly by frequency.  Therefore,  voltage is more fragile of a factor.   (1/2 * Capacitance * Voltage^2 * frequency = power).

Couple the above equation by the voltage of the gpu and the memory, and it can get very tricky to get the card to do exactly what you expect it to do.

Thanks Lone... I just had what at least feels like a breakthrough... or at least did for a brief moment lol!  I did a reboot after setting all cards to 1700 in Wattman and 1851 in Afterburner. Still no movement at all on HR.  Then I noticed I was back up to ~690 watts vs the ~625 from before the reboot.  After looking at Wattman, I realized that the State 6 & 7 lowerings I made yesterday were reset. So, I changed them back to roughly what saved me the 75 watts. At this time, I also move the memory back up to 1700 as that was reset too. In addition, this time I moved the GPU frequency slider bar to -10% on all 4 cards.  Started up Claymore again and was happy to see that all 4 GPU's were now up in HR, albeit slightly (from 20.75 to 21.45). But unfortunately, I then checked my wattage and it had ballooned up to 770!  So, I obviously need to do some more tinkering because I am pretty sure that a gain of 3 Mh/s is not worth an extra 140 watts lol. But, at least good to know something has finally affected the HR. Is it possible that the GPU Frequency set to -10% increased my HR? Seems counter-intuitive but I am still learning this stuff and that was the only new change that I made.
