Also, I have seen a lot of people say they had considerable FPS gain by having a high memory as opposed to only core/shaders.

Going from 940/2250 to 950/2150 I lose 5 fps in the opening sequence of Heaven benchmark.

How much do you gain going from stock to 2150? When I get my water block on I am going to max this card out. Just curious if it is really worth trying.... Been busy at work and have not had a lot of time.....

Hey guys, I though I would share my ghetto mod for the classified 448. I took the stock fans+shroud off and strapped 2 120mm fans to the heatsink. Because the classified is a little bigger than 2 slots anyway there is nothing to lose, now it is like a 2.5 slot card. Temps are at least 5 degrees cooler, but most importantly it is nice and quiet. Plus it is nice and easy, just need some zipties.

Hi guys!

First time posting on overclock.net.

I just received yesterday a lovely, lovely msi GTX 560 448 Twin Frozr III Power Edition (OC). It's already installed and giving me plenty satisfaction over my former GTX 260. Haven't run any benchmarks yet (my game time is fairly limited so I didn't want to waste my first evening fudging with settings). Temperature was around 53°C after an hour of Final Fantasy XIV (not the most graphically optimised software), dropped to 40°C in mere seconds, very silent cooling!

First of all, there's over 800 posts in this thread, I haven't read everything, neither do I intend to, so don't snap at me if I missed something around page 43 or whatever. I'd like to try my hands at overclocking this little beauty, at this stage I'm mostly collecting info.

So far, I've gathered that:
• msi After Burner's voltage control is locked by default, needs to be unlocked from the settings menu
• Pushing the voltage slider up to max won't harm the card, but temperatures need to be closely monitored as clock speeds are increased, since the extra voltage will quickly crank up the temperature. Only add as much voltage as needed for stable operation at the target clock speed.
• Most cards can go up to 850/1700Mhz on stock voltage, anything higher than that usually requires a little boost.
• Some people managed to push up this card all the way up to 1GHz, but the most common, stable average is around 900/1800Mhz with a little voltage boost (1.025-1.075).
• It's hard to get a stable increase in memory speed, some say it's worth it, most say it's not. I probably won't mess with that, personally.
• Good benchmarks to stress test the overclock settings are 3DMark11, FurMark, msi Kombustor, Heaven Benchmark, and games, games, games!

I'd like to ask:
• Has anyone busted their card following excessive OCing attempts? Does experiencing artifacts indicate a risk of damaging the hardware?
• Would it really be an issue if I just straight up assumed that since most people can manage 900/1800/1950 @ 1.050-ish V, odds are good that it'll work for me? In all honesty, 20% increase in clock speed is more than enough for me, I'm not trying to push it to it's very limits and unfortunately don't have the time to min/max digits and stare at benchmarks until it works, I'm just looking for a nice, safe, stable, sure-to-work overclock.

Regarding the rest of my setup:
• Antec Sonata III case, clean cable organization with no fan obstruction. Recently cleared of dust.
• Corsair TX850 PSU (hurray for extra juice! Sonata III's stock PSU is 550W I think?)
• Gigabyte GA-P55-UD3
• Intel Core i7 860 (running at stock 2.8 Ghz, contemplating overclocking it to 2.93 like an 870, just for the heck of it. I don't want to mess with replacing the cooler, so that's probably all I'll get from sticking with the stock cooler)
• 12GB RAM (2x4GB, 2x2GB, despite screams of terror from some of my friends for mixing bars with different capacities, they're paired correctly and I've had 0 issues with them)
• Windows 7 Professional 64-bit

So... did I miss anything crucial before I begin?

Great thread, by the way! Everyone is so passionate about their card(s) smile.gif

Looks like you did your homework. Everything looks good to me. As for damaging the card, most have a fail safe when they reach a certain temp they should shut down., As for artifacts hurting the card, I would say no. More of an indication that the card is being pushed a little to much. As for oc'ing the card, I know it's easy to jump into it and set it at what most run but in all honestly you will do better and learn more if you start from zero. Start with the core/shader and see how far it will go on stock voltage. Then bump the voltage up a notch or two and start with the core/shader again. Go until your card cannot go any further or where you feel comfortable at based of performance. Then once you find these settings is when you can mess with the memory. For me staying in the 5% range is good enough but your more than welcome to try more. Run benchamarks/stress test while doing this and you can see how much you gain.
Also congrats with your system and card, you will most definitely like it and may even want 2.thumb.gif

Unfortunately, although the GA-P55-UD3's second slot can accommodate a second GPU, it runs at 4x and not 16x like the first slot, I really wouldn't go SLI on that... I've read about people running a second card on the 4x slot as a dedicated PhysX card with very appreciable results. Might just do that with my old GTX 260 if future games actually decide to work with PhysX, most don't.

Thanks for your tips smile.gif Would you recommend a specific benchmark over another? I've seen what artifacts look like on FurMark, but I think Kombustor (almost wrote "Komposter" LOL) also uses furries?
