Hey there TH :)

I recently tried to OC my GPU with afterburner but found it a little too complicated for me at this time - so i decided to use the gaming app from MSI to do it. I primarly do this to learn more stuff about my hardware and want a second look on the results

Here is my card;
http://www.msi.com/product/vga/N770-TF-2GD5OC.html#hero-overview

I get three diffrent settings i can use such as:

Silient: 1150 mhz (allmost all time)
Gaming: 1188-1190 mhz
OC mode: 1250 - 1260 mhz (max temp is 75 degrees in "the valley" benchmark - extream HD)

Is that too "high" for my card or is it fine :)? Hope you can give me a hint!
 
Will depend on case cooling, ambient temp and such but MSI has the best cooling system in the 7xx series.

Pick one, run Furmark, observe temps.

As for a starting point to do it manually.....

http://www.guru3d.com/articles_pages/msi_geforce_gtx_770_gaming_review,23.html

We applied this as a profile:

Power Target 111% (priority)
Temp Target 95 Degrees C
CPU clock +25 MHz
Mem clock +350 MHz
GPU Voltage Memory +12 Mv
Fan RPM, default

Some users have reported that while using the gaming app, their card was OC'd all the time even at idle. I have never used it so can't advise..... I use Afterbruner.

If you're not noticing any artifacts or other graphics glitches and it's stable then, no, those speeds seem fine. Manually you can push that card much harder and still be safe, as long as you're able to cool it. I wouldn't be worried until games start crashing or the video driver randomly stops working.

Tried to do some OC on my own - goood i should just have started to use afterburner... it´s damn easy when you get the hang of it ^^ heres what i got

http://oi62.tinypic.com/34njdw0.jpg

after raising the core clock with +80, the power limit to 111% and the mem clock with 350+ it runs stable at "the vally" extream HD

I get 1267 mHz core clock and 1927 mHz mem clock (dunno if i should go higher - plz let me know if it will change anything) after the OC which i think is fine when the card dosent get a degree over 75 degrees on 100% load

Here is a pic of the bench result http://oi61.tinypic.com/w2ncyf.jpg

Soooo what i need to know now is:

1. can this damage my GPU?
2. can i go higher than 1267 mhz? Seems to be stuck no matter how much i change the core clock (i wont go higher since the temps are just as i like them - but allways good to know ^^).. if i missed anything plz let me know :)!
 
Yes, the Guru3D site kinda takes all the mystery outta AB, but I'm still not used tot he new visual presentation.

Watch Boost clock .... most peeps getting 1500 - 1590 with the MSI ... didn't see any reviewer break 1600 yet.

It's all about temps. Keep GPU temps under 85C....VRAM / VRM should stay under 100C. You'll wanna use Furmark to see max temps.
 
As designs have improved, the electronic parts have steadily improved and are capable of handling much more heat than with older generations.

From the horse's mouth

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-770/specifications

[GTX 770] Thermal and Power Specs:
Maximum GPU Temperature (in C) = 98 C
Graphics Card Power (W) = 230 W
Minimum Recommended System Power (W) = 600 W
Supplementary Power Connectors = One 8-pin and one 6-pin

The other thing that is true now that wasn't "as true" in the past is that, like CPUs, they are much better at protecting themselves and will automatically throttle down if their 'health" is in any way threatened. I don't break 39C on the twin 780s, when given the fans free reign, but by limiting them to 850 rpm, I won't break 44C at 26% OC. I had no concern about temps, I basically would cooled the PC to kill even a hint of a sound coming from the thing.

My son's twin 560 Ti's OTOH are OC'd a bit higher on air and will get well into the mid 80s in summer time, more if I don't nag him to clean his dust filters ... still going strong after 4 years.

But don't just look at GPU temps, thatz a big thing in water cooling..... Many of the popular designs will win the GPU cooling by say 1C and yet by 30C hotter on the VRMs or 12C hotter on the VRAM.

If ya read any of the press releases, interviews or videos on the AMD R9 series, company representatives repeatedly state that the "their designs" are expected to operate at 95C.

I cant messure my VRM/VRAM temps with GPU-Z but since my core is around 75 degrees (1267 mHzclock) i dont suppose its bad :)?.. or tell me a smart way to do it cus i dont want to grill my gpu ^^
