The GTX580 overclocking thread.
 

Anyone able to get their GTX580 to 900mhz+?

I'm having serious issues with it, even at 1.138v, I can't get 900mhz or higher stable. Maybe I just got a bad one.

Post your overclocking experiences.

I'm workin' on ~ 928/4666. I think the 100% sweet spot is within 25 mhz of the core or the memory speed I'm at.

I wish I could get that high, I can't even get 875mhz stable.

Luckily thanks to EVGA's lovely warranty, I can probably change that in the future.

One thing i never overclock is video card, but that's just me.

Ditto, the performance gain is never worth it in my experience but to each their own :)

Re: The GTX580 overclocking thread.
 

Some cards like the 460 and 470 have a huge amount of headroom so I think it depends on the card.

This. Both the 5850 and 6850 can come within reach of their bigger brothers simply from oc'ing. :)

Default clocks on all the mid-high range cards seem to be low. The CCC limits you to 775-1100 with a 5850, which is ridiculously low and everyone knows it. Mine will do 850/1200 easy on stock volts and @ 5870 voltage will do 975/1250

Stock speeds are for wussies. :p

I overclock my dishwasher.










(crazy)


BTW, stable at 1.138V, 929/4670. :D

I should downclock to 480 speeds and see how beneficial this speed is over that of a stock 480.

I really didn't think you would be the type to say something like that.

I have so many examples that contradict that statement, but I'll just use a few, using personal experience.

• Overclocking a Geforce 6600 Non Ultra allows it to play Doom 3 @ 1280x1024 instead of 1024x768.
• Overclocking a Geforce 7800 GS allows the user to enjoy 2xAA in UT3 as opposed to 0x.
• Overclocking an HD 3850 gets rid of the too-low minimum framerates when things get really crazy in Lost Planet in DX 10.1 mode with fur on.
• Overclocking an HD 4850 allows you to either turn 2xAA on or turn shadows up to medium @ 1280x720 in Bad Company 2 with all other options at their highest, @ 4x AF, DX10 mode, HBAO on.
• Overclocking an HD 4870 allows for 4xAA, 16xAF in Bad Company 2.
• Overclocking an HD 5830 allows you to move up a whole IQ setting in Metro 2033.
• Overclocking the GTX 580 will most certainly allow me to use DOF with GPU physX on along with the Ultra High IQ setting in Metro 2033.

Overclocking is a lot of fun, it's a fun and sometimes competitive exercise, and yes, it definitely does make games playable when at stock settings they might not be.

is there really a need to post how much you hate overclocking in a thread for overclocking a gpu? Who cares, post your overclocked results or dont post at all.

The three GTX 580s I have overclock to 860/2080 with 1.100V. SLI seems to limit the overall overclock and I like to have them all running at the same speed. I run them at a safe 820/2060 1.05V for 24/7 use. The cards are much much quieter than the three GTX 480s I had before.
