7970 Vapor-X Overclocking?

post #1 of 21
Thread Starter 
Reading various things about real voltages not being read unless you use utility X (like a MSI Afterburner)...

I used EVGA's utilities with my 560 Ti 448, up to 895. But with the Sapphire 7970 Vapor-X I've been reading people using Trixx 4.4.0b which I have but then I can't read the real voltages since I don't want to have multiple overclocking software open right? Or if I don't touch anything on MSI Afterburner I can use that simultaneously?

What utilities should I use to see how far this can go?

and the GPUZ voltage isnt incorrect, its actual measured voltage. It includes Vdroop.

Target Voltgae - Vdroop = Actual Voltage.

Just for clarification

Target Voltage is what? What software is telling the card to try to output?

Vdroop = The difference between target and actual

Actual is what I'm interested in watching to not go above 24/7 air limits?

Yes target voltage is what your telling the card to output, vdroop is in rough terms the ammount of voltage lost when the card is in use, due to leaky circuts power phases etc.

As per your question I would stay within 1.2-1.25v for daily use and only use 1.3 for benchmark record runs etc. Personally I would stay as far under 80c on your core as possible and keep the VRM temperatures below 90c to make sure your card lives a decent life.. also I've noticed on my 7970 I start getting unstable when my core passes 82c. MSI Afterburner has been a great overclocking utility for me, and I also use HWinfo64 to monitor my VRM temps.

a clarificaion: Aida64 will read the correct DEFAULT target voltage for the current poweplay level from the ADL library. It will continue to show the deafult, even if you increase it with trixx/ab.

I have posted in the aida64 forum to try to see if Fiery will add a new sensor for tweaked voltage,

Thanks mate, if you have a link to the topic I will also add to your request as it would be real useful for me, as I monitor this on my keyboard, so the target is useless to me when benching.

I do as well on my G-19,

Thanks mate, will log in later and add the same request.

does anyone know when voltage/current overprotection kicks in on these cards? as in, whats the voltage limit we should stay under to maximize our OC without throttling??

Ugh, Afterburner does not display real voltages either... till you modify it.
