EVGA GTX 560ti DS overclock using precision

[Walshire]

Hello

Im trying to squeeze every last drop of performance out of my system, i have managed to get my CPU where i want it, but my graphics card wont let me take it higher than 970 core, 2206 memory and voltage 1.75, i have tried increasing the voltage to the next setting which is 1.100, then taking the core up to 972 but even that causes a fail, my CPU is a 975 phenom II BE, running at 4.2ghz, voltage 1.46, max temp on full load 54c, ive read that some people are able to get the core on the 560ti DS to 1000 or above!

Any help plz?

You have to remember, each chip is different so where one will goto 1050, another will not go past 900. 970 is a good OC TBF

Thanks for the quick reply,

I get a score of 4977 on 3d mark 11 performance test, wanted to hit around 5000 but i know i cant take the CPU any further, not for 24/7 use anyway.

Would taking down the memory clock allow an increase on the core clock or would you say my settings are sound as is?

I take it you meant 1.075v rather than 1.75v?

1.125v is still a safe level for a 560 Ti, as long as your temperatures are ok - i.e under 80-85, although the cooler the better obviously.

And you will only really notice a difference in benchmarks by clocking the ram, and even then by 50 or so points if you're lucky.

Dropping the memory to stock clocks will lower your 3dmark score, but you might gain an extra 1-2fps in games if you can squeeze another 50+mhz from the card.

Just need to ask yourself is it worth it?

I wouldn't be too unhappy though, as 970mhz is still a pretty good overclock for a 560 Ti. If you look at reviews most cards hit 920-980mhz.

Very few manage 1ghz+, and even if they do the fps gain is minimal for the voltage required & the extra heat / noise output.

Hi, yeah, sori 1.075 is wot i meant lol

Since being on here yesterday, i managed to reach a 3d mark of 4995, i did this by doing as you say, increased the voltage to 1.125, got the core to 980, kept the memory at 2206, had to also increase the CPU voltage to 1.47 as it failed the physics part after the increase, but its stable now and im really happy, ive got decent cooling, max CPU temps of 55c now, and the card as you say 85c max using a custom fan curve.

This is my first build, bought June 2011, i knew nothing about overclocking when i first put this all together, infact putting it all together i didnt really know what i was doing either really, had to have a friend come over and check it before switching it on lol, over time ive managed the cables, added an old 180gb IDE HDD from my old store bought pc, and my latest improvement was cooling.

Xigmatex Asgard case
Asus M4N75TD mobo
Silverstone 1000w PSU
AMD 975 Phenom II BE @ 4.2Ghz
4gb Corsair Dominator GT 2133 @ 1600Mhz (cant find anymore of these to upgrade to 8gb)
Antek H20 620 (added a scythe gentle typhoon 1850 for push pull)
60gb OCZ agility 3 SSD
2TB Hitachi HDD
LG GGC-H20L Super-Multi Blu-Ray Drive
EVGA GTX 560ti DS @ 980Mhz core 2206Mhz memory

I have another 2 gentle typhoons pulling air in top and bottom at the front of the case and the stock case fan pulling hot air from the graphics card out of the side.

Thanks for you're help guys!

For the sake of 30mhz, I'd be tempted to drop the voltage and get it stable at 950mhz.

You'll have lower temps, less fan noise, you won't notice any difference in games but your ears & gfx card will thank you for it in the long run.

I have taken the core 30Mhz down to 950 and voltage to 1.075, is the memory clock ok at 2206?

Saved the 980Mhz settings for benchmarking, just gotta remember to increase the voltage, is there a way to set the voltage to change automatically in precision when switching profile?

It should be. If you're not getting any crashes in games, or artifacting, then it is.

Not at the moment afaik. EVGA have said they're working on it :

try using the msi afterburner it saves the voltage on a profile

been playing around with my 560ti aswell got mine to 1000mhz core and 2200 memory 1.050 core voltage

anything over 1000mhz for the core tho i get a crash
