One thing is for sure... your Monarch numbers are no longer valid.

Spondoolies is unlikely to meet those numbers at teh wall either; more like +10% power consumption.

Same goes for the S3 that's more likely their 12v power consumption so +10% at the wall?

Thank you for the reference.

From my admittedly biased position I'd say the average Nep is 3.4T  at a squink below 2kW.
Completely stock PARTS and tuned gets ya to 3.5T @ 2kW.
3.55-3.58T is doable with some added airflow, same 2kW @ wall BTW.
(the gains are lower errors not faster clocks)

To accurately compare would require seperating 110VAC from 220VAC PSU.
Also need to take into account PSU efficiency and it's % loading.

Ideally all units tested on same PSU.
Next would be all units mesured under 'hopefully' similar conditions.
Next would be at least reporting the conditions during measurement.

The reality is we don't have the luxury.
The boxes are or should be too busy hashing to stop for ideal testing.

I have no idea what 'average' is but I have better numbers.
I am also under the impression from posted 'Advanced' pages that my numbers are not ununual.

Repeating, I know I have a biased opinion so take this post as just that, OPINION.
I'd say 3.4 @ 2kw is very common for typical customers.
My numbers for reference,

Please note, I don't think your collection is biased, just that my opinion must be as I own one.

Very well done long term effort!!!
I appreciate your contribution.
Thank you for your time.

I also agree that 3.4th at just over 2000 watts is correct out of the box stock.  Still using the original firmware. On my Neptune I get 3.4ghs one one antec 1300w psu I have 3/5 pulling 1250@120v watts and on the other 1300w 2/5 and controller pulling 780 watts@120v

As for spondoolies speed 4.45 seems to be the average at this time.

And I will add the new BFL monarch pricing as a new line. There are still a few who paid a primium for aug 2013 monarch pre-orders.

I notice you have 2 cubes pulling 390 each @ wall assume controller rides for free.
Your 3 cubes pull ~415 each no freeloader controller.
390 x 3 would be 1170 W.
If you moved one of the 3 over you could determine if it is,
A individual PSU efficiency issue,
a PSU near max is much lower efficiency on both or,
a hungry cube.

I will have to try 1 on 1psu later. However it may also be due to the cercuit not giving 120v but rather 116v

Hi Together,

Which bitches shh batches are shipped at
moment?

We had the nonpublic batch and batch 1 & 2 and bonus bitch?

If knc dont refund neptune buyers then surely they should be investigated by a company trading authority,they just dont seem remotely care from what i have been reading...

from what I understand they don't even acknowledge there IS a problem..they blame the power supplies (yeah corsair 1200i units are so 'not mainstream')

usual bait/switch/stall .....must have paid for the BFL seminar ....I mean really ...like people with Neptunes can't read specs recommended on the power plug they used

they were cheap but hey with the 90 day warranty now...they can probably skate on some of this till that 90 days is gone and your stuck with it

miss the old KNC.....frigging evil KNC twin figging took over the kingdom me thinks

You say 90 day warranty, but didn't we all get the 12 months as stated when we ordered? I never agreed to a revised T&C knocking 9 months of the warranty!

[Fixx]

Hi guys!

The Titans will be?
Something tells me that it is necessary to demand a refund and the Titans.

Good luck with that.

Now go read the terms and conditions of the sale (like you should have done before you sent them your money)

Sorry to be a dick, but this has been covered in this thread a hundred times

er no clue ..was in trusting mode when I got the Titan on a Neptune CA xfer...it was 2 weeks or so after this that all went to hell at KNC and they started the current slide
i miss being happy and clueless about KNC ...well now that it is the evil knc with no refunds...I'd assume they would try to get us and say it is only 90 days

if you have some kinda link I'd sure like to know I have a batch 1 Titan order...provide a link..but likely they will just change the TOS to 90 days and claim they
can because the product does not exist yet...or some other silliniess

anyway if you are correct shoot us a link and/or some info on such..this make come in handy ....esp if the Titan too has power plug issues

but me was stupid and happy back then .....rude awakening happened 2 weeks later or so if I remember correctly as the slide started to BFL at KNC

admited KNC fan boy when I got the Titan .before in the next few weeks KNC went to the dark side....anwyay the no refund was there ..that I knew about
as to the 90 day no idea if it was 1 year or 90 day..I was a first batch Titan buyer thou

anyway just fessing up!

[aasl]

what? now knc only provides 90 days of warranty?!

Regarding that they completely ignore specifications for the voltage regulators as well as power supply cables, I'd say its generous.

Hi ,

Yes, the warranty period for your order is 12 months.

I believe that you need to RMA this board, I will send this request over to our RMA team to issue you with an RMA number.

I know it's 12 months and have tried to return a cube that has a dead die on it only to be told that it's not covered because the machine as a whole is still slightly over 3TH. I have since had a PCI-e socket melt and KnC have publicly blamed power supplies and cables for this (which is not the case).

I am using the 16AWG cables that came with the AX1200i; the fault is clearly with the KnC "design" and not the cables.

Look at the ant S3 for instance; they have four PCI-e sockets per 350w machine to meet the 100w spec per PCI-e 6-way. KnC must have saved <$0.50 per cube by skimping on power sockets which makes no sense on a $10 to $13k machine.

Not a happy customer.

What makes you think the AX1200i comes with 16AWG cables? I've never seen one with anything other than "type3" 18AWG cables. I've seen quite a few of them as well.

I've also had them melt/smoke/burn spectacularly: http://imgur.com/a/UUpEG
