Overclocking - Woppet* - 11-26-2011
Does anyone here know anything about overclocking GPUs?
I'm having a lot of trouble and i need some help.
If anyone knows anything i'll reply with my problem and all the details.

Well, which chipset is the card - NVidia or Radeon?
I use MSI Afterburner to overclock my GPU. A lot of the newer ones have some kind of software in the box to do this, but Afterburner has all sorts of options:

Ok basically i'll post here what i posted /g/
Quote:I just bought an Asus 1GB GeForce GTX 560TI DirectCUII PCI-E
The rest of my specs are in the attached image.
I have literally no experience with overclocking and i was wondering if you guys could help me.
I downloaded afterburner like a friend told me to and the defaults were as pictured.
I followed an OC guide for my card which told me to set the values to 1GHz for the core, 2GHz on the shaders and 1200MHz on the memory.
However after doing this i didn't notice any raise in FPS in the games i tested (GTAIV, Skyrim and WoW) But i did notice big slowdowns on occasion, and one instance where wow's fps shot up to 1000 before immediately crashing. I've also experienced windows freezing multiple times.
Do any of you guys know what i should set the values to to get everything running smoothly again? Is there some huge problem with my hardware that's preventing me from OCing effectively?
Thanks in advance guys i am seriously stumped with this and i have literally no idea what to do.

This is one of the fundamental issues with overclocking, basically what you're doing is forcing the hardware to run at speeds it wasn't designed for, which can be a little unpredictable if you're not entirely sure what you're doing.
The main downside to overclocking is that it can severely lower the lifespan of your hardware and it will generate a lot more heat (I've actually UNDERclocked hardware for the same reason before), and as you've found out, can make things very unstable depending on what you do.
The amount you're overclocking by is pretty severely over the stock clock speeds, unless you're working in a perfect environment for it the thing's just gonna overheat and die, I'd suggest you try gradual tweaks rather than jumping straight to the limit.
It's easy enough to do, just grab whatever benchmarking software you prefer, and fiddle until you find the sweet spot, basically making small increments until you notice stuttering or your card starts running too hot.
That said, unless for some reason you're desperate to run everything at maxed out settings, I can see much need to overclock that card.

Yeah, when I was trying to find the sweetspot on my card I would just raise everything by 50, run a game and see how it works. I found with my card you could tell when it had gone too far because it would blip colored lines onto the screen.
A few days ago I was in a game and it was freezing every two minutes, checked the card and it was running at 70C and somehow the clocking all got turned to max.
