Topic: VEGA 64 mining FREE WISDOM - page 12. (Read 10803 times)

well, well, haven't we come full circle
this is to all of you whom called me stupid, dumb and even criminal, i have rather enjoyed the ETH price hike from $350 when i started mining to the current $1.150 as it allowed me to completely pay off the rig costs in 50days and are now mining on pure profit
with cryptonight coin prices plummeting, ETH/ETC are just as if not more profitable
was an avid ETN miner until I got fed up with their shitty wallet and non existent service, did the sumo for while and now back to ETH as it shows more promise than any other crypto currency as I had originaly thought

got the 12 x 64Vegas on ETH 44+MH/s stable but I'm having problems with the FE's as i cant get them to hash above 42MH/s
any suggestions are very welcome

Agree. It has to be the pci-e risers. Sata connection is ok though.

I bought some Rosewill riser from newegg.  Very stable.

check your pci risers, i bet my balls you connected them with sata or some of them are faulty

I've been hearing a lot of miners have stability problems mining cryptonight including my bro, hes switching to [email protected]/s as the profitability is nearing on the cryptonight coins and is the undisputed king of GPU mining (I detest asic mining as its been infiltrated sodomised and CONTROLLED, thus loosing the status of decentralised people power, include ripple in that)

I have no stability issues as my miners run days on end without restarts or any attention and before you ask me how read this thread as I have outlined in painful detail the steps I have taken so far

today I abandoned ETN, troubles with their wallet have gotten the better of my patience as after over a month waiting for an answer from their support team has gone unanswered which is unacceptable for a 3/4 billion usd company

they are muppets and their coin is a gimmick as phone mining at max 100h/s yields pennies whilst killing phone resources

i suggest you look into hashvault.pro as they offer pool mining  with very low payment thresholds, difficulty variance ports and an almost realtime dashboard (hover/click mouse over miner hashrate for forced update)
they offer ALL the cryptonight coins for mining including the very new ones, im using them for SUMOKOIN and are pleased with the service

to add, having realised that the vast majority of miners are very electricity usage to hash power oriented (which is not applicable to me) i am working on a thermal to elecrical feedback loop thus converting some of the lost energy (as heat) back to electricity and feeding back to the miner. This project is work in progress as i am designing a closed rig that will be functional for only blower type GPUs like the Vegas, more of that later as im waiting for delivery of the heat exchange device to test efficiency and ths feasibility

Has anyone tested the latest release to see if its improving on the blockchain drivers for overall hashing speed or even just one protocol ?

Right now I find Skunk is the easiest protocol to keep stable and with the lowest wattage, but I know most people go with cryptonight of course.

download and have ready jan4 adrenalin driver and unpacked aug24 blockchain and know the path to it usualy its:

ddu drivers
instal jan4 adrenalin with no card connected
switch off instal FE switch on...wait...wait...wait...
goto device manager make sure its recognised and functioning
disable enable wait as long as it takes, enabled will prob have a triangle
no matter, update driver by have disk browse the path to unpacked blockchain driver
when update complete
disable enable again -it should work *NO RESTART*- happy mining

if not working there is more, especialy for more than 1 FE
will update later,
im trying to get them mining 4 threads each

added one more

had to do some voodoodrivercooking and disable/uninstall device/restarts before they both disabled enabled

cant really explain, will have t wait a bit for a write up but both are running for a total of

2xVega Frontier  4100H/s

if these are your prerequisites for mining then the vega is not your best option, I personally go for top speed and dont care about elec cost as its negligible

that's why I just rigged a VEGA FRONTIER

running on 2050H/s easy

what a pain to get it started though, I will get into later but a lot of driver cooking was involved
5 Frontiers to go......

Is there a way to lower voltage to less than 860mv for GPU? I can't make my Vega 64 to slow down, it will mine ETH 37MH/s minimum and 42 MH/s when tuned.

But there is no way to lower hashrate and decrease power draw. -50% power does nothing, 850MHz(minumum) on core does nothing - it will not mine slower than 37MH/s. This is the first time I see something like this on a GPU. I mean I don't mind because the power draw is low but seriously.. What if I want to go lower than 150W power draw? It will not crash, it will not lower voltage, it just goes fast and doesn't listen to me.

Why on earth anybody even produces those blower cards if they can`t handle the work 

So I have a MSI Vega 56 air boost and a XFX Vega 64 reference model.
the 56 is rock solid at 42MH/s without breaking a sweat but man this 64 can't cool itself down. it starts off at around 41MH/s and throttles down to 37MH/s.
i've been using 1100MHz, -30 freq, 3000-3700 fan, -13 power limit on the blockchain driver. 56 is 950MHz, -30 freq, 3000-3600 fan, -15 power limit and its outperforming the 64 in every possible way.

I'm updating my drivers and trying out your wattman settings, will report back.

i noticed with Cast XMR (CRYPTONIGHT) that one of the cards in each rig heats up significantly more than the rest
found its the number 1 in the NTool dropdown select
dont know why dont ask, i just set the fan speed higher on that one up to compensate

----------------------------------------------------

AND MY FRIENDS

for all the shit i had to put up with in the beggining of this thread im BACK ON ETH hahahhahahahahah

with the same setup as stated in the beggining of this thread running the dirty dozen at 528MH/s 2610W stable

ps
getting a new toy soon

If you want to run 6 x 64's then you are going to need a decent ssd drive as you'll need to set at least 60gb as virtual memory if you want to get them all running on a single rig without the miner constantly freezing and crashing every 20 mins to a few hours.

dust and fluff is not only fire hazard but build up of it inside the airways and circuit board of the Vega can cause bridging between curcuit components and fry the card and/or block the heat sink thus causing overheating and again diminish performance and/or fry the card

the front panel of the Vega is easy enough to remove (6 screws) providing easier air flow thus better cooling

but again the key to keeping your cards cool is AMBIENT temp and not fan speed as running 40C ambient air through the heat sink at 2000rpm has almost the same effect as 4000rpm

yeap, i live in beatiful Norway where electricity is produced via hydroelectric dams at an average retail consumer cost of USD0.04kWh and the outside temp right now (winter) is -10C here just outside Oslo.


dont feel so bad the oil money is placed in a fund that is used ONLY to support the global ponzi dollar scam and not invested in the country itself managed by a special EU body of non norwegian non elected nobody yesmen

I think he said Norway. I'm a bit jealous. Not just for cheap power, but they did a lot better job managing their resources there than where I live.

(I live in Alberta)
My Vega's are stable at about 1950 H/s each on cryptonight using cast xmr and stock bios, basically set up as per http://vega.miningguides.com/
I'm not sure what else to throw in that rig -- maybe will just hold out for when the custom vega cards actually show up to purchase in Canada.

Another fire hazard is dust, dont let any dust build up near to a bunch of hot cards or it will possibly provide fuel for some damage to occur.   Get out the hoover if need be.    I dont know about interference especially but some kind of cheap faraday cage around the setup might be an easy solution. 

I missed where is the electricity this cheap, you pay bulk rates I take it ?   solar or hydro power would be ideal but theres setup costs to it

The thing is, it sits alongside 4 other rigs that are 100% problem free. And I observed this problem in different rooms of the house (I build them in office then move to garage).

But I will try to swap out the PSU, etc, and test that...

i did mention this in the earlier pages,
had the exact same problem and the mobo would recognise different GPUs each time, seldom all of them

im willing to bet this is because you have Electro Magnetic interference from a nearby source/device, a bad contact that is creating a spark in the wall socket or elsewhere for example (which is also a fire hazard), or a faulty screen or a strong transformer  anything that you can imagine that might be creating a strong enough EM field and is close enough to affect mobo and/or GPUs, heck it could be the smart meter on the other side of the wall, or your neighbour plays with stun guns or a cell antenna array pointing at your location i dunno but it sounds identical to my debacle

are you using a wifi adapter? that might be the cause also

try moving the rig (if possible) to another locale, change contacts/wiring/psu/ remove anything electric and electronic from the rig vicinity

electronics (especially precision ones like what we build)  are very sensitive to EM, keep this in mind when placing your rig

in my case it was an Ozone generator (which uses a spark gap) more than a meter away

good luck

i managed 2260H/s on Cryptonight with 200W but it was not stable past the hour
also stable 44.5MH/s on ETH 210W (which is looking attractive again at almost $1000ETH)

havent tried anything else as ETN has been working well for me so far (mined a little SUMO too)

i really feel for all you guys having elec cost in mind when mining,
i dont as its stupid cheap here 2640W 24/7 costs no more than $45/month for a return of around $3000/month
everything else is horribly expensive save electricity ($0.04kWh) and electronics

more info would narrow the possibilities
could be:
cast xmr dowloaded file is corrupted
a riser and or cabling is not working well
forgot to set virtual memory
using conflicting PCIE ports
your cast run.bat file has a typo
one of the GPUs used is not AMD
try running Cast as Admininstrator
check windows is not blocking it (Defender)
none of the above
