Hi, just bought a GTX 560 Ti, and I was wondering what everyone got theirs to OC to. It seems like mine doesn't like anything other than the default voltage. The moment I change the voltage I get display driver crashes. What voltages worked for you?

I manage to do a 950/2100 OC stable for 2 hours of kombuster stress test at stock voltage.
 
950/2200 seems to be the best mine can do without bumping up the voltage. I've tried some mild voltage bumps but was never able to get it stable so I just leave it.
 
I'd like to know the same thing but about a GTX 570, lol.

I've only stuck with a "safe" OC @ 800 MHz for now but I wonder how far I can push them.
 
Yeah I'd like to know everyones specs on tehir OC'd 560Ti's COMON PEEPS! Lets make a thread!! (It would save me time, trial, and erroring hehe)

At the moment I run my 560Ti @ 980Mhz Core. I think the MV's is like @ 975mv stock ---> I increase that to 1050mvolts to maximize stability (could be 1150 can't recal off the top of my head...I'll have to double check sometime). I need to tweak it more. I just haven't been able to put in the time to get the settings optimal. I did run the MV maxed through MSI afterburner CD that came with my card or I downloaded it...can't remember..., and it ran 1GHz stable in Metro 2033 (Metro 2033 is the game that stresses my graphics system the most so I like running it), thing is when I took a break after 30 minutes to check sensors my GPU temp was up to 91-93 degrees :eek: so I decided to drop it down some. lol. Now its like 67-71 with the fans on auto, I find it good that MSI lets you tweek stuff but wow 90+ seems like it could ruin a card or at least it's way to hot. maybe that setting is for like people with watercooling blocks, dunno. Anyhow if I run some valve games @ 1GHZ core temps go to low' 70's so most likely it uses the DX9 engine and just doesn't really stress the card in those low graphics quality type games. but DX11 game like Metro really heats up an OC'd card. 1 GHz on those Valve games really does provide a noticable speed increase. So 1GHz is definitely worth aiming for IMHO, my card came stock at 880MHz btw.

I need to tweak memory bandwidth, I haven't really done Videocard OC'ing before so this Kombuster is like the best at checking Videocard stability? I'll have to try it...

Yeah I need to find out what's the average memory OC speeds as well. Stock is like 2200 on my card I believe. I wonder how high people have gotten stable. 2300 or 2400 or more??

950MHz on the core I would think should be standard/easy, especially if you can raise the MV on the card by 10 percent like MSI ones, dunno if they all can.... My MSI does well which is why I purchased from them I like to support company's that really put out GREAT products, and OC'ing is exciting when your as nerdy as I am lmao.

Now I'm going to google memory speed OC's on 560Ti's :p (MOAR performance!)
 
EVGA 560ti 2gig 384 shader version here. Stock clocks are 823/1645/2004

Been using it at 975/1950/2200 with 1.075v. Using Evga's precision oc'ing software. Max core temp is around 65-70c depending on ambient, fan at about 80ish % duty cycle.

Stability testing via multiple futuremark 11 runs and gaming. Like the card, really want to find another for a decent price to SLI.
 
Dang, looks like you got a good one. I can't do anything to my voltage at all. SUCKS!
 
using 285.62 driver here. What program are you using to oc? Lotta folks like MSI afterburner....I havent used it myself. EVGA program seems to do mostly everything I need. Would be nice to change vram voltages, but im not sure if thats a design limitation or what.

I use MSI afterburner and I'm on 285.62 drivers too. I just noticed now too that my video card crashes when playing starcraft under the overclock setting yet passes Kombuster for 3 hours ...
 
28x.xx broke a lot of 5xx cards. Upgrade to 29x.xx and you'll see stability increase while the need for voltage to reach certain clocks decrease. I have a Galaxy 560ti and under 28x.xx needed 1.062 @ 925MHz to be BF3 stable but only 1.050 to be Kombustor stable, and even if I ran at stock the driver would crash regularly. NV actually sent out a request for people to send their cards (on NVs dime) to their Santa Clara facility for testing because they were having difficulty recreating the issues in-house. 290.xx fixed a majority of the issues with only the occaisonal crash, and the brand newest 295 driver has been flawless for me. Now happily at 950MHz @ 1.050.

I've been running the 285.79 driver for my 560ti SLI setup and have been able to reach 975mhz. I've heard mixed reviews on the 290.xx versions but maybe I'll give them a try. Here's been my highest 3DMark11 score so far (going for 10k):

Switched to the 295.51 driver, bumped the core to 1000. Requires 1.125v however. Will run 3d mark (5300 on the graphics score), and Batman Arkham City benches without a crash. Crashed playing Saints Row 3 but that was with 1.1v....no crash since the extra .025 yet. Not 100% convinced it stable quite yet.

Core temp is 70-75c. Totally stock cooler, closed case...have one extra 120mm blowing down over the card as well. Fan getting to 85%+ speed....lol that sucker is pretty loud at that speed. Not as bad as the 8800GTX im benching in another rig...but still... really makes the computer sound like its working for its money!

Have yet to try and stretch the memory OC

quite the change from the GTX 275 and 285 cards I was using that have been donated to friends...man those things oc'd like ass... but with no voltage control, what can you expect I guess.

Oh, and I guess I need to switch to MSI afterburner...as the EVGA program core clock graph stops at 1ghz....haha
