Want to get more out of my 580

post #1 of 10
Thread Starter 
So as the title states , i wanna get more out of my EVGA GTX 580 SC, at my resolution it doesn't really call for it, but hey when you drop 500+ on something you wanna get the most out of your card, or i do anyway.

And besides, since my CPU overclocking is pretty much done, i have that itch to bench!

I was able to do an extremely modest OC below, using EVGA Precision

-core clock-802
-shader clock-1599
-memory clock-2030

I want to see how far i can push the card with stock volts, i want to stay at stock voltage. Although i noticed when using EVGA precision when i bumped the core clock up another 5 when i clicked apply it reverts back down to 802, everything else is able to be applied but the 807 core clock reverts.

I am guessing i should go with MSI afterburner and scrap EVGA Precision?
Either way , those of you who are familiar with OCing this card your input would be greatly appreciated, like i said, i just wanna push the card as far as i can without upping the voltage.

EDIT: Probably should have mentioned my res, 1920x1200, the card Handles EVERYTHING at max settings flawlessly with the exception of Metro of course, although i play it on max settings and it is very playable

Your going to have to up the voltage for a decent overclock that will accually give you noticable performance increases.
post #5 of 10
Definetly go with MSI Afterburner, it's awesome.

As for the overclock I am able to go as high as 875/2100 on stock voltages and a lot higher if I increase the voltage (I am using the ASUS version of the card, but doubt it would affect that much). Just like the other guy I really do love this card, the only downside so far is that the drivers crash every once in a while and resets the OC until reboot, rather annoying. :/

(just as a little outside comment to the above poster; I don't know if it's me, but I notice a rather huge differences in performance between, say 820 core and 875 core, both on stock voltages. ;o)

Well as for now since i am extremely new at GPU OCing i wanna stick to stock volts for now

I downloaded MSI afterburner, so the premise is the same as CPU OCing right? Raise the settings until unstable , in the form of artifacts?

EDIT: I am also wondering if GPU temp is the only thing is is able to be monitored ingame? can you force other things to be monitored ? It only seems i can view the gpu temp so far. Is there a way to see more things such as cpu load and temp ingame? Or even GPU load in game ?

EDIT: Well i am guessing i would have to use riva tuner in order to minotr things like GPU usage and CPU usage, alas i am not able to find in MSI afterburner where you can view these in game.

Get it under water. 1Ghz OCs are achievable with additional voltage

My default voltage is 1.0872v. I found out that default voltage can vary from GPU to GPU. I was always wondering why other people would get lower temps than me at stock core default voltage. I currently lowered mine to 1.0750v which brought down my temps by 1C and still run stable.

Here are some of my 580 SC 1.0782v clocks to help you. Those specs are GPU-Z clocks.

The GTX 580 SC is 3% gain higher than a GTX 580 vanilla at stock speeds.

39-40C idle @ stock 797Mhz core on SC which is a 3% gain over vanilla stock.

40-41C idle @ 838Mhz core on SC which is 8% gain over vanilla stock. 838 Core/1061 Memory/1676 Shader

41-42C idle @ 855Mhz core on SC which is 10% gain over vanilla stock. 855/1086/1710

42-43C idle @ 875Mhz core on SC which is 13% gain over vanilla stock. 875/1111/1750

43-44C idle @ 890Mhz core on SC which is 15% gain over vanilla stock. 890/1135/1780

To go higher stable I have to bump my GPU to 1.1000 voltage.

44-46C idle @912Mhz core on SC which is 17% gain over vanilla stock.

Now when I OC I bump up across the board for Core / Memory / Shader to be exactly the same percentage gain on each GPU-Z validation clocks.

I got clocked to on my final score 3D Mark 11 mid level performance score of 6902. On an i7 950 @ 3.8Ghz OC - GPU 1.1000 voltage @ 912Mhz core.
3D Mark 11 score of 6902.

I won't bump voltage any higher as I don't feel comfortable and newer to over clocking.

I have mine set to 1.0750v 875/1111/1750 and 24/7. For some reason memory clocks in Afterburner or Precision are higher example is Precision shows shader at 2220 but it reads as 1750 in GPU-Z. Keep this in mind I got my readings from GPU-Z to validate how high of a percentage I was getting from my OC.

Hope my homewoked helps you out bud.

K got my OSD working with afterburner, no need for rivatuner.
Currently afterburner shows my gpu voltage at .962 working my way up in increments of 5 on the core clock with shader clock linked. So far i am at

cc-827
sc-1654
mc-2055

Have been testing by just play BFBC2 since the game is constantly at 99% usage, not witnessed any artifacting yet, although as per your info Arizonian i still possibly have quite a way to go !

On another note, since the stock cooler on this guy is extremely loud and i wont be going water on this rig , looking at adding this aftermarket cooler on the card http://www.arctic.ac/en/p/cooling/vg...us.html?c=2182 anyone have any thoughts on it ?
