Once you've got a stable clock do you...

Once you've got a stable overclock on your gpu do any of you guys bump up the voltage a little bit more? Say you got 900core stable at 1.08v do you bump it up a tad more to 1.082v just to be safe?

Also what's the impact of having high clocks in the long run?

na, as long as you've stability tested it for a sufficient amount of time you can leave the voltage.

your hardware may degrade quicker, there's no way of really telling how long it will last anyhow though, it also depends on the clock and voltage you put through it...

Is this also true for hardware thats been specifically designed to be overclocked?

Pumping more voltage through any component will shorten it's life by a certain margin but unless ur really pushing silly volts through it i doubt u would notice it.

Hardware isn't specifically designed to work at 1 stock speed, which is why overclocking is so easy to do on most components.

That's a fair point, I just always thought that hardware that's been built from the groud up specifically for overclocking and overvolting would last longer and perform better than a reference model.

Well their quality control works out the best clock rate and voltage which 100% of the silicon should perform at and go from there. You can go under or over it by x amount depending on the quality of the silicon in question usually and some chips are vastly more tolerant to higher voltages than others. Thats where the "cherry picked" term comes from

If a manufacturer doesn't want their product overclocking, they can lock it on the hardware level, like the i5 2500 vs the i5 2500k models.

Stable over clock? Time to build another system

Stable over clock? Time to tighten memory timings and reduce voltages and heat

Jay85 · 14 Aug 2011 at 00:12

No no my overclocks are fine and heat is also well below the norm idle and at load (load being more important). My cpu overclocks are also perfectly fine but i'm using the OC Genie switch instead of doing it through the bios... i just find it easier and hassle free.

Memory timings i've always left at default which is 1.5v and never needed to overclock it at any point.. find it abit pointless unless running an intel system.

Nah that's voltage. Memory timings are like.... CL 9-9-9-10 stuff like that

Jay85 · 14 Aug 2011 at 12:33

My bad lol, i meant voltages not timings.

While we're on the topic of memory, does AMD memory controllers only support upto 1333mhz speed? I noticed their boards can overclock to much higher speeds but is there any point if the chip can only do 1333?
