Gigabyte GTX 670 OC Version *HANDS ON* - Page 139

Been using mine for a while now and the clocks I got for my O/C's were Core 1310 & Mem 6703.

Funny thing is I have had to make a profile for a lot of older games and make it so Power adaptive mode is set for Maximum performance, it's a bit annoying when your playing something and it flicks down to 324 core & mem speed even though fames are at 60fps it acts all weird like a jitter affect.

Also shot of it in my case probably the best card I have ever bought, up there with the 8800 GTS 320mb when it was new.

So I just had a pretty scary moment lastnight. Stoopid me decided load the F4 BIOS for the GPU. It installed but I didn't have any stability. Since I backed up my original BIOS (F1), I reinstalled that but my stability was not where it used to me. I sorta ignored it until lastnight when turned on the rig and after getting the Win7 splash screen I got no video output. Seeing video in Windows Safe Mode, I figured it was a corrupt driver. Even after I install a WHQL driver, I still wasn't seeing video. I then realized the issue. If anyone is going to install the BIOS update, this is what you will need to do to ensure stability:

1) Using the Gigabyte VGA @BIOS tool, check your currently installed BIOS version.
2) Backup your GPU BIOS using the tool
3) Go to Gigabyte's site and DL the appropriate updated BIOS matching your BIOS series
4) Uninstall PhysX driver and your Riva-type tuner tool.
5) Reboot into Safe Mode
6) Uninstall all other nV associated drivers
7) Reboot into normal windows. At this time you should only have the standard Windows VGA driver installed.
8) Using VGA @BIOS, load and flash using the new BIOS that you DLed.
9) Reboot
10) Install your nV drivers of choice
11) Reboot and install your tuner tool and test.

For the guys who have lower core clocks, maybe you can give this a whirl and see if you get any improvement. BTW, my ASIC score is exactly 100%.

For the record, it seemed that the temps I was getting with the newer BIOS (F4) was actually hotter than my original BIOS (F1) and this was after I used my current fan curve. Also, it seemed to me that I got less stability as well. I went back to my original F1 BIOS and I can still score 52fps on Heaven with everything maxed at 1080p. In this testing, I didn't try 3DMark11 since I was crapping out at my current benchmark settings.

As an aside, I can no longer hit 1280 core clock stable anymore. I use 1275 but still yield the same original max fps that I did when I was able to run 1280. It MIGHT be driver related but I haven't spent the time yet to test that theory.

Sorry for the delayed response.

First and foremost, you have nothing to worry about. just because the card isn't sweat that doesn't mean something is wrong. When I run Heaven 3.0 with max settings at 1080p, the card doesn't clear 70%, IIRC.

I am not sure where in the Skyrim settings where you can turn on vsync. Check there first. However in nV CP you can turn it on either globally or application specific. In the nVCP, go to "Manage 3D settings" on the left. Then on the right you will see two tabs: Global Setting and Application Settings (I think, not at my computer now). If you click on the Application tab, you should see all your installed games. If you don't then you can add it.

In either location, Global Settings or Application Settings, you can change the setting the Adaptive. Remember though that if you change in the global settings area, you should go to all your games and turn off v-sync in the games. If you don't, then you will experience weird stuttering.

I hope this helps.

Thanks for taking the time to respond! I found the options to change vsync. I'm happy the card doesn't need to use all of its power to run the game. Less power I'm hoping.

I have a sweet total stable core clock of 1161 (that's the max freq. including the Kepler boost). Short stick of the draw, only runs Heaven for 10-15 min before crashing on anything higher than that.

Got a Gigabyte GTX 670 a few days ago which I will overclock once I get my CPU fully stable.

I noticed in reviews some cards have higher boost frequency than others, is this an indicator of how well the card will overclock? mine has a max boost of 1150Mhz, which seems kind of low.

Mine 1168 before OC. I'd say it's average stock boost.

Does it have a correlation with how well it'll overclock though? or it doesn't have anything to do?

That's what I'm trying to determine on this thread. Might want to check it out, and also you may want to read the first link in my sig

Anyone using our Gigabyte 670 with a 1440p monitor? Can i get some feedback?

 

I currently ordered a Yamakasi Catleap and will be gaming in 1440p from now on. I just want to know if I need to add a second GPU? or maybe sell this card and get 2 670 4gb ones?

 

Thank you.
