Over clocking increment question

[borley]

Hi just some questions about increments on overclocking, I see with core clock most people seem to go up in 10mhz increments, some people jump as much as 100mhz at 1st then they fine tune with 10mhz increments.
But I have seen people with cores like 1206mhz!
So do people go as low as 1mhz increments?
Also voltage what increments do they use? I see some people are using 0.06mv.
Is there a science why you might use 0.06mv?
Thanks

Start off rough and then fine tune, its like anything if you do it enough you will know the limits of your card down to a single mhz or mv

For instance I initially clocked at 1350mhz which was agressive but it passed so went 1375mhz and it failed. 1360mhz okay in heaven but fail in 3dmark, 1357mhz solid in both.

Same with memory, I go agressive, make the driver fail and then clock back and find the sweet spot.

I do big 100 mhz leaps first, then 50mhz once I hit the 100mhz increment limit. Then that goes down to a further 10 mhz... Although I usually pull it back to the lower 100th for the "stability" headroom.

absolutely, the clocks in my original post are kamikazee 100% fan benchmark runs.

My 24/7 clocks are 1300mhz / 7000mhz, quite a big reduction.

Hi thanks for the replies that what I was thinking if you clock to within 1mhz then there's more chance for a crash in a game where as if you round it down less chance of a problem.
Thanks

yeah drilling down to that kind of fine tuning is for e-peen benchmark runs mainly mate although its nice to know where the limits of your card are so you can set a decent but 24/7 safe overclock.

I went up in 20's untill failing and then went in 1's. I wanted to see my max OC and had the patience in doing so
