Overclocking experience

From your experience, which was more damaging: overclocking the core or overclocking the memory?

Assume that you're overclocking both, did you push the core to more heat than it can run stable or did you push the memory that you aged them prematurely?

It seems that I tend to be able to overclock geforce cores further than their on-board mem (2ns, 2.2ns, etc).

Different story with ati boards where I can't get good clocks with core using stock hsf.
 
i'd assume the memory was the more dangerous, seems to leave permanent artifacts sometimes i think.

I only did that one time wherein I went overboard clocking the memory of 5900. I specifically bought an evga knowing that they were the few ones using the 2.0ns samsung bfg. ran it for a couple of hours and always had artifacts in farcry "river" levels. anomalies go away if I underclock memory and leaving the core at same overclock.
 
i agree that anybody can go buy aftermarket hsf to cool core but ram heatsinks aren't all that effective.

but with newer cards like x800 and 6800, these gpu's make the ram freq the bottleneck so its the mem that need to be overclocked and not necessarily the core.

Depends entirely on the card, there's no rule in overclocking, each card is different even if they're the same model.

so what's your own personal experience?

 
I had no real luck OCing my old Ti4400 or 9800 Pro, but my new X800 pro (stock cooling) seems to OC well. Default is 475/450 and it gets over 530/550 without artifacts, but I just keep it at 520/520 - I don't like to push my luck.

This boost my 3dmark from ~4300 to ~4700.
 
Generally speaking the core can't be permanently damaged as it usually shuts down/crashes if it's pushed too hard. Memory OTOH can be damaged.

I usually avoid overclocking completely.
 
Well I heard about people going as high as 580Mhz for the core of a stock-cooled X800Pro.
I actually don't overclock, but you can go to Futuremark's ORB and see what people are getting with their cards, every single card is listed there.
edit: oh wait, when I overclocked my previous video card (POS MX 440) it got as high as 305Mhz core/470Mhz mem up from 270/400, pretty impressive, huh? 😛
