You are at 1241 according to your screenshot, which is an okay overclock. That's probably just as high as your chip can go.

1241 is actually very good considering the base clock is only 905 or so for those chips.

Crashes in Heaven



Hraven set at 3560*1440, 8X and Ultra

110 Mhz score was 1086

i can do 1241mhz on my gb wf3 but i cant stress it heavily, it WILL crash. 1228mhz seems to be 99% stable. i know it'll crash i just dont know when it will.(no it hasnt crashed yet but my luck on this card says it will)
and as subseven said, thats a good clock at 1241.

Ever card I have had has always had extremely low temps(I have a side and bottom fan for the GPU) my 560ti was always under 60C and now my 670 is under 50C under full load.

I am wondering what damage I can do by increasing my voltage even more than 1.212v should I go until my temps are at the standard 70C? I messed 3570k by reading temps of AI suite and do not want to make that mistake again.

Should I flash my bios to 1.5v or something as long as my temps are under 70C?


This is my max stable overclock.
gigabyte 3x 670
at 1267(1275 +8 in afterburner)
1800
105% power at 1.212 volts



After a fully maxed(1080p) heaven 4.0 run in which I got 35.7fps

1.21V is the maximum limit of overvolting through BIOS modification. You can go past 1.21V only if you do a hardware modification.

So why would anyone do watercooling for the 600 series? Also ty for your help and are my temps strange for air?
post #2347 of 3357
To keep the cards from temp throttling, and to control the noise. Otherwise not a lot of advantage in water cooling them.

As long as your temps don't reach 70C then you're good. For me, I really needed to watercool my GPU because my ambient temp is 33C (living in a tropical country).

There's a lot more to it than just that. For starters, my two 670 FTWs would squeal like banshees playing games like Far Cry 3. The noise drop was more than just a little. Also, the "stay under 70 and you'll be fine, there's no additional benefit isn't true. My 1254 OC on my top card is only stable under 40c, then I start getting screen glitches. Running at 30c I can run Heaven all day.

Just like with anything, core temps affect max clock speeds. To what degree varies from chip to chip, CPU to GPU etc, but cooler chips run stronger and last longer. This is why we water cool.

I got my evga 670 ftw to 104-520 with this guide. Thanks for the info. +rep
