Is that true for the new ones, or only the ones with the EVBOT port?

All they did was to remove the PORT.

I bought 200 ports through Ebay for about 20 USD - Took a soldering iron and soldered the port on. Took 2 minutes tops, even a child can do it (Or at least someone who read a basic soldering guide on the internet). After that you got full access via EVBOT.

Did it to all 4 of my cards - 10 minute job, and that is with the soldering iron heating up.

179W DEF and 250W MAX = 140%
225W DEF and 250W MAX = 111%
248W DEF and 250W MAX = 100%
Differents % but they have the same MAX TDP...

You can check you TDP with Precision X on the POWER Graphic. I don't think that you need a lot of that.

If you don't want throttle, set your BASE CLOCK, to your maximum stable OC. P2 is the BASE Voltage, you probably need to increase it then. Default TDP as well...

Yes 2.3V is the maximum Voltage, but if you don't have a PCB with some Power Phases, it could be damage like burned VRM.
I've got 10 PP, (8 GPU + 2 RAM) on my ASUS 680. The reference 680 PCB got 6 PP (4GPU + 2 RAM).

Will give it a try. Maximum overclock I can get for benching runs at 1.215V is 1358MHz but it's only just stable in 3DMark Firestrike and crashes the other 3DMark tests.

I'm pretty sure by me increasing the voltage, it will allow me to push any clock further whether it be memory or core. Don't see what you seem to be misunderstanding. There isn't two separate voltage controls on this card (at least not by what I am able to change) and regardless of the fact of whether or not what you are saying is true (there is a separate memory and core voltage), all I had to do was adjust the one I know of and I'm very able to increase my memory clocks much further. The clocks are stable in 3DMark11 and Heaven Benchmark; so far with what I tested a couple of hours of Black Ops 2 as well.

Forceman has explained it pretty well already, but no, increasing the core voltage will not allow you push any clock further, it will only allow you to push core clock further, and yes of course there IS separate memory and core voltage.

There is no "THE VOLTAGE" as you think, what is increased by modifing the bios is CORE voltage, not some universal THE voltage smile.gif

Memory and core doesnt even work on the same voltage.

What is happening exactly with your card I am not sure, but it is posible that memory is as much unstable at +500 as it was before, you just havent tested it properly yet.

Where exactly did it crash first time before you modified the bios and after how much time exactly ?

I finally decided to use kgb to unlock my bios. I was able to overvolt my 670 pe before unlocking my bios. There are some benefits with the unlocking though. Temps are lower at 1.212 volts with the unlock. I had to set -52 core offset to be stable at 1254mhz. One problem that I continue to have though is once I hit 100-102% tdp I throttle a lot. Dropping down to 1200 or lower even at times during benchmarking. With the unlock max powerlimit is 150% but it seems like that slider is being ignored.


Anyone have any ideas?

AFAIK that's normal PE behaviour with this, it doesn't really work 100% (ie: the problem you see).

BTW: does AB or Precision show mem volts for your card?

I'm using msi 2.2.3 and I can change the memory and aux voltage if i want. Don't know if they actually work though. As far as monitoring memory voltage that's not possible for me.

So is there no way around the throttle issue?

When you unlocked it did you mess with the power settings? If so the 100% you see now may actually be what used to be 115% (or whatever) and so the card is hardware power throttling. That's all I can think of. I'm not positive the power limit scale changes like that, but my undertanding is that you can change both the power limit (the maximum setting in Afterburner) and also the "default" power limit.

Didn't change anything. Just unlocked with kgb command in command prompt. It unlocked then flashed the card.

Should I change the default power limit and how would I do that? If I can do that what would be a safe power limit for my 670 pe card? Also how can I change the max boost limit since 1306 is not stable? I have to use - offset.
