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.

Hmm. That's what I did with mine, and it didn't change anything with the power except letting the slider go to 150% instead of 132%, so that's probably not it. Sounds like what was happening with the Titan cards though, strange throttling at low power limits - what driver version are you using? There was some speculation that the newest beta versions messed with the throttle behavior.

Someone else will have to answer the other questions - I know you can set the max boost but I'm not positive how to do it in practice.

I know you can set the offset, but nothing shows what the actual mem volt is .. GPU-Z, AB, Precision?

Regarding the throttling with the PE, the only few examples I still remember were fixed by using another cards vBIOS which fixed it. But there's plenty of PE owners so hopefully 1 can confirm if that's old now and there's a "fix" (assumed you've done it right).

The MSI PE cards, I think, could increase the memory voltage as part of their triple voltage overclock feature, but none of the other cards have memory voltage control that I've ever seen.

That maybe the case, but I can increase my memory overclock much further now and it's stable. smile.gif

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 ?

Can't be possible. I wouldn't even be able to finish a 3DMark11 run at +250 memory but with +240 memory it would be fine. Now I'm doing 3DMark11 runs @ +500 memory. On top of that, for some reason my overclocks have been so finicky with Black Ops II. Clocks that run fine in Far Cry 3 and Crysis 3 are still too much for Black Ops II. Would always end up crashing. Normally I would only be able to clock my card at +65 and +200 for Black Ops II to avoid a crash. Now I'm playing at +80 and +400 and it hasn't crashed yet.

So I find it hard to believe that the Bios Flash didn't do anything, considering I can overclock my card further both on the core and on the memory.

EDIT: Is there a bios out there that also increases the memory voltage too though?

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?

Many (almost all) 670 PE cars has this issue. There is only one solution at the moment, being a modified galaxy bios. This bios has working voltage, memory and aux voltage, but voltage reading is broken, as well as the stock fan profile (you will have to make your own custom fan profile)

I just flashed my Asus gtx680 Top Editon, and everything is working fine so far ( i used bios from topic starter and the first flashgiude)

I did not change my 'old' settings in msi afterburner, and now it is automaticly on 1397mhz when i run furmark (before 1319mhz with boost)
is that normal?
Srry if it is a noob question redface.gif

Till i get my gpu bracket from Dwood, and my antec 620 watercooler is just clock it back a bit.

That is completely normal. Higher voltage gives a higher core clock speed. That is why it is recommended in the original post to reset your overclocking settings, prior to flashing.

@ tinuz97 if you set your voltage higher your card boosts higer so 6 13mhz steps are normal

does anyone know a way i can fix my voltage at boost voltage???????? just a month or two ago it was possible with tools like precision x but since driver 314.XX i can only set the voltage 0.025V below maximum boost voltage, i can't controll this last part and as soon as the gpu load drops below 60% the voltage drops down from maximum boost voltage but the clock stays at maximum. in result my card becomes unstable with overclocking profiles that worked just fine month ago

Did you guys with 670 PE try increasing DEF value ?
And it doesnt help at all ???
Because you need to increase DEF value so high that your card never reeches 100% power usage
Are you telling me cards throttle before reaching 100% usage ???

Does not work, already told you this way back.

Hey guys. I got a set of MSi 660ti's in the lovely island of Barbados. Our ambient temps are around 28C during the day. I've tried to mod my own bios, and generally once I've modded one of them, I use it on both cards. Problem though I'm getting is that I'm not seeing any improvements on the overclocks. Only thing I seem to get is slightly more heat. Max temp gets around 77C on top card in Heaven. Can someone mod this bios for me? I've got a feeling I'm doing something wrong. One card is a great overclocker, gets 1300+, other gets 1241. Both do about +500 on the mem.
