***OFFICIAL GTX 770 OVERCLOCKING THREAD***

[MoRT489]

Haven't seen one of these on the forums and have just started trying to clock my MSI Gaming edition using MSI AB

Gone straight in at:

Core Voltage: +0mV
Power Limit: 111% (max)
Temp Limit: 94ºC (max)
Core: +141 (1200MHz)
Memory: +195 (1850MHz)

Been playing BF3 fine for the last 2 hours max temp 65ºC, GPU usage at around 80% (held back by my Q9550 probably - although that is running @4GHz and isn't showing max usage on all cores, so I'm not entirely sure).

What overclocks are people getting with their GTX 770s?

Managed to push it a bit further to 1296MHz core on boost but the display driver crashed after about 30 mins gaming. Not even tried upping voltage yet so looks like I got a good clocker compared to some of the review samples

Come on 770 owners, whack up ur clocks!

Wow nice! If it will go almost an extra 100MHz for benching u must be able to get it somewhere in the middle for 24/7 I would have thought.

Hopefully RetrogamerX will pop into this thread with his SLI 770 lightnings!

What ceiling are you talking about?

 

[MoRT489]

Good choice I got my core up to +160, higher than that and I was getting "display driver stopped responding" and "DirectX freezes". I need to try to get the memory above 200 next.

I would recommend setting a custom fan profile, on BF3 on the auto mode I get up to 74°C but with a custom fan profile on a curve with 75% fan speed at 70°C temps drop to 64°C and it's only slightly noisy (would not notice it at all with headphones on). This is in a case with poor air circulation and also not particularly hot here at the moment.

So how are people doing with their 770s now that we finally have a fully-working driver from nvidia?

 

[MoRT489]

The limit on my core seems to be +155MHz (1214MHz pre-boost, [TBC] boosted) but adding Core Voltage seems to make no difference I've got the memory to +250MHz (1905MHz) but still testing to go higher.
