From what I have read so far most user of PE get throttling around 105-107 range even though the slider is higher . (that is if you didn't edit 100% power values in bios , cause those % numbers are based off default 100% ).

Ok, what clock speed is this , offset core +40 i don't know with unlocked bios .

If you see that when you get to power % of 105-107 the clock drops its a power management issue (not much you can do AFAIK right now ) .

Only thing is to find sweet spot, the very lowest voltage added with highest clock before it throttles .You can let it throttle a little I guess but if your seeing big drops then I would cut back clock/voltage .

I have been looking around the net and I have noticed that apparently in early production line of the MSI GTX 660 TI Power Edition use to overclock like a beast but when NVIDIA cracked it they had to change the BIOS settings to restrict it. That being said I just realized, Why doesn't anyone who Pre-Ordered or got the cards early on upload there BIOS so those locked out can achieve what we originality paid for? wheee.gif

I don't beleive that at all , all bios are same and if you look at reviews, they all use AB 2.2.3 which is only version that works with voltage .
Most got 100mhz + on these cards with slider maxed .

Nividia stopped MSI from adding voltage control over newer versions of AB . thats only way they can stop the way MSI does voltage control as the cards were already made, there no change in hardware .

you can check his results and bios version here shown in GPU-Z . Mine is 16 version but see what yours is ,anyway if you can get high 1200-1300 that is good .

Also later drivers tend to hinder OC a bit IMO past 310 versions(above this version I seemed to lost 13mhz , had to lower for same stability ) .

AFAIK, all cards have 1.175v bios but that doesn't stop going higher with PE versions or lightening .

How high do you want to go ?
you want card to last few yrs or you just want high clocks for BM, if you want 24/7 gaming then IMO PE don't need to be unlocked as you already can go higher than unlocked cards for other makes .

Edit: there was a lot of misinformation with these cards when they came out. because of know 1.175 lock down and AB didn't have triple voltage control when release many thought the over-voltage was just a market ploy and no added voltage was available . This changed with 2.2.3 and as long as you use it or latest 3.0beta you have voltage control like all reviews got .

For a non-MSI card (mine is a reference PNY), would it still make sense to use Afterburner 2.2.3 after unlocking and maxing out voltage through the BIOS, or am I ok using any latest Afterburner version? I'm using 2.3.1 right now.

I won't matter either one is fine as your not using voltage control of triple voltage control of MSI's feature .

Stay with latest .

I didn't bring this up but user of MSI PE 660ti PE can use latest AB and get full voltage control if you don't want to use 2.2.3 or the 3.0 beta's .

Just add these lines to your config file in the profile subfolder , under settings .

profiles subfolder,config file Ven_10.............



add these lines in settings
[Settings]
VDDC_Generic_Detection = 0
VDDC_uP6262_Detection = 4:30h
VDDC_uP6262_R1 = 1000

Ha... new observation. I confirmed my power % slider doesn't work. Whatever I set it to, even at stock clocks, my card throttles at exactly 99-100% point. And it throttles really badly. This may be the reason of all of my problems. One step closer to RMA. Contacted MSI support today - will keep You all posted.

Not sure what they can do other then release new bios . It seems to affect all PE versions 660ti, 670 etc .

Since a edited bois of another make seems to fix it , it would seem its all in bios and not hardware related .

The highest I have seen so far is mid 90's and that is FC3 , that gives me highest power % , higher than Heven or Valley .

But I don't max out clocks/voltage . I run 1241@20mv+ (I can pass in valley with 1267-1280mhz for same voltage ) , FC3 is most demanding and buggy IMO so 20mv is for safety net .

is the evga gtx 660 2gb sc (non TI) silent ? i want to know if to go wit d MSI twin frozr 3 or the evga SC edition
post #1939 of 3662
Reference fans are usually not silent. Some are buzzy even at low RPM. Silent is always a relative term, because I've seen some youtube videos of people calling their really loud fans "silent" because they can't hear them over the roar of other components in their cases.

Yeaaaaaaaaaaaaah - my problems are FIXED!

Due to the fact that I discovered throttling at 100% I decided to check which apps get to 100% on stock and which apps don't. Result: 100% on stock clocks happens only in 3dmark11 (even heaven 4.0 has 70-80%)

Than I overclocked my GPU to +50Mv and 1333 MHz KB clock 7000 memory

Checked again - 100% in some games, caused throttling.

I decreased voltage to +40Mv (so it's 1,175+0,040=1,215v) and declocked to 1320 MHz on core.

And checked again - none of my games goes over 95%.

And You know what happened? With Adaptive Vsync On - 70-90% GPU usage. With Adaptive vsync Off 80-99% depending on game.

My performance is well.... AWESOME. smile.gif

Thank You all for help smile.gif Especially Edkiefer - Your advices leaded me to this wink.gif
