Help o.c 560 ti oc sli

[jdfox]

Hello again, so my 2 monitors and Nvidia 3D vision kit has finally come so i now have 3 BenQ 23" 1080p true 120hz 3D l.e.d monitors hooked up to 2 Gigabyte GTX 560 ti oc sli 900/2100/1800 and would like to o.c them further than the factory o.c as i have read many times the 560ti oc is really good for overclocking. i am using msi afterburner but i have no experience upping the gpu voltages and would like to get it around 1000/2000/2250 as these oc has been achieved by alot of people using the same card on the stock cooling which is dual windforce fans which i have running @ 100% and cannot hear them at all since the upgrade ive lost around 10 fps on bf3 a bit more on mass effect 3 and various other games i know upgrading the gpu would help but i do not have funds for this at the moment due to building a proper gaming system so will have to do for now. so if you can help out fire away

Well, not sure if you will be able to reach your 1k goal...as sli/Crossfire doesnt normally allow the same clocks as a single card.

With that said, what I would do is add .1v to both cards, and see how far you can push them. Overclock them together. Core first, once you find its maximum, back off around 20Mhz, then do the memory.

Well you was right about not reaching 1k on the gpu clock but i managed 950/1894/2150 on both seems to be running ok jst had to up the volts to 1.000mv from 0.985mv gained a few fps back thinking i will upgrade psu to a 850w insted of using a discrete 650w for one of the cards

EVGA Precision X

MSI afterburner is dam good but i like the EVGA Precision X along with EVGA Voltage Tuner and EVGA O.C. Scanner that came with my gtx 560 ti's (also running sli) i got my gpus at 980 gpu clock/2100 mem clock and at 1.1v. the best thing about Precision X is that you can set what fps you want and it will automatically try to get that for you. i set it to 75 but only got 69 fps but that's still good. I got the gpu clock to 1050 before but then it was slightly unstable on crysis so i just backed off alot and settled with 980.

Try this software and you might get alittle extra out of em

awsome stuff them programs got it up to to 965/1930/2175 but only gained 2-3 fps i guess having 1GB cards is just not enough for 3D surround ive decided to sell these cards off to a m8 for £250 and buy 2
Gainward GTX 680 2048MB 2GB will set me back alot but they will be awsome for my current project. I,m just hoping my 2600k @ 4.5ghz will not bottle neck them too much untill IB comes out

GTX 680, damn that would be awesome to have, and your cpu should be just fine for em, i originally wanted the x58 chipset but they went obsolete as soon as i tried to build my comp. i gotta see about getting me 2 gtx 600 series cards.
