Yup, that's how it works. evga Voltage Tuner is actually a separate application, so changes made there are not part of the 'saved profile' in PrecisionX. LAME, but ... that's the problem here. And voltage tuning in AB (which DOES save voltage changes) doesn't work at all, so ... until that gets fixed, or evga creates a link between VT and PrecX, we're stuck with manual overvolting on each startup if we want higher volts.

yeah, i think that was the problem i'm having. i've experienced it a few more times since last night. i can't pinpoint what causes it, but seems like it just goes back to stock voltage at random times.

Does your clock speed always go down 1 if you lower your overclock 1? I'm lowering my boost from 98, which gives me a 1228 core, to 97, and I'm suddenly getting a 1215 core?

How long does everyone run Heaven for their Benchmarks to ensure Stability? I am so confused with my 670......I cannot seem to get past +114 on my GPU (Which is 1273Mhz on my Card) and +90 (which is like 3050Mhz) on my Memory.....Now I am happy with my GPU overclock, but not with my memory overclock, I should get MORE than just +93...And I can run those settings (+114GPU/+93Mem) on Heaven with Everything maxed out at 1920x1200 for 2+ hours...But if I go higher on My Memory I crash out within about 30-45 minutes.....My temps never go higher than 64 degrees...I am starting to wonder if this is an issue with EVGA Precision.......I know my card is not bad because I ran Heaven overnight at stock settings and had no issues.....I might try Afterburner to see if there is a difference, I have heard that Precision can cause instability......What do you all think? By the way my card is a EVGA SC 4GB 670......Only had it a few days, just trying to hit my sweet spot....

For some reason, my EVGA's max TDP is 80%, even with PT + 145%

I want to OC it a little bit more!

1280mhz is not enough!

It's the FTW edition and I have a custom cooler, rarely goes over 55c, let alone to as point where it'd throttle.

Could someone please help me out? My score keeps decreasing with every Heaven benchmark test even if increasing or decreasing my offset or even leaving it the same. I'm following everything in the long method guide. Perhaps someone with Team Viewer could give me a hand? I would appreciate that.

Thanks.

For what it is worth...I seem to be getting higher clocks and more stability using Afterburner rather than EVGA Precision....And I have an EVGA card....

I've noticed my OC is stable (once I found a stable one) just by leaving the voltage to adjust on its own while gaming - I've been having no troubles at all staying at my max boost clocks or remaining stable. The card ramps itself right up to 1.175 volts anyway once it hits its max boost, which usually happens when I blow something up in BF3 then the max boost and voltage just stay pegged for the rest of the multiplayer session, unless I go hide in a dark corner, in which case it will downclock itself until I get moving again.

My question is, do all of you HAVE to manually adjust the voltage to remain stable with your max OC, or are you just doing it to avoid the card downclocking itself on the rare instance that it might decide it doesn't need as much juice? I just keep my power percent pegged on max and it remains stable regardless of what I set the voltage too. I've just been leaving mine to do what it wants and I've been stable. Interested to know why we are adjusting the voltage manually after finding a stable OC, and how many of you need to do that to be stable at max OC - if any..

thats an interesting question that i hope someone could better answer. i've read a few posts where people stay at stock voltages and could o/c pretty high. but then in my case i could not even manage +20 offset at stock. but after i manually raised the voltage to max i could do +35. its quite confusing since it appears no two cards are alike. there is so much randomness involved.
