EVGA GeForce GTX 560 SC (non-Ti) overclocking & volt

[technoatom]

Hello there. I have an EVGA GTX 560 GPU I'm overclocking and I was wondering if anyone here knows what the max safe volt is for this thing? I've done some Google searches and I saw a few people say that 1.075v is what they use. My default volt was 1.050v and I have increased it 2 notches to what those people did. So far everything seems to be fine.

Any helpful information would be greatly appreciated! It's kind of hard to find info on this subject regarding my particular GPU for some reason. I don't know why.

Edit: My original OC was apparently unstable at both default and 1.075 voltages. I have no idea how Legitreview claimed they achieved 950/1900 and 2355 on Core/Shader/Memory clocks at stock voltage. I was only able to achieve 950/1900/2170 so far and that's with bumping my voltage up two notches. I am using MSI Afterburner and I found out MSI won't allow me to go beyond a specified safe limit coded into my GPU bios. Which is nice! Any more tips guys?

By unstable I mean an artifact was detected with EVGA OC Scanner and not real world gaming sessions. During game sessions those clocks are fine as are the temps. But I want 0 artifacts.


Moving this over to the video forum where more responses can be offered.

1.087 Volts, I would assume. The GTX 560 is the same as the 460, and that was the max for it.

Thank you for the prompt reply. I'll see what a few other people say and go with the majority. Thank you again!

So far everything seems to be fine. I have my EVGA OC Scanner running a stress test and at 8 minutes my temps are perfectly fine and no artifacts as of yet...

GPU info:

EVGA GTX 560 SC (my custom clocks)

960 mhz Core Clock
1920 mhz Shader Clock
2355 mhz memory clock
Voltage: 1.075v
Fan Spd: 100% 67c (after 10 minutes of stress testing)

Id assume 1.087, since it uses the same GPU as the GTX 460. Also youre stock voltage is really high. My GTX 470 has a stock voltage of .925.

Thanks for the reply. I'll look into my stock voltage again to make sure I didn't misread it. Perhaps it's higher than average because it's a factory OC GPU?

I wouldn't go any higher than 1.05v. That's what I use for my 870/1740/4100 overclock on my GTX 460s. Too much heat at 1.087v.

After stress testing last night I found out that my original OC was getting artifact when tested at high resolution @ fullscreen on Max Load. Temps were ok though. Here's my current stable OC after a 45 minute load.


950 Core
1900 shader
2170 Memory clock

Volt - 1.075

As a reference Legitreview said they achieved 950/1900 and 2355 on the memory on stock voltage. I'm not sure how they managed that.
