So Lt how can i tell how many volts i'm putting through the card? Afterburner and GPU-z are both reporting a little over 1.1 volts but other people seem to be putting way more through there's. how much is going though your at stock?

Stock is about 1.15v on a 290P Dave, though it fluctuates so it can go lower or higher. +100mv is perfectly safe on air as long as temps are kept in check. I use +200mv on my reference cards for quick benchmarks.
 
yeah but you can only measure it in action, idle it will be lower, then under stress lower also because of v-droop. neither afterburner or gpu-z give you fixed value, only the graphs/monitoring

I don't think there is anyway to find out specifically, although Anandtech have some interesting numbers. My 290P cards appear to be around 1.15v at stock.

First, let’s start with voltages. Ideally we’d use VIDs here, but due to the fact that none of our regular tools can read AMD’s VIDs for the 290 series, we’re left with what works. And what works is GPU-Z, which can read the VDDC coming off of the IR 3567B controller. These aren’t “perfect” numbers as we don’t have the ability to factor out fluctuations due to temperature or the impact of vDroop, but they’ll work in a pinch.

To that end you can immediately see that the 290 starts off in a weakened position relative to the 290X. Second tier products are a mixed bag in this regard as sometimes they’ll be composed solely of chips with damaged functional units that can be shut off and then downclocked to operate at a lower voltage, while in other cases they’ll also include chips that have worse leakage and power consumption characteristics. In the case of the 290 we have the latter.

So did a comparison in firestrike extreme between my original score and the difference if I moved the cards into x8x8

so it went from 8116 to 8721. It also topped out at 93 degrees witrh my fans at full and the side off. Clearly unusable but it does show the difference if my board had an extra x8 slot at the bottom
 
oh yeah, i just think my stock vid might be quite low. Max volts i'm seeing with +100 is 1.18 - ok i had one blip of 1.22 volts. Strangely with the extra volts on the core the memory seems to be performing a whole lot better, got it up to 1500 last night trying to crash it playing bf4 and it seemed to play fine...

Yep core voltage is tied to memory clock on these cards.

What asic is your card?
 
how do you find the asic, as i think it has some tie in to the voltage dosent it ? trying to debug whats wrong with mine atm

Higher ASIC = Lower power consumption and run cooler
Lower ASIC = Higher power consumption but overclock higher.

Yours has a Higher ASIC, mine has a Lower...

Edit. you edited out the question :o

But it says under overclocking Higher on stock air cool should be better on Higher ASIC?

Edit
Yeah I noticed the images answered my question :p
 
:D ^^^^^

Yeah, because a stock cooler can keep a lower power consumption card cooler.

Lower ASIC cards are more leaky, they can handle more volts so they can overclock higher as long as you can keep them cool.

Thats why it says "Low = Higher overclocking on Water LN2"
