bump

Price drop. Ready to ship immediately.

For the new Nitro Vega56, thinking $850.

Used Vega64 and Vega56s (they mine the same), $800ea.

I only used them for a few days until I got transferred - been sitting off collecting dust ever since.

I have a few GPU mining rigs and have a couple of spare Vega 56s.

Sapphire Vega 56 NITRO+ 8GB

This one is NEW, and never mined on.

If anyone is interested, I'll travel to take pics of it as proof and will make another thread.  I also have the original box and accessories.

I also have some Vega 64s and MSI Air Boost Vega 56s that are mining.  I'd rather keep them, but if someone is truly interested in the, I'll take some photos for proof as well - and will post another link.


Basically, I'm sending out feelers.  It's not worth the 8 hour round trip to where I am hosting/storing them for pics of proof if no one is interested.

Brand new in box, never used.  Full 90 day warranty (that started today upon delivery).

I also have the matching 1300W PSUs for each unit and they are included.

$2000 BTC each. firm.  $3800 BTC for both, firm.  Other crypto welcome as well (e.g. XMR, ETH).

I also have 220V 1400W matching PSUs, new and unused.  Additional $100 each.

Free 2-Day UPS Shipping same business day if paid before 3 PM EST.  Shipping to US and Canada only, with REQUIRED ADULT SIGNATURE (well, Canada may need another day or two for me to figure out the customs labels).  Located in New York currently, near NYC so can meet up for even faster service.

Video of boxing-to-ship-and-ups-scan-with-address will be taken to avoid scammers.

Escrow is an option, but buyer pays and will only accept escrow from known agents/brokers here on Bitcointalk.  Aka "The Big 3": Monbux, Tomatocage and OgNasty.  However, as you can see I do have Trust and here's my Heatware for more: http://www.heatware.com/u/80239/to  So you don't really need escrow: I will deliver (as long as UPS delivers reliably to your door).  As usually, if UPS loses the package in transit, I will issue a full refund and will file a claim with UPS - just like it should be.  However, if UPS delivers and it was signed for, my transaction is complete and it's up to your local police department to file a theft report for stolen goods.


You'll also need an Avalon Controller.  They can be had for like $130 new.  However, it's just a Raspberry Pi with an image you can download and flash to a card.  I can do this for you FOR FREE and include it in the box, as I have a few extra Raspberry Pi boards.  But it will delay shipment a couple of days as I flash and verify the controller.  You'd make more money if you just buy the unit and I ship immediately, and while you wait you can get an Raspberry Pi and flash the image yourself so when it arrives, plug in and go!

Will do later in the day.  Need to get some work done. 


So something happened between the multiple reboots and power offs this morning.  Seriously, only setting that changed was me enabling/disabling HBCC (all GPUs are Enabled at the moment).

Now I get has rates at 1900/2000+ with the correct memory!


...Except, 1 GPU.  When I "Disable/Enable" it in Device Manager, it no longer comes back and always errors with a Code 43.

I've tried moving it to another slot, swapping out cables, pcie risers, etc.  Doesn't matter, same GPU always fails to be "re-enabled."

But the other four are happy now.


Close...

Let's examine everything I am doing...  Let's take a look at the mining settings.


Testing it on the true Vega64 first to dial it in, before I start tackling the Vega56s.

I've tried this pool, and a few other coins. 

I've tried with and without --fastjobswitch.


That port, 7777, is for "highend hardware" starting at 25,000 difficulty. 

I have tried lower difficulty, of 5,000.  I have tried setting the difficulty flat in 50,000 increments from 50,000 to 350,000 to no effect.

I don't have any options to enable/disable crossfire.  That area is blank in my Radeon settings.

I didn't before, but now I am Disabling/Enabling each card after a reboot just in case.  It has not helped.

I also have tried the trick of enabling/disabling HBCC memory segment - and it doesn't have any effect either on hashrates.

Only tweaking the memory to 1050 or 1100 increases it to 1200 or 1300 depending on the card.  And lowering the GPU voltage to 900mV greatly reduces power consumption without affecting the the hashrate at all.  If I leave the GPU vcore at stock voltage, the hashrates are the same. 

I installed Windows without network connected, disabled Windows Update and that little known driver update portion as well - before I connected to the internet.

Remember, I am using the IGPU from the Intel CPU connected to my display, so I didn't need any drivers to use the machine upon setup.

Then I connected the internet and went online to download the blockchain drivers. 

But yeah, I guess somehow Windows snuck in a driver even with everything disabled.


I used to open MSI Afterburner just to keep tabs on the cards as I am most fimilar with that app over the last 10 years with its logging and INI settings.

However, I no longer load it - and just try to start mining.

Again, it doesn't make a difference.


I'm missing something there...  I'm sure it's something easy.

Well, the good news is after a full pave and reinstall of the drivers - I no longer get that warning message of not using the blockchain drivers.

I am also now able to use the same tweaked settings in the guides, and getting around 1300 H/s.  So yes, that's a little better.

But still a far cry from 1900 or 2000 H/s as advertised.

Guess I'll sleep on it.  Let me know if y'all have another ideas.

Yep, that's the exact driver I installed. The installer shows 17.30.1029 however the info page shows 17.30.1091.

At this point, I've just paved the entire PC and I am installing again.

I saw that disable/reenable in a few guides. But the newer ones don't have that step.  I'll try it now though; however, I do reboot often and power-cycle without any differences.

Back... Nope, made no difference at all.  Even powered off, booted, disable/enabled in device manager.

Oh and not 900mhz core - 900 millivolt.    It greatly lowers power consumption.  Even at the full stock millivolts, it makes no difference in mining.

What bugs me is that it continues to say:

 "[22:35:41] Blockchain Compute Driver NOT detected."

The AMD installer explicitly says 17.30.1029.  However, once installed it shows 17.30.1091.  Yes, I ran DDU as well to clean.  Still only 1091 gets installed?


EDIT: If it matters, I do have IGPU enabled in bios and am using the onboard video.

Hello all.

I must be missing something simple as I am not getting the expected 1800-2000 H/s per Vega out of my setup using Cast XMR.

AMD Blockchain drivers Aug 23rd, 17.30.1029 as the Installer says.  However, the digging into the Software stuff shows "17.30.1091.1011-170922a-318486C"

^- note that this is dated Aug 23rd, where others are saying "17.30.1029".  

Also Cast XMR says that the Blockchain driver isn't detected!?!?

I only get the following:

Vega 64: ~1250 H/s @ 1630c/900mV, 1095m/1050mV (stock settings is ~930 H/s)
Vega 56: ~1150 H/s @ 1630c/900mV, 1095m/1050mV (stock settings is ~870 H/s)

I started off following this guide to the letter: https://steemit.com/mining/@briggsy/briggsy-s-exhaustive-vega-56-64-monero-mining-guide-part-1-flashing-vega-56-with-vega-64-bios

I've since moved onto about a dozen different guides and recommendations.  Been browsing this post for hours and trying all sorts of combinations.  Nada.

One thing I have noticed is that Cast XMR does not report the proper temp or fan speed for the given CPU.  At least, I see a vast difference between Afterburner and what Cast XMR says (not the different GPU numbers, but actual values).

1x Vega 64
1x Vega 56 (flashed to Vega 64)
2x Vega 56 MSI Air Boost OC (can' flash to Vega 64)
1x Vega 56 Sapphire Nitro paperweight

Windows 10 Creative Update fresh install.  I have disabled everything with the "Windows 10 Registry tweaks for mining.bat" batch file (saved me the trouble).

I'm trying to stick only to OverdriveNTool for tweaking the settings.  

I've over-volted and under-volted.
I've +50% Power Target and -30% Power Target.
I've overclocked core and mem (oops, crash).
I've tried various combinations of all of the above, and left some alone, and can never see more than 1250 on the Vega64.

I've tried one GPU at a time, all GPUs, various combinations, etc.

I have not done any registry edits, as it seems the more recent guides don't have those settings.

I have tried 5 different pools and 2 different coins - all with the same effect.

Any help would greatly be appreciated.  

I got one.  Jesus... This is a clusterf***.

Get one in your cart.. And go to Cart page.

Keep refreshing and hit Checkout.  Keep refreshing and hit Checkout.  Keep refreshing and hit Checkout.

Once you get to the PAYMENT page, you're golden.

I simply want to trade BCH and BTC.  No cash out.  No banking funds.  Just simple buy/sell.  Transfer in, transfer out. That's all.

BTG is a bonus if supported.

What are some exchanges that do not have, or require, KYC and AML for these simple transactions? 

I looked at BITSQUARE (bisq.network) and doesn't support BCH.  Bummer.  Even though its low volume, the prices aren't that far off and there are active trades going on right now.

Value isn't a lot, like maybe $10-$30k over time.  But it's nothing the country of origin should care about with KYC or AML.

The RPi Zero 1.3, "non Wireless" is only $5 in the US - and this looks like the one you have for sale.

The Wireless edition is $10.

And shipping from Venezuela to US?  Yowsers.

Does anyone have any broken miners/PCBs in need repaired?  

I got to thinking, I have my own reflow station and fully stocked workbench where I repair SMC PCBs all the time for various projects.  And I've been reading about a lot of failing boards lately.  So, why not put this stuff to use.

I've been searching and dug up some details for the Bitminer/Antminer line of products (S7, S9, etc).  Others I am not so sure.  We will research together before starting any project to maximize success.

I am located in the US.

PM me for details.

Offer pending on eulogy.org...  Will take additional bids for the next 48 hours.

Video!  Oh please, videos of this! 

Always in aww of Eve Online as I have no time to play.

Ps, not interested in buying.  But a free bump for a sweet game!

Maybe i should tone it down to a basic website I'll do for ya? 

So, I have some time between gigs ATM.

^- should speak for themselves.

Specializing in distributed systems on AWS and Windows Azure (currently tinkering with Google Cloud).

I also have contacts of designers and marketers if needed.

Am not looking for fly-by-night jury-rigged systems.  I'd just come in and want to rewrite everything if so.  Unless, that is what you are looking for - someone to rewrite something to handle high load and scale, securely.

Recently helped a DDoS against a Onion bitcoin mixer site which was down the majority of the time.  After a few hours, we were back up - while the DDoS continued for days - and even grew larger.  A few days later, the site is performing flawlessly even though the DDoS continues.

Contact me via PM (slow) or through my site above (faster).

Based out of NYC, we can meet in person if you like.

Small gigs, prefer BTC as payment.  Longer time commitments we can negotiate.
