@guzmanpintos@SatStackingPleb ^ this is the answer. The threshold voltage of the transistors shift as temp changes. Keep in mind, temps on most Bitmain FW/Boards is an est of the die temps as they use a lm75 on the board + offset. If you really want to see take a look at a BM1368(S21) which has on-die temps
@skot9000 @kevinaltairtech @denverbitcoin@CryptoMinerCHR@ndgo1370@zbomstaz I know @guzmanpintos and LuxOS has previewed the amount of data/samples required to build an accurate model

The APW17 introducing accurate power reading over the PSU protocol was a welcome addition
@skot9000 @kevinaltairtech @denverbitcoin@CryptoMinerCHR@ndgo1370@zbomstaz You can go all the way down the rabbit hole here..but to keep it simple. APW12 doesn't have any current reading capabilities exposed so when we do power estimation in ePIC FW (and most other FWs) we do a power estimation based around 3 variables (Voltage, Freq and Temp)
@keegreil@SatStackingPleb@ePICBlockchain@altair_tech@zbomstaz We wanted to be on the safer side and make sure that the setting wasn't accidentally enabled for miners running at scale in a normal environment, but this is a good time to revisit this.
@SatStackingPleb@keegreil@ePICBlockchain@altair_tech you can, just need to be a bit careful. The fan headers are in parallel of each other so if you do want to use the connector you'll want to make sure the SENSE line is disconnected on one of them (FAN1 MOLEX -- FAN1 4pin).
@skot9000@keegreil As you suspected I expect it to most likely the DHCP discover and some network init. If you see anything else and have any questions just ping me
@keegreil no dev-fee, no phoning home. give the UMC a try. API fully documented and open. Also welcome the packet audit! If theres something that shouldn't be there that we missed will address it.
Here’s what we’ve been up to

15 Exahashes ✅
One of the largest Hashrate agreements✅
New upgradable platform ✅
Boom!!

@OGBTC@marcfresa@perryhtee Don’t worry I’ll like your post too, just not the one that is factually incorrect. Happy to talk chip design with you anytime as always
