Overclocking help - MSI Twin Frozr II GTX 560 Ti

post #1 of 8
Thread Starter 
Hello, I recently purchased the MSI Twin Frozr II GTX 560 Ti. It is currently running at stock specs of core clock 880mhz, shader clock 1760mhz, and memory clock 2100mhz.

I'm a first timer when it comes to GPU overclocking. I'm not looking for a crazy OC to max out this card. I'm more looking into a moderate OC where I can maintain low temps without high fan speeds (noise is very important to me). One thing I like right now at stock is that the fans rarely run faster than 40% and I can't hear them at all.

What are some moderate OC specs for this card? Just trying to get a little more out of the card so I'm not looking for crazy numbers here. Hopefully keeping same voltage as well.


TL;DR
What is a moderate OC for the MSI Twin Frozr II GTX 560 Ti without changing voltage?

Try 10mghz increments on stock voltage and run benchmarks after every increase and monitor temps and look for artifacts. I started doing this yesterday with my new GTX 560 Ti Hawk Twin Frozr III which is supposed to easily hit a 1ghz core, it's default is 950.

I believe the shader clock is linked to the core so it will increase as well, but I don't know if it HAS to, I'm not sure.

If you start to see artifacts even with 1 or a few increases try .10 volt increases.

But, this is also relative to what your VID is by default as it might be higher than others and you'd have less headroom to increase. Download TechGPU and see what it says for VDDC, run a video as it monitors so the card is actually using it's 3d clock speeds and not 2d so the proper voltage that it's using with 3d clock speeds will appear.

you should get 950mhz with no voltage is my guess.
hawk stock is 950, and twin frozr SOC is 950, so try that smile.gif

But you can put the voltage up just make sure you cooling the power area

i also own this card. at first i got greedy with a 1ghz core and 2300 memory. it seemed stable, but ever since i updated to the new drivers (270.61) i keep getting crashes. the odd thing about them is the video will freeze for a few seconds, then return with no audio. i now can only get a 930, 2100 without any crashing.

First of all, download and use the NEWEST MSI Afterburner software.

Use that to tweak your clocks. Many people report 925-950mhz core and 2200 memory on stock voltages. Personally, my card takes 1.1v to run stable at 980 core and 2250 memory, but it is a not a particularly good OC'er.

I'm not a fan of GPU overclocking....

I did a quick benchmarking run at 930MHz (instead of 880mhz) stock volts...no issues...haven't touched the vRAM...that's with a pair of 560Ti twinfrozr II OC

It led to a small 200 points increase in 3Dmarks11 P-score...hardly worth it...I could push it more, but I'd rather not too...with two cards, I don't need the OC boost...

What's a good GPU testing program?

^This^

For testing OCs some use Kombuster which is bundled with Afterburner. I prefer to use Heaven, 3dmark Vantage and an unlocked 3dMark11 which allows an individual test to be continuously looped.

I can run my 560 TFII stable at 925/2200 using stock voltages. If needed I'll run 950/2200 at 1.035v; my max stable is 980/2200 at 1.087v using the 270.61 driver.
