gpu-z power prefcap reason pwr

[INDIANAJUNE2]

hey guys , sorry if this is a noob question but I just got a factory overclocked 2070 super and I notice in gpu-z that the prefcap reason is usually grey for idle with little slices of green for pwr every now and again. on my old 1070 it pretty consistently said vrel. so I just want to make sure that this is ok/normal. if I understand correctly it just means the card is hitting its maximum power (which is a good thing ) and I can up that in say afterburning if I want ? I mean I'm getting good performance, if anything slightly bottlenecked by my i7700k.

This is normal behaviour. Idle perfcap actually means your GPU performance is capped because it's simply doing nothing; if it were at maximum power you'd see the power consumption figures rise to 100%. I don't use Afterburner so I can't say whether you could increase the power limits in that software but I suppose it ultimately depends on the flavour of GPU you have. If your 1070 had a voltage reliability perfcap, it's most likely because it believed it couldn't automatically boost clocks any further without becoming unstable, which is down to everyone's second favourite lottery.

hey thanks for the response. its was actually the slices green pwr bars in the picture that I guess I was concerned about or just wanting to know if it was normal. not sure if you know or not ?

After doing some more research I think you actually answered my question and I was too naïve to understand So thanks. I was concerned With the green pwr slices because the card down clocks by 10mhz when it hits those. But if I’m not mistaking this might all be signs of the bottle neck with my i7700k especially the idol Grey. Which is good news cause I plan to upgrade. Just wanna make sure he new card is ok
