680 Overclocking (Calling all owners!) - Page 103

post #1021 of 1059
Ok, so a quick update. I water cooled my GPU and that seems to have fixed any issues I was having, of course it could have been a conflict with the GTX580 I had installed too. Anyways, so far I have hit 1289Mhz on the core and 3200Mhz on the memory during benching. I will play with it more tomorrow to see if I can squeeze a little more out of it. One thing I will say is that I am a little disappointed that I did not beat my previous HD7970 at 1125Mhz on Vantage.

Also i see alot of people geting high overclocks and everything But what do you guys think is the average stable 24/7 OC? I know it depends on the particular gpu but there has to be an overall standard right?

for me then the difference in games is really noticeable. Playing BF3 with with 1080 on ULTRA and on the high load maps like Gulf of Oman then you can drop to sometimes 50FPS in some places. With the overclock I never go below 60 ... unless a plane crashes into a tank right in my face or soething ... then I get 40 FPS ;-)

deffo worth it

+1 its well worth it to overclock especially the memory as the GTX 680 is bandwidth starved.

so I was just messing around with Nvidia's 3D vision and had it installed and I found that even when it is not enabled and simply installed I get a severe drop in performance. Running the Unigine benchmarking I got a points drop of around 200 from 1450 to 1250 using the same settings from the top 30 thread.

I reinstalled the drivers but this time left out the 3D vision installation and then the score jumped right back up to 1450 or so. Very strange. has anyone else noticed this or does anyone have any guesses at which even when deactivated 3D vision plays silly buggers with GPU performance?

I wish people just stuck to the Heaven Benchmark standards
Extreme everything @ 1080p with AAx8 and AFx16

(unless you have a lower res monitor, then that's totally understandable)

BTW, overclocked my 670 gets 50fps in Heaven smile.gif I've heard some of the 680 Lightning guys getting like 60fps in it!!! 0_0

I try to oc GTX 680 on EVGA precision x, so basically I just increase powertarget to say 120% and hit gpu offset to +115mhz and mem offset to +500 mhz so it would mean that those are my new clock speeds now? What should I change the fan controller is it best to leave it on auto?

its for the Zotac extreme the install is in chineses but its in english. It has a built in Flash/Save bios ability and its great.
SAVE YOUR BIOS FIRST! then select flash bios, ok, then select the file from the OP and wait until its done, reboot and your good ! thumb.gif Super simple.


I used nvflash myself but other guys are saying that this utility from zotac flashes the bios with ease.
post #1029 of 1059
did you see any performance increase after the BIOS flash? Would be interesting to know if this is worth the hassle ...

MSI GTX 680 OC here and i can't get more than +55mhz on the core without getting a driver crash sadly frown.gif
