Here is a modified BIOS for the GB GTX 670 OC. 1.21v + no throttling at 70c+. http://www.mvktech.net/components/com_joomlaboard/uploaded/files/GB_670_X3_VMOD.zip

Keep in mind that you might need to use a - core offset since core clock is high with the modded BIOS. TY tecfreak @ mvktech.

Sorry for this noob question. Can I use Gigabyte's software to backup and then flash this bios or do I need to use something else? If so what and where do I find it?

Asking in this thread to see if someone else is getting this too

My Kepler Boost is behaving in a weird manner, at stock clocks, I have a KB of 91 (1150 total), but when overclocking I noticed that the max boost doesn't change till certain points, and in some cases, it even increases/decreases, It goes 1200(+50) - 1202(+55) - 1215(+60) - 1227(+72) - 1230(+80).

Now, the weirdest part is, there is no apparent improvement between them, as in, I get the same performance with +60 offset than with +70

This is the result with +60 offset:

http://3dmark.com/3dm11/4034242

This with +70:

http://3dmark.com/3dm11/4034295

And lastly a run with +80 offset (not fully stable):

http://3dmark.com/3dm11/4034968


So in the end, is fine tuning an overclock pointless? or is there something wrong with my card?

Icarian, yes that's totally normal. These cards have 'straps' (or steps) of varying values (although the largest strap will be 13MHz)... not every clock speed value is attainable like it was on Fermi. It's not the first time in nV history cards had these straps ... all the 200 series cards for example also had straps. If you set a clock value that's not achievable, the card will usually fall back to the next lower clock that is.

A change from, say 1202 to 1215 is only about 1%, which would typically mean about a .7% fps improvement. .7% is within the margin of error on pretty much any benchmark out there. I bet if you ran it 10x at each clock you'd find a very slight gain on average from that extra 13MHz on the GPU portion of the test.

That was a nice piece of information, thanks very much, It's my first Nvidia card since the 8xxx's so it changed quite a bit and it left me wondering why it was doing that.

Yup, I installed the f12 bios because I was currently on f11. Anyway, flash went fine and I actually picked up +10 on the core when overclocking. No issues so far.
post #1430 of 1506

Ok I am going to be flashing my bios for the first time ever now

 

I downloaded and installed the vga@Bios program

 

I am running the program as we speak.

 

my bios version is F1 so i am suppose to install F4

 

I installed the F4 bios which is an exe file.

 

Now what do i do from this point on?


Edit : Nevernmind just did it

 

Extremely easy thanks to the Vga@Bios utility.

 

I updated it to F4. So far no difference.
