I have a 670 FTW and think I might have a dud.
Out of the box my boost is 1085 with a Keplar boost of 79 giving me a max of 1137. From what I've seen here on on the EVGA forums, this is a lot lower than many other FTW cards.
I followed the guide to the letter and the highest core offset I can achieve is +58. Anything higher crashes Heaven. This is with a power target of 145% and voltage set to max.
Here's the weird part. I can stabilize the +58 with 116% power target. That would lead me to believe I should have a lot of headroom to raise the clock. But I still can't get over the +58 regardless of the power target and voltage setting.
I've tried pretty much every combo between 100% and 145% and .988mv and 1175mv. No matter what I can't top +58mhz
Also, even with the power target set to 140% the power % in Precision and GPU-Z never goes over 100. I've seen people in this thread with screenshots of their power % upwards of 113%.
Does anyone have any idea what might be going on here? Is this card maxed out? Am I doing something wrong?

Yea, sounds like you have a dud.

Yeah, that's what I'm thinking. I went through the thread on EVGA where 670 FTW owners posted their stock max boost. I averaged all the verified ones (over 30 different clocks) and the average was around 1190-1200. Many being able to push far beyond that when OCing.

Try the BIOS mod that's been going around. You might be able to hit better clocks with some extra voltage.

If I am hitting 1185mhz stock boost and 1228mhz OC'd boost max is that good or bad?

Time for RMA or deal with it?

I'm using stock bios for 4gb galaxy gc 670.. I saw another thread with the same low OC issue.

Do you guys OC with the beta driver or latest stable release?

Not sure if srs. Be happy with your overclock. I wasn't even able to hit 1200 MHz before volt modding. And don't ever RMA just because your GPU can't overclock that well. RMA only when your card is actually faulty.

And I OC'd with the beta drivers.

I'm thinking about giving that a go. Not sure yet.

On your card, what does the power % go to in precision?

Mine will always max at 100% but will NEVER go over even with the power target set to 145%. Not sure if that's normal or not.

so 1228 is good??

That is pretty weird. Mine doesn't really go above 106% or something like that. With the old BIOS, mine went to around 130% occasionally on Skyrim. I would think that's pretty good if your card doesn't have to go over 100%.

1228 MHz isn't impressive, but it's better than mine. And it's better or about the same level as a GTX 680 reference. Keep things in perspective.

And...you serious? Three FPS matters that much to you? lol
