look at the core voltage on run4 ... rolleyes.gif

could you repeat run4 with 1.025v on the core? biggrin.gif

No, I noticed that. It seems to detect the card voltage draw. So if my memory is at 1.15, it will detect that. Not the 1.025 I had the core set for.

that doesn't make sense ... that power draw Gap cannot be because of just memory voltage

compare run1 vs run2 = run2 has +100mV on memory while using just 2.5w more...

Alright, I'll rerun it, but I think it'll be the same. It's going to be a minute though. I'm testing -13% (1100) GPU/Stock Mem voltages for guys in the news section. I'm down to .875V (-275mV) already if you want to know.

Nice

Looking forward to it 😁😁

To answer your question already. VDC is showing .925V (where my memory is set) even though I have core voltage at .86V. I looked on my last run real quick.

maybe the card doesn't allow the Core Voltage to be lower than memory voltage

What you trying to prove is absolutely off the table

Just compare the power consumption and core temp in run3 and run4

If mem voltage had any impact on core temp then we should've seen lower temps on run 1 vs run 2

If you want to undervolt further , i suggest downclocking memory to 1750 which is on par with 4GB model

Can't, without a 3rd party that is. Wattman only allows stock clock and higher.

The driver crashes at the lower core voltages (<.85) though, so I think it's just the GPU-Z interface.

Damn... So basically 0.925 is the lowest voltage you can feed the core

Just set that and see how much you can OC from 1100 core...

The efficiency is gonna be on par or better than Pascal i think... (Perf/watt) ✌🏻️
