MY buddy has a power supply kit selling right now for a reasonable price; so I thought Id share with you guys:

The kit has a 2250W 12V capability;  and are ~$155 shipped.

They are in the form of 3x server modular PSU with breakout boards and 6 pin PCIE pigtails.... He has them arranged for use in antminers, avalons, etc....

https://www.ebay.com/itm/282378575981

LMK what you guys think  about the price and product....   Ive seen his stock;  he bought cases of the PSUs (they all look brand new), the PCIE cables are brand new (not cheap flimsy ones), and the breakout board is professionally made (in china).

Presently hes having them make breakouts for the other 1600w+ PSU's he has been looking into sourcing for similar kits.

I have also given him the heads up about GPU miners on how they need to have 8 pin plugs, and he should consider adding support for the 8 pin plugs, not just 6 pin.

Im not sure what his margins are on these power supplies, but maybe I can do bulk discounts for you or something.... need to check with him if there's interest from one of you guys.

Hey everyone... happy Black Friday!

Was wondering if someone could provide some insight that is currently (or recently) mining ETH with RX 400 series GPUs.  I had my 4 6x 470 rigs mostly on cryptonote for the last few months but am now looking to switch back to ETH+DCR.  However, I am still on the 16.10 drivers and know that with those I will only get about 75% of max capacity, so need to update my drivers and possibly other apps.

As far as drivers go, I know AMD published Blockchain drivers that apparently fixed the reduced hashrates but caused other issues with power management etc.  I think these are here:

http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Blockchain-Compute-Release-Notes.aspx

but this says beta version not to be updated. so, is the best driver to use for 470s currently? or is there a better one out there?

Also, I believe that I am at least 1 version behind on Afterburner. I've read that the newer drivers also require newer AB, so if someone could also elaborate on that it would be appreciated.

Finally, is there anything else that I need to be aware of when updating to a more current driver?  For instance, will watt-tool still work? I use that for my master under-volting settings and manage over-clocking in AB.  Can this still be achieved with the newer drivers?

I have had an abundance of PM's all the sudden on me mentioning Gunbot, instead of responding to them ill just post my review...

I honestly dont recommend buying it unless your planning on using it for auto-selling function and even then its pretty pricey to purchase, so larger setups i would only recommend it for...

It works well as a bot on slowly gaining you a profit, but in a few months of using it i have done nothing but brake even, because there are to many groups out there that coordinate pump and dumps, which the bot is unable to detect and gets caught in a poor position due to one of these pump and dumps, so over a 3 month period every bit of profit the bot would gain me over time was wiped out by multiple pump and dumps on multiple coins over time. The only way i use it to trade now is on the top 5 currencies, due to how little pump and dumps effect those coins, but in my time of using it on those coins only its only making trades 1-5 times a month for the 2.5% (3%-.50%) profit, but it trades so little, that the cost of running it is just not worth it at that point, because it highly task your CPU, increasing the wattage of your computer your running it on, so i now use it for this and auto-selling with one of its features it was not really designed to be used for.

Overall i am still slightly recouping the losses i had from the pump and dumps, but im basically about even now and plan to mainly use it for a auto-selling script basically.

i add custom pools, most of my coins i mine on Suprnova... i find for some reason i net more coins mining directly from them vs other pools directly mining. I tried a few others like hashrefinery and Yiimp, but in the end i was netting more from Suprnova. The only downside to Suprnova is the website lacking, many times i cant access it to view anything or its down, but the suprnova app seems to always work. Also what i do is send every block if its a slower block speed or every few if its one of the 1-2 minute blocks, i found even tho i pay more in transfer fees sending it out pretty much every block, but i found i was able to catch higher exchange profits on bittrex or cryptopia over waiting every 30 minutes and sending out.

I use Bittrex's auto conversion feature for all coins on that exchange, the ones that are not on bittrex that i mine are usually on Cryptopia, which i use my Gunbot to sell with. instead of the bot trading on those pairs that i mine on for Cryptopia, i have those coins flagged in emergency sell mode, so as soon as the bot detects a balance on those coins on Cryptopia, it sells within seconds of being verified on that exchange, which has turned out to be a nice upside to this failed bot of mine i own.

for the onda b250, what are the front panel connector colors for power and reset? i could just start shorting them and find out but figured i would ask.

plan on messing with it this weekend as the ram (last thing i need to boot) comes saturday. building a frame today.

It's just a shoplot unit, 3rd floor. Basically the building's staircase is locked with a gate, only tenants with key can enter. Outside my unit there's more grills and doors.

I feel safe because it's a shoplot with this many deterrence layers. Also have CCTV. If I rent a warehouse, it's pretty easy for people to climb over a fence. Definitely gotta think about that as I'm renting a larger place next month.

For parts, I buy on Amazon. 1080tis are $850USD in Malaysia. Many pc parts are 20-25% price premium. Back in June I paid $659 USD + $69 shipping/import fees to buy from Amazon per 1080ti. I also max out my 37kg luggage with GPUs/mobos and stuff whenever I fly there. Amazon increased their prices to $750 now (+$80 shipping), so I might consider buying in Malaysia, but crappy 1080ti models in my home country are still $680-$700.

You can just walk(fly) in East Malaysia and find a place to rent. Foreigners can rent. Landlord can apply for electricity in his name, later you just pay online when the bill comes.
With your investment, you'd want an industrial unit, RM2-3K per month. Plenty of space for expansion.

As for partnership, for veterans it's much more profit if you self mine.  

I host for a few relatives and charge 30% commission after electricity. They don't know crypto or computers well, but like the ROI numbers. They just ship me equipment. I mine to their exchange account and end of every month money is withdrew from exchange to their bank.

Hey Storx, which pools and coins are you profit switching with awesome miner?

I'd like to try that and compare to sniffdog

How do you handle physical security?  Is this some sort of warehouse district?
Do you buy your parts locally? Can you share pics please?

I live in Australia, Malaysia is close (relatively). Do you have to be a dual citizen to rent a building and set up electricity accounts?

What could I get set up with 50-70k USD? Enough to be worth it?

Sorry to ask but I kind of want to expand in this way. Do you consider partnerships? 😉

Malaysia. 5 cents electricity, 1600sqft for $250usd monthly rent.

Well I ended up buying a 1200W PSU and 4*Vega56 for a rig and another 1080ti to complete my other rig.
So now I have;

7*1080ti
1*1070
4*Vega56

I sold 15% of my POWR and 25% of my ZEN to fully fund it all.

I'm still itching a lot and want to sell more POWR/ZEN to build a 8*1070ti rig. I think that would satisfy me for a few weeks. It comes down to whether I want to sell or keep these currencies.

agreed.

And, the other aspect people misconstrue about profit/algo switching;

different algos have different power requirements.  Some stress almost every single register/function/transistor in the GPU; and thus take WAAAAAAAY more power than others that have simpler more repetitive functions and are done with the GPU.

People could falsely count this as stress from profit switching;  but this in turn could be related to the before mentioned;  overclock (most times different over/underclock is needed per algo), power supply/condition, etc etc etc.

Just adding one external fan in my rackminer case sucking air from the gpu/OE riser locations.... has drastically improved my temps in this box.   I have a watercooled cpu, and 3 9-series video cards in it.  And let me tell you;  I can and do use it as a space heater no problem.  It has the OE rosewell fans on it (low speed and quiet), and has a similar fan added to the outside I mentioned above.  Its a touch noisy if I turn on the power supply "fan increase" button.... but, I can live with that.    This sucker heats the whole RV I live in on the ranch.... almost too much heat at times, but as they say:

Winter is coming......

*edit*  The only downside, is if the new series of GPU is incompatible with the old waterblocks....  Which kinda feels like a hit, but when its reused, its a godsend.  Either way, I think watercooling is the smartest avenue in the end.  Just keep a res tank outside;  put a radiator on it if you feel the need.   then just have a pumpable loop you can tap into on the inside of the building.   Or separate the water/device zones if doing it all indoors.

I have an old theater coolant tank/pump I saved from when they closed down a theater I worked at.   I figured just mount it outside and have it routed indoors to my machines.


Just gotta spring for the waterblocks and fittings at that point.  Depending on the flow of the primary pump, you could have many different conceptual configurations for a farm, such as a pressure/dump system...

This is exactly my logic, which is also the other factor i want to remove from my reliability issues.. im looking to move over to pure watercooling on all my rigs going forward for mining. I have bought the crimping kit so i can use commercially available PEX tube from local hardware stores along with generic copper barbs in the odd G12 thread, because one i found the soft tubing on my other 2 watercooled mining rigs to give me issues after a while from the sustained heat along with the excess cost of the crimp lock connectors used in most personal pc's. The barbed fittings are a fraction of the cost when purchased in bulk and PEX is much more reliable and rated for the temps much hotter than i could ever see in my rigs. I want to move over to a commercial style pair of pumps with a 2 tank system using gravity flowed cooling like my current rig i have running with PEX tubing for lines for testing. That way i no longer have to fish out a GPU due to fans making noise or stop working. I have had a whole mess of gigabyte 1080ti's have fan failures on me over that past few months, literally the only brand giving me more than an expected amount of failures for mining and it seems the rigs never act the same once you take them apart to access that one single GPU giving you issues.

Its just the amount of power you save over removing hundreds of fans from the GPU's and using a fraction of the amount on radiators along with the extra boost in hashrate you gain when its running on constant lower temps just basically wipes out the cost of a block purchase for that GPU, granted setting up the water loop is an extra cost upfront, but its not an ongoing cost once its all purchased and installed if you ever upgrade the GPU's.

switching software does nothing to mining gear.

What effects mining gear the most, is temperature, dust, and power.  The software; just dictates what its doing and when for the most part.

If you run your gear overclocked and hot;  don't expect it to last as long as stock settings and a proper temp environment.

I killed the fans on my GTX980 recently because I closed up the rackminer case with improper ventilation and it was causing the 980 to have 100% fan speeds for a month.  That was enough to kill one of the fans, and the other is about to go;  my replacements should be in the mail tomorrow....   But had I left them in the position to be running at <80% fan speeds;  the fans would still be good.

See this is the thing i dont understand, how does switching what you mine harder on the equipment? as long as your adjust your settings and difficulty it shouldnt be an issue imo.... heck a video game is more switching on a gpu than a profit switcher, idk maybe im wrong and just not been around long enough to see the long term side effects, ive only been mining almost a year now this stint of getting back into it and have a lot to learn....

I just dont run the cards to the very edge, i did when i was learning on my early gpu mining days with trying to fine tune them to get the absolute most i could out of them, now i push them out tell they are stable while making the most hash/watt within reason i can achieve out of the gear, when something crashes or locks up on me, i scale that rig or card back more not just 1 point, typically 10 points so im not expecting perfection out of the gear with OC settings, i found this to be the root of most of my issues with my gear outside of the pesty freaking risers, granted superglue did make a huge improvement in the reliability, but they are just poorly made and dont last very long between caps singing or popping on me...

I am actually planning to buy property to do mining more on a serious note in the near future in a safer manner... i really like an idea that a guy in panama does with his gpu farm. He bought a section of land and installed a concrete slab with a shipping container that has doors on both ends, then he welded in a homemade server rack setup directly in the middle of the container and installed all of his GPU's equally across all the rack mounted 6U cases, then at the intake side of the shipping container he installed a thick mesh of bars across for safety as well to provide a surface for him to install the filter media, which to filter the air going into the server racks. The exhaust side of the racks is exhausted out to the world via another mesh door system for protection also. Which is probably all the length i would go with it...

The guy actually combined the crypto mining with a new business he started with drying of wood, he recently butted up another shipping container to the end of the first one and directs all the air through another full size 40ft container, which he stacks wood inside of to rapidly dry via the heat from the farming gear. He also installed a small solar system on the setup to offset some of the electricity cost during the day, by adding panels on top of the shipping containers.

I really like the shipping container idea, because for one its mobile, so you can buy property as an investment and have electricity installed on the property with a permit for a non permanent building, basically the same requirements for people who place mobile homes on wooded property, so the cost to do it is very low compared to permitting an installed permanent building. Second it brings down your overhead cost, because your paying less on taxes and cost to get started and maintain the setup on the property. The use of mobile shipping containers is just a great concept which seperates the heat from the gear from being re-circulated back into the gear along with the noise and heat being located away from your home.

May I ask in what country do you mine?

I will never buy a brand new asic ever again unless it does more than one algo, or is brand new tech securely in my hands at expected release time with no funny business like bitmain and other companies have done....


so like the board I bought from phil;  brand new, untested (mostly,), etc....  but known source and right away delivered.

If I had that in an ASIC that had more than a chance of not getting profitability screwed like normal batch1-2 users... then i may consider....   but... I dont trust asic profitability anymore.

I bought my s3/s5/s7, ran them, then sold for what I bought them for... so.... I got lucky.
