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

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

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.?

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.

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 forwardhttps://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.

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.

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.

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? --- I just turned the fan up to 100%, which I am not going to keep it at that and here is it readings... Elapsed MH/S(RT) MH/S(avg) 7m32s 650.845 609.57 Chain# ASIC# Frequency MH/S(RT) HW Temp(PCB) Temp(Chip) ASIC status 1 72 500 163.42 268 I:0 O:32 I:0 O:39 oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo 2 72 500 162.76 167 I:0 O:31 I:0 O:38 oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo 3 72 500 162.02 412 I:0 O:30 I:0 O:37 oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo 4 72 500 162.65 207 I:0 O:30 I:0 O:38 oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo Fan# Fan1 Fan2 Speed (r/min) 6,210 6,240 --- So the TEMP PCB is 1-4; 32 31 30 300 And the TEMP (Chip) is 1-4; 39 39 38 38 ---- 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. Thanks all! ----------- HERE IS THE PHOTO / SCREENSHOT OF MY L3+ RUNNING AT 500M FREQ AT 650 MH/S FOR 25.5 HOURS https://ibb.co/hQ6V0w ---------- AGAIN HERE IS A LINK FROM BITMAIN ABOUT TEMPS AND OTHER INFO FOR THE L3+ https://enforum.bitmain.com/bbs/topics/4959

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.

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.

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

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

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. 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.
