I'm going to ignore your ignorance on this one, I have several years in electrical resonant research and development, as does my brother. We have over 100 members in our study group, which spans the globe, and has been in operation for about 5 years proving what you say is BS. Many new energy saving/producing products will be hitting the market soon as a result of some of our members hard work.

That's a strong "yes" on your belief in pyramid power then; shame Neptune is cubes.

"it's called resistance" and it could increase with load to a possibly significant level on a low voltage DC circuit; that's the reason your supply is AC at a much higher voltage thus effectively eliminating the problem. You can argue that resistance does still increase with load and that's true; just not to a remotely significant level on an AC mains supply.

There is ZERO chance that any variations on the AC supply will make it through a modern switch mode PSU and have am impact on the DC output; you couldn't be more wrong.

"the magnetic field induction which moves the current"... just no.

Did you even read the post? Lousy power? Not applicable.

I read the post; it allowed you to demonstrate your lack of knowledge on the subject very well.

Are you also a believer in pyramid power by chance?

Pyramid power... lol, that's the word I was looking for, thank you.

Phoenix.. I asked you before.. do you have any data about what you've actually saved?

Advice to all: If your PSUs are built in the last decade and have an ENERGY STAR rating, they probably already have PFC and this will not help you much. If you are using 10 year old PSUs that probably has a switch that you have to flip to use 120V or 240V on the input, then buy a new power supply.

Are you working with, or at least following, the EPA's work by chance? Because they covered this a decade ago  and practically all PSUs include their own PFC. In fact, the program was so successful that the EPA has sunset the program. This helped manufacturers reduce PSU failures and returns so it was a no brainer.

Can I get my resonant electrolysis pyramid in red please?

Yeah the Navy is doing some cool stuff in their research labs, but electrolysis of seawater is a different topic. If you want to power your miners on seawater, game on dude - send me the specs. I read the article, did you think PFC meant pure fucking catalyst?

If you're not interested, move on. PSU's do not contain PFCC's, lol. They are a totally different animal.
Pyramid power eh?   Don't you have one?  lol

Almost all PSUs built in the last decade have power factor correction:

This helps sanitize the thread and condense it some to relevant, intelligent discussion:

"This user is currently ignored."

Arguing with him is why this thread is over 1800 pages.

Pointing out all of the parts where you're wrong and making a fool of yourself is a fool's errand and I'm no longer going to waste my time doing so.  You hardly have any idea WTF you're talking about, like usual.  Maybe instead of wasting all your time "researching resonant blah blah blah" you should go get an Electrical Engineering degree so at least you have something more than ill-understood "research" to provide back to society.

It's like contract hashing.
It does work but is not cost effective typically.

Buy some caps and open the panel and put them across mains.
Extra 240 breaker good place for them.
Keep the investment small and cost amoritized by 'education' of if it works or not.

Won't save what it cost for the pros to even show up, much less get out of truck.

YMMV

Here's something that won't help haters and trolls : Firmware 1.00 for Neptunes
5-10% speed improvement. We'll see on long term.

There is often humor for me in watching it play out, but I usually resist joining in the fray.

I broke in hoping to spare someone from spending money on PFC equipment when a decent power supply is all they need!

[murraypaul]

PFCC's make everything run more efficient by enhancing the magnetic field induction which moves the current, especially if your home is full of appliances which use capacitors, making all of them run more efficient with this magnetic field. It will also make those PCI connections COOLER for the same reasons.

That sounds like psuedo-science garbage, and isn't backed up in any way by the link you have given.
Can you provide any support for your claims?

It's not entirely pseudo-science.  He's missing some key parts of the equation and using big words to sound smart.  In essence, he's regurgitating things he's read, but doesn't fully understand.  Now, if he comes back here with a bunch of calculus derived from something like, oh I don't know, Maxwell's equations, then we can start to take him a little more seriously.

That part about DC connectors and heat is 99.999% dumb though.

Thx for the links guys.

Lots of Communication errors in cgminer display
Looks like it is just more/different reported noise.
NOT detrimental to GH compared to rc6.

I'll let er soak for 12 hours and will return with avg and pool results.

I use 3.6T as perfect and compare to it BTW (for 7200 @ 500MHz)
It is the current bar AFIK

rc6 had around 2% of where did it go??? was not reported in HW errors.
HW error has increased from 0.18 to 0.8%
What I expected with stock voltages on everything.
(28nm as my expectation reference)
Treat them individually and they more productive.

CPU load  is around 25% now as opposed to 100%

Positive overall experience with FW 1.0 upgrade here.
It has what we seek, a few more GH.

EDIT
If ya do heat a VRM till he goes on strike,
no need to power cycle for negotiations to return to work.
The Advanced page works great now.
Excluding the limited clocks

YMMV

The link in my earlier post has a more articulate description of power factor than what Phoenix tried to provide:
http://power-topics.blogspot.com/2008/02/what-is-pfc-and-why-do-i-need-it.html

Good PFC can also reduce ripple, so I agree with giving 0.001% credit where credit is due.

Different PSU or two other options..
-lower the clock speeds on the advanced tab (change your pool settings if you can't do this before it shuts off.. Kurt's troubleshooting guide has the complete steps)
-buy/build a connector that will allow you to bridge two rails from the PSU to the cube.
