Bug reading Haswell Offset voltages

[Nalika]

Hi Martin.

When using a negative offset, for example -100mV for Cores HWInfo32 shows 1.945V. I suspect you are treating the offset as an unsigned number instead of signed.

Thanks for the report. Please copy-paste the exact line where it shows this invalid value and tell me the exact setting in BIOS for this case. I'll fix it then.

I see you have now fixed this in build 2063

Build 2060 11-Dec-2013

Build 2063 21-Dec-2013

I think there's still a small problem with both positive and negative numbers in that each bit should be 1/1024th of a Volt, not 1mV (1/1000). The two screenshots should be -80mV I believe. Also reads -82mV in build 2075. It's only going to make a small difference so not a big thing.

Thanks for the feedback.
How are you sure about the 1/1024th of a Volt ? Documents are not very clear about the format used to report these values.

Well if it's not then XTU is wrong. Offset is given in steps of 0.9765625mV which is 1/1024V. Remember I didn't say I was sure, I said "I think". Unfortunately that's the best I can offer you.

 

[Martin]

OK, I think you might be right, so I'll change this in the next build

Looks like HWMonitor got the same doc's as you.

Might as well mark this as solved. If I'm supposed to do that idk how. :huh:
