L3+ Way Overclocked! 500M frequency - 650 MH/s!

[Rexmint]

I was planning on running my L3+ at 500M for 24 hours but my power went out about 18 hours so Ill run the test again starting now. Just started about 6 mins ago.

Here is what I got so far....

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

I will get a KillAWatt reading later.

Likie I said I did have this running for almost 20 hours before my power went out on me.

If anyone could refer me to a guide so I can firgure out what everything means like "DiffS" and "DiffA" and all the rest I would appreciate it.

I have been earning about $1-1.25 per on NH with these settings. ProHashing was too unstable for me to get a good read out.


Has anyone pushed their L3+ this high or higher before? I figure with the rapidly increasing difficulty and my 90 days about up I dont have much to lose. Would really love to hear what you guys think and have done!

Ive looked HW up a bunch and if its anything like GPU HW then it really shouldnt be an issue has their fixed internally. My first (and prob last) ASIC.

My ASIC is in my garage which is gets pretty cold at night - around 35-45 degrees F and durning the day I would guess maybe 60 but that is with fans running.

Your thoughts. Once this is all done I will make a video!

Sincerely
Rexmint

Tips appericated for my testing would be greatly appreciated...

The L3+ is advertized at 504MH/s stock. i have mine overclocked to 576MH/s. Do you mean 600MH/s?

[Rexmint]

 Sorry I may have not been as specific as needed.

The L3+ comes at stock set at 384M frequency (I think) which equals out to approximately 504 MH/S.

My first overclock I had it going around 600 MH/and I believe that was at 440-460 frequency.

As you can see in my post where I outlined the settings I have overclocked it to 500 frequency which is given me approximately 650 MH/S.

My question is if anyone has set a frequency of 500 or higher and if so if they have seen any issues? The only issue I see currently is the high HW account but at least according to nice hash it is reporting all my shares are 100% accepted and my temperatures appear to be at par with stocks settings?

Any long term issues with constant high H.W.?

[Rexmint]

 I will upload photos tonight

[GunsN]

What about warranty?
bitmain didn't accept overclocked machines

[Rexmint]

Has anyone pushed their L3+ this high or higher before?

And I wrote and quoted (partially above) I have had my L3 plus for almost 90 days now so if something should go wrong I believe the time it would take to get it repaired would wipe out Most of the games games as the profits / income or decreasing greatly Even if I hadnt voided the warranty. I figured the +20 to 25% in hash power was worth the risk and thus far has been.

 I didn’t get my batch and until late September I believe. The lesson I’ve learned is to get in the first batch or don’t get in at all. Although I think I will eventually make profit with this primarily due to the increase  in value of the coin’s. I’ll have to do a calculation later to figure out if it would produce 45 LTC  for the L3 plus and the power supply adjusting for electric cost.

 I believe my experimentation warrants even a small tip and  I would be happy with pennies just to say I got a tip.  I recently registered my ENS (Ethereum Name Service) for ETH.  Most wallets including myetherwallet support it.  Someone do me a favor and verify I set it up right and send me a couple US cent (or a few ETH lol) to Rexmint.eth

Just type Rexmint.eth in the address to field And the wallet should do the rest and there is no need to type out a long string of letters and numbers. I think it’s a really neat service something on the surprise BTC haven’t done yet

No not really. There was a blog post and a forum post about this months ago I got mine up to 700mh/s to see if I could do itI didn't make a post. It was proven the L3+ are really sensitive to OC and burn up rather fast above stock. Hell even at stock they are likely to go bad.

[Rexmint]

Don't do that you will kill a board soooo fast

How and why? Its temps are at par with other L3+ stock settings? Can you please be specific for me please. I thought HW were okay so long as effective hashrate was stable.

Thanks in advance.

So info I found from Bitmain...
Bold text in my response here forward
https://enforum.bitmain.com/bbs/topics/4959

-

Temps of the L3+ is different from previous miners, since there are four kinds of temps. What does each of them stand for?
Answer:

Temp(PCB): is the board, “I” is the board intake temp, “O” is the chip outlet temp.

Temp (Chip): is the chips, “I” is the chip temp on the board's intake side, “O” is the chip temp on the board's outlet side.

-

What’s the range of these temps of the miner?
Answer: We suggest the temp range of miner should keep within 25-80, and usually, it will be 40-70.

I seem to be safely in this range!

-

The temp of the miner only shows two, is it normal?
Answer: Yes, it is normal. In order to check the temp more convenient, the temp of hash board will be cancelled, only the temp of chips will be shown in latter miners. The board will only show the temperature of “O”, and the temperature of “I” will all be 0, which is normal.

-

Which temp of the miner should I focus on?
Answer: Temp (Chip) is most important, because it is air outlet temp of the miner. It will lead to high temperature protection, if this temp over 80.

Well below 80 so it says I am 'high temp protected"
Furthermore in the 'Miner Configuration' -> 'General Settings' -> 'Miner General Configuration' -> Setup
Stop running when temprerature is over 80℃ - I have this box checked!
Customize the fan speed percentage - I dont have this set but I could experiment and set it to 75-100% to see if I can reduce temps more. Thoughts?

It seems if I can keep the Chips Temp lower than 80 - at 59 now - but lets say below 60 or even 55 then all should be fine right?
The only thing that concerns me is the effect of the HW errors. I know with GPU mining (I know this is an ASIC not a GPU) these are not an issue until they effect hashrate and from what I can tell they are not. Is there way besides the lack of rejected shares I could tell if this effecting my hashrate and or earnings?

I came here seeking any and all advice.
Thank you for your input.

[taserz]

I got 3 L3+'s that had a board go on them at 462mhz. This is in an environment that that ambient temperature is generally  45-60F aka Nice and cold. Soon the environment will be freezing or colder.

[leowonderful]

The temperature shutdown thing doesn't work and hasn't ever worked on any Antminer unit, at least for me. Don't rely on it, I've seen miners go above my set temp by 5-10 and nothing happened. Under 80-70 is a good temp to have your miners at.

[Rexmint]

I am bit confused here. First you said you OC'd to 700 MH/s and that the L3+ was really sensitive and burned up rather fast.
Could you please refer me to your post and answer these questions if they aren't addressed in your post?
How and why? Its temps are at par with other L3+ stock settings? Can you please be specific for me please. I thought HW were okay so long as effective hashrate was stable.

Then you state you have 3 more or a total of 3 L3+ with one going out at 462 and the other at 700?

My ambient temp during the day is also 50-60F during the day and 30-45 at night in my garage with good air flow. I also run my Etherem mining rigs in their and they remain cool.

So are you down to 1 L3+? Or all of them with 1 of the 4 boards not working?

So the TEMP PCB is 1-4; 32 31 30 300

Fans at 100% are 6,210 and 6,240
When I didnt have a %fan checked the fans were at 3,120 and 3,180
So I think I am going to try setting the fans at 60% or so assuming 6240 is 100% and that keeps Chip Temp at 40 and 3180 had them at 59-54-54-52.

Ill post an update in a day or two.

AGAIN HERE IS A LINK FROM BITMAIN ABOUT TEMPS AND OTHER INFO FOR THE L3+
https://enforum.bitmain.com/bbs/topics/4959

[miropp]

What about warranty?
bitmain didn't accept overclocked machines

How Bitmain find, that L3 was overclocked sometime in the past?

[cryptofriendz]

I'm reading this for the first time. Can anyone share some links on overclocking the L3+. I obviously googled but didn't find something straight forward.

[Zorg33]

Don't do this.
You can clearly see that HW error is way too high. 6.2% !!
HW error is acceptable up to 0.5%, above that your effective hashrate decreases significantly and you kill you hw.
I have much experience in this matter I've been running and repairing ASIC miners since 2013.
Also keep in mind that VRM's are not designed to handle 30% more power even if the ASIC could handle 30% higher frequency.

My performance tests showed that almost all L3+ starts having too much HW errors above 462MHz. So 600MH/s is the top.

[Rexmint]

What exactly is HW? Nicehash seems to be paying more at 650MH than at 650MH. I get 100% accepted shares. Where is the 6.2% coming from?

Thanks for your input, much appreciated.

[Rexmint]

 
 Here is the email I sent to Bitmain

Nov 9, 02:14 CST

Very High HW Count...
Good afternoon, I have had my L3+ for about a month and a half now and everything seems to be running fine but my HW counts is starting to get hundreds per hour and thousands per day on all 4 of my boards. It does not appear to be effecting the reported hashrate on the Antminer GUI. The Chip Temps are all below 60 and the PCB temps are all below 50. What exactly is HW? Could the number that I am having which is much higher than anyone I have talked to you that owns a L3+ a potential short or long term issues as long as the temps are fine? Does HW effect the effective hashrate when mining? Could you please let me know what these HW are and what if any effect that have on my actual hashrate and if they could damage my L3+?

Thanks in advance
Mark

Here is the response I got from Bitmain about all this....

Dear Mark,

If your miner is hashing to spec then the hardware errors are no concern at all. The HW errors can be higher on one machine than another - that is not an issue.

Please let us know if you have further questions.

Best regards,
Barbara
Bitmain

[mattpatt007]

Typical Bitmain response. I wouldn't expect much help from them.
Following this thread. I think 650 may be a bit agressive... remember the key is to mine 24/7 / 365... if you can get 365.
If i mine at stock settings for 365 days, and you mine at 650 for only 280 days, then I MAKE MORE (standard model).

GL, keep us updated

[jstefanop]

Thanks in advance.

Dosent matter what temps your chips are...these boards are a serial powered chain controlled by a single buck. The mosfets are pretty nice for these, but at the power draw your approaching you will most certainly blow one of them eventually. Not to mention serial power designs definitely don't like to be run past amps they are not designed for.

Sure youll get an extra 100MH for a month or two, but whats better 500MH for a year straight, or blown boards after 6 months of running at 650MH outside of warranty and shit out of luck?

Slow and steady wins the race, even in crypto.

[Rexmint]

I have since went down to ~600 MH/s. My average speed is actually pretty close to what I was achieving with the higher settings. I have my GPU Rigs and L3+s out in my garage and with temps around 30-50 F (0-15 C) cooling is no longer a concern. It’s making about $1 (+/- 0.15) per hour on NiceHash at mining time. Thinking about bringing my GPU Rigs in to help supplement heat,

With the continued production or at least shipments of more L3+ batches and how each has had a great negative effect on profit I really don’t have much faith in these in 6 months (less really) so I think the extra strain and demand I’m putting on these is worth the risk to their long term functionality. I haven’t actually done the spreadsheet but I’m pretty sure I’ve made my $1,500 USD back on these especially since I’ve held everything I’ve earned and the value of BTC (and LTC, everything) has increased.

I’ll have to be on the lookout for the release of the L4+ with its 1.8 GH/s at 900 W and make sure to get in on the first batch.

[bitcoinexplorer]

Definitely wont be that much. Die shrink to 16nm which I'm sure bitmain is working on will be either 500MH @ 400 watts, or 1GH at the same wattage now.

[cod3gen]

Where did you get information about a potential L4+ unit?

My L3+`s is doing a stable 630 Mhs @ 960w

This is poor math. It MAY end up being true for the L3+ since it seems to be holding its payout value fairly well, but with the D3 for example, if you both got first batch models and one of you overclocked to earn 30% more per day, the overclock dying 85 days earlier would likely have earned MUCH more.

Again, not saying you should or shouldn't overclock, whatever works for you works for you, just saying that math isn't necessarily correct.

[millerfilm]

There is a reason the frequency is set as it is.

My L3+ is working very well, and has been very consistent. I am pleased with its 502 MH/s hashpower.

Looking into buying a L3+ and would like to know if it is worth it? Compared to normal GPU mining. Some people say it's too late to jump in, but if the ROI is better than normal GPU mining, why not?

[mano237]

If you dont want to invest much time, then put them on nicehash, get payout via btc and thats it. Btw the nicehash payout is pretty nice in my opinion.

If you prefer mining other coins directly and trade them away when there is a bump, you can probably earn more but you have to invest more time for searching pools, exchanges, trading, other wallets etc... It's up to you.

Roughly $17-18/day at the daily current bitcoin value on average. Check whattomine.com for a closer look once Nicehash is back up (if it ever is, they owe a lot of people money right now).

They might, but in a few years.  Just like what bter did years ago when they got hacked for the 3rd time.  It was 3 years ago but last year they finally gave me my lost $ not my lost BTC.  I lost 5 btc and got back like 1450 Yuan.  Bastards.  But something was better than nothing

Agree. If they can send us atleast some of our small amounts back, then I'll bring my trust back. Surely those guys must have way more BTC in their pockets?

They might, but in a few years.  Just like what bter did years ago when they got hacked for the 3rd time.  It was 3 years ago but last year they finally gave me my lost $ not my lost BTC.  I lost 5 btc and got back like 1450 Yuan.  Bastards.  But something was better than nothing

Yeah, no, if they pay me in USD then I'm not using their service again, because same deal. Nicehash is a MUCH larger organization, though, and now is different than then (for example, law enforcement not only knows what cryptocurrencies are now, they take them as seriously as straight currency theft; and for another thing, those accounts will be monitored, Bitcoin isn't quite as anonymous as, say, Monero). But yeah, if they pay me the cash that IS at least something, but if they pay me my coins I'd be more than willing to use their service again.

[greyday]

I think if they honor people's wallet balances, people will come back. I know I'd be willing to if I get my coins.

Agree. If they can send us atleast some of our small amounts back, then I'll bring my trust back. Surely those guys must have way more BTC in their pockets?

Probably, but they took a pretty huge hit. They also incur regular operating costs, which aren't small. I imagine that they may be able to work out some sort of payment schedule, however, like dedicate part of the farm to just earning payback funds until everyone is back to where they were at the time of the hack...

Or maybe they're insured and it's just a matter of working it out with the insurance company? No idea, I guess we'll see, but in the meantime I'm sticking to straight coin farming and regular payouts to my own, offline wallets/Trezor, thank you very much.

That's a good idea. If they can do payout overtime at least people will have some trust restored. Either way they will have to take a knock if they want to keep their business. Not sure if any insurance will cover such a loss through a security breach.

According to an interview with their CEO today, part of what they are currently working on is a plan to repay all the stolen coin to users. So if they follow through with this I am more than happy to keep using them for mining/payout when they're back up.

What sort of returns do you get? Are you mining other crypto's or directly on NH?

Looking into buying a L3+ and would like to know if it is worth it? Compared to normal GPU mining. Some people say it's too late to jump in, but if the ROI is better than normal GPU mining, why not?

Difficulty is going up on a regular basis. I'm glad that I had my L3+ up and running the same day it was delivered. I made 1 LTC in 6 days. Now, I am just hoping that I can make my next 1 LTC in 10 days.

I used to be faster than up to 60% of those in Litecoinpool. Now, I'm down to 37%. Lots of people are out there crunching away.

It's going to get tougher and tougher. Bitmain's next release of Antminer L3+'s aren't until March.

You should definitely get more hashrate from an ASIC miner like the L3+ than with a GPU rig, unless you have one beast of a GPU rig! :-)

Run the calculations and see what you think. Meanwhile, buying LTC right now is a very good idea. Buy it and lock it away.

I made kind of the mistake of going mostly in on mining. I have 5 TH/s of Bitcoin Cloud Mining on Genesis that went active on Halloween. It is doing well. And, you can switch mining to other cryptos like LTC. I am waiting for my next BTC payout, then I am going to test going 100% with LTC and see what kind of returns I get. Genesis rarely offers Cloud Mining contracts, and when they are offered, they go VERY fast. I was only on my fourth day of studying crypto, and was glad that I had the presence of mind to grab up what I did. Of course, I wish I had gotten more! But, with my limited knowledge at that time, I am glad that I went for the 5 TH/s.

But, buying crypto and locking it away should be part of your strategy.

I have carefully documented my experience with the L3+. I shot video of my unboxing and hooking up the Antminer to the PSU. I will post that when I get a chance, and put the link on here. I am also working on a written guide detailing my experiences and my personal advice. I will post that on my blog at the address you see below in my signature.

There is a lot to consider. Power requirements, noise, heat, and ventilation. L3+'s can be run on 120V. But, they should run more efficiently on 220V. That is my next step: Seeing if I can get a 220V outlet figured out.

I will try to post what I can when I can. With the holidays going on, I am quite busy at the moment!

If they can get that right and pay the miners what were owed to them, I see at least 50% of the miners heading back. They should also revisit their fees, as people started using other "easy" miners and saw higher returns.

True. They should certainly revisit their outside wallet fees, as if miners could have been paying out regularly at a cheaper rate (or just equal to internal), there'd be less stolen and less to figure out how to pay back (I wouldn't have had as much in my account if I wasn't trying to minimize fees).

And depending on the platform they re-open, I could see more than 50%, but yeah, there will definitely be a large percentage who just will not trust them again.

I will try to post what I can when I can. With the holidays going on, I am quite busy at the moment!

Difficulty is going up, but so is coin value. Significantly. So while I am earning less on my L3+ in actual litecoin right now than I ever have, I am earning more in USD equivalent. It's all relative, unless it devalues significantly.

They will be more efficient on 220V, but do the math. I think it's something like 8-12% more efficient, so figure out how long you plan to run your L3+ (lifetime), the cost of your electricity, do the annual math on that, then subtract, say, 15% to be safe. Then do the math on what adding a 220V line and outlet will cost (if you're handy, then what the parts will cost; where I live, that worked out to around 1/3 the cost of hiring an electrician, your mileage [and homeowner's insurance or rental agreement] may vary), and figure out if it's ultimately worth it.

For example, my slightly overclocked L3+ on a 120v pulls around 850-900W (will retest that soon). So let's say for most expense, 900W. For me, actually, I can tap into the 60A 220 line running to my heater if I want (since my miners make my heater run rarely, and it runs well under the 10.5kW continuous safe rating, so my cost is basically an outlet box, outlet, and new cable for the PSU; I'd estimate that at maybe $100).

SO (and keep in mind that the voltage may be higher or lower than 220, but will be in that general neighborhood), roughly:

900*24*365/1000=7,884kWh

My electricity is .11/kWh, so:

$867.24/year, or $72.27/month

15% of that would be $130/year

So independent of coin value, if I plan to run my current L3+ for more than 10 months, it is potentially worth it for me to swap to the higher voltage (the bonus being I can actually test the exact difference by using one of my heater lines before I even do any work, all I need is an adapter to do so). HOWEVER, to do things with proper permitting to code by a licensed electrician would be significantly more expensive, and ultimately not worth it IMHO, unless I planned on building a farm large enough to require its own breaker box; then a series of 220 line would make sense, since the wiring was being done anyway. I do not currently plan to, so yeah. For my purposes, the small amount of difference is not worth doing it.

Now, if I plan to replace my L3+ with another ASIC miner in the future, which I may or may not do, the long term benefits may very well be worth it. But for now, I'm not planning to (especially since I use renewable energy and am having solar panels installed, so wasted electricity is becoming less of an issue for me, and I use the heat to heat my house anyway [my heater is also electric], so there's actually no loss of electricity in the winter).

Conclusion: if you will use the 220v line in the future, it is worth it. If it's only for the lifetime of this L3+, then the value is more about whether or not you want to be more efficient, not necessarily profit and loss based. My opinion only, and I'm neither an electrician or a math professor, so grain of salt and all that.

[OGteamcrypton]

very interesting topic chaps. Im in for the ride and interested in the limits of these things. I think no one really wants to blow a board.... but man is it fun to mess with the settings =)

[stevebills]

Sorry I may have not been as specific as needed.

The L3+ comes at stock set at 384M frequency (I think) which equals out to approximately 504 MH/S.

My first overclock I had it going around 600 MH/and I believe that was at 440-460 frequency.

As you can see in my post where I outlined the settings I have overclocked it to 500 frequency which is given me approximately 650 MH/S.

My question is if anyone has set a frequency of 500 or higher and if so if they have seen any issues? The only issue I see currently is the high HW account but at least according to nice hash it is reporting all my shares are 100% accepted and my temperatures appear to be at par with stocks settings?

Any long term issues with constant high H.W.?

after 2 months or less it will start to fail and need to be returned to Bitmain i tried it wore the t shirt
dont bother i have blown 3 antminers this way

[fanatic26]

Overclocking ASICs is always a really stupid move. Especially when you have no clue how they function and think that the temperatures are all that matter.

P.S. Stop being lazy and using nicehash, sit down for an hour and figure out how to do things the proper way and you will earn much more in the long run.

Not really. Think about when the D3 first came out. If you'd overclocked it to the highest stable hashrate and left it running back then, by the time the second batch shipped you'd have made more than you probably will with any batch since on any setting. So it really just depends.

I have my L3 overclocked to 600 with zero problems (running for a couple months now), my D3 uses BlissZ's mods and runs underclocked a lot of the time, but will be overclocked when it moves to the basement. If I had an S9, though, I would leave it at stock, because that will be a consistent earner until something new comes out for BTC.

I mean, there is certainly something to be said for longevity, my S5 still earns a steady profit and heats my living room. But just by the math, the $2-3/day it earns is nothing compared to what it earned when it was king of the block, so if I had it back then, overclocking would have likely resulted in more income.

YMMV. I'm mostly conservative with my hardware (except the L3), but I totally get the logic in overclocking.

(also Nicehash is nice when BTC drops in value, but in general yeah, I totally agree: mine coins and support blockchains of coins you believe in!)

[Gearhart]

I have 5 machines...1 machine I am testing at 475 MHZ it is kicking out about 621 MH/S and the chip temps are 58, 56, 55, 57 with my fan speed at 100%.

I haven't had any HW errors yet...been about 1 week on it at this frequency.
