As above there is a "band gap sensor on-board" so no external sensor needed for LM75.

I still think the temps on the advanced page are from the die itself not from a sensor elsewhere on the board.

Don't mean to question your credibility Avenger as everyone knows that your posts are always fact based ~L)L~ but I would like independent confirmation of the device identity. For both of them.

If they are LM75 devices, then they are measuring the board temperature at their location and are not using a temperature diode on the ASIC. If they are some other chip, then they may be using a temperature diode on the ASIC chip.

Could someone please provide a nice close up showing these 2 devices ?

Yes, I misread your statement to imply that the basic LM75 had the onboard sensor, but the 'A' rev that you were looking at previously did have those provisions, and that the schematic you were posting was of this alleged 'A' rev.

what we need these one?
lm75???

just a little touchy are we tulip ?

That now leaves me wondering why there are two LM75 devices adjacent to each other.

This is shocking!  Do they think that because they shipped at least one Neptune by Q1/Q2 that they have met their timeline obligation?  That is totally absurd.  'Ontime and overspec' is their claim with this performance?  What if they take another 12 months to deliver the remaining Neptunes?  They still claim to meet their timeline?  I've got a feeling customers aren't going to stand by forever.  Probably time for serious action.

Well excuse me for not reading every post in this thread before I ask a question. Anybody with half a brain could figure out that if I had seen Tulip's comment I wouldn't have asked the question.

You Neptune owners are a touchy bad tempered lot. Can't imagine why. Better luck next time fellas ~L)L~

So, in conclusion, if it is a LM75 then yes it is measuring the board temperature in its locale, not the on die ASIC temperature via a temperature diode on the ASIC. Is anybody having trouble with cooling fans not operating correctly ? Is anybody having trouble ROI'ing their Neptune ?

My 'workshop' is just a wire rack in my kitchen.
I live in a small 2 room shoe.

My main design goal for first stage with the Nep cooling was remote heat exchange.
Another main factor was low downtime.
I built the loop and modded a cube at a time while the other 4 hashed away.

It is very much a temporary prototyping environment.
The Hoopiter had a similar long transition into a neat case.
If they runnin no hurry.

No nightmares. the Nep system is just over 3L of H2O.

YMMV

Does anyone
Under volt Neptune
And run at 500 mhz

It amazes me to see some of you guys still have faith in KfC.

It's over 3 weeks since they tried to sweep under the carpet they ran out of chips. Plenty Batch 1 customers are still waiting. Not a single update for customers to let them know anything about this situation in over three weeks.

They fed everyone lies claiming they would continue shipping and the fact they had no chips was not a problem  

Anyone waiting for Batch 2 who thinks they will get a bonus for the wait really needs to think again You don't know how kfc operate if you think that.

It also seems they are taking 2+ weeks to RMA anything. No doubt, taking their time and looking for ways to blame the customer and not their hardware.

If they were some crappy ebay seller selling hairbrushes with led lights in the handle or some other cheap mass produced crap, it's the kind of customer service you'd expect.

But it's an appalling way to treat customers who paid $10,000 each (or more) for knc's hardware.
